Embodiment Construction

[0029] The present invention will be further described below in conjunction with accompanying drawing:

[0030] With reference to accompanying drawing: the preparation technology of a kind of EVA composite sole in the present embodiment is characterized in that: comprise the following steps,

[0031] Step 100, preparing the EVA antibacterial wear-resistant layer shoe piece;

[0032] Step 200, preparing the EVA elastic fold-resistant shoe piece;

[0033] Step 300, preparing the EVA wear-resistant anti-slip layer shoe;

[0034]Step 400, heat and melt the adjacent shoe surface layers of the EVA antibacterial wear-resistant layer shoe, EVA elastic fold-resistant layer shoe, and EVA wear-resistant anti-slip layer shoe, and then press the mold 1 to make the adjacent shoe pieces Bonded together, the final shape is an EVA composite sole with the upper, middle and lower layers being the EVA antibacterial wear-resistant layer shoe piece, the EVA elastic fold-resistant layer shoe piece...

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...
