Abstract
The present invention relates to rubber for tire technical field, specifically a kind of ageing-resistant Tire tread rubber composition, it is characterised in that, on the basis of the rubber components of 100 parts by weight, also include, the carbon black between 40~70 parts by weight, the rubber processing softening agent between 2~10 parts by weight, 0.1~0.5 parts by weight peptizer, the zinc oxide of 2~10 parts by weight, the antioxidant of 1~5 parts by weight, the anti-agent of reverting of 1~5 parts by weight, 0.5~3 parts by weight sulphur, 0.5~3 parts by weight vulcanization accelerator;Rubber components include the natural gum of 70~100 parts by weight and the butadiene rubber of 0~30 parts by weight.The present invention is added new anti-agent of reverting, is obviously improved the ageing-resistant performance of formulated rubber material, improved the performance such as tire used later stage abrasion performance, tear-resistant, extend Life of Tyre by new vulcanizing system formula.
Description
Technical field
The present invention relates to rubber for tire technical field, specifically a kind of ageing-resistant tire tread rubber combination of high-performance
Thing.
Background technology
It is well known that with highway and the fast development of logistics, requirement of the people to tire quality is also increasingly
It is high.Expectation to radial heavy duty tire includes abrasion performance, ageing-resistant, service life length, however, during tire used, with
Tire rubs with road surface, inevitably because the fatigue of sizing material, aging cause tire wear.Improve sizing material aging
Can, reduce the important process target that tire wear is always formula worker.
The content of the invention
The purpose of the present invention is exactly to overcome the deficiencies of the prior art and provide a kind of ageing-resistant tire tread rubber combination
Thing, can improve the resistance to ag(e)ing of sizing material, the properties such as abrasion performance, tear-resistant after raising sizing material aging, so as to extend wheel
The service life of tire.
The present invention solves the technical solution that above-mentioned technical problem uses：A kind of ageing-resistant Tire tread rubber composition,
It is characterized in that, on the basis of the rubber components of 100 parts by weight, also include,
Carbon black between 40~70 parts by weight,
Rubber processing softening agent between 2~10 parts by weight,
0.1~0.5 parts by weight peptizer,
The zinc oxide of 2~10 parts by weight,
The antioxidant of 1~5 parts by weight,
The anti-agent of reverting of 1~5 parts by weight,
0.5~3 parts by weight sulphur,
0.5~3 parts by weight vulcanization accelerator;；
Rubber components include the natural gum of 70~100 parts by weight and the butadiene rubber of 0~30 parts by weight.
The preferred carbon black N134 of carbon black.
The invention has the advantages that by new vulcanizing system formula, new anti-agent of reverting is added, makes formulated rubber material
Ageing-resistant performance is obviously improved, and is improved the performance such as tire used later stage abrasion performance, tear-resistant, is extended Life of Tyre.
Embodiment
With reference to embodiment, the present invention will be further described：
Rubber processing softening agent of the present invention, does not refer to oils rubber processing aids singly, further includes stearic acid, protection wax, rubber
The Multifunctional rubber work softening agent such as glue dispersant；
Anti- agent of reverting of the present invention is the auspicious WY518 of Shanghai Qi, can be inserted among polysulfide bond, be formed both in sulfidation
There is the cross-bond that mixes that S has C again, this cross-bond had not only had the stability of monosulfidic bond and cystine linkage, but also had similar polysulfide bond
Pliability.
Sulphur of the present invention can be that the sulphur after having been used for the sulphur powder of tire industry or processing is female
Grain S-80, sulfur consumption is 0.5~3 parts by weight.Contain disulfide bond due to resisting used in the present invention in agent molecule structure of reverting,
Part sulphur atom can be provided in sulfidation and participate in vulcanization, it is therefore proposed that sulfur consumption is suitably reduced, preferably 0.5~2 weight
Part；
Vulcanization accelerator preferred accelerators NS of the present invention, curingprocess rate is fast, deferred good.
The physical mechanical property of embodiment and comparative example（Conditions of vulcanization is 150 DEG C, 30min）
From the point of view of formulation Example and original contrast, by new vulcanizing system formula, new anti-agent of reverting is added, sizing material is old
Physical property, abrasion, tearing force conservation rate after change increase, and ageing-resistant performance significantly increases.
