Abstract
Vitrage feuilleté ayant une couche de polyvinylbutyral dans laquelle est intégré un tissu comportant une encre ultraviolet L’invention a trait à un vitrage feuilleté comprenant au moins une première et une seconde feuilles de verre collées au moyen d’une couche adhésive intercalaire de polyvinylbutyral (PVB), dans laquelle est intégré un tissu, caractérisé en ce que le tissu comporte une encre ultraviolet (UV) ; à un procédé de fabrication de ce vitrage feuilleté ; et à son application pour un véhicule, pour le bâtiment, le mobilier urbain, l’aménagement intérieur, ou l’électroménager. Laminated glazing having a layer of polyvinyl butyral in which is integrated a fabric comprising an ultraviolet ink The invention relates to laminated glazing comprising at least a first and a second pane of glass bonded by means of an interlayer adhesive layer of polyvinyl butyral (PVB), in which a fabric is integrated, characterized in that the fabric comprises a ultraviolet (UV) ink; to a method of manufacturing such laminated glazing; and its application for a vehicle, for the building, street furniture, interior design, or household appliances.
Description
L’invention est relative à un vitrage feuilleté lumineux, par exemple pour l’automobile (toit, pare-brise, lunette arrière, vitrage latéral) ou le bâtiment (veranda, façade). Le vitrage est soit à décor lumineux constitué d’un motif, soit sur toute sa surface. Le motif est le cas échéant uniquement décoratif, ou représente une marque de fabrique, un logo, ou encore délivre une information sur les caractéristiques techniques du vitrage feuilleté, ou une indication du cheminement dans les applications bâtiment, par exemple dans les aéroports, les gares, ou du nombre de personnes dans un bureau…The invention relates to luminous laminated glazing, for example for automobiles (roof, windshield, rear window, side glazing) or buildings (veranda, facade). The glazing is either with luminous decoration consisting of a pattern, or over its entire surface. The pattern is, where appropriate, purely decorative, or represents a trademark, a logo, or even delivers information on the technical characteristics of the laminated glazing, or an indication of the path in building applications, for example in airports, stations , or the number of people in an office…
Sont connus des vitrages feuilletés lumineux, notamment comme toits automobiles, dans lesquels des diodes électroluminescentes (en anglais light-emitting diodes, abrégé en LEDs) sont intégrées, mais cette technique offre des possibilités de décor, esthétiques et d’informations délivrées nécessairement limitées.Luminous laminated glazing is known, in particular as automobile roofs, in which light-emitting diodes (abbreviated as LEDs) are integrated, but this technique offers necessarily limited decorative, aesthetic and information delivery possibilities.
Les inventeurs ont recherché à élargir les possibilités d’aspects esthétiques et d’informations délivrables par un vitrage feuilleté lumineux. Ils ont atteint cet objectif par l’invention qui, en conséquence, a pour objet un vitrage feuilleté comprenant au moins une première et une seconde feuilles de verre collées au moyen d’une couche adhésive intercalaire de polyvinylbutyral (PVB), dans laquelle est intégré un tissu, caractérisé en ce que le tissu comporte une encre ultraviolet (UV).The inventors have sought to broaden the possibilities of aesthetic aspects and information delivered by luminous laminated glazing. They have achieved this objective by the invention which, consequently, relates to a laminated glazing comprising at least a first and a second glass sheets bonded by means of an interlayer adhesive layer of polyvinyl butyral (PVB), in which is integrated a fabric, characterized in that the fabric comprises an ultraviolet (UV) ink.
Les feuilles de verre sont en verre minéral tel que flotté, sodocalcique, aluminosilicate, borosilicate, …, éventuellement trempé thermiquement, renforcé chimiquement. Une encre UV est une encre qui s’illumine sous l’éclairage d’une lampe produisant un rayonnement ultraviolet.The glass sheets are made of mineral glass such as float, soda-lime, aluminosilicate, borosilicate, etc., possibly thermally tempered, chemically reinforced. UV ink is ink that glows when illuminated by a lamp that produces ultraviolet radiation.
Le vitrage feuilleté comprend au moins une première et une seconde feuilles de verre, c’est-à-dire qu’on entend ne pas exclure de l’invention toute configuration de feuilleté à plus de deux feuilles de verre, deux telles feuilles de verre voisines étant collées par l’intermédiaire d’une couche de PVB.The laminated glazing comprises at least a first and a second sheet of glass, that is to say that it is not intended to exclude from the invention any configuration of laminate with more than two sheets of glass, two such sheets of glass neighbors being bonded via a layer of PVB.
Dans une variante conforme à l’invention, des fibres optiques sont intégrées dans la couche adhésive intercalaire. En reliant certaines fibres optiques à une illumination d’une certaine couleur, éventuellement d’autres fibres optiques à une illumination d’une autre couleur, on élargit considérablement l’offre d’effets esthétiques.In a variant in accordance with the invention, optical fibers are integrated into the intermediate adhesive layer. By connecting certain optical fibers to an illumination of a certain color, possibly other optical fibers to an illumination of another color, the offer of aesthetic effects is considerably widened.
