| Abstract: |
| 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. |
