The invention provides a preparation method of a low-rolling-resistance rubber material, and relates to the technical field of tire rubber. The preparation method of the low-rolling-resistance rubber material comprises the following steps: S1, performing one-stage or multi-stage mixing on a rubber material in a constant-temperature mixing manner to obtain a rubber master batch; and S2, mixing the rubber master batch obtained in the step S1, a vulcanizing agent and an accelerant, and mixing to obtain the final mixed rubber. Silicon dioxide is added into a rubber material formula, meanwhile, a saturated and unsaturated fatty acid zinc soap mixture is adopted as a dispersing auxiliary agent of a rubber material, a constant-temperature mixing mode is combined, final mixing rubber with reduced rolling resistance is obtained through sulfur addition, and the rolling resistance is reduced under the condition that rubber components and the silicon dioxide structure are not changed. According to the invention, the dispersibility of silicon dioxide in a rubber material can be increased, the processability of rubber is improved, the wear resistance, the grip property and the like of a tire are greatly improved, the heat generation is greatly reduced, the cost is relatively low, and industrial application is facilitated.

    本发明提供一种低滚阻胶料的制备方法,涉及轮胎橡胶技术领域。该一种低滚阻胶料的制备方法,包括S1、将橡胶物料采用恒温混炼方式进行一段或多段混炼,得到母胶;S2、将S1步骤中得到的母胶、硫化剂与促进剂混合后进行混炼,得到终炼胶。通过在胶料配方中添加二氧化硅,同时采用饱和及不饱和脂肪酸锌皂混合物作为橡胶物料的分散助剂,并结合恒温混炼的混炼方式,经加硫得到滚动阻力降低的终炼胶,在不改变橡胶组分和二氧化硅结构的情况下,本发明可增加二氧化硅在胶料中的分散性,提升了橡胶加工性,同时使轮胎的耐磨性、抓地性等均大幅提升,生热大大降低,并且本发明成本较低,利于工业化应用。
