摘要
讨论了双组分室温硫化硅橡胶的耐热性能,介绍了其热氧老化机理,并分析了提高耐热性能的途径,主要包括:改变其主链与侧基的结构,消除硅羟基,使用新型硫化体系,加入硅氮类化合物、耐热添加剂和硅树脂等。
The heat resistance of the two-component room temperature vulcanized silicone rubber was discussed,and the mechanism of thermal oxidative aging was introduced,and the methods improving the heat resistance of the two-component room temperature vulcanized silicone rubber were analyzesd,mainly including changing the structure of backbone and side group,eliminating hydroxyl groups,using new curing systems,adding silicone nitrogen compounds or heat resistant additives or silicone resin.
