Description
1 L'invention concerne un procédé de réalisation d'un panneau d'habillage de véhicule automobile et un panneau réalisé par un tel procédé. Il est connu de mettre en oeuvre un procédé de réalisation d'un panneau d'habillage de véhicule automobile - ledit panneau étant notamment sous forme d'une tablette de recouvrement d'un compartiment à bagages dudit véhicule -, ledit panneau comprenant une âme autoportante à base de mousse de polyuréthanne, ladite âme comprenant une face d'endroit et une face d'envers, ledit panneau comprenant en outre une couche de revêtement d'endroit collée sur ladite face d'endroit, ledit procédé comprenant les étapes suivantes : - prévoir un moule comprenant une matrice et un couvercle définissant après fermeture dudit moule une cavité de moulage, - injecter sur ladite matrice un mélange précurseur de mousse de polyuréthanne rigide ou semi-rigide, - fermer ledit moule de manière à permettre l'expansion dudit mélange dans ladite cavité, - après formation de ladite mousse, démouler l'élément obtenu formant ladite âme, - coller sur ladite face d'endroit ladite couche de revêtement d'endroit - ladite couche étant notamment à base de non tissé, moquette ou tissu. Cependant, on observe couramment que l'âme obtenue par un tel moulage présente des faces d'endroit et d'envers non lisses, présentant notamment des défauts sous forme de cratères, ceci du fait de la formation de certaines bulles de taille importante qui crèvent en surface. Et la présence de la couche de revêtement d'endroit, et éventuellement d'une couche de revêtement d'envers, peut ne pas suffire à masquer les défauts de la face d'endroit, et éventuellement de la face d'envers.The invention relates to a method for producing a motor vehicle trim panel and a panel made by such a method. It is known to implement a method of producing a motor vehicle trim panel - said panel being in particular in the form of a covering shelf of a luggage compartment of said vehicle - said panel comprising a self-supporting core based on polyurethane foam, said core comprising a location face and a back face, said panel further comprising a location coating layer adhered to said location face, said method comprising the following steps: providing a mold comprising a matrix and a lid defining after closing of said mold a molding cavity, - injecting on said matrix a precursor mixture of rigid or semi-rigid polyurethane foam, - closing said mold so as to allow expansion of said mixture in said cavity, - after forming said foam, demolding the element obtained forming said core, - sticking on said surface face said layer of location coating - said layer being especially based on nonwoven, carpet or fabric. However, it is commonly observed that the core obtained by such a molding has non-smooth face and back faces, in particular having defects in the form of craters, this due to the formation of certain large bubbles that burst. surface. And the presence of the location coat layer, and possibly a back coat layer, may not be sufficient to mask the defects of the place face, and possibly the back side.
L'obtention d'un panneau d'aspect satisfaisant requiert donc une opération manuelle de finition de l'âme, consistant notamment en un rebouchage des 3032375 2 cratères formés à l'issue du moulage, ce qui complexifie sa réalisation et en augmente le coût de fabrication. L'invention a pour but de pallier cet inconvénient en proposant un procédé 5 permettant de supprimer - ou du moins minimiser - les défauts de surface observés sur les faces d'endroit et d'envers de l'âme. A cet effet, et selon un premier aspect, l'invention propose un procédé de réalisation d'un panneau d'habillage de véhicule automobile - ledit panneau étant 10 notamment sous forme d'une tablette de recouvrement d'un compartiment à bagages dudit véhicule -, ledit panneau comprenant une âme autoportante à base de mousse de polyuréthanne, ladite âme comprenant une face d'endroit et une face d'envers, ledit panneau comprenant en outre une couche de revêtement d'endroit collée sur ladite face d'endroit, ledit procédé comprenant les étapes 15 suivantes : - prévoir un moule comprenant une matrice et un couvercle définissant après fermeture dudit moule une cavité de moulage, - disposer sur ladite matrice une couche de ouate, - injecter sur ladite couche de ouate un mélange précurseur de mousse de 20 polyuréthanne rigide ou semi-rigide, - fermer ledit moule de manière à permettre l'expansion dudit mélange dans ladite cavité, - après formation de ladite mousse, dans laquelle est noyée ladite couche de ouate, démouler l'élément obtenu formant ladite âme, 25 - coller sur ladite face d'endroit ladite couche de revêtement d'endroit, ladite couche étant notamment à base de non tissé, moquette ou tissu. Par une mousse rigide ou semi rigide, on entend une mousse non élastiquement compressible telle qu'une mousse utilisée pour former un coussin de siège.Obtaining a panel of satisfactory appearance therefore requires a manual finishing operation of the core, consisting in particular of a filling of the 3032375 2 craters formed after the molding, which complicates its implementation and increases the cost Manufacturing. The object of the invention is to overcome this disadvantage by proposing a method 5 for eliminating - or at least minimizing - the surface defects observed on the face and back faces of the core. For this purpose, and according to a first aspect, the invention proposes a method of producing a motor vehicle trim panel - said panel being in particular in the form of a cover of a luggage compartment of said vehicle said panel comprising a self-supporting core based on polyurethane foam, said core comprising a location face and a backside face, said panel further comprising a location coating layer adhered to said location face, said method comprising the following steps: - providing a mold comprising a matrix and a lid defining after closing of said mold a molding cavity, - arranging a layer of wadding on said matrix, - injecting on said wadding layer a precursor foam mixture of rigid or semi-rigid polyurethane, - closing said mold so as to allow expansion of said mixture in said cavity, - after formation of said foam, in which is embedded in said wadding layer, demolding the obtained element forming said core, - sticking on said surface face said location coating layer, said layer being in particular based on nonwoven, carpet or fabric. By a rigid or semi rigid foam is meant a non-elastically compressible foam such as a foam used to form a seat cushion.
