Description

L'invention est relative à un procédé de fabrication d'un panneau décoratif comprenant un support, notamment en bois, et un revêtement superficiel décoratif obtenu par un traitement de sublimation faisant usage d'une feuille d'impression à transfert thermique de la face imprimée sur le support.The invention relates to a method of manufacturing a decorative panel comprising a support, in particular made of wood, and a surface covering decorative obtained by a sublimation treatment using a sheet thermal transfer printing of the printed side on the support.

Les procédés de revêtements superficiels décoratifs imprimés par effet de sublimation sur des supports en matières textiles et sur des surfaces en matières naturelles ou synthétiques, notamment en bois, céramique, plastique ou métal, sont bien connus. La température et la pression nécessaires pour assurer le transfert thermique du décor de la feuille d'impression sur le support de base dépend de la nature du matériau du support, et du type des matières colorantes du décor. L'état de la technique en la matière peut être illustré par le document EP-A-14901. Il est ainsi possible de réaliser par impression des reproductions photographiques ou décoratives sur des objets ou supports devant résister par la suite à l'épreuve de la chaleur, notamment des articles ou objets utilisés dans la cuisine, le ménage, ou des plaques chauffantes. Les supports utilisés sont généralement des panneaux rigides, ou des bandes de métal ayant une surface parfaitement plane et continue pour recevoir le décor lors de l'opération de sublimation.The decorative surface coating processes printed by sublimation on textile supports and on surfaces natural or synthetic materials, especially wood, ceramic, plastic or metal, are well known. The temperature and pressure required to ensure thermal transfer of the decoration from the printing sheet to the basic support depends on the nature of the support material, and the type of coloring matters of the decoration. The state of the art in this area can be illustrated by document EP-A-14901. It is thus possible to achieve by printing of photographic or decorative reproductions on objects or supports which must subsequently withstand the heat test, in particular articles or objects used in cooking, cleaning, or plates heated. The supports used are generally rigid panels, or metal strips having a perfectly flat and continuous surface to receive the decoration during the sublimation operation.

Les procédés de fabrication de panneaux décoratifs connus à ce jour, et utilisant l'impression par sublimation, ne conviennent pas pour réaliser certains genres de revêtements d'imitation de carrelages, à cause du problème des interstices délimitant les différents carreaux pour constituer les joints apparents. Ces joints doivent en effet être positionnés en - dessous du plan des faces apparentes des carreaux. The methods of manufacturing decorative panels known to date, and using sublimation printing, not suitable for making certain kinds of imitation tile coverings, due to the problem of the interstices delimiting the various tiles to constitute the visible joints. These seals must indeed be positioned below the plan of the visible faces of the tiles.

Il a été proposé d'autre part de réaliser des panneaux décoratifs en collant directement des carreaux en céramique sur un panneau en bois, mais ce procédé artisanal nécessite par la suite un travail de finition pour réaliser les joints au moyen d'un liant ou ciment spécial, suivi d'un nettoyage minutieux des carreaux.It has also been proposed to produce decorative panels by sticking directly ceramic tiles on a wooden panel, but this artisanal process subsequently requires finishing work to achieve the joints with a special binder or cement, followed by thorough cleaning tiles.

Une autre solution connue consiste à réaliser un placage d'une feuille décorative d'imitation carrelages sur un support bois. Le placage s'effectue par collage au moyen d'une colle spéciale, mais sa mise en oeuvre est compliquée et onéreuse.Another known solution consists in plating a sheet decorative imitation tiles on a wooden support. Plating is done by gluing with a special glue, but its implementation is complicated and expensive.

Un premier objet de l'invention consiste à élaborer un nouveau procédé de fabrication d'un panneau décoratif d'imitation de carrelages, facile à mettre en oeuvre.A first object of the invention consists in developing a new method of manufacture of a decorative panel imitating tiles, easy to install artwork.

Un deuxième objet de l'invention consiste à réaliser un panneau décoratif d'imitation de carrelages résistant à des chocs thermiques et mécaniques, et bénéficiant d'un coût de fabrication réduit.A second object of the invention consists in making a decorative panel imitation of tiles resistant to thermal and mechanical shocks, and benefiting from a reduced manufacturing cost.

