Compositions for applying coatings with decorative effect, preparation and deposition methods thereof

FIELD: chemistry.

SUBSTANCE: invention relates to coating compositions, particularly coating compositions with a decorative effect, which enable to obtain multi-colour and/or different-tone surfaces when applied once. Initially, the single-colour coating composition contains a first dye, a thickener, a surfactant or a mixture of surfactants with hydrophilic-lipophilic balance (HLB) less than 9 or greater than 11 and binder. All components are dispersed or dissolved in an organic solvent and water. After deposition of the said composition in form of a film onto a substrate surface which is a wall or ceiling panel, the first dye becomes incompatible with the said composition, as a result of which a portion of the first dye migrates towards the outer face of the panel while the coating composition is still in liquid state. Additional decorative effects are achieved by sliding the surface using a putty spittle or some other instrument while the coating composition is still in liquid or quasi-liquid state. The set for applying the decorative coating onto the surface contains the said composition and a label.

EFFECT: obtaining a ready coating having two differently-coloured zones, colour contrast (ΔE) between which is greater than 0,25.

The invention relates to compositions for coating and, in particular, to compositions of coatings with decorative effect, allowing to obtain multi-color and/or raznotonnye surface in one application.

Most of the existing compositions for the deposition of decorative coatings allow you to get a solid color or a solid surface. Therefore, often requires repeated application of different coating compositions, when you want to get multi-colored coating. Alternatively, consumers can use their existing multicolor composition for coating, which allows to obtain the necessary multicolor decorative effects in a single application.

In U.S. patent No. 3058931 described composition for applying multicolor coatings, to get the mottled coating in one application. This coverage includes "water-based", containing a protective colloid, one or more pigments necessary for hiding power and control the gloss of the final product, and emulsion polymer. Pigmented lacquer binder is prepared by rubbing colour pigments with a lacquer binder resin. The contrast between the large, macroscopic pigmented lacquer particles and colorless water basis in the final composition allows to obtain cu is poatoe coverage in a single application. In the mentioned patent emphasizes that the pigmented lacquer binder should have a hydrophilic including at least one less than 60 (or hydrophilic-lipophilic balance of less than 12) to prevent the collapse of macroscopic lacquer particles and obtain the mottled appearance of the coating. In addition, since this composition for coating does not always guarantee getting speckled surface, it does not meet the requirements of consumers to create the necessary decorative coatings.

In U.S. patent No. 3811904 shows another composition for coating, which also allows to get a mottled coating in one application. Composition for coating contains spherical particles of solvated polymer, tinted by adding pigment to polymer crosslinking. In stable suspension of spherical particles of crosslinked polymer dispersed in the liquid with which they to some extent are not mixed, and not coalescent with each other. As a result, a stable spherical particles of the colored polymer give speckled floor. In the paper slurry composition for coating contains two solutions (or continuous phase and a disperse phase) is incompatible polymers, which are also colruyt pigment addition on the stitching. Spherical polymer particles of the dispersed phase are merged with each other, forming particles of a larger size, resulting in a speckled floor. In addition, the surface with veins can be obtained by shifting the coating while it is still wet, and because of the dispersed and continuous phase (i.e. both polymer solution) have fluidity, not mixing. However, due to the nature of spherical particles, the surface of the resulting coating is allocated to the General background streaks and color breaks in the shift.

In U.S. patent No. 3600346 it comes to compositions for coating multi-color coating with grainy and rough ("aged") surface in one application. Composition for coating contains a primary pigment, dispersed in a binder based on alkyd resin modified with oil. The composition further includes a secondary pigment encapsulated in the resin immiscible with the binder based on alkyd resin modified with oil. The application of shear to the wet applied coating leads to the exit of the secondary pigment from its resin capsules (or "shell"), thereby providing a granular or aged appearance of the final coating. As in the case of spherical particles in U.S. patent No. 311904, the nature of the encapsulated particles of the secondary pigment causes the surface of the final coating is visible on the General background of veins and color breaks in the shift.

The aim of the present invention is the creation of original monochromatic compositions for coating or ink containing at least one dye, and methods for their preparation. Originally proposed by monochrome compositions for coating, brewed in such a way that part of the coloring matter (substances) is incompatible with the other components of the composition for coating, resulting separated, concentrated, forms flakes and/or emerges from the applied coating composition on the outer front surface being formed of the coating, while the composition is still liquid and/or quasi-fluid state (i.e. up to the moment when the composition for coating completely dries, forming a "floor"), thereby forming the final (or formed) coating multi-color and/or ratnatunga appearance with one application. Thus, the proposed originally monochrome composition for coating according to the invention eliminate the need for multiple execution stages of the application and/or use the various products (such as various monochrome compositions for coating), allowing you to get the finished coating, giving the desired decorative effects, including, but not limited to, iridescence and/or many shades. Mainly, originally monochrome compositions for coating can be applied to any traditional method of painting surfaces: brush, roller, spray, etc.

