Abstract

Interior trimmings for automobile vehicles partic. for roofings, comprising a coating which is migration proof relative to organic prods., according to the parent patent, are characterised in the patent of addition in having the migration- proof coating placed between the decorative surface layer and the insulating rigid support layer. The coating comprises a film having good thermobonding properties on both its surfaces and which does not tend to creep at the forming temp. of the trimming. Specifically, the film is of polyester coated on both surfaces with a polyurethane or epoxy resin or the film is of polyurethane resin. The film acts as a barrier and prevents migration of resin binder used for consolidating the felt support, to the decorative surface layer. The entire trimming can be produced in one moulding step.

Description

La présente addition concerne une application du revêtement selon le brevet principal à la réalisation de garnitures intérioures de véhicules automobiles et notament de pavillons étanches aux migrations de produits organiques et le procédé de fabrication de ces garnitures. The present addition relates to an application of the coating according to the main patent for the production of interior trim for motor vehicles and in particular for pavilions that are impervious to the migration of organic products and the method of manufacturing these linings.

Le revêtement étanche aux migrations de produits orgeniques décruit au brovet prin eipal est caractérisé par la présence, notemment ontre la conche dorsale et la couche d'usure, d'une couche barrière constituée d'une matière chimiquement inerte vis-à-vis des produits organiques dent on vent empêcher la migration. The migration-tight coating of organic products described on the main eipal brovet is characterized by the presence, notably between the back protector and the wear layer, of a barrier layer made of a material chemically inert towards the products. organic teeth are prevented from migrating.

Ce preblème de la migration des preduits organioues se rencontre également dons le denaine des revêtements spécifiques que sont les garanitures intérieures de véhioules automobiles et plus spécialement les garnitures de pavillons. This problem of the migration of organic products is also encountered in the last of the specific coatings that are the interior garments of motor vehicles and more particularly the trim of pavilions.

Ces garnitures sont généralement coustituées de doux éléments rendus solidaires par collage : une couche décor, rolativement mince formant la surface de la garniture de une sous-couche isclante et de rembourrage, qui sert de support rigide après sa consolidation et qui, dans la majoure partie des cas, est formée d'un feutre de fibres de récupération lié par une résine thermockureissable, type résine phénolique. These linings are generally coustitués of soft elements made integral by gluing: a decorative layer, rolatively thin forming the surface of the lining of an insulating underlay and padding, which serves as a rigid support after its consolidation and which, in the majoure part of the cases, is formed from a felt of recovered fibers bonded by a thermo-curable resin, type phenolic resin.

On utilisera pour cette opération, du feutre non polymérisé afin de pouvoir le thermoformer en assurant sa consolidation. Dans une première opération, en préferme, dans un moule chauffé, la seus-couche isolatute liée par poudre de résine thermodurcissable ; on assure ains une coudensation de la résine consolidant les fibres. For this operation, non-polymerized felt will be used in order to be able to thermoform it while ensuring its consolidation. In a first operation, in the first place, in a heated mold, the isolatute layer linked by powder of thermosetting resin; this ensures a coudensation of the resin consolidating the fibers.

Dans une deuxième étape, cette sous-couche préformée, dont la face supérieure a été enduite de colle, est placée dans un moule, recouverte de la couche décor, puis l'ensemble est soumis à une opération de thermoformage sous pression, ce qui condense la résine, assure la solidarisation des deux couches et la rigidification de l'ensemble.  In a second step, this preformed sublayer, the upper face of which has been coated with glue, is placed in a mold, covered with the decor layer, then the assembly is subjected to a pressurized thermoforming operation, which condenses the resin, ensures the joining of the two layers and the stiffening of the whole.

