Abstract

The invention discloses a production process of fluorine-free environment-friendly sports shoe synthetic leather, which specifically comprises the steps: preparing a fluorine-free wet base coating material, a fluorine-free wet base impregnation material and a dry top material according to a formula, impregnating a nonwoven fabric into the wet base impregnation material, scraping to apply the wet base coating material onto the surface of the nonwoven fabric, solidifying in a solidification tank to form a film, extruding, washing, and baking and setting to form a wet base; scraping to apply a mixed solution of the dry top material onto release paper, bonding the wet base through a fluorine-free adhesive, and separating the release paper a finished product. The environmental damage due to theuse of conventional fluorine hydrolysis-resistant resin is eliminated, the synthetic leather produced herein is soft to touch, and has excellent elasticity, high peeling strength and high hydrolysisresistance.

Description

technical field [0001] The invention relates to the field of synthetic leather manufacturing, in particular to a production process of fluorine-free and environment-friendly synthetic leather for sports shoes. Background technique [0002] At present, in order to improve the hydrolysis resistance of synthetic leather, the production process is made of hydrolysis-resistant resin containing fluoropolyether. Although this traditional production process improves the hydrolysis resistance of synthetic leather to a certain extent, it does not The production and use of this kind of synthetic leather will produce fluorocarbon emissions, which will cause environmental pollution and affect human health. Contents of the invention [0003] In order to overcome the above defects, the present invention provides a fluorine-free and environment-friendly synthetic leather production process for sports shoes. The material used in the process is fluorine-free resin, which avoids environmenta...
