摘要
研究氯磺化聚乙烯(CSM)和氯化聚乙烯(CM)对三元乙丙橡胶(EPDM)物理性能及耐热老化性能的影响。结果表明:CSM具有独特的氯磺酰基,添加CSM的EPDM胶料定伸应力与拉伸强度增大,耐热老化性能明显提高;添加CM的EPDM胶料耐热老化性能无明显改善;添加气固法CSM3570与溶剂法CSMTS530的EPDM胶料耐热老化性能相近;气固法CSM3570用量为5份时,EPDM胶料耐热老化性能较好,性价比较高。
The influence of chlorosulfonated polyethylene （CSM） and chlorinated polyethylene （CM） on the physical properties and heat aging resistance of EPDM rubber was investigated. Due to the unique chlorosulfonyl groups in CSM, the EPDM rubber blended with CSM showed increased modulus and tensile strength, and possessed quite improved heat aging resistance. The heat aging resistance of the EPDM modified by adding CM had no significant improvement. Moreover, the heat aging properties of EPDM with CSM3570 from gas-solid process and CSMTS530 from solution process were similar. With 5 phr of CSM3570, the properties of EPDM after heat aging were good and the performance-to-cost ratio was better.
