A kind of PVC foamed artificial leather based on gypsum whiskers and preparation method thereof

Abstract

A gypsum whiskers-based PVC foaming synthetic leather and preparation method therefor, comprising a cloth base material, a foaming layer, and a surface layer. The foaming layer comprises the following components according to parts by weight: 95-105 parts of PVC resin, 40-50 parts of gypsum whiskers, 40-50 parts of calcium carbonate powder, 75-85 parts of a plasticizer, 3.5-4.0 parts of a stabilizer, 4.5-5.5 parts of a foaming agent, and 9.5-10.5 parts of color cakes. The surface layer comprises the following components according to parts by weight: 65-75 parts of PVC resin, 10-20 parts of gypsum whiskers, 46-52 parts of a plasticizer, 1.5-3 parts of a stabilizer, and 4.5-5.5 parts of color cakes. The preparation steps are as follows: (1) calcining; (2) dosing; (3) compounding, milling and filtering; (4) calendering and laminating; (5) foaming; and (6) embossing, cooling, and rolling; so that a gypsum whiskers-based PVC foaming synthetic leather finished product is obtained.

Description

technical field [0001] The invention relates to PVC foamed artificial leather based on gypsum whiskers and a preparation method thereof. Background technique [0002] At present, with the rapid development of the clothing industry, people are very enthusiastic about the pursuit of leather clothing, but the price of genuine leather leather clothing is high and difficult to maintain, so the demand for artificial leather and synthetic leather is gradually increasing, and due to the softness of PU synthetic leather Good texture and strong three-dimensional characteristics, so it is widely used in the manufacture of leather clothing. In the synthetic leather industry, a large part of PU synthetic leather is processed by wet kneading process, but with the hydrolysis of PU synthetic leather, the product price is relatively expensive and technical problems such as the inability to produce coarse grain products have appeared. Since 2005 The production of domestic PU synthetic leathe...

Problems solved by technology

Generally, when utilizing PVC to prepare the leather foam layer, some fillers, such as calcium carbonate powder, etc., can be added. The fillers mainly serve to increase the stability of the product size and reduce the cost. However, at present, the artificial leather prepared by PVC resin has poor elasticity, Not wear-resistant, poor corrosion resistance and acid resistance
