Abstract

The invention relates to flame-retardant antibacterial environment-friendly PVC artificial leather which comprises a base cloth layer, a middle layer and a PVC surface layer. The base cloth layer andthe middle layer are bonded through a bonding layer, the middle layer is a smoke-inhibiting flame-retardant layer, a PVC foaming layer coats the middle layer, a surface treatment agent coats the PVC foaming layer, and the PVC surface layer is formed after the surface treatment agent is cured; an environment-friendly layer coats the PVC surface layer. By arranging a bacteriostatic flame-retardant layer and the environment-friendly layer, PVC has excellent flame-retardant and antibacterial performance. In addition, waterborne polyurethane resin is adopted to replace conventional solvent-type polyurethane, so that the problem of serious environment protection in the process of solvent-type synthetic leather is solved effectively.

Description

technical field [0001] The invention belongs to the technical field of textiles, and in particular relates to a flame-retardant, antibacterial and environment-friendly PVC artificial leather. Background technique [0002] Artificial leather is also called imitation leather or rubber, which is a general term for artificial materials such as PVC and PU. It is made of different formulations of PVC and PU foamed or coated on a woven cloth base or a non-woven base. Patterns and other requirements are processed, and 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] Today, artificial leather has been produced in large quantities and used in materials including clothing, shoes, furniture and vehicles. The manufacture of artificial leather generally uses non-woven fabrics made of general fibers, superfine fibers or general fibers and super...