30 Un tel type de mousse présente notamment une densité comprise entre 0,12 et 0,16, étant notamment de l'ordre de 0,14.Such a type of foam has in particular a density of between 0.12 and 0.16, being in particular of the order of 0.14.
3032375 3 La demanderesse a observé, de façon surprenante, que la présence de la couche de ouate permet d'homogénéiser la taille des bulles et d'éviter la formation de bulles de taille importante qui crèvent en surface.The Applicant has observed, surprisingly, that the presence of the wadding layer makes it possible to homogenize the size of the bubbles and to avoid the formation of large bubbles that burst on the surface.
5 Il en résulte l'obtention d'un panneau présentant un aspect de surface très satisfaisant, et ceci sans opération manuelle de finition de l'âme complexifiant sa réalisation et grevant son coût de fabrication.This results in obtaining a panel having a very satisfactory surface appearance, and this without manual operation of finishing the core making it more complex and costing its manufacturing cost.
10 Selon un deuxième aspect, l'invention propose un panneau réalisé par un tel procédé. D'autres particularités et avantages de l'invention apparaîtront dans la description qui suit, faite en référence à la figure jointe qui est une représentation 15 schématique partielle en coupe d'un panneau réalisé selon un mode de réalisation. En référence aux figures, on décrit un procédé de réalisation d'un panneau 1 d'habillage de véhicule automobile - ledit panneau étant notamment sous forme 20 d'une tablette de recouvrement d'un compartiment à bagages dudit véhicule -, ledit panneau comprenant une âme 2 autoportante à base de mousse de polyuréthanne, ladite âme comprenant une face d'endroit 3 et une face d'envers 4, ledit panneau comprenant en outre une couche de revêtement d'endroit 5 collée sur ladite face d'endroit, ledit procédé comprenant les étapes suivantes : 25 - prévoir un moule comprenant une matrice et un couvercle définissant après fermeture dudit moule une cavité de moulage, - disposer sur ladite matrice une couche de ouate 6, - injecter sur ladite couche de ouate un mélange précurseur de mousse de polyuréthanne rigide ou semi-rigide - ladite mousse présentant notamment 30 une densité comprise entre 0,12 et 0,16, étant notamment de l'ordre de 0,14 -, - fermer ledit moule de manière à permettre l'expansion dudit mélange dans ladite cavité, 3032375 4 - après formation de ladite mousse, dans laquelle est noyée ladite couche de ouate, démouler l'élément obtenu formant ladite âme, - coller sur ladite face d'endroit ladite couche de revêtement d'endroit, ladite couche étant notamment à base de non tissé, moquette ou tissu.According to a second aspect, the invention proposes a panel made by such a method. Other features and advantages of the invention will appear in the description which follows, made with reference to the attached figure which is a partial schematic sectional representation of a panel made according to one embodiment. Referring to the figures, there is described a method of producing a motor vehicle trim panel 1 - said panel being in particular in the form of a cover plate of a luggage compartment of said vehicle - said panel comprising a self-supporting core 2 based on polyurethane foam, said core comprising a location face 3 and a back face 4, said panel further comprising a location coating layer 5 bonded to said location face, said method comprising the steps of: providing a mold comprising a matrix and a lid defining after closing of said mold a molding cavity; arranging on said matrix a layer of wadding 6; injecting on said wadding layer a precursor mixture of foam of rigid or semi-rigid polyurethane - said foam having in particular a density of between 0.12 and 0.16, being in particular of the order of 0.14 -, - closing said mold of mani to allow expansion of said mixture in said cavity, after formation of said foam, in which said layer of wadding is embedded, demolding the element obtained forming said core, - sticking on said face of said layer of location coating, said layer being especially based on nonwoven, carpet or fabric.
