Abstract

The invention discloses rubber for an automobile tire. The rubber is prepared from the following raw materials in parts by weight: 25-35 parts of 1,3-butadiene, 25-35 parts of styrene, 20-26 parts of nickel naphthenate, 15-19 parts of triisobutylaluminum, 8-12 parts of ethylene, 8-12 parts of propylene, 10-16 parts of dicyclopentadiene, 5-9 parts of chlorobutadiene, 3-5 parts of rosin, 3-5 parts of ethylidene norbornene, 20-24 parts of 1,4-hexadiene, 12-16 parts of zinc oxide, 5-8 parts of clay, 7-12 parts of barite, 7-15 parts of carbon black, 5-9 parts of 2, 6-di-t-butyl-4-methylphenol, 3-5 parts of toluene and 1-2 parts of toluene-heptane. The rubber for the automobile tire, which is disclosed by the invention, has the beneficial effects that toughness and wear resistance of the tire are maintained and meanwhile, the heat resistance of the rubber is significantly improved and can reach 2-3 times of that of commercially available similar products after testing so that the driving safety is improved.

Description

technical field [0001] The invention relates to a rubber for automobile tires. Background technique [0002] Tires are circular elastic rubber products that are rolled on the ground and rolled on various vehicles or machinery. Usually installed on metal rims, it can support the body, buffer external impact, realize contact with the road surface and ensure the driving performance of the vehicle. Tires are often used under complex and harsh conditions, and they are subjected to various deformations, loads, forces, and high and low temperature effects during driving, so they must have high load-bearing performance, traction performance, and cushioning performance. At the same time, it is also required to have high wear resistance and flex resistance, as well as low rolling resistance and heat generation. After the car has been running for a long time, the tires are prone to high friction and high temperature, which may cause dangers such as tire blowouts. Contents of the in...
