The invention relates to the field of applying coatings on the basis of liquid glass. Can be used in the manufacture of the art products for the decoration of modern interiors, in floristry and other areas where you want to use beautiful unusual texture.

Known decorative textured coating: "hammer", "moiré", "rime", "crocodile skin", "shagreen" and others. To obtain these coatings are paints containing organic solvents, and as film-forming materials are melamine, pentaftalevyh, nitrocellulose, and other polymers. The texture in these coatings is created by modifying the surface layer of film-forming substance by introducing resourcebrowser additives and other technological techniques. These coatings have a peculiar texture, eye-catching and unusual decorative appearance, but they pollute the atmosphere, as they are made using organic solvents. Recommended formulations for application flammable. Another disadvantage of such coatings is a relatively high price. (see Livshits, M. L., Salkowski B. I. coating materials: the Handbook. - M.: Chemistry, 1982, S. 175-179).

Known water-dispersion paint comprising polyvinyl alcohol, sodium LM is some glass, surface-active agent, titanium dioxide and water, characterized in that it contains as a surfactant OP-4 - polyoxyethylene ether of alkylphenol and an additional structural component silicagel matting additive with a particle size of not more than 10 μm, boric acid and ethyl alcohol (see EN NO. 2145621, C09D 129/04, C09D 1/04, C09D 5/02,, 20.02.2000). In the composition to obtain a coating composed of liquid glass and alcohol additives, as well as in the present invention.

However, the water-dispersed paint, proposed in this patent is difficult to make and allows you to get decorative textured coating to the effect of "flowing water".

The closest technical solution is a composition for decorative and protective coating containing, in mass%: binder mixture 32-51; the pigment of 0.25 to 12.0; antifreeze additive 0,35-2,5; surfactant 0,15-1,5; antiseptic 0.25 to 2.5 and the rest of the mineral filler. According to the authors, chemical resistance than the known level more than 2 times, also increases and its decay resistance. As the binder mixture, the authors propose to use organic components and liquid glass in the ratio of 1:(0,09-0,17). As the organic component is used as a compound selected from the group comprising plasticized vodouisant polymer based on styrene, on the basis of butadiene, based on the Acrylonitrile, based on vinyl chloride, based on vinylidenechloride, based on the isobutylene, on the basis of methyl methacrylate, based on acrylamide, based vinylcarbazole, based on vinylpyrrolidone, on the basis of isoprene and other. As a mineral filler composition contains a material selected from the group comprising expanded perlite sand, Marsala, porous Sands on the basis of slag, gravel clay, sand clay, burnt brick, brick chips, plastic chips, plastic pellets, sludge from paper manufacture, marble, granite, porcelain and others. As the pigment composition contains a substance selected from the group comprising fly ash, red iron oxide, titanium white, zinc white, chalk, crowns lead, crowns zinc, chrome greens, herbs zinc, Berlin blue, ultramarine blue, and organic dyes and other substances. As an antiseptic composition contains a substance selected from the group comprising acid benzoic, oxalic, formic, sodium fluoride, sodium silicofluoride, etc. as surfactant composition contains a substance selected from the group comprising the aqueous dispersion of sodium, potassium, calcium salts of the fatty acid fraction C19-C25, the water dispersion of technical, syntheti the ski, natural waxes, etc. as antifreeze additive, the composition contains a substance selected from the group comprising sodium nitrate, potassium carbonate, sodium chloride, calcium chloride, sodium formate and so on (see EN No. 2055821, C04B 41/61, 09D 5/28, 10.03.1996, prototype).

Thus, in the prototype, as well as in the present invention, in the composition to obtain a coating may include some of the same components: liquid glass, dye, sodium chloride. In General, the compositions are substantially different, with the composition proposed in the prototype, more complex, i.e. has a greater number of components and most importantly, when using the formulations in the prototype, does not form a texture of "flowing water" on the surface.

Object of the invention is to obtain coverage with a new decorative effect of "flowing water", with the use of environmentally friendly materials, reduce the cost composition for coating and the ability to apply a coating on various materials.

This object is achieved in that in the method of applying a decorative textured coatings with compositions based on sodium liquid glass, coated receive by creating three layers, and initially in liquid sodium glass add blue or purple ink 0,15-0,30% (by weight), and then sodium chloride 16-33%, the var who're asked for 1-2 minutes, wait 10-12 minutes, before applying the product, the mixture is stirred for 1 to 7 minutes; the second layer is applied using sodium silicate with a glycerol concentration of 45-55%, and the third coating layer is applied using acrylic lacquer.

To explain how the following image.

Fig.1 - Decorative textured coating obtained on the twig of hazel using compositions with a minimum concentration component (example 1).

Fig.2 - Decorative textured coating obtained on the twig of hazel using compounds with a maximum concentration of component (example 2).

The proposed method allows to obtain coatings with a new decorative effect of "flowing water", i.e. having an unusual appearance, namely coating with elements of type "icicles", created by draining slow and fast enough thickening (hardening) of the proposed structure. The method also allows the use of environmentally friendly materials, has reduced the cost composition for coating and the ability to apply a coating on various materials: plaster, terracotta, aluminum, copper, steel, glass, dried flowers and wood, including bars and rods, used in floristry.

