The invention belongs to the technical field of rubber tires, and particularly relates to a tread rubber composition for preparing a high-performance all-steel radial tire, a mixing method of the tread rubber composition and the tire. The tread rubber composition is prepared by mixing the following component raw materials by weight: 100 parts of natural rubber, 1-3 parts of stearic acid, 2.5-7 parts of zinc oxide, 0.8 to 1.6 parts of an accelerant, 0.8 to 1.5 parts of sulfur, 1.5-4 parts of an anti-aging agent, 0.5-1.5 parts of protective wax, 45-57 parts of carbon black, 0.2-1.2 parts of isophthaloyl hydrazine, 0.2-1.2 parts of 1, 6-bis(N, N'-dibenzothiazolyl carbamyl disulfide)-hexane and 0.05-0.20 part of a scorch retarder CTP. The Payne effect and the loss factor tan delta of the rubber material are effectively reduced, meanwhile, the wear resistance of the tread rubber is improved while the loss factor tan delta is further reduced, and the technical problems that the wear resistance is reduced while the rolling resistance is reduced and the like are effectively solved.
本发明属于橡胶轮胎技术领域,具体涉及一种用于制备高性能全钢子午线轮胎胎面胶组合物及其混炼方法和轮胎。该胎面胶组合物由以下重量份的组分原料混炼制得:天然橡胶100份,硬脂酸1~3份,氧化锌2.5~7份,促进剂0.8~1.6份,硫磺0.8~1.5份,防老剂1.5~4份,防护蜡0.5~1.5份,炭黑45~57份,间苯二甲酰肼0.2~1.2,1,6‑双(N,N′‑二苯并噻唑氨基甲酰二硫)‑己烷0.2~1.2防焦剂CTP 0.05~0.20份。本发明有效地的降低胶料的Payne效应和损耗因子tanδ,同时进一步降低损耗因子tanδ的同时提升胎面胶的耐磨性,有效地解决了降低滚阻的同时耐磨性下降的缺陷等技术问题。
