Problems solved by technology
Since anodic oxidation requires the use of acid and alkali, each time anodic oxidation is performed, it is easy to damage the oxide film formed in the previous anodic oxidation, resulting in the failure of the performance test and the difficulty of color difference management. At the same time, the cost of multiple anodic oxidation is high and the finished product is good These problems make it difficult to apply 4-color anodizing in actual production

Embodiment Construction
[0008] Below in conjunction with accompanying drawing, invention is described in further detail.
[0009] Such as Figure 1-2 As shown, a four-color oxidation process, the specific steps are as follows: (1) at a voltage of 14 volts, a time of 40 minutes, and a drying temperature of 40-60 degrees Celsius, the first anodic oxidation is not sealed; (2) By printing shielding ink to the icon parts that do not need to be dyed black; (3) at a temperature of 55 degrees Celsius, take off the printed layer after dyeing black; (4) After that, at a temperature of 55 degrees Celsius, carry out Dye gold sealing treatment; the conditions for the above sealing treatment are 90 degrees Celsius and 30 minutes; (5) remove a part of the sealed oxide film by physical highlighting method, and expose the metal under the oxide film; (6) aim at removing the oxide film The place is dyed red or blue by the second anodic oxidation sealing treatment; the treatment voltage of the above-mentioned second an...

The invention discloses a four-color oxidation process. The four-color oxidation process specifically comprises the following steps that (1) primary anodic oxidation is carried out, and sealing is notcarried out; (2) ink is shielded to icon portions not needing to be dyed with black in a printing mode; (3) a printing layer is stripped off after dyeing with black; (4) then the former spray covering position is subjected to gold dyeing and hole sealing under the temperature condition of 55 DEG C; (5) part of a sealed oxide film is removed in a physical highlight manner, and metal below the oxide film is exposed; (6) the position without the oxide film is subjected to secondary anodic oxidation for red or blue dyeing and hole sealing treatment; (7) the other part of the sealed oxide film isremoved in a physical highlight manner, and metal below the oxide film is exposed; and (8) finally, the position without the oxide film is subjected to tertiary anodic oxidation for purple dyeing andhole sealing treatment. The four-color oxidation process has the effects of metal product coloring diversity and technological adaptability.
Description
technical field [0001] The invention relates to the field of oxidation technology, in particular to a four-color oxidation technology of aluminum alloy. Background technique [0002] At present, the anodic oxidation coloring of aluminum alloy products is subject to process conditions, generally one or two color treatments, and most of the coloring is relatively single. Moreover, the method of multi-color anodization is generally as many times as there are colors, for example, four colors require 4 times of anodization for dyeing. Since anodic oxidation requires the use of acid and alkali, each time anodic oxidation is performed, it is easy to damage the oxide film formed in the previous anodic oxidation, resulting in the failure of the performance test and the difficulty of color difference management. At the same time, the cost of multiple anodic oxidation is high and the finished product is good These problems make it difficult to apply 4-color anodizing in actual product...
