Definitions
- the invention relates to a method for the partial matting of UV lacquer layers by means of an excimer radiator.
- UV lacquer coatings generally have high resistance and resistance to mechanical, physical and chemical influences, in particular high scratch resistance.
- the surface of such lacquer layers after curing usually appears shiny or dull, depending on the composition of the lacquer used.
- this is off EP 0 338 221 A a film web consisting of at least two layers, which, inter alia, has a 3 to 30 .mu.m thick acrylate lacquer layer produced using at least one monomeric, di- and / or trimeric acrylate, which consists of a matt lacquer based on an acrylate mixture which passes through Reaction of at least one prepolymeric acrylate with at least one monomeric, di- and / or trimeric acrylate, wherein the lacquer per 100 parts by weight of the acrylate (calculated without any additive, processing aid or blowing agent), 20- 60 parts by weight a matting agent or matting agent mixture, 1-10 parts by weight of a UV initiator or UV initiator mixture, 0-10 parts by weight of a blowing agent or blowing agent mixture contains or consists thereof.
- matting results from the addition of a matting agent in the paint formulation. This achieves a so-called volume matting, ie the matting agent is more or less homogeneous in the paint matrix distributed there and generates a light scattering, which is perceived as matting.
- EP 0 706 834 A is a process for the production of UV-curable lacquer-coated sheet-like support materials with a matt or glossy surface known, the degree of matting of the UV coating is adjusted by the addition of mono- and / or difunctional monomers, and for the UV curing multiple radiation sources defined wavelength range can be used. The matting that results here is due to the special shape of the surface during curing. The remaining lacquer layer is not changed. In this case one speaks of a surface matting.
- D1 From the DE 198 10 455 A1 (D1) discloses a device and a method for curing a UV lacquer layer on a substrate, wherein the illumination device used comprises a light source, a barrier in which at least one heat-absorbing body is arranged, and reflectors.
- the carrier film can first be coated over the whole area with a scratch-resistant UV lacquer layer and then partially coated with a matt UV lacquer layer.
- two steps are necessary and there is a difference in thickness between the frosted and glossy spots.
- the object of the invention was to provide a method in which no full-surface, but a partial matting of UV lacquer layers in a single operation is possible.
- the invention therefore provides a process for the partial matting of UV lacquer layers according to claim 1.
- a UV lacquer layer is first applied to a carrier substrate.
- carrier films are preferably flexible plastic films, for example of PI, PP, MOPP, PE, PPS, PEEK, PEK, PEI, PSU, PAEK, LCP, PEN, PBT, PET, PA, PC, COC, POM, ABS, PVC , PTFE, ETFE (ethylene tetrafluoroethylene), PFA (tetrafluoroethylene-perfluoropropyl vinyl ether fluorocopolymer), MFA (tetrafluoromethylene-perfluoropropyl vinyl ether fluorocopolymer), PTFE (polytetrafluoroethylene), PVF (polyvinyl fluoride), PVDF (polyvinylidene fluoride), and EFEP (ethylene oxide). Tetrafluoroethylene-hexafluoropropylene fluoroterpolymer).
- the carrier films preferably have a thickness of 5 to 700 .mu.m, preferably 5 to 200 .mu.m, particularly preferably 5 to 50 .mu.m.
- metal foils for example Al, Cu, Sn, Ni, Fe or stainless steel foils having a thickness of 5-200 ⁇ m, preferably 10 to 80 ⁇ m, particularly preferably 20-50 ⁇ m, may also serve as the carrier substrate.
- the films can also be surface-treated, coated or laminated, for example, with plastics or painted.
- thermally activated paper or composites with paper such as composites with plastics having a basis weight of 20 - 500 g / m 2 , preferably 40 - 200 g / m 2 . be used.
- woven or nonwovens such as continuous fiber webs, staple fiber webs and the like, which may optionally be needled or calendered, can be used as carrier substrates.
- fabrics or webs of plastics such as PP, PET, PA, PPS and the like, but it can also be woven or nonwovens of natural, optionally treated fibers, such as viscose fibers are used.
- the nonwovens or fabrics used have a weight per unit area of about 20 g / m 2 to 500 g / m 2 . If necessary, the nonwovens or fabrics must be surface-treated.
- All carrier substrates can be present as web-shaped substrates or as piece goods.
- the cargo may be, for example in the form of plates, tiles or other formats of optionally coated wood, plastic, metal, ceramics and the like.
- the thickness of these substrates is usually a few mm or cm.
- First layers may already be applied to the carrier substrate, e.g. Lacquer or metal layers which cause an optical effect (color, color effects, gloss, reflection) or have functional properties (adhesion, wetting of the UV lacquer layer, electrical conductivity, optically active, in particular diffractive optical or optical properties, magnetic properties).
- Lacquer or metal layers which cause an optical effect (color, color effects, gloss, reflection) or have functional properties (adhesion, wetting of the UV lacquer layer, electrical conductivity, optically active, in particular diffractive optical or optical properties, magnetic properties).
