摘要
讨论了影响甲基嵌段室温硫化硅橡胶硫化时间的主要因素,如:乙氧基与硅羟基的量之比,甲基三乙氧基硅烷低聚物的pH值、铁离子的含量,以及温度、湿度和催化剂的用量等;并介绍了预防和控制这些影响因素的方法。
It was discussed that the main factors having effect on the vulcanization time of RTV block methyl silicone rubber, such as the mol ratio of ethoxyl and silicone hydroxyl, the pH value of methyltriethoxysilane, and the content of iron ions impurity in methyltriethoxysilane, temperature, moisture, and the quantity of catalyst. It also was introduced the ways of preventing and controlling the factors.
