Description

PROCEDE DE REVETEMENT PAR ENROBAGE ET PANNEAU DECORATIF RESULTANT DE CE PROCEDE.COATING COATING PROCESS AND DECORATIVE PANEL RESULTING THEREFROM.
L'invention concerne un procédé de revêtement par enrobage par une feuille décor d' au moins une face supérieure et au moins un bord profilé d'un panneau décoratif à base de bois, synthétique ou en matière composite.The invention relates to a process for coating by a decorative sheet of at least one upper face and at least one profiled edge of a decorative panel based on wood, synthetic or composite material.
L'invention concerne encore les panneaux issus d'un tel procédé.The invention also relates to panels derived from such a method.
La présente invention concerne le domaine de la fabrication de panneaux décors pour revêtement de sols, de mur ou plafond.The present invention relates to the field of manufacturing decorative panels for flooring, wall or ceiling.
Tout particulièrement, en tant que panneau décor l'on connaît les revêtements de sol dits stratifiés sous forme de lames dont les bords sont équipés de moyens d' emboîtement de type rainure et languette et qui ont été débités à partir de panneaux de grande surface mélaminés . Sur ces derniers ont été appliqués , par pressage à chaud, en face supérieure, une feuille décor imprégnée de mélamine et un overlay et, en face inférieure, une balance, très souvent sous forme d'une feuille cellulosique, type papier kraft.In particular, as a decorative panel, it is known so-called laminated floor coverings in the form of blades whose edges are equipped with tongue and groove type interlocking means and which have been cut from panels of large melamine surface. . On the latter were applied, by hot pressing, on the upper side, a melamine-impregnated decorative sheet and an overlay and, on the underside, a scale, very often in the form of a cellulosic sheet, such as kraft paper.
De tels revêtements de sols stratifiés sont particulièrement adaptés pour une pose de lames bord à bord, c'est-à-dire avec interstices se faisant le plus discret possible, mais qui, pour autant, définissent des point de faiblesse en terme de résistance à l'abrasion, aux poinçonnement et à l'humidité.Such laminate floor coverings are particularly suitable for laying boards edge to edge, that is to say with interstices making the most discrete possible, but which, for all that, define weak points in terms of resistance to abrasion, punching and moisture.
Aussi, à l'heure actuelle, un nouveau style de parquet stratifié s'est imposé sur le marché, parquet composé de lames qui, après assemblage et pose, laissent apparaître des jointures. Dans ce but, les bords de ces lames sont profilés, autrement dit usinés, selon le cas sous forme d' un chanfreinage ou autre . Ainsi , une fois le revêtement de sol posé, un espace sous forme d'une rainure est clairement apparent entre les lames . Evidemment, l'opération de profilage ou chanfreinage sur des lames stratifiées donne lieu à des bords visibles dépourvus de revêtement laissant apparaître le matériau composant l'âme de chacune de ces lames.Also, at present, a new style of laminate flooring has emerged on the market, flooring composed of blades that, after assembly and installation, reveal joints. For this purpose, the edges of these blades are profiled, in other words machined, depending on the case in the form of a chamfering or other. Thus, once the flooring is laid, a space in the form of a groove is clearly visible between the blades. Obviously, the operation of profiling or chamfering on laminated strips gives rise to visible edges devoid of coating revealing the material component of the core of each of these blades.
Par conséquent, une phase additionnelle de fabrication s'impose au cours de laquelle chaque chanfrein reçoit un habillage, par exemple sous la forme d'une résine d'imprégnation, tel qu'un vernis , lui conférant un aspect final , selon le cas identique ou proche, en terme de coloris, de celui de la face supérieure de la lame considérée ou, au contraire, parfaitement distinctif, de manière à mettre encore davantage en évidence la rainure entre les lames assemblées .Therefore, an additional phase of manufacture is required during which each chamfer receives a covering, for example in the form of an impregnating resin, such as a varnish, giving it a final appearance, as the case identical or close, in terms of color, that of the upper face of the blade considered or, conversely, perfectly distinctive, so as to further highlight the groove between the assembled blades.
II est encore connu de revêtir les chanfreins de ces lames d'un film décoratif déposé à partir d'un papier transfert.It is still known to coat the chamfers of these blades with a decorative film deposited from a transfer paper.
