| 中文摘要: |
| 采用机械共混法制备超细石墨/氢化丁腈橡胶（HNBR）复合材料，研究超细石墨用量对超细石墨/HNBR复合材料性能的影响。结果表明，超细石墨用量对复合材料的硫化特性影响不大；随着超细石墨用量的增大，复合材料的邵尔A型硬度变化不大，100％定伸应力增大，拉伸强度和拉断伸长率减小，撕裂强度有所降低，体积磨耗量先增大后减小；当超细石墨用量达到40份时，复合材料的摩擦因数明显减小。 |

| A submicrometer-graphite/HNBR composite was prepared by mechanical blending method，and the effects of the addition level of submicrometer-graphite on the properties of the composite were investigated.The results showed that the addition level of submicrometer-graphite had little effect on the curing behavior of the composite；the Shore A hardness of the composite changed a little，the tensile strength，elongation at break and tear strength decreased，and the abrasion loss increased at first and then decreased as the addition level of submicrometer-graphite increased；the friction coefficient of this material decreased significantly when 40 phr submicrometer-graphite was used. |
