Abstract

The invention relates to an automobile tire, the tread material of which is a rubber composition comprising the following components in parts by weight: 65-75 parts of styrene-butadiene rubber and 25-35 parts of natural rubber as matrix rubber; 30 to 60 parts of modified fumed silica and 30 to 60 parts of carbon black as a functional filler; 10-20 parts of specific boron hybrid methyl vinyl MQ silicon resin and 5-10 parts of synthetic terpene resin as tackifying resin; 5-10 parts of a vulcanizing agent and 2-5 parts of a vulcanization accelerator. The cured automobile tire has the advantages of high elasticity, self-flame retardancy, favorable wear resistance, excellent road holding performance and excellent road holding durability, and has wide application prospects in the field of medium / large-sized automobile tires.

Description

technical field [0001] This invention is a divisional application of the Chinese patent "Rubber Composition for Treads of Medium and Large Automobile Tires". The application date is October 31, 2017, and the application number is 201711049174.7. The invention relates to an automobile tire and belongs to the technical field of automobiles. [0002] technical background [0003] Tires are one of the most important components of a car. Its main function is to support the entire weight of the vehicle, bear the load of the car, transmit traction and braking torque, and ensure the adhesion between the wheel and the road. Most of the tires are rubber material. But in recent years, with the development of the economy, the number of cars has increased, and the requirements for rubber have become higher and higher. Not only does it require its wear resistance, but now in order to pursue the comfort of the car, how to reduce and absorb the rubber of the car? Vibration and impact force...
