Description

REVETEMENT DE MUR ET DE PLAFOND ET PROCEDE DE FABRICATION L’invention se rapporte à un revêtement pour mur et plafond qui comprend au moins un non tissé et/ou un tissu et au moins une couche d’une mousse ayant des propriétés d’isolation thermique, et à son procédé de fabrication.The invention relates to a wall and ceiling covering which comprises at least one nonwoven fabric and / or one fabric and at least one layer of a foam having thermal insulation properties. , and to its manufacturing process.

Les revêtements de mur et de plafond se répartissent en deux catégories : les non tissés (ou « intissés ») à base de cellulose, éventuellement associée à un polymère, notamment un polyester, qui comportent généralement des motifs structuraux obtenus par gaufrage, et les tissus de fibres naturelles ou artificielles, notamment en verre communément appelées « toiles à peindre ».Wall and ceiling coverings fall into two categories: non-woven (or "non-woven") based on cellulose, optionally associated with a polymer, in particular a polyester, which generally comprise structural motifs obtained by embossing, and fabrics natural or artificial fibers, in particular glass commonly known as "paintings to paint".

Les non tissés sont aisés à appliquer et sont peu coûteux. Leur fonction est essentiellement décorative : la diversité des motifs structuraux que l’on peut obtenir est très grande et en général les non tissés, notamment les papiers peints, ne requièrent aucun traitement après la pose tel que l’application d’une peinture.Nonwovens are easy to apply and are inexpensive. Their function is essentially decorative: the diversity of the structural patterns that can be obtained is very large and in general the nonwovens, especially the wallpapers, do not require any treatment after the application such as the application of a paint.

Les tissus de verre sont particulièrement avantageux. Ils possèdent d’excellentes propriétés mécaniques, notamment une résistance à l’abrasion élevée et une résistance à la traction importante qui leur permettent d’assurer la fonction de matériau de renforcement du support sur lequel ils sont appliqués. Les tissus de verre sont également imputrescibles et incombustibles.Glass fabrics are particularly advantageous. They have excellent mechanical properties, including high abrasion resistance and high tensile strength which enable them to perform the function of reinforcing material of the support to which they are applied. Glass fabrics are also rotproof and incombustible.

On connaît des revêtements muraux ou de plafond qui possèdent des propriétés d’isolation phonique.There are known wall or ceiling coverings which have sound insulation properties.

Dans US 4 283 457, le revêtement est une structure laminée qui comprend un mat de fibres de verre aiguilleté renforcé par une grille ou un tissu, tous deux constitués de fibres résistantes au feu, et un mat de fibres de verre ou une mousse à cellules ouvertes. La mousse est à base d’uréthane, de nitrile, de néoprène, de vinyle, de caoutchouc naturel, de styrène ou de styrène-butadiène. FR 2 932 499 divulgue un revêtement sous forme de lés qui comprend un tissu de revêtement, de préférence en verre textile, et une couche d’isolation acoustique formée d’un non tissé, d’un feutre ou d’une mousse, cette dernière couche pouvant être incluse dans un autre élément en nappe isolant phonique ou insonorisant.In US 4,283,457, the coating is a laminated structure which comprises a grid or fabric reinforced needled fiberglass mat, both made of fire-resistant fibers, and a fiberglass mat or a cell foam. open. The foam is based on urethane, nitrile, neoprene, vinyl, natural rubber, styrene or styrene-butadiene. FR 2 932 499 discloses a lined coating which comprises a covering fabric, preferably of textile glass, and an acoustic insulation layer formed of a nonwoven, a felt or a foam, the latter layer that can be included in another soundproof or sound insulating layer element.

La présente invention a pour but de fournir un revêtement mural et de plafond qui présente des propriétés d’isolation thermique, notamment qui possède une résistance thermique surfacique R qui varie de 0,3 à 1,5 m2.K/W.The present invention aims to provide a wall and ceiling covering which has thermal insulation properties, in particular which has a surface thermal resistance R which varies from 0.3 to 1.5 m2.K / W.

Pour atteindre ce but, il est proposé selon l’invention que la couche d’isolation thermique soit constituée d’une mousse de polyisocyanurate ou phénolique.To achieve this object, it is proposed according to the invention that the thermal insulation layer consists of a polyisocyanurate or phenolic foam.

