Embodiment Construction

[0024] Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary only for explaining the present invention and should not be construed as limiting the present invention.

[0025] In one aspect of the invention, the invention provides a method for preparing a board. In the plate prepared by the method, the metal primer layer formed on the surface of the epoxy resin layer can improve the metal texture of the epoxy resin layer, and the middle paint layer formed on the surface of the metal primer layer far away from the epoxy resin layer can improve the environmental protection. The brightness of the epoxy resin, the metal primer layer and the middle paint layer can also improve the surface smoothness and appe...

Abstract

The invention discloses a board, a manufacturing method thereof, a shell and a mobile terminal. According to the embodiment of the invention, the method comprises the steps that a metal base materialis provided, and an epoxy resin layer is arranged on the partial surface of the metal base material; a metal priming paint layer is formed on the side, away from the metal base material, of the epoxyresin layer; and a middle paint layer is formed in the side, away from the epoxy resin layer, of the metal priming paint layer. Accordingly, for the board prepared through the method, the metal priming paint layer and the middle paint layer can improve the metal texture and the hue brightness degree of the epoxy resin layer, the surface evenness and appearance delicacy are improved, the matching consistence of the epoxy resin layer and the metal base material is improved remarkably, and the appearance effect is improved. Meanwhile, the method can effectively avoid the problems of orange peel and oil accumulation balance.

Description

technical field [0001] The invention relates to the field of electronic equipment, in particular, to a board and a preparation method thereof, a casing, and a mobile terminal. Background technique [0002] With the continuous development of the communication electronics industry, the appearance and function of the display screen of the mobile terminal are also constantly changing. At present, the mobile terminal industry is constantly pursuing the design of ultra-high screen-to-body ratio, that is, the design concept of "full screen". As the name suggests, the "full screen" mobile terminal is all screens on the front, and its four borders are designed with no borders, pursuing a screen-to-body ratio close to 100%. However, due to the limitation of the current technology, the "full screen" announced in the mobile terminal industry can only achieve an ultra-high screen-to-body ratio, for example, it can reach more than 80%, and it has an ultra-narrow bezel design, which still...
