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
The present invention relates to the antifouling copolymer resins of a kind of polyacrylic ester, particularly relate to a kind of side chain and contain antifouling copolymer resins of polyacrylic ester of BIT and preparation method thereof.
Background technology
Adhering to of marine fouling organism causes serious harm to boats and ships and maritime facilities, to the mankind, brings huge financial loss, and the most direct approach addressing this problem is brushing antifouling paint.Isothiazolinone biocide agent fungicidal activity is strong, under the concentration of about 0.5～1ppm, just can suppress widely all kinds of microbial growths, and energy fast degraded biologically, environmentally safe, be therefore widely used in the fields such as industrial circulating cooling water, weaving, coating, agricultural environmental protection.The nineties in 20th century, U.S. Rohrnhaas company successfully develops the chloro-Kathon of 4,5-bis-(Seanine 911), and with addition manner, is applied to United States Naval ship antifouling paint as high-efficiency pollution-proof agent.Because Seanine 911 adds in the middle of coating with small molecules, therefore according to Fick's law, the application initial stage, stain control agent release rate in coating is too fast, after ship's navigation for some time, the anti-fouling effect of coating will decline, and antifouling coating is difficult to reach the even control release of stain control agent as stanniferous self polishing copolymer antifouling paint, thereby causes the antifouling time limit relatively short.The invention provides a kind of side chain and contain antifouling copolymer resins of polyacrylic ester of BIT and preparation method thereof, this antifouling copolymer resins molecular weight of polyacrylic ester with sterilizing function is larger, therefore in application process, being difficult for diffusion runs off, simultaneously again can be by the hydrolysis of ester group bactericide-release equably, thereby sterilant is efficiently utilized, can overcome the deficiency of above-mentioned antifouling paint.
Summary of the invention
The invention provides a kind of side chain containing antifouling copolymer resins of polyacrylic ester of BIT and preparation method thereof, preparation is simple for antifouling copolymer resins, and antifouling paint has good antifouling property and from polishing performance.
Side chain, containing the antifouling copolymer resins of polyacrylic ester of BIT, is characterized in that its structure represents with following general formula:
