Abstract

Tread rubber for preparing a high performance tire comprises the following raw materials by weight: 60-100 parts of natural rubber, 0-30 parts of butadiene rubber, 0-30 parts of solution polymerized stirene-butadiene rubber, 1-3 parts of stearic acid, 3-5 parts of zinc oxide, 1-1.6 parts of an accelerator, 0.3-0.8 part of sulfur, 3 parts of an antioxidant, 40-55 parts of carbon black, 0-15 parts of white carbon black, 0-1.5 parts of a coupling agent, 0.5-2.5 parts of an anti reversion agent and 0.1-0.25 part of antiscorcher CTP. The invention also provides a method for preparing the tread rubber. The tread rubber uses the anti reversion agent to replace part of sulphur content to form a thermodynamically-stable monosulfide bond, disulfide bond, and mixed crosslinked bond with polysulfide bond flexibility. The tread rubber formula has low heat, good abrasion resistance, good aging resistance, high tear strength and anti reversion and other properties, and can improve the service life of the tire.

Description

technical field [0001] The invention relates to the field of chemical industry, in particular to rubber tires, in particular to a tread rubber for preparing high-performance tires. Background technique [0002] With the implementation of the tire labeling law, the requirements for low rolling resistance, high wear resistance and wet grip resistance of tires have become more stringent, and the requirements for improving the wear resistance of green tires and reducing the heat generation of formulas have become an important task for tire developers. topic. [0003] Usually, by optimizing the filler system and vulcanization system, the wear resistance and dynamic performance can improve the tire's wear resistance, aging resistance and reduce heat generation, but considering the comprehensive performance, such as using high wear-resistant carbon black or White carbon black, but the mixing difficulty is high, and it may not achieve good wear resistance and heat generation effect...
