| 中文摘要: |
| 研究多功能助交联剂CA94-50在三元乙丙橡胶（EPDM）中的应用。结果表明，相较于添加助交联剂TAIC-70，SR350和Ricon 153D的胶料，添加多功能助交联剂CA94-50的EPDM胶料的焦烧时间较长，硫化速度和交联程度提高，硫化胶的硬度、100%定伸应力、拉伸强度和拉断伸长率较高，与金属的粘合强度较大，热氧老化后性能变化不大。 |
| 英文摘要: |
| The application of multifunctional auxiliary crosslinking agent CA94-50 in Ethylene Propylene Diene Monomer（EPDM）.The results showed that，compared with the compound with the addition of auxiliary crosslinking agents TAIC-70，SR350 and Ricon 153D，the scorch time of compound with auxiliary crosslinking agent CA94-50 was prolonged，the curing speed and crosslinking degree were improved，and the hardness，modulus at 100% elongation，tensile strength and elongation at break of the vulcanizate were higher，the adhesive strength with metal was larger，and the properties were changed little after thermal oxidation aging. |
