Problems solved by technology

[0008] Since cis-1,4-polyisoprene rubber has high tear strength and adhesive properties, pure cis-1,4-polyisoprene rubber is generally used in the tread compound formula of all-steel radial tires raw rubber system, but the raw rubber system of pure cis-1,4-polyisoprene rubber has general wear resistance
[0009] At the same time, the current formula adopts the filling system of N234 carbon black 30phr + white carbon black 20phr + silane coupling agent, which can reduce the heat generation of the rubber compound, so the current low rolling resistance formula adopts this filling system, but it is different from the common all-steel radial tire tread formula Insufficient wear resistance in comparison
[0010] In short, there are two reasons for the lack of wear resistance of the tread formula.

Description

technical field [0001] The invention belongs to the field of chemical industry, and in particular relates to an all-steel tread compound formula with both wear resistance and low heat generation and a preparation method thereof. technical background [0002] For the design of the all-steel tread rubber formula, it is required to have high constant elongation, high strength, high elasticity, low heat generation, and medium hardness to meet the performance of all-steel tires with wear resistance, low rolling resistance, and puncture resistance. [0003] Of course, tires have different service conditions and different uses. Generally, they are divided into guide wheel and driving wheel tires, and the hardness and constant elongation stress should be adjusted appropriately. The road surface (general off-road pattern) is relatively lower, but due to the high rigidity of the crown of the radial truck tire, the hardness must be kept high, and at the same time, the elasticity must b...
