Description
ELEMENT COMPOSITE CONSTITUE D'UNE PLAQUE RIGIDE
ET DE LAINE DE VERRE
L'invention concerne un élément composite constitué d'une part d'une plaque rigide, telle qu'une plaque de plâtre et d'autre part d'un matelas de laine de verre, la plaque et le matelas étant par exemple collés l'un à l'autre.COMPOSITE ELEMENT CONSISTING OF A RIGID PLATE
AND GLASS WOOL
The invention relates to a composite element consisting on the one hand of a rigid plate, such as a plasterboard and on the other hand of a glass wool mat, the plate and the mat being for example glued together. to one another.
De tels éléments sont notamment utilisés pour doubler des murs ou cloisons et apporter une isolation thermique et une isolation acoustique. Lors de l'installation, ces éléments sont fixés, par exemple par collage, au mur ou à la cloison de façon à ce que la face visible soit la plaque de plâtre. Ladite plaque constitue alors une surface de parement pouvant supporter tout type de finition. Outre ses propriétés d'isolant acoustique, le matelas de laine de verre doit présenter des propriétés mécaniques et de tenue satisfaisantes, notamment du fait qu'il sert d'intermédiaire pour l'accrochage de la plaque de plâtre au mur ou à une cloison. II doit notamment présenter une bonne résistance à la compression ainsi qu'une bonne cohésion, c'est-à-dire une bonne résistance à l'arrachement.Such elements are used in particular for lining walls or partitions and providing thermal insulation and acoustic insulation. During installation, these elements are fixed, for example by gluing, to the wall or to the partition so that the visible face is the plasterboard. Said plate then constitutes a facing surface capable of withstanding any type of finish. In addition to its sound-insulating properties, the glass wool mattress must have satisfactory mechanical and resistance properties, in particular due to the fact that it serves as an intermediary for attaching the plasterboard to the wall or to a partition. It must in particular exhibit good compressive strength as well as good cohesion, that is to say good resistance to tearing.
De tels éléments ont déjà remportés un grand succès car ils présentent de nombreux avantages
O Tout d'abord ils se présentent sous forme de plaques et sont ainsi facilement transportables sur palette,
O D'autre part, en ce qui concerne leur pose, celle-ci est simple et rapide car elle se fait par collage,
O Par ailleurs, la surface obtenue directement après les travaux d'isolation est une surface pouvant supporter tout type de finition.Such elements have already been very successful because they have many advantages
O First of all, they come in the form of plates and are thus easily transportable on a pallet,
O On the other hand, when it comes to their installation, it is quick and easy because it is done by gluing,
O In addition, the surface obtained directly after the insulation work is a surface that can withstand any type of finish.
O Enfin, I'isolation, tant thermique qu'acoustique, obtenue est tout-à-fait satisfaisante. Finally, the insulation, both thermal and acoustic, obtained is completely satisfactory.
Toutefois, les auteurs de la présente invention se sont donnés pour mission de réaliser un tel élément dont le matelas de laine de verre présente une quantité de matière moindre, notamment en vue d'une diminution du coût, tout en conservant les propriétés précédemment énoncées. However, the authors of the present invention have given themselves the task of producing such an element, the glass wool mattress of which has a smaller quantity of material, in particular with a view to reducing the cost, while retaining the previously stated properties.
Ce but est atteint selon l'invention par la réalisation d'un élément composite constitué d'une plaque rigide et d'un matelas de laine de verre solidaires l'un de l'autre, le matelas de laine de verre étant constitué de fibres de verre réparties dans le matelas de façon tridimensionnelle. II s'est en effet avéré qu'un tel élément selon l'invention peut être réalisé avec une quantité moindre de matière, en ce qui concerne le matelas de laine de verre, tout en conservant les propriétés mécaniques d'une part et d'isolation thermoacoustique d'autre part. This object is achieved according to the invention by the production of a composite element consisting of a rigid plate and of a mat of glass wool integral with one another, the mat of glass wool consisting of fibers. of glass distributed in the mattress in a three-dimensional way. It has in fact turned out that such an element according to the invention can be produced with a smaller amount of material, as regards the glass wool mat, while retaining the mechanical properties on the one hand and on the other hand. thermoacoustic insulation on the other hand.
