摘　　要：以甲基丙烯酸甲酯、丙烯酸丁酯、丙烯酸异辛酯、丙烯酸甲氧基乙酯、丙烯酸三异丙基硅酯为单体,制备了丙烯酸硅烷酯基体树脂,将其与韧性树脂(液态聚丁二烯)共同作为成膜共混树脂,并以Cu_(2)O作为主要防污剂组分、吡啶硫酮铜(CuPT)和代森锌(Zineb)为辅助有机防污剂组分,配制了柔性自抛光防污涂料。对丙烯酸硅烷酯基体树脂进行了FTIR表征和玻璃化转变温度(Tg)测定,对成膜共混树脂进行了SEM测试,对柔性自抛光防污涂料进行了柔韧性、附着力、吸水率和防污性能测试。结果表明,丙烯酸硅烷酯基体树脂的Tg=–20.54℃时,具有较好的物理机械性能;韧性树脂可以作为外增塑手段增加丙烯酸硅烷酯基体树脂的柔韧性,当m(丙烯酸硅烷酯基体树脂)∶m(韧性树脂)=7∶3时,成膜共混树脂的相容性最好;柔性自抛光防污涂料柔韧性为1级,在弹性体基材表面附着力达到4.0 MPa;经过60 d测试,吸水率为1.1%~1.2%;浅海浸泡挂板36个月显示出明显的防污效果。Silyl ester acrylate matrix resin,prepared from monomers of methyl methacrylate,butyl acrylate,isooctyl acrylate,methoxyethyl acrylate and triisopropyl silicyl acrylate,were combined with ductile resin as film-forming blend resin to obtain a flexible self-polishing antifouling coating with Cu_(2)O as main antifouling agent,copper pyrithione(CuPT)and zinc(Zineb)as auxiliary organic antifouling agent.The silyl ester acrylate matrix resin was characterized by FTIR and tested for its glass transition temperature(Tg).The film-forming blend resin was analyzed by SEM,followed by evaluation on the flexible self-polishing anti-fouling coating for its flexibility,adhesion,water absorption and anti-fouling properties.The results showed that the silyl ester acrylate matrix resin with a Tg of–20.54℃had good physical and mechanical properties,while the addition of ductile resin as external plasticizer increased the flexibility of the matrix resin.The blended resin with m(silyl ester acrylate resin)∶m(ductile resin)=7∶3 displayed the best compatibility.The flexible self-polishing antifouling coating showed grade 1 in flexibility,and the adhesion force of 4.0 MPa on the surface of elastomer substrate.Moreover,the coating exhibited a water absorption of 1.1%~1.2%after 60 d of testing,and significant antifouling effect in the 36-month shallow water immersion test.
