Abstract

The invention discloses rubber for an auto tire. The rubber is mainly prepared from the following raw materials: natural rubber, carbon black, brominated butyl rubber, sulfur, styrene-butadiene rubber, graphite, a viscose fiber, dicumyl peroxide, metakaolin, benzoic acid, a bamboo fiber, hydroxyl silicone oil, stearyl alcohol, montmorillonite, cis-butadiene rubber, paraffin oil, talcum powder, anage resistor, an accelerant and maleic anhydride. According to the rubber for the auto tire, which is provided by the invention, through a reasonable raw-material formula, the prepared rubber for theauto tire has the advantages of being excellent in the abrasive resistance and the tear resistance of a tire tread, prolonging the service life of the tire, and the like. Furthermore, a preparation method is simple; and the requirement on a device is low.

Description

technical field [0001] The invention relates to the field of tires, in particular to rubber for automobile tires. Background technique [0002] Car 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. Ensure that the car has good ride comfort and ride comfort; ensure that the wheels and the road have good adhesion. Improve the traction, braking and passability of the car. Bearing the weight of the car, the important role played by tires on the car has been paid more and more attention by people. [0003] As an important part of a car, tires play a role in supporting the weight of the vehicle, transmitting traction and braking torque, ensuring the adhesion between the wheel and the road, reducing and absorbing the vibration and impact of the car while driving, and preventing the parts of the car from being severely damaged. Vibration and early...
