| 中文摘要: |
| 研究3种综合促进剂（DG-1，DG-2，EG-3）对三元乙丙橡胶（EPDM）性能的影响。结果表明：综合促进剂DG-2的熔点较低，有助于改善胶料的加工流动性；与综合促进剂DG-1和EG-3胶料相比，综合促进剂DG-2胶料的ts1和t10较长，t90较短，加工安全性好，硫化速率最快，抗硫化返原性能、物理性能和耐热老化性能较好。 |
| 英文摘要: |
| The effects of three complex accelerators （DG-1，DG-2，DG-3）on the properties of ethylene-propylene-diene rubber（EPDM）was studies.The results showed that the melting point of the complex accelerator DG-2 was relatively low，which helped improve the processing fluidity of the compound.Compared with the complex accelerators DG-1 and DG-3 compounds，complex accelerator DG-2 compound exhibited longer ts1 and t10，shorter t90，the better processing safety，the faster curing rate and the better anti-reversion property，physical property and thermal aging resistance. |
