Description
MATERIAU COMPOSITE D'ISOLATION ET D'ABSORPTION THERMIQUE
ET/OU PHONIQUE, ET SON PROCEDE DE FABRICATION
La présente invention concerne un matériau composite d'isolation et d'absorption thermique et/ou phonique, comportant une plaque d'un matériau thermiquement et/ou phoniquement isolant et absorbant et un support rigide solidaire d'une des faces de cette plaque.COMPOSITE MATERIAL FOR THERMAL INSULATION AND ABSORPTION
AND / OR PHONIC, AND ITS MANUFACTURING METHOD
The present invention relates to a composite insulation and thermal and / or sound absorption material, comprising a plate of a thermally and / or phonically insulating and absorbent material and a rigid support integral with one of the faces of this plate.
Elle concerne également un procédé de fabrication de ce matériau composite.It also relates to a process for manufacturing this composite material.
La plupart des caissons utilisés comme cabines de peinture, ateliers mobiles, caissons de ventilation et de traitement d'air, salles blanches ou chambres stériles, voire bureaux d'appoint, etc... , sont réalisés au moyen de cloisons isolantes comportant habituellement, au moins une couche de laine de verre ou de laine de roche maintenue entre deux plaques de tôle. Pour des réalisations plus sophistiquées où les parois doivent être isolées à la fois thermiquement et phoniquement, celles-ci se composent généralement d'une plaque de protection en tôle disposée à l'extérieur, revêtue intérieurement d'une masse lourde généralement constituée par une feuille de PVC, d'une première couche en laine de verre, d'une seconde couche en laine de roche et d'une feuille support rigide constituée par une plaque de tôle perforée formant la cloison intérieure.Most of the boxes used as paint booths, mobile workshops, ventilation and air treatment boxes, clean rooms or sterile rooms, even auxiliary offices, etc., are made by means of insulating partitions usually comprising, at least one layer of glass wool or rock wool held between two sheets of sheet metal. For more sophisticated embodiments where the walls must be insulated both thermally and phonically, these generally consist of a protective sheet metal plate placed outside, internally coated with a heavy mass generally consisting of a sheet PVC, a first layer of glass wool, a second layer of rock wool and a rigid support sheet formed by a perforated sheet plate forming the interior partition.
Ce type de matériau composite est très couramment utilisé, mais présente de multiples inconvénients, notamment son poids et le prix de sa fabrication. En effet, la présence d'une plaque de tôle perforée, qui constitue un matériau particulièrement coûteux, représente un inconvénient majeur de ce matériau. En outre, la présence de cette plaque de tôle perforée ainsi que celle de la laine de roche, qui constitue la couche de matériau phoniquement isolant, rendent ce matériau lourd et peu maniable. This type of composite material is very commonly used, but has multiple drawbacks, in particular its weight and the price of its manufacture. Indeed, the presence of a perforated sheet plate, which constitutes a particularly expensive material, represents a major drawback of this material. In addition, the presence of this perforated sheet plate as well as that of rock wool, which constitutes the layer of sound-insulating material, make this material heavy and difficult to handle.
La présente invention se propose de pallier ces inconvénients en réalisant un matériau composite relativement léger et de fabrication particulièrement économique.The present invention proposes to overcome these drawbacks by producing a relatively light composite material and of particularly economical manufacture.
Dans ce but, le matériau composite selon l'invention est caractérisé en ce que la plaque de matériau thermiquement et/ou phoniquement isolant et absorbant est une mousse synthétique et en ce que le support rigide est constitué par un grillage.For this purpose, the composite material according to the invention is characterized in that the plate of thermally and / or phonically insulating and absorbent material is a synthetic foam and in that the rigid support is constituted by a mesh.
Selon un mode de réalisation particulièrement avantageux, la plaque de matériau thermiquement et/ou phoniquement isolant et absorbant comporte deux couches de mousses synthétiques, séparées par une masse lourde constituée par une feuille d'un matériau dont la densité est supérieure à celle des mousses synthétiques.According to a particularly advantageous embodiment, the plate of thermally and / or phonically insulating and absorbent material comprises two layers of synthetic foams, separated by a heavy mass consisting of a sheet of a material whose density is greater than that of synthetic foams .
Les couches de mousses synthétiques sont avantageusement composées d'au moins un des matériaux suivants : polyuréthane, polyether, polyester et/ou l'un des dérivés de ces matériaux.The layers of synthetic foams are advantageously composed of at least one of the following materials: polyurethane, polyether, polyester and / or one of the derivatives of these materials.
Selon un mode de réalisation particulièrement intéressant, la masse lourde est constituée par une feuille en matière synthétique.According to a particularly interesting embodiment, the heavy mass consists of a sheet of synthetic material.
La masse lourde peut être composée d'une ou plusieurs feuilles en PVC, qui peut être chargé de sulfate de baryum.The heavy mass can be composed of one or more PVC sheets, which can be loaded with barium sulfate.
Selon un mode de réalisation préféré, le grillage est métallique.According to a preferred embodiment, the mesh is metallic.