In one of the embodiments of the invention, originally monochrome compositions for coating form a multi-color and/or raznotonnye end surface in a single application, due to the sensitivity of the applied composition to shear in the liquid and/or quasi-fluid state. This exercise involves the application of shear, increasing instability or incompatibility pigments with other ingredients of the composition and, consequently, the shift can be made selectively for the formation of certain sections with different color (or pattern) in the end formed the floor. More specifically, the application of shear to the surface of the formed coating mainly increases the amount of coloring substance (s) and/or is the cause of their separation, concentration, formation of flakes and/or floating on the surface of the formed coating while it is in liquid and/or quasi-fluid state, so about the time, making the shift to the selected portions of the forming surface, to obtain patterns in the finished coating and/or to achieve a desired decorative effect on certain areas of the coating. The shift can be accomplished by any means, including, but not limited to, the use of hand tools, such as spatulas and brushes, and using a sponge, cloth and/or even your hands or fingers, etc.

In General, the terms "liquid state", "quasi-fluid state, and the liquid and/or quasi-fluid state" used in this description to indicate that a composition for coating is not formed in the final coating. In the process of drying the coating changes from liquid to solid by evaporation of the solvent and/or due to physical interactions and/or chemical reactions in the binder [Coatings Encyclopedic Dictionary, S.Le Sota, Ed., Federation of Society for Coatings Technology, Blue Bell, PA., 1995].

In one variant embodiment of the invention, the terms "liquid state", "quasi-fluid state, and the liquid and/or quasi-fluid state" means that the composition for coating is not dry completely or not hardened. According to the definition adopted in the production of coating composition for coating is hardened (and formed in the finished coating), if any trace from the application of the maximum possible for this coating (or film) pressure remove a light buffing with a soft cloth [Coatings Encyclopedic Dictionary...].

In another variant embodiment of the invention, the terms "liquid state", "quasi-fluid state, and the liquid and/or quasi-fluid state" means any time before the composition for coating dries to the point where it will be dry to the touch. According to the definition adopted in the production of coating composition for coating becomes dry to the touch when the internal cohesion of interaction in it becoming stronger adhesion interactions compositions for coating the surface of the substrate. To determine whether reached or not reached the floor this point, you can use a simple touch: the floor should be dry, not sticky to the touch [Coatings Encyclopedic Dictionary...].

Thus, the shift is usually applied to the coating after application of the composition to the surface and before the composition is completely dry. Typically, the offset is applied after about 30, about 45, about 60, and/or about 90 seconds after application of the composition, and up to the moment when it becomes dry to the touch (i.e. while the coating is still tacky to the touch). Of course, the time required for complete drying of the coating and/or drying it to a state of dryness to the touch, varies depending on the thickness of the coating, as well as the nature and porosity of the concrete under the Oki, however, it can be easily identified by the above methods.

Typically, the coating having a thickness of wet film is approximately 25.4-254 microns (1-10 mils), provides the finished coating having a dry film thickness about to 12.52-125,2 microns (0.5 to 5 mils). Such coatings harden completely in about 30-60 minutes under normal drying conditions (25°C (77°F) and 50%relative humidity)and dry to the touch become approximately 1-10 (usually after about 1-5 minutes after application when the same normal drying conditions.

In another variant embodiment of the invention, when the composition for coating is in a liquid and/or quasi-fluid state, the shift is not applied. This option involves drying originally monochrome compositions for coating with the formation of the finished coating with speckled, spotted or other colour contrasts surface. As in another embodiment of embodiment (with shift), achieved decorative effect is due to the incompatibility of the coloring substance (s) with other components of the applied composition. However, compositions for coating in this embodiment, embodiments of the invention are such that the original dyes are mixed with other components of the composition, but incompatible (with the other to what components of the composition for coating) since when the song starts to dry (that is, when it begins to evaporate the solvent and/or start the reaction in the binder) [Coatings Encyclopedic Dictionary...].

Thus, proposed by the present invention compositions for coating use instability or incompatibility dye substance (s) with other components of the applied composition over time as the composition is in a liquid and/or quasi-fluid state, which allows to achieve the desired color and/or ratnatunga decorative effect. As noted above, in different embodiments of the invention instability or incompatibility dye substance (s) with other components of the applied composition can be enhanced and/or compound by application of shear (e.g., using hand tools) applied to the coating composition, in liquid and/or quasi-fluid state. Instability or incompatibility dye substance (s) with other components of the composition for coating can be achieved in compositions with one dye, but the visual effects are more pronounced when used in compositions for coating the combination of (at least) the first and second dyes, immiscible with each other. Instability or not is sovmestimosti the coloring matter can be achieved by limiting or minimizing the amount of surface-active substances, dispersing agents and/or humidifiers in compositions for coating, since such components, as a rule, improve the compatibility of the dye substances from the components and/or systems for water and oil-based.

