| 中文摘要: |
| 研究不同硫化体系和防护体系对T2级耐热输送带覆盖胶耐热老化性能的影响。结果表明：有效硫化体系硫化胶的耐热老化性能优于过氧化物硫化体系硫化胶；采用反应型防老剂防护体系的硫化胶耐热老化性能较好；与现有生产配方硫化胶相比，耐热防老剂A（苯胺类反应型防老剂）/防老剂RD（或4020）体系硫化胶的耐热老化性能较好，尤其在高温长时下表现突出。 |
| 英文摘要: |
| The effect of different curing systems and protecting systems on the heat aging resistance of cover compound of T2 heat resistant conveyor belt was investigated.The results showed that，the heat aging resistance of the vulcanizates with efficient curing system was better than that with peroxide curing system.The heat aging resistance of the vulcanizates with the reactive antioxidant protecting system was better.Compared with existing product，the heat aging resistance of the vulcanizates with antioxidant A（aniline reactive antioxidant）/antioxidant RD（or 4020）system was better，particularly under the condition of high temperature for long periods. |
