Abstract
The invention relates to a secondary double-color oxidizing process for an aluminum alloy. The secondary double-color oxidizing process comprises the following process steps: firstly, performing primary oxidizing and coloring on the aluminum alloy, and performing primary hole sealing; then, treating a to-secondarily-oxidized to-be-colored surface to remove an oxide film on the to-be-colored surface; removing grease, performing secondary oxidizing and coloring; and finally, performing secondary hole sealing to obtain a finished product, wherein in the primary oxidizing and coloring step, anti-acid dyes are adopted, and the thickness of the oxide film on the to-be-primarily-oxidized to-be-colored surface is controlled to be 15 [mu]m to 20 [mu]m; and in the primary hole sealing step, a neutral hole sealing agent is adopted, hole sealing time is controlled to be 10-30 minutes, and a hole sealing temperature is controlled to be 70 DEG C to 90 DEG C. The secondary double-color oxidizing process overcomes the defects such as complexity, too many processes, long needed time and low efficiency of an existing process, and realizes convenient and simple operations, short needed time and high efficiency.
Description
【Technical field】
The present invention relates to the technical field that aluminum alloy surface is processed, and in particular to a kind of secondary double-colored oxidation work of aluminium alloy
Skill.
【Background technology】
Aluminium alloy extrusions is because its is light, low price the features such as, be widely used in Aeronautics and Astronautics, automobile, machine-building, ship
The fields such as oceangoing ship.With the continuous extension of range of application, the surface coloring to aluminium alloy extrusions is required also to improve constantly, much will
The different surfaces in aluminium alloy extrusions are asked to carry out double-colored process.Currently used secondary double-colored oxidation technology is：Carry out first
Once oxidation is coloured, and is then blocked using ink, 160 DEG C of high-temperature baking half an hour is then carried out to dry ink, by oil
Ink can just carry out secondary oxidation coloring after blocking to the coloring of once oxidation, with prevent secondary oxidation to once oxidation
Color produces impact.And during secondary oxidation, ink easily comes off, after the completion of secondary oxidation, finished product is also needed to again
Ink process is clean, and processing procedure is cumbersome.It can be seen that, not only technique is loaded down with trivial details for above-mentioned technique, operation excessive, operation
Overlong time, affects efficiency, and also result in the increase of production cost.
【The content of the invention】
To solve the above problems, it is an object of the invention to provide one kind need not be hidden after once oxidation using ink
The secondary double-colored oxidation technology of aluminium alloy of gear.
For achieving the above object, the technical scheme taken of the present invention is：The secondary double-colored oxidation technology of aluminium alloy, including it is as follows
Processing step：First once oxidation coloring is carried out to aluminium alloy, carry out a sealing of hole, then need to colour face to secondary oxidation is carried out
Process to remove the oxide-film on the coloring face, then then degreasing carries out secondary oxidation coloring, finally carries out secondary hole sealing
Process obtains finished product；Wherein in once oxidation tinting steps, using acid-resisting dyestuff, and control once oxidation and need to colour face
On oxide thickness in 15～20um；In a sealing of hole step, using neutral hole sealing agent, sealing of hole time control is 10～30
Minute, sealing of hole temperature control is at 70～90 DEG C.
Compared with prior art, the present invention has the advantages that：The secondary double-colored oxidation technology of above-mentioned aluminium alloy, its
Using unique once oxidation coloring process, the coloring acid-resisting for making once oxidation is largely increased, and is carrying out secondary oxidation
When, blocked without the need for reusing ink, so as to overcome, the loaded down with trivial details of existing process, operation are excessive, required time is long, efficiency is low
Etc. defect, realize that easy to operate simple, required time is short, efficiency high.