Il est encore connu la technique d'enrobage consistant à appliquer, par collage, une couche de papier enrobant sur un panneau ou une lame préalablement profilé.It is still known the coating technique of applying, by gluing, a layer of paper coating on a panel or a previously profiled blade.
Le procédé de fabrication mis en œuvre consiste à débiter, depuis des panneaux de grande dimension non décorés, des lames dont on profile les bords pour, après assemblage, former un revêtement de sol ou mural.The manufacturing method used consists of cutting, from undecorated large panels, blades whose edges are profiled for, after assembly, forming a floor or wall covering.
En particulier, de telles lames peuvent être équipées, en bordure longitudinale et/ou transversale, de moyens d'emboîtement de type rainure et languette, tout comme ils sont susceptibles d'adopter, par usinage, un profil spécifique, de forme arrondie, chanfreinée ou autre.In particular, such blades can be equipped, in longitudinal and / or transverse edge, tongue and groove type interlocking means, just as they are likely to adopt, by machining, a specific profile, of rounded, chamfered shape. Or other.
Par cette technique d'enrobage, ces lames profilées sont revêtues, tant sur leur face supérieure apparente qu'au niveau de leurs bords profilés, d'un papier décor leur conférant l'aspect décoratif souhaité. Pour l' enduction, donc le collage de la couche de papier décor, il est généralement utilisé une colle de type polyuréthane ou acétate de polyvinyle d'une très grande facilité de mise en œuvre et permettant, précisément, l'enrobage sur toute la surface de la lame, y compris au niveau de son ou ses bords profilés .By this coating technique, these profiled blades are coated, both on their visible upper face and at their profiled edges, with a decorative paper giving them the desired decorative appearance. For the coating, and therefore the bonding of the layer of decorative paper, it is generally used a polyurethane or polyvinyl acetate glue very easy to implement and allowing, precisely, the coating on the entire surface of the blade, including at its level or its profiled edges.
Pour autant de telles colles ne permettent pas d'obtenir au niveau de ces lames une surface décorative de dureté, de résistance à l'abrasion et de tenue aux chocs et à la chaleur optimale .For such glues do not obtain at these blades a decorative surface of hardness, abrasion resistance and resistance to shock and optimal heat.
On a d'ores et déjà pensé utiliser des couches de papier décor comportant une imprégnation d'un vernis améliorant sensiblement cette usure à l'abrasion. D'ailleurs, il est même connu d'augmenter cette qualité en soumettant la couche de vernis à un bombardement d'électrons qui en favorise la dureté.It has already been thought to use layers of decor paper having an impregnation of a varnish substantially improving this wear abrasion. Moreover, it is even known to increase this quality by subjecting the layer of varnish to an electron bombardment which promotes the hardness.
L'utilisation de colle plus technique, donc plus onéreuse, conduit à des revêtements de sol d'un coût de revient qui n'est pas compétitif en comparaison, par exemple, à des parquets stratifiés .The use of more technical glue, and therefore more expensive, leads to flooring costs at a cost that is not competitive in comparison, for example, with laminate flooring.
C'est dans le cadre d'une première démarche inventive que l'on a pensé faire appel à une colle de moindre coût de revient, mais qui, pour autant, répond parfaitement au cahier des charges auquel doit satisfaire un panneau décoratif pour revêtement de sol ou mural .It is in the context of a first inventive step that we thought to use a glue of lower cost, but which, for all that, perfectly meets the specifications to be met by a decorative panel for cladding. floor or wall.
En fait, il est connu de longue date d'utiliser dans le domaine du placage : la colle urée-formaldéhyde ou urée-formol, colle de la famille des thermodurcissables , réagissant sous l'effet d'un durcisseur. Tout comme pour les panneaux mélaminés, l'enrobage par enduction d'urée-formol n'est mis en œuvre que sur des panneaux de grande dimension. La conception de lames profilées partant de tels panneaux pose les mêmes problèmes que dans le cadre de lames stratifiées, à savoir l'habillage des bords profilés des lames débitées à partir de ces panneaux.In fact, it has long been known to use in the field of plating: urea-formaldehyde or urea-formaldehyde glue, glue of the thermosetting family, reacting under the effect of a hardener. As with melamine panels, the coating with urea-formaldehyde coating is only used on large panels. The design of profiled blades from such panels poses the same problems as in the case of laminated strips, namely the dressing of the profiled edges of the blades cut from these panels.
