The present invention relates to coating and filler materials based on epoxy resins which have improved elasticity, weather resistance, compressive strength and chemical resistance.

Epoxy coating and filler materials are well known and used in industry and everyday life as a protective and decorative coatings for steel, aluminum, galvanized, wood and concrete maintenance, marine, construction, architecture, aviation, and when finishing the products. As the main raw material in the preparation of coatings are typically used (a) epoxy resin, (b) a curing agent and (C) a pigment or filler.

Known filler and coating materials based on epoxy resins in addition to the epoxy resin, hardener and pigment/filler often include a number of additional components, such as inert and active diluents, including mono - and diepoxide, plasticizer, bitumen and asphalt fill hibitory corrosion, ultraviolet stabilizers, catalysts and rheological modifiers. As the resin, and curing component can also contain volatile organic solvents, the main function of which is to reduce the viscosity and obtain a consistency suitable for Trevoga be applied using conventional air, airless and electrostatic equipment.

Epoxy protective coatings have a number of properties that make them attractive as coating materials. They are affordable and easy to apply various methods, including truevue spraying, rolling and handling of the brush. Cover well stick to steel, concrete and other substrates are characterized by low penetration of moisture vapour and act as barriers to water, chloride and sulphate ions, provide excellent protection against corrosion under different atmospheric effects and good chemical resistance against many chemicals and solvents.

Materials based on epoxy resins are also used as filler, mainly for work on concrete. In part one of marketable filler materials based on epochs the major silica sand filler as the third component. The material can be applied by struever way and has excellent strength in compression, tension and bending, good toughness and resistance to abrasion and resistance to a wide range of different chemicals and solvents.

Epoxy filler and coating materials generally have low resistance to weathering by sunlight. Although such coatings are chemical and corrosion resistance, irradiation with ultraviolet component of sunlight is accompanied by destruction of the surface, the so-called chalking, which change as the luster and color of the original coating. When required or desirable to retain color and gloss coating, epoxy protective coating is usually on top put more weather-resistant coating, for example, vinyl or aliphatic polyurethane coating. The result is applied to two or sometimes three layers of coatings that provide corrosion resistance and weather resistance. However, the use of such a system is expensive and labor is expensive.

Thus, although the coating and filler materials based on epoxy resin obtained cherokeecasino color and gloss durability, more high corrosion and chemical resistance and superior resistance to mechanical overload. New epoxy coating and filler materials shall meet the requirements of new legislation in relation to the environment and harm to human health. Required epoxy coating and filler materials with improved color stability and durable gloss in sunlight. Desirable epoxy coatings, which do not undergo melenija and do not require a weather-resistant outer coating. Cover and filler materials with superior chemical, corrosion, impact resistance and abrasion resistance required for the primary and secondary chemical enclosing structures, to protect steel and concrete in the chemical industry, energy, rolling stock railway structure, when the wastewater treatment in the pulp and paper industry. Improved epoxy filler materials required for industrial areas, such as shipbuilding and repair docks, where there may be significant shock loads for floors, which periodically needs to be cleaned with steam and aggressive chemicals, such as solstice, acid and highly active chemicals.

Before epoxy coating superior weather resistance was obtained by modification of acrylic resin or by curing inherently weather-resistant epoxy resins, for example, sorbitol glycidyloxy ethers, hydrogenated reaction products of bisphenol a and epichlorohydrin, recently satelitarnych melamine resins with functional epoxy groups from the company Monsanto polyamide resins, resins based on cycloaliphatic amine or acrylic resins with carboxyl functionality or polyester resins. In another case, use epoxydecane polyester resin in combination with defined media with carboxyl functional groups. Although these coatings exhibit higher weather resistance, chemical and corrosion resistance is generally lower than that of the previously described coatings based on epoxy resins.

