Description

Electrolytic bath solution for coloring aluminum alloy

Technical Field

The invention discloses an electrolytic bath solution for coloring aluminum alloy.

Background

In the prior art, most of aluminum alloy coloring methods are carried out by utilizing section bar anodic oxidation, the main process flow is degreasing, alkaline etching, neutralization, anodic oxidation, coloring, hole sealing, air drying and warehousing, the defect is single color tone, and in the prior art of the electrolytic coloring of the golden yellow aluminum alloy selenium salt with Chinese patent application No. 96119433.3, a hole expanding treatment process is added in the anodic oxidation and electrolytic coloring process.

Disclosure of Invention

Aiming at the problems in the prior art, the invention provides the electrolytic bath solution for coloring the aluminum alloy, the electrolytic bath solution has the effect of quickly and deeply coloring the aluminum alloy section, the coloring color can be from light to deep according to different temperatures, the obtained aluminum alloy section is magnificent titanium yellow, the color is pure, other variegated colors are not contained, and the stability is good.

In order to achieve the purpose, the invention is realized by the following technical scheme: an electrolytic bath solution for coloring aluminum alloy comprises the following raw materials in percentage by weight: 0.5-6% of selenate, 10-35% of sulfuric acid, 1-10% of conductive medium, 0-3% of silane coupling agent, 0-2.5% of explosion-proof agent, 5-20% of hydrogen inhibitor, 10-20% of amino acid and 30-60% of catalyst.

Has the advantages that: the product prepared by the method has the effect that the aluminum alloy section is quickly and deeply colored by the electrolytic bath solution, the colored color can be from light to dark according to different temperatures, the obtained aluminum alloy section is magnificent titanium yellow, the color is pure, other variegated colors are not contained, and the stability is good.
