摘要
本文首先制备了一种高有机硅含量的硅丙乳液,然后利用所制备高有机硅含量的硅丙乳液杂化改性硅溶胶作为主要成膜物质,并辅以适当的颜料,填料,助剂等制备了硅丙乳液改性硅溶胶基无机涂料(TGS-Si)。对改性后的硅溶胶基无机涂料涂膜性能研究表明:涂膜表干时间1.5 h;涂膜正常,无气泡,无裂纹;涂膜水浸泡168小时,无气泡,无起皮,无脱落;涂膜碱浸泡168小时,无气泡,无起皮,无脱落;涂膜耐洗擦2200次无漏底;柔韧性为1 mm;铅笔硬度3 h,水接触角度为118°,具有阻燃性能。
In this paper, high organic silicone content of silicon-acrylic emulsion modified silica sol was prepared by hybrid reaction between a high organic silicone content of silicon-acrylic emulsion and silica sol. Then appropriate pigments, fillers, additives, etc. were added to form silicon-acrylic emulsion modified silica sol based inorganic coating(TGS-Si). Studied on performance of coating revealed that the TGS-Si coating has excellent hydrophobicity, washable resistance and flame retardant performance, compared with the performance of commercially available silicon-acrylic emulsion modified silicone sol-based coating(TS-Si).
