Embodiment 1
[0050] The preparation method of the anodized film described in this embodiment is as follows: first, the aluminum plate is cleaned and descaled, and then anodized in an aqueous citric acid solution containing: 20 g / L citric acid, 3 g / L L of 6-amino acid acetic acid, 1.0g / L of hydrogen peroxide, 3g / L of triammonium citrate; when the liquid temperature is 10°C, the current density is 1A / dm 2 , Electrolytic treatment for 20 minutes. The obtained dense anodized aluminum film has an insulating durability time greater than 1000 hours.
Embodiment 2
[0052] The preparation method of the anodized film described in this embodiment is as follows: first, the aluminum plate is cleaned and descaled, and then anodized in an aqueous citric acid solution containing: 30 g / L of citric acid, 4 g / L L of 6-aminoacetic acid, 1.0g / L of hydrogen peroxide, 5g / L of triammonium citrate; when the liquid temperature is 20°C, the current density is 1A / dm 2 , Electrolytic treatment for 20 minutes. The obtained dense anodized aluminum film has an insulating durability time greater than 1000 hours.
Embodiment 3
[0054] The preparation method of the anodized film described in this embodiment is as follows: first, the aluminum plate is cleaned and descaled, and then anodized in an aqueous citric acid solution containing: 35g / L citric acid, 5g / L L of 6-aminoacetic acid, 1.0g / L of hydrogen peroxide, 5g / L of triammonium citrate; when the liquid temperature is 10°C, the current density is 1A / dm 2 , Electrolytic treatment for 30 minutes. The obtained dense anodized aluminum film has an insulating durability time greater than 1500 hours.
