摘  要:本文利用端羟基聚二甲基硅氧烷的室温硫化特性,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。我们用50000cps的端羟基聚二甲基硅氧烷、350cps的二甲基硅油、HMDZ用量为20%时处理过的白炭黑以及硅微粉,以100:90:40:60的比例,制作了硅橡胶防水涂料组分A,测试时添加0.5%的粘接促进剂与组分B混合。多项指标均达到和超过聚氨酯防水涂料国家标准的要求。

关键词:端羟基聚二甲基硅氧烷;室温硫化;防水;有机硅类涂料。

 

Abstract:The use of hydroxyl poly two of room temperature vulcanization characteristics was, through the reinforcement, increase the plastic, incremental and suitable vulcanization system preparation a can in room temperature vulcanization into elastomer, and of the basic level have adhesion and have waterproof function of organic silicon kind of coating. We use the 50000 CPS Hydroxy terminated poly (dimethylsiloxane),the 350 CPS dimethyl silicone , HMDZ dosage for 20% when treated carbon black and silica powder white, with a 100:90:40:60 the ratio, made a silicone rubber waterproofing paint components A, test by adding 0.5% to promote bonding agent and component B mix. Many indexes meet and exceed polyurethane waterproof coating of the national standard. 

Key words:The hydroxyl poly two methyl;Room temperature vulcanization;waterproof;Organic silicon kind of coating
