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
The invention belongs to tread rubber technical field, be specifically related to a kind of meridian tyre.
Background technology
Radial is widely used in engineering transportation equipment now, and in use, because working conditions is relatively harsh, not cut resistant when using such as have sharp-pointed ore pavement conditions under more bad pavement conditions under, easily collapses and use up block; The existing tread rubber that can adapt to more bad pavement conditions, when using under fair speed condition, dynamic heat build up is high, easy delamination, bulge.Existingly can adapt to that more bad pavement conditions can use again under fair speed condition, under the natural condition such as daylight long-term to place easily aging.
Though TBR tire tread formula lays particular emphasis on the compound physical performance need solving certain aspect in prior art.But fail the relation of the every physical and mechanical properties of overall equilbrium tread mix.
Summary of the invention
In order to solve above-mentioned technical problem, the invention provides a kind of meridian tyre.The natural rubber that tread rubber of the present invention adopts, styrene-butadiene rubber(SBR), suitable 1,4-polyisoprene rubber mixes, coordinate other auxiliary materials not only to have good cut resistant, resistance to puncture, the expansion of cracking resistance mouth and anti tear and fall block performance, but also have that dynamic heat build up is lower, the good feature of resistance toheat, and can life-time service, not easily aging, tire wear, the resistance to deterioration of preparation are good.
A kind of meridian tyre of the present invention is realized by following technical scheme:
Described tread rubber comprises the component of following portions by weight:
Natural rubber 70-90 styrene-butadiene rubber(SBR) 10-50