Epoxy filler materials superior chemical resistance obtained from epoxidizing of novolak and modified cycloaliphatic and aromatic amine curing agents. Filler materials based on epoxidizing but the tee. Aromatic amine hardeners, for example, methylenedianiline and diethyltoluenediamine or contribute to the appearance of lesions or suspected the possibility of their occurrence. These materials usually have excellent chemical resistance, however, their resistance is very low. Discoloration can often occur indoors.

Therefore, the aim of the present invention to provide coatings based on modified epoxy resins with superior chemical, corrosion and weather resistance.

Such non-aromatic hydrogenated epoxy resins are preferred because of their limited reaction, approximately equal to 2, which promotiom the formation of linear epoxy polymer and prevents the formation of crosslinked epoxy polymer. Suppose that the resulting linear epoxy polymer by adding the hardener to the epoxy resin determines the high resistance of the present composition to atmospheric influences. Such non-aromatic epoxy resin to obtain resistant to weather protective cover has never been used because of their limited reactivity and, therefore, the alleged inability of the resin to be cured with the formation of a protective coating.

Each R2selected from the group consisting of hydrogen and alkyl and aryl group with the number of carbon atoms up to six. Preferably, when R1and R2include radicals containing less than six carbon atoms, in order to accelerate the hydrolysis of the polysiloxane, and this reaction is determined by the volatility of the alcohol analogue of hydrolysis. R1and R2radicals with more than six atoms, impair hydrolysis of the polysiloxane due to the relatively low volatility of each alcoholic counterpart. For the preparation of compositions for coating and filler of the present invention the preferred polysiloxane with methoxy, ethoxy and silanol functions, with n chosen so that the molecular is produced, molecular weight less than 400, receive formulations for coatings and fillers, which are brittle and have low impact strength.

R4independently selected from the group comprising alkyl, hydroxyalkyl, alkoxyalkyl and hydroxyacetanilide radicals with carbon atoms to six. Preferably, R4included radicals with the number of carbon atoms up to six, in order to facilitate the rapid hydrolysis of organoalkoxysilanes, and this reaction is carried out by evaporation of the alcohol analogue of the product of hydrolysis. R4having more than six carbon atoms, affects the hydrolysis of organochlorine because of the relatively low volatility of each alcohol equivalent.

Particularly preferred organoalkoxysilanes, such as tralkoxydim A-163 (methyltrimethoxysilane), A-162, a-137 Union carbide, and Z6070 and 26124 Dow Corning.

At least 0.7 equivalent of ptx2">

Preferred aminosilane include bifunctional aminopropyltrimethoxysilane and aminopropyltriethoxysilane. The most preferred aminosilanes in compositions for coating of the present invention is a company Union carbide. Bifunctional aminosilane preferred because such aminosilane has reactivity equal to two, i.e. it has only two hydrogen atoms in Amina, which react with a non-aromatic epoxy resin having reactivity equal to two, which determines the formation of seamless epoxy polymer which possesses better resistance to the action of the atmosphere.

Such amines and aminosilane preferred because they contribute to the formation of compositions for coating with excellent weather resistance as in the sense of stability of color and in terms of preserving Shine. Preferred compositions for coatings contain 10%-20% wt. amine and/or aminosilane. In the case where the composition for coating contains amine or aminosilane in amounts outside the specified range, the composition of the coating will have the worst weather resistance and chemical resistance. A particularly preferred composition for coatings containing about 1 the VA for concrete includes polyamine, partly or completely replaced by aminosilanes, which includes aliphatic amines, metrobidazole, diethyltoluenediamine, medienmitteilungen, methylenecyclopropanes.

Particularly preferred aminosilanes for chemically resistant filler compositions is Z6020 company of Dow cornin (aminoethylaminomethyl). The preferred filler composition includes 2% - 5% wt. polyamine or aminosilane. If the composition for putty contains polyamine and aminosilane is outside the specified limits, in this case, the receiving part having poorer resistance to weathering and chemical resistance. A particularly preferred composition for filling includes about 4% wt. polyamine and aminosilane.

