ANTICORROSION PAINTWORK COMPOUND Russian patent published in 2001 - IPC

FIELD: preparation of mono-and multiplier coatings, such as primers, enamels for protection of steel structures, products and equipment operating under conditions of intensive atmospheric effects against corrosion in industrial and civil engineering, in engineering structures and water-development projects operating under higher humidity conditions and industrial and power plants, equipment for chemical and petrochemical industries, port facilities ship building, and motor industry. SUBSTANCE: claimed paintwork compound comprises polyurethane lacquer, highly dispersed zinc powder prepared by evaporating metallic zinc in neutral gas atmosphere followed by condensation thereof, rheological additive and organic solvent, ratios of components being as follows, wt %: polyurethane lacquer 13.6- 24.4; said highly dispersed zinc powder, 71.1-79.5; rheological additive, 0.3-0.5; and organic solvent, the balance. Rheological additive includes microtalc for paint and varnish industry and/or benton SD or modified castor oil. Invention makes is possible to prepare single-packing paintwork compound with prolonged storage period without irreversible changes in properties. Said compound has high anticorrosion and chemical resistance of surface being treated in aggressive media at elevated temperatures. EFFECT: higher mechanical and adhesion properties of the paintwork compound. 5 cl, 2 tbl _