Le procédé selon l'invention est caractérisé par les étapes successives suivantes :

  • rainurer préalablement la surface du support pour obtenir un ensemble de carreaux élémentaires séparés les uns des autres par des rainures ayant une profondeur pouvant être comprise entre 0,1 mm et 5 mm,
  • appliquer par projection une couche primaire de peinture d'épaisseur homogène sur la face rainurée du support pour recouvrir les carreaux et les rainures de séparation, ladite peinture ayant des constituants chimiques de même nature que les colorants sublimables de la face imprimée de la feuille d'impression, laquelle présente une structure souple,
  • poser la face imprimée de ladite feuille sur la couche primaire de peinture après séchage de cette dernière,
  • effectuer l'opération de sublimation au moyen d'une presse fonctionnant sous une pression supérieure à 3 bars, et à une température située entre 170°C et 250°C, et prenant appui sur la face non imprimée de la feuille d'impression,
  • enlever la feuille d'impression en fin d'opération de transfert thermique du décors sur la couche primaire de peinture,
  • et enduire finalement la surface imprimée du support au moyen d'une couche de vernis de protection à base d'une résine thermodurcissable résistant à la chaleur et ayant une viscosité adaptée à la pénétration dans les rainures de manière à constituer après séchage du vernis, un panneau d'imitation carrelages avec des joints apparents et un décor spécifique parfaitement protégé contre les chocs mécaniques et thermiques.
The method according to the invention is characterized by the following successive steps:
  • grooving the surface of the support beforehand to obtain a set of elementary tiles separated from each other by grooves having a depth which may be between 0.1 mm and 5 mm,
  • applying by spraying a primary layer of paint of uniform thickness on the grooved face of the support to cover the tiles and the separation grooves, said paint having chemical constituents of the same nature as the sublimable dyes of the printed face of the sheet of impression, which has a flexible structure,
  • place the printed side of said sheet on the primary layer of paint after the latter has dried,
  • perform the sublimation operation by means of a press operating at a pressure greater than 3 bars, and at a temperature between 170 ° C and 250 ° C, and bearing on the unprinted side of the printing sheet,
  • remove the printing sheet at the end of the heat transfer operation from the decorations to the primary layer of paint,
  • and finally coating the printed surface of the support by means of a layer of protective varnish based on a thermosetting resin resistant to heat and having a viscosity suitable for penetration into the grooves so as to constitute, after drying of the varnish, a imitation tile panel with visible joints and a specific decoration perfectly protected against mechanical and thermal shocks.

De préférence, on utilise une défonceuse pour réaliser les rainures, l'outil de la défonceuse étant choisi et réglé pour réaliser des rainures de profilés prédéterminés. Les rainures présentent un profil en U à fond droit ou incurvé.Preferably, a router is used to make the grooves, the the router being chosen and adjusted to make profile grooves predetermined. The grooves have a U-shaped profile with a straight or curved bottom.

Pour obtenir un effet optimum de l'impression lors du traitement de sublimation, la largeur des rainures (14) est avantageusement comprise entre 1 mm et 10 mm. La finition des joints est ensuite obtenue automatiquement lors de l'enduction complète de la face imprimée du support par la couche de vernis de protection superficielle.To get the best effect from printing when processing sublimation, the width of the grooves (14) is advantageously between 1 mm and 10 mm. The joint finish is then obtained automatically during the complete coating of the printed face of the support by the layer of surface protection varnish.

Le support peut être formée par un panneau en bois, particules de bois agglomérées, ou en matière plastique.The support can be formed by a wooden panel, wood particles agglomerated, or plastic.

Selon un mode de réalisation préférentiel du panneau décoratif selon l'invention, on utilise :

