Mobile terminal shell, preparation method thereof, and mobile terminal

Abstract

The invention provides a mobile terminal shell, a preparation method thereof, and a mobile terminal. The preparation method comprises following steps: subjecting a metal shell to a first anodic oxidation treatment so as to form a first anodic oxidation membrane on at least part of the surface of the metal shell; adopting a non-shielding technology to form patterns on the first anodic oxidation membrane so as to expose part of the metal shell; and subjecting exposed metal shell to a second anodic oxidation treatment so as to form a second anodic oxidation membrane; wherein the color of the first anodic oxidation membrane is different from the color of the second anodic oxidation membrane. The inventor finds that the method can rapidly and simply prepare a mobile terminal shell with a colorful appearance without any shielding treatment, the operation is simple and convenient, the cost is low, moreover, the precision is high, the method can form different patterns and lines, the appearance requirements of clients can be better satisfied, and the user experience is improved.

Description

technical field [0001] The present invention relates to the technical field of mobile terminals, and in particular, to a mobile terminal casing, a preparation method thereof, and a mobile terminal. Background technique [0002] At present, if the appearance effect of contrasting colors is required for the metal shell, the usual method is to cover it after oxidation, avoid the part that needs to be processed, and then perform deplating, remove the oxide film of the part that needs to be treated, and then re-anodize the color Form a two-color contrast effect. However, the above method has complicated procedures and high cost; firstly, the product needs to be shielded after the anode, and then deplating is performed to remove the oxide film on the unshielded part, and then the secondary anode is performed again; after the secondary anode is completed, the film is stripped to remove the ink Masking layer: The masking requirements are relatively high. It must be ensured that the...

Problems solved by technology

However, the above method has complicated procedures and high cost; firstly, the product needs to be shielded after the anode, and then deplating is performed to remove the oxide film on the unshielded part, and then the secondary anode is performed again; after the secondary anode is completed, the film is stripped to remove the ink Masking layer: The masking requirements are relatively high. It must be ensured that the masking layer has no defects, no holes, no curling, accurate dimensions, clear edges and no bends, etc., but the accuracy is poor in actual operation, and jagged defects will appear on the masking edge, and the masking cost higher

[0003] Therefore, the relevant processes of the metal shells currently prepared still need to be improved.
