摘要:

选择双组份缩合型室温硫化（ＲＴＶ）硅橡胶作为包覆层的基材，分析了硅橡胶包覆层的增强途径，考查了四种填料对硅橡胶包覆剂力学性能的影响规律，并对白炭黑补强的机理进行了讨论，最后优化研究了固体组份的添加量。

Abstract:

Silicone inhibitors for DB/CMDB propellants are developed from the room temperature vulcanized elastomers which are two-component systems crosslinking through a condensation mechanism. An analysis of reinforcing methods of silicone inhibitors is presented in this paper. The effects of four kinds of fillers on mechanical properties of silicone inhibitors and the reinforcing mechanism of white carbon black are also discussed. By using the orthogonal design and through the analysis of experimental results, the optimal contents of curing components are obtained as well.
