ENAMEL Russian patent published in 2007 - IPC C09D127/06 C09D5/28 

FIELD: paint and varnish materials.

SUBSTANCE: invention relates to preparing paint and varnish compositions (enamels). The proposed enamel comprises a film-forming component consisting of a mixture of waste from manufacturing copolymers of vinyl chloride with vinyl acetate and vinyl chloride with vinylidene chloride formed in process of cleansing equipment in their ratio, mas. p. p.: (1.7-3.2):(10.3-14.6); organic solvent, vat residue in synthesis of vinyl chloride with the content of dichloroethane 74.20 mas. p. p. purified by distillation at temperature 30-120°C, pigment as waste in manufacturing titanium dioxide formed at step of synthesis of titanium dioxide with the content of titanium dioxide 98 mas. p. p., a filling agent as waste of air-slaked lime in manufacturing perchloric acid formed at step for quicklime slaking with the content of calcium hydroxide 90 mas. p. p. Invention provides expanding assortment of paint and varnish materials, eliminates deficit of expansive components, improved technological properties of enamel and covers based on thereof. Proposed materials can be used for protective-decorative coating surfaces of different nature, in particular, metallic, concrete, asphalt, asphalt concrete ones and can be used in different branches of industry.

EFFECT: improved, enhanced and valuable properties of enamel.
