| 中文摘要: |
| 研究促进剂TMTD用量对均聚型氯醚橡胶（CO）/共聚型氯醚橡胶（ECO）并用胶硫化特性、物理性能、耐热老化性能和高温压缩永久变形的影响。结果表明，在CO/ECO并用胶中加入促进剂TMTD，胶料的t10延长，t90缩短，硫化胶的耐热老化性能下降；硫化胶的物理性能在促进剂TMTD用量为1份时较好；在合适的二次硫化条件（160 ℃×2 h）下，添加适量的促进剂TMTD，可以减小并用胶的高温压缩永久变形。 |
| 英文摘要: |
| The effect of TMTD on the curing behaviour，physical properties，heat aging property and permanent set at high temperature of CO/ECO was investigated.The results showed that the t10 of CO/ECO blend extended and the t90 reduced，and the heat aging property of its vulcanizate degraded by adding TMTD；the better physical properties of vulcanizate were obtained by using 1 phr of TMTD；and the permanent set at high temperature of vulcanizate after proper post cure（160 ℃×2 h）improved by adding TMTD. |
