摘要
制备耐油室温硫化(RTV)硅橡胶,并对其性能进行研究。耐油RTV硅橡胶优化制备条件为:端乙烯基硅油(粘度为1.5Pa·s)/支链型乙烯基硅油(粘度为4.8Pa·s)用量比100/20,含氢硅油(氢质量分数为0.01)/乙烯基摩尔比2,白炭黑/云母用量比15/15。采用该条件制备的RTV硅橡胶物理性能和耐油性能良好。
The oil resistant room temperature vulcanized（RTV） silicone rubber was prepared,and its properties were investigated. The optimized formulation was as follows：the blending ratio of vinyl- terminated polydimethylsiloxane with viscosity of 1. 5 Pa· s/vinyl-branched polydimethylsiloxane with viscosity of 4.8 Pa ·s 100/20,mole ratio of hydrogen-containing silicone oil（the mass fraction of hydrogen was 0.01）/vinyl 2,and the blending ratio of silica/mica 15/15. The RTV silicone rub- ber prepared by optimized formulation had good physical properties and oil resistance.