Visible and ordinary consumers decorative effects compositions for coating can also be investigated (and measured) by using conventional spectrophotometers. Such spectrophotometers allow us to "measure" the color settings, presenting the data in the format model description colour by the International Commission on illumination (CIE) - CIE (CIE LAB). Three parameters L*a*b* correspond to the three dimensions of color space". L* is the brightness setting, the ratio of black and white components in the sample, a* and b* are the color components of the sample. Color contrast or ΔΕ between two different colors (for example, two differently colored areas multicolor decorative coatings offered by the present invention) is in the range from 340 to 0 (no color contrast) and can be determined by measuring the chromaticity and the calculation of the color contrast on the basis of the following equation:

Minimum color contrast, differentiated by the consumer, is ΔΕ≈0,25, therefore, the proposed multi-color coatings or their parts, characterizes the Xia ΔΕ greater than this figure, provide the necessary decorative effects. However, as a rule, required indicators color contrast, significantly above the threshold of perception, because then they are more visible to the ordinary consumer, and decorative effects proposed by the present invention compositions for coating manifested in this case more clearly. Depending on the particular variant embodiment of the invention, the indicator ΔΕ offer coatings greater than about 1, about 2, about 4, and/or about 5. An excessively high color contrast is not always desirable, because then it becomes too hard for the average consumer or redundant for a particular decorative effect (for example, when you want a more subtle color transitions or raznotonnye coverage). According to that, in other variants of the embodiment of the invention the performance of ΔΕ of the proposed coating is less than about 200, about 100, about 75 and/or about 50. In other embodiments, implementation of the proposed coatings are characterized by an indicator of ΔΕ in the range of about 1.0 to 200, from about 2 to 100, from about 4 to 75 and/or from about 5 to 50.

Composition for coating typically includes at least one colorant, a thickener, a surfactant and a binder dispersed(or dissolved) in one or more widely used organic solvents and/or water. Compositions for coating typically includes at least one nicolardi pigment-filler/base. Moreover, compositions for coatings often contain anti-foam and moisturizing agents, and may include various other components.

As mentioned above, the visual effects are more pronounced if the composition for the coating contains a combination of (at least) the first and second dyes, which do not blend with each other. Thus, the composition of the coating may optionally include a second dye having physical properties different from the properties of the first coloring substance, so that the first and second colorants are not mixed with each other. For example, the first dye may be water and the second non-aqueous. Similarly, the first dye may be hydrophilic and second hydrophobic. In one variation of the embodiment of the invention, one of the dyes may be universal dye capable of salvationists and/or evenly dispergirujutsja both in aqueous and non-aqueous compositions for coating. When one of the dyes is a versatile dye, it is generally preferable that the second dye was basically incompatible(or immiscible) with the basis of the composition for coating (i.e. with a mixture that includes other components of the composition for coating).

The volume concentration of the pigment (GST) in the composition for coating represents the ratio of the volume of pigment (pigment) to the total volume of non-volatile material (e.g., aggregate pigment (pigment and binder) and typically is from about 5% to 95%, from about 10% to 80% and/or from about 15% to 65%. The ratio of pigment/binder in the composition for coating (total pigment/dry chemical binder), generally ranges from 25 to about 1, from about 20 to 2 and/or from about 15 to 5. However, it is usually preferred higher values of the GST and the ratio of pigment/binder because the higher pigment content provides additional sources of friction in the composition for a coating that can be used in situ to facilitate the development of the desired decorative effects. In addition, higher values can be useful for ensuring coverage of the finished coating and/or to increase the degree of penetration of the coating into the substrate.

Coloring matter (substance)

Composition for coating includes at least one dye, but more preferably, two coloring substances. Also the composition of the coating can contain three CRAs is related substances and more. Coloring matter (substance) may be aqueous or non-aqueous, hydrophobic or hydrophilic, or universal. Some colorants can be attributed to two or more of these categories. For example, the dye may be both water and versatile. Similarly, the dye may be non-aqueous and hydrophobic, or water and hydrophilic. The degree of color contrast and the color itself can preferably be adjusted by selection and concentration of the coloring matter (substances).

