Embodiment Construction

[0013] The preferred embodiment of the present invention plastic surface treatment method comprises the following steps:

[0014] First, a plastic base is provided. A rough area is preset at the position where the matte surface is pre-formed on the surface of the substrate, and the rough area can be any figure, sign or text. The material of the matrix can be acrylonitrile-butadiene-styrene (ABS), polycarbonate (polycarbonate, PC), acrylonitrile-butadiene-styrene and polycarbonate mixture and polycarbonate Polyethylmethacrylate (PMMA) and other plastic materials that can be injection molded. The plastic base body is formed by injection molding and has a predetermined shape. The rough area can be obtained by setting a corresponding rough area at a corresponding position in the mold cavity of the injection mold when the plastic base is injected.

[0015] Thereafter, a primer layer is sprayed on the surface of the substrate, and the primer is an ultraviolet curing paint. The p...

Abstract

The invention provides a method for processing a plastic surface; comprising the following steps: providing a plastic base body, wherein the surface of the plastic base body is previously provided with a rough area; spraying a priming paint layer on the surface of the plastic base body; forming a vacuum plating film layer on the surface of the priming paint layer; spraying a transparent middle paint layer on the surface of the vacuum plating film layer; and spraying a transparent finish paint layer on the surface of the middle paint layer. By the method for processing the plastic surface, theplastic surface t can not only achieve bright metal appearance but also can show obvious bright and matte double-color effect.

Description

technical field [0001] The invention relates to a plastic surface treatment method, in particular to a surface treatment method for producing bright-dumb double-color and metallic texture on the plastic surface. Background technique [0002] Due to the characteristics of easy molding and light weight, plastics are widely used in the manufacture of electronic product appearance parts. As people have higher and higher requirements for the appearance quality and aesthetics of decorative appearance parts, people are no longer satisfied with the color of the plastic itself or the single, dull color obtained by simple spray painting. The shiny texture of metal is seen on the plastic surface. In order to obtain a metal appearance on the plastic surface, various plastic appearance parts are usually subjected to surface treatments such as electroplating or painting. [0003] Among them, the electroplating solution used in the electroplating method contains more toxic substances, wh...
