The invention relates to the technical field of rubber, in particular to a low-rolling-resistance wet-skid-resistant truck tire tread rubber composition which comprises the following components in parts by weight: 25-35 parts of natural rubber, 30-40 parts of solution polymerized styrene-butadiene rubber, 20-30 parts of neodymium butadiene rubber, 20-30 parts of high-abrasion-resistance carbon black, 40-60 parts of pyrolytic carbon black, 5-10 parts of aromatic hydrocarbon oil, 3-6 parts of nano zinc oxide, 1-3 parts of stearic acid, 2-4 parts of a p-phenylenediamine anti-aging agent and 1-3 parts of a ketoamine anti-aging agent. According to the invention, the solution polymerized styrene-butadiene rubber composition and the neodymium butadiene rubber composition are added, so that the low rolling resistance and the wet skid resistance of a tire tread are improved, and meanwhile, by adjusting a raw rubber system, an anti-aging system and a filling system, the anti-aging performance and the flexing performance of the rubber composition meet the dynamic performance requirements.

    本发明涉及橡胶技术领域,低滚动阻力、抗湿滑载重轮胎胎面橡胶组合物,以重量份计含有:天然橡胶25‑35,溶聚丁苯橡胶30‑40,钕系顺丁橡胶20‑30,高耐磨炭黑20‑30,热解炭黑炭黑40‑60芳烃油5‑10,纳米氧化锌3‑6,硬脂酸1‑3,对苯二胺防老剂2‑4,酮胺防老剂1‑3,微晶蜡1‑2,硫磺0.5‑1.5,次磺酰胺促进剂1‑2,本发明通过填加溶聚丁苯、钕系顺丁橡胶组合物的应用来提升载轮胎胎面低滚动阻力、抗湿滑性能,同时通过调整生胶体系、防老体系、填充体系使橡胶组合物的耐老化性能、屈挠性能满足动态性能要求。
