The invention provides cutting-resistant and low-heat-generation mining tire tread rubber, a preparation method thereof and a mining tire. According to the cutting-resistant and low-heat-generation mining tire tread rubber disclosed by the invention, the butadiene styrene rubber is matched with the ultrahigh white carbon black and the silane coupling agent to realize synchronous improvement of cutting resistance and low-heat-generation performance; the dosage of the silane coupling agent is controlled to be 7-8% of the dosage of the white carbon black through theoretical calculation and multiple tests, so that good comprehensive performance can be obtained; novel low-hysteresis high-reinforcement N129 carbon black is adopted to balance the heat generation performance, the product of strength and elongation of the rubber material is improved, and the cutting resistance is further improved; the processing performance is improved by adopting the low-Mooney high-strength reclaimed rubber, and the formula design cost is further reduced; the novel mining tire tread formula with cutting resistance and low heat generation comprehensive performance is invented, so that the comprehensive adaptability of a tire is greatly improved, the early failure rate of the tire is reduced, the service life is prolonged, and the safety of the tire is improved.

    本发明提供了一种耐切割、低生热矿用轮胎胎面胶及其制备方法、矿用轮胎。本发明的耐切割、低生热矿用轮胎胎面胶,采用丁苯橡胶配合超高白炭黑及硅烷偶联剂的组合方式,来实现耐切割、低生热性能的同步提升;硅烷偶联剂的用量经过理论计算,及多次试验论证,控制在白炭黑用量的7~8%可以得到很好的综合性能;采用新型低滞后高补强N129炭黑来平衡生热性能,提升胶料的强伸积,进一步提升抗切割性能;采用低门尼高强力再生胶来改善加工性能,并进一步降低了配方设计成本;发明了一种新的具备耐切割、低生热综合性能的矿用轮胎胎面配方,使轮胎的综合适应性能大幅度提高,降低了轮胎的早期故障率,从而延长了使用寿命,并提高了轮胎的安全性。
