Abstract

The invention relates to a polyvinyl chloride foaming composition for manufacturing artificial leather, which comprises, by weight per 100 parts, 50-60 parts of PVC (anti-ultraviolet) resin, 35-50 parts of a plasticizer, 1-3 parts of a foaming agent, 2-7 parts of a stabilizer, 0.1-1 part of an essence, 0-6 parts of a pigment, and 0-3 parts of an adjuvant. The invention also provides artificial leather containing a PVC foam layer made with the polyvinyl chloride foaming composition, a method for preparing the artificial leather and application of the polyvinyl chloride foaming composition in manufacturing the artificial leather. The polyvinyl chloride foaming composition has the advantages that the odor grade of the prepared PVC artificial leather is successfully improved, the risk of forming defects on the surface layer of the artificial leather is avoided, the polyvinyl chloride foaming composition has no special limitation on foaming agents, and various physical foaming agents and chemical foaming agents suitable for the PVC artificial leather field can be used.

Description

technical field [0001] The present invention relates to a polyvinyl chloride foaming composition for making artificial leather. More specifically, the present invention relates to polyvinyl chloride foaming compositions for the manufacture of artificial leather for automotive interiors and similar articles. Background technique [0002] Polyvinyl chloride (ie PVC, hereinafter the terms "PVC" and "polyvinyl chloride" are used interchangeably) is the main raw material in the production and development of artificial leather. The paste made by adding plasticizers and stabilizers to PVC is easy to color. After the coating is gelled, it can be printed, embossed or embossed and printed to make a variety of products similar in appearance to leather. Artificial leather made of polyvinyl chloride has good strength and wear resistance, and is easy to produce, rich in raw materials, uniform in product quality, easy to cut and use, light in weight, water resistant, and low in cost, so i...
