Description
Technical field
The present invention relates to field of metal surface treatment technology, and in particular to a kind of noninductive light anodic process.
Background technology
Aluminium and its alloy have intensity high, heat conduction and conduct electricity very well, color and luster is attractive in appearance, nonmagnetic, decay resistance and
Plasticity and processability is good, advantage without black brittleness, is a kind of nonferrous materials with premium properties, current aluminium and its
Alloy is widely used in Aero-Space, building, automobile, mechanical performance and civilian art metal part；But some performances of aluminium are also not
It is too preferable, such as surface property of hardness, wearability and corrosion resistance；To overcome the shortcoming of aluminum alloy surface aspect of performance, it is also
It is the most frequently used salvo to improve the anodic oxidation in protective, ornamental and feature, the sufacing of aluminium.
The anodic oxidation of aluminium and aluminium alloy is that aluminium and aluminium alloy are placed in the process handled in electrolyte as anode,
After anodic oxidation, aluminium surface can generate the oxide-film that thickness is several microns and hundreds of microns, and its surface is entered so as to reach
The effect of row protection, general traditional anode oxidation coloration can only obtain single coloring effect, and in order that outer after anodic oxidation
Sight surface is good-looking, and at present, the expression way of aluminum alloy surface LOGO patterns includes the side of laser carving, punching press, printing or OEM
Formula represents, but laser carving mode has Shamian Island on LOGO patterns, and color and luster is dim, and two kinds of only dull colors；Punching press
Mode can have raised or recessed on the surface, and appearance color is single, unsightly；Printing has the marking of ink and easily comes off
Color, reduction shelf life of products, OEM mode rat, outward appearance is more simple and easily comes off, reduction product quality and class.
Existing anodizing technology is general to do anodic oxidation to realize to aluminium table using 5 series and 6 series alloys
The protection in face, but have the following disadvantages：
1st, 5 be with 6 line aluminium alloy compositions due to, 5 be relatively low with the 6 line aluminium alloy strengths of materials, in structure design by
To many limitations；
2nd, the high strength alumin ium alloy intensity of 7 series is high, still, in the prior art, and the high strength alumin ium alloy of 7 series is typically using electrophoresis etc.
Others surface treatment, such as carries out anodic oxidation, its surface easily generates material line, outer light performance to the high strength alumin ium alloy of 7 series
Power is not strong.
Therefore, a kind of new technology for aluminum alloy surface anodic oxidation is needed badly, carrying out quasi-complement, product is not in the market
Foot.
The content of the invention
In view of this, in view of the existing deficiencies of the prior art, its main purpose is to provide that a kind of color is various, hold to the present invention
Long property is good, good corrosion resistance, high light, the noninductive bright anodizing technique of aluminium alloy of no concave-convex sense.
To achieve the above object, the present invention is using following technical scheme：A kind of noninductive light anode oxidation process, including
Following steps：
1）Raw material aluminium sheet is polished：Scar, sisal polishing, cotton dolly is gone to receive light using 180# ~ 400# emery cloths silk；
2）Once oxidation：Aluminium sheet after polishing is aoxidized 5 ~ 20 points in degreasing bath in washing-oxidation trough in cleaning-rinsing bowl
--- sealing of hole in sealing of hole groove -- is washed in clock-rinse bath to dry in washing-baking box in rinse bath；
3）Ink covers：Adjust ink -- frame web plate -- debugging position -- 25 ~ 60 minutes temperature 60 of printing-ink -- inspections -- baking ~
100°；
4）Move back oxidation：Move back oxide scale film --- washing --- baking；It is described move back oxide scale film with move back oxidation solution include NaOH,
Sodium nitrate and water, its mol ratio are NaOH：Sodium nitrate：Water=0.01:1:3 ~ 5, oxidization time is moved back for 20 ~ 30 seconds；
5）Sandblasting：Put tool -- adjusting sand-blasting gun -- sandblasting；The sand-blasting gun spray angle is 45 ~ 60 °, and pressure is 1.5 ~ 4KG, spray
The distance of sand rifle and product is 10 ~ 30cm, 80 ~ 150# of model steel sands or glass sand；
6）Secondary oxidation：Degreasing bath cleans -- washing -- 5 ~ 30S of alkali cleaning, 90 ~ 110 ° of temperature, and -- washing --- neutralizes -- washing -- acid
Washing 5 ~ 30S, 90 ~ 110 ° of temperature, -- washing -- neutralizes and -- washes and -- aoxidize 5 ~ 20 minutes and -- wash -- washing -- and dye 1 ~ 40 point
-- -- --- sealing of hole -- washing -- is toasted clock for washing for washing；
7）De-oiling ink：-- washing -- drying -- is checked de-oiling ink；
8）Check.
The step 3）The ink includes：
Acrylic resin： 17-27%；
Urethane： 18-24%；
Isopropyl acetone： 13-19%；
Cyclohexanone： 10-18%；
Acids solvent： 5-11% ；
Ethyl benzene solvent： 13-18%.
The step 7）The black agent of de-oiling used includes phosphoric acid, nitric acid, citric acid, nitric acid hydrogen sodium, water, and its proportioning is
Phosphoric acid：Nitric acid：Citric acid：Nitric acid hydrogen sodium：Water=13:32:9:7:30~60.
The acids solvent is acetate solvate.
The present invention has clear advantage and beneficial effect compared with prior art：Through repetition test, this programme technology is adopted
With corresponding printing-ink and under the process conditions of this project, aluminum alloy surface strong bonded that can be with oxidized mistake,
Can not occur any physical reactions with the follow-up oxide scale film solution that moves back simultaneously, and be removed by the de- printing ink solvent of correspondence configuration
Printing-ink, and the oxide-film in secondary oxidation is not influenceed, so that noninductive light pattern is made.
Meanwhile, the technological parameter obtained by blasting craft is after repetition test in technical solution of the present invention can be carried effectively
The effect of high product secondary oxidation, while influence of the reduction to masking ink layer, obtains the noninductive pattern of surface-brightening.
