The invention relates to the technical field of tire rubber, in particular to a four-season all-steel ice and snow tire tread rubber composition. The composition comprises the following steps, by weight, after mixing: 10-30 parts of natural rubber, 10-35 parts of liquid rubber, 65-80 parts of functionalized solution polymerized styrene-butadiene rubber, 5-25 parts of carbon black, 20-55 parts of white carbon black with a low specific surface area, 4.0 -12.0 parts of a silane coupling agent ranges, 1.5-3.0 parts of white carbon black dispersing agent, 2.0-5.0 parts of zinc oxide, 1.0-3.0 partsof stearic acid, 1.0-3.0 parts of an anti-aging agent 4020, 1.5-2.5 parts of an anti-aging agent RD, 1.0-4.0 parts of rubber protective wax, 1.5-2.5 parts of sulfur S-80, 1.0-3.5 parts of tear-resistant resin, 1.0-2.5 parts of an accelerant NS-80 and 0-0.5 part of an accelerant DPG-80. The tire tread produced by the invention not only has excellent snowfield grip on a snowfield pavement, but alsokeeps excellent grip on an all-ice pavement, and has excellent rolling resistance, wet skid resistance and wear resistance.

    本发明涉及轮胎橡胶技术领域,具体地说是一种四季型全钢冰雪地轮胎胎面橡胶组合物,包含以下的组分按重量份数混炼构成:天然橡胶10~30,液体橡胶10~35,功能化溶聚丁苯橡胶65~80,炭黑5~25,低比表面积白炭黑20~55,硅烷偶联剂4.0~12.0,白炭黑分散剂1.5‑3.0,氧化锌2.0~5.0,硬脂酸1.0~3.0,防老剂4020 1.0~3.0,防老剂RD 1.5~2.5,橡胶防护蜡1.0~4.0,硫磺S‑80 1.5~2.5,抗撕裂树脂1.0~3.5,促进剂NS‑80 1.0~2.5,促进剂DPG‑80 0~0.5。本发明所生产的轮胎胎面不仅仅在雪地路面有优异的雪地抓着力,在全冰路面抓着力仍保持优良的抓地力,而且具有优异的滚动阻力性能、抗湿滑性能和耐磨耗性能。