Les fibres de verre, constituant le matelas de laine de verre sont avantageusement produites par un procédé centrifuge interne. The glass fibers constituting the glass wool mat are advantageously produced by an internal centrifugal process.
Un tel élément selon l'invention présente avantageusement une masse volumique inférieure à 60 kg/m3. De préférence, cette masse volumique est inférieure à 55 kg/m3 et de préférence encore supérieure à 40 kg/m3. Such an element according to the invention advantageously has a density of less than 60 kg / m 3. Preferably, this density is less than 55 kg / m 3 and more preferably more than 40 kg / m 3.
Les inventeurs interprètent la possibilité de pouvoir diminuer la quantité de matière comme étant directement liée à la répartition tridimensionnelle des fibres dans le matelas de laine de verre. En effet, il semble qu'une telle répartition autorise la réalisation d'un matelas comportant moins de matière et présentant des propriétés mécaniques similaires à un matelas de laine de verre classique. Ces propriétés mécaniques sont plus particulièrement la résistance à la compression et la cohésion du matelas. Par matelas de laine de verre classique, on entend un matelas obtenu selon une technique de fabrication de laine de verre généralement par centrifugation qui conduit à un matelas constitué de couches de fibres de verre celles-ci étant réparties en couches ou en strates quasi-bidimensionnelles. The inventors interpret the possibility of being able to reduce the quantity of material as being directly linked to the three-dimensional distribution of the fibers in the glass wool mat. Indeed, it seems that such a distribution allows the production of a mattress comprising less material and exhibiting mechanical properties similar to a conventional glass wool mattress. These mechanical properties are more particularly the resistance to compression and the cohesion of the mattress. By conventional glass wool mat is meant a mat obtained using a glass wool manufacturing technique generally by centrifugation which results in a mat consisting of layers of glass fibers, the latter being distributed in layers or in quasi-two-dimensional strata. .
Par contre, il est connu qu'une répartition tridimensionnelle des fibres dans un matelas de laine de verre diminue la résistance thermique du matelas. On the other hand, it is known that a three-dimensional distribution of the fibers in a glass wool mat reduces the thermal resistance of the mat.
Pour compenser cette diminution de la résistance thermique du matelas et conduire à des propriétés comparables à celles d'un élément composite réalisé à partir d'un matelas de laine de verre classique, il est proposé par l'invention de réaliser le matelas avec des fibres plus fines. L'invention propose ainsi dans une variante avantageuse un élément dont la majorité des fibres de verre, constituant le matelas, présente un diamètre inférieur à 5 jim et de préférence compris entre 3 et 4 ,um. Cette diminution du diamètre des fibres peut également contribuer à diminuer la quantité de matière dans le matelas.To compensate for this decrease in the thermal resistance of the mattress and lead to properties comparable to those of a composite element made from a conventional glass wool mattress, it is proposed by the invention to produce the mattress with fibers finer. The invention thus provides, in an advantageous variant, an element of which the majority of the glass fibers, constituting the mat, has a diameter of less than 5 μm and preferably between 3 and 4 μm. This reduction in the diameter of the fibers can also help to reduce the amount of material in the mattress.
De préférence encore, I'invention propose un élément dont le taux de liant compris dans le matelas de fibres de verre est inférieur à 10%. Un tel taux est inférieur à celui que l'on trouve dans un matelas classique et peut ainsi contribuer à diminuer la quantité de matière dans le matelas. II n'était pas évident de pouvoir diminuer ce taux, notamment dans le cas d'un matelas comportant des fibres fines, puisque habituellement la présence de fibres fines requiert au contraire une quantité plus importante de liant, tout au moins lorsqu'un matelas classique est réalisé. More preferably, the invention provides an element in which the rate of binder included in the glass fiber mat is less than 10%. Such a rate is lower than that found in a conventional mattress and can thus help to reduce the amount of material in the mattress. It was not easy to be able to reduce this rate, in particular in the case of a mattress comprising fine fibers, since usually the presence of fine fibers requires on the contrary a larger quantity of binder, at least when a conventional mattress is realised.