5 Il peut être prévu en outre une découpe périphérique de finition permettant de détourer l'excédent de ouate et/ou de revêtement. Pour conduire au panneau 1 de la réalisation représentée, le procédé prévoit en 10 outre une étape de collage d'une couche de revêtement d'envers 7 - notamment sous forme de non-tissé - en face d'envers 4 de l'âme 2. Selon une réalisation, la couche de ouate 6 est à base de fibres synthétiques notamment de polyester - ou naturelles - notamment de coton.In addition, it is possible to provide a peripheral finishing cutout for diverting excess cotton wool and / or coating. In order to lead to the panel 1 of the embodiment shown, the method furthermore provides a step of bonding a backing layer 7 - in particular in the form of a nonwoven - opposite the back 4 of the core 2. According to one embodiment, the wadding layer 6 is based on synthetic fibers, especially of polyester - or natural fibers - in particular of cotton.
15 Dans le cas de fibres synthétiques, on peut notamment utiliser des fibres « bicomposant » présentant une gaine fusible à température modérée, les fibres étant liées entre elles par fusion de ladite gaine.In the case of synthetic fibers, it is particularly possible to use "bicomponent" fibers having a fusible sheath at moderate temperature, the fibers being bonded together by melting said sheath.
20 Selon une réalisation, la couche de ouate 6 présente une masse surfacique comprise entre 30 et 100 g/m2, et notamment entre 60 et 80 g/m2. En particulier, la couche de ouate 6 présente une masse surfacique de l'ordre de 70 g/m2.According to one embodiment, the wadding layer 6 has a basis weight of between 30 and 100 g / m 2, and in particular between 60 and 80 g / m 2. In particular, the wadding layer 6 has a weight per unit area of about 70 g / m 2.
25 Selon une réalisation la couche de ouate 6 présente avant moulage une épaisseur comprise entre 8 et 12 mm, étant notamment de l'ordre de 10 mm. Pour conduire au panneau 1 selon la réalisation représentée, le procédé prévoit 30 en outre une étape consistant à disposer sous la couche de ouate 6, avant injection du mélange précurseur de mousse, une couche de matériau fibreux de renfort 8 de l'âme 2 destinée à être noyée dans la mousse, la face d'endroit 3 de ladite âme étant celle vers laquelle est disposée ladite couche de ouate.According to one embodiment, the wadding layer 6 has a thickness of between 8 and 12 mm before molding, being in particular of the order of 10 mm. In order to lead to the panel 1 according to the embodiment shown, the method furthermore provides a step of placing under the wadding layer 6, before injection of the precursor foam mixture, a layer of fibrous reinforcing material 8 of the core 2 intended to to be embedded in the foam, the location face 3 of said core being that towards which said layer of wadding is disposed.
3032375 5 Avec un tel agencement, on observe une suppression des défauts de surface en face d'endroit 3 et une bonne atténuation des défauts en face d'envers 4.With such an arrangement, it is observed a suppression of the surface defects in front of location 3 and a good attenuation of defects in front of back 4.
5 Selon une réalisation, la couche de matériau de renfort 8 est à base de fibres de verre. On décrit à présent un panneau 1 obtenu par un tel procédé, ledit panneau comprenant une âme 2 autoportante à base de mousse de polyuréthanne rigide 10 ou sem i rigide - ladite mousse présentant notamment une densité comprise entre 0,12 et 0,16, étant notamment de l'ordre de 0,14 -, ladite âme comprenant une face d'endroit 3 et une face d'envers 4, ledit panneau comprenant en outre une couche de revêtement d'endroit 5 collée sur ladite face d'endroit, ladite âme comprenant en outre une couche de ouate 6 noyée dans la mousse.In one embodiment, the layer of reinforcing material 8 is based on glass fibers. We now describe a panel 1 obtained by such a method, said panel comprising a core 2 self-supporting rigid polyurethane foam 10 or sem i rigid - said foam having a particular density between 0.12 and 0.16, being in particular of the order of 0.14 -, said core comprising a location face 3 and a back face 4, said panel further comprising a location coating layer 5 bonded to said location face, said core further comprising a wadding layer 6 embedded in the foam.
15 Selon la réalisation représentée, le panneau 1 comprend en outre une couche de revêtement d'envers 7 - notamment sous forme de non-tissé - collée en face d'envers 4 de l'âme 2.According to the embodiment shown, the panel 1 further comprises a backing layer 7 - in particular in the form of a nonwoven - bonded opposite the back 4 of the core 2.
20 Selon la réalisation représentée, l'âme 2 comprend en outre une couche de matériau fibreux de renfort 8 noyée dans la mousse, la couche de revêtement d'endroit 5 étant disposée du côté de la couche de ouate 6.According to the embodiment shown, the core 2 further comprises a fibrous reinforcing material layer 8 embedded in the foam, the location coating layer 5 being disposed on the side of the batting layer 6.
