将二种有机膨润土分别加入硅橡胶胶料,研究和分析了胶料的性能变化情况。结果确认:硅橡胶的耐热氧化老化性提高,拉伸强度和相对伸长率保持不变,硬度略有增大。含二甲基二烷基氯化铵的有机膨润土的改性效果更佳。
The two kinds of organic bentonite were added to the silicone rubber compound to study and analyze the rubber compound performance changes. The results confirmed: silicone rubber thermal aging resistance, tensile strength and relative elongation remain unchanged, slightly increased hardness. Modified with dimethyl dialkyl ammonium chloride organic bentonite better.
