Description
Description Titre de l'invention : Procédé d'habillage de pièces intérieures de véhicules, pièces habillées et véhicules associés Description Title of the invention: Method for dressing interior parts of vehicles, dressed parts and associated vehicles
[0001] La présente invention s'inscrit dans le cadre des habillages de pièces intérieures de véhicules automobiles à l'aide de matériaux naturels tels que les feuilles de pierre. The present invention falls within the framework of the trimmings of interior parts of motor vehicles using natural materials such as sheets of stone.
[0002] Cette technologie apparue ces dernières années est notamment décrite dans les brevets US 2016/0107418 (complexage d'une fine couche de pierre avec une colle avec une couche de maintien en matière textile) et de la société Hyundaï Motor Company, US 6547910 de Daimler Chrysler AG et US 2004/0121089 de Hanton & Williams LLP qui décrit notamment l'habillage d'une pièce automobile avec un complexe tel que celui précité. [0002] This technology, which has appeared in recent years, is described in particular in patents US 2016/0107418 (lamination of a thin layer of stone with an adhesive with a supporting layer of textile material) and of the company Hyundaï Motor Company, US 6547910 from Daimler Chrysler AG and US 2004/0121089 from Hanton & Williams LLP which describes in particular the covering of an automobile part with a complex such as that mentioned above.
[0003] Elle passe par la réalisation d'une fine couche minérale, extraite d'un bloc de pierre à l'aide d'un polymère adhésif déposé sur ce bloc de pierre ; on extrait la fine couche en question par arrachement/pelage, et laminage de cette fine couche de pierre sur une couche de maintien souple (en textile par exemple). It involves the production of a thin mineral layer, extracted from a block of stone using an adhesive polymer deposited on this block of stone; the thin layer in question is extracted by tearing / peeling, and rolling of this thin layer of stone on a flexible support layer (textile for example).
[0004] Afin de garantir la tenue au cahier des charges de la pièce ainsi revêtue (abrasion, tenue à la chaleur, résistance aux (iV, etc.), il est nécessaire de déposer une couche de vernis sur la surface de la couche. In order to guarantee the performance of the part thus coated (abrasion, heat resistance, resistance to (IV, etc.), it is necessary to deposit a layer of varnish on the surface of the layer.
[0005] La « mouillabilité » de beaucoup de matières naturelles, ainsi que celle de la feuille de pierre (comme la pierre naturelle) fait qu'elle change d'aspect en devenant plus foncée lorsqu'elle est vernie.The "wettability" of many natural materials, as well as that of the stone sheet (such as natural stone) causes it to change its appearance by becoming darker when it is varnished.
Or, cela nuit à la perception qualitative de l'aspect de la pièce, car en devenant plus foncée, on s'éloigne de l'aspect recherché, à savoir l'aspect originel de la pierre brute. However, this harms the qualitative perception of the aspect of the part, because by becoming darker, one moves away from the desired aspect, namely the original aspect of the rough stone.
[0006] Les dépôts précités divulguent une couche de surface de type « coating layer » : - US 2016/010741: « coating layer » (5): un film mince de peinture (paragraphes The aforementioned deposits disclose a surface layer of the "coating layer" type: - US 2016/010741: "coating layer" (5): a thin film of paint (paragraphs
[0042] et [0043[), - US 6547910: « transparent coating » aux paragraphes [0042] and [0043 [), - US 6547910: "transparent coating" in paragraphs
[6] ligne 25, [6] line 25,
[9] et à la revendication 10 de ce document. [9] and claim 10 of this document.
[0007] La définition et la nature des couches ne sont toutefois pas précisées. [0007] The definition and the nature of the layers are however not specified.
[0008] Le but de la présente invention est donc de proposer une solution, au moins partielle, à ce problème c'est-à-dire de conserver, après l'opération de vernissage, l'aspect le plus proche possible de la feuille de pierre naturelle brute. The aim of the present invention is therefore to provide an at least partial solution to this problem, that is to say to keep, after the varnishing operation, the appearance as close as possible to the sheet. of raw natural stone.
[0009] A cette fin, la présente invention utilise un primaire d'adhésion de base aqueuse du type vernis PU car il s'est avéré, de façon inattendue et surprenante, que c'est la nature de la 1'1 couche (primaire) qui est déterminante pour conserver au maximum l'aspect initial de la pierre. 2 To this end, the present invention uses an aqueous-based adhesion primer of the PU varnish type because it has turned out, unexpectedly and surprisingly, that this is the nature of the 1'1 layer (primer ) which is decisive to keep the initial appearance of the stone as much as possible. 2
[0010] De façon avantageuse, des additifs tels que des pigments ou des colorants naturels ou de synthèse, des agents de texture, etc. peuvent être rajoutés pour « rattraper » ou compenser en quelque sorte certaines caractéristiques originelles de la pierre perdues ou atténuées lors de l'opération de vernissage (aspect pailleté, rugosité, etc.). [0010] Advantageously, additives such as pigments or natural or synthetic dyes, texturing agents, and the like. can be added to "catch up" or compensate in a way certain original characteristics of the stone lost or attenuated during the varnishing operation (glittery appearance, roughness, etc.).