I1 s'agit donc là d'un procédé long et coûtoux ; il n'a pas été possible jusqu'à maintenant d'envisager d'offectuer l'ensemble des opérations décrites ci-dessus on une seule étape, c'est-à-dire de procéder à un traitement unique de thermoformage sous pression de la sous-couche isolante liée par la résine non précondensée ou très légèrement précondensée et de la couche décor, ceci en raison de la migration, au moment du traitement thermique, des nombreux éléments organiques contenus dans la sous-couche isolante : produits de dégradation de la ré- sine utilisées plastifiants, huiles d'ensimage, colorants sublimables contenus dans les fibres, etc... t cette migration se traduit par de nombreuses taches sur la couche décor nuisant à ltaspect de la garniture. This is therefore a long and costly process; Until now, it has not been possible to envisage carrying out all of the operations described above in a single step, that is to say to carry out a single thermoforming treatment under pressure of the insulating sublayer bonded by the non-pre-condensed or very slightly pre-condensed resin and the decorative layer, this due to the migration, during the heat treatment, of the numerous organic elements contained in the insulating sub-layer: degradation products resin used plasticizers, sizing oils, sublimable dyes contained in the fibers, etc. t this migration results in numerous stains on the decor layer detracting from the appearance of the filling.

La présente addition vise à remédier à ces inconvé- nients, et en particulier à permettre de réaliser, en une seule opération, le thermoformage et la solidarisation de l'ensemble des éléments constituant la garniture inté- rieure. The present addition aims to remedy these drawbacks, and in particular to make it possible to carry out, in a single operation, thermoforming and the joining together of all the elements constituting the inner lining.

C'est ainsi qu'elle a pour objet une application du revêtement étanche aux migrations de produits organiques decrit au brevet principal à la réalisation de garnitures intérieures de véhicules automobiles et notamment de pavillons, qui comportent, entre la couche décor et la sous-couche isolante servant de support rigide, une couche barrière continue constituée d'une matière insensible à la migration de produits organiques. Thus it has for its object an application of the migration-tight coating of organic products described in the main patent for the production of interior trim for motor vehicles and in particular for flags, which comprise, between the decor layer and the under layer insulating serving as rigid support, a continuous barrier layer made of a material insensitive to the migration of organic products.

La couche barrière continue est avantageusement constituée d'un film possedant sur ses deux faces une bonne aptitude au thermocollage et ne présentant pas de tendance au fluage à la température de formage de l'ensem- ble du revêtement constituant la garniture intérieure. The continuous barrier layer is advantageously made up of a film having on its two faces a good heat-bonding ability and showing no tendency to creep at the forming temperature of the whole of the coating constituting the interior lining.

C'est ainsi que la couche barrière peut être constituée e d'un film de polyester et tout particulièrement de téréphtalate de polyéthylène glycol revêtu sur ses deux faces d'une enduction thermocollante à base de résines polyuréthane,époxy, acrylique, copolymère/maléate, ou de toute autre résine susceptible de communiquer au film une aptitude au thermocollage aux tempe ratures utilisées pour le formage de l'ensemble. Thus, the barrier layer can be made of a polyester film and very particularly of polyethylene glycol terephthalate coated on both sides with a heat-bonding coating based on polyurethane, epoxy, acrylic, copolymer / maleate resins, or any other resin capable of imparting to the film an ability to heat-bond at temperatures used for forming the assembly.

Elle peut être également constituée d'un film de té- trafluoréthylène revêtu sur ses deux faces d'une enduction thermocollante du type décrit ci-dessus. It can also consist of a tetrafluoroethylene film coated on both sides with a heat-bonding coating of the type described above.

Selon un autre mode de réalisation de l'invention, la couche barrière est constîtue'e d'un film présentant par lui-même une aptitude au thermocollage9 tel qu'un film de polyuréthane ou de tout autre matière thermoplastique dont le fluage à chaud est compatible avec la tempe rature de thermoformage. According to another embodiment of the invention, the barrier layer is made up of a film having by itself an ability to heat-bonding 9 such as a film of polyurethane or any other thermoplastic material whose hot creep is compatible with thermoforming temperature.

L'invention concerne également un procédé de fabrica tion des garnitures intérieures pour automobiles comportant une couche barrière continue constituée d'une ma- tiere étanche à la migration de produits organiques. The invention also relates to a method of manufacturing interior trim for automobiles comprising a continuous barrier layer made of a material which is impermeable to the migration of organic products.

