The invention relates to the technical field of tire rubber manufacturing, and discloses a wear-resistant and high-temperature-resistant tread rubber composition and a mixing method thereof.The rubber composition is prepared from, by weight, 65-80 parts of rubber, 40-60 parts of filler A, 3-6 parts of an activating agent, 2-4 parts of a vulcanizing agent, 2-5 parts of an anti-aging agent and 0.5-1.5 parts of tear-resistant resin through mixing, 15-45 parts of a nano reinforced composite material and 0.5-2 parts of microcrystalline wax; the nano reinforced composite material is prepared by mixing butadiene rubber, a filler B, organic sulfide and dihydrazide. Through non-homogeneous distribution of the filler, the nano reinforced composite material can absorb a large amount of energy in the stretching process, and the high temperature resistance and wear resistance of the tread rubber composition can be obviously improved.

    本发明涉及轮胎橡胶制造技术领域,公开了一种耐磨耐高温胎面橡胶组合物及其混炼方法,所述橡胶组合物按重量份计包括以下组分的原料混炼制备得到:橡胶65‑80份,填料A 40‑60份,活化剂3‑6份,硫化剂2‑4份,防老剂2‑5份,抗撕裂树脂0.5‑1.5份,纳米增强复合材料15‑45份,微晶蜡0.5‑2份;纳米增强复合材料由顺丁橡胶、填料B、有机硫化物和二酰肼混炼制备得到。本发明通过填料的不均相分布,纳米增强复合材料在拉伸的过程中能够大量的吸收能量,可以明显提升胎面橡胶组合物的耐高温性能和耐磨性能。
