Novel high temperature resistant safety shoe sole material

Abstract

The invention relates to a novel high temperature resistant safety shoe sole material, which is prepared by mixing following raw materials in parts by weight: 25 to 30 parts of styrene butadiene rubber, 30 to 35 parts of natural rubber, 3 to 5 parts of dihydroxyl polyester polyol, 10 to 15 parts of butyronitrile, 12 to 18 parts of sulfur, 8 to 16 parts of modified glass fiber, 14 to 22 parts of zinc oxide, 7 to 15 parts of white carbon black, 5 to 12 parts of magnesium oxide, 15 to 18 parts of calcium carbonate, 3 to 4 parts of halogen free fire retardant, and 1 to 2 parts of additive. The formula is reasonable, and the prepared shoe sole has a good high temperature resistant performance, a good insulation property, and a good wear resistant performance, and can meet the high requirementson high temperature resistance.

Description

technical field [0001] The invention belongs to the field of shoe sole material preparation, and in particular relates to a novel high temperature resistant labor insurance shoe sole material. 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 new type of sole material for high-temperature resistant labor protection shoes, which is characterized in that it is made by mixing the following parts by weight: 25-30 parts of styrene-butadiene rubber, 30-35 parts of natural rubber, and 3-5 parts of dihydroxy polyester polyol 10-15 parts of nitrile, 12-18 parts of sulfur, 8...