To solve these problems, the proposed method of applying a decorative textured coatings flowing in the Yes." For this purpose it is proposed to use the formulations based on environmentally friendly and relatively inexpensive material - sodium liquid glass (GOST 13078-81) with silicate modulus of 2.8-3.0. Sodium silicate in the proposed composition is film-forming (binder) material. To make color or shade of the coating composition is injected dye. As a dye it is proposed to use ink: blue or purple (THE 2389-036-06916705-02). Decorative textured coating "flowing water" was obtained by creating multiple layers. The proposed method allows application of coatings on various materials: plaster, terracotta, aluminum, copper, steel, linen, rope, glass, chilly color and wood. These coating materials based on liquid glass had a sufficiently high adhesion when using the following technology: surface preparation, first layer of textured coating, drying (curing), apply a second coat of textured coating, drying. If operating conditions water-resistant textured coating is insufficient, then the surface texture of the coating on the basis of liquid glass was applied protective coating with acrylic lacquer AK-199.

Surface preparation consisted of degreasing and executed only when the application of coatings on metal products, with rjasanow surface. Degreasing was performed with white spirit.

The first layer was formed with the following composition, % by weight: sodium chloride 16-33; ink 0,15-0,30 and the rest is sodium silicate. In the liquid glass was added ink and thoroughly mixed until a homogeneous color. Then was gradually added sodium chloride and was constantly stirred for 1-2 minutes, when it was formed translucent jelly-like lumps and the mixture began to thicken. To achieve a consistency suitable for application of the first coating layer, it is necessary after the introduction of sodium chloride to wait 10-12 minutes. Before applying the product mixture is again thoroughly for 1-2 minutes, the resulting mixture becomes dense, homogeneous inclusions, bubbles, and crystals of salt. The resulting composition can be applied to products by methods of irrigation, dipping or molding. When implementing the first two methods, the formation of the necessary marks ("icicles") was completed in 4-5 minutes after application. For the formation of invoice by the method of modeling is necessary to increase the mixing time before applying the mixture with 1-2 minutes to 5-7. The mixture will become thicker and quite ductile. After coating by any of the three methods has received various stains ("icicle") with inclusions of crystals of sodium chloride and bubbles without the ha. The following operation - drying was carried out at room temperature for 12 hours.

The second layer is textured cover was created using a composition consisting of a liquid sodium glass with glycerin brand D-98 (GOST 6824-96) concentration of 45-55% by weight. When introduced into liquid glass glycerine formed a transparent gel-like mixture, which was used for forming the second transparent layer textured coatings methods of dipping or showering. Also this second coating layer can be applied by brush. Within 7-10 minutes after the application has completed the process of forming the coating. If it was required by the conditions of the coating textured coating was applied protective coating with acrylic lacquer AK-199.

Example 1 a specific application of the proposed decorative textured coating on the sample from rod hazel

The proposed coating was applied using the compositions with a minimum concentration component. The first layer was formed with the following composition, % by weight: sodium chloride 16; blue ink 0,15; liquid sodium glass the rest. In the liquid glass was added ink and thoroughly mixed until a homogeneous color. Then was gradually added sodium chloride and was continuously stirred for 1 minute. Then to achieve it is possible to viscosity, suitable for applying the first coating layer, after the introduction of sodium chloride waited 10 minutes. Before applying the product mixture is again thoroughly mixed for 1 minute, the mixture became homogeneous with inclusions of bubbles and salt crystals. The resulting composition was applied using a dipping method. Then ran dry at room temperature for 12 hours. The second layer of textured coatings were created by dipping method using a composition consisting of a liquid sodium glass with glycerin concentration of 45% by weight. After drying at room temperature for 24 hours brush struck a layer of acrylic lacquer AK-199. As can be seen from Fig.1, the coating obtained "flowing water" has a relatively long and thin streaks - "icicles".

Example 2 specific application of the proposed decorative textured coating on the sample from rod hazel

The proposed coating was applied using a composition with a maximum concentration of components. The first layer was formed with the following composition, % by weight: sodium chloride 33; ink 0,30; liquid sodium glass the rest. In the liquid glass was added ink and thoroughly mixed until a homogeneous color. Then was gradually added sodium chloride and was continuously stirred for 2 minutes. Then to achieve the necessary wask the STI, suitable for applying the first coating layer, after the introduction of sodium chloride waited 12 minutes. Before applying the product mixture is again thoroughly mixed for 2 minutes, the mixture became homogeneous with inclusions of bubbles and salt crystals. The resulting composition was applied using a dipping method. Then ran dry at room temperature for 12 hours. The second layer of textured coatings were created by dipping method using a composition consisting of a liquid sodium glass with glycerin concentration of 55% by weight. After drying at room temperature for 24 hours brush struck a layer of acrylic lacquer AK-199.

As can be seen from Fig.2 obtained in example 2, the coating "flowing water" is shorter and thick smudges compared with stains "icicles", obtained in example 1.

Thus, the texture of the coating can be adjusted by varying the concentrations of the components of the proposed structure.

The present invention allows to obtain the following result. Developed a method of applying a decorative textured coating with a new decorative effect of "flowing water". For coating using environmentally friendly materials, with a relatively low cost. The proposed method of applying a decorative textured coating can be applied to the hypoxia materials: plaster, terracotta, aluminum, copper, steel, linen, rope, glass, chilly color and wood, including bars and rods of hazel, used in floristry.

The method of applying a decorative textured coatings with compositions based on sodium liquid glass, characterized in that the coating produced by the creation of three layers, and initially in liquid sodium glass add blue or purple ink 0,15-0,30% (by weight), and then sodium chloride 16-33% (by weight), stirred for 1-2 minutes, wait 10-12 minutes, before applying the product, the mixture is stirred for 1 to 7 minutes, dried first layer 12 hours at room temperature; the second layer is applied, using sodium silicate with a glycerol concentration of 45-55%, dried, a second coat 24 hours at room temperature, and the third coating layer is applied using acrylic lacquer AK-199.
