Abstract

The invention discloses a method for preparing a high wear-resistant rubber material for tires. The prepared high wear-resistant rubber material for tires has high tensile strength and low wear value, and its mechanical properties and wear resistance are relatively high. Good, at the same time its corrosion resistance has also been greatly improved. Sulfur, potassium hexatitanate whiskers and boron nitride act synergistically. On the one hand, potassium hexatitanate whiskers and boron nitride can be used as sulfur carriers to promote the dispersion of sulfur in the rubber base and prevent the agglomeration of sulfur. Promote its uniform distribution in the substrate and improve the mechanical properties of rubber. At the same time, it can be used as a link between potassium hexatitanate whiskers and boron nitride, so that potassium hexatitanate whiskers and boron nitride can be effectively combined and dispersed in the rubber substrate. In the middle, a three-dimensional network is formed to enhance the wear resistance and tensile properties of rubber; the filler is modified by using modified PTFE emulsion, which enhances the interfacial bonding force between the filler and the rubber substrate, and improves the tensile strength of the rubber .

Description

technical field [0001] The invention belongs to the technical field of rubber, in particular to a method for preparing a high wear-resistant rubber material for tires. Background technique [0002] Rubber is extracted from plants or artificially synthesized, and then processed into elastic, insulating, impervious to water and air polymer materials. Rubber materials are widely used in industries such as tires and in all aspects of life. However, rubber materials are often difficult to obtain high mechanical strength without reinforcement. Existing electric vehicle tires generally have disadvantages such as poor wear resistance and poor corrosion resistance, which affect the service life and safety of use. How to improve tire tread wear resistance and corrosion resistance is an important topic in the tire industry. Contents of the invention [0003] In view of the above problems, the present invention aims to provide a tire rubber material with good wear resistance and cor...
