| 中文摘要: |
| 用N，N′-间苯基双马来酰亚胺（MPBM）作助交联剂、过氧化二异丙苯作硫化剂制备四丙氟橡胶胶料，用热重法研究MPBM对四丙氟橡胶胶料热稳定性能的影响。结果表明：与未添加MPBM的胶料相比，添加MPBM胶料的热分解温度提高，热分解表观活化能（E）增大；随着MPBM用量增大，胶料的热分解温度增幅减小或热分解温度趋于稳定，热分解表观活化能先增大后减小；MPBM能提高胶料的热稳定性，当MPBM用量为10份时，胶料热稳定性能最好。 |
| 英文摘要: |
| The fluororubber based on copolymer of tetrafluoroethylene and propylene was cured by curing agent dicumyl peroxide and auxiliary crosslinking agent N， N′-m-phenyl bismaleimide (MPBM)， and the thermal stability of the vulcanizate was studied by thermalgravimetric analysis method. The experimental results showed that， with MPBM， the thermal decomposition temperature and activation energy of the fluororubber vulcanizate increased. With the increase of MPBM amount， the increase of the decomposition temperature slowed down and it approached a plateau value； meanwhile， the activation energy increased at first and then decreased. The optimum addition level of MPBM was 10 phr. |
