The invention belongs to the technical field of automobile tires, particularly relates to a low-rolling-resistance tread formula, and provides the following scheme aiming at the problems that an existing low-rolling-resistance tread is poor in performance in all aspects, waste tires cannot be recycled, resources are wasted, and sustainable development cannot be met. The formula comprises the following important components: waste tire, carbon black, natural rubber, silica gel, a plasticizer, a vulcanizing agent, a silane coupling agent, an anti-aging agent, an antioxidant, a flexibilizer, a catalyst, a defoaming agent, environment-friendly oil and wear-resistant and pressure-resistant components, wherein the wear-resistant and pressure-resistant components comprise polyvinyl chloride, silicon carbide, ferroboron and silicon-calcium-barium. According to the formula, the waste tires can be recycled for the second time, resources can be saved, and the sustainable development requirement can be met; the natural rubber, the silica gel and the plasticizer can improve the toughness of the low-rolling-resistance tread; the wear-resistant and pressure-resistant components comprise polyvinyl chloride, silicon carbide, ferroboron and silicon-calcium-barium so that the wear resistance of the low-rolling-resistance tread can be improved.
本发明属于汽车轮胎技术领域,尤其是一种低滚阻胎面配方,针对现有的低滚阻轮胎的胎面各方面性能差,不能对废胎进行重复利用,浪费资源,不能满足可持续发展的问题,现提出如下方案,其包括以下重要成分:废胎、炭黑、天然橡胶、硅胶、增塑剂、硫化剂、硅烷偶联剂、防老剂、抗氧剂、增韧剂、催发剂、消泡剂、环保油、耐磨压成分,耐磨压成分包括:聚氯乙烯、碳化硅、硼铁、硅钙钡。本发明可以对废胎进行二次回收利用,可以节约资源,满足可持续发展需求;设置的天然橡胶、硅胶、增塑剂可以提高低滚阻胎面的韧性;设置的耐磨压成分包括:聚氯乙烯、碳化硅、硼铁、硅钙钡,可以提高低滚阻胎面的耐磨性能。
