Embodiment Construction

[0017] see figure 1 A housing 10 according to a preferred embodiment of the present invention includes a substrate 11 and a primer layer 13 , a metal layer 15 and a topcoat layer 17 sequentially formed on the surface of the substrate 11 .

[0018] The base material 11 is made of plastic material.

[0019] The primer layer 13 is a transparent UV-curable resin layer, specifically an acrylic epoxy resin. The curing degree of the primer layer 13 is 50%-85%, and its thickness is 5-30 μm.

[0020] The metal layer 15 is a translucent layer, which can be formed by vacuum sputtering. The metal layer 15 is a silicon aluminum alloy layer with a thickness of 10-80 nm. The atomic percentage of silicon in the metal layer 15 is 10-90%, and the atomic percentage of aluminum is 90-10%.

[0021] The topcoat layer 17 is a transparent layer, which can protect the metal layer 15 from abrasion and scratches. The specific composition of the topcoat layer 17 can be acrylic polyurethane. The thi...

Abstract

The invention relates to a housing comprising a substrate. A primer layer, a metal layer and a topcoat layer are sequentially formed on the surface of the substrate. The primer layer is an acrylic epoxy resin layer. The metal layer is a silicon-aluminum alloy layer. Silicon atomic percentage in the metal layer is 10-90%, and aluminum atomic percentage in the metal layer is 90-10%. The topcoat layer is an acrylic polyurethane layer. The surface of the housing has a colorful effect, and has bright colors and a good metal texture. The invention also provides a preparation method of the housing.

Description

technical field [0001] The invention relates to a casing and a preparation method thereof. Background technique [0002] In order to make the casing of the electronic device have an attractive appearance, currently the decorative coating is mainly prepared by anodic oxidation, baking paint spraying and other processes. However, the decorative coatings formed by these processes often lack metallic texture, and the decorative coatings often can only present a single color effect, resulting in weak product competitiveness. Contents of the invention [0003] In view of this, it is necessary to provide a housing that effectively solves the above problems. [0004] In addition, it is also necessary to provide a method for preparing the above shell. [0005] A shell, which includes a substrate, a primer layer, a metal layer and a topcoat layer formed on the surface of the substrate in sequence, the primer layer is an acrylic epoxy resin layer; the metal layer is a silicon alumi...
