Description
La présente invention se rapporte à un panneau isolant en laine minérale, particulièrement en laine de roche, lié par une résine thermodurcissable. The present invention relates to an insulating panel made of mineral wool, particularly rock wool, bonded by a thermosetting resin.
Un panneau de ce type, constitué en laine minérale, particulièrement en laine de roche, traité par une résine thermodurcissable, cette résine thermodurcissable étant traitée par passage du panneau dans une zone de chauffage, est bien connu et utilisé. A panel of this type, made of mineral wool, particularly rock wool, treated with a thermosetting resin, this thermosetting resin being treated by passing the panel through a heating zone, is well known and used.
Un panneau isolant de ce type présente l'inconvénient que, lorsque celui-ci est appliqué à une surface devant être isolée, qui a été préalablement munie d'un revêtement de bitume, de larges quantités de bitume sont absorbées. Cela présente l'inconvénient que, d'une part, le prix de l'isolation augmente tandis que, d'autre part, des quantités considérables de matériel sont consommées, ce qui réduit les propriétés d'isolation du panneau isolant, puisque le bitume est absorbé dans les cavités du panneau isolant qui servent à l'isolation. An insulating panel of this type has the disadvantage that, when it is applied to a surface to be insulated, which has been previously provided with a coating of bitumen, large amounts of bitumen are absorbed. This has the disadvantage that, on the one hand, the price of insulation increases while, on the other hand, considerable quantities of material are consumed, which reduces the insulation properties of the insulating panel, since bitumen is absorbed in the cavities of the insulating panel which are used for insulation.
On a déjà proposé pour remédier à cela des surfaces particulières sur de tels panneaux isolants, mais ce procédé n'a pas trouvé d'application pratique puisque les revêtements supérieurs de verre soluble additionné de substances minérales devaient être utilisés. En plus, ce procédé entraîne avec lui une diminution des propriétés d'isolation et, d'autre part, n'empêche pas une consommation exagérée de bitume. Particular surfaces have already been proposed to remedy this on such insulating panels, but this process has not found practical application since the upper coatings of soluble glass supplemented with mineral substances had to be used. In addition, this process brings with it a reduction in the insulation properties and, on the other hand, does not prevent an excessive consumption of bitumen.
Le but principal de la présente invention est de réaliser un panneau du type précité qui ne présente pas ces inconvénients et qui permette, tout en maintenant totalement ces qualités isolantes, une consommation considérablement plus faible de bitume. The main object of the present invention is to produce a panel of the aforementioned type which does not have these drawbacks and which allows, while fully maintaining these insulating qualities, a considerably lower consumption of bitumen.
Cela est réalisé, selon la présente invention, en ce que le panneau porte, comme couche supérieure, une couche de tissu ou une couche non tissée ne se ramollissant (ou ne se plastifiant) pas à des températures inférieures à 100CC. This is achieved, according to the present invention, in that the panel carries, as an upper layer, a layer of fabric or a non-woven layer which does not soften (or not plasticize) at temperatures below 100 ° C.
Une telle couche de tissu ou une telle couche non tissée est réalisée en fibre minérale renforcée ou non, et de préférence est obtenue très rapidement par des fibres de verre non tissées liées entre elles par une résine thermodurcissable. Such a fabric layer or such a nonwoven layer is made of mineral fiber, reinforced or not, and is preferably obtained very quickly by nonwoven glass fibers bonded together by a thermosetting resin.
Les avantages d'une telle couche non tissée sont évidents du fait que, lorsqu'une couverture en fibres de verre non tissées est utilisée comme couche supérieure, la consommation de bitume est de l'ordre de 1 à 1 '/ikg/m2, tandis que, lorsque ce revêtement en fibres de verre non tissées n'est pas utilisé, la quantité de bitume consommée est de l'ordre de 2,5 à 3 kg/m2. The advantages of such a non-woven layer are obvious from the fact that, when a non-woven glass fiber cover is used as the upper layer, the consumption of bitumen is of the order of 1 to 1 ′ / ikg / m2, while, when this coating of non-woven glass fibers is not used, the amount of bitumen consumed is of the order of 2.5 to 3 kg / m2.
