Abstract

The invention relates to the field of synthetic leather production, and especially relates to a PVC artificial leather and its preparation method. The preparation method of the PVC artificial leather comprises the following steps: 1, preparing materials; 2, coating release paper with a prepared PVC surface slurry to form a PVC surface layer; 3, coating the PVC surface layer with a prepared PVC foaming slurry to form a PVC foam layer; 4, coating the PVC foam layer with a prepared polyurethane adhesive to form a polyurethane adhesion layer and a base cloth layer; 5, removing the release paper; 6, carrying out roller coating on the surface of leather by using a prepared polyurethane treatment agent; and 7, drying, and carrying out cooling molding to form the PVC artificial leather. Compared with present products, the PVC artificial leather prepared through the method, having the PVC surface layer, has the advantages of increased bending strength and scraping resistance, firm handfeel and good physical properties, and can resist bending 100000 times.

Description

technical field [0001] The invention relates to the field of synthetic leather manufacture, in particular to a PVC artificial leather and a preparation method thereof. Background technique [0002] The previous PVC artificial leather is composed of polyvinyl chloride foam layer, polyvinyl chloride adhesive layer and base cloth layer as a whole. The specific preparation method is as follows: [0003] Step 1, material preparation: prepare polyvinyl chloride foaming slurry; prepare polyvinyl chloride adhesive; select base cloth and release paper; [0004] Step 2. Coat the prepared polyvinyl chloride foaming slurry on the release paper, enter the oven, and control the temperature of the oven at 170-190 degrees to form a polyvinyl chloride foaming layer after foaming; [0005] Step 3. Coat the prepared polyvinyl chloride adhesive material on the polyvinyl chloride foam layer, then glue the selected base cloth, and dry it in an oven. The temperature of the oven is controlled at 1...
