2SiO
3(water glass) waits other to add component is treatment soln, pass to certain electric current at normal temperatures, voltage carries out the fast anode oxidation, carry out sealing treatment with one of three kinds of methods provided by the invention then, thereby generate a kind of antifriction, anti-corrosion, weather-proof, the minute surface insulating oxide rete of surperficial visible light reflection high (about 85%).Present technique technology is simple, and is with low cost, the production efficiency height.
Description
The present invention relates to the anodizing of aluminium technology.
Usually anodizing of aluminium is carried out on aluminium, and the general time of this method is long, big energy-consuming.If will obtain the surface of high reflectance, also need carry out chemical rightenning or electrochemical etching, thereby technology is complicated, cost is also high.
The invention provides a kind of anodic oxidation new technology of aluminium plating membrane, the enforcement of present technique not only provides a kind of effective protective layer for aluminium plating membrane, but also can enlarge the range of application of anodizing technology.
The invention is characterized in that it is that the minute surface of aluminizing on nonmetal (being particularly useful for glass, pottery) base material generates one deck aluminum oxide dull face film through anodic oxidation treatment.Its technological process and operational condition are as follows:
1, preparation aluminium plating membrane
Aluminium film with vacuum plating unit evaporation one deck cleaning light on slick nonmetal basal body material surface.
2, the cleaning of aluminium plating membrane
The aluminium film for preparing generally need not clean, if there are fingerprint, greasy dirt, sweat stain etc. in the surface, available 1% oxalic acid solution cleans.Dry standby after the cleaning.
3, anodic oxidation treatment
Negative electrode adopts stereotype, and anode is processed of AM aluminum metallization film on nonmetal base material.Processed joins by smooth bright and clean aluminium sheet and anchor clamps.Should join with solution with processed aluminium sheet that joins.The condition of oxide treatment is as follows:

Solvent adopts distilled water or deionized water.
Operational condition: pass to direct current, current density 1.5～3.5A/dm
2, bath voltage 15～30V, 2～6 minutes time.Electric current should arrive rated value gradually.
4, sealing treatment
Workpiece after the anodic oxidation treatment after the water flushing, is removed the residuary water on surface, carries out sealing treatment.
Sealing treatment carries out one of by the following method:
(1) the confining liquid proportioning is:

3(water glass) 50～100g/l(water)
Solution temperature is 75～85 ℃, passes to direct current, and current density is controlled at 0.8～2.0A/dm
2, voltage control is at 20～50V, close process time 1～3 minute.
(3) confining liquid is
KCr
2O
45～15g/l(water)
Solution temperature is 75～85 ℃, close process time 10～25 minutes.
5, finished product cleans and is dry
Part in addition behind the sealing treatment, water cleans, and dries naturally then.
Aluminium film anodizing technology provided by the invention can generate a kind of antifriction, anti-corrosion, weatherable electrical isolation oxidation film layer at aluminium film surface, and this oxidation film layer surface energy keeps higher visible reflectance (about 85%).The specular material of the high stability that the employing present technique is made can be used as the reflecting material of solar concentrator etc.Simultaneously, it is simple that present technique has production technique, and less energy intensive is with low cost, characteristics such as production efficiency height.
