Abstract

The invention discloses antibacterial and antiviral polyvinyl chloride artificial leather. The antibacterial and antiviral polyvinyl chloride artificial leather comprises a base cloth layer, an antibacterial PVC layer and an antiviral coating layer. The preparation raw materials of the antibacterial PVC layer comprises, by mass, 30-70 parts of PVC resin, 20-50 parts of plasticizer, 1-5 parts of stabilizer, 1-5 parts of modifier, 0.5-10 parts of antibacterial mildew preventive and 0-2 parts of foaming agent, wherein the antibacterial mildew preventive is a composite antibacterial mildew preventive formed in a manner that silicon dioxide coated silver nanoparticles of a core-shell structure and carboxymethyl chitosan are compounded. The preparation raw materials of the antiviral coating layer include 100 parts of acrylate emulsion, 0.1-5 parts of hollowed zinc oxide, 0.1-5 parts of graphene oxide, 0.1-1 part of antifoaming agent, 0.1-2 parts of flatting agent and 20-30 parts of deionizedwater. The prepared artificial leather is good in air permeability, excellent in mechanical performance and high in product grade, and has lasting and excellent antibacterial antimould effects and antiviral effects.

Description

technical field [0001] The invention belongs to the technical field of artificial leather, in particular to an antibacterial and antiviral polyvinyl chloride artificial leather and a preparation method thereof. Background technique [0002] Since the 1990s, as the first generation of artificial leather, polyvinyl chloride (PVC) artificial leather products have been gradually replaced by polyurethane (PU) artificial leather due to their shortcomings such as poor air permeability, moisture absorption, inability to recycle, and failure to meet environmental protection requirements. Artificial leather dropped from almost 100% market share to less than 40%. However, in recent years, due to the rising price of PU artificial leather raw materials, coupled with some problems such as poor hydrolysis resistance and weather resistance, the advantages of PVC artificial leather such as hydrolysis resistance, abrasion resistance, scratch resistance, acid and alkali resistance, and flame r...
