Abstract

The invention belongs to the technical field of leather and more specifically relates to PVC synthetic leather for automotive interior. The PVC synthetic leather comprises a PVC base layer, a first adhesion layer, an antibacterial layer, a second adhesion layer, an ultraviolet-proof layer, a third adhesion layer and a wear-resistant layer sequentially, wherein the antibacterial layer comprises thecomponents by weight as follows: 90%-98% of PVC resin, 0.1%-5% of chitosan and 0.1%-5% of a nano-silver antibacterial agent, the degree of deacetylation of the chitosan is 85%-95%, and the molecularweight of the chitosan is 0.1-0.2 million. Compared with the prior art, the PVC synthetic leather can have a good antibacterial effect by means of the antibacterial layer. Meanwhile, the ultraviolet-proof layer is arranged, so that the ultraviolet resistance of the synthetic leather can be improved, and the aging resistance of the synthetic leather can be improved; the PVC synthetic leather is endowed with good wear resistance and scratch resistance by means of the wear-resistant layer.

Description

technical field [0001] The invention belongs to the technical field of leather, more specifically, the invention relates to a PVC synthetic leather for automobile interior decoration. Background technique [0002] With the development of synthetic leather technology, PVC synthetic leather has been used to replace natural leather in most areas of life due to its characteristics of various performance materials close to natural leather. Due to the development of various industries, customers have higher and higher requirements for products. Common PVC leather, due to the characteristics of the product itself, has poor air permeability, is easy to mold, and breeds the growth of bacteria simultaneously, and the PVC in the prior art has poor wear resistance and poor aging resistance, so it cannot be used as an automotive interior material. [0003] In view of this, the present invention aims to provide a PVC synthetic leather for automotive interiors, which has the function of a...
