摘　　要：以全氟聚醚硅烷、氟烃基硅烷、氨基硅烷、γ-甲基丙烯酰氧基丙基三甲氧基硅烷和苯基硅烷等为原料,经水解共缩聚,制备得到γ-甲基丙烯酰氧基丙基与全氟聚醚共改性的光固化氟硅树脂(PFSi)。通过红外光谱(FT-IR)、扫描电镜(SEM)等表征方法对其进行测试,并对涂层整体性能进行研究。结果表明:氟组分质量含量为20%时所制树脂所构筑的光固化涂层UVPFSi表面疏水效果较好,水接触角可达到118°,透光率达到90.83%,涂层经5%硫酸浸泡及耐盐雾测试后表面完好,整体表现出优异的耐化学腐蚀性。The photocurable fluorosilicone resin(FPSi)co-modified byγ-methylacryloxy-propyl trimethoxy-silane and phenylsilane was prepared from perfluoropolylether,fluoroalkyl silane,amino-silane,γ-methylacryloxy-propyl trimethoxy-silane and phenylsilane by hydrolysis and co-condensation.The coating was characterized and tested by FT-IR and SEM,and the overall properties of the coating were studied.The results showed that,when the fluorine content was 20wt%,the surface hydrophobic effect of the photocurable coating UVFPSi was good,with a water contact angle of 118°,and a light transmittance of 90.83%.The coating surface was intact after 5wt%sulfuric acid immersion and salt spray resistance test,demonstrating excellent chemical resistance.
