Definitions
- the invention relates to a process for the continuous industrial production of aluminum alloy strips coated with a varnish, particularly suitable for obtaining photographic quality decors according to the technique of sublimation dry transfer from a support. and strips produced by this process.
- the image to be transferred is, in most cases, printed on a paper medium according to traditional printing techniques.
- said support is pressed against the material on which it is desired to transfer the sublimable image, for about 30 seconds at temperatures generally from 200 to 230 ° C.
- the constituents of the inks composing the image then pass directly from the solid state to the gaseous state and migrate towards the support to be printed on which they condense and are absorbed.
- the ink vapors return directly to the solid state.
- the application then spread to other materials including polymers and metals.
- anodizing treatment prior to transfer is mainly practiced.
- Claim 4 preferably refers to anodizing in a sulfuric medium; the description in column 4, lines 63 to 66 states that, after clogging for half an hour in boiling water, an operation known as boehmitage, the quality and clarity of the hue remain "acceptable".
- the transfer must be carried out in a short and relatively constant time after the anodization (preferably chained to the anodization) the pores clogging naturally by formation of hydrated alumina (Al 2 O 3 , (H 2 0) x).
- the thickness of the anode layer must be relatively large (more than 2 to 3 ⁇ m, or even 7 ⁇ m for blue and black) and of the sublimation operation by heating, it is common to see a cracking of this type of layer.
- the patent application FR 2,230,794 (Sublistatic Holding SA) filed in 1974 describes the application of this process, at a temperature between 140 and 300 ° C, preferably 180 to 230 ° C, on any rigid material made up or previously coated with epoxy resins, transparent or colored.
- Aluminum is cited, among a large amount of other media, through home appliances, furniture, automotive sheets, but without any indication of the surface treatment prior to allow adhesion of said epoxy resins.
- the treatment in question consists of either conventional anodizing or chemical conversion. to obtain in order to fix the resin, a porous layer at least at the surface, with all the disadvantages already described as to this type of surface.
- Patent EP 0 012 831 B1 (Fromson, Howard A.), filed in 1979, describes a sublimatic transfer process, at a temperature preferably between 121 and 218 ° C., on an aluminum substrate comprising a porous oxide layer not clogged and coated with a transparent or colored polymer. The pigments pass through the polymer material and condense in this coating as well as in the pores of the anode layer.
- the Applicant has therefore sought to obtain a resistant support (both scratches and corrosion and aging in particular) allowing transfer by sublimation without cracking or visible modification of the color and the definition of the transferred image (so-called photographic quality ) with a non-limiting palette of pigments, and allowing subsequent folding or shaping operations without apparent deterioration.
- the subject of the invention is a method of continuously manufacturing an optimized surface aluminum alloy strip for transferring a sublimable decoration from a temporary support, comprising:
- this step may be preceded by deoxidation, also called selective etching, in a phosphochromic medium of the previously formed oxide layer.
- deoxidation also called selective etching
- the selective pickling and electrolytic polishing steps can be repeated.
- the varnish is glossy, of the BASF type CI49-0005, or matt, of the type
- the subject of the invention is also the strip treated and coated according to the process or its variants above, thus prepared for application, after any cutting into sheets of said strip, to the transfer by sublimation, as well as the strip or sheet decorated after said transfer from a temporary support.
- the invention consists in using aluminum alloy strips of "brilliant" or “high gloss” quality, subjecting them continuously, after optional degreasing and chemical or electrolytic polishing, to a thin-layer anodizing treatment. thickness less than 1 micron followed by a pore-sealing operation by continuous immersion preferably in boiling water, operation known as boehmitage, before coating, preferably continuously according to the coating technique of the type known by the person skilled in the art, under the name “coil coating", of a transparent varnish based on a mixture of polyester and polyurethane.
- the anodic layer with a non-porous surface, obtained before final varnishing, can advantageously be a compact layer of the barrier type obtained by the HELIA® process, which is the subject of patent EP 0 745 703 of the Applicant, applied to strips of "brilliant" or “high gloss” quality and whose main phases, after possible degreasing, are recalled below:
- the barrier layer thus formed although compact and having no pores in the sense that is meant for non-clogged layers, behaved like a thin anodic layer (less than 1 ⁇ m) with respect to the adhesion of the varnish and its resistance to scratching and tearing during subsequent folding or shaping operations.
- the varnish may be glossy, for example of the BASF CI49-0005 type, in order to keep on the final product a mirror-polished or matte appearance, for example of the BASF type CI49- 0004, for a satin appearance.
- This feature also expands the palette of usable inks or pigments.
- the fineness of the anodic layer ensures the absence of visible cracking during the sublimation operation and also has a very positive influence on the characteristics of folding and shaping of the final product.
- Alcan-Singen "1085 Surface 310" high gloss aluminum alloy coils and Amag “1085 126.2” coils were degreased and then treated using the HELIA® variant 1 of EP 0 745 703 (ie electrolytic polishing, phosphochromic deoxidation, micro polishing with barrier layer).
- Characterizations included optical measurements, varnish adhesion and salt spray corrosion resistance. at.
- Optical measurements they focused on the total reflectivity Rt and the diffuse reflectivity Rd by Ulbricht sphere according to DIN 5036, as well as on the specular reflectivity at 60 degrees in the long and rolling directions,
- Matte varnish offers an interesting alternative corresponding to a satin aspect but with a high value of total reflectivity.
- Adhesion of the varnish The adhesion of the coating to the substrate corresponds in both cases to the ISO 2409 (1992) class 0: perfectly smooth incisions edges, none of the grid squares detached.
- the characterizations included the same optical measurements, adhesion of the varnish and resistance to salt spray corrosion.
- the surface has as before all the characteristics of the mirror polish, namely high values of the total and specular reflectivity, associated with a low value of diffuse reflectivity.
- Matt varnish offers, in the same way as for the previous tests, an interesting alternative corresponding to a satin aspect but with a high value of the total reflectivity. b. Adhesion of the varnish:
