Description
Domaine technique de l'inventionTechnical field of the invention
La présente invention concerne le domaine des panneaux pour l’isolation thermique et phonique et, plus particulièrement, des panneaux isolants à base de matériaux bio-sourcés respectueux de l’environnement.The present invention relates to the field of panels for thermal and sound insulation and, more particularly, insulating panels based on bio-sourced materials that respect the environment.
Etat de la techniqueState of the art
Dans le domaine des panneaux isolants (isolant pour l’enveloppe d’un bâtiment), il est connu d'utiliser des plaques d’isolation en polyuréthane et polyisocyanurate. Les inconvénients de ce type de plaques sont qu’elles sont constituées de matériaux qui ne respectent pas l’environnement et qu’elles ont des performances faibles en Eté. En effet, elles permettent de maintenir la chaleur à l’intérieur des bâtiments en Hiver mais en Eté, à la tombée de la nuit, lorsque la température extérieure devient inférieure à la température intérieure, ces plaques ne permettent pas aux bâtiments de se rafraîchir et leur utilisation impose donc souvent l’usage d’un système de climatisation intérieur, c’est ce que l’on appelle le déphasage. L’impact environnemental négatif de ce type d’isolation est donc double : l’utilisation d’un isolant pétro-sourcé de manière importante et la nécessité d’utiliser un dispositif de climatisation en Eté augmentent l’empreinte carbone.In the field of insulating panels (insulation for the envelope of a building), it is known to use polyurethane and polyisocyanurate insulation plates. The disadvantages of this type of plates are that they are made of materials that do not respect the environment and that they have poor performance in summer. Indeed, they make it possible to maintain the heat inside the buildings in Winter but in Summer, at nightfall, when the outside temperature becomes lower than the inside temperature, these plates do not allow the buildings to cool down and their use therefore often requires the use of an indoor air conditioning system, this is called phase shift. The negative environmental impact of this type of insulation is therefore twofold: the use of a significant petro-sourced insulation and the need to use an air conditioning system in summer increase the carbon footprint.
Le but de la présente invention est donc de pallier les inconvénients précédemment cités et de proposer un panneau et un procédé de fabrication d’un panneau isolant contenant plus de 50% de matériaux bio-sourcés plus respectueux de l’environnement et ayant un bon déphasage.The object of the present invention is therefore to overcome the drawbacks mentioned above and to propose a panel and a method of manufacturing an insulating panel containing more than 50% of bio-sourced materials that are more respectful of the environment and have a good phase shift. .
On désigne par « déphasage » la capacité d’un matériau composant l'enveloppe d’une habitation à ralentir la pénétration de la chaleur. Le déphasage permet donc de lisser les écarts de températures intérieures dus aux variations de températures extérieures.“Phase shift” refers to the ability of a material making up the envelope of a dwelling to slow down the penetration of heat. The phase shift therefore makes it possible to smooth out the differences in interior temperatures due to variations in exterior temperatures.
Conformément à l’invention, il est donc proposé un panneau isolant à base de matériaux composites, remarquable en ce qu’il comporte au moins:
- une couche comportant un mélange d’au moins un liant et de liège,
- une tôle métallique plane ou profilée.In accordance with the invention, there is therefore proposed an insulating panel based on composite materials, remarkable in that it comprises at least:
- a layer comprising a mixture of at least one binder and cork,
- a flat or profiled sheet metal.
On appelle « panneau » un assemblage composite formé d’un substrat (ici la tôle) recouvert d’une ou plusieurs couches d’un autre matériau ou mélange de matériaux.A “panel” is a composite assembly made up of a substrate (here sheet metal) covered with one or more layers of another material or mixture of materials.
On appelle « matériau composite » un assemblage d'au moins deux composants (matériaux) non miscibles (mais ayant une forte capacité de pénétration) dont les propriétés se complètent. Le nouveau matériau ainsi constitué, hétérogène, possède des propriétés que les composants seuls ne possèdent pas.A “composite material” is an assembly of at least two components (materials) that are not miscible (but have a high penetration capacity) whose properties complement each other. The new material thus formed, heterogeneous, has properties that the components alone do not have.
On appelle « liège », un matériau présent dans l'écorce de quelques arbres, et notamment dans celle du chêne-liège. Le terme « liège » désigne indifféremment le matériau sous sa forme brute ou prétraitée (les prétraitements sont les traitements effectués au liège brute pour permettre son utilisation dans le domaine de l’isolation par exemple).We call "cork", a material present in the bark of some trees, and in particular in that of the cork oak. The term "cork" refers to the material in its raw or pretreated form (pretreatments are the treatments carried out on raw cork to allow its use in the field of insulation, for example).
On appelle « tôle métallique plane » une feuille métallique laminée. A “flat metal sheet” is a rolled metal sheet .
On appelle « tôle métallique profilée » une feuille métallique fabriquée avec un profil déterminé (par exemple : une tôle métallique nervurée ou ondulée).The term "profiled sheet metal" refers to a sheet metal manufactured with a determined profile (for example: a ribbed or corrugated sheet metal).
On appelle « liant » un produit qui sert à agglomérer en masse solide des particules solides sous forme de poudre ou de granulats (par exemple, une colle).A “binder” is a product that serves to agglomerate solid particles in the form of powder or aggregates (for example, an adhesive) into a solid mass.
