Description

Metal surface plating oxide-film generates the structure of space pattern

Technical field

This utility model is the structure generating space pattern about a kind of 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 electric current, 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 circular arc, 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 tradition Mode, be not particularly suited for repeatedly contaminating the demand of different colours.

Therefore, if a metallic substrate surface can be designed generate method and the structure thereof of pattern, it is possible in metal surface Do not interfere with its yield during generating the pattern of multiple color, and the pattern of generation multiple color, in addition, more can yet Enough pattern position in anode oxide film surface present third dimension, and so this creation should be a best solution.
