Abstract

The invention relates to hydrolysis-resistant artificial leather. The hydrolysis-resistant artificial leather comprises a surface layer, a middle layer and a foaming layer which are sequentially arranged. The surface layer is prepared from, by weight, 95-105 parts of hydrolysis-resistant resin, 50-70 parts of organic solvent, 5-10 parts of aging-resistant auxiliary and 3-7 parts of PU color paste. The hydrolysis-resistant resin is polyether or a polyether compound. The middle layer is prepared from, by weight, 95-105 parts of polyvinyl chloride resin, 60-70 parts of diisononyl phthalate and 4-7 parts of PVC color paste. The foaming layer is prepared from, by weight, 100 parts of polyvinyl chloride resin, 75-85 parts of diisononyl phthalate, 50-70 parts of filler and 3-5 parts of PVC color paste. The invention further relates to a preparation method of the hydrolysis-resistant artificial leather. The hydrolysis-resistant artificial leather can remarkably improve the hydrolysis-resistant performance of the surface layer, and has the advantage that the surface is not prone to disengagement.

Description

technical field [0001] The invention relates to artificial leather technology, in particular to a hydrolysis-resistant artificial leather and a preparation method thereof. Background technique [0002] The hydrolysis-resistant artificial leather in the prior art includes a surface layer, a middle layer, a foam layer, an adhesive layer and an artificial leather base cloth, and the artificial leather base cloth is adhered to the side of the adhesive layer away from the foam layer. Among them, the raw material design of 100 parts of polyurethane resin (polyester type), 80-100 parts of organic solvent and 3-7 parts of PU color paste is used as the surface layer; 100 parts of polyvinyl chloride resin, dioctyl phthalate 50-60 parts of ester, 1-2 parts of BaZn and 4-7 parts of PVC color paste are designed as the middle layer; 100 parts of polyvinyl chloride resin, 70-80 parts of dioctyl phthalate, 50 parts of filler -70 parts, 2-3 parts of auxiliary agent (KZn), 3-4 parts of foami...
