Abstract

The invention relates to a wear-resistant safety shoe sole material and belongs to the field of preparation of shoe sole materials. The shoe sole material is prepared by mixing the following materialsin parts by weight: 30-35 parts of natural rubber, 15-20 parts of synthetic rubber, 28-32 parts of toluene-2,4-diisocyanate, 12-16 parts of modified glass fiber, 8-10 parts of gamma phase nanometer aluminum oxide, 7-14 parts of white carbon black, 8-16 parts of nanometer silicon dioxide, 3-6 parts of adhesive, 3-4 parts of surface modifier and 1-2 parts of additive. The material provided by the invention is reasonable in proportion and has the characteristics of high toughness, high wear resistance, shock resistance, impact resistance, corrosion resistance and the like. By adopting the material, compared with the special wear-resistant rubber, the production cost is greatly lowered, the wear resistance is improved, and the relatively high wear resistance use requirement can be met.

Description

technical field [0001] The invention relates to the field of preparation of sole materials, in particular to a sole material for wear-resistant labor insurance shoes. Background technique [0002] At present, polyurethane rubber is characterized by its lightness, comfort, cold resistance, and fast processing and molding—multiple physical and mechanical performance indicators can be changed within a certain range through the selection of raw materials and the adjustment of formula, so as to meet the different requirements of users for product performance. , low production cost and many other advantages, it is widely used in the production of shoe soles. However, for soft polyurethane soles, there are poor wear resistance and no hydrolysis resistance, which can easily lead to cracks and fractures on the soles, which limits the application range of polyurethane soles. [0003] The invention relates to a sole material of wear-resistant labor insurance shoes, which is characteri...