Les fibres de verre non tissées peuvent être constituées par des fibres de verre renforcées de manière à obtenir un renforcement pour augmenter la résistance à l'impact de la structure isolante. En conséquence, il est ainsi possible de marcher sur un tel revêtement, ce qui représente un avantage considérable en pratique. The nonwoven glass fibers can be constituted by glass fibers reinforced so as to obtain a reinforcement to increase the impact resistance of the insulating structure. As a result, it is thus possible to walk on such a coating, which represents a considerable advantage in practice.
De façon surprenante, on a trouvé que non seulement la consommation de bitume est limitée par l'utilisation d'une couche non tissée, mais que le bitume pénètre dans le panneau de fibres minérales, de telle sorte qu'une adhérence adéquate est obtenue entre la couche non tissée et le panneau en laine minérale. On aurait pu s'attendre que, du fait de la texture ouverte de la couche non tissée, la dépense en bitume serait très petite; ce n'est toutefois pas le cas. Surprisingly, it has been found that not only is the consumption of bitumen limited by the use of a non-woven layer, but that the bitumen penetrates into the mineral fiber panel, so that adequate adhesion is obtained between the non-woven layer and the mineral wool panel. One would have expected that, due to the open texture of the nonwoven layer, the bitumen expenditure would be very small; however, this is not the case.
On utilise de préférence des fibres minérales non tissées ayant un poids de surface compris entre 20 et 60 g/m2 de préférence entre 40 et 50 g/m2, liées avec 15 à 30% en poids, de préférence 20% en poids, d'une résine thermodurcissable, de préférence une résine formaldéhyde. Preference is given to using non-woven mineral fibers having a surface weight of between 20 and 60 g / m2, preferably between 40 and 50 g / m2, bonded with 15 to 30% by weight, preferably 20% by weight, of a thermosetting resin, preferably a formaldehyde resin.
Cette invention se rapporte également au procédé de fabrication d'un panneau isolant en laine minérale en passant ce panneau de laine minérale muni d'une résine thermodurcissable à travers une zone de chauffage, de sorte que, selon l'invention, avant ou pendant le passage à travers la zone de chauffage, un tissu ou une couche non tissée ne se ramollissant pas en dessous de 100°C soit appliqué à la surface de la feuille. This invention also relates to the method of manufacturing an insulating mineral wool panel by passing this mineral wool panel provided with a thermosetting resin through a heating zone, so that, according to the invention, before or during the passage through the heating zone, a non-woven fabric or layer which does not soften below 100 ° C. is applied to the surface of the sheet.
Il en résulte que le tissu ou la couche non tissée s'unit par l'agent liant thermodurcissable avec la surface du panneau isolant. En outre, une surface très plate du panneau est obtenue, ce qui permet de réduire la consommation de bitume, puisque la rugosité du panneau augmente automatiquement la consommation de bitume. As a result, the fabric or nonwoven layer is united by the thermosetting binding agent with the surface of the insulating panel. In addition, a very flat surface of the panel is obtained, which makes it possible to reduce the consumption of bitumen, since the roughness of the panel automatically increases the consumption of bitumen.
On obtient une réduction considérable du bitume utilisé, bien que la couche non tissée ou la couche de tissu soit collée par le bitume sur la feuille de laine minérale, ce qui permet de consommer moins de bitume. A considerable reduction in the bitumen used is obtained, although the non-woven layer or the layer of fabric is bonded by the bitumen to the sheet of mineral wool, which makes it possible to consume less bitumen.
Le dessin annexé illustre schématiquement et à titre d'exemple une forme d'exécution du panneau selon l'invention. The accompanying drawing illustrates schematically and by way of example an embodiment of the panel according to the invention.
La fig. 1 est une coupe au travers d'un panneau isolant de laine minérale. Fig. 1 is a section through an insulating panel of mineral wool.
La fig. 2 représente une autre forme d'exécution d'une telle feuille appliquée à une surface devant être isolée. Fig. 2 shows another embodiment of such a sheet applied to a surface to be insulated.
La fig. 3 illustre à plus grande échelle un détail de la surface du panneau isolant. Fig. 3 illustrates on a larger scale a detail of the surface of the insulating panel.