Accordingly, the preferred composition for coatings according to the present izobretenij for putty contains the same components in wt. a ratio of about 3:4. In addition, the ratio of wt. amine and/or aminosilane to organosiloxane in the preferred coating is approximately 3: 1. The preferred composition for putty may include polyamine and/or aminosilane and organooxygen wt. a ratio of approximately 6:1.

In compositions for coating and filler on the basis of the modified epoxy resin of the present invention the ratio of the curing component to solastalgia component can vary over a wide range, regardless of selected whether the hardener from the General class of amines, or aminosilanes General formula given above, or any combination thereof. Usually the component containing the epoxy resin, utverjdayut when a sufficient amount of curing agent, at least from about 0.7 to about 1.2 wt. equivalent of amine to 1 wt. equivalent of epoxy resin or at least to 0.2 moles of aminosilane per equivalent weight of epoxide. If the added amount of the curing agent is less than 0.7 wt. the amine equivalent to EQ. the weight of the epoxide prepared composition for coating and filler will be very slow to cure and to have poor weather resistance and chemical resistance. If if the imago composition for coating and filler will be cloudy or oily.

As for the pigment or the filling component, the present invention offers two main options, depending on whether the composition for coatings or putties.

In accordance with the first variant of the modified epoxy composition of the present invention is applied using conventional air, airless and electrostatic Trevoga equipment, brush or roller and is intended as protective coatings for steel, galvanizirovali, aluminum, concrete and other materials with dry film thickness ranging from 25 μm to about two millimeters. Accordingly, the pigment or filler is a material in the form of particles of fine grinding, preferably 90% are greater than 325 mesh. granulometric scale USA (0,044 mm) and is selected from organic or inorganic colored pigments, including titanium dioxide, black soot, lamp black, zinc oxide, natural and synthetic red, yellow, brown and black iron oxides, toluidine and baseliney yellow, phthalocyanine blue and green, carbazole violet, and fillers, including powdered or crystalline silica, sulfate, bar the cat, gypsum, feldspar and the like.

The preferred composition for coating includes up to 50% wt. finely dispersed filler particles. In cases where you want a transparent covering composition, it may not contain pigment or filling component. Transparent coating compositions can be used as a decorative coating or sealed cover filler in the composition. If covering the compositions contain less than 10% wt. fine filler, the raw material cost is usually too high and the resulting composition for coating has a very low opacity, i.e. it does not cover the substrate in a single layer. If the covering composition contains more than 50 wt.%. fine filler, the resulting composition is very tough to apply. A particularly preferred composition for coating contains about 20% wt. fine filler.

The pigments or fillers are usually added to part epoxy zolosoderzhashchikh component and dispersed in the mixer prior to milling degree on Hegman at least 3 or in a ball or sand mill to the same milling degree before adding polysiloxane and organoalkoxysilanes components. Selection Tawney 3, allows you to atomize the mixture zolosoderzhashchikh and curing components using existing equipment for applying a jet of air, airless and electrostatic methods.

In accordance with another variant of the present invention modified epoxies are used for the preparation of filler materials, pigments and fillers include a mixture of large and small particles. At least about 85%-95% wt. the pigment component or filler has a size of 10-200 mesh. (2,00-0,074 mm) grain-scale U.S. (major) and about 5%-15% wt. filler are larger than 325 mesh. (0,044 mm) (small). The range of sizes of filler provides better packing efficiency and optimizes the content of cheap filler in the composition. The combination of small and large filler provides better compressive strength filler material.

The preferred coarse fillers are aluminum oxide, garnet, pumice and silica sand. Preferred finely dispersed fillers include those materials listed in the first embodiment of the present invention. The preferred filler composition ASD raw materials is too high, and composition for putty will have a low compressive strength. If the composition of the filler composition contains more than 90 wt.%. filler, its viscosity will be too high for the application. Especially preferred filler composition with a filler content of about 70 wt.%

The pigment particles of large size or a filler may be mixed with solostaran component, forming dvuhaktnoy packing or Packed as a separate third component or zachariasse in any combination. Modified epoxy filler materials of the present invention is typically applied with a layer thickness of 1.5-13 mm (0.06 to 0.50 inches), using a roller, trowel or sieve.

