海洋生物污损给人类海洋活动带来了严重的危害，近年来大量使用有机锡和氧化亚铜涂料防止海洋污损生物，对海洋藻类和鱼类等生物带来了严重的危害。随着人们对生态环境的日益重视，研究高效、低毒、绿色的海洋防污涂料，对保护海洋环境有重要的意义。. 本项目以环境友好的防污杀菌化合物1,2-苯并异噻唑啉-3-酮（BIT）为研究目标，选择杀菌抑藻活性良好的结构体系，在BIT分子中引入双键结构制备成可聚单体，与丙烯酸酯共聚，合成侧链接枝BIT功能结构的丙烯酸酯预聚物，再与有机酸锌反应，制备成BIT功能化的丙烯酸锌防污涂料。研究涂料的结构特征、水解性能、BIT释放性能及海洋防污性能，研究聚合物结构与防污性能之间的关系。掌握制备此类接枝型自抛光防污涂料的关键技术，解决现有防污涂料中于氧化亚铜的大量释放而带来的海洋环境污染问题。获得具有优良防污、杀菌性能的绿色海洋防污涂料，减少海洋污染，保护海洋生态环境。

There are great damages of marine biofouling to mankind marine business activities. Recently, for the prevention of the marine fouling organisms, the widely used of organic tin and cuprous oxide antifouling paints have serious harm to the algae and fish and other marine creatures. Along with the increasing attention to the marine ecological environment, it is important to developing excellent marine antifouling coatings with low-toxicity, high-efficient and environmentally friendly properties for the protection of the Marine environment.. The environment friendly 1-2-benzisothiazol-3-one (BIT) derivatives were selected as the research objectives in this topic. The compounds with favorable bacteria and algal inhibiting activities will be closed and be prepared to polymerizable monomers by introduced a vinyl in the molecular structures. The acrylate prepolymers with BIT units on side chain would be designed and synthesized by the copolymerized of BIT monomers with acrylic esters. The acrylic marine antifouling coatings with BIT function group on side chain would be prepared through the reaction of the prepolymer with organic acid zinc. The structure characteristics, hydrolysis performance, BIT release rate and marine antifouling properties, as well as the structure-activity relationships of the functional coatings would be studied. . The key technologies for the preparation of the functional self-polishing antifouling paints would be mastered, and the marine environmental pollution problems duo to the large releasing of tin and cuprous oxide from antifouling paint would be avoided. And a series of green marine antifouling coatings with excellent antifouling and antibacterial properties would be obtained for the reduction of the marine pollution and the protection of the marine ecological environment.
