Abstract

The invention belongs to the technical field of rubber tire preparation, and in particular relates to a multi-component tire tread rubber and a preparation method thereof. The multi-component tire tread compound is prepared from the following components in parts by weight: 60-80 parts of high-trans 1,4-polyisoprene rubber; 50-60 parts of amino-terminated styrene-butadiene rubber 40-50 parts of hydroxyl-terminated polybutadiene rubber; 30-50 parts of white carbon black; 5-10 parts of isocyanate; 2-8 parts of other additives. Hydroxyl-terminated polybutadiene rubber, compared with the butadiene rubber in the traditional formula, has been modified with terminal groups, and can form a polyurethane cross-linked structure with isocyanate to enhance the wear resistance of the rubber compound; wet mixing is adopted, and silica is dispersed Good effect, can improve wear resistance.

Description

Technical field [0001] The present invention is a rubber tire preparation technology field, and especially involves a multi -sets of tire tire glue and its preparation methods. Background technique [0002] With the development of the modern automotive industry, the requirements for tire performance are getting higher and higher: on the basis of ensuring certain anti -moisture and slippery properties, it will improve wear resistance, heat -resistant oxygen, reduce rolling resistance, and reduce heat.The focus. [0003] The tire glue is a layer of rubber that is in contact with the exterior layer of the tire and the surface of the surface and the surface is printed on the surface, which can make the tires have high abrasion resistance and antioxidant, reduce rolling resistance to provide orientation.Prevent the cutting and piercing of the curtain line layer.Most of the existing technologies are made of raw rubber such as natural rubber, butadylene rubber, cashmere isoprene rubber,...
