摘　　要：利用改性后的端羟基聚二甲基硅氧烷(HTPDMS 20)的室温硫化特性,通过补强、增塑、增量以及选用合适的硫化体系制备一种可以在室温下硫化成弹性体,并对基层具备一定附着力以及具备防水功能的有机硅类涂料。通过单因素分析优化HTPDMS 20、二甲基硅油和HMDZ用量,得到最佳配方,并测试该配方防水涂料的性能。结果表明,最佳配方为50 Pa·s HTPDMS 20、0.35 Pa·s的二甲基硅油和HMDZ用量为20%时处理过的白炭黑,混合比例为100:90:40:60,测试时添加0.5%的粘接促进剂。该配方涂料的多项指标均达到和超过聚氨酯防水涂料国家标准的要求。Taking advantage of the room temperature vulcanization properties of modified hydroxyl-terminated polydimethylsiloxane(HTPDMS 20),a kind of vulcanization could be prepared at room temperature by reinforcement,plasticization,augmentation and selection of appropriate vulcanization system.It is a silicone-based coating with a certain adhesion to the base layer and a waterproof function.The dosage of HTPDMS 20,dimethicone and HMDZ was optimized by single factor analysis to obtain the best formulation,and the performance of the formulation was tested for waterproof coatings.The results show that the optimal formula is 50 Pa·s HTPDMS 20,0.35 Pa·s dimethyl silicone oil and silica treated with HMDZ content of 20%,and the mixing ratio is 100:90:40:60 with adding 0.5%adhesion promoter.A number of indicators of the formula coating meet and exceed the requirements of the national standard for polyurethane waterproof coatings.
