Embodiment Construction

[0021] see figure 1 According to a preferred embodiment of the present invention, the housing 10 of the electronic device includes a base 11 and a primer layer 13 , a metal texture layer 15 , a middle paint layer 17 and a top paint layer 19 sequentially formed on the surface of the base 11 .

[0022] The base body 11 can be a plastic base body, which can be made by injection molding. The plastics for injection molding the matrix 11 can be selected from polycarbonate (PC), polyethylene (PE), polymethyl methacrylate (PMMA) and polycarbonate and acrylonitrile-styrene-butadiene copolymer. Any of the mixture (PC+ABS). The substrate 11 can also be a glass substrate or a ceramic substrate.

[0023] The primer layer 13 can be formed by spraying polyurethane paint on the surface of the substrate 11 . The primer layer 13 is a colorless and transparent paint layer, which has a smooth and even surface, which can enhance the bonding force between subsequent coatings and the primer layer...

Abstract

The invention provides a housing of an electronic device, which comprises a base body and a metal texture layer and a finish layer orderly formed on the surface of the base body. The metal texture layer is a non-conducting layer formed by means of vacuum coating and is a compound layer stacked alternately by multiple titanium oxide layers and silicon dioxide layers. The reflectivity of the metal texture layer is 50-80%. The finish layer contains magic pearlescent pigments. The housing of the electronic device has magic pearlescent and metal texture appearance. The invention further provides a preparation method of the housing of the electronic device.

Description

technical field [0001] The invention relates to an electronic device casing and a manufacturing method thereof, in particular to an electronic device casing with a pearlescent and metallic appearance and a manufacturing method of the electronic device casing. Background technique [0002] The casings of existing electronic products (such as mobile phones, PDAs, etc.) are often coated with a metal layer or a metal oxide layer to make the product have a metallic texture, thereby attracting consumers' attention. The metal layer is usually formed by non-conductive plating, because the metal layer is non-conductive, thereby preventing it from interfering with signals. The non-conductive metal layer or metal oxide layer is usually transparent, and after it is formed on the shell, together with the base material of the shell or other paint layers formed on the shell, the shell presents a colored metallic Textured look. [0003] However, although the above casing has a colorful me...
