Abstract

The invention discloses high-wear-resistance rubber for toy balls. The high-wear-resistance rubber comprises, by weight, 25-50 parts of butadiene rubber, 9-20 parts of nitrile rubber, 20-30 parts of light calcium, 9-11 parts of wear-resistant agent, 5-7 parts of zinc carbonate, 14-15 parts of vulcanizing agent, 2-3 parts of dioctyl phthalate, 1.2-1.8 parts of spray carbon black, 2-4 parts of coumarone, 14-15 parts of xylene resin, 10-12 parts of antiager RD, 3-5 parts of asphalt, 5-7 parts of promoter CZ and 2-4 parts of softener. The rubber has excellent heat resistance, wear resistance, aging resistance and elasticity and good mechanical performance.

Description

technical field [0001] The invention relates to rubber, in particular to a high abrasion-resistant rubber used for toy balls. Background technique [0002] Early rubber was latex taken from plants such as rubber trees and rubber grasses, which were processed into materials with elasticity, insulation, impermeability to water and air. High elastic polymer compound. It is divided into butadiene rubber and synthetic rubber. Butadiene rubber is processed by extracting gum from rubber trees, rubber grass and other plants; synthetic rubber is obtained by polymerization of various monomers. However, the synthetic rubbers currently on the market generally have low wear resistance and cannot meet the increasing demands of the market. Toy balls are one of rubber products. With the improvement of people's quality of life, there is a higher demand for the wear resistance of toy balls. Contents of the invention [0003] Based on the technical problems existing in the background tec...
