Mildew-proof wear-resistant environment-friendly PVC artificial leather and preparation method thereof

Abstract

The invention relates to mildew-proof wear-resistant environment-friendly PVC artificial leather and a preparation method thereof. The PVC artificial leather comprises a base cloth layer and a PVC surface layer attached to the base cloth layer. The PVC surface layer is prepared from the following raw materials in parts by weight: 100 parts of PVC resin, 20-30 parts of a functional elastomer, 50-70 parts of a plasticizer, 12-20 parts of coconut shell powder modified vermiculite powder, 4-12 parts of a cross-linking agent, 1-5 parts of a heat stabilizer, 1-3 parts of an antibacterial agent and 0.2-4 parts of a foaming agent. Compared with the prior art, the PVC artificial leather disclosed by the invention does not contain any volatile solvent, is good in environmental protection property, smooth in hand feeling, strong in stereoscopic impression and high in glossiness quality, has excellent mould-proof, antibacterial and wear-resistant scratching properties, is plump in hand feeling like real leather, has physical properties reaching test standards, and is long in service life; the problems that existing PVC leather is prone to aging, mildewing, peeling and the like can be effectively solved, and high economic practicability is achieved.

Description

technical field

[0001] The invention belongs to the technical field of leather processing, and relates to a mildew-proof, wear-resistant and environment-friendly PVC artificial leather and a preparation method thereof. Background technique

[0002] Artificial leather is also called imitation leather or rubber, which is a plastic product that looks and feels like leather and can be used instead of it. Artificial leather is usually made of different formulations of PVC or PU foamed or coated on a woven or non-woven fabric base. It has the characteristics of a wide variety of designs and colors, good waterproof performance, neat edges, high utilization rate and relatively cheap price compared with real leather.

[0003] At present, for PVC artificial leather products, there are mainly the following problems: First, due to the need to use some volatile processing aids (such as plasticizers) in the processing process, the final PVC artificial leather products often have certai...