- the UV varnish can be applied by known application methods, e.g. Roller application, printing (gravure, flexo, offset or digital printing), casting or spraying, using slot die coating or curtain coating done.
- application methods e.g. Roller application, printing (gravure, flexo, offset or digital printing), casting or spraying, using slot die coating or curtain coating done.
- the selection of the application method is basically irrelevant, but the person skilled in the art will prefer to choose such a method which produces a layer on the substrate with as homogeneous a thickness as possible and as smooth a surface as possible.
- an interesting, visually appealing contrast can also be created by the characteristic surface structure of the respective coating application in conjunction with the partial matting.
- the UV varnish is present as a mixture of monomers or oligomers with one or more photoinitiators and optionally other ingredients such as pigments, additives or solvents.
- all radiation-curable UV coating compositions are suitable, but in particular the compositions consisting of DE 44 39 350 are known and react to the curing with excimer radiation with the formation of a micro-rough or -folded surface.
- the thickness of the applied lacquer layer is usually between 1 and 1000 microns.
- the layer thickness is usually in the range of 1 - 20 microns, in plates whose thickness is usually much greater, the layer thickness is more in the range of 50 - 1000 microns.
- the coated carrier substrate is then optionally pre-dried in a thermal dryer, whereby any volatile components present in the layer, such as e.g. Solvent, to be removed.
- a thermal dryer whereby any volatile components present in the layer, such as e.g. Solvent, to be removed.
- the coated carrier substrate is supplied to the excimer irradiation.
- the excimer radiator is oriented transversely to the transport direction of the carrier substrate and positioned relative to the web so that the generated UV radiation strikes the coated side of the carrier substrate and initiates a crosslinking reaction on the surface of the UV varnish there.
- the actual excimer radiator ie the lamp which generates the excimer radiation, is thereby positioned within a circumferential template which rotates around the radiator.
- the length of the lamp is sized to be wider than the support substrate to ensure homogeneous radiation performance across the entire width.
- the stencil has UV-transmissive and UV-opaque areas corresponding to the desired matted structures.
- such a template may be designed like a rotary screen printing stencil, ie consist of a cylindrical net-like or fabric-like framework that is partially sealed with a UV-impermeable layer, for example a plastic layer, and thus is no longer transparent at these sealed locations. At locations where the mesh or fabric is not coated, the template is at least partially transparent.
- the permeability of the template is the diameter of the mesh or fabric fibers and the mesh size of the network or tissue and can also be influenced by suitable selection of the materials.
- the production of such a template is carried out in the same process that is used for the production of rotary printing screens.
- the structures that can be created with it are identical to those that can also be generated by rotary screen printing.
- the net or fabric-like framework can also consist of metal.
- the template is formed from a metal cylinder having open recesses in which the excimer radiation can pass through the template completely unhindered.
- the recesses can thereby be mechanically, i. be introduced by a drilling or milling process or by laser cutting in the cylinder.
- the template is made of a material such as quartz, MgF 2 , or the like that is transparent to the wavelength of the excimer radiation.
- a cylinder is made of this material and areas are masked on its surface so that excimer radiation no longer penetrates these areas.
- the surface of the cylinder with a metal layer, which consists for example of chromium or aluminum and is thick enough to prevent the excimer radiation, coated.
- the coating can be applied by a vacuum coating method or by electroplating.
- the structuring takes place, for example, with a photolithographic process or with the aid of a laser by ablation.
- an absorber layer is applied only partially to the areas to be masked, for example by printing or by means of adhesively bonded, impermeable to the excimer radiation, covers. Also at In this embodiment, any structures can be produced, since the cylinder itself constitutes a continuous supporting structure.
- the template is driven by a motor directly or by means of a toothed or V-belt or gear.
- the rotational speed of the template is adjusted so that the tangential velocity of the cylinder in the plane of the masking layer is identical to the transport speed of the substrate. This ensures that no relative movement between the template and the carrier substrate is formed and the structures of the template are sharp-edged imaged on the surface of the paint.
- the distance between the stencil and the lacquer surface is chosen as small as possible, but a small gap must remain, since otherwise the danger of adhesion of the lacquer to the stencil exists.
- the distance is in the range of 0.1 to 10 mm.
- a film in the region of the template is guided over a counter roller, whose distance from the template can be precisely controlled.
- the film is thereby stabilized such that the distance to the radiator can be kept constant within a small tolerance.
- the template itself consists of an endless, web-shaped fabric tape which, like one of the templates described above, consists of a reticulated or web-shaped substrate which is partially coated with an excimer-impermeable material.
- the endless belt is guided over several guide rollers around the excimer radiator, wherein the web speed is selected to be identical to the transport speed of the carrier substrate.
- a net or tissue-shaped substrate and a metal foil can be used with openings.
- a micro-rough surface forms locally at the exposed areas.
- this surface structure produces a matt optical impression because the surface diffuses light diffusely.
- the micro-cladding and the resulting surface relief create a haptic that differs significantly from a smooth varnish surface.
- the paint surface is not modified, i.
