Description

Metallic surface anode treatment method
Technical field
The present invention relates to a kind of metallic surface anode treatment method, relate in particular to a kind of multicolour anode treatment method that can be used for curved surface.
Background technology
Aluminium, titanium and alloy material thereof be because of having advantages such as intensity height, light weight, and be widely used in fields such as aviation, electronics, communication.In order further to improve its surface quality and visual effect, industry adopts anode processing technique or spraying to reach usually.As United States Patent (USP) the 5th, 215, disclosed a kind of trailing of titanium base object for No. 606, before to the object spraying, at first under vacuum, add hot basal body, its surface microstructure is grown up, carry out anodizing then, and by changing the two poles of the earth voltage control surface oxide layer color, the oxide thickness homogeneous that this method obtains lacks the convexo-concave stereoscopic sensation.Existing anode processing technique also has anodizing and the repeatedly painted method that obtains the oxide film of different color of adopting repeatedly, though this method can obtain the multicolour oxide film in the metallic surface, but each processing can only be carried out at grade, can't disposablely obtain successive on curved surface and have relief multi color pattern.And the rule pattern that sprays paint is simple, a little less than the soft edge, paint film adhesion.
Summary of the invention
In view of this, be necessary to provide a kind of and can on curved surface, obtain the metallic surface anode treatment method that successive has relief multi color pattern.
A kind of metallic surface anode treatment method is used to handle aluminium, aluminium alloy and titanium alloy-based surface, and it may further comprise the steps:
(1) described matrix is carried out anodizing, to form an oxide film at matrix surface;
(2) this oxide film is carried out painted processing;
(3) spraying printing ink covers its surperficial oxide film fully on this matrix;
(4) film film that will be manufactured with required pattern is affixed on the described metallic matrix that is coated with printing ink;
(5) exposure-processed is to solidify the printing ink that is not blocked by the pattern part on the film film;
(6) remove uncured printing ink;
(7) remove the oxide film that is not hidden by printing ink;
(8) this matrix is carried out the anodizing second time;
(9) oxide film that obtains after the anodizing this second time is carried out painted processing;
(10) remove residue and cover printing ink;
(11) repeating step (3) ~ (10).
Compared to prior art, the inventive method overlays by the film film vacuum that will be manufactured with required pattern is covering on the oxide film printing ink, solidify a part of printing ink by exposure earlier, the method of taking off the uncured printing ink of part of developing again accurately marks off the zone that need carry out once more anodizing, makes pattern meticulousr, clear.The film film that this method is used not only can be used to overlay a certain plane in metallic matrix, and, it can deform, thereby also can be used for overlaying on the curved surface of metallic matrix, thereby can have relief pattern by disposable whole surface acquisition successive at metallic matrix.Simultaneously, make the metallic surface of acquisition have many lines texture pattern that height rises and falls by the condition that changes each anodizing.
Embodiment
Preferred embodiment metallic surface anode treatment method of the present invention is treated to example by the anode surface to a metallic matrix and describes, and comprises the steps:
(1) with the solution clean metal matrix that contains the respective metal grease-removing agent, then this metallic matrix being placed phosphoric acid and vitriolic solution to carry out chemical rightenning handles, metallic matrix desmut after then this chemical rightenning being handled with the solution that contains nitric acid, the film of one deck black that forms on its surface when handling because of above-mentioned chemical rightenning to remove workpiece.
(2) metallic matrix is carried out anodizing, to form oxide film at metal base surface.Contain the sulfuric acid of 180 ~ 200g/L in this step in the anode treatment soln and less than the aluminum ion of 20g/L, processes voltage is 11 ~ 13V, at room temperature handles 30 ~ 50 minutes.
(3) metallic matrix after the above-mentioned anodizing is carried out adsorption coloring or chemical stain processing.
(4) metallic matrix after the above-mentioned painted processing being carried out sealing of hole handles to improve the anti-pollution and corrosion resistance of its surface film oxide.
(5) spraying printing ink and cover its surface film oxide fully on metallic matrix.Described printing ink is photosensitive-ink, and ink thickness is 10 ~ 50 μ m.
(6) film film vacuum that will be manufactured with required pattern overlays on the described metallic matrix that is coated with printing ink.This step adopts a vacuum generator, makes to form a vacuum between film film and the metallic matrix, and film film plaster is invested on the metal base surface.Figuratum part has been exposed and has been black on this film film, and the part that does not have pattern is transparent.
(7) exposure-processed is to solidify the printing ink that is not blocked by the pattern part on the film film.This exposure-processed step is used astigmatic exposure machine, and exposure energy is 100 ~ 150mj/cm 2, exposure intensity is 5 ~ 25, the ink solidification that is not blocked on the metallic matrix after this step process by the pattern on the film film, and the printing ink that is blocked by the pattern on the film film does not solidify.
(8) remove described vacuum state and make film film break away from metallic matrix, the uncured printing ink of dissolving in a developing solution.
(9) oxide film that is not hidden by printing ink is removed in laser sculpture or chemical milling.Chemical etching liquor is 60 ℃, the sodium hydroxide solution of 40g/L in this step, and etching period is 10 ~ 60 seconds.
(10) metallic matrix behind chemical rightenning and the desmut is carried out the anodizing second time, this chemical rightenning is described identical with step (1) with the desmut method.
(11) oxide film that obtains after the anodizing second time is carried out adsorption coloring or chemical stain processing.
(12) oxide film that obtains after the anodizing second time being carried out sealing of hole handles.
(13) remove remaining printing ink, the pattern that can on this metallic matrix, obtain to have clear-cut, stereoscopic sensation is strong of covering with the special-purpose stripper of printing ink.
Be appreciated that the above step of repetition (5) to (12), can obtain more multicoloured pattern in this metallic matrix.
Be appreciated that can be by changing each anodizing condition such as anodizing time make the thickness difference of the oxide film that each anodizing obtains, thereby can make whole metallic surface obtain to have the solid pattern that height rises and falls.
The inventive method is applicable to the surface treatment of metallic matrixes such as aluminium, aluminium alloy and titanium alloy.The inventive method overlays by the film film vacuum that will be manufactured with required pattern is covering on the oxide film printing ink, solidify a part of printing ink earlier by exposing, the method take off the uncured printing ink of part of developing again accurately marks off once more the zone of anodizing, makes pattern meticulousr, clear.The film film that this method is used not only can be used to overlay a certain plane in metallic matrix, and, it can deform, thereby also can be used for overlaying on the curved surface of metallic matrix, thereby can have relief pattern by disposable whole surface acquisition successive at metallic matrix.Simultaneously, make the metallic surface of acquisition have many lines texture pattern that height rises and falls by the condition that changes each anodizing.