Ce procédé consiste à placer successivement dans un moule a la forme de la garniture a réaliser et susceptible d'être chauffé, une couche décor mince, un film barrière thermocollant sur ses deux faces et étanche aux migrations de produits organiques et une sous-couche épaisse concti- tuée de préférence d'un mélange de fibres et de résine non polymérisée, å appliquer sur le moule une pression et une température donnée, pendant une durée suffisante pour assurer la condensation de la résine, la solidarisation des éléments constituant la garniture et la mise en forme de ladite garniture, puis à démouler la garniture rigide ainsi obtenue. This process consists in successively placing in a mold in the shape of the lining to be produced and capable of being heated, a thin decorative layer, a heat-bonding barrier film on its two faces and impermeable to the migration of organic products and a thick undercoat. preferably made of a mixture of fibers and unpolymerized resin, to apply to the mold a pressure and a given temperature, for a sufficient time to ensure the condensation of the resin, the joining of the elements constituting the lining and the shaping of said lining, then demolding the rigid lining thus obtained.

Selon un autre mode de réalisation, on place succes- sivement dans un moule à la forme de la garniture å réa- liser et susceptible d'être chauffe une sous-couche e'- paisse constituée de préférence d'un mélange de fibres et de résine non polymérisée, un film barrière thermocollant sur ses deux faces et étanche aux migrations de produits organiques, et une couche décor mince, et on répète les opérations comme mentionné ci-dessus. According to another embodiment, a thick undercoat, preferably made of a mixture of fibers and fibers, is successively placed in a mold in the shape of the filling to be produced and capable of being heated. non-polymerized resin, a heat-bonding barrier film on its two faces and impermeable to the migration of organic products, and a thin decorative layer, and the operations are repeated as mentioned above.

L'exemple suivant décrivant un mode de réalisation du du procéde d'obtention en une étape unique des garnitures intérieures selon la présente addition illustrera bien l'invention sans toutefois la limiter. The following example describing an embodiment of the process for obtaining interior fittings according to the present addition in a single step will illustrate the invention well without however limiting it.

On place successivement dans un moule chauffé, à la forme de la garniture que l'on désire obtenir
- une nappe de surface formant décor constituée d'un
non-tissé en fibres de polyester d'un poids au m2
de 120 à 200 g, dont la face au contact de la paroi
du moule peut éventuellement être imprimée et/ou
gaufrée,
- un film barrière continu, étanche aux migrations de
produits organiques. Dans le présent exemple, il
s'agit d'un film de polyester téréphtalate de po
lyéthylène glycol de 18 à 25 microns d'épaisseur,
dont chaque face est revêtue d'une enduction ther
mocollante de résine polyuréthane de 10 à 25 g/m2.We place successively in a heated mold, in the shape of the filling that we want
- a surface sheet forming a decoration consisting of a
polyester fiber fleece with a weight per m2
from 120 to 200 g, with the face in contact with the wall
of the mold can optionally be printed and / or
embossed,
- a continuous barrier film, impermeable to migration of
organic products. In this example, it
this is a poly terephthalate polyester film
lyethylene glycol from 18 to 25 microns thick,
each side of which is coated with a ther coating
polyurethane resin adhesive from 10 to 25 g / m2.

Ce film permet d'obtenir d'excellents résultats car
il joint a son excellente étanchéité aux migrations
de produits organiques, une très bonne aptitude au
thermocollage et un très faible fluage aux tempéra-
tures de traitement,
- une sous-couche d'envers qui est un feutre dont le
poids au m2 peut varier de 500 à 2000 g et qui est
constitué de fibres de récupération mélangées à
une poudre de résine formophénolique non condensée.This film achieves excellent results because
it joins its excellent tightness to migrations
organic products, very good
heat bonding and very low creep at temperatures
processing tures,
- a backing layer which is a felt whose
weight per m2 can vary from 500 to 2000 g and which is
made of recovered fibers mixed with
an uncondensed formophenolic resin powder.

On applique sur le moule revêtu de ces trois couches une pression de l'ordre de 5 kg/m, à une température de 180 à 2200C pendant 2 à 4 minutes, puis on démoule la garniture obtenue, qui a alors acquis sa forme définitive ainsi qu'une excellente rigidité due à la condensation de la résine formophônolique dans les fibres constituant la sous-couche. A pressure of the order of 5 kg / m is applied to the mold coated with these three layers, at a temperature of 180 to 2200C for 2 to 4 minutes, then the resulting packing is removed from the mold, which then acquired its final shape as well an excellent rigidity due to the condensation of the formophonolic resin in the fibers constituting the undercoat.