Toutefois, ce grillage peut également être réalisé en une matière synthétique.However, this mesh can also be made of a synthetic material.
Selon une première forme de réalisation, le grillage est collé contre une face de la plaque de mousse synthétique.According to a first embodiment, the mesh is glued against one face of the synthetic foam plate.
Selon une autre forme de réalisation, le grillage est soudé contre une face de la plaque de mousse synthétique. According to another embodiment, the mesh is welded against one face of the synthetic foam plate.
Selon un mode réalisation particulièrement intéressant, le grillage est incorporé dans une couche superficielle adjacente à l'une des faces de la plaque de mousse synthétique, au moyen d'un traitement thermique.According to a particularly advantageous embodiment, the mesh is incorporated in a surface layer adjacent to one of the faces of the synthetic foam plate, by means of a heat treatment.
Pour la réalisation de parois, le matériau composite selon l'invention comporte de préférence au moins deux couches de mousses synthétiques, thermiquement et/ou phoniquement isolantes, séparées par une masse lourde composée d'au moins une feuille d'un matériau de densité supérieure à celle des mousses synthétiques, un film d'une substance adhésive solidaire de la face libre d'une des couches en mousse synthétique, et un grillage solidaire de la face libre de l'autre couche de mousses synthétiques.For the production of walls, the composite material according to the invention preferably comprises at least two layers of synthetic foams, thermally and / or phonically insulating, separated by a heavy mass composed of at least one sheet of a material of higher density. to that of synthetic foams, a film of an adhesive substance secured to the free face of one of the layers of synthetic foam, and a mesh secured to the free face of the other layer of synthetic foams.
Le procédé de fabrication du matériau composite selon l'invention, est caractérisé en ce que l'on incorpore le grillage dans une couche superficielle adjacente à l'une des faces de la plaque de mousse synthétique en effectuant un traitement thermique simultané du grillage et de la surface de ladite plaque de mousse synthétique.The method of manufacturing the composite material according to the invention is characterized in that the mesh is incorporated in a surface layer adjacent to one of the faces of the synthetic foam plate by performing a simultaneous heat treatment of the mesh and the surface of said synthetic foam plate.
La présente invention sera mieux comprise en référence à la description de différentes réalisations et au dessin annexé, dans lequel
La figure I représente une vue en perspective d'une première forme de réalisation du matériau selon l'invention,
La figure 2 représente une vue en perspective d'une forme de réalisation préférée du matériau selon l'invention, et
La figure 3 représente une vue en perspective d'une variante du matériau illustrée par la figure 2.The present invention will be better understood with reference to the description of various embodiments and to the accompanying drawing, in which
FIG. 1 represents a perspective view of a first embodiment of the material according to the invention,
FIG. 2 represents a perspective view of a preferred embodiment of the material according to the invention, and
FIG. 3 represents a perspective view of a variant of the material illustrated in FIG. 2.
La figure 1 représente une première forme de réalisation du matériau composite selon l'invention, composée dans ce cas d'une plaque 10 d'un matériau thermiquement et phoniquement isolant et absorbant d'un support rigide 11 solidaire de l'une des faces de cette plaque et d'une masse lourde 12 solidaire de l'autre face de la plaque 10. La couche extérieure de la masse lourde 12 est de préférence enduite d'un film 13 d'une substance adhésive qui facilite la mise en place et le maintien du matériau composite entre une paroi fixe 14, par exemple, constituée par une plaque en tôle.FIG. 1 represents a first embodiment of the composite material according to the invention, in this case composed of a plate 10 of a thermally and phonically insulating and absorbent material of a rigid support 11 secured to one of the faces of this plate and a heavy mass 12 secured to the other face of the plate 10. The outer layer of the heavy mass 12 is preferably coated with a film 13 of an adhesive substance which facilitates the positioning and holding the composite material between a fixed wall 14, for example, constituted by a sheet metal plate.
La plaque de matériau thermiquement et/ou phoniquement isolant et absorbant 10 est de préférence constituée par une mousse synthétique telle que par exemple une mousse de polyether, une mousse de polyester ou une mousse de polyuréthane ou l'un des dérivés de ces substances. Le support rigide 11 est constitué par un grillage qui peut être métallique (acier, aluminium, acier inoxydable) ou en un matériau synthétique rigide ou semi-rigide. Dans l'exemple représenté, ce grillage est collé contre la face intérieure de la plaque de mousses synthétiques 10.The plate of thermally and / or phonically insulating and absorbent material 10 is preferably constituted by a synthetic foam such as for example a polyether foam, a polyester foam or a polyurethane foam or one of the derivatives of these substances. The rigid support 11 is constituted by a mesh which may be metallic (steel, aluminum, stainless steel) or in a rigid or semi-rigid synthetic material. In the example shown, this mesh is glued against the inner face of the synthetic foam plate 10.
