| 中文摘要: |
| 介绍硅烷交联三元乙丙橡胶（EPDM）的交联机理、制备方法、交联影响因素、性能表征和应用前景。EPDM的硅烷交联分为硅烷接枝和交联两个阶段，硅烷交联EPDM的制备方法目前主要为两步法和一步法。配方因素、接枝反应温度和时间以及水浴交联温度和时间对硅烷交联EPDM的接枝反应、水解交联反应和性能的影响较大，硅烷交联EPDM的生产工艺目前仍存在较多问题，硅烷交联EPDM的应用研究需要进一步扩展。 |
| 英文摘要: |
| The crosslinking mechanism，preparation methods，crosslinking influencing factors，performance characterization and application prospects of silane crosslinked ethylene-propylene-diene rubber（EPDM） were introduced.The silane crosslinking of EPDM was divided into two stages：silane grafting and crosslinking.At present，the preparation techniques of silane crosslinked EPDM were mainly two-step method and one-step method.The formulation factors，grafting reaction temperature and time，and water bath crosslinking temperature and time had greater impact on the grafting reaction，hydrolysis and crosslinking reaction and properties of silane crosslinked EPDM. There were still many problems in the production process of silane crosslinked EPDM，and the application research of silane crosslinked EPDM should be further expanded. |