En ce qui concerne la répartition tridimensionnelle des fibres de verre dans le matelas, celle-ci est avantageusement obtenue selon l'invention par crêpage du matelas lors de la fabrication de celui-ci. Plus précisément, lors de la fabrication de fibres de verre par étirage centrifuge et/ou par étirage par soufflage, celles-ci sont récupérées par un convoyeur perforé qui est animé d'un mouvement de translation, notamment pour amener ces fibres constituant un matelas vers une étuve dans laquelle un liant préalablement déposé sur les fibres est polymérisé. Lors de leur réception sur le convoyeur les fibres se déposent et forment naturellement des couches dans lesquelles les fibres se répartissent selon des directions quasi-bidimensionnelles. As regards the three-dimensional distribution of the glass fibers in the mattress, this is advantageously obtained according to the invention by creping the mattress during the manufacture thereof. More precisely, during the manufacture of glass fibers by centrifugal drawing and / or by stretching by blowing, they are recovered by a perforated conveyor which is driven in a translational movement, in particular to bring these fibers constituting a mattress towards an oven in which a binder previously deposited on the fibers is polymerized. When they are received on the conveyor, the fibers are deposited and naturally form layers in which the fibers are distributed in quasi-two-dimensional directions.
Selon l'invention, le crêpage est réalisé par exemple lors du convoyage des fibres vers l'étuve. Une telle technique est notamment décrite dans le brevet EP-O 1 33 083. Cette technique consiste à créer une compression longitudinal du matelas notamment par passage d'un convoyeur à un autre, le second étant animé d'une vitesse inférieure. Selon une réalisation avantageuse de l'invention, le taux de crêpage, c'est-à-dire le rapport entre la vitesse du convoyeur de réception sur le dernier convoyeur, est compris entre 1,5 et 6 et de préférence entre 3 et 3,5. According to the invention, the creping is carried out for example during the conveying of the fibers to the oven. Such a technique is described in particular in patent EP-O 1 33 083. This technique consists in creating a longitudinal compression of the mattress in particular by passing from one conveyor to another, the second being driven at a lower speed. According to an advantageous embodiment of the invention, the creping rate, that is to say the ratio between the speed of the reception conveyor on the last conveyor, is between 1.5 and 6 and preferably between 3 and 3 , 5.
Selon différentes variantes de l'invention, le crêpage du matelas de fibres de verre peut être réalisé en une ou plusieurs étapes. According to different variants of the invention, the creping of the mat of glass fibers can be carried out in one or more stages.
Concernant la plaque rigide qui est par exemple collée au matelas de fibres de verre pour constituer un élément composite selon l'invention,
I'invention propose avantageusement d'utiliser une plaque de plâtre qui peut constituer une surface de parement pouvant supporter tout type de finition.Concerning the rigid plate which is for example glued to the mat of glass fibers to constitute a composite element according to the invention,
The invention advantageously proposes to use a plasterboard which can constitute a facing surface which can withstand any type of finish.
L'élément composite selon l'invention qui vient d'être décrit peut ainsi être utilisé pour réaliser une isolation thermo-acoustique, notamment en recouvrant des murs ou des cloisons. Un tel élément permet en outre de diminuer les coûts notamment par une économie de matière par rapport aux produits connus auparavant tout en conservant les propriétés de ceux-ci. The composite element according to the invention which has just been described can thus be used to produce thermo-acoustic insulation, in particular by covering walls or partitions. Such an element also makes it possible to reduce costs, in particular by saving material compared to previously known products while retaining their properties.
D'autres détails et caractéristiques avantageuses de l'invention ressortiront ci-après de la description d'un exemple de réalisation d'un élément composite selon l'invention, en référence aux figures 1 et 2, qui représentent
El figure 1 : une vue en coupe d'un élément composite selon l'art antérieur,
El figure 2 : une vue en coupe d'un élément composite selon l'invention.Other details and advantageous characteristics of the invention will emerge below from the description of an exemplary embodiment of a composite element according to the invention, with reference to FIGS. 1 and 2, which represent
El Figure 1: a sectional view of a composite element according to the prior art,
El Figure 2: a sectional view of a composite element according to the invention.
