| 中文摘要: |
| 目的 制备环境友好型的海洋防污涂料，即低表面能海洋防污涂料。方法 以含氟单体甲基丙烯酸十二氟庚酯（FMA）和含硅单体γ-(甲基丙烯酰氧)丙基三甲氧基硅烷（KH570）为改性单体，以甲基丙烯酸缩水甘油酯（GMA）和丙烯酸丁酯（BA）为主要单体，通过自由基共聚合制得氟硅改性的聚丙烯酸酯树脂层，采用傅里叶红外光谱和差示扫描量热法，分别对改性聚丙烯酸酯树脂的化学结构和热性能进行了分析表征。通过对改性聚丙烯酸酯树脂涂层的扫描电子电镜（SEM）分析、接触角测试、表面能计算、附着力测试、耐酸碱测试，防污性能测试等，探讨了FMA和KH570含量对树脂涂层性能的影响。结果 当FMA、KH570的含量分别为15%、10%时，树脂涂层的接触角达到112.0°，表面能低至18.425 mJ/m2，附着力达到1级，具有良好的防污性能。结论 氟单体和硅单体单独参与共聚改性均具有降低聚丙烯酸酯树脂表面能的作用，而氟单体和硅单体共同改性聚丙烯酸酯对树脂涂层表面能的降低更显著，可作为一种很有潜力的海洋低表面能防污涂料。 |

| The work aims to prepare environment-friendly marine antifouling paints, i.e., marine antifouling paints of low surface energy. With glycidyl methacrylate (GMA) and butyl acrylate (BA) as primary monomers, and dodecafluoroheptyl methacrylate (FMA) and methacryloxy propyl trimethoxyl silane (KH570) as modified monomers, a fluorine-silicon modified polyacrylate resin layer of low surface energy was prepared by free radical copolymerization. Chemical structure and thermal properties of the resin were analyzed and characterized by adopting Fourier transform infrared spectroscopy and differential scanning calorimetry. Effects of FMA and KH570 content on resin coating performance were discussed based on scanning electron microscope (SEM), contact angle test, surface energy calculation, adhesion test, acid and alkali resistant test and antifouling property test of the resin coating. The contact angle could reach 112.0°, surface energy to 18.425 mJ/m2, adhesion to level 1 and good antifouling property is achieved when the content of FMA and KH570 was 15% and 10%, respectively. Individual involvement of fluorine monomer and silicon monomer in copolymerization modification of polyacrylate resin can reduce surface energy of resin coating, while joint involvement of the two monomers can significantly reduce the surface energy. Therefore, the modified polyacrylate resin can be used as a promising marine antifouling paint of low surface energy. |
