Description
Technical field
Alumina technical field of the present invention, specifically, being related to a kind of sealer and processing method for alumina.
Background technique
Aluminium and its alloy material have a series of excellent physics and chemical property, can be used for construction material, electronic product,
Cosmetics packaging material etc..In use, widely being handled using anodizing technology aluminium material surface in the industry, to reach
Decorative and durability requirement.It specifically, is the alloy of aluminium or aluminium to be immersed in acid solution, while applying direct current
Electricity, under the action of the two is common, electrochemical change occurs for aluminum alloy surface, generates porous anode film layer, the film layer it is more
Permeability can adsorb the dyestuff of organic or inorganic, reach the decorative effect to aluminum component.But meanwhile the porosity can adsorb other again
It is dirty, and corrosion resistance is relatively low, so after anodic oxidation of aluminiun materials completion, in spite of coloring treatment is carried out, finally all
It needs to carry out closed processing to aluminium anodes film layer.
Common method for sealing mainly have boiling water sealing hole, steam sealing of hole, nickel salt sealing of hole, without nickel liquid medicine sealing of hole.Waste water sealing of hole
Main problem with steam sealing of hole is that energy consumption is higher, and the requirement to water quality is high, is easy to appear sealing of hole ash, at present industrial production
In almost without people use.Nickel salt sealing of hole is due to its stay in grade, and low in cost, closed effect is preferable, and to water quality requirement
It is not high, it is easy to the reasons such as construction, is widely used in the industrial production at present；But since nickel salt pollutes environment, thereby increases and it is possible to meeting
Skin allergy is caused, so the appearance of market urgently new product solves the problems, such as industry.
Then the sealer without nickel comes into being, but product on the market at present, often closed effect and nickel salt phase
Than greatly differing from each other, show that closing stream color is serious, consistency is unable to control, and the product patience after closing is poor including corrosion-resistant
Property, ultraviolet resistance and stain resistance performance comparison nickel salt closing all differ more.
But there is following drawback using nickeliferous sealer:
1. largely having very big pollution to water body and natural environment using nickel salt, nickeliferous compound is by world health
Tissue is included in a kind of carcinogenic substance.
2. needing to heat the solution containing nickel salt in closing, can constantly there are steam generation, Gong Renchang in workshop
Phase works in such a case, has very big injury to health.
3. nickel salt can remain in aluminum alloy surface after closing, client can directly carry out skin contact when in use, lead
Cause the generation of allergic reaction and fash.
And if using the sealer for being free of nickel salt, although the above problem will not generate, closed alloy product,
Color can be largely lost, and indices (corrosion-resistant, stain resistance, the performances such as UV resistant) are all unable to satisfy client's need after closing
It wants.
Summary of the invention
The purpose of the present invention is overcoming above-mentioned the deficiencies in the prior art, provide it is a kind of without nickel salt and seal quality it is good
The pre- sealer and processing method for alumina.
To achieve the goals above, the present invention adopts the following technical scheme:

Potassium fluoride 0.001-10g,
Sodium fluoride 0.001-10g,
Thiocarbamide 0.001-10g.
Preferably, in the above-mentioned pre- sealer for alumina, the water-soluble molybdenum salt is molybdenum trisulfate, acetic acid
The mixture of one or more of molybdenum, nitric acid molybdenum, sodium molybdate, potassium molybdate.
Preferably, in the above-mentioned pre- sealer for alumina, sodium fluozirconate, fluorine are also added in each liter of water
Metatitanic acid or potassium fluotitanate, additive amount are 0.001-10g, 0.001-10g, 0.001-10g respectively.
The method handled using above-mentioned pre- sealer aluminium alloy includes the following steps: to carry out to aluminium alloy
After anodic oxidation and dyeing, first being handled with the pre- sealer, it is 10s-1200s using the time that treatment temperature, which is 0-50 DEG C,
Handle pH value: 1-5.5.
Compared with prior art, the invention has the following beneficial effects:
The present invention passes through many experiments, a kind of pre- sealer for alumina has been invented, after the pre- sealer
No nickel sealer processing is carried out again, stream color of the aluminium oxidation workpiece in pre- closing and closed process can be effectively reduced, in weightlessness
Aspect reaches more than traditional nickel salt sealing effect, and far superior to national standard 30mg/dm2.Patience test can pass through master
Most of patience test of manufacturer is flowed, while can also obtain outstanding ultraviolet-resistant performance, is had a extensive future.
