| Abstract: |
| 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. |
