Abstract

The invention discloses an aluminum profile anode oxide film titanium gold electrolytic coloring production process comprising the following processing steps of degreasing, water washing, water washing, alkali corrosion, anodic oxidation, water washing, water washing, activating treatment, electrolytic coloring, water washing, water washing, hole sealing and water washing. An electrolytic coloringagent in the electrolytic coloring step comprises, by weight, 10%-20% of selenium dioxide, 2%-8% of magnesium sulfate, 3%-7% of sulfuric acid, and the balance water. Trough solution in an electrolytic coloring trough comprises 40-50g / L of electrolytic colorant, 20-25g / L of free sulfuric acid, and the balance water. In the electrolytic coloring processing step, the trough solution in the electrolytic coloring trough is 40-50 DEG C, the voltage is 15-17 v, and coloring time is 0.5-8 min. A titanium gold aluminum profile prepared with the production process provided by the invention is bright incolor, a coloring film is uniform and stable in color and good in quality, no color fading problem exists in the use process, high weather resistance is achieved, and mass production can be formed.

Description

technical field [0001] The invention relates to the technical field of surface treatment and decoration of aluminum and aluminum alloy products, in particular to a production process of titanium gold electrolytic coloring of anodic oxidation film of aluminum profiles. Background technique [0002] As we all know, the titanium gold color of aluminum profiles is golden yellow, elegant, beautiful and pleasing to the eye, and is widely used for interior decoration. However, the fly in the ointment is that it always has the problem of fading during production or use, especially electrophoretic titanium gold. The reason for discoloration may be that the colored precipitates in the pores of the oxide film are discolored due to changes in the material structure when they are heated or irradiated by ultraviolet rays in sunlight. It is for this reason that the use and promotion of titanium-gold aluminum profiles are greatly restricted, especially electrophoresis titanium-gold aluminu...
