Description
L’invention se situe dans le domaine technique de la transformation du verre plat et plus particulièrement celui des vitrages feuilletés et laqués.The invention lies in the technical field of processing flat glass and more particularly that of laminated and lacquered glazing.
Le produit est destiné au marché du bâtiment intérieur ainsi qu’au marché de l’ameublement.The product is intended for the interior building market as well as the furniture market.
Aujourd’hui sur le marché il existe du laqué – feuilleté. Ce produit est réalisé à partir d’un verre laqué sur lequel un primaire d’adhésion est appliqué (face laque). Le feuilletage polyvinylbutyral (PVB) est ensuite réalisé (la laque est en face intérieure du produit).Today there is lacquer - laminated on the market. This product is made from lacquered glass on which an adhesion primer is applied (lacquer side). Polyvinyl butyral (PVB) lamination is then carried out (the lacquer is on the inside of the product).
Le défaut de ce produit est que l’adhésion de la laque sur le PVB est très mauvaise d’où l’application obligatoire d’un primaire de type silane.The shortcoming of this product is that the adhesion of the lacquer to the PVB is very poor hence the mandatory application of a silane-type primer.
Ce produit n’est disponible qu’en pleine largeur float PLF et demie largeur float DLF donc des formats très limités qui par leur nature seront forcément retransformés par la suite. Les couleurs disponibles sont très limitées.This product is only available in full width float PLF and half width float DLF therefore very limited formats which by their nature will necessarily be retransformed later. The colors available are very limited.
Dans certains produits laqués feuilletés, dans lesquels la face laque est à l’intérieur de la structure feuilletée, le PVB peut être remplacé par l’éthylène – acétate de vinyle (EVA); l’adhésion est aléatoire dans la durée.In some laminated lacquer products, where the lacquer face is inside the laminate structure, PVB can be replaced by ethylene vinyl acetate (EVA); membership is random over time.
Les inventeurs ont cherché à résoudre ces problèmes par l’invention qui, en conséquence, a pour objet un procédé de fabrication d’un vitrage feuilleté laqué comprenant au moins deux feuilles de verre minéral tel que sodocalcique, aluminosilicate, borosilicate, deux telles feuilles consécutives étant collées l’une à l’autre par l’intermédiaire d’une couche adhésive intercalaire telle qu’en polyvinylbutyral (PVB), polyuréthane thermoplastique (TPU), éthylène-acétate de vinyle (EVA) ou équivalent, caractérisé en ce qu’il comprend le feuilletage du vitrage préalablement à son laquage.The inventors sought to resolve these problems by means of the invention which, consequently, relates to a process for manufacturing a lacquered laminated glazing comprising at least two sheets of mineral glass such as soda-lime, aluminosilicate, borosilicate, two such consecutive sheets. being bonded to each other via an interlayer adhesive layer such as polyvinyl butyral (PVB), thermoplastic polyurethane (TPU), ethylene vinyl acetate (EVA) or the like, characterized in that it includes the laminating of the glazing prior to its lacquering.
Le vitrage feuilleté est ainsi lavé, la laque est ensuite déposée.The laminated glazing is thus washed, the lacquer is then deposited.
Les températures de préchauffe éventuelle du verre (préalable à l’application de la laque) et de cuisson et séchage de la laque seront décrites plus en détails ci-dessous; elles ne sont pas de nature à altérer la couche adhésive intercalaire, quelle qu’en soit la nature.The temperatures of possible preheating of the glass (prior to applying the lacquer) and of cooking and drying of the lacquer will be described in more detail below; they are not likely to alter the interlayer adhesive layer, whatever the nature.
De préférence, la laque est aqueuse. Elle peut contenir des particules métalliques.Preferably, the lacquer is aqueous. It may contain metallic particles.
Le vitrage peut être découpé après son laquage. Cependant, avantageusement, le procédé de l’invention comprend la découpe du vitrage après le feuilletage et avant le laquage. De telles découpes après le feuilletage sont réservées aux cas où le vitrage feuilleté comprend deux feuilles de verre, car la découpe industrielle du verre feuilleté à trois feuilles de verre et plus est impossible. Le laquage de vitrages feuilletés découpés permet d’élargir considérablement la gamme de couleurs (presque à l’infini car directement produit à la demande du client).The glazing can be cut after its lacquering. However, advantageously, the method of the invention comprises cutting the glazing after lamination and before lacquering. Such cuts after lamination are reserved for cases where the laminated glazing comprises two glass sheets, since industrial cutting of laminated glass with three glass sheets and more is impossible. The lacquering of cut laminated glazing makes it possible to considerably widen the range of colors (almost to infinity because directly produced at the request of the customer).
