| 中文摘要: |
| 研究以VNB（5-乙烯基-2-降冰片烯）为第三单体的三元乙丙橡胶（VNB-EPDM）胶料的耐热氧老化性能，并与以ENB（5-亚乙基-2-降冰片烯）为第三单体的EPDM（ENB-EPDM）和二元乙丙橡胶（EPM）对比。结果表明：与ENB-EPDM胶料相比，VNB-EPDM胶料的硫化速度较快，交联程度较高，耐高温性能更好；以VNB-EPDM作为主体材料，采用过氧化物硫化体系和防老剂445/MB/TMQ（并用比为1/1/1）的复合防护体系，胶料的耐高温（175 ℃）性能与价格较高的乙烯-丙烯酸酯橡胶相当，可用于制备耐高温橡胶制品。 |
| 英文摘要: |
| The heat and oxygen aging properties of VNB（5-vinyl-2-norbornene） as the third monomer of EPDM（VNB-EPDM） as well as ENB（5-ethylene-2-norbornene）-EPDM and ethylene propylene rubber（EPM）were discussed.The results showed that compared with ENB-EPDM compound，VNB-EPDM compound had faster curing speed，higher crosslinking degree，and relatively high temperature resistance，by utilizing VNB-EPDM as the main material，and using peroxide as vulcanizing agent，the antioxidant composite system of antioxidant 445/MB/TMQ（1/1/1），the properties of high temperature（175 ℃） resistance was similar as AEM，which could be used to make high temperature resistant rubber products. |
