Description
Technical field
The present invention relates to a kind of processing method of aluminium base, the specifically processing method of oil rub resistance Integral ceiling aluminium base.
Background technology
House is in fitment process, and furred ceiling is an indispensable link；Particularly in kitchen and bath space, due to kitchen
The influence of the moisture and peculiar smell of oil smoke and toilet, this is always the difficult point and emphasis of finishing.The aluminium sheet that usual furred ceiling is used
Surface, which directly makes, baking vanish, but due to surface of aluminum plate poor adhesive force, the adhesive of excessive addition is needed during paint, has been added
The volatile ingredient of poison, so environmental-protecting performance is poor.Ye You enterprises are directly used for furred ceiling using alumina plate；But alumina plate
Oil stain self-cleaning ability it is not high, steam greasy dirt will directly permeate aluminum oxide furred ceiling, cause cleaning difficult.
The content of the invention
The purpose of the present invention is overcome the shortcomings of there is provided a kind of processing method of furred ceiling aluminium base in above-mentioned background technology,
The furred ceiling aluminium base processed with the method should have good resistance to oily stain energy, and manufacturing procedure is simple, cost is relatively low.
The technical scheme that the present invention is provided is：The processing method of oil rub resistance Integral ceiling aluminium base, according to following steps according to
It is secondary to carry out：
1) oil removing
40~60 DEG C of the oil solution that removes soaks 1~2 minute, then washes；Except the oil removing agent content in oil solution be 10~
20g/L, remaining is water；
Or soaked 0.5~1 minute in 50~60 DEG C of mixed solution, then wash；Contain 200g/ in mixed solution
L sulfuric acid and 1g/L dodecyl sodium sulfates, remaining is water；
2) alkaline etching
Soak 2~3 minutes, then wash in 40~50 DEG C of alkaline etching etching solution；NaOH content in alkaline etching etching solution is
50~100g/L, remaining is water；
3) neutralize
Soak 1~2 minute, then wash in neutralization solution at room temperature；Neutralize the ash disposal agent content in solution for 100~
200ml/L, remaining is water；
4) anodic oxidation
3~8 clocks are soaked in 23~28 DEG C of anodizing solution, are then washed；Sulfuric acid content in anodizing solution is 140
~160g/L, oxalic acid content are that 20~50g/L, conductive salt content are 5~10g/L, and remaining is water；
5) sealing of hole
Soaked 1~2 minute in 78~82 DEG C of hole sealing solution；Hole sealing agent FZ7301 contents in hole sealing solution for 5~
10ml/L, remaining is water；
6) post-process
Sprayed 1~2 minute in 58~62 DEG C of hot pure water, you can.
Step 4) in anodizing solution, can also add aluminium ion (Al3+), content is 3~10g/L.
Step 4) in oxidation voltage control between 18~30V.
The conducting salt is the one or more in sodium sulphate, sodium carbonate, potassium sulfate, magnesium sulfate.
The beneficial effects of the invention are as follows：
1st, due to adding oxalic acid in formula, dissolubility of the sulfuric acid to oxide-film surface porous layer, and reduction are reduced
The porosity of oxide-film porous layer so that the low resistant and corrosion resistance of aluminium base significantly improve.
2nd, the voltage of oxidation is improved, and then improves the thickness on the barrier layer under oxidation film layer, and can be with the short time
Interior formation requires thickness oxidation film.
3rd, oxidation trough temperature is improved, adding conducting salt can prevent aluminium sheet from entering the transient voltage of oxidation trough in traveling
It is excessive, aluminium coiled material of burning.
4th, the concentration of hole sealing agent is reduced, it is therefore prevented that cause what typography was handled because hole sealing agent remains in aluminium base plate surface
The defect that adhesive force declines；And spray hot water injection is added in post processing, it can reduce as far as possible because hole sealing agent residual is made
Into oil resistant sump oil lacquer print brush it is bad.
The furred ceiling aluminium base that present invention processing is obtained, can not only be free of the oil resistant baking vanish high intensity knot of adhesive with environmental protection
Close, strong with contamination resistance, cohesive force is good, the characteristics of uniform color is fine and smooth, metal-like is strong, and aluminum oxide can also be strengthened
The durability against pollution of substrate itself, lifts the contamination resistance on its its surface during transport, production etc., can be widely applied to kitchen
Defend the production and processing of oil resistant baking vanish Integral ceiling product.
Embodiment
The key problem in technology of the present invention, one be by studying aluminium sheet continuous anodic oxidation technique, including tank liquor formula and electric current,
The parameters such as voltage, temperature, improve the adhesive force of aluminum oxide substrate and environmentally friendly oil resistant baking vanish.If oxide-film is too thick, for follow-up
Buckle processing and forming causes oxide-film to ftracture, and can have a strong impact on the service life of product, if oxide-film is too thin, can influence product
The antioxygenic property and hardness of itself；It is thus impossible to which single improve attachment by changing aluminium base surface oxidation film thickness
Power.Two be to carry out sealing of hole modification technology innovation, durability against pollution of the studying alumina substrate in the production process of baking vanish, and not
The adhesion strength between aluminum oxide substrate and oil resistant baking vanish can be reduced.
Step 1 of the present invention) in degreaser or cleaning agent specific kind, can select as needed.
