PROCEDE DE FABRICATION D'UN MATERIAU ISOLANT A PARTIR DE DECHETS DE FIBRES, MATERIAU ISOLANT OBTENU La présente invention concerne un procédé de fabrication d'un matériau isolant à partir de déchets de fibres. L'invention couvre aussi le matériau isolant obtenu. On sait que de nombreux procédés de fabrication de produits en matériaux composites à partir de fibres génèrent des déchets. The present invention relates to a process for producing an insulating material from fiber waste. The invention also covers the insulating material obtained. It is known that many processes for manufacturing composite products from fibers generate waste.
En effet, ces procédés consistent à préparer des renforts à partir de mats de fibres de différentes natures, ces renforts étant destinés à être inclus dans des matrices de résines thermodurcissables ou thermoplastiques. Indeed, these methods consist in preparing reinforcements from mats of different types of fibers, these reinforcements being intended to be included in matrices of thermosetting or thermoplastic resins.
Ces renforts sont destinés à des pièces de formes particulières tandis que les mats de fibres sont fabriqués en continu et se présentent sous formes de 10 renforts en rouleaux de différentes largeurs. These reinforcements are intended for parts of particular shapes while the fiber mats are manufactured continuously and are in the form of reinforcements in rolls of different widths.
Ces renforts sont donc nécessairement découpés au profil de la pièce à réaliser, ce qui conduit à des chutes de matière. These reinforcements are necessarily cut to the profile of the part to be produced, which leads to material falls.
Cette matière, par exemple dans le cas de non tissés, comprend des fibres qui n'ont aucunement été souillées. This material, for example in the case of nonwovens, comprises fibers which have not been soiled.
Par contre, ces fibres sont de différentes longueurs, de différents diamètres et peuvent être regroupées si nécessaire en fonction de leur nature, fibres de verre, fibres naturelles par exemple. By cons, these fibers are of different lengths, different diameters and can be grouped if necessary depending on their nature, glass fibers, natural fibers for example.
Ces déchets sont un coût pour le produit final puisqu'il s'agit de chutes et ceci est la plupart du temps le cas pour les produits manufacturés. This waste is a cost for the final product because it is a waste and this is mostly the case for manufactured products.
Par contre, il y a un surcoût du fait de l'évacuation et de l'élimination de ces déchets. On the other hand, there is an additional cost due to the evacuation and disposal of this waste.
2887561 2 Comme ordre de grandeur, on peut citer des déchets composés de fibres de diamètres compris entre 5 et 30 pm et de longueur de 25 mm à plusieurs centimètres. As an order of magnitude, there may be mentioned wastes composed of fibers of diameters between 5 and 30 μm and length of 25 mm to several centimeters.
La fibre de verre est la plus utilisée dans les matériaux composites donc celle 5 que l'on retrouve en plus grande quantité sur le marché des déchets mais pas uniquement. Fiberglass is the most used in composite materials so that 5 is found in greater quantity in the waste market but not only.
On sait aussi que le marché de l'isolation, notamment dans le bâtiment, est à la recherche de matériaux de moins en moins chers afin de pouvoir isoler toutes les parties construites, générant des économies d'énergie. We also know that the insulation market, especially in the building industry, is looking for less and less expensive materials in order to insulate all the parts built, generating energy savings.
Le procédé de fabrication d'un matériau isolant selon la présente invention permet de recycler les déchets notamment immédiatement sur le lieu où les déchets sont générés si les quantités sont suffisantes, en faisant appel à des matériels existants mais utilisés ni dans la succession d'étapes revendiquée ni dans le but poursuivi dans la présente invention. The method of manufacturing an insulating material according to the present invention makes it possible to recycle the waste, especially immediately on the site where the waste is generated if the quantities are sufficient, using existing equipment but used or in the succession of steps. claimed or for the purpose of the present invention.
Le procédé est maintenant décrit selon un mode de réalisation particulier avec des variantes sans que ce procédé puisse être considéré comme limitatif. The method is now described according to a particular embodiment with variants without this method being considered as limiting.
Les fibres provenant de déchets sont placées dans une trémie avant d'être traitées par des moyens de cardage qui assurent une séparation et une orientation dans le sens longitudinal de ces fibres de façon à disposer de fibres parallèles les unes aux autres. Fibers from waste are placed in a hopper before being treated by carding means which provide separation and orientation in the longitudinal direction of these fibers so as to have fibers parallel to each other.
Ces fibres disposées principalement dans une même direction, celle du déplacement dans la chaîne de fabrication, sont ensuite déposées sur un premier tapis transporteur avec une épaisseur donnée. These fibers arranged mainly in the same direction, that of the displacement in the production line, are then deposited on a first conveyor belt with a given thickness.
Cette épaisseur est obtenue en fonction de la vitesse relative de ce tapis 25 transporteur et du volume de fibres unidirectionnelles déposé. This thickness is obtained as a function of the relative speed of this conveyor belt and the volume of unidirectional fibers deposited.
Le procédé prévoit de conférer à ce mat des propriétés mécaniques et dans ce but, soit il s'agit d'un procédé mécanique d'aiguilletage ou autres, uniquement 2887561 3 par travail mécanique soit il est prévu d'introduire un liant dans ce mat de fibres produit. The method provides for this mat to have mechanical properties and for this purpose, either it is a mechanical needling process or the like, only 2887561 3 by mechanical work or it is expected to introduce a binder in this mat of fiber produced.
Le procédé mécanique consiste à rapporter de façon régulière une ou plusieurs couche de fibres afin de lier les fibres issues de déchets et cette ou ces 5 couches de fibres de structure. The mechanical process consists in regularly reporting one or more layers of fibers in order to bind the waste fibers and this or these layers of structural fibers.
