Preparation method for night self-luminous mobile phone shell

Abstract

The invention relates to a preparation method for a night self-luminous mobile phone shell, and belongs to the technical field of electronic products. The preparation method comprises the following steps: mixing a plastic substrate, fluorescent powder and a dye according to a proportion, carrying out stirring to obtain a mixture, heating and melting the mixture to obtain a liquid material, throwing the liquid material into a screw extruder, feeding the material in the screw extruder into an injection molding machine through a pressurizing pump, injecting the material into a mobile phone mold for molding; sequentially spraying a primer and a colored paint, then carrying out vacuum coating, and removing the vacuum coated film in an area, where a colored paint layer needs to be displayed, onthe vacuum coating layer by laser radium carving. After the vacuum coating, a middle paint layer and a UV surface paint layer are sequentially formed on the surface of the coating film. The preparation theory is clear; the method is scientific; the mobile phone shell prepared by the method provided by the invention has exquisite texture, rich color, good color gradation and good visual effect; themobile phone is convenient to find at night; and convenient use for people is obtained.