On notera que la masse lourde 12, de préférence réalisée en PVC chargé de sulfate de baryum, ou en tout autre matériau synthétique ou minéral ayant des propriétés analogues, n'est pas obligatoire, cette masse lourde est avantageusement constituée par un matériau ininflammable classé Ml. En effet, la plaque de mousses synthétiques 10 pourrait pour certaines utilisations, être directement collée sur la paroi rigide 14.Note that the heavy mass 12, preferably made of PVC loaded with barium sulphate, or any other synthetic or mineral material having similar properties, is not compulsory, this heavy mass is advantageously constituted by a non-flammable material classified as Ml . In fact, the synthetic foam plate 10 could, for certain uses, be directly glued to the rigid wall 14.
La figure 2 représente une autre forme de réalisation du matériau composite selon l'invention. Dans cet exemple, la plaque de matériau thermiquement et/ou phoniquement isolant et absorbant 10 se compose de deux plaques 10a et 1 Ob de mousses synthétiques qui peuvent être identiques ou différentes. Ces deux plaques de mousses synthétiques sont séparées par une masse lourde 12 constituée, par exemple d'une feuille en PVC chargé de sulfate de baryum. Toutefois, on notera que cette masse lourde dont le rôle est essentiellement de former un écran thermique et phonique n'est pas absolument indispensable si l'on se contente d'utiliser le matériau composite comme isolant thermique. FIG. 2 represents another embodiment of the composite material according to the invention. In this example, the plate of thermally and / or phonically insulating and absorbent material 10 consists of two plates 10a and 1 Ob of synthetic foams which may be identical or different. These two synthetic foam plates are separated by a heavy mass 12 consisting, for example of a PVC sheet loaded with barium sulfate. However, it will be noted that this heavy mass, the role of which is essentially to form a heat and sound barrier, is not absolutely essential if one is content to use the composite material as thermal insulator.
La plaque de matériau thermiquement et/ou phoniquement isolant 10 comporte avantageusement un film adhésif 13 qui permet la mise en place du matériau composite décrit contre une cloison 14, qui peut être une plaque de tôle ou tout autre matériau rigide.The plate of thermally and / or phonically insulating material 10 advantageously comprises an adhesive film 13 which allows the positioning of the composite material described against a partition 14, which can be a sheet metal plate or any other rigid material.
Sur sa face intérieure, la plaque d'isolation 10 est équipée d'un grillage 11, de préférence collé directement contre la surface de la mousse synthétique 1 osa. On its inner face, the insulation plate 10 is equipped with a mesh 11, preferably glued directly against the surface of the synthetic foam 1 osa.
Comme précédemment, le grillage peut être métallique ou réalisé en un matériau synthétique tel que le PVC, etc....As before, the mesh can be metallic or made of a synthetic material such as PVC, etc.
La figure 3 représente une variante du matériau composite illustré par la figure 2. Cet exemple de réalisation comporte comme précédemment une plaque 10 de matériau thermiquement et/ou phoniquement isolant comprenant deux couches 10a et 10b de mousses synthétiques séparées par une masse lourde 12 et collées au moyen d'un film adhésif 13 sur une plaque de tôle 14. Un grillage 11 est incorporé dans la couche superficielle de la plaque 10a de mousse synthétique. Cette incrustation de le grillage 11, de préférence métallique, s'effectue au moyen d'un traitement thermique simultané de la surface de la mousse synthétique et du grillage 11. Comme le montre la partie inférieure de la figure, la mousse synthétique 15 forme une peau lisse ou rugueuse qui recouvre quasi totalement le grillage 11 qui se trouve inscrusté dans la masse de la mousse synthétique. Cette solution est avantageuse en ce qu'elle permet d'escamoter le support rigide constitué par le grillage Il. FIG. 3 represents a variant of the composite material illustrated by FIG. 2. This exemplary embodiment comprises, as previously, a plate 10 of thermally and / or phonically insulating material comprising two layers 10a and 10b of synthetic foams separated by a heavy mass 12 and bonded by means of an adhesive film 13 on a sheet metal plate 14. A mesh 11 is incorporated in the surface layer of the plate 10a of synthetic foam. This inlaying of the mesh 11, preferably metallic, is carried out by means of a simultaneous heat treatment of the surface of the synthetic foam and of the mesh 11. As shown in the lower part of the figure, the synthetic foam 15 forms a smooth or rough skin which almost completely covers the mesh 11 which is embedded in the mass of the synthetic foam. This solution is advantageous in that it makes it possible to retract the rigid support constituted by the mesh II.
La présente invention n'est pas limitée aux formes de réalisations décrites, mais pourrait subir différentes modifications et se présenter sous diverses variantes évidentes pour l'homme de l'art. En particulier, le nombre des plaques de mousses synthétiques n'est pas limitée à deux. La forme des grillages peut être différente selon les applications visées. Le choix des matériaux utilisés pour réaliser ce matériau composite pourrait être élargi. The present invention is not limited to the embodiments described, but could undergo different modifications and come in various variants obvious to those skilled in the art. In particular, the number of synthetic foam sheets is not limited to two. The shape of the grids can be different depending on the intended applications. The choice of materials used to make this composite material could be widened.
