| 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. |