- the surface is in the same condition as after applying the paint.
- the paint is applied so that the surface has a very high smoothness and thus a very high gloss. The contrast between the frosted and glossy areas is then particularly high.
- the wavelength of the excimer radiation is in the range of 110-300 nm, but mostly at 172 nm.
- the entire unit consisting of excimer lamp and template and possibly a guide roller for adjusting the distance is located in an enclosure within which a controlled, inert atmosphere, for example, by continuous purging with argon, nitrogen or other noble gas, can be adjusted.
- a controlled, inert atmosphere for example, by continuous purging with argon, nitrogen or other noble gas
- the inerting is imperative in order on the one hand to avoid absorption of the excimer radiation by components of the ambient air (CO 2 , water vapor) and, on the other hand, to prevent the oxygen inhibition of the crosslinking reaction at the paint surface.
- the oxygen-inhibition causes the radicals or chain parts of the UV varnish to be terminated by incorporation of oxygen and thus can not polymerize further. This effect mainly occurs with thin layers (less than 1 ⁇ m) and is therefore particularly relevant for the surface hardening of paint layers.
- the partially exposed carrier substrate now passes to a second UV emitter, which, however, operates with radiation of a longer wavelength, typically in the range of 300-500 nm. This ensures that the surface relief produced in the matte areas by the excimer treatment is frozen, so to speak is fixed and the entire coating layer in all areas simultaneously cured or fully crosslinked. If necessary, an enclosure for inerting with noble gases or nitrogen may also be provided around the second UV radiator.
- UV coating layers with matt and glossy areas are produced in a single operation, wherein the carrier substrate on the entire surface an excellent scratch resistance and a substantially flat surface, so no height difference between smooth and frosted areas has.
- the substrates produced in this way with a partially matted UV lacquer layer can be used as decorative films or sheets or for decorative surface finishing for furniture surfaces, household appliances, in interior design, the interior of motor vehicles and the like.
- carrier substrate used, they can be applied to surfaces of different types, for example plastic, wood, composite material or metal substrates, or used as piece goods themselves.
- the biggest advantage of the method described here is that it runs continuously and does not have to stop the transport of the carrier substrate during the exposure. This enables an efficient, cost-effective and large-volume production of decorative functional parts.

Alle diese Verfahren stellen vollflächige, mattierte Lackschichten bereit. Eine partielle Mattierung kann höchstens dann erzielt werden, wenn bereits der UV-Lack partiell aufgebracht wird, wobei dann an den nicht bedruckten Stellen das Trägersubstrat zum Vorschein kommt. Das bedeutet jedoch auch, dass an den unbedruckten Stellen die Kratzfestigkeit der Folienoberfläche deutlich niedriger als die der UV-Lackschicht ist.All of these methods provide full-surface, frosted lacquer coatings. A partial matting can be achieved at most when already the UV coating is partially applied, in which case the carrier substrate appears at the non-printed areas. However, this also means that at the unprinted areas, the scratch resistance of the film surface is significantly lower than that of the UV lacquer layer.
Alternativ kann die Trägerfolie zunächst vollflächig mit einer kratzfesten UV-Lackschicht beschichtet und anschließend partiell mit einer matten UV-Lackschicht beschichtet werden. Dabei sind jedoch zwei Arbeitsschritte notwendig und es entsteht ein Dickenunterschied zwischen den mattierten und glänzenden Stellen.Alternatively, the carrier film can first be coated over the whole area with a scratch-resistant UV lacquer layer and then partially coated with a matt UV lacquer layer. However, two steps are necessary and there is a difference in thickness between the frosted and glossy spots.
Aufgabe der Erfindung war es, ein Verfahren bereitzustellen, bei dem keine vollflächige, sondern eine partielle Mattierung von UV-Lackschichten in einem einzelnen Arbeitsgang möglich ist.The object of the invention was to provide a method in which no full-surface, but a partial matting of UV lacquer layers in a single operation is possible.
Gegenstand der Erfindung ist daher ein Verfahren zur partiellen Mattierung von UV-Lackschichten gemäß Anspruch 1.The invention therefore provides a process for the partial matting of UV lacquer layers according to
Zur Durchführung des Verfahrens wird zunächst auf ein Trägersubstrat eine UV-Lackschicht aufgebracht.To carry out the method, a UV lacquer layer is first applied to a carrier substrate.
