| 采用石墨烯和白炭黑替代部分炭黑，研究填料并用对高频减振橡胶材料[天然橡胶（NR）/顺丁橡胶（BR）（并用比为70/30）硫化胶]物理性能、压缩永久变形、耐磨性能和高频下动静刚度比的影响。结果表明：采用石墨烯替代部分炭黑N774，NR/BR硫化胶的拉伸强度增大，动静刚度比减小，当炭黑N774/石墨烯并用比为20/1.5时，硫化胶的物理性能良好，动静刚度比最小；在炭黑N774/石墨烯并用比为20/1.5的基础上采用10份白炭黑等量替代炭黑N774，即炭黑N774/石墨烯/白炭黑用量比为10/1.5/10的NR/BR硫化胶的压缩永久变形和动静刚度比最小，耐磨性能良好。 |

| Replacing part of carbon black with graphene and silica，the effects of filler blending on the physical properties，compression set，wear resistance and dynamic/static stiffness ratio of high-frequency damping rubber materials[natural rubber（NR）/butadiene rubber（BR）（blending ratio of 70/30） vulcanizates] were studied.The results showed that graphene was used to replace partial carbon black N774，the tensile strength of NR/BR vulcanizate was increased，and the dynamic/static stiffness ratio was decreased.When the carbon black N774/graphene blending ratio was 20/1.5，the physical properties of the vulcanizate were good，and the dynamic/static stiffness ratio was the lowest.Based on a carbon black N774/graphene blending ratio of 20/1.5，10 phr silica was used to replace equal parts of carbon black N774，the compression set and dynamic/static stiffness ratio of NR/BR vulcanizate with carbon black N774/graphene/silica blending ratio of 10/1.5/10 were the lowest，and the wear resistance was good. |
