The invention provides a tire tread rubber material containing liquid reclaimed rubber and a preparation method thereof. The invention relates to a tire tread rubber material containing liquid reclaimed rubber. The rubber material is prepared from the following raw materials in parts by weight: 50 to 70 parts of natural rubber, 15 to 30 parts of butadiene styrene rubber, 20 to 40 parts of liquid reclaimed rubber, 25 to 40 parts of carbon black, 1 to 15 parts of white carbon black, 0.2 to 3.0 parts of silane coupling agent, 3.0 to 6.0 parts of anti-aging agent, 3.0 to 5.0 parts of zinc oxide, 1.0 to 3.0 parts of stearic acid, 0.1 to 0.3 part of scorch retarder, 1.0 to 2.0 parts of sulfur and 1.0 to 3.0 parts of accelerant. Firstly, environment-friendly aromatic hydrocarbon oil commonly used in a tire rubber material is used as a softening agent to prepare liquid reclaimed rubber, the liquid reclaimed rubber is added into the tire tread rubber material to serve as a plasticizer, the use amount of carbon black can be reduced, meanwhile, part of functions of liquid rubber can be added, and various indexes of the rubber material can meet the requirements of the tire tread rubber material; and raw materials and processing cost are saved.

    本发明提供一种含液体再生胶的轮胎胎面胶料及其制备方法。一种含液体再生胶的轮胎胎面胶胶料,该胶料由如下重量份的原料组成:天然橡胶50~70份,丁苯橡胶15~30份,液体再生胶20~40份,炭黑25~40份,白炭黑1~15,硅烷偶联剂0.2~3.0,防老剂3.0~6.0份,氧化锌3.0~5.0,硬脂酸1.0~3.0,防焦剂0.1~0.3份,硫磺1.0~2.0份,促进剂1.0~3.0份。先用轮胎胶料常用的环保芳烃油作为软化剂制备液体再生胶,液体再生胶加入轮胎胎面胶胶料中既作为一种增塑剂,又能减少炭黑的用量,同时还能实现添加液体橡胶的部分功能,胶料的各项指标可以满足轮胎胎面胶胶料的要求,节省了原料和加工成本。