[0011] La présente invention a pour but de pallier ces inconvénients. The object of the present invention is to overcome these drawbacks.
[0012] A cet effet, la présente invention a pour objet un procédé d'habillage de pièces in- térieures de véhicules, en particulier de véhicules automobiles par une fine couche de matériau naturel, en particulier un matériau inorganique tel que la pierre, du verre ou de la céramique ou un matériau organique comme le bois consistant à habiller la pièce intérieure de véhicule en la revêtant d'une couche optionnelle d'adhésion sur laquelle on applique une couche de support de la fine couche de matériau naturel puis ladite fine couche de matériau naturel proprement dite, caractérisé en ce qu'on applique sur ladite fine couche de matériau naturel une couche primaire d'adhésion en polyuréthane (PU) à base aqueuse transparente avant de recouvrir le tout d'au moins une couche de surface transparente de protection, en particulier d'une ou de plusieurs couches de surface transparentes en vernis. [0012] To this end, the present invention relates to a process for covering interior parts of vehicles, in particular of motor vehicles, with a thin layer of natural material, in particular an inorganic material such as stone, glass or ceramic or an organic material such as wood consisting in dressing the interior part of the vehicle by coating it with an optional adhesion layer on which a support layer of the thin layer of natural material is applied and then said thin layer of natural material proper, characterized in that a transparent water-based polyurethane (PU) primary adhesion layer is applied to said thin layer of natural material before covering the whole with at least one transparent surface layer of protection, in particular of one or more transparent varnish surface layers.
[0013] L'invention sera mieux comprise, grâce à la description ci-après, qui se rapporte à un mode de réalisation préféré, donné à titre d'exemple non limitatif, et expliqué avec référence aux dessins schématiques annexés, dans lesquels : The invention will be better understood, thanks to the description below, which relates to a preferred embodiment, given by way of non-limiting example, and explained with reference to the accompanying schematic drawings, in which:

[0016] Comme on peut le voir sur la figure 1, le produit obtenu grâce à la mise en oeuvre du procédé d'habillage de pièces intérieures 1 de véhicules selon l'invention, en particulier de véhicules automobiles peut, par exemple s'appliquer à un panneau intérieur d'une portière. As can be seen in Figure 1, the product obtained by implementing the method of dressing interior parts 1 of vehicles according to the invention, in particular of motor vehicles can, for example be applied to an interior panel of a door.
[0017] On habille ainsi par une fine couche 4 de matériau naturel, en particulier un matériau inorganique tel que la pierre, du verre ou de la céramique ou un matériau organique comme le bois, la pièce intérieure 1 de véhicule en la revêtant d'une couche optionnelle (facultative) d'adhésion 2 sur laquelle on applique une couche de support 3 de la fine couche 4 de matériau naturel puis ladite fine couche 4 de matériau naturel proprement dite.Thus dressed by a thin layer 4 of natural material, in particular an inorganic material such as stone, glass or ceramic or an organic material such as wood, the interior part 1 of the vehicle by coating it with an optional (optional) adhesion layer 2 on which is applied a support layer 3 of the thin layer 4 of natural material and then said thin layer 4 of natural material proper.
Le procédé est caractérisé en ce qu'on applique sur ladite fine couche 4 de matériau naturel une couche primaire d'adhésion 5 en polyuréthane (PU) à base aqueuse transparente avant de recouvrir le tout d'au moins une couche de surface 6, 6' transparente de protection, en particulier d'au moins une couche de vernis. The method is characterized in that one applies to said thin layer 4 of natural material a primary adhesion layer 5 of transparent water-based polyurethane (PU) before covering the whole with at least one surface layer 6, 6. transparent protective, in particular at least one layer of varnish.
[0018] Dans un mode de réalisation particulier, on procède à une étape de surmoulage direct de la couche de support 3 avec ladite fine couche 4 de matériau naturel.In a particular embodiment, one proceeds to a step of direct molding of the support layer 3 with said thin layer 4 of natural material.