La figure 1 représente une vue en coupe d'un élément composite 1 constitué d'une part d'une plaque de plâtre 2 et d'un matelas de laine de verre 3. La plaque 2 et le matelas 3 sont liés l'un à l'autre par collage. Le matelas de laine de verre 3 a été réalisé à partir de fibres de verre obtenues par un procédé centrifuge interne dans lequel le verre passe au travers d'un centrifugeur percé de trous et est ensuite soumis à l'action d'étirage conjugué de la force centrifuge et d'un brûleur ou d'un souffleur comme décrit par exemple dans le brevet EP-091 866 et récupérées sur un convoyeur de réception qui les conduit jusqu'à une étuve dans laquelle un liant préalablement déposé sur les fibres est polymérisé. Selon ce type de procédé de fabrication, le matelas de fibres ne subit qu'une compression dans le sens de l'épaisseur. Le produit obtenu, comme le montre la figure 1, se compose essentiellement de fibres disposées quasi-parallèlement aux faces du matelas ou suivant une position très voisine. La répartition de fibres se fait donc essentiellement de façon bidimensionnelle. On peut en effet observer sur la figure 1 que le matelas de laine de verre est formé d'un ensemble de strates qui se superposent. Les propriétés tant mécanique, qu'acoustique et thermique d'un tel produit sont satisfaisantes et peuvent servir de référence pour l'analyse de l'élément composite selon l'invention. Figure 1 shows a sectional view of a composite element 1 consisting on the one hand of a plasterboard 2 and a glass wool mat 3. The plate 2 and the mat 3 are linked to each other. the other by gluing. The glass wool mat 3 was made from glass fibers obtained by an internal centrifugal process in which the glass passes through a centrifuge pierced with holes and is then subjected to the action of conjugate drawing of the glass. centrifugal force and a burner or a blower as described for example in patent EP-091 866 and recovered on a receiving conveyor which leads them to an oven in which a binder previously deposited on the fibers is polymerized. According to this type of manufacturing process, the fiber mat only undergoes compression in the direction of the thickness. The product obtained, as shown in FIG. 1, consists essentially of fibers arranged almost parallel to the faces of the mattress or in a very similar position. The distribution of fibers is therefore essentially two-dimensional. It can in fact be observed in FIG. 1 that the glass wool mattress is formed from a set of layers which are superimposed on each other. The mechanical, acoustic and thermal properties of such a product are satisfactory and can serve as a reference for the analysis of the composite element according to the invention.
Sur la figure 2 est représenté un élément composite 4 selon l'invention constitué d'une plaque de plâtre 5 collée à un matelas de laine de verre 6 dont les fibres ont été également réalisées par un procédé centrifuge interne. Le matelas 6 est constitué de fibres de verre réparties de facon tridimensionnelle. In FIG. 2 is shown a composite element 4 according to the invention consisting of a plasterboard 5 bonded to a glass wool mat 6, the fibers of which have also been produced by an internal centrifugal process. The mattress 6 is made of glass fibers distributed three-dimensionally.
Cette répartition tridimensionnelle des fibres a été obtenue par crêpage comme il I'a été décrit précédemment. II apparaît en effet sur cette figure 2, que l'on ne retrouve plus de fibres formant des strates qui se superposent mais un enchevêtrement de ces fibres. II s'avère que cette répartition particulière des fibres autorise, en utilisant essentiellement des fibres fines, c'est-à-dire avec un diamètre inférieur à 5 ijm, la fabrication d'un élément composite 4 possédant les mêmes propriétés qu'un élément composite 1, avec une quantité de matière inférieure pour réaliser le matelas 6.This three-dimensional distribution of the fibers was obtained by creping as described above. It appears in fact in this Figure 2, that we no longer find fibers forming layers which are superimposed but an entanglement of these fibers. It turns out that this particular distribution of the fibers allows, by using essentially fine fibers, that is to say with a diameter less than 5 μm, the manufacture of a composite element 4 having the same properties as an element. composite 1, with a smaller amount of material to make the mattress 6.
