The invention relates to a rubber composition for tread rubber of a truck tire. The rubber composition comprises the following components in parts by weight: 100 parts of rubber, 40-100 parts of carbon black, 4-40 parts of a softening agent, 2-20 parts of a tackifier, 0.04-1.2 parts of a peroxide curing agent and 0.5-2 parts of a sulfur curing agent. Compared with the prior art, the rubber composition disclosed by the invention has the advantages that the wear resistance of a tread rubber formula is improved, and meanwhile, the rubber composition has the balance of low dynamic heat generation, low rolling resistance and wet skid resistance and is used for forming a tire tread for a lorry.

    本发明涉及一种用于载重轮胎胎面胶的橡胶组合物,包括以下重量份数的组分:橡胶100份,炭黑40‑100份,软化剂4‑40份,增粘剂2‑20份,过氧化物固化剂0.04‑1.2份,硫磺固化剂0.5‑2份。与现有技术相比,本发明的橡胶组合物提高了胎面胶配方的耐磨性能,同时兼有低动态生热、低滚动阻力、抗湿滑性的平衡的用于形成载重汽车用轮胎胎面。
