AQUEOUS DISPERSIVE PAINT Russian patent published in 2001 - IPC

FIELD: paintwork materials, particularly, aqueous dispersive paints based on acrylic latexes. SUBSTANCE: aqueous dispersive paint comprises, %: 45-50-% latex of copolymer of butyl acrylate, styrene, methacrylic acid at monomer weight ratio of 57-64 30-35 : 6-8, 50-55; oxyethylated alkylphenol OP-7 or OP-10, 0.1-0.5; tribulyl phosphate, 0.4-0.1; sodium hexametaphosphate or sodium polyphosphate, 0.1-0.5; polyoxymethylene glycol diethyl ether, 0.01-3.0; diethylene glycol or ethylene glycol monoethyl ether, 1.0-3.0; titanium dioxide, rutile, 12-19; yellow ferric oxide pigment or blue phthalocyanine pigment, or green nitrosonaphthol pigment, or red ferric oxide pigment, or scarlet concentrated pigment, or mixtures thereof, 0.01-6.0; calcium carbonate, 5-8;, sodium nitrite, 0.1-1.0; copolymer of acrylic acid, acrylamide, N-methylol acrylamide, 0.1-1.0 at monomer weight ratio of 5-25; 45-85: 10-30 (0.2-0.4), and water. Paint has higher gloss 21-83% greater impact strength, more than 100 kgf.cm. Anticorrosive properties and waterproofness of paintwork coatings on unprimed metallic substrates make it possible to use paint not only in building industry but also in machine building industry. EFFECT: improved properties of the aqueous dispersive paint. 12 ex, 1 tbl
