| 中文摘要: |
| 采用橡胶加工分析仪（RPA）对不同牌号氢化丁腈橡胶（HNBR）混炼胶和硫化胶进行性能表征，并与其他测试仪器进行比较。结果表明：HNBR混炼胶的硫化速率和填料分散性以及硫化胶的力学性能随HNBR门尼粘度的增大而提高；硫化胶的耐老化性能随HNBR氢化度的提高而提高；硫化胶的损耗因子和玻璃化温度随HNBR丙烯腈含量的增大而分别增大和提高。使用RPA可以获得通常需要无转子硫化仪、万能材料试验机、扫描电子显微镜和动态力学分析仪等多台仪器测试的结果，即利用RPA可以较方便地对不同牌号HNBR胶料进行配方调控以获得预期效果。 |
| 英文摘要: |
| The properties of different grades of hydrogenated nitrile rubber(HNBR) compounds and vulcanizates were characterized by rubber processing analyzer(RPA)，and compared with other testing instruments. The results showed that the curing rate and filler dispersion of HNBR compound and mechanical properties of HNBR vulcanizate increased with the increase of the Mooney viscosity of HNBR. The aging resistance of HNBR vulcanizate increased with the increase of the hydrogenation degree of HNBR. The loss factor and glass transition temperature of HNBR vulcanizate increased with the increase of the acrylonitrile content of HNBR. RPA could be used to obtain the test results that usually required multiple instruments，such as rotorless vulcanizer，universal material testing machine，scanning electron microscope and dynamic mechanical analyzer. Therefore，RPA could be used to conveniently regulate the compound formulation of HNBR with different grades to obtain the expected results. |