Plus précisément, le revêtement mural et de plafond conforme à l’invention comprend au moins un non tissé et/ou un tissu et au moins une couche d’isolation thermique constituée d’une mousse de polyisocyanurate ou phénolique, le non tissé ou le tissu étant lié à la mousse par au moins une couche de colle.More specifically, the wall and ceiling covering according to the invention comprises at least one nonwoven and / or fabric and at least one thermal insulation layer consisting of a polyisocyanurate or phenolic foam, the nonwoven or the fabric being bonded to the foam by at least one layer of glue.

Le non tissé ou le tissu forment la face avant du revêtement mural et de plafond, c’est-à-dire la face visible après que le revêtement a été posé sur son support.The nonwoven or the fabric form the front face of the wall covering and ceiling, that is to say the visible side after the coating has been placed on its support.

Le non tissé et le tissu peuvent être constitués de fibres ou de fils organiques, par exemple de polyester, de cellulose, notamment de coton, de lin, de chanvre ou de sisal, ou de fibres ou de fils inorganiques, notamment de verre. L’épaisseur du non tissé et du tissu est généralement inférieure à 2 millimètres, de préférence inférieure à 1 millimètre.The nonwoven and the fabric may be made of organic fibers or yarns, for example polyester, cellulose, especially cotton, linen, hemp or sisal, or inorganic fibers or yarns, especially glass. The thickness of the nonwoven and the fabric is generally less than 2 millimeters, preferably less than 1 millimeter.

On préfère les tissus constitués de fils de verre destinés à être peints. Ces tissus sont avantageusement pourvus d’un d’apprêt qui a pour fonction de combler les ouvertures du tissu et réduire ainsi la quantité de peinture à appliquer par l’utilisateur final. L’apprêt est généralement une peinture aqueuse qui contient notamment des charges minérales à base d’oxyde de titane et/ou de carbonate de calcium.Tissues consisting of glass threads intended to be painted are preferred. These fabrics are advantageously provided with a primer whose function is to fill the openings of the fabric and thus reduce the amount of paint to be applied by the end user. The primer is generally an aqueous paint which contains in particular mineral fillers based on titanium oxide and / or calcium carbonate.

La couche d’isolation thermique est comme indiqué plus haut constituée d’une mousse de polyisocyanurate ou phénolique, par exemple une mousse phénol-formaldéhyde.The thermal insulation layer is as indicated above consisting of a polyisocyanurate or phenolic foam, for example a phenol-formaldehyde foam.

La mousse a une épaisseur qui varie de 10 à 50 millimètres, de préférence 10 à 30 millimètres.The foam has a thickness ranging from 10 to 50 millimeters, preferably 10 to 30 millimeters.

La mousse est choisie de telle sorte que la résistance thermique surfacique R du revêtement final varie de 0,3 à 1,5 m2.K/W.The foam is chosen so that the surface heat resistance R of the final coating varies from 0.3 to 1.5 m2.K / W.

La mousse est généralement rigide, et pour ce faire doit être incisée dans son épaisseur pour permettre un conditionnement sous la forme de rouleaux. La forme et la profondeur des incisions sont précisées plus loin.The foam is generally rigid, and to do this must be cut into its thickness to allow packaging in the form of rolls. The shape and depth of the incisions are specified below.

La mousse est liée au non tissé et/ou au tissu au moyen d’une colle aqueuse ou thermofusible. A titre d’exemples de colles aqueuses, on peut citer les colles contenant un polyuréthane, un acrylique, un méthacrylate d’alkyle, notamment de méthyle, un latex de polychlorure de vinyle (PVC), un polycarbonate, une polyoléfine telle qu’un polyéthylène ou un polypropylène, un epoxy ou un silicate. Les colles thermofusibles peuvent quant à elles renfermer les composés cités entrant dans la constitution des colles aqueuses, un copolymère de polyamide ou de polytéréphtalate d’éthylène (PET), ou un copolyester.The foam is bonded to the nonwoven and / or the fabric by means of an aqueous or hot-melt glue. As examples of aqueous adhesives, mention may be made of adhesives containing a polyurethane, an acrylic, an alkyl methacrylate, in particular methyl, a polyvinyl chloride (PVC) latex, a polycarbonate, a polyolefin such as a polyolefin. polyethylene or a polypropylene, an epoxy or a silicate. Hot melt adhesives can contain the compounds mentioned in the constitution of aqueous adhesives, a copolymer of polyamide or polyethylene terephthalate (PET), or a copolyester.