Une première voie d'introduction d'un liant consiste à introduire au sein des fibres issues de déchets un liant sous forme de fibres thermofusibles. Ces fibres thermofusibles sont choisies en fonction de la nature du matériau constituant les fibres de recyclage de façon à ce qu'elles assurent ultérieurement ainsi que cela va être décrit, la cohésion du mat. A first way of introducing a binder is to introduce into the fibers from waste a binder in the form of hot melt fibers. These hot melt fibers are chosen according to the nature of the material constituting the recycling fibers so that they subsequently provide, as will be described, the cohesion of the mat.
Ces fibres sont introduites à raison de taux de l'ordre de 10 à 20% pour donner un ordre d'idées. These fibers are introduced at a rate of the order of 10 to 20% to give an order of ideas.
Une autre voie consiste à inclure de la poudre de liant thermofusible au sein du mat de fibres unidirectionnelles. Another way is to include hot melt binder powder within the unidirectional fiber mat.
Une autre voie d'introduction d'un liant consiste à projeter un liant sur les fibres au moment de la dépose sur le premier tapis. Another way of introducing a binder is to project a binder on the fibers at the time of removal on the first carpet.
Dans tous les cas, il faut que le liant soit dispersé au sein du mat de façon homogène. In all cases, it is necessary that the binder is dispersed within the mat homogeneously.
En sortie de dépose des fibres, l'étape suivante consiste en une étape de chauffage du mat soit pour polymériser le liant déposé par projection, soit pour faire fondre et polymériser la poudre de liant thermofusible, soit encore pour faire fondre et polymériser les fibres thermofusibles introduites dans le mat. Le mat ainsi réalisé présente des épaisseurs de l'ordre de 5 à 300 mm, avec une densité de 10 à 200 g/m2. At the fiber removal outlet, the following step consists of a step of heating the mat either to polymerize the binder deposited by spraying, or to melt and polymerize the hot melt binder powder, or to melt and polymerize the hot melt fibers. introduced in the mat. The mat thus produced has thicknesses of the order of 5 to 300 mm, with a density of 10 to 200 g / m2.
Ce mat est ensuite mis en forme pour constituer le matériau isolant recherché. Cette mise en forme consiste à former des ondulations du mat de fibres liées tel que fabriqué. This mat is then shaped to form the desired insulating material. This shaping consists of forming corrugations of the mat of bound fibers as manufactured.
2887561 4 Ces ondulations présentent un angle compris entre 90 et 140 à 150 par rapport à l'horizontale. 2887561 4 These corrugations have an angle of between 90 and 140 to 150 relative to the horizontal.
La densité des ondulations est comprise entre 1 et 10 ondulations par centimètre linéaire. The density of the corrugations is between 1 and 10 ripples per linear centimeter.
Le but est de former un volume le plus important possible avec le moins possible de fibres de sorte à emprisonner un volume d'air très important qui est garant d'un fort pouvoir isolant. The goal is to form as large a volume as possible with as little fiber as possible so as to trap a very large volume of air which guarantees a high insulating power.
Ainsi le matériau obtenu présente un taux de 10 % maximum de fibres par unité de volume. Thus the material obtained has a rate of 10% maximum fibers per unit volume.
Il est ensuite possible de réaliser des complexes à partir de ce matériau. Ainsi, le produit final peut comporter plusieurs couches de matériau à fibres unidirectionnelles ondulées, superposées les unes sur les autres. It is then possible to make complexes from this material. Thus, the final product may comprise several layers of corrugated unidirectional fiber material superimposed on each other.
Ces couches peuvent être liées par tout moyen y compris par interposition d'un liant. These layers can be bonded by any means including interposition of a binder.
Ces couches peuvent être superposées qui plus est de façon croisée pour améliorer la résistance mécanique de l'ensemble. These layers can be superimposed moreover crosswise to improve the strength of the assembly.
En variante, sur une face du matériau isolant ondulé ainsi réalisé il peut être rapporté une feuille réflectrice en matériau métallique tel que de l'aluminium. La liaison est obtenue par exemple par collage. Ceci renforce l'effet isolant et permet aussi une manipulation plus aisée, notamment un conditionnement sous forme de rouleau. Alternatively, on one side of the corrugated insulating material thus produced may be reported a reflective sheet of metallic material such as aluminum. The bond is obtained for example by gluing. This enhances the insulating effect and also allows easier handling, including packaging in roll form.
Selon une autre variante, le matériau isolant ondulé peut porter deux feuilles de matériau métallique, une sur chaque face. L'invention prévoit aussi plusieurs feuilles métalliques interposées entre les couches si nécessaire pour réaliser des complexes sophistiqués. According to another variant, the corrugated insulating material may carry two sheets of metallic material, one on each face. The invention also provides several metal sheets interposed between the layers if necessary to achieve sophisticated complexes.
La feuille peut aussi être en matériau cellulosique tel que du papier kraft sur au moins une des faces. The sheet may also be of cellulosic material such as kraft paper on at least one of the faces.
Ce type de matériau présente un rôle de pare vapeur surtout s'il a subi un traitement hydrophobe par dépose d'une cire par exemple. This type of material has a role of vapor barrier especially if it has undergone a hydrophobic treatment by removal of a wax for example.
Le matériau ainsi obtenu présente de bonnes propriétés isolantes et permet une utilisation des fibres provenant des déchets de fabrication d'autres renforts, 5 évitant des recyclages inutiles et en assurant une valorisation. The material thus obtained has good insulating properties and makes it possible to use the fibers from the manufacturing waste of other reinforcements, avoiding unnecessary recycling and ensuring recovery.
