【摘要】 研究了普通硫化体系 (CV)、半有效硫化体系 (SEV)和有效硫化体系 (EV)的硫化特性及其对EPDM力学性能和耐热老化性能的影响 ,以及防老剂对EPDM耐热老化性能的影响。试验结果表明 ,采用SEV和EV体系硫化的硫化胶有较好的耐热老化性能 ,采用CV体系的硫化胶有较好的力学性能 ;防老剂对EPDM的耐热老化性能无明显影响。更多还原

【Abstract】 The influence of different curing systems,such as CV,SEV and EV on curing behavior,mechanical properties and heat aging properties of EPDM as well as antioxidant on its heat aging properties were investigated.The results showed that the EPDM cured with SEV or EV had better heat aging properties and that cured with CV had better mechanical properties;and antioxidant gave little effect on heat aging properties of EPDM.更多还原
