Abstract

The invention relates to the technical field of synthetic leather, and provides a preparation method of organosilicone synthetic leather. The method comprises the steps that 1, surface glue is prepared; 2, bottom glue is prepared; 3, release paper is evenly covered by the surface glue through a roller painter according to thickness of 0.1-0.5 mm to obtain a surface glue layer, drying is conducted,on a second roller painter, according to thickness of 0.1-0.2 mm, the surface glue layer is evenly covered by a bottom glue material, then the surface glue layer and a base cloth are subjected to lamination, drying is conducted, and through a winder, the release paper of a semi-finished product is separated, so that the organosilicone synthetic leather is obtained. By means of the preparation method of the organosilicone synthetic leather, the problems that existing organosilicone synthetic leather is prone to generate static electricity and has poor bonding fastness are solved.

Description

technical field [0001] The invention relates to the technical field of synthetic leather, in particular to a method for preparing organic silicon synthetic leather. Background technique [0002] Silicone synthetic leather is a composite material composed of textile (or synthetic leather) base material, primer glue, surface glue and surface coating layer, etc. bonded in sequence. Compared with the very popular and best-selling polyurethane synthetic leather in the market, silicone synthetic leather has not achieved substantial promotion. The fundamental reason is the excellent cost performance of polyurethane synthetic leather. However, polyurethane synthetic leather always has defects in toxicity, environmental protection, weather resistance and water resistance, while silicone materials have environmental protection, weather resistance and hydrophobic properties, so silicone synthetic leather has always been regarded as a potential value. alternatives. Although silicone s...