Coloring matter (substance) can be virtually any coloring substance, including, but not limited to, pigments and dyes, provided that at least one dye (or part thereof) must be capable of separation, concentration, chapeaurouge and/or coming to the surface is still wet, emerging applied composition, giving in the end, prepared or formed by coating with decorative effect in multi-color and/or raznochinnoj surface in one application. Often the dye contains a dispersed pigment. As used here, the term "coloring (ColorWise) substance" does not refer to a white, opaque pigments such as titanium dioxide or zinc oxide, which are defined in this application as "nekolera pigments filler/foundations of the. However, in accordance with the invention, the colorants can consist of a dispersion of a white, opaque pigments (such as titanium dioxide and zinc oxide), which is able to separate, to concentrate, to form flakes and/or come out still wet applied coating composition to the surface being formed of the coating due to its incompatibility with other components of the composition for coating as described above.

If there is only one dye, it may be aqueous, non-aqueous, hydrophobic, hydrophilic or universal dye, but it is generally preferable that it is to some extent incompatible and/or unstable in forming the coating, is able to separate, to concentrate, to form flakes and/or come out still wet applied coating composition to the surface being formed of the coating. Thus, in compositions for coating solvent-based or oil, it is generally preferable to the use of water and/or hydrophilic dye substances (regardless of whether such dye universal dye substances). Similarly, it is generally preferable to use non-aqueous dyes and/or hydrophobic dyes in compositions for which Yesenia coatings, latex water-based (regardless of whether such dye universal dye).

As already noted, the composition for coating can additionally include second, third, and even more coloring substances. In all these cases, it is preferable that the second (or third) the dye had physical properties that are different from the physical properties of the first order at least two of the dyes are essentially not mixed with each other (i.e. mixed less than 10% wt., 5% wt., and/or 2% wt. collectively, the agents). For example, the first dye may be water and the second non-aqueous. Additionally, the first dye may be hydrophilic and second hydrophobic. Alternatively, one of the dyes can be flexible, able to salvationists and/or evenly dispergirujutsja both in aqueous and non-aqueous compositions for coating and other coloring matter may be selective for either aqueous or non-aqueous system.

If one of the dyes is universal, it is preferable that the second was relatively incompatible with other components of the composition for coating so that the second substance was able to separate himself, to concentrate, to form flakes and/or VSP is Ivate still wet from the applied coating composition to the surface being formed of the coating. Thus, in compositions for coating oil-based, including universal dye as a second coloring substance is generally preferable to use water or a hydrophilic dye. Similarly, in compositions for coating based latex containing universal dye is generally preferable to the use of non-aqueous or hydrophobic second coloring matter.

Suitable for COI is whether hydrophobic coloring matter, as a rule, contain at least one pigment dispersed in a hydrophobic resin basis. In the hydrophobic resin bases can be effectively dispersed both organic and inorganic pigments. In one embodiment of the invention, a hydrophobic dye contains approximately 100 wt.%. dry matter. In an additional embodiment, the resin is an unsaturated complex polyester, functionalized with hydroxyl groups, is highly compatible with the usual complex polyester and vanilladeville resins. However the invention is not so much the chemical composition of a suitable hydrophobic coloring matter how long its immiscibility with the aqueous solution (or system). Similarly, important not so much the composition of the hydrophobic resin base, as the degree of hydrophobicity. Examples of hydrophobic dyes are products manufactured under the trade name POLYTREND®(Degussa Corporation, USA).

Suitable non-aqueous dyes contain, as a rule, at least one pigment dispersed in the combined system of an organic solvent and resin. In such a system can be effectively dispersed both organic and inorganic pigments. In one variant embodiment of the invention, the solvent used in the t mixture propilenglikolmonostearata and natalspruit (naphtol spirits). In another embodiment, thermoplastic resin is, for example, thermoplastic acrylic resin. Suitable non-aqueous dyes can also contain one or more surfactants. Suitable non-aqueous dyes are generally compatible with many non-aqueous coating systems, including alkyd and epoxy resins, cellulose lacquers, polyesters, and polyurethanes. For the effectiveness of non-aqueous coloring matter in the proposed compositions is not so much its chemical composition, as its immiscibility with the aqueous solution (or system). Examples of organic pigments are products manufactured under the trade name : CHROMA-CHEM®(Degussa Corporation, USA).

Suitable universal colorants are compatible or miscible with both aqueous and non-aqueous solutions (or systems). These dyes often include at least one pigment dispersed in an aqueous or nonaqueous solution, and do not contain resin. You can include organic and/or inorganic pigments. The versatility of concrete coloring substance is determined by its behavior in aqueous and nonaqueous solutions, not chemical composition. Examples of universal pigments are products manufactured under the trade name COLORTREND®(Degussa Corporation, USA).

