Environment-friendly sole and manufacturing method thereof

Abstract

The invention relates to an environment-friendly sole and a manufacturing method thereof. The manufacturing method comprises the following steps of 1, mixing: mixing, by mass percent, 45%-55% of cornstarch, 25%-35% of EVA or rubber or TPU and 15%-25% of auxiliaries to obtain a mixed material; (2) granulation: putting the mixed material into a granulator for granulation to obtain mixed material particles; (3) injection molding foaming: injecting the mixed material particles into a foaming machine for foaming to obtain a sole primary blank; (4) compression molding: placing the sole primary blank in a mold for compression molding to obtain the environmentally friendly sole. The main material of the environment-friendly shoe sole is corn starch; the corn starch is a renewable environment-friendly material; the materials are easy to obtain; an extraction processing procedure is free of pollution, toxicity and heavy metal residues; when the environment-friendly shoe sole is used as a shoe material, degradation is facilitated, rubber pollution is reduced; and the environment-friendly shoe sole is environmentally friendly, so that requirements for environmentally friendly life are met.

Description

technical field [0001] The invention relates to the field of shoe materials, in particular to an environmentally friendly shoe sole and a manufacturing method thereof. Background technique [0002] Shoes are indispensable daily necessities in people's daily life. Their common function is to protect the feet from the damage of the external environment and ensure the safety of walking. As an important part of shoes, the soles are mainly used for The foot of the bearer acts as a cushioning protection. The existing soles are all made of EVA (ethylene-vinyl acetate copolymer), which has the advantages of good cushioning, shock resistance, heat insulation, moisture resistance, chemical corrosion resistance, bacteria prevention and waterproofing, etc. It is very in line with the performance requirements of the sole, but the disadvantage is that the pure EVA sole is not easy to degrade in the natural environment, and the environmental protection is not enough.
