Abstract
The invention relates to the technical field of aluminum material processing, in particular to an aluminum material surface treatment process. Acetone is used for cleaning the surface of an aluminum material; then, clear water is used for cleaning the surface of the aluminum material until residues on the surface of the aluminum material are totally removed; the aluminum material is put in NaOH solution of 80 g/L for alkali corrosion, and is washed by the clear water after being taken out; the aluminum material is put in cleaning liquid for dipping; the cleaning liquid is prepared by 25 parts of aromatic hydroxy acid, 15 parts of N, N-dimethylformamide, 5 parts of dilute nitric acid, 0.5 part of rhamnoside, 10 parts of glycerin and 40 parts of water; the aluminum material is washed by water after being fished out until the pH value of the washing water becomes neutral; and the aluminum material is dried. The surface treatment process is simple in operation process, adds a cleaning liquid dipping step, reasonably designs a formula and a preparation method of the cleaning liquid, and realizes formation of one layer of effective protection film on the surface of the aluminum material; the protection film is longer in service life and higher in corrosion resistance; and the surface performance of the aluminum material is greatly improved.
Description
Technical field
The present invention relates to aluminum profile extrusion technical field, specifically relate to a kind of process of surface treatment of aluminium.
Background technology
Aluminium is used widely because it has good corrosion resistance nature, and aluminium needs when machine-shaping to carry out surface treatment to it, to form protective membrane.
Summary of the invention
For the technical problem existed in prior art, the object of the present invention is to provide a kind of process of surface treatment of aluminium, for achieving the above object, present invention employs following technical scheme:
A process of surface treatment for aluminium, step is as follows:
Step 1., use acetone aluminium material surface is cleaned, then with clear water rinse, until aluminium material surface residue cleans up;
Step 2., aluminium is put into the NaOH solution alkaline etching 5 minutes of 80g/L, rinse with clear water after taking-up;
Step 3., aluminium put into the scavenging solution being heated to 50 DEG C in advance and soaks 10 minutes, scavenging solution is made up of 25 parts of aromatic hydroxyl acid, 15 parts of DMFs, 5 parts of dust technology, 0.5 part of rhamnoside, 10 parts of glycerol and 40 parts of water;
Step 4., pull rear water out and rinse until the pH value of wash-down water returns to neutrality, dry at 150 DEG C.
Preferably, the preparation method of the scavenging solution that 3. described step uses is: in container, first add 25 parts of aromatic hydroxyl acid and 15 parts of water, stir 5 minutes; Then slowly add 5 parts of dust technology, limit edged stirs, and stirs 5 minutes after interpolation; Then slowly add 15 parts of DMFs and 15 parts of water, limit edged stirs, and stirs 5 minutes after interpolation; Then slowly add 0.5 part of rhamnoside, limit edged stirs, and stirs 5 minutes after interpolation; Finally add 10 parts of glycerol and 10 parts of water fast, stir 5 minutes.
Beneficial effect of the present invention shows:
1), the scavenging solution that uses in process of surface treatment, its formulating of recipe is reasonable, novel, particularly with the addition of a small amount of rhamnoside, can significantly improve the processing efficiency of scavenging solution, then improves the surface treatment properties of aluminium.
2), the preparation method of scavenging solution, by progressively adding and different order of addition(of ingredients), the solubility property between each material can not only be improved, the possibility of particle agglomeration can also be avoided, thus surface processing efficiency is promoted significantly.
3), process of surface treatment, operating procedure is succinct, set up scavenging solution soaking step, the formula of appropriate design scavenging solution and the preparation method of scavenging solution, thus realize forming one deck effective " protective film " at aluminium material surface, and the work-ing life of this protective film is longer, corrosion resistance nature is high, significantly improves the surface property of aluminium.
