The invention provides a tread rubber composition and a preparation method thereof and a truck radial tire, belongs to the field of tire processing, and aims to solve the problems of poor wear resistance, low hysteresis loss and other related properties of an all-steel truck radial tire. The tread rubber composition comprises the following components in parts by mass: 100 parts of a matrix rubber, 20-30 parts of carbon black, 20-30 parts of white carbon black, 2-4 parts of a silane coupling agent, 3-5 parts of an anti-aging agent, 4-7 parts of an active agent, 1-3 parts of a vulcanizing agent and 3-5 parts of an accelerant. The tread rubber composition provided by the invention has higher wear resistance, low hysteresis loss and lower heat generation, and can be applied to truck radial tires, so that the truck radial tires have high wear resistance and low hysteresis performance.

    本发明提出一种胎面橡胶组合物及其制备方法、载重子午线轮胎,属于轮胎加工领域,能够解决全钢载重子午线轮胎在耐磨性、低滞后损失等相关性能方面不佳的问题。本发明胎面橡胶组合物,按照质量份计包括下列组分:基体橡胶100份,炭黑20‑30份,白炭黑20‑30份,硅烷偶联剂2‑4份,防老剂3‑5份,活性剂4‑7份,硫化剂1‑3份,促进剂3‑5份。本发明胎面橡胶组合物具有更高的耐磨性能、低的滞后损失,较低的生热,能够应用于载重子午线轮胎,使其具有高耐磨低滞后性能。