Finalement, la présente invention se veut à même de répondre à l'ensemble des problèmes évoqués ci-dessus en mettant en application cette solution d'enrobage à partir de colle urée- formol sur la face supérieure décorative des panneaux ceci en combinaison d'un enrobage par enduction d'une colle différente au niveau du ou des bords profilés d'un tel panneau, en particulier de type polyuréthane , acétate de polyvinyle, etc..Finally, the present invention is able to respond to all the problems mentioned above by applying this coating solution from urea-formaldehyde glue on the decorative upper side of the panels this in combination with a coated by coating with a different adhesive at the level or the profiled edges of such a panel, in particular of the polyurethane type, polyvinyl acetate, etc.
En fin de compte, c'est en allant à l' encontre d'un préjugé de l'homme du métier consistant en ce que la technique de l'enrobage au moyen d'une colle urée-formol ne peut s'appliquer à des panneaux profilés que la présente invention a pu se réaliser.In the end, it is counter to a prejudice of the person skilled in the art that the technique of coating with a urea-formaldehyde glue can not be applied to profiled panels that the present invention could be realized.
Il convient de remarquer que, de manière particulière, grâce à la présente invention l'on peut obtenir un panneau profilé dont la face supérieure décorative présente une parfaite tenue à l'abrasion en comparaison à des panneaux profilés revêtus par enrobage selon les techniques connues .It should be noted that, in particular, thanks to the present invention can be obtained a profiled panel whose decorative upper face has a perfect abrasion resistance in comparison to profiled panels coated by coating according to known techniques.
De manière toute aussi particulière encore, cet avantage résulte de l'emploi d'une colle d'un coût de revient permettant d'obtenir des panneaux de revêtement de sol, muraux ou autres d'un coût de fabrication très réduit.Even more particularly, this advantage results from the use of a cost of cost glue for obtaining flooring panels, walls or other very low manufacturing cost.
L'invention sera mieux comprise à la lecture de la description qui va suivre et au vu du dessin joint en annexe illustrant, de manière schématisée sur une figure unique, un panneau décoratif de type lame de revêtement de sol ou de mur, sur lequel est appliquée une feuille décor au travers du procédé selon 1' invention .The invention will be better understood on reading the description which follows and in view of the attached drawing illustrating, schematically in a single figure, a decorative panel of the type of flooring or wall blade, on which is applied a decorative sheet through the process according to the invention.
Tout particulièrement, ce procédé conforme à l'invention est un procédé d'enrobage d'un panneau décoratif 1 comportant une âme 2 qui peut être à base de bois, par exemple en MDF ou HDF ou aggloméré, tout comme elle peut être en matériau composite ou exclusivement synthétique. A noter que cette âme du panneau décoratif 1 peut être réalisée à partir de matériaux recyclés .More particularly, this method according to the invention is a method of coating a decorative panel 1 comprising a core 2 which may be based on wood, for example MDF or HDF or chipboard, just as it may be of material composite or exclusively synthetic. Note that this core of the decorative panel 1 can be made from recycled materials.
Un tel panneau décoratif 1 comporte encore une face supérieure 3 revêtue par enrobage d'une feuille décor 4 venant par ailleurs habiller au moins un des bords 5, 6 profilés que comporte ce panneau 1. Un tel profilage peut se présenter sous forme d' un arrondi, d'un chanfreinage ou autre. A noter qu'au niveau de ces bords 5 , 6 du panneau 1 peuvent être aménagés des moyens d'emboîtement, de type rainure et languette en vue de l'assemblage de ces panneaux pour la conception d'un revêtement de sol, mural ou autre.Such a decorative panel 1 also comprises an upper face 3 coated by coating a decorative sheet 4 which also covers at least one of the profiled edges 5, 6 that this panel 1 comprises. Such a profiling may be in the form of a rounded, chamfering or otherwise. Note that at these edges 5, 6 of the panel 1 can be arranged interlocking means, groove and tongue type for the assembly of these panels for the design of a floor covering, wall or other.