Als Trägersubstrate kommen beispielsweise Trägerfolien vorzugsweise flexible Kunststofffolien, beispielsweise aus PI, PP, MOPP, PE, PPS, PEEK, PEK, PEI, PSU, PAEK, LCP, PEN, PBT, PET, PA, PC, COC, POM, ABS, PVC, PTFE, ETFE (Ethylentetrafluorethylen), PFA (Tetrafluorethylen-Perfluorpropylvinylether-Fluorcopolymer), MFA (Tetrafluor-methylen-Perfluorpropylvinylether-Fluorcopolymer), PTFE (Polytetra-fluorethylen), PVF (Polyvinylfluorid), PVDF (Polyvinylidenfluorid), und EFEP (Ethylen-Tetrafluorethylen-Hexafluorpropylen-Fluorterpolymer) in Frage.As carrier substrates, for example carrier films are preferably flexible plastic films, for example of PI, PP, MOPP, PE, PPS, PEEK, PEK, PEI, PSU, PAEK, LCP, PEN, PBT, PET, PA, PC, COC, POM, ABS, PVC , PTFE, ETFE (ethylene tetrafluoroethylene), PFA (tetrafluoroethylene-perfluoropropyl vinyl ether fluorocopolymer), MFA (tetrafluoromethylene-perfluoropropyl vinyl ether fluorocopolymer), PTFE (polytetrafluoroethylene), PVF (polyvinyl fluoride), PVDF (polyvinylidene fluoride), and EFEP (ethylene oxide). Tetrafluoroethylene-hexafluoropropylene fluoroterpolymer).
Die Trägerfolien weisen vorzugsweise eine Dicke von 5 - 700 µm, bevorzugt 5 - 200 µm, besonders bevorzugt 5 - 50 µm auf.The carrier films preferably have a thickness of 5 to 700 .mu.m, preferably 5 to 200 .mu.m, particularly preferably 5 to 50 .mu.m.
Ferner können als Trägersubstrat auch Metallfolien, beispielsweise Al-, Cu-, Sn-, Ni-, Fe- oder Edelstahlfolien mit einer Dicke von 5 - 200 µm, vorzugsweise 10 bis 80 µm, besonders bevorzugt 20 - 50 µm dienen. Die Folien können auch oberflächenbehandelt, beschichtet oder kaschiert beispielsweise mit Kunststoffen oder lackiert sein.Furthermore, metal foils, for example Al, Cu, Sn, Ni, Fe or stainless steel foils having a thickness of 5-200 μm, preferably 10 to 80 μm, particularly preferably 20-50 μm, may also serve as the carrier substrate. The films can also be surface-treated, coated or laminated, for example, with plastics or painted.
Ferner können als Trägersubstrate auch zellstofffreies oder zellstoffhaltiges Papier, thermoaktivierbares Papier oder Verbunde mit Papier, beispielsweise Verbunde mit Kunststoffen mit einem Flächengewicht von 20 - 500 g/m2, vorzugsweise 40 - 200 g/m2. verwendet werden.Further, as carrier substrates and pulp-free or cellulose-containing paper, thermally activated paper or composites with paper, such as composites with plastics having a basis weight of 20 - 500 g / m 2 , preferably 40 - 200 g / m 2 . be used.
Ferner können als Trägersubstrate Gewebe oder Vliese, wie Endlosfaservliese, Stapelfaservliese und dergleichen, die gegebenenfalls vernadelt oder kalandriert sein können, verwendet werden. Vorzugsweise bestehen solche Gewebe oder Vliese aus Kunststoffen, wie PP, PET, PA, PPS und dergleichen, es können aber auch Gewebe oder Vliese aus natürlichen, gegebenenfalls behandelten Fasern, wie Viskosefasern eingesetzt werden. Die eingesetzten Vliese oder Gewebe weisen ein Flächengewicht von etwa 20 g/m2 bis 500 g/m2 auf. Gegebenenfalls müssen die Vliese oder Gewebe oberflächenbehandelt werden.Furthermore, woven or nonwovens, such as continuous fiber webs, staple fiber webs and the like, which may optionally be needled or calendered, can be used as carrier substrates. Preferably such fabrics or webs of plastics, such as PP, PET, PA, PPS and the like, but it can also be woven or nonwovens of natural, optionally treated fibers, such as viscose fibers are used. The nonwovens or fabrics used have a weight per unit area of about 20 g / m 2 to 500 g / m 2 . If necessary, the nonwovens or fabrics must be surface-treated.
Alle Trägersubstrate können als bahnförmige Substrate oder als Stückgut vorliegen.All carrier substrates can be present as web-shaped substrates or as piece goods.
Das Stückgut kann beispielsweise in Form von Platten, Fliesen oder sonstiger Formate aus gegebenenfalls beschichtetem Holz, Kunststoff, Metall, Keramik und dergleichen beschaffen sein. Die Dicke dieser Substrate beträgt in der Regel einige mm oder cm.The cargo may be, for example in the form of plates, tiles or other formats of optionally coated wood, plastic, metal, ceramics and the like. The thickness of these substrates is usually a few mm or cm.
Auf dem Trägersubstrat können bereits erste Schichten aufgebracht sein, z.B. Lack- oder Metallschichten, die einen optischen Effekt bewirken (Farbe, Farbeffekte, Glanz, Reflexion) oder funktionelle Eigenschaften haben (Haftung, Benetzung der UV-Lackschicht, elektrische Leitfähigkeit, optisch aktive, insbesondere beugungsoptisch aktive oder optische Eigenschaften, magnetische Eigenschaften).First layers may already be applied to the carrier substrate, e.g. Lacquer or metal layers which cause an optical effect (color, color effects, gloss, reflection) or have functional properties (adhesion, wetting of the UV lacquer layer, electrical conductivity, optically active, in particular diffractive optical or optical properties, magnetic properties).
