The invention discloses tread rubber with high road holding force and high cold resistance and a preparation method thereof, natural rubber with better comprehensive performance and low temperature resistance of neodymium butadiene rubber are applied, and high-styryl styrene-butadiene rubber with better road holding force, brominated butyl rubber 3745 and brominated butyl reclaimed rubber are used, so that the tread rubber with high road holding force and high cold resistance is obtained. And then super-wear-resistant carbon black and white carbon black with a high specific surface area are added, so that the super-wear-resistant and high-road-holding rubber mixture is obtained. The prepared high road holding formula has the most remarkable characteristics of excellent road holding, and the wear resistance is equivalent to that of tires in the current market. The glass transition temperature of the rubber material is reduced from-20 DEG C to-50 DEG C, and the manufactured tire does not have brittle rupture when used at-40 DEG C. By using the product provided by the invention, the trafficability and low-temperature resistance on a wet and slippery road surface are improved.
本发明公开了一种高抓地力高耐寒胎面胶及其制备方法,通过应用综合性能较优的天然橡胶,以及钕系顺丁橡胶的耐低温性,并用抓地力较好的高苯乙烯基的丁苯橡胶以及溴化丁基橡胶3745与溴化丁基再生胶,再配以超耐磨的炭黑、高比表面积白炭黑从而得到一种超耐磨、高抓地力的橡胶混合物。本发明制备所得高抓地力配方最显著的特点是抓地力优良,耐磨性与现行市场上出现的轮胎相当。胶料玻璃化温度由‑20℃降到‑50℃,所制作的轮胎在‑40℃温度下使用未出现脆裂。使用本发明的产品提高了在湿滑路面的通过性和耐低温性。
