Automobile tire

Abstract

The invention relates to an automobile tire, and provides a tire with little rolling friction, high strength and good wear resistance. The diameter of the automobile tire is less than 90 cm; the automobile tire is added with the following components: 2-5% of asphalt fiber, 2-5% of viscose fiber and 5-10% of modified natural rubber, wherein the asphalt fiber is acrylonitrile fiber or polyester fiber; the diameter of the acrylonitrile fiber is not less than 15 microns; the tensile strength of the polyester fiber is not less than 700 MPa; the strength of the viscose fiber is greater than 48 cN / dtex. The diameter of the acrylonitrile fiber is 15-16 microns. The content of phosphorus in raw materials of the tire is less than 200 ppm. The content of insoluble matters in the raw materials of the tire is lower than 20%.

Description

technical field [0001] The present invention relates to an automobile tire. Background technique [0002] In the prior art, people have been trying to reduce the rolling resistance and heat generation of tires and reduce the fuel consumption of automobiles. Over the years, there have been more and more technologies to reduce the fuel cost of automobiles from tires. For example, the improvement of the track of tire components and the improvement of tire side surfaces makes the technology to reduce the fuel cost of automobiles especially numerous. Moreover, in recent years, technologies for low fuel consumption have been applied not only to passenger car tires, but also to heavy vehicles such as trucks and buses. [0003] As a method for reducing the exothermicity of rubber materials, known methods include using fillers with weak reinforcing properties or reducing the amount of reinforcing fillers, etc. However, this method of reducing fuel consumption based on changing fille...

Problems solved by technology

[0003] As a method to reduce the heat generation of rubber materials, known methods include using fillers with weak reinforcing properties or reducing the amount of reinforcing fillers, etc. However, this way of reducing fuel consumption based on changing fillers will be to a certain extent Decrease the strength and hardness of the rubber material, and there is a dilemma

[0004] At the same time, when natural rubber is used for high-load tires, it is inevitable to transform it. In this case, the production efficiency is very low, and the molecular chain must be cut off during the transformation. Natural rubber itself has high polymerization properties, such as rubber strength and Low coefficient of rolling friction, etc. will instead be lost

In the prior art, natural latex and enzymes are sometimes mixed, and heated and fermented with the cooperation of surfactants, but the solution to the above problems is still not obvious enough
