High temperature resistance sole material for safety shoes

Abstract

The invention relates to a high temperature resistance sole material for safety shoes. The sole material is prepared by, by weight, blending the following materials: 32-36 parts of natural rubber, 20-25 parts of synthetic rubber, 6-10 parts of a vulcanizing agent, 5-8 parts of softwood particles, 12-22 parts of butyronitrile, 15-18 parts of sulfur, 7-16 parts of modified glass fibers, 5-10 parts of zinc oxide, 17-24 parts of white carbon black, 6-12 parts of magnesium oxide, 15-18 parts of stearic acid, 3-4 parts of an accelerant, and 1-2 parts of an additive. The material is reasonable in proportion of the components; and sole products manufactured by adopting the component formula have better capabilities of high temperature resistance, insulation and wear resistance, and can meet high usage requirements of high temperature resistance.

Description

technical field [0001] The invention belongs to the field of preparation of shoe sole materials, and in particular relates to a shoe sole material for high-temperature-resistant labor insurance shoes. Background technique [0002] The rubber soles of labor insurance shoes used in high-temperature environments have low high-temperature resistance. Usually, when they come into contact with a hot surface of 30°C, the temperature of the inner sole surface can reach as high as 40°C within 20 minutes, and the material will soften, Melting, cracking and other phenomena are difficult to meet the high safety protection requirements. [0003] The invention relates to a sole material for high-temperature-resistant labor insurance shoes, which is characterized in that it is formed by mixing the following parts by weight: 32-36 parts of natural rubber, 20-25 parts of synthetic rubber, 6-10 parts of vulcanizing agent, and 5-5 parts of cork particles. 8 parts, 12-22 parts of nitrile, 15-1...
