Abstract

The invention relates to rubber, in particular to abrasion-resistant rubber, and belongs to the technical field of rubber. The abrasion-resistant rubber is prepared from the following components in parts by weight: 60 to 80 parts of phenyl siloxane rubber, 20 to 40 parts of polypropylene, 10 to 20 parts of microcrystalline glass particle, 40 to 60 parts of shajiang black soil, 5 to 10 parts of Pr2O3, 5 to 10 parts of an antioxidant, and 5 to 10 parts of a lubricant. The abrasion-resistant rubber has the advantages that by adding the microcrystalline glass particles, the mechanical strength ishigh, the insulation property is excellent, the dielectric loss is little, the dielectric constant is stable, the heat expansion coefficient can be adjusted within the larger range, the chemical corrosion-resistant property, abrasion-resistant property and thermal stability are good, and the use temperature is high.

Description

field of invention [0001] The invention relates to a rubber, in particular to a wear-resistant rubber, and belongs to the technical field of rubber. Background technique [0002] With the development of the economy, the demand for rubber is increasing day by day. Rubber is the latex of plants such as rubber trees and rubber grasses. After processing, it is a material with elasticity, insulation, impermeability, and air impermeability. Rubber is divided into natural rubber and synthetic rubber according to raw materials. Natural rubber mainly comes from Hevea trilobata tree. When the skin of this rubber tree is cut open, milky white juice will flow out, which is called latex. After coagulation, washing, molding, Dry to obtain natural rubber. Rubber products Synthetic rubber is made by artificial synthesis, and different types of rubber can be synthesized by using different raw materials (monomers). From 1900 to 1910, chemist C.D. Harris (Harris) determined that the structu...
