Rubber compound of high-tensile-modulus high-wear-resistance tread rubber, and preparation method of rubber compound

Abstract

The invention discloses a rubber compound of high-tensile-modulus high-wear-resistance tread rubber, and a preparation method of the rubber compound. The rubber compound comprises 100 parts of natural rubber, 55 parts of carbon black, 6 parts of an environmentally-friendly peptizer, 2 parts of stearic acid, 5 parts of zinc oxide, 2 parts of an anti-ageing agent 4010NA, 1.5 parts of protective wax, 1.5 parts of tackifying resin, 3 parts of aramid short fiber, 2 parts of an adhesive, 5 parts of sulfur, 1.8 parts of an accelerant NS, 1 part of shredded ginger fiber and 2 parts of potato fiber. After the potato fiber is added, the three-dimensional fiber net-like structure locks up the shredded ginger fiber, so that the performance of the rubber product is integrally enhanced, the shredded ginger fiber is wrapped with the potato fiber, and the potato fiber active free radical can promote adhesion with a rubber matrix; the waste is utilized, so that environmental protection is benefited.

Description

technical field [0001] The invention relates to the technical field of rubber, in particular to a rubber compound of high constant elongation and high wear-resistant tread rubber and a preparation method thereof. technical background [0002] As people have more and more requirements for cars, tires have become a very important research object in addition to the interior functions and safety of cars. Tires support the entire weight of the car and bear the load, transmit traction and braking force, and ensure the adhesion between the wheel and the road surface; they can also absorb and slow down the impact and vibration generated by the car during driving, which can not only slow down the vibration of car parts Destroying and improving ride comfort, it can also reduce the noise generated by the car at high speeds, ensuring the safety, stability and comfort of the car. The outermost layer of the tire is called the tread. Through a specific pattern, the tire has traction and b...

Problems solved by technology

[0004] The invention mainly solves the technical problems that the single SBR formula in the prior art is prone to cracks, punctures, the more ordinary fibers there are, the greater its air permeability, and the poorer degree of adhesion with rubber, and it provides a high specific elongation and high wear resistance. The rubber compound of tread rubber and its preparation method, the rubber compound can achieve the effect of high constant elongation and high wear resistance through the synergistic effect between the components