Der UV-Lack kann über bekannte Auftragsverfahren, wie z.B. Walzenauftragsverfahren, Druck- (Tiefdruck-, Flexo-, Offset- oder Digitaldruckverfahren), Gieß- oder Sprühverfahren, über Schlitzdüsenbeschichtung oder Curtain Coating erfolgen. Die Auswahl des Auftragsverfahrens ist grundsätzlich unerheblich, der Fachmann wird bevorzugt jedoch ein solches Verfahren wählen, das auf dem Substrat eine Schicht mit möglichst homogener Dicke und möglichst glatter Oberfläche erzeugt. Jedoch kann auch durch die charakteristische Oberflächenstruktur des jeweiligen Lackauftrags im Zusammenspiel mit der partiellen Mattierung ein interessanter, optisch ansprechender Kontrast entstehen.The UV varnish can be applied by known application methods, e.g. Roller application, printing (gravure, flexo, offset or digital printing), casting or spraying, using slot die coating or curtain coating done. The selection of the application method is basically irrelevant, but the person skilled in the art will prefer to choose such a method which produces a layer on the substrate with as homogeneous a thickness as possible and as smooth a surface as possible. However, an interesting, visually appealing contrast can also be created by the characteristic surface structure of the respective coating application in conjunction with the partial matting.
Der UV-Lack liegt dabei als Gemisch von Monomeren bzw. Oligomeren mit einem oder mehreren Photoinitiatoren und ggf. weiteren Inhaltsstoffen wie Pigmenten, Additiven oder Lösungsmitteln vor.The UV varnish is present as a mixture of monomers or oligomers with one or more photoinitiators and optionally other ingredients such as pigments, additives or solvents.
Grundsätzlich sind alle strahlungshärtbaren UV-Lackzusammensetzungen geeignet, insbesondere jedoch die Zusammensetzungen, die aus
Die Dicke der aufgetragenen Lackschicht beträgt üblicherweise zwischen 1 und 1000 µm. Bei Foliensubstraten liegt die Schichtdicke üblicherweise im Bereich von 1 - 20 µm, bei Platten, deren Dicke in der Regel deutlich größer ist, liegt die Schichtdicke eher im Bereich von 50 - 1000 µm.The thickness of the applied lacquer layer is usually between 1 and 1000 microns. For film substrates, the layer thickness is usually in the range of 1 - 20 microns, in plates whose thickness is usually much greater, the layer thickness is more in the range of 50 - 1000 microns.
Das beschichtete Trägersubstrat wird anschließend gegebenenfalls in einem thermischen Trockner bzw. Umlufttrockner vorgetrocknet, wodurch auch eventuell in der Schicht vorhandene flüchtige Komponenten, wie z.B. Lösemittel, entfernt werden.The coated carrier substrate is then optionally pre-dried in a thermal dryer, whereby any volatile components present in the layer, such as e.g. Solvent, to be removed.
Danach wird das beschichtete Trägersubstrat der Excimer-Bestrahlung zugeführt. Der Excimer-Strahler ist quer zur Transportrichtung des Trägersubstrats orientiert und relativ zur Bahn so positioniert, dass die erzeugte UV-Strahlung auf die beschichtete Seite des Trägersubstrats trifft und dort eine Vernetzungsreaktion an der Oberfläche des UV-Lacks initiiert.Thereafter, the coated carrier substrate is supplied to the excimer irradiation. The excimer radiator is oriented transversely to the transport direction of the carrier substrate and positioned relative to the web so that the generated UV radiation strikes the coated side of the carrier substrate and initiates a crosslinking reaction on the surface of the UV varnish there.
Der eigentliche Excimer-Strahler, also die Lampe, die die Excimer-Strahlung erzeugt, wird dabei innerhalb einer umlaufenden Schablone positioniert, die um den Strahler rotiert. Die Länge der Lampe ist so bemessen, dass sie breiter als das Trägersubstrat ist, um eine homogene Strahlungsleistung über die gesamte Breite zu gewährleisten. Die Schablone weist UV-durchlässige und UV-undurchlässige Bereiche entsprechend den gewünschten Strukturen, die mattiert erscheinen sollen, auf.The actual excimer radiator, ie the lamp which generates the excimer radiation, is thereby positioned within a circumferential template which rotates around the radiator. The length of the lamp is sized to be wider than the support substrate to ensure homogeneous radiation performance across the entire width. The stencil has UV-transmissive and UV-opaque areas corresponding to the desired matted structures.
