Currently, the industry utilizes the oxidation property of the |g alloy product. The electrochemical treatment of the anode treatment controls the formation of the oxide layer to prevent the progress of the oxidation of the material. In addition, in order to increase the appearance of various colors on the aluminum material to increase the aesthetic effect, a plurality of anode treatments are performed on the material. The outer surface has a colorful effect; however, there are many previous anode treatments, but the following defects still exist: 1. Between each anode treatment, it is necessary to cut the 35 material to process the Need to shape and remove the previous anodizing treatment left: to facilitate the formation of oxide layers of different colors at the cutting point, however, = cutting ^ often need to cooperate with the cutting fluid for use, if the processing is not difficult for the materials (4) When a little anode treatment is carried out, the part of the oil-filled part 2: the lower part is attached to the name material, resulting in poor processing. The ',, and the method effectively treats the oxide layer II, as the industry has anodized, after the first-anodic treatment, 5 201016891, if the protective layer is not formed at the anode treatment, in the process of re-anodicizing the electrode The first anodized oxide layer is applied to a portion of the electrode, causing processing defects.纟 'As the industry has anodized, after the first anodizing, if a protective layer is not formed at the anode treatment, the second oxidized layer will be stacked in the anodicly treated electrode. It is combined with the first anodized oxide layer, causing a collapse of color. For example, in the industry, the anode treatment is formed after the first-anodic treatment, and the ink layer is formed on the oxide layer. However, the oil film layer is subjected to the re-cutting process, which is easy to produce a tearing process at the edge of the slit. 5. If the industry has anodized treatment, after the first anodizing treatment, an ink layer is formed on the oxide layer to protect it, but the oil film layer needs to be removed after being treated again. In view of the above-mentioned defects and deficiencies in the existing anode treatment, improvements have been made. SUMMARY OF THE INVENTION Therefore, the present inventors have developed a kind of energy through continuous research and experiment in view of the lack of existing anode treatment techniques and the difficulty in maintaining the surface treatment of aluminum alloys and maintaining quality. The invention of the existing deficiency is improved. In order to achieve the above object, the present invention provides an anode multicolor surface treatment method for an aluminum alloy, which comprises: (") preparing a substrate: an aluminum alloy substrate to be subjected to coloring processing, through a processing machine Processing of the outline shape of the material, after the shape processing, 6 201016891 Degreasing and degreasing the substrate, thereby cleaning the cutting fluid and the oily oil attached to the outer surface of the substrate. After the degreasing and degreasing, the substrate is washed with water to remove Impurities on the surface; /, (2) Surface treatment: Put the cleaned substrate into the electrolyte and enter the lamp for anode treatment to form an oxide layer on the outer surface of the substrate; ❹ _ (3) Form a film·· Forming on the outer surface of the substrate after the anodization - a film made of transparent acid-resistant insulating plastic, forming a protective layer outside the oxide layer of the substrate, thereby giving the substrate a covering effect; (4) Processing: Forming the substrate on which the film is formed, thereby partially removing the film and the oxide layer covering the outer surface of the substrate, thereby exposing the outer surface of the substrate to the outer layer of the oxide layer and the outside of the thin medium. After partial processing, the substrate is degreased and degreased and cleaned to remove oil collapse and > (5) Surface re-treatment: the cleaned substrate is placed in another electrolyte for anodizing to make the substrate The processed partial outer surface forms another oxide layer' such that the outer surface of the substrate exhibits more than one color effect. Preferably, in the surface treatment process, when the oxide layer is formed on the outer surface of the substrate, the substrate is taken out to the electrolytic solution for drying, so that the oxide layer can be firmly adhered to the outer surface of the substrate. Preferably, in the surface reprocessing process, after the oxide layer is formed on the partial outer surface of the earth material, the substrate is taken out to the electrolyte for drying. Preferably, in the method, a CNC turning/cutting machine is used. Preferably, in the method, sodium hydroxide is used to perform degreasing and degreasing treatment on the surface of the substrate.彩色 The color substrate produced by the above process is formed by forming a thin _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ During the processing, the cutting fluid or other oil stains adhere to the surface of the substrate, thereby causing the oxide layer covering the oil to be detached, so that the oxide layer formed by the anode treatment can be closely attached to the outer surface of the substrate. Forming a stable and wear-resistant structure and repeating the process of processing the surface and re-processing the surface after the film is formed into a film, the color can be accurately displayed on the substrate on which the oxide layer has not fallen off. The visual effect is relatively high for the purpose of improving the anode processing efficiency and quality of the aluminum alloy. [Embodiment] The present invention provides an anode multi-color surface treatment method for an aluminum alloy, which is characterized in that after the first anodized aluminum alloy substrate is formed on the outer surface of the substrate, a related film is processed. And the anode treatment can effectively prevent the cutting fluid or other oil stains from adhering to the surface of the substrate during processing, so that the oxide layer formed by the anode treatment can closely adhere to the outer surface of the substrate, thereby forming a stable and wear-resistant protective structure. And can accurately form a color effect on the outer surface of the substrate, thereby improving the anode processing efficiency and quality of the aluminum alloy.
