Abstract

The invention provides radial tire crown rubber for a high-speed passenger car, and belongs to the technical field of tire manufacture and particularly relates to automotive tire crown rubber. The automotive tire crown rubber comprises the following components: solution polymerized styrene-butadiene rubber, butadiene rubber, white carbon black, carbon black, sulfur, aromatic hydrocarbon, nano-zinc oxide antiager, high abrasion furnace black, silane coupling agent, scorch retarder, gas carbon black, accelerant, stearic acid and anti-reversion agent, wherein the particle size of the white carbon black is 400-600 meshes, and the white carbon black is smashed in a superfine manner. With the adoption of the formula with the components in parts by weight, the tire crown rubber has the advantages of excellent wear resistance, high rubber hardness, high stress at definite elongation and tear strength, good wet slip resistance, and also relatively good wear resistance performance, and both the endurance quality and the high speed performance of the finished product tire reach a relatively high level.

Description

technical field [0001] The invention belongs to the technical field of tire manufacture, and in particular relates to an automobile tire crown rubber. Background technique [0002] Tires are one of the important parts of the car. They are in direct contact with the road surface, and work together with the car suspension to ease the impact of the car while driving, ensuring that the car has good seating comfort and smooth driving; ensuring that the wheels and the road are in good condition The adhesion of the tire improves the traction, braking and passability of the car; bearing the weight of the car, the important role played by the tire on the car has attracted more and more attention. Automobile tires are especially important in the use of automobiles. Automobile tires are related to the safety performance of automobiles. [0003] In 1895, with the appearance of automobiles, pneumatic tires were widely developed. The first samples of automobile tires appeared in France i...