La même opération renouvelée en plaçant d'abord dans le moule chauffé la sous-couche d'envers puis le film bar rière continu, et enfin la couche décor donne également d'excellents résultats. The same operation repeated by first placing in the heated mold the backing layer then the continuous barrier film, and finally the decor layer also gives excellent results.

Les trois couches sont parfaitement solidaires et l'on ne constate aucune souillure de la nappe de surface du fait des impuretés dégagées par la sous-couche lors du traitement de thermoformage (orc8s dle résine formophénolique, plastifiants, huiles, colorants sublimables, etc...). The three layers are perfectly integral and there is no contamination of the surface layer due to the impurities released by the undercoat during the thermoforming treatment (orc8s dle formophenolic resin, plasticizers, oils, sublimable dyes, etc. .).

On peut renplacer le film de polyester de l'exemple ci-dessus par un film de polytétrafluoréthylène également muni sur ses deux faces d'une enduction thermocollante à base de résine polyuréthane ou de toute autre résine adap
tée à cet usage.The polyester film of the above example can be replaced by a polytetrafluoroethylene film also provided on both sides with a thermo-adhesive coating based on polyurethane resin or any other suitable resin.
for this purpose.

Solon l'état de surface tant de la couche décor que de la sous-couche isolante et rigidifiante, et spéciale ment Si elles ne comportent pas d'aspérités, on peut également ntiliser, comme couche barrière, un film intrinsèquement thermocollant, par exomple un film de polyuréthane, à condition qu'il reste, à la température de thermoformage, suffisament visqueux pour resteer à l'interface des deux couches, ne se déchire pas, et ne flue pas superfieiellement à l'intérieur de celles-ci
Dans le cas ou la résine emplcye'e pour assurer la liaison des fibres constituant la sous-couche isolante et de rigidification ne nécessite pas des températures de condensation aussi importantes que celles exigées par les résines formophénoliques classiques, on pent utiliser une couche barrière continue thermocollante à des températures plus basses, à condition toujours qu'elle soit parfaitement étanche aux migrations de produits organiques.Depending on the surface condition both of the decorative layer and of the insulating and stiffening sub-layer, and especially if they do not have any roughness, it is also possible to use, as barrier layer, an intrinsically fusible film, for example a polyurethane film, provided that it remains, at the thermoforming temperature, sufficiently viscous to remain at the interface of the two layers, does not tear, and does not creep superficially inside them
In the case where the resin emplcye'e to ensure the bonding of the fibers constituting the insulating and stiffening sub-layer does not require condensation temperatures as high as those required by conventional formophenolic resins, it is possible to use a continuous fusible barrier layer. at lower temperatures, always on the condition that it is perfectly impermeable to the migration of organic products.

Dans ce cas également, les enductions thermocollantes appliquées au film de polyester décrit dans l'exemple ci-dessus peuvent être réalisées avec des résines du type polyéthylène qui ne fluent pas aux tempo ratures de l'ordre de 100-1300C tout en présentant de bonnes propiétés de thermocollage a ces températures. In this case also, the fusible coatings applied to the polyester film described in the example above can be produced with resins of the polyethylene type which do not flow at temperatures of the order of 100-1300C while exhibiting good fusing properties at these temperatures.

Comme il va de soi, et comme il ressort de ce qui précède, la présente invention ne se limite pas au seul mode de réalisation décrit ci-dessus à titre d'exomple, elle en embrasse, au contraire, toutes les variantes de réalisation, quels que soient notanunent la nature des fibres constituant les non-tissés de la couche décor et de la couche isolante, la nature de la résine assurant la liaison et la rigidification des fibres de ladite souscouche et le mode de thermoformage de la garniture. As is obvious, and as appears from the above, the present invention is not limited to the single embodiment described above by way of example, it embraces, on the contrary, all the variant embodiments, whatever the nature of the fibers constituting the nonwovens of the decorative layer and of the insulating layer, the nature of the resin ensuring the bonding and stiffening of the fibers of said sublayer and the mode of thermoforming of the lining.