Under adamie hydrophilic dyes contain, typically, at least one pigment dispersed in the hydrophilic resin basis. Suitable hydrophilic resin bases can be effectively dispersed both organic and inorganic pigments. In one embodiment of the invention, the hydrophilic dye contains approximately 100 wt.%. dry matter. In an additional embodiment, as the resin is polyamide or polyurethane. For the essence of the invention is important not so much the chemical composition of a suitable hydrophilic coloring matter how long its immiscibility with nonaqueous (or system). Similarly, important not so much the composition of the hydrophilic resin bases, but the degree of its hydrophilicity.

Suitable water dyes typically contain at least one pigment dispersed in the combined system of an aqueous solution and resin. In such a system can be effectively dispersed both organic and inorganic pigments. In one embodiment of the invention, the resin is an acrylic resin. For efficiency, water coloring matter is not so much its chemical composition, as its immiscibility with nonaqueous (or system). Examples of water pigments are products manufactured under the trade name AQUA-CHEM®(Degussa Corporation, USA).

Zag is stitely (thickeners)

To obtain the necessary rheological properties of the composition for coating include one or more thickeners. For example, the thickeners are often used to obtain compositions for coatings with viscosities of from about 50 to 140 units Krebs (KE), from about 70 to 120 KE and/or from about 80 to 110 KE. For measuring the viscosity of compositions for coating, you can use the viscometer of Stormer. Thickeners suitable for use in the original monochrome compositions for coating include, but are not limited to, cellulosic thickeners, clay with gelling properties, associative thickeners, and combinations thereof.

Examples of cellulosic thickeners used are not limited to, ethers of cellulose having a molecular weight of 1000-500000 daltons, for example, alkylhydroxylamines cellulose, hypromellose, xanthan gum, carboxymethylcellulose, hydroxyethylcellulose, sodium alginate and other salts of alginic acid, carrageenin, gum Arabic (of the Arabian gum), gum karaya (acetylated polysaccharide), tragacanth gum (a complex mixture of acidic polysaccharides), gum, ghatti (calcium and magnesium salts of complex polysaccharide), guar gum (nonbranched galactomannan) and its derivatives, gum Bobo the carob tree (branched galactomannan), tamarind gum, gum plantain seed, gum seeds of quince, larch gum, pectin and its derivatives, dextrans, and hydroxypropylcellulose. Originally monochrome composition for coating contains from about 0.01 to 5 wt.%, approximately from 0.05 to 2.0% wt. and/or from about 0.10 to 1.0% by weight. cellulose thickener.

Alkyl group suitable hydroxypropylcellulose can contain up to 9 carbon atoms, but usually contains one to three atoms. Often use hypromellose, with an average of two hydroxyl and/or methoxypropyl group in anhydroglucose link. The viscosity of an aqueous solution containing about 2% wt. suitable alkylhydroxylamines pulp, measured using a capillary viscometer of Ballade at 20°C is about 60000-90000 CP. Alternatively, a similar measurement can be carried out using a rotational viscometer Brookfield at a speed of about 2.5 and about 5/min In one embodiment of the invention, originally monochrome composition for coating contains about 0.25% of wt. alkylhydroxylamines cellulose. You can use other types of cellulosic thickeners, and the lower the viscosity of the thickener, the more maintenance it needs in the composition. Suitable alkylhydroquinones the Fira cellulose produced under the trade name METHOCEL ®(Dow Chemical Company, Michigan, USA).

As clay with gelling properties used in compositions for coating, use gormiti (hormite), including natural and/or synthetic spatial layered lamellar structure tetrahedral oriented silicon dioxide, which is connected parallel plates oriented octahedral aluminum oxide, magnesium oxide, and silicates and/or phyllosilicate. Such clays with gelling properties include, but are not limited to attapulgite, thick, bentonite, laponite, nontronite, beidellite, yakhontova, cinxia, volkonskoit, hectorite, saponite, ferrocement, sekonic, swinford, pimelic, sobaki, stevensite, vermiculite, swelling in water, synthetic clays, smectites, such as montmorillonite, particularly sodium montmorillonite, magnesium montmorillonite and calcium montmorillonite, illite, mixed layered, illite-smectite minerals, such as rectorite, tarasovic and medikit, silicates of aluminum and magnesium, and mixtures of the listed clays. Preferably the use of palygorskite and attapulgite. Originally monochrome composition for coating contains about 0.01 to 10 wt.%, approximately 0.05 to 5.0 wt.%. and/or about 0.10 to 2.0% by weight. clay gelling properties. Suitable clay with gelling properties include the products, manufactured under the trade name MIN-U-GEL®(Floridin Company, Florida, USA) and ATTAGEL®(Engelhard Corporation, new Jersey, USA). Such clays are produced with different particle size.

