Problems solved by technology

[0004] The coating methods of the three types of substrates are difficult to use with each other. For example, if ordinary PVD coating is used on glass, although a film layer with better appearance and performance can be obtained, the film layer is conductive and will interfere with mobile phone signals.
Using ordinary PVD coating on plastic, the adhesion of the film layer is very poor. In addition, the heating in the coating has the risk of causing deformation of the plastic.
Using NCVM technology on glass and metal, the product has a heavy paint feel, and the metal texture is not strong enough, which affects the appearance of the product

Embodiment 1

[0082] (1) The stainless steel is processed and formed, polished and polished, microporous treatment, and film treatment are sequentially performed to obtain a stainless steel substrate frame; wherein, the microporous treatment conditions include: soaking the substrate in a 30% by weight sulfuric acid solution, Soak for 90 minutes at 40°C for pretreatment to form irregular corrosion holes on the stainless steel substrate; then, the stainless steel substrate was taken out, washed with water, and then placed in a 25% by weight sodium hydroxide solution, with carbon plate As the cathode, the stainless steel substrate is used as the anode, and it is energized for 2 minutes at a voltage of 5V for electrochemical corrosion, taken out, washed and dried;

[0083] (2) Put the injection molding compound (mixed polyamide and glass fiber at a weight ratio of 2:1) into an oven to preheat to 250°C, and place the glass cover (Corning third-generation Gorilla Glass cover) by injection molding at ...

Embodiment 2

[0087] (1) The stainless steel is processed, formed, polished and polished, microporous treatment and filming treatment are carried out in sequence to obtain a stainless steel substrate frame; wherein the microporous treatment conditions include: immersing the substrate in a 40% by weight sulfuric acid solution, Soak for 120 minutes at 40°C for pretreatment to form irregular corrosion holes on the stainless steel substrate; then, take out the stainless steel substrate, wash it with water, and put it in a 30% by weight sodium hydroxide solution, and use a carbon plate As the cathode, the stainless steel substrate is used as the anode, and the electrochemical corrosion is carried out by electrifying for 3 minutes at a voltage of 3V, taking it out, washing and drying;

[0088] (2) Put the injection molding compound (mixing polyamide and glass fiber at a weight ratio of 1:1) into an oven to preheat to 300°C, and place the glass cover (Corning's third-generation Gorilla Glass cover) by...

Embodiment 3

[0092] The shell product C3 was prepared according to the method of Example 1, except that the injection molding compound was polycarbonate and glass fiber mixed in a weight ratio of 2:1. The obtained shell product C3 has good consistency and good metal texture.

Abstract

The invention relates to the technical field of electronic products, and discloses a shell, a film coating method of the shell and an electronic product comprising the shell. The shell comprises a shell body, a metal oxide layer formed on the surface of the shell and a metal layer formed on the metal oxide layer, wherein the shell body comprises a glass cover plate, a plastic frame body and a metal base material frame, and the glass cover plate, the plastic frame body and the metal base material frame are integrally formed. According to the shell, the appearance has relatively good consistencyand good metal texture, and the performance is excellent.

Description

Technical field [0001] The present invention relates to the technical field of electronic products, in particular to a housing and a coating method thereof and an electronic product. Background technique [0002] At present, the assembly of glass and metal middle frame of mobile phone glass shells on the market usually adopts a bonding method. The glass and metal middle frame can be respectively finished after finishing the surface decoration and then assembled. The surface decoration methods of the glass include the application of explosion-proof decorative film, screen printing ink, optical coating, etc. The surface decoration method of the metal middle frame depends on the metal material. There are spraying, anodizing, PVD vacuum coating, etc. [0003] The vacuum coating that achieves the metallic texture on the glass substrate is an optical decorative coating, which mainly displays the desired color and texture by alternately superimposing the coating of high and low refractiv...
