中文摘要:
      研究不同补强剂补强氢化丁腈橡胶（HNBR）在热空气老化过程中的物理性能和动态力学性能变化。结果表明：当补强剂用量均为30份时，甲基丙烯酸镁(MDMA)补强的HNBR硫化胶综合物理性能最好，甲基丙烯酸锌（ZDMA）补强的硫化胶次之，炭黑和白炭黑补强的硫化胶较差；ZDMA和MDMA补强的硫化胶耐老化性能较好；热空气老化后，不同补强剂补强的HNBR硫化胶的损耗因子峰值均有所降低，且老化时间越长，降低幅度越大；炭黑补强的HNBR硫化胶抗湿滑性能最佳，MDMA补强的硫化胶滚动阻力最低。
英文摘要:
      The changes of the physical properties and dynamic mechanical property of HNBR reinforced by different reinforcing agents in the hot air aging process were investigated.The results showed that，when the addition level of reinforcing agent was 30 phr，the HNBR vulcanizates reinforced by magnesium dimethacrylate (MDMA) possessed the best comprehensive physical properties，the vulcanizates reinforced by zinc dimethacrylate(ZDMA) followed，and the vulcanizates reinforced by carbon black and silica showed relatively poor physical properties.The aging resistance of the vulcanizates with ZDMA or MDMA was also better. The peak values of loss factor of the vulcanizates decreased after hot air aging，and as the aging time prolonged，the decrement was higher.The wet skid resistance of the vulcanizates with carbon black was the best，and the rolling resistance of the vulcanizates with MDMA was the lowest.
