摘要
研究不同硫化体系对三元乙丙橡胶胶料性能的影响。结果表明:普通硫黄硫化体系硫化胶具有较好的物理性能,但耐老化性能和抗压缩永久变形性能较差;过氧化物硫化体系硫化胶的物理性能仅次于普通硫黄硫化体系硫化胶,同时兼具优异的耐老化性能和抗压缩永久变形性能,其中硫化剂DCP/助交联剂TAIC过氧化物硫化体系硫化胶的综合性能最优。
The effect of different vulcanization systems on the properties of ethylene-propylene diene rubber（EPDM） compounds was studied. The results showed that the vulcanizates with the ordinary sulfur vulcanization system had the best physical properties,but the aging resistance was the worst and compression set was the largest. The physical properties of the vulcanizates with a peroxide vulcanization system were the second,but the vulcanizates possessed excellent aging resistance and low permanent set. The peroxide cured vulcanizates with curing agent DCP and co-agent TAIC had the best overall performance.
