Problems solved by technology
[0003] However, the inventors have found that at least the following problems exist in the prior art: most of the side buttons or camera decorations of mobile phones are made of plastic materials, and the overall color effect is consistent, requiring that the side buttons and camera decorations also need to be anodized. The same dark color usually adopts the non-conductive plating technology NCVM, but when it is made into a dark color, it is prone to the problem of paint peeling

Embodiment Construction
[0019] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, various implementation modes of the present invention will be described in detail below in conjunction with the accompanying drawings. However, those of ordinary skill in the art can understand that, in each implementation manner of the present invention, many technical details are provided for readers to better understand the present application. However, even without these technical details and various changes and modifications based on the following implementation modes, the technical solution claimed in this application can also be realized.
[0020] A first embodiment of the present invention relates to a material surface treatment method. The materials are usually shells that need surface spraying, such as mobile phone shells, PAD shells, etc. This implementation is mainly for non-conductive electroplating NCVM for dark-colored materials. NCVM ...

Abstract
The embodiment of the invention relates to the technical field of film coating and discloses a material surface treatment method and a shell. The material surface treatment method comprises the stepsthat priming paint is sprayed to a material, and a priming paint layer is formed, wherein the color lightness of the material is lower than a preset threshold; NCVM film coating is carried out on thepriming paint coated material through a film coating material so that a film coating layer can be formed, wherein the thickness of the film coating layer is smaller than a preset threshold value; andoil paint in a first color is sprayed to the film coating layer to form a middle paint layer, wherein the first color is the color of the material, the color paste concentration of the oil paint in the first color is smaller than preset concentration, and therefore the problem of paint falling is not prone to being caused when a non-conducting electroplating technology NCVM is used for showing thedark color effect.
Description
technical field [0001] The embodiments of the present invention relate to the field of coating technology, and in particular to a material surface treatment method and a casing. Background technique [0002] With the development of surface treatment methods for mobile phones, there are more and more metal shells, and the colors are becoming more and more diverse. There are more and more oxidized colors of aluminum alloys, and black matte or dark colors have gradually become popular colors. [0003] However, the inventors have found that at least the following problems exist in the prior art: most of the mobile phone side buttons or camera decorations are made of plastic materials, and the overall color effect is consistent, requiring that the side buttons and camera decorations also need to be anodized The same dark color usually uses the non-conductive plating technology NCVM, but when it is made into a dark color, it is prone to the problem of paint peeling.
