EVC shoe sole with PU composite film covered on its surface and its manufacturing method

Abstract

The invention discloses an EVC shoe sole with PU composite film covered on its surface, which comprises a shoe sole; a composite film main body is arranged on the shoe sole; a first film layer and a second film layer are arranged on the composite film main body, and the first film layer is arranged at the outermost layer of the composite film main body and bonded with the composite film main body;the second film layer is located between the composite film main body and the shoe sole and bonded to the composite film main body and the shoe sole. The invention designs a PU composite film bondedwith EVA; the film structure is divided into two layers, we can describe it after the film is bonded and shaped with the EVA. One layer of the outermost layer exposed in the air directly is PU resin layer, and the layer is acted on making the whole film layer resist high temperature better; the second layer is a hot sol layer, and the layer is acted on bonding with the EVA sole more firmly. The whole film in this design can well solve the core problem of the PU and the EVA bonding.

Description

technical field [0001] The invention relates to the technical field of shoe materials, in particular to an EVA shoe sole whose surface is covered with a PU composite film and a manufacturing method thereof. Background technique [0002] Traditional EVA soles have many disadvantages. Such as rough surface, insufficient wear resistance, dull surface, etc. In today's era of pursuing quality of life, the competitiveness of traditional EVA soles will become smaller and smaller. Therefore, finding a kind of method that solves the shortcoming of EVA shoe sole is very necessary for the stable development of EVA shoe sole. PU materials have excellent properties such as wear resistance, temperature resistance, sealing, good processing performance, and degradability. Moreover, the surface of PU is smooth after scraping and molding, and the appearance can be adjusted in a large space. These advantages of PU can perfectly make up for the shortcomings of EVA soles, but the current pro...
