Preparation process of EVA composite sole

Abstract

The invention discloses a preparation process of an EVA composite sole. The surface layers of adjacent shoe pieces of an EVA antibacterial and wear-resistant layer shoe piece, an EVA elastic and folding-resistant layer shoe piece and an EVA wear-resistant and slip-resistant layer shoe piece are heated and melted, then the adjacent shoe pieces are bonded together through a pressing mold, and the EVA composite sole with the EVA antibacterial and wear-resistant layer shoe piece, the EVA elastic an folding-resistant layer shoe piece and the EVA wear-resistant and slip-resistant layer shoe piece arranged on the upper layer, the middle layer and the lower layer correspondingly is finally formed. Due to the fact that the same EVA base material is adopted for bonding, when increasing influences of sunlight, temperatures and the like happen, the situation that the bonding position qualitatively changes, and consequently a shoe is damaged is not prone to happening, the overall structural strength is high, and the service life is long. The produced EVA composite sole has the composite performance of antibacterial performance, wear resistance, elasticity, folding resistance, wear resistance and slip resistance, and the EVA antibacterial and wear-resistant layer on the surface layer is not prone to breeding germs in a relatively warm and humid environment in summer when feet of a wearer sweat during sports.

Description

technical field [0001] The invention relates to the technical field of EVA shoe materials, in particular to a preparation process for EVA composite shoe soles. Background technique [0002] EVA is a copolymer of ethylene and acetic acid, and its Chinese chemical name is ethylene-vinyl acetate copolymer (ethylene-vinyl acetate copolymer). Generally, the content of vinyl acetate (VA) is 5-40%. Compared with polyethylene (PE), EVA reduces high crystallinity and improves toughness, impact resistance, Filler compatibility and heat sealing properties. EVA is widely used in a wide range of applications, and the annual market consumption in my country is constantly increasing, especially in the shoe industry, where it is used in the soles and interior materials of mid-to-high-end travel shoes, hiking shoes, slippers, sandals. In a relatively warm and humid environment in summer, the wearer will sweat a lot during exercise. After a long time, the inside of the sports shoes will acc...

AI Technical Summary

Problems solved by technology

In a relatively warm and humid environment in summer, the wearer will sweat a lot during exercise. After a long time, the inside of the sports shoes will accumulate sweat stains and stink. EVA slippers are easy to breed bacteria, which can only be removed by washing or exposure to the sun. Smelly, cumbersome, and lacking in other properties such as abrasion resistance, slip resistance, and light weight
