以全氟烷基乙基甲基丙烯酸酯为功能单体,采用自由基聚合法制备了具有防污性能的低表面能氟/硅丙烯酸树脂涂层,重点探讨了有机氟含量对树脂涂层的接触角、玻璃化转变温度、附着力、硬度等性能及单体转化率的影响,确定了氟/硅丙烯酸涂层的最佳制备条件。结果表明,氟/硅单体成功与丙烯酸单体发生共聚,当氟/硅丙烯酸涂层中的氟质量分数为14.60%时,树脂涂膜的接触角为103.7°,与基体结合力优异,同时具有良好的防腐性能。
A series of fluorine/silicone modified antifouling coating with low surface energy were synthesized by radical polymerization used perfluoroalkyl ethyl methacrylate as functional monomer.The main properties of hydrophobic coating such as contact angle,glass transition temperature,adhesion,hardness and the conversion of monomer were researched in detail when the content of fluorine monomer in the coating was changed.Then the best formula of coating were obtained.The results showed that fluorine and silicone monomers were copolymerized with acrylic successfully,and when the content of fluorine monomer was 14.60%,the contact angle of the coating was 103.7°.What's more,the coating not only had excellent adhesion to the substrate but also had corrosion resistance.
