Abstract

The invention provides a metal surface treatment method. The metal surface treatment method mainly comprises the steps of anode oxidation treatment, gradient spraying treatment, coloring treatment, printing ink removal treatment and hole sealing treatment. Through gradient spraying, water-soluble printing ink containing dye is sprayed to the surface of an anode oxidation film layer; by controlling the thickness (namely quantity) of printing ink on the surface of a workpiece, a single-color gradient effect is achieved, or a multi-color gradient effect is achieved for the surface of the workpiece through multi-color spraying; various gradient effects such as a linear gradient effect, a radial gradient effect and a rhombic gradient effect can be achieved; a metal surface decoration effect is greatly improved.

Description

technical field [0001] The invention relates to the field of surface treatment, in particular to a metal surface treatment method. Background technique [0002] At present, in metal surface decoration, the realization of gradient color is mainly realized by direct spraying or printing on the surface of the metal workpiece. For the gradation of high-end digital shell decoration, spraying is the most common method. Through the control of spraying equipment, one or several color gradations can be obtained. It can realize the gradual change of various colors, and there are many forms of gradual change, but the existing sprayed surface decoration layer is a paint film, and due to the poor bonding force between the paint film and the metal, it is easy to fall off during use; at the same time, due to the paint film The low hardness is easy to scratch and wear during use, and its surface is easy to lose luster. The influence of these factors limits its application in the surface d...
