The invention relates to compositions for coating, namely, polymer paint and varnish materials, particularly to compositions for coating polycarbonate based.

These materials are most successfully can be used to obtain a weather-protective and decorative coatings to surfaces of wood, metal, concrete and other surfaces that are both inside and outside of the premises.

Paint coating based on polycarbonates are characterized by increased light and moisture resistance and low hygroscopicity. They have high mechanical properties, dielectric properties, continuing in a wide temperature range from a very low negative temperatures up to 190-200°C, resistance to acids, oxidizing agents and detergents. Polycarbonate is considered to be physiologically safe polymer due to the lack of biological activity of himself and any of the extracted components (Smirnova O.V., Erofeev D.B Polycarbonates, M.: Chemistry, 1975, 288 S.).

Know the use of the polycarbonates to obtain films and coatings. However, the chemical structure of the aromatic polycarbonates and primarily based on bisphenol a results in a high rigidity of the resulting films and their low adhesion to surfaces upon receiving the safety coatings under normal conditions. Therefore, to increase the adhesion of polycarbonate coverings to substrates using or surface chemical modification of the film, or high-temperature method of creating a polycarbonate coating on the metal surfaces, providing for the mandatory heat the product to a temperature exceeding the melting temperature of the polycarbonate, i.e 260-280° (Schnell, Chemistry and physics of polycarbonates, M.: Chemistry, 1967, 229 S.).

Known composition used to obtain plasticized films based on polycarbonate comprising aromatic polycarbonate, plasticizer - politician (2-50% by weight of polycarbonate) and methylene chloride as solvent [Pat. USA No. 3070563, US C1 524/244 (1962)].

The disadvantage of this arrangement is the need for preliminary synthesis of plasticizer - politician of ethylene oxide and Quaternary alkyl amine, and a long time (24 hours) plasticization of polycarbonate films. The possibility of using this composition to produce a protective coating of various surfaces is not discussed.

Known for highly filled thermoplastic composition comprising aromatic polycarbonate, polyalkyleneglycol resin as a plasticizer, and also pigments and mineral supplements in the form of salts and oxides of metals, which uses the I for the manufacture of products by the method of termextraction (Pat. USA No. 5510398 US C1 523/171 (1996), MCI 09 D 5/29).

However, the composition due to its consistency is not intended to create a decorative and protective coatings on surfaces.

Known polymer composition to form a protective coating on concrete and reinforced concrete structures based on pornstarsexy products - waste furfuralcohol production. As the polymer binder is used epoxygenase resin (30 parts by weight) with polyethylenepolyamine (30 parts by weight) as a hardener, and a flexible nitrile butadiene rubber as a plasticizer and an organic solvent (acetone) [U.S. Pat. Of the Russian Federation No. 2045561, C1 6 C 09 D 171/14 (1991)].

The disadvantage of this arrangement is that at the specified ratio of resin and hardener composition becomes unstable during storage due to the curing process. Therefore, the curing agent is introduced into the composition directly before it can be used to create coverage. The possibility of using this composition for application of protective coatings on various surfaces is not discussed.

The closest major characteristics of the claimed composition is a composition containing 1 parts by weight of polycarbonate, 9 parts by weight of methylene chloride and 10 parts by weight of diethylphthalate as a plasticizer [Japan Patent No. 21146, NAT. CL 24 N 21 (1965), RICH. 16 779 P. (1967)]is selected in which the quality of the prototype. It is a primer composition, since it is used only for preliminary liquid primer for metal surfaces. Protective polycarbonate coated with a high adhesion to metal is created in the second stage by spraying to primed surface powdery polycarbonate and subsequent baking it at 240-350°C.

The disadvantage of this composition is its limited application only for the purpose of priming the surface, as formed from the coating does not have adhesion to any material. Another disadvantage is the complexity of the hardening polycarbonate coating on the second stage of its formation and high-energy process. The composition cannot be used to obtain quick-drying coatings on other common, but less resistant building materials in the usual way of drawing. Therefore, its use is limited to the creation of coatings only the two-stage method of high-temperature powder technologies, and the need for painted surfaces should be used-resistant dyes, small.