Ainsi l’invention permet-elle de proposer un verre à l’unité ou faire des séries sans contrainte d’épaisseur.Thus, the invention makes it possible to offer a single lens or to make series without thickness constraints.
De préférence, l’une au moins des feuilles de verre du vitrage feuilleté laqué est recuite, trempée thermiquement ou renforcée chimiquement. Les températures de cuisson et séchage de la laque sont relativement faibles, et les températures de préchauffe du verre (préalable à l’application de la laque) plus faibles encore, et dans les deux cas trop faibles pour affecter le traitement de recuisson, la trempe thermique ou le renforcement chimique auquel ou à laquelle aurait été soumise au moins une feuille de verre constitutive du vitrage feuilleté.Preferably, at least one of the glass sheets of the lacquered laminated glazing is annealed, thermally toughened or chemically reinforced. The baking and drying temperatures of the lacquer are relatively low, and the preheating temperatures of the glass (prior to the application of the lacquer) still lower, and in both cases too low to affect the annealing treatment, the tempering thermal or chemical reinforcement to which or to which at least one constituent glass sheet of the laminated glazing has been subjected.
De préférence, le laquage est effectué par pulvérisation (spray en anglais) ou par rouleau.Preferably, the lacquering is carried out by spraying (spray in English) or by roller.
De préférence, le laquage est effectué sur une face principale du vitrage feuilleté, en pleine face ou partiellement notamment en marie-louise selon un cadre. Dans ce dernier cas, le laquage peut être effectué au moyen d’un rouleau différent de celui employé pour une application en pleine face.Preferably, the lacquering is carried out on a main face of the laminated glazing, in full face or partially in particular in Marie-louise according to a frame. In the latter case, the lacquering can be carried out using a different roller from the one used for full face application.
De préférence, le laquage comprend la cuisson de la laque dans un four de séchage, à une température maximale n’excédant pas 130 °C, et à une température d’au moins 70 °C pendant moins de deux minutes. L’application de la laque est effectuée à température ambiante, éventuellement après une préchauffe du verre à des températures atteignant au maximum des valeurs inférieures à 70 °C, et des valeurs au moins égales à 50 °C pendant moins de deux minutes également.Preferably, the lacquering comprises baking the lacquer in a drying oven, at a maximum temperature not exceeding 130 ° C, and at a temperature of at least 70 ° C for less than two minutes. The lacquer is applied at room temperature, possibly after preheating the glass to temperatures reaching a maximum of values below 70 ° C, and values at least equal to 50 ° C for less than two minutes as well.
Ces températures subies par le vitrage feuilleté sont très faibles comparées à ce que peut subir un vitrage feuilleté lors d’un test haute température (en anglais bake test) selon la norme EN12543.These temperatures experienced by laminated glazing are very low compared to what laminated glazing can undergo during a high temperature bake test according to standard EN12543.
Le temps d’exposition du vitrage feuilleté à ces températures est également très court.The exposure time of laminated glazing to these temperatures is also very short.
Selon une caractéristique distinctive du procédé de l’invention, le laquage produit un dépôt résiduel de laque sur le chant du vitrage feuilleté. Il s’agit selon les techniques d’application de laque, d’un dépôt plus ou moins irrégulier, en mouchetis ou traînées par exemple, constituant un marqueur du procédé.According to a distinctive feature of the process of the invention, the lacquering produces a residual lacquer deposit on the edge of the laminated glazing. Depending on the lacquer application techniques, this involves a more or less irregular deposit, in speckles or streaks for example, constituting a marker of the process.
De préférence, le procédé de l’invention comprend une dernière opération (finition) qui consiste à façonner les chants du vitrage feuilleté. La tenue de laque rend possible en effet de façonner le verre pour retrouver le côté brillant sur les chants.Preferably, the method of the invention comprises a final operation (finishing) which consists in shaping the edges of the laminated glazing. The lacquer hold makes it possible to shape the glass to find the shiny side on the edges.
