Example Embodiment

[0028] Method Example 1

[0029] A surface treatment method of an electronic product housing includes the following steps:

[0030] 1) Spray primer on the shell surface; the primer is UV transparent paint (Ultraviolet Curing Paint, called ultraviolet curing paint), the thickness of the primer is 25-30um, the baking temperature is 55±5°, and the baking energy of UV paint is 600 -800mj / cm2.

[0031] 2) A metal coating is formed on the primer by vacuum coating; the vacuum coating adopts the NCVM process (Nonconductive vacuum metallization, called non-conductive vacuum plating). The vacuum coating is to dissolve the target material to be plated by direct heating or indirect heating under vacuum conditions, and then evaporate, or directly sublimate the solid into a gas, and atoms or molecules with sufficient energy fly to and deposit on the bottom On the lacquer surface, a metal film of a certain thickness is deposited.

[0032] 3) The texture is formed by laser engraving on the metal co...

Abstract

The invention provides a surface treatment method for an electronic product shell. The method can form a color gradient effect on the shell surface. The method comprises the following steps: (1) spraying primer on the shell surface; (2) forming a metal coating film on the primer through vacuum coating; (3) forming texture on the metal coating film through laser etching; (4) spraying a first kind of color adding paint, and forming a first color layer with the thick middle and two thin edges on the metal coating film; (5) spraying a second kind of color adding paint, and forming a second color layer with the thin middle and two thick edges on the metal coating film, wherein the second color layer covers the first color layer; (6) spraying varnish. The first color adding paint is different from the second color adding paint in color. The method can realize a gradient color coating effect on the same shell and has the advantages of being easy to operate, less in technological process and low in cost.

Description

technical field [0001] The invention relates to an electronic product casing and a surface treatment method thereof. Background technique [0002] At present, the vacuum coating treatment process on the surface of the shell of electronic products only forms a single color on the surface of the shell, and cannot form a gradient appearance effect on the surface of the shell. Contents of the invention [0003] The purpose of the present invention is to provide a simple and easy method for treating the surface of the casing of an electronic product, which can form a gradient color effect on the surface of the casing. [0004] To achieve the above object, the present invention adopts the following technical solutions: [0005] A method for surface treatment of an electronic product housing, comprising the steps of: [0006] 1) Spray primer on the shell surface; [0007] 2), forming a metal coating on the primer by vacuum coating; [0008] 3), forming textures on the metal c...
