摘　　要：为了进一步改善车辆轮胎胎面的力学性能、耐磨性能及加工与硫化性能,结合具有优良导热、导电、力学性能的石墨烯材料,采用分子链滑动模型分析了石墨烯/轮胎胎面橡胶补强机理,研究了不同石墨烯含量对轮胎复合胎面性能的影响规律。研究表明,轮胎胎面橡胶的硫化性能、抗拉强度、撕裂强度、耐磨耗指数、耐疲劳次数等随石墨烯含量的增加呈现先增加而后减少的趋势,邵尔硬度呈现先下降而后上升的趋势,轮胎胎面橡胶耐冲击回弹性逐渐下降的趋势;石墨烯含量在7%左右时,车辆轮胎胎面的力学性能、耐磨性能及耐疲劳能力较高,轮胎胎面橡胶的强化效果较为理想。In order to further improve the mechanical properties,wear resistance,processing and vulcanization properties of vehicle tire tread,combined with graphene materials with excellent thermal conductivity,conductivity and mechanical properties,the molecular chain sliding model was used to analyze the reinforcement mechanism of graphene/tire tread rubber,and the influence of different graphene contents on the performance of tire composite tread was studied.Research showed that the vulcanization performance,tensile strength,tear strength,wear resistance index and fatigue resistance of tire tread rubber showed a trend of first increasing and then decreasing with the increase of graphene content.The Shore hardness showed a trend of first decreasing and then increasing,and the impact resilience of tire tread rubber gradually decreased,when the graphene content was around 7%,the mechanical properties,wear resistance and fatigue resistance of vehicle tire tread were higher,and the strengthening effect of tire tread rubber was more ideal.
