Abstract

The invention relates to a method for making a surface layer of a polyvinyl chloride decorative sheet product. The method aims to solve the technical problems of poor scratch resistance, poor abrasion resistance and poor surface texture of the surface of the conventional polyvinyl chloride (PVC) decorative sheet product. The method for making the surface layer of the polyvinyl chloride decorative sheet product comprises the following steps of: 1) preparing polyurethane double-component synthetic coating into special base paint and special finishing paint in a certain weight ratio; 2) cleaning the surface of the PVC decorative sheet product; 3) spraying the cleaned surface by adopting a spray gun, drying the surface and then conveying the product to a polishing area, and performing surface flattening, sanding and rust removal treatment by adopting dry abrasive paper; and 4) spraying the base paint for the second time by the operating method, conveying the product to the polishing area, performing surface polishing and rust removal treatment by adopting the dry abrasive paper, conveying the product to a paint spraying room, spraying the PVC decorative sheet product by using a spray gun, drying the product and then transferring the product to an airing room, and naturally drying the product to form the surface layer. The method has the advantages of high production efficiency, good surface quality and the like.

Description
