Problems solved by technology

Since Seanine 911 is added to the coating with small molecules, according to Fick’s diffusion law, the antifouling agent in the coating is released too quickly at the initial stage of coating, and the antifouling effect of the coating will decrease after the ship sails for a period of time. It is difficult for antifouling coatings to achieve uniform and controlled release of antifouling agents like tin-containing self-polishing antifouling coatings, resulting in a relatively short antifouling period

Abstract

The invention relates to polyacrylate antifouling copolymerization resin with a side chain comprising benzisothiazolinone and a preparation method thereof. The clear and transparent polyacrylate antifouling copolymerization resin with the side chain comprising the benzisothiazolinone can be obtained by performing solution copolymerization reaction on a N-substituted propenyl acyloxy methyl benzisothiazolinone functional monomer and other one or two or three alkenyl-containing monomers in an organic solvent. The sterilizing copolymerization resin is used as a film forming agent of antifouling paint and has excellent antifouling performance and self-polishing performance; and the resin preparation process is simple and easy to operate.

Description

technical field [0001] The invention relates to a polyacrylate antifouling copolymer resin, in particular to a polyacrylate antifouling copolymer resin containing benzisothiazolinone in a side chain and a preparation method thereof. Background technique [0002] The attachment of marine fouling organisms has caused serious harm to ships and marine facilities, and brought huge economic losses to human beings. The most direct way to solve this problem is to apply antifouling paint. Isothiazolinone fungicides have strong bactericidal activity, can widely inhibit the growth of various microorganisms at a concentration of about 0.5-1ppm, and can quickly biodegrade and are environmentally safe, so they are widely used in industrial circulating cooling water, Textile, paint, agriculture, forestry and environmental protection and other fields. In the 1990s, Rohrnhaas Company of the United States successfully developed 4,5-dichloro-2-n-octyl-4-isothiazolin-3-one (Seanine 911), and u...
