| 中文摘要: |
| ZSC是甲基丙烯酸锌（ZDMA）接枝改性氢化丁腈橡胶（HNBR）制备的一种新型高强度聚合物。为了提高HNBR胶料在高温下的物理性能，采用机械共混法制备ZSC/HNBR并用胶，通过调整ZSC/HNBR并用比考察ZDMA含量对ZSC/HNBR并用胶性能的影响。结果表明：与纯HNBR硫化胶相比，ZSC/HNBR并用胶的硫化特性、常温及高温物理性能较好；ZDMA含量对ZSC/HNBR并用胶物理性能的影响显著，当ZSC/HNBR并用比为50/50（ZDMA质量分数为0. 245 9）时，硫化胶综合常温物理性能较佳；当ZSC/HNBR并用比为85/15（ZDMA质量分数为0. 423 7）时，硫化胶综合高温物理性能较佳。 |
| 英文摘要: |
| ZSC is a new type of high strength polymer prepared by grafting modified hydrogenated nitrile rubber（HNBR）with zinc methacrylate（ZDMA）.In order to improve the physical properties of HNBR compound at high temperature，ZSC/HNBR blends were prepared by mechanical blending.The effects of ZDMA content on the properties of ZSC/HNBR blends were investigated by adjusting the ZSC/HNBR ratio. The results showed that，ZSC/HNBR blends had better curing characteristics，physical properties at room temperature and high temperature than pure HNBR vulcanizates，and the content of ZDMA had a significant effect on the physical properties of ZSC/HNBR blends.When the blend ratio of ZSC/HNBR was 50/50（the mass fraction of ZDMA was 0.245 9），the comprehensive physical property of the vulcanizate at room temperature was the best.When ZSC/HNBR blend ratio was 85/15（ZDMA mass fraction was 0.423 7）， the comprehensive physical property of the vulcanizate at high temperature was the best. |
