中文摘要:
      研究碳纳米管对越野子午线轮胎胎面胶性能的影响。结果表明:随着碳纳米管用量增大,胎面胶的 ts1t90略有缩短,硬度、300%定伸应力、拉伸强度和撕裂强度提高,耐热空气老化和耐臭氧老化性能没有明显变化,生热提高;碳纳米管用量为1份的胎面胶具有较好的物理性能和耐磨性能,较低的生热,用其制备的胎面胶生产的越野子午线轮胎耐久性能较好。
英文摘要:
      The influence of carbon nanotubes on the properties of the tread compound of cross-country radial tire was investigated. The results showed that,with the amount of carbon nanotubes increasing,the scorch time ts1 and optimum cure time t90 of the compound were shortened,Shore A hardness,modulus at 300% elongation,tensile strength and tear strength were improved,heat air aging resistance and ozone aging resistance changed little,and heat build-up increased. When carbon nanotubes amount was 1 phr,the physical properties and wear resistance of the compound were good,and heat build-up was low. The endurance performance of the cross-country radial tire was improved by adding 1 phr carbon nanotubes in the tread compound.
