Abstract

The complex has reflective film surfaces (3) aluminized between which two needled fibrous layers (2) e.g. silica felts, are arranged. The layers are connected to each reflective film surface by parallel thread seams (5), where the needled fibrous material of three layers has a thickness between twelve to fifteen millimeters. The needled fibrous material of two aluminized layers has a surface density between point seven to point nine kilogram per meter square.

Description

La présente invention concerne un complexe multicouche isolant à hauteThe present invention relates to a multilayer insulating complex with high

température. Dans de nombreux domaines industriels dans lesquels il existe des sources de chaleur importante (fours industriels, tuyauteries hautes 5 températures,...), il faut isoler et confiner ces zones pour empêcher la diffusion de la chaleur à des organes qui ne peuvent supporter de haute température ou à des personnes. Les éléments d'isolation thermique actuels sont toutefois insatisfaisants sur de nombreux points techniques et économiques. 10 L'invention se propose de résoudre ces inconvénients. L'invention a pour objet un complexe multicouche d'isolation thermique et acoustique, comprenant au moins deux nappes de film réfléchissant aluminisé entre lesquelles sont disposées au moins deux couches de matériau fibreux aiguilleté, liées à chaque nappe par au moins 15 deux coutures parallèles de fils. L'invention fournit ainsi un complexe dont l'effet de protection thermique et notamment de protection contre le feu combine une composante de réflexion qui est conférée par les nappes de film aluminisé et une composante d'isolation qui est conférée par la faible conductivité 20 thermique des couches internes. Selon une forme d'exécution de l'invention, la couche de matériau fibreux aiguilleté est un feutre de verre. Selon une autre forme de réalisation de l'invention, la couche de matériau fibreux aiguilleté est un feutre de silice. 25 De préférence, les trois couches de matériau fibreux sont d'épaisseur comprise entre 12 mm et 1 5 mm. Cette disposition permet de créer un complexe qui présente une importante souplesse et donc lui permet d'épouser des surfaces gauches. Selon une forme de réalisation, le complexe présente deux 30 couches de matériau fibreux aiguilleté ayant une ruasse surfacique comprise entre 0,70 et 0,90 kg/m2. Dans une autre forme de réalisation, le complexe présente trois couches de matériau fibreux aiguilleté ayant une ruasse surfacique comprise entre 1,10 et 1,20 kg/m2.  temperature. In many industrial fields in which there are significant heat sources (industrial furnaces, high temperature pipes, ...), it is necessary to isolate and confine these zones to prevent the diffusion of heat to organs that can not withstand heat. high temperature or to people. The current thermal insulation elements are however unsatisfactory on many technical and economic points. The invention proposes to solve these disadvantages. The invention relates to a multilayer complex of thermal and acoustic insulation, comprising at least two sheets of aluminized reflective film between which are arranged at least two layers of fibrous material needled, bonded to each sheet by at least two parallel seams of son. The invention thus provides a complex whose thermal protection and especially fire protection effect combines a reflection component which is conferred by the aluminized film layers and an insulation component which is conferred by the low thermal conductivity. internal layers. According to one embodiment of the invention, the layer of needled fibrous material is a glass felt. According to another embodiment of the invention, the layer of needled fibrous material is a silica felt. Preferably, the three layers of fibrous material are between 12 mm and 15 mm thick. This arrangement makes it possible to create a complex that has considerable flexibility and thus allows it to marry left surfaces. According to one embodiment, the complex has two layers of fibrous needled material having a surface area of between 0.70 and 0.90 kg / m 2. In another embodiment, the complex has three layers of needled fibrous material having a surface area of between 1.10 and 1.20 kg / m 2.

Pour sa bonne compréhension, l'invention est décrite en référence au dessin ci annexé représentant à titre d'exemple non limitatif une forme de réalisation d'un complexe selon celle-ci. Figure 1 représente le complexe anti feu en coupe longitudinale, 5 Figure 2 montre le complexe en vue par-dessus. En se référant tout d'abord à la figure 1, on peut voir que le complexe est constitué de trois couches 2 internes d'épaisseur égale ; les couches 2 sont constituées à base de feutre de verre comprenant des fibres de verre continues dont le liage se fait par un aiguilletage mécanique 10 contrôlé. La masse surfacique de ces couches 2 est de l'ordre de 1,10 kg/m2 à 1,20 kg/m2. Il peut également être envisagé de réaliser les trois couches 2 centrales dans un feutre aiguilleté de silice. De part et d'autre de ces trois couches 2 centrales, il est prévu 15 deux nappes 3 d'un film aluminisé. La liaison entre chacune des fibres est réalisée par deux coutures longitudinales d'un fil 5, par exemple de nylon thermorésistant. Le complexe se présente sous la forme d'une laize d'une largeur de l'ordre de un mètre et d'une longueur de dix à cinquante mètres selon 20 l'épaisseur de ces couches internes. On note que ce complexe présente une souplesse importante du fait de la constitution de son âme par trois couches séparées qui sont susceptibles de glisser les unes par rapport aux autres et qui permet au complexe d'épouser des formes gauches.  For a good understanding, the invention is described with reference to the accompanying drawing showing by way of non-limiting example an embodiment of a complex according thereto. Figure 1 shows the anti-fire complex in longitudinal section, Figure 2 shows the complex seen from above. Referring first to Figure 1, it can be seen that the complex consists of three inner layers 2 of equal thickness; the layers 2 are made of glass felt comprising continuous glass fibers whose binding is done by a controlled mechanical needling. The weight per unit area of these layers 2 is of the order of 1.10 kg / m 2 to 1.20 kg / m 2. It may also be envisaged to make the three central layers 2 in a needle felt needle. On either side of these three central layers 2, two sheets 3 of an aluminized film are provided. The connection between each of the fibers is made by two longitudinal seams of a thread 5, for example of heat-resistant nylon. The complex is in the form of a width of about one meter in width and ten to fifty meters in length depending on the thickness of these inner layers. Note that this complex has a significant flexibility due to the constitution of its soul by three separate layers that are likely to slide relative to each other and allows the complex to marry the left forms.

25 Le complexe agit sur deux modes : d'une part, il réfléchit la chaleur par ses couches aluminisées, et d'autre part, il isole grâce à la faible conductibilité thermique de ces trois couches 2 internes et peut ainsi résister à des température de l'ordre de 150 C de manière continue. Bien entendu, l'invention n'est pas limitée à la forme de 30 réalisation décrite ci-dessus à titre d'exemple non limitatif mais elle en embrasse au contraire toutes les formes de réalisation. Ainsi il peut être envisagé de prévoir deux couches 2 centrales de matériau fibreux aiguilleté qui dans ce cas peuvent présenter une masse surfacique de l'ordre de 0,70 kg/m2 à 0,90 kg/m2.The complex acts in two modes: on the one hand, it reflects the heat by its aluminized layers, and on the other hand, it isolates thanks to the low thermal conductivity of these three internal layers 2 and can thus withstand in the order of 150 C continuously. Of course, the invention is not limited to the embodiment described above by way of non-limiting example but it encompasses all the embodiments. Thus it may be envisaged to provide two central layers 2 of needled fibrous material which in this case may have a mass per unit area of about 0.70 kg / m2 to 0.90 kg / m2.