The present invention is the creation of a quick-drying in natural conditions the polymer paint composition on the basis of aromatic polycarbonate, to the which allows you to get in one stage, randomly colored coatings on various building materials without compromising adhesion by applying a composition in the usual way, followed by short drying its on the air. Furthermore, the obtained coatings have high weather resistance combined with good decorative properties and high adhesion to wood, metal, concrete, asbestos cement Board, and other building materials in a wide temperature range and, thus, the claimed composition can be successfully used to create internal and external protective and decorative coatings.

This object is achieved in that the polymer paint composition comprising an aromatic polycarbonate, a plasticizer and a chlorinated aliphatic solvent, and as an aromatic polycarbonate contains a polycarbonate based on bisphenol a with a molecular mass of 26000-36000, as a plasticizer contains a copolymer of Acrylonitrile-butadiene-styrene, and further comprises a polymeric adhesive, mineral filler selected from the group of fine mineral material: aluminum powder, titanium dioxide, salts of alkaline-earth metals, talc, micropollutant; dye, chosen from a number of phtalocyanine dyes or colored mineral pigments, and polyoxyethylenesorbitan (tween 80) as the surface-the active substance in the following ratio of components, parts by weight:

As a polymeric adhesive composition contains epoxygenase resin ED-20 or ED-22 (GOST 10587 76) with hardener polyethylenepolyamine (TU 6-02-594-80) in a mass ratio of 100:7 (by mass).

Composition as a polymer adhesive contains a polyvinyl acetate (GOST 18992-80) or universal polymer adhesive based on polyvinyl acetate resin with the trademark "NACET-S" (Producer - Poland) with the content of the polymeric binder 37 wt.%.

As the high molecular weight plasticizer is used a copolymer of Acrylonitrile-butadiene-styrene (ABS polymer), THE 6-05-1587-84.

As a fine mineral filler: titanium dioxide (GOST 19808-84), barium sulfate, calcium carbonate, talc, with sizes of dispersed particles of 30 nm, and (or) micropollutant (MB-10-94, CJSC "GEOKOM is, RF) with a maximum particle size of 100 nm, and (or) aluminum powder (GOST 5494-95).

As the dyes used phthalocyanine dyes (blue 1510 and green G-7, Jayscolor GFP, China) or colored mineral pigments: yellow lightfastness (Jayscolor Y01, China), pigment orange (Jayscolor OR 05, China), iron oxide pigments (GOST 18172-80 or THE 6-10-602-86).

As surface-active substances are used polyoxyethylenesorbitan (tween-80 "FERAK" FRG).

As the solvent used chloroform or a mixture of methylene chloride in any proportions.

A significant difference between the claimed polymer paint composition from the prototype is that it contains a polymer adhesive, which gives it a high adhesion to a variety of construction materials; as a plasticizer, it contains a copolymer of Acrylonitrile-butadiene-styrene, and optionally a mineral filler, a colorant and a surfactant, which meets the criterion of novelty.

The composition is prepared by successively mixing the components and then applying it to the surface by any known method: by air spraying, irrigation method, dipping, using a paint roller or brush. If necessary, reduce the viscosity of the composition can complement what Ino dilute chlorinated aliphatic solvent. Before applying the composition on the steel surface after the last regular cleaning and degreasing was treated with phosphate cleaner rust "NEFOS (TU 21490072 - 00203938 - 2001), OJSC "APATIT". Curing of the composition with the formation of a solid coating occurs during drying of the applied layer on the air in vivo in 15-20 minutes

Viscosity of the proposed composition was determined on the viscometer B3-246 with the nozzle diameter of 4 mm at a temperature of 20±0,5° (GOST 8420-74).

Opacity is expressed in the number of grams of material required to cover an area of 1 m2.

The adhesion of the coating was determined by the method of lattice cuts in the points at 24 h after application of the composition on the tested surface.

The specific formulations of the claimed compositions and method of their preparation are given in the following examples and table.

