Abstract

The invention discloses tread rubber with high-cutting and tearing resistant performance and low-dynamic heat generation. Natural rubber, which serves as a main material, and butadiene styrene rubber, intermediate and super wear-resisting carbon black, anti-crack resin, a multifunctional vulcanizing active agent and an anti-vulcanizing reversion agent, which serve as main auxiliary materials, areblended in an internal mixer to manufacture blended rubber, and the blended rubber is formed into a tread semi-finished product in a mode of extrusion by an extruder. The rubber has the advantages ofhigh tensile strength, high tearing strength, high stretching stress, high cutting resistant performance, low dynamic heat generation, high stability, high wear-resisting property and high anti-flexure crack performance. By using tires with the tread rubber, dumpers can be used on sharp ore road surfaces at a high speed, and the service life of the tires is long.

Description

technical field [0001] The invention relates to a tire rubber compound, in particular to a tread rubber compound with good cutting and tear resistance and low dynamic heat generation. Background technique [0002] Dump trucks used in mines, etc., have a large carrying capacity and fast driving speed, and need to drive on roads covered with sharp ore. Existing tread rubbers that can adapt to road conditions are not resistant to cutting when used on sharp ore road conditions, and are easy to collapse and fall off; existing tread rubbers that can adapt to sharp ore road conditions cannot When used under conditions, the dynamic heat generation is high, and it is easy to delaminate and bulge. Contents of the invention [0003] The purpose of the present invention is to provide a tire tread rubber that is especially suitable for mine dump trucks to be used under sharp ore road conditions and higher speed conditions. The tread rubber not only has good cutting resistance, punctu...