Suitable associative thickeners used in compositions for coating include hydrophobizated ethoxylated urethanes (HEUR), hydrophobizated emulsion swelling in alkali (GANS), and triple-based polymers of styrene and maleic anhydride (TSMA). Thickeners GAUR (also known as PUR or PUR-associatedname thickeners) is used mainly in aqueous compositions for coating based on latex. As associative thickeners can also be used crosslinked acrylic acid copolymers of acrylate and methacrylic acids and crosslinked acrylic triple polymers of acrylate, methacrylic acid and non-ionic surface-active urethane monomer. When using one or more associative thickeners, the condensation reaction is initiated partly or Association thickener at least one other molecule composition for coating (for example, a pigment molecule or molecule resin), or with another molecule of the thickener. Depending on the particular embodiment of the invention, originally monochrome compositions on the I coating include about 0.01 to 10 wt.%, approximately 0.05 to 5.0 wt.%. and/or about 0.50 to 3.5% of wt. associative thickener. Suitable associative thickeners include sold under the trade name ALCOGUM®(Alco Chemical Company, USA), VISCALEX®(Ciba Specialty Chemicals, USA) and ACRYSOL®(Rohm & Haas, USA).

In one embodiment of the invention, the thickener contains GAUR and simple cellulose ether, such as alkylhydroxylamines cellulose. Assume, without going into theory that a combination of associative thickener and simple cellulose ether improves the quality of application and stability of compositions for coating during storage. For example, when using such a combination increases the smoothness of the coating and the uniformity of the layer deposited on the substrate. The combination of associative thickener and simple cellulose ether prevents the deposition of various pigments included in the composition for coating, when storing them in large quantities. Optionally, a thickening agent for a coating composition may include clay with gelling properties.

The thickener system is usually most effective in an alkaline environment. Therefore preferably included in the composition for coating of alkaline components to give a prepared composition for coating a pH of at least 8.0 in. To increase the pH using various alkaline material is ialy, including, but not limited to, ammonia, caustic soda (sodium hydroxide), triethylamine (tea) and 2-amino-2-methyl-1-propanol (AMP). Depending on the particular variant embodiment of the invention, originally monochrome compositions for coatings contain about 0.001 to 5 wt.%, about 0.01 to 0.5 percent by weight. and/or approximately 0.025-0,50% wt. the alkaline component.

Surface-active substance (substances)

Surface-active substances (surfactants) with hydrophilic-lipophilic balance (products HLB) of less than 9 consider lipophilic, having products HLB of 11 to 20 is considered hydrophilic, surfactant and with the value of the products HLB 9-11 considered intermediate. Sometimes in the composition for coating it is advisable to include not one, but a mixture of two or more nonionic surfactants. The products HLB values of surfactants have additivity, so products HLB surfactant mixture is easy to identify. For example, products HLB surfactant mixture comprising 40% by weight. the first surfactant having the products HLB value of about 15 and 60% wt. the second surfactant having the products HLB value of about 4,3, is 8.8, ie(15,0×0,4)+(4,3×0,6).

Composition for coating, latex, water-based, includes a surfactant or mixture of surfactants)having the products HLB value less than about 9. Typically, the surfactant is essentially non-ionic, i.e. contains more than 60 wt.%, more than 80% wt. and/or more than 90% wt. non-ionic surfactant molecules. Surfactant (or mixture is), with products HLB of less than about 9, less than about 7 and/or less than about 5, in General, preferred for use in compositions for coating, latex, water-based, because they form in solutions of micelles smaller, and therefore michelinie solubilizing or emulsifying interaction with coloring substances of the composition for coating easier to break. The destruction of such micelles coloring matter (substance), originally solubilization in compositions for coating, is released and therefore can be separated, to concentrate, to form flakes and/or to the surface of the applied (still wet) composition of coating on the external surface of the formed coating, providing the effect of color contrast in the finished coating.

In contrast, compositions for coating oil-based contain surfactants that rate products HLB of more than about 11. Surfactant (or mixture thereof), with more products HLB of about 11, more than about 13 and/or more than about 15, mostly preferred for use in compositions for coating oil-based, because they form in non-polar solutions of micelles smaller, and therefore michelinie solubilizing or emulsifying interaction with cu is generating substances in the composition for coating easier to break.

As in latex and oil compositions for coating the content of surfactant is reduced to a minimum to provide the desired visual effects, about which more will be said below. In General, the composition for coating application must include the amount of surfactant is at least sufficient for the formation of micelles in liquid form compositions for coating), and maintain the stability of the composition for coating (i.e. preservation of pigments and/or netoleruoja pigment (pigment) filler/basics essentially in dispergirovannom and/or dissolved in the liquid composition for coating). However, the composition of the coating should not contain the amount of surfactant necessary to ensure full svetootdachi, i.e. the implementation of all koleroga potential of the coloring matter (substances). Compared to conventional compositions for coating proposed by the invention composition, therefore, can be defined as compositions with reduced levels of surfactant. Typically, the surfactant is present in an amount of about from 0.01 to 5% wt., from about 0.01 to 3.0 wt.%. and/or from about 0.1 to 1.0 wt.%, based on the weight of the liquid form of the composition for coating application.