Eine solche Schablone kann in einer Ausführungsform wie eine Rotationssiebdruckschablone gestaltet sein, d.h. aus einem zylindrischen netz- oder gewebeartigen Gerüst bestehen, das partiell mit einer UV-undurchlässigen Schicht, beispielsweise einer Kunststoffschicht, versiegelt ist und somit an diesen versiegelten Stellen nicht mehr transparent ist. An den Stellen, an denen das Netz oder Gewebe nicht beschichtet ist, ist die Schablone zumindest teilweise transparent. Die Durchlässigkeit der Schablone wird dabei vom Durchmesser der Netz- bzw. Gewebefasern und der Maschenweite des Netzes bzw. Gewebes bestimmt und kann durch geeignete Auswahl der Materialien auch beeinflusst werden. Die Herstellung einer solchen Schablone erfolgt in demselben Verfahren, das zur Herstellung von Rotationsdrucksieben eingesetzt wird. Die Strukturen, die damit erzeugt werden können, sind identisch mit solchen, die auch mittels Rotationssiebdruck generiert werden können. Das netz- oder gewebeartige Gerüst kann dabei auch aus Metall bestehen.In one embodiment, such a template may be designed like a rotary screen printing stencil, ie consist of a cylindrical net-like or fabric-like framework that is partially sealed with a UV-impermeable layer, for example a plastic layer, and thus is no longer transparent at these sealed locations. At locations where the mesh or fabric is not coated, the template is at least partially transparent. The permeability of the template is the diameter of the mesh or fabric fibers and the mesh size of the network or tissue and can also be influenced by suitable selection of the materials. The production of such a template is carried out in the same process that is used for the production of rotary printing screens. The structures that can be created with it are identical to those that can also be generated by rotary screen printing. The net or fabric-like framework can also consist of metal.
In einer weiteren Ausführungsform ist die Schablone aus einem Metallzylinder geformt, der offene Aussparungen aufweist, in denen die Excimer-Strahlung die Schablone völlig ungehindert passieren kann. Die Aussparungen können dabei mechanisch, d.h. durch einen Bohr- oder Fräsprozess oder mittels Laserschneiden in den Zylinder eingebracht werden. Hinsichtlich der Strukturen, die mit einer solchen Schablone erzeugt werden können, bestehen jedoch Einschränkungen, da die Schablone nach der Bearbeitung noch eine hinreichende mechanische Stabilität aufweisen muss, um den bei der Montage bzw. bei der Rotation auftretenden Kräften standzuhalten.In another embodiment, the template is formed from a metal cylinder having open recesses in which the excimer radiation can pass through the template completely unhindered. The recesses can thereby be mechanically, i. be introduced by a drilling or milling process or by laser cutting in the cylinder. With regard to the structures that can be produced with such a template, however, there are restrictions, since the template still has to have sufficient mechanical stability after processing in order to withstand the forces occurring during assembly or during rotation.
Eine weitere Ausführungsform kann dermaßen beschaffen sein, dass die Schablone aus einem Material, wie z.B. Quarz, MgF2, oder dergleichen, besteht, das für die Wellenlänge der Excimer-Strahlung transparent ist. Aus diesem Material wird ein Zylinder hergestellt und auf dessen Oberfläche werden Bereiche maskiert, sodass an diesen Stellen keine Excimer-Strahlung mehr durchdringt. Dazu wird beispielsweise die Oberfläche des Zylinders mit einer Metallschicht, die z.B. aus Chrom oder Aluminium besteht und dick genug ist, um die Excimer-Strahlung nicht durchzulassen, beschichtet. Die Beschichtung kann mit einem Vakuumbeschichtungsverfahren oder galvanisch aufgebracht werden. Die Strukturierung erfolgt beispielsweise mit einem photolithographischen Verfahren oder mit Hilfe eines Lasers durch Ablation. Genauso ist es denkbar, dass eine Absorberschicht nur partiell an den zu maskierenden Stellen, z.B. durch Bedruckung oder mittels aufgeklebter, für die Excimer-Strahlung undurchlässigen, Abdeckungen aufgebracht wird. Auch bei dieser Ausführung können beliebige Strukturen erzeugt werden, da der Zylinder an sich eine durchgehende tragende Struktur darstellt.Another embodiment may be such that the template is made of a material such as quartz, MgF 2 , or the like that is transparent to the wavelength of the excimer radiation. A cylinder is made of this material and areas are masked on its surface so that excimer radiation no longer penetrates these areas. For this purpose, for example, the surface of the cylinder with a metal layer, which consists for example of chromium or aluminum and is thick enough to prevent the excimer radiation, coated. The coating can be applied by a vacuum coating method or by electroplating. The structuring takes place, for example, with a photolithographic process or with the aid of a laser by ablation. It is equally conceivable that an absorber layer is applied only partially to the areas to be masked, for example by printing or by means of adhesively bonded, impermeable to the excimer radiation, covers. Also at In this embodiment, any structures can be produced, since the cylinder itself constitutes a continuous supporting structure.
