| 中文摘要: |
| 用热空气老化试验、差示扫描量热法和热重分析法研究添加少量氯磺化聚乙烯（CSM）的EPDM硫化胶的热氧稳定性。结果表明：添加CSM的EPDM硫化胶第一分解阶段的活化能低于未添加CSM硫化胶的，而第二分解阶段的活化能却高于未添加CSM硫化胶的。这说明，添加CSM能提高EPDM硫化胶耐长期热氧老化性能，但对硫化胶早期的热分解起加速作用。 |
| 英文摘要: |
| The influence of low level of CSM on the thermo-oxidative stability of EPDM vulcanizate was investigated by hot air aging test，DSC and TG. The results showed that the long-term aging property of EPDM vulcanizate was improved by adding small amount of CSM，but its initial thermal decomposition was accelerated. |