When the composition for the coating contains a surfactant in an amount sufficient for what Olney svetootdachi (i.e. excessive amount of surfactant), additional mixing or shearing will not change the color of the liquid composition for coating. Similarly, in compositions for coating contains too much surfactant, if a simple test for abrasion (for example, on the still wet coating impose a paper substrate and rubbed them the floor for about 10, about 20, and/or approximately 30 s after coating) does not lead to a noticeable change in color (compared with areas not Ter). Additionally, you can use ultrasonic spectroscopic analysis of high resolution to determine the critical concentration of surfactant (or mixture thereof)required for micelle formation in this composition for coating, and this critical concentration exceeds the maximum content of surfactant or equal to.

Nicolardi pigment (pigment) filler/basics

Nekolera pigments filler/basics not paint an original monochrome compositions for coating, however, they are used as background colors, compositions, thereby reducing the cost of the coloring matter (substance) and/or to change or improve certain properties of the compositions for coating (such as opacity, abrasion resistance, resistance to washing, resistance to scratches, the degree of absorption or penetration into the substrate and drying time). Thus, nekolera pigments filler/bases are not necessary to achieve multicolor decorative effect coatings of the present invention. In General, you can add any hard, inert mineral or like mineral filler/pigment filler materials/substrates, provided that the size of the particles is large enough not to negatively affect the characteristics of the fluidity of the composition for coating. However, the particle size is usually limited to avoid problems during the deposition. In the original monochrome compositions on the I coating add such nekolera pigments filler/base, as talc, gypsum (i.e. hydrated calcium sulphate, calcium carbonate, nepheline syenite, mica, whether kaolin clay, split kaolin clay, titanium dioxide, lithopone (lithophones), wollastonite and oxychloride bismuth, but not limited to these substances. Additional nemirowsky pigments filler/base, suitable for use in the original monochrome compositions for coating are fogging pigments, such as titanium dioxide and zinc oxide.

Depending on the particular variant embodiment of the invention, the average particle size netoleruoja pigment filler/basics of approximately from 0.1 to 150 μm, about 0.5 to 60 μm and/or from about 0.6 to 25 μm. Depending on the embodiment, the original monochrome compositions for coating typically includes from about 1 to 45 wt.%, from about 15 to 40% wt. and/or from about 20 to 35% wt. netoleruoja pigment (pigment) filler/base (total number). However, as a rule, originally monochrome composition for coating contains from about 1 to 30 wt.%, from about 2 to 20% wt. and/or from about 3 to 10 wt.%. any specific netoleruoja pigment filler/base.

Mica suitable for use in the proposed compositions have an average size cha is TIC (or an equivalent spherical diameter of the particles is from 10 to 150 μm, which have the form of flat plates. Fit is mica, manufactured under the trade name P-80F (United States Gypsum Company, Illinois). The average particle size of this mica is approximately 50 μm. In addition, approximately 97.5% of the particles of this mica have a size less than about 150 microns. The particle size can be determined by sedimentation analysis, for example, by using a particle size analyzer SEDIGRAPH™ (Micrometrics Instrument Corporation, GA) or by laser diffraction analysis, for example, using particle size analyzer SYMPATEC™ (Sympatec Inc., new Jersey).

The nepheline syenite particles are generally spheroidal. Suitable nepheline syenite is produced under the trade name MINEX®(for example, MINEX®7) (Unimin Corporation, Connecticut). Other suitable nekolera pigments filler/bases include, but are not limited to, the only manufactured under the trade name MISTRON®in particular, MISTRON®ZSC (Lucenac North America, Colorado); ground calcium carbonates produced under the trade name OMYACARB®in particular, OMYACARB®RT and OMYACARB®UF (OMYA Inc., Vermont); whether kaolin clay, manufactured under the trade name HUBER®including HUBER®70-C (Huber Engineered Materials, GA); hydrated silicates, manufactured under the trade the first name ASP ®including ASP®-400 (Engelhard Corporation, new Jersey); precipitated calcium carbonates produced under the trade name M-60 (Mississippi Lime Company, Illinois), and ground calcium carbonates produced under the trade name DURAMITE®(Imerys, GA).

