摘　　要：为了进一步提高车辆轮胎的力学性能、耐磨性能及冰路面抗滑性能,将石墨烯作为车辆轮胎胎面增强体材料,进行了石墨烯增强车辆轮胎胎面配方及制备工艺设计,对石墨烯不同含量下的胎面拉伸强度、撕裂强度、100%定伸应力、300%定伸应力、耐磨指数等物理机械力学性能进行了测试,并对石墨烯强化后的车辆轮胎进行了冰路面抗滑性能实车试验,获得了不同质量分数下的石墨烯增强材料对车辆轮胎胎面的性能影响规律,并应用分子链滑动理论对石墨烯强化车辆轮胎胎面橡胶机理进行了分析.测试及分析结果表明:当石墨烯质量分数约为7%左右,对车辆轮胎胎面橡胶的性能强化效果较为理想,其主要物理机械力学性能指标良好,车辆轮胎的耐磨性能和抗滑性能得到了较大提高.In order to improve the mechanical properties,wear resistance and skid resistance of the vehicle tire,the formulation and preparation technology of graphene reinforced vehicle tire tread were dsigned.The tensile strength,tear strength,100%extension stress,300%extension stress,wear resistance index and other physical and mechanical properties of tread were tested at different contents of grapheme.Furthermore,the test on the skid resistance of the vehicle tire after graphene strengthening was carried out.The performance effect laws of the graphene reinforcement on vehicle tire tread were obtained,and the mechanism of graphene reinforced tread rubber was analyzed by molecular chain sliding theory.The results of testing and analysis show that:the reinforcement effect on tread rubber is ideal when the graphene percentage of quality is about 7%.Moreover,the main physical and mechanical performance indexes are good and the wear resistance performance and skid resistance performance of the vehicle tire are greatly improved.