La colle peut contenir en outre des additifs, notamment des agents antifeu, par exemple des charges minérales telles que de l’hydroxyde d’aluminium AI(OH)3 ou de l’hydroxyde de magnésium Mg(OH)2, des composés azotés tels que la mélamine, et des composés phosphorés tels qu’un phosphate organique ou minéral, notamment un polyphosphate d’ammonium.The adhesive may also contain additives, in particular fireproofing agents, for example mineral fillers such as aluminum hydroxide Al (OH) 3 or magnesium hydroxide Mg (OH) 2, nitrogen compounds such as as melamine, and phosphorus compounds such as an organic or inorganic phosphate, especially an ammonium polyphosphate.

La quantité de colle à utiliser représente 1 à 35 % en masse de la masse totale du revêtement mural et de plafond, de préférence 2 à 25 %.The amount of glue to be used is 1 to 35% by weight of the total weight of the wall covering and ceiling, preferably 2 to 25%.

Le revêtement de mur et de plafond conforme à l’invention peut comprendre en outre une couche supplémentaire appliquée sur tout ou partie de la surface libre de la couche d’isolation thermique, c’est-à-dire la surface non liée au non tissé ou au tissu. La couche supplémentaire peut avoir une fonction visant à retarder le passage de l’eau (effet « barrière » à l’humidité) et/ou à améliorer l’adhérence au mur et au plafond. La couche supplémentaire peut se présenter sous la forme d’un non tissé ou d’un textile à base de fibres de verre et/ou de fibres cellulosiques. La couche supplémentaire présente une épaisseur généralement inférieure à 1 mm.The wall and ceiling covering according to the invention may further comprise an additional layer applied to all or part of the free surface of the thermal insulation layer, that is to say the unbonded nonwoven surface. or the fabric. The additional layer may have a function to delay the passage of water ("barrier" effect to moisture) and / or improve adhesion to the wall and ceiling. The additional layer may be in the form of a nonwoven or a textile based on glass fibers and / or cellulosic fibers. The additional layer has a thickness generally less than 1 mm.

Le revêtement de mur et de plafond conforme à l’invention peut aussi comprendre une couche complémentaire disposée entre le non tissé et/ou le tissu et la mousse, ladite couche complémentaire étant constituée d’un matériau qui contribue à améliorer la résistance au feu, par exemple l’aluminium.The wall and ceiling covering according to the invention may also comprise a complementary layer disposed between the nonwoven and / or the fabric and the foam, said complementary layer being made of a material which contributes to improving the fire resistance, for example aluminum.

Le procédé de fabrication du revêtement mural et de plafond constitue aussi un objet de l’invention. Le procédé comprend les étapes suivantes consistant à : - déposer en continu la mousse de polyisocyanurate ou phénolique sur un convoyeur, - appliquer une colle aqueuse ou thermofusibie sur la mousse, - chauffer à une température comprise entre 80 et 150°C lorsque la colle est thermofusibie, - déposer le non tissé et/ou le tissu sur la mousse enduite de colle, - faire passer l’ensemble dans l’entrefer d’au moins deux rouleaux caiandreurs, - inciser la mousse transversalement par rapport à la direction de défilement, et - collecter l’ensemble sous la forme d’un enroulement.The method of manufacturing the wall covering and ceiling is also an object of the invention. The process comprises the following steps: - continuously depositing the polyisocyanurate or phenolic foam on a conveyor, - applying an aqueous or thermofusibie adhesive on the foam, - heating at a temperature between 80 and 150 ° C when the adhesive is thermofusibie, - deposit the nonwoven fabric and / or the fabric on the foam coated with glue, - pass the assembly in the air gap of at least two rollers caiandreurs, - incise the foam transversely to the direction of scrolling, and - collect the assembly in the form of a winding.

