Problems solved by technology

Among them, ordinary rubber is heavy, easy to spit frost, not easy to corrode, and not environmentally friendly; TPR material has poor anti-slip performance, heavy weight, and easy to turn yellow; while PU material is strong in water absorption, easy to yellow, easy to break, and low elongation. Poor, not resistant to water, easy to rot
[0003] Microcellular foamed rubber is a rubber with pores formed after foaming rubber. Therefore, it has lighter performance than non-foamed rubber, but its wear resistance is reduced, so it can only be used for soles with lower wear resistance requirements. It cannot be used for the production of soles that require high wear resistance
In the prior art, adding inorganic fillers to the sole material will increase the density of the sole compound, but the weight of the sole will increase, and the wear and tear properties will also decrease

Abstract

The invention relates to a foamed shoe sole material and a preparation method thereof. The shoe sole material comprises, by weight, 100 parts of rubber body, 35-45 parts of filler, 25-35 parts of operating oil, 1-4 parts of accelerant, 0.5-1 part of stearic acid, 3-7 parts of zinc oxide, 25-50 parts of white carbon black, 20-30 parts of modified kaolin, 2-5 parts of silane coupling agent, 1-5 parts of inorganic nano crystal whisker, 0.5-3 parts of 4,4-oxybis(benzenesulfonyl hydrazide), 0.3-1.5 parts of paraffin, 5-8 parts of polyethylene glycol, 1-3 parts of styrenated phenol, 1-3 parts of phenolic resin and 1.5-4 parts of sulfur. The foamed shoe sole material has more uniform foaming holes, the weight of a shoe sole is reduced, and meanwhile, the shoe sole material has relatively high wear resistance. The foamed shoe sole material is high in abrasion and light, and can be conveniently used for preparing mountaineering shoe soles and tennis shoe soles.

Description

technical field [0001] The invention relates to a foamed shoe sole, in particular to a foamed shoe sole material and a preparation method thereof. Background technique [0002] The soles currently on the market are mainly made of ordinary rubber, TPR material (Thermo-Plastic-Rubber material, thermoplastic rubber material), or PU material (polyurethane, polyurethane). Among them, ordinary rubber is heavy, easy to spit frost, not easy to corrode, and not environmentally friendly; TPR material has poor anti-slip performance, heavy weight, and easy to turn yellow; while PU material is strong in water absorption, easy to yellow, easy to break, and low elongation. Poor, not resistant to water, easy to rot. [0003] Microcellular foamed rubber is a rubber with pores formed after foaming rubber. Therefore, it has lighter performance than non-foamed rubber, but its wear resistance is reduced, so it can only be used for soles with lower wear resistance requirements. It cannot be use...
