| Abstract: |
| By using Yimeng clay to replace some carbon black，the effect of the addition level of Yimeng clay on the vulcanization characteristics，physical properties，dynamic mechanical properties and thermal conductivity of Yimeng clay/carbon black/natural rubber（NR） composites was investigated. The results showed that，with the addition level of Yimeng clay increasing，the Payne effect of the compound was weakened，the maximum torque was reduced，the optimum cure time was shortened，and the thermal aging resistance，air tightness and impact resistance of the vulcanizate were improved. Compared with the vulcanizate without Yimeng clay，the physical properties and wear resistance of the vulcanizate with 5 or 7 phr Yimeng clay were quite similar，and obviously better than that with 10 or 15 phr Yimeng clay. Yimeng clay could significantly improve the wet skid resistance of the vulcanizate and reduce the rolling resistance. |
