Abstract

The invention provides an anodic oxidation preparation method for antibacterial colorful aluminum or aluminum alloys, and in particular, relates to the technical field of surface treatment. The methodcomprises the following steps: (S1) the pretreatment is performed on aluminum or aluminum alloys; (S2) electrolyte is prepared; (S3) the two aluminum or aluminum alloy materials obtained in the step(S1) are taken to dip in the electrolyte obtained in the step (S2); and the temperature of the electrolyte is controlled within 15-25 DEG C; (S4) alternating direct current of 10-20 V is applied between the two aluminum or aluminum alloys; and the electrification time is 5-20 minutes; (S5) alternating current of 5-15 V is applied between the two aluminum or aluminum alloys treated in the step (S4); and the electrification time is 3-15 minutes; (S6) the hole sealing treatment is performed on the aluminum or aluminum alloy materials obtained in the step (S5); and (S7) two colorful aluminum or aluminum alloys with an antibacterial function are synchronously obtained by cleaning and drying. The method can prepare the colorful aluminum or aluminum alloys with the antibacterial function on the surfaces, meanwhile, can reduce operation procedures in the aluminum or aluminum alloy oxidation and coloring processes, and improves the production efficiency.

Description

technical field

[0001] The invention belongs to the technical field of surface treatment, and in particular relates to an anodic oxidation preparation method of antibacterial and colored aluminum or aluminum alloy. Background technique

[0002] Aluminum and aluminum alloys have many advantages such as high specific strength, good electrical and thermal conductivity, good corrosion resistance, and easy surface treatment. They are widely used in aviation, automobiles, building materials, electronics, industrial equipment and other fields. Metal materials for steel. At present, anodic oxidation and electrolytic coloring of aluminum or aluminum alloy materials is a very mature preparation method. The most widely used anodic oxidation coloring method in industry is to use sulfuric acid as the electrolyte oxidation, and then use inorganic or organic solution as the coloring liquid.

[0003] However, during the process of anodic oxidation and coloring in the above-mentioned proces...