Water is an important ingredient of the present invention and must be present in a quantity sufficient for the occurrence of hydrolysis of organoalkoxysilanes and/or polysiloxane and the subsequent condensation. Sources of water are mainly atmospheric humidity and adsorbed moisture on the pigment or filler. You can add an additional amount of water to speed up the curing, which depends on the surrounding conditions, for example, using cover and filler compositions in arid is the resource of water. Cover and filler compositions prepared without the addition of water, may contain an insufficient amount of water for the reactions of hydrolysis and condensation, and then you can get trains to inadequate UV resistance, corrosion and chemicals. Cover and filler compositions containing more than about 2 wt.%, hydrolyzed and polymerized with undesirable gel formation before use. Particularly preferred covering and filler composition from about one percent water content.

If necessary, water may be added either epoxy resin or polienovy hardener. Other water sources may contain trace amounts and include epoxy resin, polienovy hardener, thinning solvent and other ingredients. Water may also be included in the application of ketimines or spirtovanny mixtures as described in U.S. patent N 4250074 included as references. Regardless of the source of the full amount of water in a particularly preferred composition for coating and filler should be required for stoichiometric reaction of hydrolysis. Excess water is undesirable, as this smart is taken to solastalgia component or as a completely individual component to accelerate drying and curing modified epoxy covering and filler materials of the present invention.

Used catalysts include metal driers are widely used in the dyeing industry, for example, zinc, manganese, cobalt, iron, lead and tin, each in the form of octoates, neodecanoato and napthanate. Acceptable catalysts include ORGANOTIN compounds of General formula

To accelerate hydrolytic polycondensation of the polysiloxane and the silane can be used dibutil avodart, dibutil lovedeath, organic tenancy, sodium acetate and aliphatic secondary and tertiary polyamine, including Propylamine, ethylaminoethanol, triethanolamine, triethylamine, and methyldiethanolamine. These compounds can be used as individual substances or in mixtures. The preferred catalyst is dibutyltindilaurate.

Modified epoxy coating according to the present invention typically have low viscosity and can nanosims is Ksenia spray when using electrostatic Trevoga equipment or to improve the fluidity and smoothness and appearance when applied with a brush, the roller or with the use of conventional air or airless equipment. Examples of solvents include esters, ethers, alcohols, ketones, glycols, and the like compounds. The maximum amount of solvent that is added to cover or filler composition of the present invention, is limited in accordance with the legislative act of regulation of the purity of the ambient air of approximately 420 grams of solvent per liter of the composition for coating and filler.

The preferred composition for coatings and fillers may include such modifiers and substance in an amount up to 10 wt.%

Epoxy-polysiloxane composition for coatings according to the present invention comes in the form of a system of two packaging in moisture-proof containers. One package contains the necessary the solvent. The second package contains polyamine

and/or aminosilane and arbitrarily catalysts or accelerating agents.

Epoxy-polysiloxane composition for putty of the present invention typically comes in three packages, in water-proof containers. The first package includes epoxy resin, polysiloxane, organooxygen, colored pigments and additives. The second package contains polienovy and/or aminosilane hardeners and optionally catalysts. In the third package contains coarse and fine pigment particles and fillers.

Epoxy-polysiloxane composition for coating and filler of the present invention can be applied at ambient temperature in the range -6oC - 50oC. At temperatures below minus 18oC curing slows significantly. However, the composition for coating and filler of the present invention can apply to be subjected to heat treatment at temperatures up to 150-200oC.