La mousse de polyisocyanurate ou phénolique déposée sur le convoyeur se présente généralement sous la forme de plaques juxtaposées. L’application de la colle aqueuse est de préférence effectuée par pulvérisation. La colle thermofusibie peut se présenter sous la forme d’une poudre, d’un film, d’un voile, de fils ou d’une matière fondue. Le mode d’application de la colle thermofusibie peut être mis en oeuvre par tout moyen connu de l’homme du métier en fonction de la forme de la colle.The polyisocyanurate or phenolic foam deposited on the conveyor is generally in the form of juxtaposed plates. The application of the aqueous adhesive is preferably carried out by spraying. The hot-melt adhesive may be in the form of a powder, a film, a veil, thread or a melt. The method of application of the hot-melt glue can be implemented by any means known to those skilled in the art depending on the shape of the glue.

De préférence, la colle thermofusibie se présente sous la forme d’un voile ayant un grammage n’excédant pas 50 g/m2, avantageusement inférieur à 25 g/m2 et mieux encore qui varie de 12 à 20 g/m2.Preferably, the hotmelt adhesive is in the form of a web having a basis weight not exceeding 50 g / m 2, advantageously less than 25 g / m 2 and more preferably varying from 12 to 20 g / m 2.

La température de chauffage de la colle thermofusibie dépend de la nature chimique de la colle, du non tissé et/ou du tissu ainsi que de la mousse à assembler. La température doit être suffisante pour ramollir la colle mais rester inférieure à la température de fusion des éléments à assembler, notamment de la mousse. A la sortie des rouleaux caiandreurs, un dispositif de découpe permet de créer des incisions dans la mousse, transversalement par rapport à la direction de défilement, et à intervalles réguliers. La forme du dispositif de découpe détermine celle des incisions : les bords tranchants peuvent être parallèles créant ainsi des fentes, ou former un angle de quelques degrés permettant d’obtenir des incisions de section triangulaire dont la partie la plus étroite est située à proximité du non tissé ou du tissu. Les fentes sont préférées. La largeur des fentes est généralement inférieure à 5 millimètres.The heating temperature of the hot-melt glue depends on the chemical nature of the glue, the non-woven material and / or the fabric as well as the foam to be assembled. The temperature must be sufficient to soften the glue but remain below the melting temperature of the elements to be assembled, including foam. At the exit of the rollers, a cutting device makes it possible to create incisions in the foam, transversely with respect to the direction of travel, and at regular intervals. The shape of the cutting device determines that of the incisions: the cutting edges can be parallel, thus creating slots, or forming an angle of a few degrees to obtain incisions of triangular section whose narrowest part is located near the non woven or fabric. Slots are preferred. The width of the slots is generally less than 5 millimeters.

Les incisions peuvent avoir une profondeur qui correspond à l’épaisseur de la mousse, ou seulement une partie de celle-ci. Les incisions ayant une profondeur au moins égale à 90 % de l’épaisseur de la mousse sont préférées car elles permettent un meilleur enroulement du revêtement mural et de plafond.The incisions can have a depth that corresponds to the thickness of the foam, or only a part of it. Incisions having a depth of at least 90% of the thickness of the foam are preferred because they allow a better winding of the wall covering and ceiling.

Lorsque le revêtement mural et de plafond contient une couche supplémentaire, celle-ci est déposée en premier sur le convoyeur, en amont du dépôt de la mousse, et liée à la mousse au moyen d’une colle aqueuse ou thermofusibie de même nature que celle décrite précédemment, de préférence thermofusibie.When the wall and ceiling covering contains an additional layer, it is deposited first on the conveyor, upstream of the deposition of the foam, and bonded to the foam by means of an aqueous or thermofusibie adhesive of the same nature as that previously described, preferably thermofusibie.

De préférence, les bords latéraux du non tissé et/ou du tissu dépassent de la mousse ce qui permet lors de la pose finale de superposer les bords et de les découper de manière à obtenir un joint de très bonne qualité. La largeur des bords latéraux non liés à la mousse varie généralement de 1 à 5 cm.Preferably, the lateral edges of the nonwoven fabric and / or fabric protrude from the foam which allows during the final laying to superimpose the edges and to cut them so as to obtain a seal of very good quality. The width of the lateral edges not bound to the foam generally varies from 1 to 5 cm.

Les exemples qui suivent permettent d’illustrer l’invention sans toutefois la limiter. EXEMPLE 1The following examples illustrate the invention without limiting it. EXAMPLE 1
