Tire rubber having cutting and abrasion resistance and low thermogenesis

Abstract

The invention relates to a development method of tire rubber having cutting resistance and abrasion resistance as well as low thermogenesis and solves the problem of early damage of tires traveling to and fro between paved roads and non-paved roads of mining areas in mid-short distance heavy-load regions, that is, requirements of the tires for puncturing resistance and cutting chipping resistance during traveling on the non-paved roads of the mining areas are met, requirements of the tires for abrasion resistance and low thermogenesis during traveling on the paved roads at high speeds are also met, so that the early damage of the tires is reduced, and the service lives of the tires are prolonged. According to the tire rubber, the rubber takes natural rubber as a main body and is synthesized with a small number of butadiene-styrene copolymers, and the basic abrasion resistance and cutting resistance of the tire rubber are guaranteed; a reinforcing system adopts both carbon black and white carbon black, in combination of a semi-efficient vulcanization system and a matched vulcanization technology, the excellent cutting resistance and abrasion resistance are acquired, and meanwhile, the thermogenesis of the rubber is also reduced.

Description

Technical field: [0001] The invention relates to the development of a tread rubber with both cutting resistance and wear resistance and low heat generation, which can be used not only for tires running on non-paved bad roads such as mountainous areas, but also for high-speed tires on paved roads. Running tires. Background technique: [0002] With the rapid development of the country's economy and the improvement of road conditions for transportation, vehicle tires originally used in mountainous areas, mining areas, engineering construction and short-distance transportation, in addition to the original harsh conditions such as resistance to cutting, puncturing, and many turns, are also To meet the high speed, wear resistance and low heat generation requirements of certain medium and long-distance products, this puts forward more comprehensive and comprehensive performance requirements for tires. [0003] According to existing literature reports, in the past, the research on ...
