| 中文摘要: |
| 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1.5 Pa·s）/支链型乙烯基硅油（粘度为4.8 Pa·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。 |
| 英文摘要: |
| 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 rubber prepared by optimized formulation had good physical properties and oil resistance. |
