Problems solved by technology

[0004] The purpose of the present invention is to provide a nano-ink for realizing aluminum alloy multi-color anode, which solves the problem that the process is complex and has no mass production. The prior art requires the process of two-color anode to use strong alkali to deoxidize the film, which is easy to cause size deviation. The process flow Long, complex, pollutes the environment, needs to spray masking ink, the existing ink needs to be acid and alkali resistant, spraying pollutes the environment, subsequent masking ink needs to use strong solvents, and pollutes the technical problem of the environment

Abstract

The invention discloses nano ink for realizing a multicolor anode of an aluminum alloy, which is prepared from the following raw materials in percentage by weight: 70-80% of modified acrylic resin, 16-24% of superfine nano pigment, 1-2% of non-silicon defoaming agent, 1-2% of flatting agent and 1-2% of special curing agent. Degreasing of aluminum alloy is performed using organic acid, after degreasing, polishing operation on an aluminum alloy is achieved through the aluminum chemical polishing agent, after polishing, a power source is connected, anodic oxidation on the aluminum alloy can be achieved, after oxidation, oxidation film holes are formed in the surface of the aluminum alloy, dyeing is conducted, dye permeates into the film holes through the siphon benefit and the positive and negative charge adsorption principle, coloring on the aluminum alloy is achieved, and in the coating process, strong base deoxidation is not needed, the size after coating is accurate, the technological process is short and simple, the environment is better protected, the printing ink does not need acid and alkali resisting treatment, the spraying environment is cleaner, a strong solvent is not needed, and the environment is better protected.

Description

technical field [0001] The invention relates to the field of ink processing, in particular to a nano-ink for realizing aluminum alloy multi-color anodes. Background technique [0002] Ink is an important material for printing packaging materials. It expresses patterns and characters on the substrate through printing. The ink includes main components and auxiliary components. They are evenly mixed and rolled repeatedly to form a viscous colloidal fluid; [0003] Generally, aluminum alloys are dyed to achieve different single colors or gradient colors. To achieve multi-color anodes on the surface of aluminum alloys, the process is complicated and has no mass production. The existing technology requires two-color anodes to use strong alkali to deoxidize the film. , It is easy to cause size deviation, the process is long, complex, and pollutes the environment. It is necessary to spray masking ink. The existing ink needs to be acid-resistant and alkali-resistant. Contents of th...
