以正硅酸乙酯(TEOS)、苯基三甲氧基硅烷(PTMOS)、γ-(2,3-环氧丙氧)丙基三甲氧基硅烷(KH-560)和二甲基二甲氧基硅烷为原料,通过水解共缩聚的方法制备了高韧性无底涂耐磨有机硅树脂,并涂覆于聚酯(PET)薄膜表面,于120℃下固化.研究了各原料比例对树脂性能的影响,对树脂膜涂层的柔韧性、硬度、耐磨性及附着力进行了分析,并对树脂膜进行了红外光谱、扫描电镜和热重性能表征.结果表明:当合成树脂中TEOS与PTMOS摩尔比为0.9、KH-560占2.24％(wt,质量分数,下同)、二甲基二甲氧基硅烷用量为1.3％,硅树脂涂膜拥有较好的性能,涂膜的附着力能够达到1级、硬度到达5H、耐磨等级达到优、水接触角达到89.6°,耐80℃水煮能力较好.“,”The high flexibility primer-free and wear resistant organic silicon resin was synthesized with tetraethoxysilane(TEOS),phenyltrimethoxysilane(PTMOS),gamma (2,3-epoxypropoxy)propyltrimethoxysilane (KH-560),dimethyldimethoxysilane as the raw material,and then coating on PET film and curing at 120℃. The flexibility,hardness,wear resistance and adhesion of coating were studied through changing the property of raw material. The coating was analyzed by FT-IR,SEM and TGA.Results showed that the molar ratio of TEOS to PTMOS was 0.9,the ratio of KH-560was 2.24wt％,dimethyldimethoxysilane dosage was 1.3wt％,the silicone resin coating had good properties,the film adhesion can reach 1level,the hardness reached 5H,the wear resistance achieved the best grade and the water contact angle was 89.6°,and 80℃centigrade boiled resistant ability was good.
