| 中文摘要: |
| 研究了不同硫化体系以及其它配方因素对IIR硫化胶耐热老化性能的影响。研究结果表明:经过160 ℃×24 h热老化后，树脂硫化IIR的力学性能保持率比硫黄硫化和硫给予体硫化IIR高；树脂用量为5～10份、氯化锡用量为5～9份、氧化锌的用量为5份时，IIR硫化胶的耐热老化性能最好；采用ISAF/GPF并用以及添加蓖麻油，可以获得较好的耐热老化性能。 |
| 英文摘要: |
| The effect of different curing systems and other ingredients on the heat aging properties of IIR vulcanizate was investigated.The test results showed that the physical property retention of IIR cured with resin after 160 ℃×24 h heat aging was superior to those cured with sulfur or sulfur donor；the optimum heat aging properties of IIRvulcanizate were obtained when 5～10 phr of resin，5～9 phr of SnCl2 and 5 phr of ZnO were used；and the heat aging properties were further improved by adding ISAF/GPF and ricinus oil. |
