AI Technical Summary

Problems solved by technology

However, the specific surface area of ​​silica is large, and it is not easy to disperse in rubber. The use of silane coupling agent can improve the dispersion of silica, and the full combination of silica and silane coupling agent also needs to change the process and carry out some special processes. To promote the combination of silica and silane coupling agent, improve the dispersion of silica to achieve the predetermined goal

Abstract

The invention discloses all steel truck radial tire tread rubber. The tread rubber is prepared from following raw materials by weight: 100 parts of natural rubber and / or alkadiene synthetic rubber, 10-100 parts of carbon black, 1-10 parts of sulphur, and 1-10 parts of a sulfuration promoter. According to the tread rubber, under the premise of not changing the rubber mixing process conditions at present, by changing the formula and changing raw materials and the using amount thereof of a reinforcing system and a sulfuration system, the rolling resistance is reduced and the rubber material performance is improved, thus facilitating reduction of rolling resistance of a tyre and reducing the fuel consumption.

Description

technical field [0001] The invention belongs to the field of rubber production, in particular to a tire tread rubber. Background technique [0002] This year, oil resources are facing depletion, and international oil prices continue to rise. The fuel consumption performance of automobiles has become an important factor in the purchase of automobiles, and low-fuel consumption vehicles have also become the general trend. During the driving process of the car, many internal factors such as the weight of the car, wear and tear of parts, and external factors such as wind resistance will cause fuel consumption. The rolling resistance generated by the friction between the tire and the ground accounts for 20% of the total fuel consumption. [0003] When the vehicle is running, the loads applied to the tires cause deformation of the tires. Since rubber, the main component of tires, is viscoelastic, this type of material loses some of its energy and converts it into heat when the ti...