Without intending to limit myself to any theory, we assume that the curing modified epoxy resin composition for coating and filler of the present invention includes simultaneously Pho epoxy polymer and hydrolytic polycondensation of polysiloxane and organoalkoxysilanes with obtaining alcohol and polysiloxane polymer. When aminosilane used for preparation of the curing component, the amino aminosilane reacts connection and silane group aminosilane is subjected to hydrolytic polycondensation. In dry condition modified epoxies for coatings and fillers of the present invention are in the form of epoxidations polysiloxane, which has a significant advantage compared to standard epoxy systems.

In the preferred composition for coating an aromatic epoxy resin is reacted with bifunctional aminosilanes, forming a linear epoxy polymer by getting in linear city cycloaliphatic/aliphatic epoxy polymer with side alkoxysilane groups.

I believe that in isolation the reaction of epoxy resin and polyamine education utverzhdenii epoxy resin takes place as follows:

The hydrogens of the secondary amine can also react in the following way:

< / BR>
I believe that the reaction of hydrolytic polycondensation organoalkoxysilanes and polysiloxanes of the present invention proceed in several stages. In the first article the groups, proceeding in the presence of water and catalyst with the formation of the corresponding silanols and selection of alcohol, as illustrated in reaction 1.

Reaction 1

Hydrolysis of organoalkoxysilanes, i.e. dialkoxybenzene

< / BR>
and/or

Hydrolysis of the polysiloxane with CNS functional groups

< / BR>
The second reaction involves the condensation of silanols obtained by hydrolysis of organochlorine and polysiloxane, that is, dialkoxybenzene and polysiloxane with CNS functions, to obtain the polysiloxane and water.

The reaction of 2

Condensation of silanol

< / BR>
The rate of both reactions are highly dependent on pH, but under optimal conditions, the hydrolysis and condensation starts in a few minutes. The same factors, which accelerate the hydrolysis of alkoxysilanes and condensation silanols also accelerate the condensation of silanol and polysiloxane precursor with metaxylene functional groups. The full scheme of hydrolysis and complete condensation of organochlorine and polysiloxane complex. The drawing shows a model of the hydrolysis of dialkoxybenzene and condensation derived from Huls Corporation Silicon Compounds Register and Review.

Silanol obtained by hydrolysis of alkoxysilane, that is in or fillers, for example, ground glass, quartz, silica. The same silanol can also condense with the hydroxyl groups obtained by the reaction of epoxy resin and polyamine.

In the end, the chemical and physical properties epoxypropoxy materials for coating and filler of the present invention are determined by the correct choice of epoxy resin, organoalkoxysilanes, polysiloxane, polyamine or aminosilane hardener and pigment or filler, as well as the relative speed of reaction of epoxy resin with hardener and hydrolytic polycondensation of organochlorine and polysiloxane.

Composition for coatings prepared by combining bifunctional aminosilane with non-aromatic epoxy resin, has a high resistance to alkali, to atmospheric influences, allows multiple coating has a high abrasion resistance than polyurethane (which is completely unpredictable, since the siloxane polymers and epoxy polymers have poor resistance to abrasion).

Compositions for coating and filler of the present invention is able to achieve full curing at a temperature of arrojadoa invention can achieve full curing process heat at temperatures up to 150 - 200oC.

The compositions according to the present invention for coating and filler demonstrate an unexpected and surprising improvement in the resistance to chemical corrosion and weathering, as well as high compressive strength and elongation, excellent resistance to impact and abrasion.

Solastalgia mixtures of examples 1, 2 and 3 and comparative example 4 was mixed with hardeners and solvents shown in table 3, and were applied to the subjects of the panel in the same way.

Epoxypropoxy composition for coatings prepared in accordance with table 3, tested at the time of curing, atmosferoustojchivosti, resistance against corrosion and chemical resistance. Tests conducted by the ASTM and in accordance with industrial methods:

1. ASTM C53, sometimes referred to QUV accelerated destruction under the influence of atmospheric influences, is an accelerated test on modeling the deterioration of the coating under the action of sunlight and water, rain, or dew. The subjects of the panel was subjected to PoO the formation of bubbles in the coating.