Selon le procédé conforme à l' invention, l' enrobage , par la feuille décor 4 du panneau 1 au niveau de sa face supérieure 3 et de son ou ses bords 5, 6 profilés, consiste en une enduction sur tout ou partie de la face supérieure 3 d'une colle urée- formol, tandis que le ou les bords profilés 5, 6 sont enduits d'une colle différente, de type acétate de polyvinyle (ou PVAC) , polyuréthane ou similaire.According to the method according to the invention, the coating, by the decorative sheet 4 of the panel 1 at its upper face 3 and its profiled edge or edges 5, 6, consists of a coating on all or part of the face upper 3 a urea-formaldehyde glue, while the profiled edge or edges 5, 6 are coated with a different glue, polyvinyl acetate type (or PVAC), polyurethane or the like.
Lorsqu'il est indiqué que la face supérieure 3 est enduite, en tout ou partie, par de la colle urée-formol, il faut entendre que cette enduction de colle peut intervenir sur une partie seulement de la largeur de la face supérieure 3 du panneau 1 , à proximité des bords 5 , 6 , pouvant être préférée une application de colle différente pour faciliter leur enrobage au moyen de la feuille décor 4. Justement, dans une autre étape du procédé selon l'invention, on procède à l'application de la feuille décor 4, notamment par calandrage, sur cette face supérieure 3 du panneau 1 et sur ce ou ces bords profilés 5, 6.When it is indicated that the upper face 3 is completely or partially coated with urea-formaldehyde glue, it is to be understood that this glue coating may intervene on only part of the width of the upper face 3 of the panel 1, close to the edges 5, 6, may be preferred a different glue application to facilitate their coating by means of the decorative sheet 4. Exactly, in another step of the method according to the invention, the decor sheet 4 is applied, in particular by calendering, on this upper face 3 of the panel 1 and on this or these profiled edges 5, 6.
A noter, tout particulièrement, que l'on peut procéder en deux étapes d'enrobage distinctes pour la face supérieure 3 du panneau 1, d'une part, et son ou ses bords profilés 5, 6, d' autre part.It should be noted, in particular, that it is possible to proceed in two distinct coating steps for the upper face 3 of the panel 1, on the one hand, and its profiled edge or edges 5, 6, on the other hand.
Dans ce cas, on enduit tout d'abord de colle urée-formol Cl toute ou partie la face supérieure 3 du panneau 1 avant d'y appliquer, par calendrage, la feuille décor 4. On procède, ensuite, à l'enduction du ou des bords 5, 6 de ce dernier au moyen d'une colle différente C2, par exemple une colle polyuréthane, avant d' appliquer sur ce ou ces bords 5 , 6, la feuille décor 4.In this case, firstly all of the upper face 3 of the panel 1 is coated first with urea-formaldehyde glue Cl before the calendar sheet 4 is applied thereto by calendering. or edges 5, 6 of the latter by means of a different adhesive C2, for example a polyurethane adhesive, before applying on this or these edges 5, 6, the decorative sheet 4.
Celle-ci peut recevoir, avant ou après enrobage, une couche de vernis sur sa face apparente 8. Par ailleurs en vue d'une application en tant que revêtement de sol, un tel vernis est susceptible de subir tout type de traitement qui viendrait en améliorer la tenue à l'abrasion.It can receive, before or after coating, a layer of varnish on its apparent face 8. Furthermore, for application as a floor covering, such a varnish is likely to undergo any type of treatment that would come into improve abrasion resistance.
Au cours de l'une ou l'autre étape de ce procédé d'enrobage, le panneau 1 peut encore être revêtu, sur sa face inférieure 9, d'une couche d'un revêtement quelconque. En particulier celui-ci peut former un contre-balancement au revêtement décor en face supérieure 3 et/ou assurer une fonction d'isolation.During one or the other step of this coating process, the panel 1 can still be coated, on its underside 9, with a layer of any coating. In particular, it may counterbalance the top facing decorative coating 3 and / or provide an insulation function.
Les avantages qui découlent de la présente invention consistent en ce que, sur la surface principale porteuse du panneau décoratif 1, peut être appliquée une colle qui, bien qu'étant d'un faible coût de revient contribue à l'obtention de performances mécaniques élevées pour de tels panneaux. The advantages which flow from the present invention are that, on the main surface carrying the decorative panel 1, can be applied an adhesive which, although being of a low cost price contributes to obtaining high mechanical performance for such panels.
