All-steel tread formula with high wear resistance and long mileage and preparation process of all-steel tread formula

Abstract

The invention relates to an all-steel tread formula with high wear resistance and long mileage and a preparation process of the all-steel tread formula. The all-steel tread formula comprises the following components: 100 parts of base rubber; 45 to 60 parts of super wear-resistant carbon black; 0.5-5 parts of a carbon black dispersant; 1-3 parts of stearic acid; 2.5 to 3.5 parts of zinc oxide; 1-3parts of a homogenizing agent; 1-3 parts of an anti-aging agent; 0-2 parts of tackifying resin; 0.5 to 2.0 parts of protective wax; 1.0 to 1.6 parts of sulfur; 0.6 to 1.5 parts of a sulfenamide accelerator. According to the invention, the carbon black with low heat generation and high wear resistance is adopted; meanwhile, an NR / BR / SBR (natural rubber / polyisoprene rubber / styrene butadiene rubber)three-gel combined system is adopted; the carbon black dispersant capable of participating in the reaction of rubber and carbon black is used, the interaction between rubber and carbon black is enhanced, the aggregation of the filler and the heat generation of the rubber material are reduced, the adverse effect of hysteresis on aging is reduced, and the friction coefficient of the rubber materialis reduced, so that the wear resistance and durability of a tread can be effectively improved.

Description

technical field [0001] The invention relates to a formula of tire tread rubber and a preparation process thereof, in particular to an all-steel tread formula and a preparation process thereof, and belongs to the technical field of tire production. Background technique [0002] The wear resistance of the tire is the most important factor determining the durability of the tire. About more than 98% of today's car tires are replaced or scrapped because of the use of polishing. Therefore, wear has become the most concerned topic in tire design and production technology. [0003] At present, the wear resistance of tires is far from ideal. During the use of all-steel radial truck tires, due to the need to bear the full load of the vehicle, the driving speed is high, the mileage is long, and it is constantly impacted and rubbed by the road surface. Shear deformation occurs, and its wear is more serious than that of ordinary tires, so the demand for improving its wear performance ...
