The invention belongs to the technical field of rubber, and particularly relates to high-wear-resistance and high-tear-resistance tire tread rubber and a preparation method thereof. The high-wear-resistance and high-tear-resistance tire tread rubber is prepared from natural rubber, mixed powder, zinc oxide, an anti-aging agent, a dispersing agent, an accelerant, a scorch retarder and sulfur, the mixed powder is mainly prepared from graphene, carbon black and high-specific-surface white carbon black, the graphene, the carbon black and the high-specific-surface white carbon black are pretreated to obtain the mixed powder, and then the mixed powder is added into the tire tread rubber, so that the problems that the graphene, the N110 series carbon black and the high-specific-surface white carbon black are poor in dispersity in rubber and poor in processing technology are solved, and the service life of the tire tread rubber is prolonged. And the wear resistance, tear resistance and other mechanical properties of the tire tread rubber can be greatly improved. Meanwhile, the tread rubber is simple in preparation process, relatively low in cost and suitable for industrial production.
本发明属于橡胶技术领域,具体涉及一种高耐磨、高抗撕轮胎胎面胶及其制备方法。所述高耐磨、高抗撕轮胎胎面胶由天然橡胶、混合粉末、氧化锌、防老剂、分散剂、促进剂、防焦剂、硫磺制得;所述混合粉末主要由石墨烯、炭黑和高比表白炭黑制得,本发明通过对石墨烯、炭黑和高比表白炭黑进行预处理得到混合粉末,然后加入到轮胎胎面胶中,不仅解决了石墨烯、N110系炭黑、高比表白炭黑在橡胶中分散性差、加工工艺差的问题,还可大幅提高轮胎胎面胶的耐磨性和抗撕裂性等力学性能。同时,所述胎面胶的制备工艺简单,成本较低,适用于工业化生产。