Dans ce cas la couche d'adhésion 2 n'est pas nécessaire. 3 In this case, the adhesion layer 2 is not necessary. 3
[0019] A titre d'exemple non limitatif, la couche primaire d'adhésion 5 est un produit bouche-pores polyuréthane mono-composant à base aqueuse et contenant des éthers de glycol tels que le butoxyéthanol et le méthoxyéthanol.By way of nonlimiting example, the primary adhesion layer 5 is a mono-component polyurethane pore filler product based on water and containing glycol ethers such as butoxyethanol and methoxyethanol.
Il est pulvérisé manuellement ou automatiquement selon une épaisseur de 10 microns minimum, subissant ensuite un séchage ou une cuisson avec une température minimum de 45 'C. It is sprayed manually or automatically to a minimum thickness of 10 microns, then undergoing drying or baking with a minimum temperature of 45 ° C.
[0020] Toujours, à titre d'exemple non limitatif, la couche de surface 6, 6' transparente peut être réalisée avec un vernis transparent polyuréthane hi-composants, contenant des solvants tel que l'acétate de butyle, d'une épaisseur de 20 microns minimum avec un séchage à l'air ambiant. Still, by way of non-limiting example, the transparent surface layer 6, 6 'can be produced with a transparent hi-component polyurethane varnish, containing solvents such as butyl acetate, with a thickness of 20 microns minimum with ambient air drying.
[0021] Pour un vernis de décor, on pourra prendre, à titre d'exemple non limitatif, cc même vernis transparent polyuréthane hi-composants d'une épaisseur au moins équivalente, appliqué et séché de manière identique.For a decorative varnish, we can take, by way of non-limiting example, cc same transparent polyurethane hi-component varnish of at least equivalent thickness, applied and dried in an identical manner.
Un autre exemple non limitatif est un vernis transparent polyuréthane hi-composants auquel des éléments texturants ont été rajoutés.Another non-limiting example is a transparent hi-component polyurethane varnish to which texturizing elements have been added.
Un autre exemple est un vernis transparent polyuréthane hi-composants auquel des pigments non organiques ont été rajoutés. Another example is a transparent hi-component polyurethane varnish to which inorganic pigments have been added.
[0022] Conformément à la présente invention, le procédé est encore caractérisé en ce que la pièce intérieure 1 de véhicule est réalisée en une matière synthétique, telle qu'une matière plastique de type polycarbonate (PC), en PC-ABS, en polypropylène (PP) ou en polyuréthane et polypropylène (PU+PP), notamment en PU+PP chargé de fibres de verre et/ou de fibres naturelles. According to the present invention, the method is further characterized in that the interior part 1 of the vehicle is made of a synthetic material, such as a plastic material of the polycarbonate (PC) type, of PC-ABS, of polypropylene. (PP) or in polyurethane and polypropylene (PU + PP), in particular in PU + PP filled with glass fibers and / or natural fibers.
[0023] Avantageusement, et selon un mode de réalisation préféré, le procédé selon l'invention est caractérisé en ce que la couche d'adhésion 2 est réalisée en colle PUR (polyuréthane) en base aqueuse. Advantageously, and according to a preferred embodiment, the method according to the invention is characterized in that the adhesion layer 2 is made of PUR (polyurethane) adhesive in aqueous base.
[0024] Avantageusement, selon un autre mode de réalisation, le procédé selon l'invention est caractérisé en ce que la couche d'adhésion 2 est réalisée en une colle ne contenant pas de PUR (polyuréthane) et en une base solvantée non-aqueuse. Advantageously, according to another embodiment, the method according to the invention is characterized in that the adhesion layer 2 is made of an adhesive not containing PUR (polyurethane) and of a non-aqueous solvent base .
[0025] Selon une autre caractéristique avantageuse, la couche de support 3 de la fine couche 4 de matériau naturel est réalisée dans une matière textile tissée ou non-tissée et présente une épaisseur allant de 100 pm à 5 mm.According to another advantageous characteristic, the support layer 3 of the thin layer 4 of natural material is made of a woven or non-woven textile material and has a thickness ranging from 100 μm to 5 mm.
Cette matière textile peut être recouverte optionnellement avec une résine classique adaptée, bien connue de l'homme du métier, ou non. This textile material can optionally be covered with a suitable conventional resin, well known to those skilled in the art, or not.
[0026] Avantageusement, le procédé selon l'invention est caractérisé en ce que la fine couche 4 de matériau naturel est réalisée en pierre, verre, céramique ou bois et présente une épaisseur allant de 50 pm à 2 mm. Advantageously, the method according to the invention is characterized in that the thin layer 4 of natural material is made of stone, glass, ceramic or wood and has a thickness ranging from 50 μm to 2 mm.
