摘　　要：目的合成具有溶蚀性能的丙烯酸基体树脂,用该树脂制备中期效短期效溶蚀型海洋防污涂料。方法自由基聚合法合成具有溶蚀性能的丙烯酸基体树脂,用该基体树脂配以市场价格较便宜性价比较高的有机类防污剂代森锌、吡啶硫酮锌、敌草隆等,颜填料,助剂等制备溶蚀型海洋防污涂料。通过实海挂板试验、耐淡水浸泡测试、涂层微观样貌对涂层进行表征。结果丙烯酸基体树脂聚合物的数均分子量控制在25000左右较为合适,即聚合反应温度控制在110℃,引发剂用量为4份时较为合适。羧酸单体的含量为25%~30%时,基体树脂具有较好的溶蚀性能。制备的溶蚀型防污涂料经24个月实海挂板试验验证,具有优异的防污期效,经过12个月淡水浸泡,涂层不起泡、不脱落。防污涂层表面微观样貌表征,基体树脂的溶蚀性能,防污剂溶出后,涂层表面粗糙度增大,表面留有孔洞。结论该溶蚀型防污涂料具有优异的防污性能,能够防止海洋附着生物对船底和其他海洋设施的污损,可适用于中小型渔船对短期效海洋污损防护需求。With the progress of human society and the continuous development and updating of marine coating technology,tin-free self-polishing antifouling coating technology has gradually become the mainstream technology of biofouling protection after many product updates and iterations.However,in some cases such as small and medium-sized fishing boats,the application method is mostly roller coating.The single-coating film is thin.The ship owners mostly use the tidal range time for application,and the application time is tight,so it is difficult to meet the requirements of conducting roller coating twice.Even if it can be roller coated twice,the film thickness is difficult to meet the requirements.Self-polishing antifouling coatings have high requirements for film thickness,and the required film thickness must be reached to ensure the antifouling performance.In addition,the cost of self-polishing antifouling coating is high,so it is not suitable for small and medium-sized fishing boats.At this time,the ablative type antifouling coating shows its advantages.In response to market demand,the work aims to develop an ablative type antifouling coating,which can meet the needs of small and medium-sized ships.An acrylic matrix resin with ablative property was synthesized and used to prepare the ablative marine antifouling coating.The acrylate matrix resin with ablative properties was synthesized by radical polymerization.The hydrogen ion electrolyzed from the carboxylic acid group of the side group of the matrix resin slowly dissolved with the hydroxide ion in seawater.The bactericide in the antifouling coating slowly dissolved into the seawater to prevent marine organisms from adhering.In order to ensure the ablative performance of the matrix resin,the hydrogen ions electrolyzed from the carboxylic acid group of the matrix resin must reach certain content.The amount of acrylic acid or methacrylic acid used must be within the appropriate range.The antifouling coatings were prepared with this resin and organic antifouling agent Zine
