| 中文摘要: |
| 研究了甲基丙烯酸锌（ZDMA）/NBR纳米复合材料的静态和动态力学性能，并与炭黑N220/NBR体系进行了对比。试验结果表明，ZDMA/NBR胶料的硫化时间应比正硫化时间适当延长。与炭黑N220/NBR体系相比，ZDMA/NBR硫化胶的邵尔A型硬度、拉伸强度、扯断伸长率、100%定伸应力和撕裂强度均较高，且具有更好的耐热空气老化性能和耐热油性能；ZDMA/NBR胶料的贮存模量较高，动态压缩生热较小，但动态压缩永久变形较大。 |

| The static and dynamic properties of ZDMA/NBR nano-composite were investigated and compared to those of C.B. N220/NBR system.The test results showed that the higher Shore A hardness，tensile strength，elongation at break，modulus at 100% elongation and tear strength，better hot air aging property and hot oil resistance of ZDMA/NBR vulcanizate were obtained when compared to those of C.B. N220/NBR vulcanizate；and ZDMA/NBR vulcanizate possessed higher storage modulus and lower dy namic compression heat build-up，but larger dynamic compression set. |
