Description of the Invention: [Technical Field] The present invention relates to an anode surface treatment method for an aluminum alloy, and more particularly to a method for performing multicolor treatment on the surface of a smelting alloy, which is generally affiliated with the % pole treatment. Application 'The mouth of the technical field of application of aluminum alloy products. [Prior Art] The '% pole treatment is a method in C〇nversi〇n Coating, which mainly uses a chemical or electrochemical treatment to form a coating layer containing the metal component on the surface of the metal. For example, zinc chromate treatment, zinc phosphate treatment of steel and anode treatment of aluminum alloy, etc., the current industry uses the characteristics of aluminum alloy products to easily oxidize, through the electrochemical treatment of anode treatment to control the formation of oxide layer, In order to prevent further oxidation of the aluminum material, in addition, in order to increase the appearance of various colors on the aluminum material to enhance the aesthetic effect, the anode material is subjected to multiple anode treatments to form a colorful effect on the outer surface; however, there are currently The multiple anode treatments still have the following defects: 1. Between each anode treatment, the aluminum material needs to be processed by cutting, etc., in order to process the desired shape and remove the remaining alum treatment. The layer 'is easy to form oxide layers of different colors at the cutting point. However, when cutting, it is often necessary to use the cutting fluid for use. After the processing, the aluminum material is not cleaned, and some oil stains are attached to the outer surface of the aluminum material. When the next anode treatment, t is covered in the oil collapsed portion, that is, the oxide layer cannot be effectively attached to the ig material to cause the processing effect. Not good. Second, as the industry has anodized, after the first anodizing, 5 1338056, if a protective layer is not formed at the anode treatment, then the first anodized oxidation will be carried out during the re-anodized electrode process. The layer gives the partial electrode down' causing processing to go crazy. Second, if the industry has anodized treatment, after the first anodizing treatment, the right does not form a protective layer at the anode treatment, in the process of re-anodizing the electrode, the second oxide layer will be superposed. On the first anodized oxide layer, a collapsed color is created. 4. If the industry has an anodizing treatment, after the first anodizing treatment, an ink layer is formed on the oxide layer to protect it, but the oil film layer is processed in the re-cutting process, which is easy to tear 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 finally developed a kind of energy through continuous research and experiment in view of the lack of existing anodizing 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 multi-color surface treatment method for the alloy, which includes: (1) preparing a substrate: an aluminum alloy substrate processed by a person who is processed into a color A processing machine performs the processing of the outline of the substrate profile, and after the shape processing, 6 1338056 degreased and degreased. The color substrate produced by the above process is transparent to the substrate oxide layer (4) to form a film made of transparent acid-resistant insulating plastic, so that the substrate is effectively prevented from being processed during subsequent processing and anodizing. The other oil line on the cutting line adheres to the surface of the substrate, thereby causing the phenomenon that the emulsion layer covering the oil collapse is detached, so that the oxide layer formed by the anode treatment can closely adhere to the outer surface of the substrate, thereby forming a stable surface. And the wear-resistant structure of the structure 4, and the process of repeating the processing and the surface re-treatment after forming the film on the substrate can accurately display the colorful visual effect on the substrate on which the oxide layer has not fallen off, and relatively improve The purpose of aluminum alloy anode processing efficiency and quality. [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 protection. The structure 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. The invention relates to an anode multi-color surface treatment method for an aluminum alloy, in order to understand the technical features and practical effects of the creation in detail, and can be implemented according to the contents of the specification, and further illustrated by a diagram (as shown in the first figure). A preferred embodiment, as described in detail below: 8 1338056 Accurately forms more than one color on the outer surface of the substrate.