Des mesures ont été réalisées sur des éléments composites réalisés selon l'invention avec des épaisseurs de matelas de laine de verre comprises entre 30 et 100 mm. Ces produits sont réalisés pour présenter un coefficient de conductivité thermique à 100C de 33 mW/m C. Les masses volumiques des matelas de laine de verre sont inférieures à 60 kg/m3 et pour les épaisseurs du matelas supérieures à 50 mm, les masses volumiques sont inférieures à 55
3 kg/m . Le diamètre de la majorité des fibres constituant ces matelas est compris entre 3 et 4 pm. Les masses volumiques des matelas constituant des éléments composites tels que celui représenté sur la figure 1 sont de l'ordre de 65 kg/m3 et le coefficient de conductivité thermique à 100C de ces éléments est également de 33 mW/moC. Concernant la résistance acoustique, des essais ont montrés que l'élément composite selon l'invention présente des propriétés semblables à celles d'un élément tel que celui de la figure 1.Measurements were carried out on composite elements produced according to the invention with glass wool mat thicknesses of between 30 and 100 mm. These products are produced to have a coefficient of thermal conductivity at 100C of 33 mW / m C. The densities of the glass wool mattresses are less than 60 kg / m3 and for the thicknesses of the mattress greater than 50 mm, the densities are less than 55
3 kg / m. The diameter of the majority of the fibers constituting these mattresses is between 3 and 4 μm. The densities of the mattresses constituting composite elements such as that shown in FIG. 1 are of the order of 65 kg / m 3 and the coefficient of thermal conductivity at 100C of these elements is also 33 mW / mC. Regarding the acoustic resistance, tests have shown that the composite element according to the invention has properties similar to those of an element such as that of FIG. 1.
Ces résultats montrent bien qu'un élément composite selon l'invention peut être un isolant thermo-acoustique semblable à un élément composite traditionnel, celui-ci étant réalisé avec une quantité moindre de matière en ce qui concerne le matelas de laine de verre. These results clearly show that a composite element according to the invention can be a thermo-acoustic insulator similar to a traditional composite element, the latter being produced with a smaller quantity of material as regards the glass wool mattress.
En ce qui concerne les propriétés mécanique d'éléments composites selon l'invention, différentes mesures ont également été effectuées. Ces mesures ont été effectuées sur des éléments composites selon l'invention réalisés avec des matelas de laine de verre dont les épaisseurs sont comprises entre 30 et 100 mm. As regards the mechanical properties of composite elements according to the invention, various measurements were also carried out. These measurements were carried out on composite elements according to the invention made with glass wool mattresses whose thicknesses are between 30 and 100 mm.
Tout d'abord, des mesures de résistance à la compression ont été réalisées. En moyenne, les valeurs mesurées sont supérieures à 9 KPa. First, compressive strength measurements were taken. On average, the measured values are greater than 9 KPa.
Ensuite, des mesures de résistance à l'arrachement ont été effectuées. En moyenne, les valeurs sont supérieures à 6 KPa. Next, pullout resistance measurements were taken. On average, the values are greater than 6 KPa.
Ces différents résultats sont semblables à ceux obtenus sur des éléments composites de I' art antérieur tel que celui de la figure 1. II s'avère même que la résistance à l'arrachement qui correspond à la cohésion du matelas de laine de verre est sensiblement supérieur dans le cas des produits réalisés selon l'invention. Ces résultats confirment donc la possibilité de réaliser de tels éléments composites selon l'invention, notamment pour doubler des murs ou des cloisons, effectuer une isolation thermique et acoustique, et offrir simultanément une surface de parement apte à recevoir tout type de finition, par exemple en vue de la décoration d'une pièce dans une habitation ou un bureau. These different results are similar to those obtained on composite elements of the prior art such as that of FIG. 1. It even turns out that the resistance to tearing which corresponds to the cohesion of the glass wool mat is substantially. higher in the case of products produced according to the invention. These results therefore confirm the possibility of producing such composite elements according to the invention, in particular for lining walls or partitions, performing thermal and acoustic insulation, and simultaneously providing a facing surface suitable for receiving any type of finish, for example. for the decoration of a room in a home or an office.
