Abstract

The invention provides a butadiene styrene rubber composition with a wear-resisting characteristic and a preparation method thereof. The butadiene styrene rubber composition comprises the following components in parts by weight: 100 parts of butadiene styrene rubber, 1-30 parts of modified butylbenzene powdered rubber and can also comprise 1-30 parts of hydroxyl-terminated liquid butadiene styrene rubber and the like. In the butadiene styrene rubber, the content of the bound styrene is 15-50%, and the Mooney viscosity is 30-90; the modified butylbenzene powdered rubber is obtained by modifying the surface of the butylbenzene powdered rubber prepared by a radiation crosslinking method by using ethanthiol and potassium persulfate under the existence of polyethylene glycol, wherein the content of the bound styrene is 15-60% and the average particle size is 50-300nm; and the content of gel is 70-98%. The butylbenzene vulcanized rubber can well achieve the balance among the rolling resistance, the slippery resistance and the wear resistance, and is suitably used for tread rubber.

Description

technical field [0001] The invention relates to the field of rubber, in particular to a styrene-butadiene rubber composition and a preparation method thereof. Background technique [0002] With the increasingly stringent policies and regulations for carbon dioxide emission reduction and the increasing shortage of oil resources, how to reduce fuel consumption has become the focus of attention of the automobile industry and users. Reducing the rolling resistance of tires is one of the important measures to reduce automobile fuel consumption. [0003] In the study of reducing the rolling resistance of tire rubber (mainly tread rubber), the so-called "magic triangle" problem of contradictory rolling resistance, wet skid performance and wear resistance has been encountered. Simply increasing the amount of softener can improve the tire's wet skid resistance, but its wear resistance will decrease and rolling resistance will increase. Increasing the amount of reinforcing filler (ca...
