Problems solved by technology

[0004] The present invention aims to solve the problem that the current pure natural rubber formula has a large hysteresis, the deformation lags behind the stress, the rolling resistance is relatively large, the relative fuel consumption is large, the dispersion of aramid short fibers is uneven, the more ordinary fibers are, the air permeability is greater, and the rubber is sticky. In order to solve the technical problem of poor compatibility, a rubber compound with low rolling resistance and high wear resistance tread rubber and its preparation method are provided. The rubber compound can achieve low rolling resistance and high wear resistance through the synergistic effect between the components. Effect

Abstract

The invention discloses a tread rubber compound with low rolling resistance and high wear resistance and a preparation method thereof. The compound comprises the following raw materials: 20 parts of natural rubber, 25 parts of butadiene rubber, 75 parts of styrene-butadiene rubber, 70 parts of carbon black, 8 parts of an environmentally-friendly peptizing agent, 0.5 part of stearic acid, 2.5 parts of zinc oxide, 2 parts of an antioxidant 4010NA, 1.5 parts of protective wax, 1 part of tackifying resin, 2 parts of aramid staple fibers, 2 parts of a binder, 1.5 parts of sulfur, 1.4 parts of an accelerant CZ, 1 part of ginger fibers and 2 parts of potato fibers. After the potato fibers are added, a three-dimensional fibrous network structure of the potato fibers binds the ginger fibers firmly, so that the performance of rubber products is overall enhanced, the ginger fibers are wrapped with the potato fibers, so that active free radicals of the potato fibers can promote the binding with a rubber base body; the use of waste facilitates the environmental protection.

Description

Technical field [0001] The invention relates to the technical field of rubber, in particular to a rubber compound of low rolling resistance and high wear-resistant tread rubber and a preparation method thereof. technical background [0002] At present, the number of motor vehicles in my country has exceeded 200 million, and it is still on the rise, which has also brought tremendous pressure to the environment. Energy saving and emission reduction are the general trend of global automobile development. my country's relevant regulations stipulate that domestic passenger car companies must control the average fuel consumption at 5.0L / 100 kilometers, so relevant units also focus on the vehicle's own weight and tires to reduce fuel consumption. And for every 100 kilograms of car weight reduction, the fuel consumption per 100 kilometers can be reduced by 0.7 liters, and the car’s own weight can be reduced by 10%, and the car’s fuel efficiency can be increased by 5.5%. The main functi...