Die Schablone wird über einen Motor direkt oder mittels eines Zahn- oder Keilriemens oder Zahnrades angetrieben. Die Rotationsgeschwindigkeit der Schablone wird dabei so eingestellt, dass die Tangentialgeschwindigkeit des Zylinders in der Ebene der Maskierungsschicht identisch mit der Transportgeschwindigkeit des Substrats ist. Damit wird gewährleistet, dass keine Relativbewegung zwischen der Schablone und dem Trägersubstrat entsteht und die Strukturen der Schablone scharfkantig auf der Oberfläche des Lacks abgebildet werden.The template is driven by a motor directly or by means of a toothed or V-belt or gear. The rotational speed of the template is adjusted so that the tangential velocity of the cylinder in the plane of the masking layer is identical to the transport speed of the substrate. This ensures that no relative movement between the template and the carrier substrate is formed and the structures of the template are sharp-edged imaged on the surface of the paint.
Zur Erzielung einer präzisen Kantenschärfe wird der Abstand zwischen Schablone und Lackoberfläche möglichst gering gewählt, es muss jedoch ein geringer Spalt verbleiben, da ansonsten die Gefahr der Anhaftung des Lackes auf der Schablone besteht. Der Abstand liegt im Bereich von 0,1 bis 10 mm.To achieve a precise edge sharpness, the distance between the stencil and the lacquer surface is chosen as small as possible, but a small gap must remain, since otherwise the danger of adhesion of the lacquer to the stencil exists. The distance is in the range of 0.1 to 10 mm.
Eine Veränderung dieses Abstands würde unweigerlich zu Schwankungen in der Kantenschärfe führen, weshalb in einer bevorzugten Ausführungsform eine Folie im Bereich der Schablone über eine Gegenwalze geführt wird, deren Abstand zur Schablone genau geregelt werden kann. Die Folie wird dadurch derart stabilisiert, dass der Abstand zum Strahler innerhalb einer geringen Toleranz konstant gehalten werden kann.A change in this distance would inevitably lead to fluctuations in the edge sharpness, which is why, in a preferred embodiment, a film in the region of the template is guided over a counter roller, whose distance from the template can be precisely controlled. The film is thereby stabilized such that the distance to the radiator can be kept constant within a small tolerance.
In einer weiteren Ausführungsform besteht die Schablone selbst aus einem endlosen, bahnförmigen Gewebeband, das wie eine der oben beschriebenen Schablonen aus einem netz- oder gewebeförmigen Substrat besteht, das partiell mit einem Excimer-undurchlässigen Material beschichtet ist. Das Endlosband wird über mehrere Leitrollen rund um den Excimer-Strahler geführt, wobei die Bahngeschwindigkeit identisch mit der Transportgeschwindigkeit des Trägersubstrats gewählt wird. Anstatt eines netz- oder gewebeförmigen Substrats kann auch eine Metallfolie mit Durchbrechungen verwendet werden.In another embodiment, the template itself consists of an endless, web-shaped fabric tape which, like one of the templates described above, consists of a reticulated or web-shaped substrate which is partially coated with an excimer-impermeable material. The endless belt is guided over several guide rollers around the excimer radiator, wherein the web speed is selected to be identical to the transport speed of the carrier substrate. Instead of a net or tissue-shaped substrate and a metal foil can be used with openings.
Durch die Bestrahlung der Lackoberfläche mit der Excimer-Strahlung bildet sich lokal an den belichteten Stellen eine mikroraue Oberfläche aus. Diese Oberflächenstruktur erzeugt nun einerseits einen matten optischen Eindruck, da die Oberfläche Licht diffus streut. Andererseits wird durch die Mikrofaltung und das dadurch entstehende Oberflächenrelief eine Haptik erzeugt, die sich von einer glatten Lackoberfläche deutlich unterscheidet. In den nicht belichteten Bereichen wird die Lackoberfläche nicht modifiziert, d.h. die Oberfläche ist in demselben Zustand wie nach dem Auftrag des Lacks. Bevorzugt wird der Lack so aufgetragen, dass die Oberfläche eine sehr hohe Glätte und somit einen sehr hohen Glanz aufweist. Der Kontrast zwischen den mattierten und glänzenden Bereichen ist dann besonders hoch.By irradiating the paint surface with the excimer radiation, a micro-rough surface forms locally at the exposed areas. On the one hand, this surface structure produces a matt optical impression because the surface diffuses light diffusely. On the other hand, the micro-cladding and the resulting surface relief create a haptic that differs significantly from a smooth varnish surface. In the unexposed areas, the paint surface is not modified, i. The surface is in the same condition as after applying the paint. Preferably, the paint is applied so that the surface has a very high smoothness and thus a very high gloss. The contrast between the frosted and glossy areas is then particularly high.
Die Wellenlänge der Excimer-Strahlung liegt im Bereich von 110 - 300 nm, meist jedoch bei 172 nm.The wavelength of the excimer radiation is in the range of 110-300 nm, but mostly at 172 nm.
Aufgrund der geringen Eindringtiefe der Excimer-Strahlung in die Lackschicht wird diese nur an der Oberfläche gehärtet, also in den ersten etwa 10 nm bis 1 µm. Die restliche Lackschicht unter der gehärteten Oberfläche verbleibt noch in flüssigem bzw. viskosem Zustand.Due to the low penetration depth of the excimer radiation in the lacquer layer, this is cured only on the surface, ie in the first about 10 nm to 1 micron. The remaining lacquer layer under the hardened surface still remains in a liquid or viscous state.
