摘要

FIELD: chemistry.;SUBSTANCE: invention relates to an anti-fouling paint composition with high content of non-volatile components used for forming an anti-fouling coating film on the surface of a base such as underwater structures, outer sides of ships, fishing nets and fishing installations. The composition contains: (A) a carboxyl group-containing copolymer which has a structural unit obtained from a monomer (a1) of an unsaturated carboxylic acid and a structural unit obtained from another monomer (a2) of an unsaturated compound which copolymerises with monomers (a1) of the unsaturated carboxylic acid, and has average molecular weight of 1000-6000, measured using gel-penetrating chromatography, (B) a polyvalent metal compound capable of reacting with the carboxyl group of copolymer (A),and (C) an anti-fouling agent, where monomer (a1) of unsaturated carboxylic acid is (meth)acrylic acid, the other monomer (a2) is an unsaturated compound which is at least one type of monomer selected from a group consisting of alkyl(meth)acrylate and styrene and the polyvalent metal compound (B) is zinc oxide.;EFFECT: anti-fouling paint composition with high content of non-volatile components enables to obtain an anti-fouling coating film which has less effect on the environment and human body and has high resistance to fouling, retains these properties and has excellent mechanical strength.;62 cl, 22 dwg, 10 tbl, 4 ex
