Abstract
The invention relates to the technical field of the production of tire rubber, and particularly relates to bias tire tread rubber. The bias tire tread rubber is characterized by comprising the following raw materials inn parts by weight: 20 to 40 parts of butadiene rubber, 10 to 20 parts of natural rubber, 20 to 30 parts of carbon black, 7 to 9 parts of an enhanced active agent, 1 to 2 parts of an anti-aging agent and 1 to 3 parts of sulfur. By adopting the bias tire tread rubber, the abrasion resistance and the aging resistance of the rubber material can be improved, and the hardness is moderate.
Description
Technical field
The present invention relates to tire sealant production technical field, be specifically related to a kind of diagonal tyre surface rubber.
Background technology
Along with the increase of China Higher mileage in highway open to traffic, more and more higher requirement is proposed to the performance of running at high speed of doughnut, meanwhile, along with the enhancing of environmental consciousness, new demand be it is also proposed to the rolling resistance relevant to tire fuel saving.The position at tread rubber place and shared volume determine it to tire drag account for whole tire produce 50% of rolling resistance, even more more, therefore how to improve tread glue formula to reduce the key of tire drag.In addition, the existence of low-grade highway requires again the wear resisting property that tire has had.The use properties of tire to automobile of high-quality seems more and more important, and bias tyre carcass is thick, and during rolling, circumferential deformation is large, and heat-dissipating is high, and heat radiation is slow, and therefore improving the use properties of bias tyre, is also the difficult point that tire formulation design engineering personnel capture.
Summary of the invention
The present invention, in order to overcome the shortcoming of prior art, provides a kind of diagonal tyre surface rubber.
Technical scheme of the present invention is: a kind of diagonal tyre surface rubber, is made up of the raw material of following parts by weight: cis-1,4-polybutadiene rubber 20-40 part, natural rubber 10-20 part, carbon black 20-30 part, enhanced activity agent 7-9 part, anti-aging agent 1-2 part, sulphur 1-3 part.
Enhanced activity agent of the present invention is the novel starting material possessing multiple function be polymerized by silicon-dioxide, coupling agent, Resorcinol.It not only can substitute oxidation station, and can also the dispersion agent of fictitious hosts costliness and leveler, can improve the performance such as wear-resisting, ageing-resistant of sizing material.
Cis-1,4-polybutadiene rubber: cis-1，4-polybutadiene rubber by name entirely, its molecular formula (C

n, belong to mixture.Advantages such as there is good springiness, wear resisting property is strong, resistance to low temperature good, heat-dissipating is low, hysteresis loss is little, flexible resistance, resistance to cracking and dynamic property are good.
Natural rubber: our said natural rubber usually, refers to the natural rubber latex gathered from Para rubber tree, the elasticity decorating film made through the manufacturing procedure such as supersolidification, drying.The natural high moleculer eompound of natural rubber to be a kind of with polyisoprene be main component, molecular formula is (C

Beneficial effect: a kind of diagonal tyre surface rubber of the present invention can improve the performance such as wear-resisting, ageing-resistant of sizing material, and hardness is moderate.
