| 中文摘要: |
| 采用伊蒙粘土替代部分炭黑，研究伊蒙粘土用量对伊蒙粘土/炭黑/天然橡胶复合材料硫化特性、物理性能、动态力学性能和导热性能的影响。结果表明：随着伊蒙粘土用量增大，混炼胶的Payne效应减弱，最大转矩减小，正硫化时间缩短；硫化胶的耐热老化性能、气密性、抗冲击性能提高；添加5和7份伊蒙粘土的硫化胶物理性能和耐磨性能与未添加伊蒙粘土的硫化胶相当，且明显好于添加10和15份伊蒙粘土的硫化胶；伊蒙粘土可明显提高硫化胶的抗湿滑性能、减小滚动阻力。 |
| 英文摘要: |
| 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. |
