Embodiment
Technical scheme is further illustrated below by embodiment.
Embodiment 1
The autoxidation aluminium on aluminum products surface was not only soft but also thin, and corrosion resistance is poor, it is impossible to be more not suitable for as effective overcoat
Color.Therefore can be in product surface manufacturing artificial oxygenerating film, as product surface diaphragm, relative to nature in modern industry
Aluminum oxide, good corrosion resistance, hardness is good, and thickness is big, colours.
Aluminium alloy is done after anodic oxidation, and very strong metal-like can be presented, and color is varied.However, common
The product surface that anodic oxidation is made all is the effect that plane is presented, and coloring is more single and stiff, and product is just without more
Sample.
Therefore the invention provides a kind of process of surface treatment for realizing electronic product 3D effect, by product table face
Subregion or Zone Full carry out laser carving so that product surface is in 3D stereoeffects, and carries out sun to the product surface after laser carving
Pole aoxidizes to form the anode oxide film with resistance to corrosion and adsorption capacity.
The processing of the laser carving is the high-strength focused laser beam product irradiation surface launched by using laser, causes production
Corresponding Chemical Physics change occurs for the material on product surface, so that by planning of the planar structure of product surface according to industrial design
Form the three-dimensional structure with different levels.
As one of the preferred embodiments of the present invention, comprise the following steps：
Step 1: plane lapping：The vestige of processing or mould can be left when product surface is untreated, in its plane,
Plane lapping is carried out to the surface of product, to remove fault unnecessary on product surface and cut, the flatness of setting is reached.
Step 2: oil removing：Oil removing is carried out to product surface using alkaline solution, can by animal oil and vegetable oil stinging formation
Dissolubility soap and except degreasing；Because greasy dirt can reduce the adhesive force of anode oxide film, the entirety of anode oxide film is had an effect on
Quality, so must clean up.In order that oil removing ratio is more thoroughly, cleaning way carries out oil removing twice for use preferably.
Step 3: alkali is stung：The flash of product surface is removed by industrial soda, adjust workpiece surface material thickness, it is uniform,
Bright dark degree, so that the change of this material is smooth；Alkali sting be chemical polishing another important pretreatment mode, alkali is stung can
With the thickness for adjusting workpiece surface material, uniform, bright dark degree, not pretreated aluminium is to be unable to anodic oxidation and coloring
's.
In addition, aluminium and its alloy surface are readily generated one layer of very thin pellumina in atmosphere, (thickness is about 0.01-
0.02um), there is certain resistance to corrosion in an atmosphere, but this oxide-film is loose porous, uneven, resistance to corrosion is not
By force, stain is becomed easily infected by.Meanwhile, product surface production when around can produce flash, the oxygen of aluminium can be removed by alkali lye
Change film and flash.
Thrown Step 4: changing：Product surface is polished using phosphoric acid solution or phosphosulfate mixed liquor；To obtain bloom
The temperature that processing is thrown in change in the surface of brightness, step 4 is 95-105 DEG C, processing time 20-120 second.
Step 5: an anodic oxidation：Anodized is carried out to product surface using sulfuric acid solution, to be compared
Product surface has more preferable resistance to corrosion and the anode oxide film of adsorption capacity；The oxidation for the aluminium that anodizing process with sulfuric acid as major salt is obtained
Film layer appearance colorless is transparent, and thickness is 5-20um, and hardness is high, and hole is more, and adsorptivity is strong, is conducive to dyeing, after Seal treatment,
With higher resistance to corrosion, it is mainly used in protection and decorative purpose, the process of film forming is water electrolysis process.
The concentration of sulfuric acid is 180-220g/l in step 5, and voltage is 8-15V, and temperature is 18-22 DEG C, and the time is 20-
60M.The oxide-film that anodic oxidation is formed is interim oxide-film, for preventing that product surface is certainly in process of production
So aoxidize or be easier to be stained.
Step 6: laser carving：The high-strength focused laser beam launched using laser so that product surface is according to industrial design
Requirement different levels and structure is presented；The beam distribution and energy size of the generating laser, can be according to specific industry
Design requirement is adjusted accordingly.
Step 7: sandblasting：Blasting treatment is carried out to the product surface structure after laser carving, made using the impact of high speed sand flow
With the surface for clearing up and being roughened product, impact and shear action due to abrasive material to workpiece surface make the surface of workpiece obtain one
Fixed cleannes and different roughness, making the mechanical performance of workpiece surface is improved, therefore improves the antifatigue of workpiece
Property, its adhesive force between coating is added, the durability of film is extended, the levelling and decoration of coating is also beneficial to.
The sandblasting is zircon sand, glass sand or steel ball；The pressure of sandblasting is 2kg/cm in the step 72, the rule of sandblasting
Lattice are 150-210 mesh.
Step 8: strip：Strip processing is carried out to product surface by decoating liquid, with facing formed in removal process five
The anode oxide film of when property and because of the technique of sandblasting and laser carving self-assembling formation oxide-film；In order to passed through in product surface
Go through after step 6 and step 7, complete after 3D shaping structures, further obtain complete anode oxide film.
Step 9: two-step anodization：Anodized is carried out to product surface using sulfuric acid so that with 3D effect
Product surface on produce the anode oxide film with resistance to corrosion and adsorption capacity.The aluminium that anodizing process with sulfuric acid as major salt is obtained
Oxidation film layer appearance colorless is transparent, and thickness is 5-20um, and hardness is high, and hole is more, and adsorptivity is strong, is conducive to dyeing.
As one of the preferred embodiments of the present invention, in addition to Step 11: sealing pores：Anode oxide film is sunk
Product has the micropore sealing pores of dyestuff, to keep fast colours degree.But also can have workpiece prevents fat from printing, color spot and oil
The ability that fat is contaminated.It is further that sealing pores are carried out to anode oxide film using nickel acetate.
In summary, by the way that the subregion of product surface or Zone Full are carried out after laser carving, obtain with 3D structures
Product surface, and further do anodic oxidation, obtain the anodic oxidation product of 3D stereoeffects.Enrich product realization side
Formula, reaches and pursues ultimate attainment effect.The PROCESS FOR TREATMENT of anodic oxidation twice so that product surface maintain preferable smoothness and
Flatness, with good resistance to corrosion, improves the quality of product.
The technical principle of the present invention is described above in association with specific embodiment.These descriptions are intended merely to explain the present invention's
Principle, and limiting the scope of the invention can not be construed in any way.Based on explanation herein, the technology of this area
Personnel, which would not require any inventive effort, can associate other embodiments of the present invention, and these modes are fallen within
