Problems solved by technology

Electrolytic yellowing is a topic that has been studied more in recent years, but the problems of light color and poor stability have not been well resolved. The application publication number is CN 109183120A (application number is 201811157387.6). The Chinese invention patent application discloses an aluminum The production process of titanium gold electrolytic coloring of profile anodized film includes the following treatment steps: degreasing, water washing, water washing, alkali etching, anodizing, water washing, water washing, activation treatment, electrolytic coloring, water washing, water washing, sealing and water washing treatment processes, The process of the technical scheme is complicated, the electrolytic coloring solution has no complexing agent, no inhibitor and precipitation agent, and the electrolytic coloring solution is unstable
[0003] After the aluminum alloy is oxidized, an oxide film of a certain thickness is formed on the surface. Due to the large number of micropores on the surface of the oxide film, it must be properly sealed. Common sealing methods include boiling water or high-temperature steam sealing technology, calcium magnesium salt sealing technology, Nickel salt sealing, fluoride sealing, polymer resin sealing; conventional sealing products have unstable surface color, matting, poor anti-fingerprint and oil resistance, and the ability to inhibit "powder frost" is not strong

Abstract

The invention discloses an electrolytic coloring treatment method for the titanium golden color surface of an aluminum material. The method comprises de-oiling, sand blasting, acid pickling, water washing, flushing, sprinkling and anodic oxidation, wherein a sprinkled aluminum alloy product is suspended on a suspending rack, the suspending rack is placed in an anodic oxidation solution, and anodicoxidation treatment is carried out under direct current electricity; water washing, flushing, sprinkling and secondary oxidation are sequentially carried out; the aluminum alloy product is placed ina coloring solution to expand holes, and then, secondary anodic oxidation is carried out under alternate current electricity; water washing is carried out after alternate current electrolytic coloring; the aluminum alloy product is put in hole sealing working fluid to seal the holes; and after water washing and drying are carried out on the aluminum alloy product, the aluminum alloy product with the titanium golden color surface is obtained. By improving the electrolytic coloring technology and agent, the coloring effect is more uniform and stable, and the coloring effect is optimal.

Description

technical field [0001] The invention relates to the technical field of aluminum electrolytic coloring titanium gold, in particular to a surface treatment method for aluminum electrolytic coloring titanium gold. Background technique [0002] Aluminum is one of the six most widely distributed metals in nature, accounting for 7.56% of the total weight of the earth's crust. Aluminum and its alloys are known for their light weight, high plasticity, good electrical conductivity, thermal conductivity, good corrosion resistance, and non-toxic oxidation and corrosion products. . Higher requirements are put forward for aluminum surfaces with various colors. Most of the electrolytic coloring processes currently used in my country are nickel salts, tin salts or nickel-tin mixed salts, and the colors are mostly bronze. Therefore, it is of great significance and urgency to study the multi-color electrolytic coloring process of aluminum alloy and improve its decorative property to promote...