Le tissu peut alors comprendre lui-même des fibres optiques, soit intégrées dans le tissu dont une partie au moins des fils constitutifs sont des fibres optiques, soit solidarisées par collage ou autre procédé à la surface du tissu.The fabric can then itself comprise optical fibers, either integrated into the fabric, of which at least some of the constituent yarns are optical fibers, or secured by gluing or another process to the surface of the fabric.
Dans une réalisation avantageuse de l’invention, l’une desdites première et seconde feuilles de verre porte une couche ou un empilement de couches fonctionnel(le). Il peut s’agir d’une couche mince (de quelques nanomètres à quelques dizaines de nanomètres d’épaisseur) ou un empilement de couches minces, tel(le) que produit(e) par pulvérisation cathodique assistée par champ magnétique (magnétron) sous pression réduite, par exemple d’un empilement de contrôle thermique tel qu’antisolaire ou bas-émissif. Peut être citée d’autre part une couche d’épaisseur jusqu’à quelques microns telle que produite par un dépôt par voie liquide, sol-gel, dépôt chimique en phase vapeur (en anglais chemical vapour deposition, abrégé en CVD), par exemple une couche hydrophobe, hydrophile, colorée, autonettoyante photocatalytique (TiO2anatase)…In an advantageous embodiment of the invention, one of said first and second glass sheets bears a functional layer or stack of layers. It may be a thin layer (from a few nanometers to a few tens of nanometers thick) or a stack of thin layers, such as produced by magnetic field assisted sputtering (magnetron) under reduced pressure, for example of a thermal control stack such as antisolar or low-emissivity. Mention may be made, on the other hand, of a layer with a thickness of up to a few microns such as produced by a liquid deposition, sol-gel, chemical vapor deposition (in English chemical vapor deposition, abbreviated as CVD), for example a hydrophobic, hydrophilic, coloured, self-cleaning photocatalytic layer (TiO 2 anatase)…
L’autre desdites première et seconde feuilles de verre porte alors avantageusement un émail tel que noir, notamment en bande périphérique pour cacher le cordon de colle du vitrage à son environnement de montage (par exemple une carrosserie automobile). Cet émail peut être produit par un procédé d’impression comme la sérigraphie.The other of said first and second sheets of glass then advantageously bears an enamel such as black, in particular in a peripheral band to hide the bead of glue of the glazing from its mounting environment (for example an automobile body). This enamel can be produced by a printing process such as screen printing.
Un autre objet de l’invention consiste en un procédé de fabrication du vitrage feuilleté décrit précédemment, caractérisé en ce qu’un tissu comportant une encre UV est positionné entre deux couches de PVB, en ce que l’ensemble ainsi obtenu est positionné entre au moins une première et une seconde feuilles de verre, puis en ce que l’on effectue le feuilletage en soumettant ces constituants à une augmentation de la température et à une augmentation ou une diminution de la pression. Par le fait que les deux couches de PVB et le tissu placé entre elles sont positionnés entre au moins une première et une seconde feuilles de verre, on entend qu’une ou plusieurs autres feuilles de verre peuvent être assemblées à ces deux premières, étant entendu que chaque couple de feuilles de verre voisines dans l’assemblage comprend une couche de PVB intercalée assurant la cohésion de tout le vitrage feuilleté après le feuilletage.Another object of the invention consists of a method for manufacturing the laminated glazing described above, characterized in that a fabric comprising a UV ink is positioned between two layers of PVB, in that the assembly thus obtained is positioned between at at least a first and a second sheet of glass, then in that the lamination is carried out by subjecting these constituents to an increase in temperature and to an increase or decrease in pressure. By the fact that the two layers of PVB and the fabric placed between them are positioned between at least a first and a second sheet of glass, it is meant that one or more other sheets of glass can be assembled to these first two, it being understood that each pair of adjacent glass sheets in the assembly comprises an interposed layer of PVB ensuring the cohesion of all the laminated glazing after the lamination.
De préférence, le tissu comportant une encre UV est préalablement obtenu par impression avec une encre UV par sérigraphie, jet d’encre, tampographie, offset, flexographie ou autre procédé d’impression, ou dépôt d’une couche d’encre UV par tout procédé de dépôt par voie liquide tel qu’à la tournette (en anglais spin coating), par pulvérisation, rideau ou équivalent.Preferably, the fabric comprising a UV ink is obtained beforehand by printing with a UV ink by screen printing, inkjet, pad printing, offset, flexography or other printing process, or depositing a layer of UV ink by any liquid deposition process such as spin coating, spraying, curtain or equivalent.
L’invention a d’autre part pour objet l’application du vitrage feuilleté décrit ci-dessus pour un véhicule terrestre, automobile, ferroviaire, aquatique ou aérien, pour le bâtiment, le mobilier urbain, l’aménagement intérieur, ou l’électroménager, et en particulier comme toit automobile.The invention also relates to the application of the laminated glazing described above for a land, automobile, rail, water or air vehicle, for building, street furniture, interior fittings, or household appliances. , and in particular as a car roof.