  • un support notamment en bois, ayant une surface plane équipée d'une série de rainures présentant un profil en U à fond droit ou incurvé, pour délimiter un ensemble de carreaux élémentaires, chaque rainure ayant une profondeur comprise entre 0,1 mm et 5 mm, et une largeur comprise entre 1 mm et 10 mm,
  • une couche primaire de peinture enduite de manière homogène sur la surface rainurée du support, et destinée à recevoir par transfert thermique une impression de colorants sublimables ayant des constituants chimiques de même nature que ceux utilisés dans ladite peinture de la couche primaire,
  • une couche de vernis de protection à base de résine thermodurcissable appliquée sur la totalité de la face imprimée du support pour former un revêtement de protection à haute tenue mécanique et thermique.
According to a preferred embodiment of the decorative panel according to the invention, use is made of:
  • a support in particular made of wood, having a flat surface equipped with a series of grooves having a U-profile with a straight or curved bottom, to delimit a set of elementary tiles, each groove having a depth of between 0.1 mm and 5 mm , and a width between 1 mm and 10 mm,
  • a primary layer of paint homogeneously coated on the grooved surface of the support, and intended to receive by thermal transfer an impression of sublimable dyes having chemical constituents of the same nature as those used in said painting of the primary layer,
  • a layer of protective varnish based on thermosetting resin applied to the entire printed face of the support to form a protective coating with high mechanical and thermal resistance.

D'autres avantages et caractéristiques ressortiront plus clairement de la description qui va suivre d'un mode de mise en oeuvre du procédé selon l'invention, donné à titre d'exemple non limitatif et dont les étapes sont illustrées sur les figures suivantes dans lesquelles :

  • la figure 1 montre le support après l'opération de défonçage ;
  • la figure 2 est une vue en plan de la figure 1 ;

  • la figure 5 montre la phase de transfert thermique par effet de sublimation ;
  • la figure 6 illustre le panneau après enduction de la couche de vernis de protection ;
  • la figure 7 est une vue en plan de la figure 6.
Other advantages and characteristics will emerge more clearly from the description which follows of an embodiment of the method according to the invention, given by way of nonlimiting example and the steps of which are illustrated in the following figures in which :
  • Figure 1 shows the support after the routing operation;
  • Figure 2 is a plan view of Figure 1;
  • Figure 3 shows the support of Figure 1 after coating a primary layer of paint;
  • Figure 4 is an identical view to Figure 2 after installation of the printing sheet;
  • Figure 5 shows the heat transfer phase by sublimation effect;
  • FIG. 6 illustrates the panel after coating with the layer of protective varnish;
  • FIG. 7 is a plan view of FIG. 6.

En référence aux figures 1 et 2, un support 10 constitué par un panneau de bois, notamment à particules agglomérées, est rainuré sur sa face superficielle 12 plane pour réaliser un réseau de rainures 14 horizontales et verticales. Cette opération préalable de rainurage est réalisée au moyen d'une défonceuse, notamment à commande manuelle ou numérique, de manière à obtenir un quadrillage de carreaux 16 élémentaires séparés les uns des autres par les rainures 14. With reference to FIGS. 1 and 2, a support 10 constituted by a panel of wood, in particular with agglomerated particles, is grooved on its face superficial 12 flat to produce a network of horizontal grooves 14 and vertical. This preliminary grooving operation is carried out using a router, especially with manual or digital control, so as to obtain a grid of 16 elementary tiles separated the from each other by the grooves 14.

Les rainures 14 peuvent avoir des sections à fonds rectilignes ou incurvés, dont les dimensions sont adaptées à la mise en oeuvre d'un procédé d'impression par sublimation de la face superficielle 12. La profondeur de la totalité des rainures 14 est identique, et peut être comprise entre 0,1 mm et 5 mm. La largeur est de préférence choisie dans une fourchette comprise entre 1 mm et 10 mm.The grooves 14 may have sections with straight or curved bottoms, whose dimensions are adapted to the implementation of a process sublimation printing of the surface 12. The depth of the all of the grooves 14 are identical, and can be between 0.1 mm and 5 mm. The width is preferably chosen within a range between 1 mm and 10 mm.

Sur la figure 3, on applique par pulvérisation une couche primaire de peinture 18 sur la face superficielle 12 de support 10, de manière à recouvrir l'ensemble des carreaux 16, ainsi que les faces des rainures 14. La peinture utilisée peut être une laque blanche, notamment une résine à base de silicone, de polyester ou de polyuréthanne. Un vernis peut également être utilisé pour un panneau en mélaminé blanc. La pulvérisation de la peinture s'effectue au pistolet de manière à obtenir une couche d'épaisseur homogène.In FIG. 3, a primary layer of paint is applied by spraying. 18 on the surface 12 of support 10, so as to cover all of the tiles 16, as well as the faces of the grooves 14. The paint used can be a white lacquer, in particular a resin based on silicone, polyester or polyurethane. A varnish can also be used for a white melamine panel. Spraying paint sprayed in such a way as to obtain a thick layer homogeneous.