2. ASTM B defines the criteria corrosion resistance of the coated panels exposed to salt stream (fog) under previously described conditions. The panel was periodically subject to inspection and was determined by the formation of blisters and rust in accordance with ASTM D1654. The impact assessment was conducted on a ten-point scale, where 10 corresponds to no change.

3. Chemical resistance, method C-117, Union carbide was determined by the resistance of coatings to ten different reagents. One ml of each reagent was placed on the test floor and was covered with watch glass. After 24 hours, the reagents were removed and any changes were evaluated on a scale from 1 to 10, with 10 indicates no change, 8 - some changes, 6 - significant changes, 4 - partial destruction and 2 - complete destruction.

The gloss retention when conducting QUV accelerated tests on the effects of atmospheric environment, tests on the effects of salt fog tests on chemical stain has clearly shown that epoxypropoxy compositions for coatings of the present invention possess superior chemical, corrosion and weather resistance in comparison with the known epoxy sostava according to the present invention using it as a filler. Filler compositions prepared from the ingredients and in the proportions in grams shown in table 4. Each composition for putty was prepared by adding the ingredients in the pot 1,14 l (one quart) and mixing with a stirrer, Jiffy until smooth. Each composition for putty was applied with a spatula on a steel plate of a thickness of 3.2 mm (1/8 inch) 102 x 305 mm, cleaned, sandblasted, for chemical spot test, and impact strength. Samples for testing tensile, bending and compression molded in the appropriate ASTM standard form. The tests were carried out after 7 days curing at 20oC and 50% relative humidity. Chemical resistance was determined by the method C117 Union carbide. Tests for the measurement of compressive strength, tensile, Flexural and impact was performed according to ASTM methods:

1. ASTM G14 to determine the energy required to fracture the samples for filler, and measuring the ability to withstand mechanical destructive influence at work.

2. ASTM C-307 tensile strength, ASTM C-579 tensile and compression ASTM C-580 Flexural strength. Tests are designed to measure the degree of cure, the ability to carry a load and maximum eg what's compositions.

Example 6A is similar to example 6, except that the epoxy resin was dried over molecular sieves 4 within 24 hours and the mixture of the pigment/filler was kept for 48 hours at a temperature of 110oC, then spontaneously cooled overnight in a desiccator at 20oC and 0% humidity. Dried epoxy resin, polysiloxane, organosilane, protivovospalitel, aminosilane and dried mixture of pigment and filler were mixed for 2 minutes in the mixer, Jiffy and spread it on the steel plate. Coated plate was then placed in a desiccator at 20oC and zero relative humidity and utverjdali. After 36 hours the sample according to example 6A was sticky compared to the sample in example 6, which was Tegoshi. After 7 days at 20oC and 0% humidity chemical resistance of the sample according to example 6A was worse than that of the sample according to example 6. This illustrates the importance of the presence of water in epoxypropoxy of the present invention.

Durable compression samples according to examples 5 and 6 and comparative examples 8 and 9 was immersed for 7 days in 50% caustic soda 98% sulfuric acid and the methyl ethyl ketone. Samples were removed from the subjects of liquid media was rinsed with water and dried within 48 hours Prosti compression in all three of the tested liquid environments. The sample of comparative example 8 has retained more than 90% of the initial compressive strength of 50% caustic soda, however, the samples were completely destroyed in 98% sulfuric acid or methyl ethyl ketone. The sample in comparative example 9 has retained 92% and 80% of the initial compressive strength of 50% caustic soda and IEC, respectively, but in 98% sulfuric acid is completely destroyed.

Examples 5-9 clearly demonstrate that the compositions for the filler of the present invention have improved chemical resistance, higher compressive strength and shock in comparison with known materials based on epoxy resin.
