Embodiment 1

[0045] Embodiment 1: a kind of anodized aluminum plate, its preparation process comprises the following steps:

[0046] A. Sheet metal processing: select 1mm thick aluminum or aluminum alloy panels for sheet metal processing, so as to achieve the workpiece with the dimensional accuracy and shape accuracy specified in the design;

[0047] B. Hanging: Clamp the workpiece with an elastic fixture to ensure current flow, because an oxide film will be formed quickly on the surface of the fixture and the workpiece during anodic oxidation, and the contact point will be changed if the fixture and workpiece are slightly loose during the process position, which hinders the flow of current, so the workpiece must be clamped with an elastic clamp to avoid burning the workpiece due to heat generated by poor contact;

[0048] C. Anodizing:

[0049] C1, chemical degreasing: the workpiece obtained in step A is alkaline-washed for 1 minute at 50° C. with an alkaline lotion to remove organic gre...

Embodiment 2

[0072] Embodiment 2: a kind of anodized aluminum plate, its preparation process comprises the following steps:

[0073] A. Sheet metal processing: Select a 4mm thick aluminum or aluminum alloy panel for sheet metal processing, so as to achieve the workpiece with the dimensional accuracy and shape accuracy specified in the design;

[0074] B. Hanging: Clamp the workpiece with an elastic fixture to ensure current flow, because an oxide film will be formed quickly on the surface of the fixture and the workpiece during anodic oxidation, and the contact point will be changed if the fixture and workpiece are slightly loose during the process position, which hinders the flow of current, so the workpiece must be clamped with an elastic clamp to avoid burning the workpiece due to heat generated by poor contact;

[0075] C. Anodizing:

[0076] C1, chemical degreasing: the workpiece obtained in step A is alkaline-washed at 65° C. for 5 minutes with alkaline washing solution to remove or...

Embodiment 3

[0099] Embodiment 3: a kind of anodized aluminum plate, its preparation process comprises the following steps:

[0100] A. Sheet metal processing: Select a 6mm thick aluminum or aluminum alloy panel for sheet metal processing, so as to achieve the workpiece with the dimensional accuracy and shape accuracy specified in the design;

[0101] B. Hanging: Clamp the workpiece with an elastic fixture to ensure current flow, because an oxide film will be formed quickly on the surface of the fixture and the workpiece during anodic oxidation, and the contact point will be changed if the fixture and workpiece are slightly loose during the process position, which hinders the flow of current, so the workpiece must be clamped with an elastic clamp to avoid burning the workpiece due to heat generated by poor contact;

[0102] C. Anodizing:

[0103] C1, chemical degreasing: the workpiece obtained in step A is washed with alkaline washing solution for 10 minutes at 80°C to remove organic grea...

Abstract

The invention relates to the technical field of building materials, in particular to an anodized aluminum plate and a preparation process thereof. The invention relates to an anodized aluminum plate, which includes an aluminum alloy panel, and an oxide film layer is provided on the outer surface of the aluminum alloy panel. The oxide film layer is uniform and dense, and its thickness is 10-15um, which can significantly improve the wear resistance and corrosion resistance of aluminum alloy workpieces. In addition, the surface of the oxide film layer is porous, and various dyes are formed after adsorbing dyes in these pores. The appearance of the color meets people's requirements for the diversity of appearance colors; the manufacturing process of the anodized aluminum plate of the present invention is reliable and easy to implement, so that the final product anodized aluminum plate has adhesion, acid resistance, solvent resistance, wear resistance, Good impact resistance and mechanical properties.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to an anodized aluminum plate and a preparation process thereof. Background technique [0002] Most of the traditional building decoration materials are stone or gypsum board, but these decoration materials are relatively heavy, the building safety is poor, and the installation and processing performance is also poor. Aluminum plate is widely used in the field of architectural decoration due to its excellent processing performance, light weight and low price. [0003] However, after the existing aluminum plate is used in the natural environment for a period of time, the oxidation of the aluminum plate itself will make the surface luster dull, and it is easy to be corroded, which affects the appearance and quality; at the same time, due to the single color of the aluminum material, it cannot meet the requirements of the recent years. People's demand for various colors of ...
