A kind of PVC foam artificial leather and preparation method thereof

Abstract

The invention discloses PVC (polyvinyl chloride) foamed artificial leather and a preparation method thereof. The PVC foamed artificial leather comprises a fabric base material, a foaming layer and a surface layer which are attached from inside to outside sequentially, wherein the foaming layer comprises components in parts by weight as follows: 95-105 parts of PVC resin, 75-85 parts of filling 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 masterbatch; the surface layer comprises components in parts by weight as follows: 65-75 parts of PVC resin, 6-8 parts of filling powder, 46-52 parts of a plasticizer, 1.5-3 parts of a stabilizer and 4.5-5.5 parts of masterbatch. The preparation method comprises steps as follows: (1), blending; (2), mixing, open milling and filtering; (3), calendering attachment; (4), cooling; (5), foaming; (6), embossing, cooling and rolling-up to obtain a finished PVC foamed artificial leather product. The artificial leather prepared with the method feels good, and is good in texture, high in breathability and good in wear resistance.

Description

technical field [0001] The invention relates to PVC foamed artificial leather and a preparation method thereof. Background technique [0002] At present, with the rapid development of the automobile industry and the furniture industry, the demand for artificial leather and synthetic leather is increasing rapidly. Due to the softness of the handle and the strong three-dimensional texture of PU synthetic leather, it is widely used in sofa furniture. and car interiors. 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 leather has a certain degree of decline every year. At present, PVC has been widely used in the automobile industry and furniture industry, and cost control can be achieve...

Problems solved by technology

Generally, when using PVC to prepare the leather foam layer, some fillers, such as calcium carbonate powder, etc., are added. The fillers are mainly used to increase the stability of the product size and reduce the cost. Rarely, generally, the amount of filler used will be less than 70% of the weight of PVC. The main reason is that adding too much filler will affect the texture and foaming effect of the product, so it restricts the use of fillers, but it is often ignored. It improves the function of the filler on the wear resistance of the product; moreover, in the prior art, no filler is set in the surface layer to prevent affecting the softness of the surface layer
