Embodiment 1～4

[0025] An aluminum alloy copper salt electrolytic coloring method comprises the steps of:

[0026] (1) Pre-treatment: First, the area is 20cm 2 The aluminum profile is placed in the chemical polishing tank for chemical polishing;

[0027] (2) Anodizing treatment: the pre-treated aluminum profile enters the anodizing tank for electrolytic oxidation treatment. The formula of the anodizing bath is: 97% industrial sulfuric acid: 150-200g / L;

[0028] The temperature of the anodizing process is 18-20°C, and the current density is 1.2-1.5A / dm 2 , the time is 30-50 minutes. ;

[0029] (3) Sensitization treatment: soak the anodized aluminum profile in the sensitization solution as shown in Table 1 for 1-4 minutes, and the sensitization temperature is 18-20°C;

[0030] (4) Coloring treatment: Electrolytic coloring treatment is performed on the sensitized aluminum profile in the coloring solution as shown in Table 1, the coloring voltage is 12-16V, and the coloring temperature is 20-...

Abstract

The invention discloses an electrolytic coloring method of aluminum alloy copper salt and a product. The electrolytic coloring method comprises a pretreatment working procedure, an anodic oxidation treatment working procedure, a sensitizing treatment working procedure, a coloring treatment working procedure, a hole semi-sealing treatment working procedure and an electrophoresis treatment working procedure, wherein in the sensitizing treatment working procedure, a sensitizing solution contains a reducing agent and a complexing agent. A section material after sensitizing treatment is higher in combining capacity with electrolytic coloring solutions, and the color of the section material after being colored is stable.

Description

technical field [0001] The invention relates to the field of aluminum alloy surface treatment, in particular to an aluminum alloy copper salt electrolytic coloring method and product. Background technique [0002] By electrolytically depositing metal copper in the oxide film of aluminum profiles, a red aluminum alloy surface can be obtained, which can be widely used in the interior decoration of various high-end buildings to meet the needs of middle and high-end consumers. However, the coloring of electrolytic copper is due to its special The production process is prone to discoloration during the production process, which in turn leads to low production yield and poor weather resistance. Contents of the invention [0003] The invention aims to provide an aluminum alloy copper salt electrolytic coloring method and product, which solves the problem in the prior art that aluminum profiles are easy to fade during the production process of electrolytic red coloring. [0004] ...
