Embodiment 1

[0033] A radial tire tread compound consists of the following components by weight ratio:

[0034] Natural Rubber 50 Styrene Butadiene Rubber 40

[0035] cis 1,4-polyisoprene rubber 10 silane coupling agent Si-692

[0036] Stearic acid 2 sulfur 2.5

[0037] Carbon black 45 Silica 10

[0038] Plasticizer A2 Resole phenolic resin 2

[0039] Zinc Oxide 4 Antiaging Agent 3

[0040] Anti-reversion agent WK-9012 Accelerator DM1.2

[0041] Accelerator CZ1 aromatic oil 12.

[0042] The natural rubber is 1# smoked sheet rubber or 3# smoked sheet rubber.

[0043] Described carbon black is that N220 and N234 are mixed according to the ratio of 1:1 by weight,

Abstract

The invention relates to tread rubber of a radial tire. The tread rubber disclosed by the invention is prepared by mixing natural rubber, butadiene styrene rubber and cis-1,4-polyisoprene rubber; due to the matching of other auxiliary materials, the tread rubber not only has good properties of cutting resistance, prickling resistance, crack extension resistance and tear and chipping resistance, but also has the characteristics of lower dynamic heat generation and better heat resistance; the tread rubber can be used for a long time and is not easy to age, and a prepared tire is good in abrasion resistance and aging resistance.

Description

technical field [0001] The invention belongs to the technical field of tread rubber, in particular to a radial tire tread rubber. Background technique [0002] Radial tires are now widely used in engineering transportation equipment. During use, due to the relatively harsh conditions of use, they are not resistant to cutting when used on poor road conditions such as sharp ore road conditions, and are easy to collapse and fall off; Tread rubber that can adapt to poor road conditions has high dynamic heat generation and is easy to delaminate and bulge when used at high speeds. The existing ones that can adapt to poor road conditions and can be used at higher speeds are prone to aging when left for a long time under natural conditions such as sunlight. [0003] Although the all-steel radial truck tire tread rubber formula in the prior art focuses on solving the physical performance needs of the rubber material in a certain aspect. But fail to comprehensively balance the relat...