[0027] Conformément à la présente invention, la couche primaire 5 d'adhésion transparente, par exemple en PU, présente une épaisseur de 10 'lm au minimum de préférence allant de 10 pm à 40 pm, et plus préférentiellement une épaisseur allant de 10 pin à 15 pm. According to the present invention, the primary transparent adhesion layer 5, for example made of PU, has a thickness of at least 10 ′ lm, preferably ranging from 10 μm to 40 μm, and more preferably a thickness ranging from 10 μm to 40 μm. pine at 15 pm.
[0028] Avantageusement ladite couche primaire 5 présente au moins un additif qui compense une perte d'une caractéristique visuelle ou tactile originelle ou ajoute une caractéristique visuelle ou tactile supplémentaire au matériau naturel, notamment une caractéristique perdue suite à l'opération de dépôt de la ou des couches de surface 6, 6' de protection, par exemple en vernis.Advantageously, said primary layer 5 has at least one additive which compensates for a loss of an original visual or tactile characteristic or adds an additional visual or tactile characteristic to the natural material, in particular a characteristic lost following the operation of depositing the or protective surface layers 6, 6 ', for example of varnish.
Alternativement, l'au moins un additif précité peut être présent dans ladite ou lesdites couches de protection 6, 6' en plus ou à la place de celui ou ceux présents dans ladite couche primaire 5. Alternatively, the at least one aforementioned additive may be present in said one or more protective layers 6, 6 'in addition to or in place of that or those present in said primary layer 5.
[0029] Selon encore un autre aspect, la ou les couches de surface de protection 6, 6' ap- pliquées comprennent au moins une couche de laque PU solvant& transparente. [0029] According to yet another aspect, the applied protective surface layer or layers 6, 6 ′ comprise at least one layer of solvent & transparent PU lacquer.
[0030] Avantageusement, le procédé selon l'invention est en outre caractérisé en ce que la couche ou l'ensemble des couches de surface 6, 6' de protection, par exemple de vernis, présente une épaisseur allant de 15 prn à 300 pm, en particulier de 40 pm à 60 Advantageously, the method according to the invention is further characterized in that the layer or all of the surface layers 6, 6 'of protection, for example of varnish, has a thickness ranging from 15 μm to 300 μm , especially from 40 pm to 60
[0031] La présente invention a également pour objet une pièce intérieure 1 de véhicule habillée grâce à la mise en oeuvre du procédé selon l'invention et un véhicule, notamment un véhicule automobile caractérisé en ce qu'il présente au moins une pièce intérieure 1 habillée grâce à la mise en oeuvre du procédé selon l'invention. The present invention also relates to an interior part 1 of a vehicle dressed thanks to the implementation of the method according to the invention and a vehicle, in particular a motor vehicle characterized in that it has at least one interior part 1 dressed thanks to the implementation of the method according to the invention.
[0032] Comme évoqué plus haut, la figure 1 montre l'ensemble des couches déposées pour former l'habillage de la pièce intérieure 1, par exemple un élément de portière ou de tableau de bord d'une voiture de tourisme ou de sport. As mentioned above, Figure 1 shows all of the layers deposited to form the covering of the interior part 1, for example a door or dashboard element of a passenger or sports car.
[0033] Comme on peut le voir sur la photo de la figure 2, l'utilisation d'une sous-couche d'adhésion autre que de nature aqueuse ne donne pas le résultat escompté.As can be seen in the photo of Figure 2, the use of an adhesion sub-layer other than aqueous nature does not give the expected result.
On voit sur cet exemple la différence d'aspect sur une feuille où le matériau naturel est de l'ardoise qui a été vernie avec le même vernis de surface.We see in this example the difference in appearance on a sheet where the natural material is slate which has been varnished with the same surface varnish.
Avec la sous-couche primaire de vernis aqueux, conformément à la présente invention, on obtient un aspect proche de celui de la pierre brute originelle alors qu'avec un vernis solvanté l'aspect est plus sombre, ce qui peut être souhaité dans certains cas ou au contraire un effet non recherché. With the primer undercoat of aqueous varnish, in accordance with the present invention, an appearance close to that of the original rough stone is obtained, while with a solvent-based varnish the appearance is darker, which may be desired in certain cases. or on the contrary an unwanted effect.
[0034] Bien entendu, l'invention n'est pas limitée au mode de réalisation décrit et représenté aux dessins annexés.Of course, the invention is not limited to the embodiment described and shown in the accompanying drawings.
Des modifications restent possibles, notamment du point de vue de la constitution des divers éléments ou par substitution d'équivalents techniques, sans sortir pour autant du domaine de protection de l'invention. 5Modifications remain possible, in particular from the point of view of the constitution of the various elements or by substitution of technical equivalents, without thereby departing from the scope of protection of the invention. 5
