Abstract
The chemical treatment method on a kind of aluminium surface, through the photographing imaging acid corrosion, anticorrosion with painting erosion layer provides a kind of not only corrosion-resistant but also can decorate the aluminum alloy plate materials of usefulness again.It is low that this treatment process has a cost, and technology is simple, easy to operate, and is pollution-free; advantages such as it is low to consume energy, the decorative pattern on aluminium surface is changeable, can be landscape painting, portrait, geometricdrawing etc.; aluminium sheet physical strength height, the protective membrane erosion resistance on surface is strong, does not rupture during mechanical workout; can be used for inner container of electric refrigerator; senior decoration is (as luxurious elevator interior trim, hotel, meeting room; furniture decoration etc.), be comparatively ideal decorative materials.
Description
The invention belongs to metal surface treating method.
The present invention can be used for the surface treatment of aluminium alloy.At present, the aluminium that domestic many stars inner container of electric refrigerator is used has attractive in appearance and corrosion resistance in order to make it, the general method that adopts machinery to the rod embossing, and the technical requirements height, the equipment complexity, China's used this aluminium at present all relies on import.Surface treatment to aluminium, can also use chemical process,, surface of aluminum plate be corroded with alkaline solution as Japanese Patent Jp60-159146, carry out chemical rightenning again, improve the luminance brightness on decorative pattern surface, but handle the aluminium sheet that obtains in this way, surface oxidation blackening easily, generally must further adopt processing such as anodizing, chromaking, parco-lubrizing, this operating procedure is complicated, and the aluminium sheet pattern dullness that obtains, and erosion resistance is not strong.
The objective of the invention is to decorate the aluminum alloy plate materials of usefulness again in order to provide a kind of both corrosion-resistant.
The present invention is that the resist that adopts a photographic plate and a class to have photobehavior cooperatively interacts, and after exposure, developing to picture, in the electing property corrosion of aluminium surface, carves various patterns with the method for sour microcorrosion.As adjacent nitrine quinones, cause the photochemistry Decomposition through uv-exposure post-absorption energy, change the material that can be dissolved in developing solution into.The five-membered ring ketene compound generates joint yl carboxylic acid derivative and is dissolved in developing solution after hydrolysis for another example; just expose after the development and treat the corrosive zone; realized selective corrosion; use polymeric membrane again; with its surface-crosslinked polymeric membrane that is solidified into continuous whole, reach the purpose on protection aluminium surface as the versamid 900 class.
Specific operation process of the present invention is: spraying has the sensitization liquid of etch resistant properties on aluminium sheet, oven dry, put egative film, ultraviolet exposure imaging, the back acid corrosion of developing, do the re-expose imaging with ultraviolet ray again, use acid corrosion after developing, make re-expose with ultraviolet ray again, purpose is to remove photosensory membrane, clean, at last handle surperficial anticorrosion with painting film.
Adopt the present invention to handle the aluminium surface, it is low to have a cost, and technology is simple; easy to operate, pollution-free, advantage such as it is low to consume energy; the aluminium surface detail that processing obtains is changeable, can be landscape painting, portrait; geometricdrawing etc., and surface-brightening is plentiful transparent according to the people; the physical strength height, the protective membrane erosion resistance on surface is strong, does not rupture during mechanical workout; can be used for inner container of electric refrigerator, senior decoration (as luxurious elevator interior trim, hotel, meeting room, furniture decoration etc.) is comparatively ideal decorative materials.To the original aluminum panel material,, can be aluminium sheet and aluminium alloy plate without any restriction.
Embodiment: with an ordinary aluminum plate, doing the surface cleans, remove the greasy dirt that mechanical workout stays, carry out high surface finish, with concentration is that 20～25(is coated with-4 densitometers) commercially available Ps version sensitization liquid add thinner, be sprayed on surface of aluminum plate to be processed equably, the aluminium sheet that sprays sensitization liquid is put 5 minutes film forming of baking in 60 ℃～80 ℃ incubators, dapple template (plate) is lain on the aluminium sheet of having dried, egative film flattens with sheet glass, with ultraviolet lamp exposure 1～1.5 minute, make the decorative pattern photosensitive imaging on aluminium sheet on the egative film.The water-soluble liquid bath of aluminium sheet being put into 0.1～5% sodium hydroxide and 2～8% tertiary sodium phosphates developed for 2～60 seconds then, at this moment, black part photosensory membrane is left on the base plate, the light transmission part photosensory membrane is dissolved, it is 65～98% phosphoric acid liquid bath that aluminium sheet after developing is put into concentration, and temperature is 10～60 ℃, corrodes 2～3 minutes, at this moment, photosensory membrane dissolved the part exposed aluminium sheet be corroded.Aluminium sheet after acid corrosion again with ultraviolet lamp exposure 1～5 minute, with the photosensory membrane of dissolving part of exposure, is put into 0.1～5% sodium hydroxide and 2～8% trisodium phosphate aqueous solution grooves cleaned for 5～10 seconds again, the photosensory membrane that is exposed with dissolving.Wash the photosensory membrane residue that is attached on the aluminium sheet, spray versamid 900 varnish corrosion-resistant coating (concentration is 20～25 seconds) at last.With the aluminium sheet after handling, hardness is made on its surface, gloss, snappiness, tests such as corrosion resistance nature all meet national standard.

Claims (2)
1, a kind ofly chemically treated method is made on the aluminium surface with acid corrosion, it is characterized in that aluminium sheet with before the acid corrosion, spraying earlier has the sensitization liquid of etch resistant properties, behind exposure image, utilize the light and shade characteristics of egative film, to the electing property corrosion of aluminium surface, make re-expose with ultraviolet ray again with acid, remove photosensory membrane, at last the aluminium surface anticorrosion with painting film of handling well.
2, a kind of as the said aluminium chemical conversion treatment of claim 1 method, the sensitization liquid that it is characterized in that having etch resistant properties is commercially available Ps version sensitization liquid, after the spraying, with ultraviolet lamp exposure 1～1.5 minute, then aluminium sheet being put into 0.1～5% sodium hydroxide and 2～8% trisodium phosphate solutions developed 2～60 seconds, aluminium sheet after the development is put into 65～98% phosphoric acid liquid bath and was corroded 2～3 minutes, aluminium sheet after acid corrosion, again with ultraviolet lamp exposure 1～5 minute, put into above-mentioned sodium hydroxide and trisodium phosphate solution then and clean, spray versamid 900 varnish corrosion-resistant coating at last.
