摘　　要：合成了水解型乙烯基不饱和丙烯酸锌小分子单体,利用此单体自由基聚合制备金属丙烯酸锌基自抛光型树脂。采用该丙烯酸锌树脂制备自抛光防污涂料,氧化亚铜为主要防污剂,以符合环保要求的有机防污剂奥麦丁铜(CuPT)相复配。实验结果表明,丙烯酸锌小分子水解单体的质量分数为50%~55%时,涂层水解速率达到最佳状态。防污涂膜抛光速率1个月6~8μm、铜离子(Cu^(2+))释放速率25μg/(cm^(2)·d),奥麦丁铜释放速率10μg/(cm^(2)·d),实海挂板验证36个月具有良好的防污效果。A hydrolyzed vinyl unsaturated zinc acrylate small molecule monomer was synthesized,and a metal zinc acrylate-based self-polishing resin was prepared by free radical polymerization of this monomer.Self-polishing antifouling coatings were prepared using the zinc acrylate resin,with cuprous oxide as the main antifouling agent,and compounded with the environmentally friendly organic antifouling agent,copper oxybutyrate(CuPT).The experimental results indicate that the optimal hydrolysis rate of the coatings is achieved when the content of zinc acrylate small molecule hydrolysis monomer is 50% to 55%.The polishing rate of the antifouling coatings is 6~8 μm/month,the leakage rate of copper ions(Cu~(2+)) is 25 μg/(cm~2·d),and the release rate of CuPT is 10 μg/(cm~2·d).The actual sea hanging plate has verified good antifouling effect for 36 months.
