The invention relates to a low-rolling-resistance base rubber material for an all-steel radial tire and a preparation method of the low-rolling-resistance base rubber material, in particular to a method for reducing heat generated by a base formula and optimizing the preparation method of the low-rolling-resistance base rubber material. The low-rolling-resistance base rubber material for the all-steel radial tire comprises the following components in parts by weight: 100 parts of natural rubber, 5-12 parts of carbon black, 35-45 parts of white carbon black, 3.5-4.5 parts of a silane coupling agent, 1.5-3.5 parts of an anti-aging agent, 2-5 parts of zinc oxide, 1-3 parts of stearic acid, 1-3 parts of m-methyl methacrylate, 1-3 parts of sulfur powder, 1-3 parts of an accelerant and 0.1-0.3 part of a scorch retarder. Compared with the prior art, the purpose of reducing heat generated by a base formula is achieved by increasing the parts of the white carbon black and using the m-methyl methacrylate resin, and the rolling resistance is reduced while the abrasion performance of the upper-layer tread is not changed.

    本发明涉及一种全钢子午轮胎低滚阻基部胶料及其制备方法,特别涉及降低基部配方生热,并优化其制备方法,其中全钢子午轮胎低滚阻基部胶料包括以下重量份的各组分:天然胶100份、炭黑5‑12份、白炭黑35‑45份、硅烷偶联剂3.5‑4.5份、防老剂1.5‑3.5份、氧化锌2‑5份、硬脂酸1‑3份、间甲树脂1‑3份、硫磺粉1‑3份、促进剂1‑3份,防焦剂0.1‑0.3份。与现有技术相比,本发明通过增加白炭黑份数以及使用间甲树脂达到降低基部配方生热的目的,在不改变上层胎面的磨耗性能的同时降低滚动阻力。
