Problems solved by technology

However, with the method of paint spraying, the metal effect produced on the surface of the shell is not obvious enough, and the metal layer is formed by physical or chemical deposition. Although the metal effect is strong, the adhesion between the formed metal layer and the plastic shell is weak, and the surface of the metal layer is resistant to corrosion. Poor scratch performance and high cost
In addition, due to the single color of the metal, it is difficult to bring colorful decorative effects to consumers.

Embodiment Construction

[0008] see figure 1 As shown, the housing 100 according to the preferred embodiment of the present invention includes a base 10 , a first decoration layer 12 disposed on the base 10 and a second decoration layer 14 disposed on the first decoration layer 12 .

[0009] The base body 10 can be a transparent plastic layer, which can be made by injection molding. The plastic forming the base body 10 can be selected from transparent plastics such as polymethyl methacrylate, polycarbonate or polystyrene. The substrate 10 can also be a glass layer, and the glass can be silicate glass, borate glass or phosphate glass. The base 10 includes an outer surface 101 and an inner surface 103 opposite to the outer surface 101 .

[0010] The first decoration layer 12 is a translucent ink layer with metallic luster, which is formed on the inner surface 103 of the substrate 10 by printing. The first decoration layer 12 contains acrylic urethane resin transparent ink components and materials wit...

Abstract

The invention relates to a shell which comprises a transparent basal body, a first decoration layer arranged on the transparent basal body and a second decoration layer arranged on the first decoration layer, wherein the first decoration layer is a semitransparent ink layer and contains matters with metal luster; and the second decoration layer is a color ink layer.

Description

technical field [0001] The present invention relates to a casing, in particular to a casing of a portable electronic device. Background technique [0002] With the improvement of consumption level, consumers not only pay attention to the quality of electronic products, but also pay more and more attention to the texture and decorative effect of the surface. Electronic products with metallic texture and colorful decorative effects are very competitive in the market . [0003] At present, the casings of portable electronic products such as mobile phones are usually made of plastic injection molding. In order to make the surface of the product have a metallic texture and luster, physical or chemical vapor deposition methods can be used to coat a metal layer on the casing after injection molding. Or spray paint containing components such as metal or mica to the formed shell. However, with the method of paint spraying, the metal effect produced on the surface of the shell is no...
