Abstract

The invention discloses a preparation method of a temperature-resistant wear-resistant EVA (ethylene-vinyl acetate) sole. The preparation method includes the steps: (1) raw material weighing; (2) enclosed mixing treatment; (3) open mixing treatment; (4) granulation foaming treatment. In the preparation process of the EVA sole, raw material components are reasonably selected and blended, the treatment process is optimized and improved, and finally prepared finished products have good temperature resistance, wear resistance and comprehensive characteristics and high popularizing use values.

Description

technical field [0001] The invention relates to the technical field of processing shoe sole materials, in particular to a preparation method of a temperature-resistant and wear-resistant EVA material shoe sole. Background technique [0002] Ethylene-vinyl acetate copolymer (EVA) has good plasticity, elasticity and processability, and the foamed material has the advantages of low density, good mechanical properties, and easy coloring. It is widely used in shoe sole materials, but EVA materials It has the disadvantage that its wear resistance is not as good as that of rubber shoe materials, thus limiting its partial application. At present, the improvement of EVA materials is mostly limited to the combination of raw material components, and there are few in-depth studies on the preparation process. Contents of the invention [0003] The object of the present invention is to provide a kind of preparation method of temperature-resistant and wear-resistant EVA material sole ai...
