Description
Technical field
This utility model is about a kind of structure generating pattern on metal surface plating oxide-film, a kind of good
Rate is high and can generate the method for pattern and the structure thereof of multiple color in metal surface.
Background technology
Typically in order to give the colorful variation of metal appearance and retain metal appearance tactile impression, and can be antirust or prevent abrasion
Deng.The process for treating surface of metal chassis gradually attention.In the process for treating surface of metal chassis, with plating, chemistry
Plate or other application modes form functional metal layer in metal chassis, or produce various difference on metal chassis surface
The floral designs of level or word increase the sense of worth of product.
General electric plating method, is first to carry out anodic oxidation electroplating processes in metallic substrate surface, and general aluminium alloy holds very much
Oxidizable, though oxide layer has certain passivation, but the result of Prolonged exposure, oxide layer still can be peeled off, and loses protective effect, because of
The purpose of this anodising i.e. utilizes the characteristic that it is oxidizable, controls the generation of oxide layer by means of electrochemical method, to prevent aluminium
Oxidation further, to prevent aluminium from aoxidizing further, the engineering properties simultaneously increasing surface increases the engineering properties on surface simultaneously.
Another object is that, borrow difference chemical conversion reaction, produce various color and luster (color development) having improved aesthetic appearance.
And anodic oxidation electroplating processes, under practical situation, it is necessary in an electrolysis bath, (electrolytic solution usually dilutes sulfur
Acid) in, metal base (such as aluminum or aluminum alloy) workpiece being placed in anode, applies certain voltage and electricity, electric current passes through Metal Substrate
(anode) and electrode (negative electrode) between material.This will cause oxonium ion to be gathered in metallic substrate surface and will react and form one
Porous oxide coatings (anode oxide film), owing to anodising is be oxidized to epithelium (Conversion Coating) technology one
Kind, it is melted into epithelium according to the definition of ASTM and refers to utilization chemistry or electrochemical treatments, make metal surface generate one containing being somebody's turn to do
The skin membrane of metal ingredient, and the display skin membrane of anodising epithelium (anode oxide film) is actually in tracheid
(cellular tube) tissue, bottom it like bottom general test tube in arc-shaped, tracheid tissue then has multiple hole.
And after anodic oxidation electroplating processes, then this metal base 3 must be immersed and have (the leaching of the dye solution of solid color
Dye), but when the hole 11 of coloured this anode oxide film 1 of dye solution 2 then can be because of siphon principle, as it is shown in figure 1, dyestuff
Solution 2 in this hole 11 but also because the impact of siphon, therefore cannot make the dye solution of this color drop down onto this hole 11 or
Penetrate in this anode oxide film 1；
Further, since anodizing of aluminium film has a large amount of hole, aluminum surface to process its surface adsorption very by force, hands touches to be had
The sensation of viscous hands, therefore after coloring, for improving the anti-pollution and corrosion resistance of oxide-film, sealing of hole is requisite step
Suddenly.The sealing of hole of aluminium alloy profiled aluminium mainly has heat-sealing hole and two kinds of cold seal hole.
But, the program of above-mentioned coloring, if to contaminate another kind of color during Zhe Se, and it is not necessary to change color
Position then must use a resistance electricity ink to cover, and immerse to have in the dye solution of another color by this metal base again and soak
Dye, however this resistance its blocking effect of electricity ink the most as expected in good, therefore when immerse have in the dye solution of another color time,
It is not necessary to change the position of color it is possible to caught another kind of color, therefore when contaminating another kind of color, its yield will drop
As little as 60 ~ 75%, and if to contaminate another kind of color the most again, its yield more can be reduced to less than 30%, therefore this traditional
Mode, is not particularly suited for repeatedly contaminating the demand of different colours.
Therefore, if a metallic substrate surface can be designed generate the structure of pattern, it is possible to generate multiple in metal surface
Also not interfering with its yield during the pattern of color, and the pattern of generation multiple color, such this utility model should be one
Best solution.

Clock.
Afterwards, when to carry out primary coloring, as shown in Figure 3A, then must be by having (this spray of multiple ink gun
Ink head can be electric osmose formula, voltage-type, air blowing type or bubble type) ink-jet apparatus (not shown), foundation pattern to be formed,
Multiple holes 311 interior injection solid color or two prior to the ad-hoc location of the anode oxide film 31 on this metal base 3 surface
Plant the dye ink 4 that color is mixed above, as shown in FIG., after this dye ink 4 falls within this hole 311, can be because of gravity
The bottom that impact is sunken to downwards in this hole 311, and it is internal gradually to penetrate into this anode oxide film 31；
And the ink that the dye ink that this utility model is injected is metal osmosis type, the ink of this metal osmosis type is by black
Tryptophol dissolubility/fat-soluble solvent type ink, green alcohol-soluble/fat-soluble solvent type ink, red alcohol-soluble/fat-soluble solvent type
Ink and yellow alcohol-soluble/fat-soluble solvent type ink are formed；
Coming is then the program of second time coloring again, as shown in Figure 3 B, then add successively the dye ink 5 of different colours, 6,
7, and this dye ink 5,6,7 can precipitate downwards because of the impact of gravity, therefore this dye ink 5 can be made, 7 and dye ink
The color of 4 mixes alternately, and another side is then that this dye ink 6 mixes alternately with the color of dye ink 4, and color is the ripest
After one-tenth as shown in Figure 3 C, this dye ink 5,7 then can form dye ink 5 ', dye ink 6 and dye ink with dye ink 4
4 mixing then can form dye ink 6 ', and from figure, this anode oxide film 31 is the most respectively by dye ink 5 ', dye ink 4
And dye ink 6 ' to penetrate into and separate be three district's colors；
But owing to the dye ink water yield can flood outside this hole 311 too much, therefore this anode oxide film 31 surface must be removed
Excess dyestuff ink, and the pattern after removing is as shown in Figure 3 D, afterwards, in order to make dye ink 5 ', dye ink 6 ' also have illicit sexual relations
It is internal that material ink 4 can reside in this hole 311, after using alcohols or net washing water to remove excess dyestuff ink, it is necessary to enter again
Anodic oxidation sealing pores of row, but this anodic oxidation sealing pores have to add nickeliferous or containing chromium hole sealing agent
(such as DX-500 or RHS difficult to understand wild etc.) and be heated to 90 ~ 95 DEG C, so that this anode oxide film 31 surface and this dye ink 5 ',
Dye ink 4, dye ink 6 ' surface can regeneration one sealing of hole anode oxide film 32, with by this anode oxide film 31 surface
Hole 311 top seals, and the pattern after sealing of hole is as shown in FIGURE 3 E.
The structure generating pattern on metal surface plating oxide-film provided by the utility model, with other prior aries
When being compared to each other, its advantage is as follows:
This utility model can generate the pattern of multiple color in metal surface, and generates the process of the pattern of multiple color
In do not interfere with its yield yet.
This utility model is disclosed above by the above embodiments, and so it is not limited to this utility model, any
It is familiar with this technical field tool usually intellectual, understands the aforesaid technical characteristic of this utility model and embodiment, and not
Depart from spirit and scope of the present utility model, when making a little change and retouching, patent protection the most of the present utility model
Scope must be depending on being as the criterion that this specification appended claims is defined.
