Method for producing hyperfine texture decorative metal plate and hyperfine texture decorative metal plate

Abstract

The invention provides a method for producing a hyperfine texture decorative metal plate. The method comprises the following technical processes: uncoiling a substrate, pretreating the substrate, coating the substrate by using a back paint and a priming paint, coating the substrate by a floating coat, producing a first forming layer, producing a second forming layer, laminating a protection film, and rolling; wherein, the second forming layer employs a mold film for embossing molding. The invention also provides a hyperfine texture decorative metal plate which comprises a base plate, wherein a chemical treatment layer and a back paint layer are sequentially arranged on the lower surface of the base plate; another chemical treatment layer, a priming coat layer, a middle coating layer, the first forming layer and a second forming layer are sequentially arranged on the upper surface of the base plate from bottom to top. The width of the texture of the metal plate produced by the embossing molding method is within 5-1000 [mu]m, the metal plate has hyperfine texture, concave-convex touch feeling and a variable pattern effect and is relatively low in cost and high in production efficiency, and raw materials used in the metal plate are all non-toxic and pollution-free environment-friendly raw materials.

Description

technical field [0001] The invention belongs to the technical field of manufacturing colored metal plates for home appliance appearance, home decoration and architectural decoration such as high-grade elevators. Specifically, it relates to a method for preparing a superfine texture decorative metal plate and the metal plate. Background technique [0002] Existing textured decorative metal plates are generally produced by printing techniques, including screen printing and gravure transfer printing. No matter which printing process is used, the preparation of ultra-fine textures on the surface of the metal plate cannot be realized. [0003] The preparation of the textured decorative metal plate is realized by using the film coating process. The main method is to laminate the PET+PVC color film on the substrate with a special glue. The general structure of PET+PVC laminated color film is as follows: a pattern layer is pressed on the top of the PET film, followed by a color laye...