Après séchage de la couche primaire de peinture 18, on y applique la face imprimée d'une feuille d'impression 20 souple (figure 4) ayant des pigments colorants sublimables réalisant un décor spécifique. La peinture 18 a de préférence des constituants chimiques de même nature que les colorants sublimables. La feuille d'impression 20 est constituée par un papier à transfert thermique, dont la face externe non imprimée est soumise à un pressage à chaud pour assurer le transfert des pigments colorants par effet de sublimation.After drying of the primary paint layer 18, the face is applied to it printed with a flexible printing sheet (Figure 4) having pigments sublimable dyes achieving a specific decoration. Painting 18 has preferably chemical constituents of the same nature as the dyes sublimable. The printing sheet 20 is constituted by a transfer paper thermal, the external unprinted side of which is subjected to a pressing hot to ensure the transfer of coloring pigments by sublimation.

L'opération de sublimation illustrée sur la figure 5, s'effectue au moyen d'une presse 22 fonctionnant sous une pression de contact supérieure à 3 bars, et à une température située entre 170°C et 250°C selon le type de pigments présents sur la feuille d'impression 20. Le chauffage et la pression sur la face non imprimée provoquent le transfert du décor de la feuille d'impression 20 vers la couche primaire de peinture 18, de manière à recouvrir à la fois les carreaux 16 et les faces des rainures 14. Après cette opération de transfert thermique, la feuille 20 est enlevée définitivement, laissant apparaítre la couche d'enduction imprimée du support 10.The sublimation operation illustrated in FIG. 5 is carried out by means of a press 22 operating under a contact pressure greater than 3 bars, and at a temperature between 170 ° C and 250 ° C depending on the type of pigments present on the printing sheet 20. Heating and pressure on the face not printed cause the transfer of the decoration of the printing sheet 20 towards the primary layer of paint 18, so as to cover both the tiles 16 and the faces of the grooves 14. After this transfer operation thermal, the sheet 20 is removed permanently, revealing the printed coating layer of the support 10.

A la figure 6, une couche de vernis 24 est appliquée finalement sur toute la surface imprimée du support 10 pour former le revêtement de finition du panneau décoré. Le vernis peut être à la base d'une résine thermodurcissable additionnée d'un agent durcisseur pour réaliser une couche superficielle de protection du décor. Le vernis est de préférence choisi pour résister à des chocs thermiques de l'ordre de 200°C à 250°C, tout en conservant une bonne tenue mécanique. Le dosage approprié du vernis 24 lui confère une viscosité adaptée à sa pénétration dans les rainures 14 lors de la phase d'enduction.In FIG. 6, a layer of varnish 24 is finally applied over the entire printed surface of the support 10 to form the finishing coating of the decorated panel. The varnish can be based on a thermosetting resin added with a hardening agent to produce a surface layer of decoration protection. The varnish is preferably chosen to resist thermal shock of the order of 200 ° C to 250 ° C, while retaining good mechanical strength. The appropriate dosage of varnish 24 gives it a viscosity adapted to its penetration in the grooves 14 during the coating phase.

Après durcissement de la couche de vernis 24 (figure 7), le support 10 constitue un panneau d'imitation carrelage avec des joints apparents, et un décor spécifique, bénéficiant d'une dureté de surface correcte, et une résistance élevée à la déformation en présence de températures élevées.After the varnish layer 24 has hardened (FIG. 7), the support 10 constitutes an imitation tile panel with visible joints, and a specific decoration, benefiting from a correct surface hardness, and a high resistance to deformation in the presence of high temperatures.

Il est clair que la forme et la dimension des carreaux 16 peuvent être modifiées facilement. Il suffit d'ajuster ou de programmer le déplacement de l'outil de défonceuse avant l'opération de sublimation pour obtenir un profil de rainures 16 désiré. La dimension des rainures reste identique à celle définie précédemment. Le support 10 en bois pourrait bien entendu être remplacé par un panneau en matière plastique.It is clear that the shape and the size of the tiles 16 can be easily changed. Just adjust or program the movement of the router tool before the sublimation operation to obtain a grooves 16 desired. The size of the grooves remains identical to that defined previously. The wooden support 10 could of course be replaced by a plastic panel.
