Problems solved by technology

[0011] Generally, natural rubber and synthetic rubber are used together in the sidewall rubber formula. If it is used together with butadiene rubber, the amount of blending should not be too high, because multiple uses can improve the flex cracking resistance of the sidewall rubber, but the sidewall strength and The tear resistance also decreases, and the adhesive performance of unvulcanized rubber is not good. Therefore, the blending amount of butadiene rubber is preferably 30-50 parts

Abstract

The invention belongs to the field of tire manufacturing technology, and specifically relates to a sidewall rubber of an automobile tire. The sidewall rubber of the automobile tire is characterized in that the sidewall rubber comprising the following components of natural rubber, butadiene rubber, styrene butadiene rubber, ethylene propylene diene monomer rubber, polybutadiene rubber, zinc carbonate, light calcium carbonate, stearic acid, talcum powder, titanium dioxide, low structure high-abrasion furnace black, white clay, zinc oxide, stearic acid, Santo white crystal, high aromatic hydrocarbon oil, an accelerant, paraffin, Santo flacks, insoluble sulfur, carbon black, aluminium hydroxide, alkyl phenol disulfide and magnesium oxide. By adopting the formula composed by the above components, the sidewall rubber of the automobile tire has relatively good strength and elongation property, can endure atmospheric aging, flex cracks and mechanical damages, can protect the tire body from corrosion of the mechanical damages, sunlight, wind and rains.

Description

technical field [0001] The invention belongs to the technical field of tire manufacturing, and in particular relates to a side rubber for automobile tires. 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 Fra...