Titanium dioxide reflects the light well and increases the opacity of compositions for coating. The use of such fogging pigment, such as titanium dioxide, also allows you to choose the color compositions for coating before application to get the desired color of the finished coating. Rutile titanium dioxide is the preferred mud pigment, however, you can use the anatase titanium dioxide and other mud pigments. Suitable titanium dioxides are TIPURE®(DuPont Company, Wilmington, Delaware), TIONA®(Millenium Chemicals, Maryland) and TRONOX®(Tronox Inc., the state of Oklahoma). Suitable titanium dioxides include TIONA®TR-90 and TRONOX®821. Originally monochrome compositions for coating contain generally from about 0 to 20 wt.%, from about 3 to 16% wt. or from about 5 to 12 wt.%. mud pigment (pigment), if they are present. As already noted, additionally, the compositions may contain other nicolardi pigment (pigment) filler/base.

the other components and additives

To improve the dispersion of pigments and/or netoleruoja pigment (pigment) filler/base in compositions for coating sometimes include a dispersing agent. Dispersing agent generally includes a hydrophilic copolymer salt, a hydrophobic copolymer salt and/or polyacidic salt. Suitable dispersing agents are sold under the trade name TAMOL®(Rohm & Haas Company, Pennsylvania). The use of hydrophilic copolymer salts, such as TAMOL®1124, it is preferable for the compositions latex-based. Similarly, hydrophobic copolymer salt is used mainly in the compositions of oil-based.

Also in compositions for coating dispersion dyestuffs and/or netoleruoja pigment (pigment) filler/basics use tripolyphosphate salt and tetracene pyrophosphate. Effective use of such tripolyphosphate salts, such as potassium tripolyphosphate (Innophos, new Jersey).

Compositions for coating can optionally contain other additives, including, but not limited to, biocides, fungicides, humidifiers and other additives, to the extent that they do not compromise the stability of the coloring matter. In other words, the decorative effect provided a composition for grease the cover, adding any additives should be pronounced.

Typically, compositions for coating preferably using a bactericidal or fungicidal additives. Suitable fungicide commercially available under the trade name FUNGITROL®(International Specialty Products, NJ). Humectants include polyhydric alcohols, for example, is not limited to, glycols such as ethylene glycol, diethylene glycol (deg), triethylene glycol, propylene glycol, tetraethylene glycol and polyethylene glycols, which are preferably used in compositions for coating for a more even application. Also glycols give the compositions for coating the frost.

Depending on the particular variant embodiment of the invention, a composition for coating may contain from about 15 to 55 wt.%, from about 20 to 45 wt.%. or from about 25 to 35% wt. water. However, it is preferable to maintain the highest possible level of solids.

The substrate and the application method

Originally monochrome compositions for coating mainly applied to the surface of the substrate using any conventional method of paint application, including, but not limited to, application by brush, roller and spray. Suitable substrates for coating include, but are not ogranichivayutsya, new or existing (pre-mounted) inorganic wall panels, such as gypsum wallboard for interior decoration, exterior decoration, and use of moisture, ready nakryvochnyj plaster mortar, concrete slabs and ceiling panels. Suitable wall panels are manufactured under the trade names FIBEROCK®and SHEETROCK®(United States Gypsum Company, Illinois). Also proposed composition for coating can be applied to other surfaces.

As noted above, for the application of the proposed compositions of the coatings you can use the traditional coating methods such as brush application, roller or spraying. Preferably the coating, because it is relatively quick to apply an even coating. Typically, the thickness of the wet coating coating (thickness wet film, NT), is at least approximately of 0.075 to 0.150 mm (3-6 mils). However, the coating thickness of up to 0.150 mm (60 mil) in the wet state can be applied to the surface of the substrate, avoiding drips or flows in applied and, as a result, in the finished coating.

The proposed composition can be applied using airless paint sprayer. Such a device allows the application of a continuous covered is e, having the minimum thickness of the wet film (NT) from about 0.025 to 0.25 mm (1-10 mils), which gives a dry film thickness (TSP) from about of 0.0125 to 0.125 mm (0.5 to 5 mils). This coating becomes touch dry through the period of time from about 30 minutes to 60 minutes under normal drying conditions (25°C (77°F) and 50%relative humidity). Higher humidity or lower temperatures lead to an increase in drying time. When coating with NT thickness from about 0.025 to 0.25 mm (1-10 mil) (dry film thickness of approximately from of 0.0125 to 0.125 mm (0.5 to 5 mils)) approximately 3.8 l (1 gallon) of the composition provides a floor area of about 18,6-37 m2(200-400 square feet). The area of the coating strongly depends on such factors as the condition of the surface of the substrate, the sputtering method, and the thickness and uniformity of coating.

The essence of the proposed by the present invention initially monochrome compositions for coating can be better revealed with the help of the following examples. While the examples and the preceding descriptions are merely illustrative and do not impose restrictions on various possible embodiments of the invention, which can be used by specialists in this field.
