摘要
研究了碳纳米管在半钢子午线轮胎胎面中的应用,将预分散的碳纳米管母胶添加在半钢子午线轮胎的胎面配方中,考察了碳纳米管的添加对胎面胶加工性能、物理性能,尤其是导电性能和导热性能的影响,同时对通过此配方生产的轮胎进行了一系列的轮胎性能实验。结果表明:添加碳纳米管母胶CM-100的配方优化后,混炼胶的加工性能有了明显改善;硫化胶的硬度、回弹率、拉伸强度和撕裂强度都有提高;硫化胶的玻璃化转变温度(Tg)不变,保持了良好的抗湿滑性能;损耗因子tanδ值下降,滚动阻力降低;轮胎高速性能优于正常生产的参比轮胎,胎冠表面温度和花纹沟底部温度降低,有助于提高轮胎的耐久性,延长轮胎使用寿命。
The application of carbon nanotube（CNT） masterbatch CM-100 in the tread compound of PCR tire was studied. The effect of CM-100 on the processability and physical properties, especially the thermal and electrical conductivity of the tread compound was studied. CNT compound showed that the hardness, resilience, tensile strength and tear strength were improved. CNT compound has higher thermal conductivity coefficient which is better for tire endurance. There is no difference in tire performances and the temperature at the tread surface and groove bottom decreased, which can prolong the service life of the tire.
