The invention discloses a racing car tire tread rubber composite material with high road holding force and a preparation method of the racing car tire tread rubber composite material. The invention belongs to the field of rubber materials and preparation thereof. The invention aims to solve the technical problem that the existing rubber composite material cannot meet the requirements of the racing car tire on the gripping performance and the control performance. The material is prepared from isoprene rubber, first butadiene-isoprene rubber, second butadiene-isoprene rubber, third butadiene-isoprene rubber, sulfur and a functional aid, the molar content of 3, 4-isoprene in the isoprene rubber is 60-80%, the molar content of 1, 2-butadiene in the first butadiene-isoprene rubber and the second butadiene-isoprene rubber is 40-60%, the molar content of 3, 4-isoprene is 40-60%, the molar content of 3, 4-butadiene in the third butadiene-isoprene rubber is 40-60%, and the molar content of 3, 4-butadiene in the third butadiene-isoprene rubber is 40-60%. The molar content of 1, 2-butadiene in the third butadiene-isoprene rubber is 30 to 50 percent, and the molar content of 3, 4-isoprene in the third butadiene-isoprene rubber is 30 to 50 percent.

    本发明公开了一种高抓地力的赛车轮胎胎面橡胶复合材料及其制备方法。本发明属于橡胶材料及其制备领域。本发明的目的是为了解决现有橡胶复合材料无法满足赛车轮胎对于抓地性能和操控性能要求的技术问题。本发明的材料由异戊橡胶、第一丁戊橡胶、第二丁戊橡胶、第三丁戊橡胶、硫磺和功能助剂制备而成,异戊橡胶中3,4‑异戊二烯的摩尔含量为60~80%,第一丁戊橡胶、第二丁戊橡胶中1,2‑丁二烯的摩尔含量为40~60%,3,4‑异戊二烯的摩尔含量为40~60%,第三丁戊橡胶中1,2‑丁二烯的摩尔含量为30~50%,3,4‑异戊二烯的摩尔含量为30~50%。