Dans ces dessins, un panneau isolant 1 est illustré formé de laine de roche 2 présentant des espaces isolants 3. In these drawings, an insulating panel 1 is illustrated formed from rock wool 2 having insulating spaces 3.
La laine de roche est interconnectée à l'aide d'une résine polyester thermodurcissable, cette résine thermodurcissable étant traitée dans une zone de chauffage à une température comprise entre 140 et 170°C. The rock wool is interconnected using a thermosetting polyester resin, this thermosetting resin being treated in a heating zone at a temperature between 140 and 170 ° C.
La surface 4 du panneau isolant en laine minérale est très irrégulière, ce qui a pour effet que, lorsque ce panneau est appliqué à une surface à isoler 5, une grande quantité de bitume est utilisée pour la couche 6. Le bitume est en effet absorbé par le panneau en laine minérale. The surface 4 of the mineral wool insulating panel is very irregular, which has the effect that, when this panel is applied to a surface to be insulated 5, a large amount of bitumen is used for layer 6. The bitumen is indeed absorbed by the mineral wool panel.
L'invention a pour objet d'obvier à ces difficultés en appliquant une couche de tissu ou une couche non tissée 7 à la surface du panneau en laine minérale. Cette couche 7 consiste de préférence en fibres de vërre non tissées, les fibres de verre non tissées présentant The object of the invention is to overcome these difficulties by applying a layer of fabric or a non-woven layer 7 to the surface of the mineral wool panel. This layer 7 preferably consists of non-woven glass fibers, the non-woven glass fibers having

un poids de 45 g/m2, liées avec 20% en poids d'une résine formaldéhyde. a weight of 45 g / m2, bound with 20% by weight of a formaldehyde resin.
Du fait de l'application de cette couche non tissée 7 avant le durcissement du panneau en laine minérale, on obtient que cette couche non tissée adhère efficacement au panneau pendant le 5 Due to the application of this nonwoven layer 7 before the hardening of the mineral wool panel, it is obtained that this nonwoven layer adheres effectively to the panel during the 5
traitement de la résine thermodurcissable. treatment of thermosetting resin.
L'application de fibres de verre non tissées présente l'avantage qu'une surface très plate du panneau est obtenue, ce qui réduit la consommation de bitume de façon considérable, bien qu'il ait été trouvé de façon surprenante que, du fait de l'application de la io couche non tissée, on obtient tout de même une bonne adhérence entre le panneau et la surface devant être isolée, tout en diminuant considérablement la consommation de bitume. The application of non-woven glass fibers has the advantage that a very flat surface of the panel is obtained, which reduces bitumen consumption considerably, although it has surprisingly been found that, due to the application of the nonwoven layer, a good adhesion is nevertheless obtained between the panel and the surface to be insulated, while considerably reducing the consumption of bitumen.
Cela apparaît du fait que, lorsque l'on utilise une couche en fibres de verre non tissées, la consommation de bitume est réduite à 1 à 1,5 kg/m2 à la place de la quantité normale de 2,5 à 3 kg/m2. This appears from the fact that, when using a layer of non-woven glass fibers, the consumption of bitumen is reduced to 1 to 1.5 kg / m2 instead of the normal amount of 2.5 to 3 kg / m2.
Si désiré, on peut renforcer la couche non tissée de fibres de verre 7, de manière à augmenter la résistance de la feuille isolante à des charges locales de façon considérable. Cela donne la possibilité à la structure ainsi obtenue de résister à de plus fortes charges et, notamment, il est possible de marcher sur cette structure. If desired, the nonwoven layer of glass fibers 7 can be reinforced, so as to considerably increase the resistance of the insulating sheet to local loads. This gives the structure thus obtained the possibility of withstanding higher loads and, in particular, it is possible to walk on this structure.
Il est évident que le panneau peut d'abord être traité, puis poli, et ensuite seulement recevoir la couche non tissée. It is obvious that the panel can first be treated, then polished, and then only receive the nonwoven layer.
Bien que cette invention ait été décrite en référence à un panneau en laine de roche, il est évident que cette invention est aussi utilisable et applicable à un panneau par exemple de fibres de verre. Although this invention has been described with reference to a rock wool panel, it is obvious that this invention is also usable and applicable to a panel for example of glass fibers.
