| 中文摘要: |
| 研究三元乙丙橡胶（EPDM）第三单体（亚乙基降冰片烯）含量和助交联剂三羟甲基丙烷三甲基丙烯酸酯（TMPTMA）用量对EPDM胶料耐磷酸酯液压油性能的影响。结果表明：在EPDM第三单体含量相同时，在试验范围内，随着助交联剂TMPTMA用量的增大，胶料的硫化速率加快，交联密度增大，耐磷酸酯液压油性能提高；在助交联剂TMPTMA用量相同时，随着EPDM第三单体含量的增大，胶料的硫化速率加快，交联密度增大，耐磷酸酯液压油性能提高；对于第三单体含量较小的EPDM，当助交联剂TMPTMA用量超过一定值后，其用量增大，胶料的交联密度增幅较小，但耐磷酸酯液压油性能持续提高。 |
| 英文摘要: |
| The effect of the third monomer（ethylene norbornene） content of ethylene propylene diene
rubber（EPDM） and the amount of the co-curing agent trimethylolpropane trimethacrylate（TMPTMA） on
the phosphate hydraulic oil resistance of EPDM compound was investigated. The results showed that，when
the third monomer content was the same，with the increase of the amount of TMPTMA in the experimental
range，the vulcanization rate，crosslinking density and phosphate hydraulic oil resistance of the compound
were improved. When the amount of TMPTMA was the same，with the increase of the content of the third
monomer，the vulcanization rate，crosslinking density and phosphate hydraulic oil resistance of the compound
increased. For EPDM with low third monomer content，when the amount of TMPTMA exceeded a certain
value，with the increase of the amount of TMPTMA，the crosslinking density of the compound increased
slightly，but the phosphate hydraulic oil resistance increased continuously. |
