高硬度有机硅橡胶耐热性能与回弹性能的改善

Improvement of resilience and thermal stability of hyper-hard silicone rubber composite

通过添加气相法白炭黑增加硅橡胶硬度,添加金属氧化物(二氧化铈)改善硅橡胶热稳定性。研究了不同粒径、不同用量二氧化铈对硅橡胶耐热性的影响,并分析了填料对硅橡胶回弹性能的影响。

In this paper, silica was selected to improve the hardness of silicone rubber, cerium dioxide was selected to improve the thermal stability, we also investigated the effect of different size and different dosage of cerium dioxide to the thermal stability of high hardness silicone rubber, and analysed elasticity especially.
