| The low surface energy antifouling coatings have anti-fouling, self-cleaning function because of low surface energy. The foulings are difficult to stick to the surface of antifouling coating due to their low surface tension. The low surface energy antifouling coatings are widely used in ships, buildings, ports and anti-pollution facilities, such as rubber dam. Due to the low surface energy, antifouling coatings have no harmful substances, will not pollute the environment. In this paper, based on the theory of organic silicon with low surface energy antifouling, four kinds of organic silicone modified resin were prepared by free radical polymerization, and the antifouling performance on the rubber dam and the tin plate were also evaluated.1. In this article, Vinyltrimethoxysilane, methacryloxy propyl trimethoxyl silane, ethyl methacrylate, polyethylene glycol single methyl ether and butyl acrylate were selected as monomer. The functional organic silicon resin was synthesized through free radical polymerization. The optimum ratio of monomer, Tg and the molecular weight of copolymer were characterized by polymer properties. The contact angle, adhesion strength, water resistance and antifouling property of coatings were discussed, so we got much better coating formula.2. Due to the function coating adhesion was low, in order to improve the adhesion of coating on the rubber dam, so good cohesiveness of glycidyl methacrylate was introduced into organic silicon resin to synthesized APEG copolymer via radical polymerization. The optimum ratio of monomer, Tg and the molecular weight of copolymer were characterized by polymer properties. The contact angle, adhesion strength, water resistance and antifouling property of coatings were discussed, so we got much better coating formula.3. In order to reduce the surface energy of function coating, tri (isopropyl) silylacryate, polyethylene glycol single methyl ether, butyl acrylate, ethyl methacrylate, methacryloxy propyl trimethoxyl silane, were selected as monomer. The functional organic silicon resin was synthesized through free radical polymerization. The optimum ratio of monomer, Tg and the molecular weight of copolymer were characterized by polymer properties. In order to get better coating formula, contact angle, adhesion strength, water resistance and antifouling property of coatings were discussed.4. In order to reduce the surface energy of coating, and to improve adhesion. The good cohesiveness of glycidyl methacrylate, butyl acrylate, ethyl methacrylate, tri (isopropyl) silylacryate, vinyltrimethoxysilane and glycidyl methacrylate were used as polymerization monomer. The optimum ratio of monomer, Tg and the molecular weight of copolymer were characterized by polymer properties. In order to get better coating formula, contact angle, adhesion strength, water resistance and antifouling property of coatings were discussed. |
