The invention provides an anti-aging tire rubber composition and an application thereof; the rubber composition comprises 100 parts by mass of a rubber component comprising 90-100 parts by mass of natural rubber and 0-10 parts by mass of butadiene rubber, 75 to 88 parts by mass of carbon black, 5-10 parts by mass of a processing aid, 15-25 parts by mass of butadiene-styrene copolymer resin, and 4-6 parts by mass of a vulcanizing agent, wherein the mass content of a styrene structure in the butadiene-styrene copolymer resin is greater than or equal to 83%. The formula is simple, all the components act together in a certain proportion, the tire seam allowance protective rubber can be endowed with better aging resistance and hardness retention rate under the high-temperature condition, it isguaranteed that the rigidity of a vehicle can be maintained in the running process, and then the safety coefficient of a tire is increased. In addition, the processing workability of the formula is good.

    本发明提供了一种耐老化轮胎橡胶组合物及其应用,所述橡胶组合物包括:100质量份的橡胶组分,所述橡胶组分包括90~100份的天然橡胶和0~10的顺丁橡胶;75~88质量份的炭黑;5~10质量份的加工助剂;15~25质量份的丁二烯‑苯乙烯共聚树脂,所述丁二烯‑苯乙烯共聚物树脂中苯乙烯结构质量含量≥83%;4~6质量份的加硫剂。本发明配方简单,各组分在一定配比下共同作用,可以赋予轮胎子口护胶更好的耐老化性能和高温条件下的硬度保持率,保证车辆行驶中能维持其刚性,进而提升轮胎安全系数。此外,本发明配方的加工作业性较好。
