A characteristic feature of the composition is increased resistance to the effects of factors of temperate climate 3 at a temperature 20-2aboutWith 1 hClosest to the invention is a composition containing polystyrene, coal tar, aluminum powder and solvent [2]
The disadvantage is the low mechanical strength and surface quality.An object of the invention is the improvement of performance characteristics of the coating.The problem is solved in that the composition for protective and decorative coatings, including polystyrene, coal tar, aluminum powder and solvent that contains components in the following ratio, wt.

Modification of polystyrene with coal tar in the environment of the solvent in the selected range of source material in the formulation composition has an influence on the physico-mechanical characteristics of the coating, reliably providing technological properties: thixotropy, aggregate stability of the molecular structure and adhesion in cold drying.The copolymerization reaction takes place in the interaction of coal tar with polystyrene in a solvent environment containing labile hydrogen atoms, hydrocarbon, which cuts off the polymer chain, the AI. Due to the presence of double bonds, formed a cross-linked polymer structure copolymerization, which give the coating of high hardness and increase chemical resistance.A colloidal solution of coal tar and polystyrene in a solvent selected concentration is optimal dispersion medium, excluding additive surfactants. Coal tar contains polar groups (naphthenic acids, their salts, products of sulfonation), separated by large non-polar hydrocarbon chains, which leads to their surface-active properties.Due to means of the polystyrene to the surface of aluminum and its good wetting of the binder in an optimized quantitative ratio of the components is provided a stable dispersion and floating particles of the aluminum powder in the coating layer, where they are parallel to the painted surface with a partial overlap, the so-called "listomania". This provides high reflectivity, temperature resistant coating, its gas and dial: - nichebot, corrosion and weather resistance, mechanical strength of the frame structure of the coating.The composition is prepared with the-05-1901-81. Produce stirring for 2 h at a temperature of 50-60aboutC. Stand the mixture for 2-4 h until complete dissolution. Next, load the coal tar, OST 1462-80. The components are stirred for 2 hours Then injected aluminum powder, GOST 5494-A part with thorough stirring. The composition is applied at ambient temperature (-5.+35aboutWith brush in 3-4 layers. The thickness of each layer of 30-35 microns. Dry each layer for 20-30 min at room temperature. The finished coating can withstand up to commissioning of not less than 24 hours Consumption composition (opacity) 140 g/m2.For validation of the performance characteristics of the coating was prepared with the number of compositions of different formulations and comparative testing of physico-chemical and performance properties of the compositions and coatings, the most characteristic of which are presented in table. 1 and 2.Quantitative evaluation was carried out according to the established procedure the following parameters: the viscosity of the composition, drying time, thixotropy, appearance, gloss, elasticity, strength and hardness of the film, adhesion to steel and concrete, the resistance of the coating to aggressive environments and light - and temperature resistant.As can be seen from the table.2, a set of kapotasana and the drying time of the coating in the range of reasonable sufficiency 4 h at room temperature. Strength, resistance to various environments, thermal stability, thixotropy of the coating increased while maintaining the values of indicators such as elasticity, adhesion to steel and concrete, light-fastness.The numerical values of the parameters of intended use of the coating and physico-chemical properties of the composition are summarized in table.2.When the content of polystyrene in the composition is less than 10 wt. reduced heat resistance, electrical insulating properties, film formation, opacity. When the content of polystyrene in the composition is greater than 18 wt. reduced corrosion resistance of the coating.When the content of coal tar in the composition of less than 6 wt. increased brittleness, corrosion, weather and chemical resistance, when the content is more than 10 wt. increased drying time.When the content of aluminum powder in the composition is less than 12 wt. reduced resistance, hiding power, thixotropy, unstable structuring composition. When the content of more than 16 wt. increase the fragility of the coating and the viscosity of the composition.The content of the solvent, i.e., the mass ratio of the hydrocarbon components sufficient for complete solvent and providing the selected technological viscosity.

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.
