Preparation and properties of acryloxy/perfluoropolyether group co-modified fluorosilicone resin
The photocurable fluorosilicone resin(FPSi)co-modified by y-methylacryloxy-propyl trimethoxy-silane and phenylsilane was prepared from perfluoropolylether,fluoroalkyl silane,amino-silane,y-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.