Un autre objet de l’invention consiste en l’application d’un vitrage feuilleté laqué obtenu par un procédé comme décrit ci-dessus pour l’intérieur, comme cloisons intérieures pour les bureaux, ou ameublement. Le terme «intérieur» désigne ici tout espace intérieur, c’est-à-dire non exposé à l’atmosphère extérieure.Another object of the invention is the application of lacquered laminated glazing obtained by a process as described above for the interior, as interior partitions for offices, or furniture. The term "interior" refers here to any interior space, that is to say, not exposed to the external atmosphere.
L’invention est maintenant illustrée par un exemple de réalisation.The invention is now illustrated by an exemplary embodiment.
Un échantillon de 30 cm X 30 cm est découpé dans un vitrage feuilleté en pleine largeur float (PLF) (6 m X 3,21 m). Le vitrage feuilleté est constitué de deux feuilles de verre sodocalcique de 3 mm d’épaisseur collées l’une à l’autre par une couche de PVB de 0,76 mm d’épaisseur. Un second échantillon ne diffère du premier que par le fait que les deux feuilles de verre ont une épaisseur de 4 mm.A 30 cm X 30 cm sample is cut from full width float (PLF) laminated glazing (6 m X 3.21 m). Laminated glazing consists of two sheets of 3mm thick soda-lime glass glued together with a 0.76mm thick layer of PVB. A second sample differs from the first only in that the two sheets of glass have a thickness of 4 mm.
On applique sur l’une des deux faces principales de chaque échantillon une laque aqueuse de couleur bleu nuit, commercialisée par la Société ICA SpA (Italie) sous la dénomination Laque Hydro sur Verre (LHV) et la référence 172 LP 19. La laque est appliquée par pulvérisation, après une préchauffe du verre à une température s’élevant de la température ambiante à 63 °C en 1 min 30 s, puis redescendant à l’ambiante en passant à 40 °C en moins de 3 min. Après l’application de la laque, on cuit et sèche la laque par élévation de la température de l’ambiante à 120 °C en 6 min maximum, puis redescente à l’ambiante en moins de 2 min. La ligne de pulvérisation provient de la Société Cefla (Italie).A midnight blue aqueous lacquer, marketed by the company ICA SpA (Italy) under the name Laque Hydro sur Verre (LHV) and the reference 172 LP 19, is applied to one of the two main faces of each sample. The lacquer is applied by spraying, after preheating the glass to a temperature rising from room temperature to 63 ° C in 1 min 30 s, then dropping down to room temperature, passing to 40 ° C in less than 3 min. After applying the lacquer, the lacquer is baked and dried by raising the ambient temperature to 120 ° C in 6 min maximum, then lowering to ambient in less than 2 min. The spraying line comes from the Company Cefla (Italy).
Un test haute température (bake test en anglais) selon la norme EN12543 sur le vitrage feuilleté a été réalisé ainsi qu’une mesure d’adhésion avant et après laquage. Aucune dérive n’a été observée.A high temperature test (bake test in English) according to standard EN12543 on laminated glazing was carried out as well as an adhesion measurement before and after coating. No drift was observed.
L’intérêt est de pouvoir répondre au marché très vite avec une gamme produit considérablement élargie.The advantage is being able to respond to the market very quickly with a considerably extended product range.
On peut imaginer du feuilleté laqué trempé thermiquement ou renforcé chimiquement.One can imagine thermally toughened or chemically reinforced lacquered laminate.
La suppression du silane, primaire d’adhésion entre la laque et le PVB, utilisé actuellement, apporte aussi un avantage en termes d’environnement, hygiène et sécurité.The elimination of silane, the adhesion primer between lacquer and PVB, currently used, also provides an advantage in terms of environment, hygiene and safety.
Ce procédé a la particularité de laisser un dépôt de peinture sur le chant du verre feuilleté. Ce défaut permet de distinguer un verre laqué qui aurait été ensuite assemblé en feuilleté avec la face laquée à l’extérieur.This process has the particularity of leaving a deposit of paint on the edge of the laminated glass. This defect makes it possible to distinguish a lacquered glass which would then have been assembled in laminate with the lacquered face on the outside.
La qualité du produit est similaire à celle d’un produit laqué actuel.The quality of the product is similar to that of a current lacquer product.