L’invention est maintenant illustrée par l’exemple de réalisation suivant.The invention is now illustrated by the following exemplary embodiment.
ExempleExample
Différents échantillons de tissu sont imprimés avec une encre UV par toute technique appropriée. Avant cette impression, certains tissus comportent des motifs en relief ou texturation. L’impression d’encre UV est appliquée précisément sur certains de ces motifs, mais non sur d’autres restant vierges d’encre UV, et d’autre part, l’impression d’encre UV est appliquée à l’extérieur de ces motifs.Different fabric samples are printed with UV ink by any suitable technique. Prior to this printing, some fabrics feature raised or textured patterns. The UV ink printing is applied precisely on some of these patterns, but not on others remaining free of UV ink, and on the other hand, the UV ink printing is applied on the outside of these patterns.
Plusieurs de ces échantillons de tissu imprimé sont placés chacun entre deux feuilles de PVB de 0,38 mm d’épaisseur, puis l’ensemble ainsi obtenu est placé entre deux feuilles de verre transparent de 2,1 mm d’épaisseur commercialisé par la Société Saint-Gobain Glass sous la marque enregistrée Planiclear®.Several of these samples of printed fabric are each placed between two sheets of PVB 0.38 mm thick, then the assembly thus obtained is placed between two sheets of transparent glass 2.1 mm thick marketed by the Company Saint-Gobain Glass under the registered trademark Planiclear®.
La face orientée vers l’intérieur de la structure feuilletée de la première des deux feuilles de verre, destinée à être orientée vers l’extérieur d’une automobile en position de montage, porte un cadre d’émail noir en bande périphérique. La face orientée vers l’intérieur de la structure feuilletée de l’autre (seconde) feuille de verre, destinée à être orientée vers l’habitacle d’une automobile en position de montage, est revêtue d’un empilement de couches minces bas-émissif (en anglais low-e) ou anti-solaire comportant plusieurs couches minces d’argent, selon les échantillons.The inward-facing side of the laminated structure of the first of the two sheets of glass, intended to face outwards from an automobile in the assembly position, bears a black enamel frame in a peripheral band. The face oriented towards the inside of the laminated structure of the other (second) glass sheet, intended to be oriented towards the passenger compartment of an automobile in the assembly position, is coated with a stack of thin layers low- emissive (in English low-e) or anti-solar comprising several thin layers of silver, depending on the samples.
On effectue le feuilletage, en mettant en oeuvre un premier cycle en étuve comprenant une mise sous vide (diminution de la pression par rapport à l’atmosphérique), un chauffage et un maintien à 30 °C, un chauffage et un maintien à 120 °C, une diminution de la température à 75 °C et un arrêt du vide, puis un second cycle à l’autoclave comprenant une augmentation de la température à 140 °C, une augmentation et un maintien de la pression à 11,5 bar, une diminution de la température à 50 °C, et un retour à la pression atmosphérique. D’autres conditions de feuilletage sont possibles, de manière bien connue dans le domaine technique.The lamination is carried out, by implementing a first cycle in an oven comprising placing under vacuum (reduction of the pressure relative to atmospheric), heating and holding at 30° C., heating and holding at 120° C. C, a decrease in temperature to 75°C and a stoppage of the vacuum, then a second cycle in the autoclave comprising an increase in temperature to 140°C, an increase and maintenance of the pressure at 11.5 bar, a decrease in temperature to 50°C, and a return to atmospheric pressure. Other lamination conditions are possible, in a manner well known in the technical field.
On constate que le feuilletage n’a pas affecté les motifs en relief ou texturation des tissus, ni dans leur contour ou délimitation, ni dans leur aspect en relief.It can be seen that the lamination did not affect the relief patterns or texturing of the fabrics, neither in their contour or delimitation, nor in their relief appearance.
Puis on expose les échantillons de vitrages feuilletés à une illumination sous rayonnement ultraviolet. On observe que ceux des motifs en relief ou texturation des tissus qui sont imprimés avec l’encre UV s’illuminent selon les contours précis des motifs initiaux sur lesquels on est soigneusement repassé avec l’encre. On ne constate donc aucune migration de l’encre consécutive aux opérations de feuilletage.The laminated glazing samples are then exposed to illumination under ultraviolet radiation. It is observed that those of the patterns in relief or texturing of the fabrics which are printed with UV ink light up according to the precise contours of the initial patterns on which one is carefully ironed with the ink. There is therefore no ink migration resulting from lamination operations.
On observe également sur les impressions d’encre UV à l’extérieur des motifs en relief ou texturation du tissu, un maintien du motif imprimé initial, d’excellentes définition et résolution des motifs imprimés, compatibles avec l’impression d’un texte, tel que d’un texte d’informations ou consignes de sécurité.We also observe on the UV ink prints on the outside of the patterns in relief or texturing of the fabric, a maintenance of the initial printed pattern, excellent definition and resolution of the printed patterns, compatible with the printing of a text, such as an information text or safety instructions.