Die gesamte Einheit bestehend aus Excimer-Lampe und Schablone sowie ggf. einer Leitrolle zur Einstellung des Abstands befindet sich in einer Einhausung, innerhalb derer eine kontrollierte, inerte Atmosphäre, beispielsweise durch kontinuierliches Spülen mit Argon, Stickstoff oder einem anderen Edelgas, eingestellt werden kann. Die Inertisierung ist zwingend notwendig, um einerseits eine Absorption der Excimer-Strahlung durch Komponenten der Umgebungsluft (CO2, Wasserdampf) zu vermeiden und andererseits die Sauerstoff-Inhibierung der Vernetzungsreaktion an der Lackoberfläche zu unterbinden. Die Sauerstoff-Inhibierung bewirkt, dass die Radikale bzw. Kettenteile des UV-Lacks durch Einbau von Sauerstoff terminiert werden und so nicht weiter polymerisieren können. Dieser Effekt tritt vor allem bei dünnen Schichten (unter 1 µm) auf und ist daher insbesondere bei der oberflächlichen Härtung von Lackschichten relevant.The entire unit consisting of excimer lamp and template and possibly a guide roller for adjusting the distance is located in an enclosure within which a controlled, inert atmosphere, for example, by continuous purging with argon, nitrogen or other noble gas, can be adjusted. The inerting is imperative in order on the one hand to avoid absorption of the excimer radiation by components of the ambient air (CO 2 , water vapor) and, on the other hand, to prevent the oxygen inhibition of the crosslinking reaction at the paint surface. The oxygen-inhibition causes the radicals or chain parts of the UV varnish to be terminated by incorporation of oxygen and thus can not polymerize further. This effect mainly occurs with thin layers (less than 1 μm) and is therefore particularly relevant for the surface hardening of paint layers.
Das teilweise belichtete Trägersubstrat gelangt nun zu einem zweiten UV-Strahler, der jedoch mit Strahlung einer längeren Wellenlänge arbeitet, typischerweise im Bereich von 300 - 500 nm. Dadurch wird erreicht, dass das in den matten Bereichen durch die Excimerbehandlung erzeugte Oberflächenrelief sozusagen eingefroren und rasch fixiert wird und die gesamte Lackschicht in allen Bereichen gleichzeitig durchgehärtet bzw. vollständig vernetzt wird. Auch um den zweiten UV-Strahler kann ggf. eine Einhausung zur Inertisierung mit Edelgasen oder Stickstoff vorgesehen sein.The partially exposed carrier substrate now passes to a second UV emitter, which, however, operates with radiation of a longer wavelength, typically in the range of 300-500 nm. This ensures that the surface relief produced in the matte areas by the excimer treatment is frozen, so to speak is fixed and the entire coating layer in all areas simultaneously cured or fully crosslinked. If necessary, an enclosure for inerting with noble gases or nitrogen may also be provided around the second UV radiator.
Dadurch werden in einem einzelnen Arbeitsgang UV-Lackschichten mit matten und glänzenden Bereichen hergestellt, wobei das Trägersubstrat auf der gesamten Fläche eine ausgezeichnete Kratzfestigkeit und eine im Wesentlichen ebene Oberfläche, also keinen Höhenunterschied zwischen glatten und mattierten Bereichen, aufweist.As a result, UV coating layers with matt and glossy areas are produced in a single operation, wherein the carrier substrate on the entire surface an excellent scratch resistance and a substantially flat surface, so no height difference between smooth and frosted areas has.
Die auf diese Weise hergestellten Substrate mit einer partiell mattierten UV-Lackschicht können als Dekorfolien oder -platten bzw. zur dekorativen Oberflächenveredelung für Möbeloberflächen, Haushaltsgeräte, in der Innenarchitektur, der Innenausstattung von Kraftfahrzeugen und dergleichen verwendet werden.The substrates produced in this way with a partially matted UV lacquer layer can be used as decorative films or sheets or for decorative surface finishing for furniture surfaces, household appliances, in interior design, the interior of motor vehicles and the like.
Sie können dabei je nach verwendetem Trägersubstrat auf Oberflächen unterschiedlicher Beschaffenheit, beispielsweise auf Kunststoff-, Holz-, Verbundmaterial- oder Metallträger aufgebracht werden, oder als Stückgut selbst verwendet werden.Depending on the carrier substrate used, they can be applied to surfaces of different types, for example plastic, wood, composite material or metal substrates, or used as piece goods themselves.
Der größte Vorteil des hier beschriebenen Verfahrens liegt darin, dass es kontinuierlich abläuft und der Transport des Trägersubstrats während der Belichtung nicht stoppen muss. Damit ist eine effiziente, kostengünstige und großvolumige Produktion von dekorativen Funktionsteilen möglich.The biggest advantage of the method described here is that it runs continuously and does not have to stop the transport of the carrier substrate during the exposure. This enables an efficient, cost-effective and large-volume production of decorative functional parts.
