The invention discloses an all-steel truck tire radial tire tread compound and a preparation method thereof. The tread compound comprises raw materials such as natural rubber, carbon fiber-integrated rubber and auxiliary materials; the carbon fiber-integrated rubber is composed of carbon fibers dispersed in F-SIB/D Formed in a rubber matrix; in the F-SIB/D, F is a polar end-blocking group; SIB is a ternary random copolymer of styrene, butadiene and isoprene; S is a styrene unit, and I is an isoprene unit, B is a butadiene unit, and D is a divinylbenzene branched unit randomly distributed in the SIB ternary random copolymer. The sidewall vulcanizate composed of carbon fiber-integrated rubber and natural rubber exhibits good low compression heat generation, cutting resistance, tear resistance, high resilience, fatigue resistance, high tensile stress, no cracking and anti-aging characteristics. Suitable for all-weather all-steel truck tires, and can drive safely and lastingly, not easy to blow out. |