Example 1. In the mixer pour 77 g of chloroform and poured with stirring 13 g of aromatic polycarbonate; stirring is continued for several hours until complete dissolution of the specified polycarbonate at room temperature or within half an hour of heated solution. Then thereto was added with stirring 2,60 g epoxygenase resin and of 0.182 g polyethylenepolyamine as hardener (which corresponds to a mass ratio of 100:7). the resulting solution under stirring was added 0.005 g of tween-80 and 0.65 g of a copolymer of Acrylonitrile-butadiene-styrene, 6 g of chloroform. Separately triturated phtalocyanine dye 0.65 g, titanium dioxide 1,3 g and barium sulfate 0.65 g, the mixture is diluted with 3.5 g of a solvent and applied to the polymer composition under stirring for 5-10 min, after which the resulting product is poured into a tightly sealable container. To obtain the coating composition is applied to the surface in any way. Curing of the coating occurs by natural drying in the air for 15-20 minutes.

Example 2. According to the method described in example 1 to prepare a solution of 13 g of aromatic polycarbonate in a mixture of 30.0 g of chloroform and 30.0 g of methylene chloride. Separately prepare a solution of 3.9 g of polyvinyl acetate in 16.0 g of chloroform and injected into the solution of the aromatic polycarbonate. To the obtained solution under stirring was added 0.005 g of tween-80 and 0.39 g of a copolymer of Acrylonitrile-butadiene-styrene, 3 g of chloroform. Further according to the method described in example 1, administered 1.0 g TiO2, 10.0 g of micropollutant and 0.3 g of pigment yellow lightfastness of 3.0 g of chloroform and stirred for further 10 minutes

Example 3. According to the method described in example 1 to prepare a solution of 12 g of aromatic polycarbonate in 70 g of chloroform. Separately with stirring 4.0 g glue "NACET-S"containing 1.5 g of polyvinylacetate, diluted with 8 g of chloroform and injected in a solution of a specified polycarbonate. To the obtained solution at peremeci the years added 0.001 g of tween-80 and 0.12 g of a copolymer of Acrylonitrile-butadiene-styrene 3.0 g of chloroform. With continued stirring, 0.6 g of the aluminum powder and 0.1 g blue phthalocyaninato dye, mix 5 minutes

In examples 7, 8, 9, the characteristic of the compositions obtained outside of the claimed composition, from which it is clear that changing the ratio of components beyond that impair the technological properties of the composition due to changes in optimal viscosity and reduces the quality of the applied coating by reducing the magnitude of adhesion and deterioration of the coverage.

In example 9 increased the number of polyethylenepolyamine in relation to epoxygenase resin to 10:100 (parts by weight) of the composition is unstable during storage, because after 15-20 days, a gel is formed due to intensive curing epoxygenase resin in the presence of excess hardener. This gel surface composition, violating its technological properties and makes it unusable.

The inventive composition allows to obtain fast drying in natural white or dyed in any color coverage in just one stage, by applying the usual methods with subsequent drying in air for 15-20 minutes Coatings have high adhesion to the surface of most building materials compared to the prototype. Used the e claimed composition can significantly simplify technology for the production of colored coatings, to reduce energy consumption and increase efficiency of production. The proposed composition is stable in hermetic storage conditions for at least one year without changing technological properties.

Testing of coatings applied to steel, concrete, slate (composition 4) and on steel, concrete, slate, wood surface (composition 5), carried out after exposure of samples in the natural climatic conditions in the course of 1.5 years, including two winters. The results showed that the coatings have a long (>1.5 years) resistance to weathering and climatic temperature changes, combined with a good decorative properties. Therefore, the proposed polymer paint composition can be used to create internal and external protective and decorative coatings.

Thus, the claimed polymer paint composition exceeds the prototype over a wide range of its practical use and allows you to get coverage on all construction materials without restriction on their heat resistance and more accessible and widely accepted methods of application. The proposed composition is stable when stored in airtight conditions for at least one year without changing technological properties.
