The invention discloses a tire tread rubber composition and a preparation method thereof, and belongs to the technical field of tires. The tire tread rubber composition is prepared from the following raw material components in parts by weight: 45 to 60 parts of first rubber, 55 to 75 parts of second rubber, 25 to 35 parts of carbon black, 8 to 12 parts of modified alkyl phenolic resin, 5 to 8 parts of an adhesive RA, 3 to 5 parts of an anti-aging agent, 1 to 3 parts of a vulcanizing agent and 0.5 to 2 parts of an accelerant, the first rubber is natural rubber SPR10 or natural rubber SVR3L, the second rubber is one or two of solution polymerized styrene-butadiene rubber, isoprene rubber and brominated butyl rubber, and the weight ratio of the first rubber to the second rubber is (0.8-1): 1. According to the tire tread rubber composition and the preparation method thereof, the modified alkyl phenolic resin is introduced into the rubber composition, so that the bonding performance between rubber and a steel wire cord is enhanced, meanwhile, the blooming phenomenon is avoided, and the tire durability is improved.

    本申请公开了一种轮胎胎面橡胶组合物及其制备方法,属于轮胎技术领域。一种轮胎胎面橡胶组合物,按重量份数计,包括如下原料组分:45‑60份第一橡胶,55‑75份第二橡胶,25‑35份炭黑,8‑12份改性烷基酚醛树脂,5‑8份粘合剂RA,3‑5份防老剂,1‑3份硫化剂,0.5‑2份促进剂;所述第一橡胶为天然橡胶SPR10或天然橡胶SVR3L,所述第二橡胶为溶聚丁苯橡胶、异戊橡胶、溴化丁基橡胶中的一种或两种,所述第一橡胶与所述第二橡胶的重量比为(0.8‑1):1。该轮胎胎面橡胶组合物及其制备方法通过在橡胶组合物中引入改性烷基酚醛树脂,增强橡胶与钢丝帘线之间的粘合性能,同时避免发生喷霜现象,提高轮胎耐久性。
