Problems solved by technology

[0003] Studies have shown that the self-polishing performance of acrylic metal salt resin is the result of ion exchange and hydrolysis between metal ions and sodium ions in seawater, but the resin itself does not have biocidal properties, and thus introduces a large amount of activity A report on enhancing the antifouling performance of coatings by releasing biocidal functional groups through hydrolysis

Abstract

The invention relates to rosin organic acid metal salt resin with chemical structural characteristics and performances of acrylate metal salt resin and a preparation method and application of the rosin organic acid metal salt resin. The rosin organic acid metal salt resin disclosed by the invention has a structural formula of R-X-R1 (I), wherein R refers to acid radicals of benzoic acid, naphthenic acid, salicylic acid, furoic acid, parachlorobenzoic-acid, 2,4-dichlorobenzoic acid, proline, leucine, phenylalanine or arginine; and X refers to Zn<2+>, Cu<2+>, Mg<2+> or Ca<2+> metal ions; and R1 is selected from acid radicals of colopholic acid, ionated rosin acid or dimeric colopholic acid. The rosin organic acid metal salt resin disclosed by the invention is environment-friendly, has the similar chemical structural characteristics with the acrylate metal salt resin and is excellent in matching property with other components in the coating formula. The self-polishing antifouling paint taking the resin as a film forming matter is high in coating toughness, excellent in self-polishing performance and long in antifouling period, accords with the environment-friendly development trend of the antifouling coating and has wide application prospects.

Description

【Technical field】 [0001] The invention belongs to the technical field of organic compounds. More specifically, the present invention relates to a kind of rosin organic acid metal salt resin having the chemical structure characteristics and properties of acrylic acid metal salt resin, also relates to the preparation method of said rosin organic acid metal salt resin, also relates to said rosin organic acid metal salt Use of resins in environmentally friendly self-polishing antifouling coatings. 【Background technique】 [0002] In antifouling coatings, resin is the key component that affects its antifouling performance, and resins with excellent properties are the premise for developing high-performance antifouling coatings. Since organotin resins have been completely banned, the development of new tin-free self-polishing resins based on the chemical structure characteristics and self-polishing mechanism of organotin self-polishing resins has become a research and development ...