Avantageusement, la tôle métallique est une tôle en acier.Advantageously, the metal sheet is a steel sheet.
De manière préférée, le liant est un liant organique.Preferably, the binder is an organic binder.
On appelle liants « organiques », les liants hydrocarbonés à base de carbures d’hydrogène dont le durcissement est réversible et fonction de la température (ex : goudron, bitume) et les liants de type résine ou polymère.The term "organic" binders refers to hydrocarbon binders based on hydrogen carbides whose hardening is reversible and a function of temperature (e.g. tar, bitumen) and binders of the resin or polymer type.
De manière encore plus préférée, le liant est un polymère ou un mélange de polymères.Even more preferably, the binder is a polymer or a mixture of polymers.
Préférentiellement, le liant est un polyuréthane, un polyépoxyde, ou un non-isocyanate polyuréthane (NIPU).Preferably, the binder is a polyurethane, a polyepoxide, or a non-isocyanate polyurethane (NIPU).
Plus préférentiellement, le liant est un polyuréthane.More preferably, the binder is a polyurethane.
Encore plus préférentiellement, le liant est issu d’une réaction de polyaddition d’un polyisocyanate avec un polyol.Even more preferentially, the binder results from a polyaddition reaction of a polyisocyanate with a polyol.
De manière préférée, la couche comporte entre 20 et 80% en masse de liège et respectivement entre 80 et 20 % en masse de polyuréthane.Preferably, the layer comprises between 20 and 80% by mass of cork and respectively between 80 and 20% by mass of polyurethane.
De manière plus préférée, la couche comporte entre 35 et 65% en masse de liège et respectivement entre 65 et 35 % en masse de polyuréthane.More preferably, the layer comprises between 35 and 65% by mass of cork and respectively between 65 and 35% by mass of polyurethane.
De manière encore plus préférée, la couche comporte entre 45 et 55% en masse de liège et respectivement entre 55 et 45 % en masse de polyuréthane.Even more preferably, the layer comprises between 45 and 55% by mass of cork and respectively between 55 and 45% by mass of polyurethane.
Avantageusement, le liant est issu d’une réaction de polyaddition entre un diisocyanate et un polyol.Advantageously, the binder results from a polyaddition reaction between a diisocyanate and a polyol.
On désigne par « diisocyanate », une molécule ayant la structure suivante :The term "diisocyanate" denotes a molecule having the following structure:
avec R contenant des structures aliphatiques linéaires et cycliques et/ou des structures aromatiques (par exemple : MDI, HDI, TDI, HMDI, IPDI, LDI…)with R containing linear and cyclic aliphatic structures and/or aromatic structures (for example: MDI, HDI, TDI, HMDI, IPDI, LDI…)
ou issu de son auto-condensation avec R contenant par exemple des fonctions isocyanurates, biurée allophanates…, une fonctionnalité n=2 ou n >2, et une masse inférieure à 10000g.mol-1 or resulting from its self-condensation with R containing for example isocyanurate functions, allophanate biurea, etc., an n=2 or n >2 functionality, and a mass of less than 10000g.mol -1
ou issu de prépolymérisation d’un polyol en défaut avec un diisocyanate, une fonctionnalité n=2 ou n>2 et une masse inférieure à 10000g.mol-1 or resulting from prepolymerization of a polyol in default with a diisocyanate, an n=2 or n>2 functionality and a mass of less than 10000g.mol -1
Plus avantageusement, le liant est issu de la réaction de polyaddition entre un diisocyanate à base de 1,6-diisocyanatohexane contenant des fonctions allophanates et un polyol.More advantageously, the binder is derived from the polyaddition reaction between a diisocyanate based on 1,6-diisocyanatohexane containing allophanate functions and a polyol.
De manière plus avantageuse, le liant est issu d’une réaction de polyaddition entre un diisocyanate à base de 1,6-diisocyanatohexane contenant des fonctions allophanates et un diol choisi parmi les diols suivants : éthylène glycol ou 1,4-butanediol ou 1,3-propanediol.More advantageously, the binder results from a polyaddition reaction between a diisocyanate based on 1,6-diisocyanatohexane containing allophanate functions and a diol chosen from the following diols: ethylene glycol or 1,4-butanediol or 1, 3-propanediol.
De manière encore plus avantageuse, le liant est issu d’une réaction de polyaddition entre un diisocyanate à base de 1,6-diisocyanatohexane contenant des fonctions allophanates et le 1,3-propanediol.Even more advantageously, the binder results from a polyaddition reaction between a diisocyanate based on 1,6-diisocyanatohexane containing allophanate functions and 1,3-propanediol.
Préférentiellement, le liège est en poudre.Preferably, the cork is in powder form.
On appelle « poudre » de liège, un état dans lequel le liège est sous forme de morceaux de taille inférieure à 100 micromètres.We call "powder" of cork, a state in which the cork is in the form of pieces of size less than 100 micrometers.
L’invention concerne également un procédé de fabrication en continu d’un panneau isolant tel que décrit précédemment, remarquable en ce qu’il comporte au moins les étapes successives suivantes :
