Abstract
Description
"Article moulé pour la protection
anti-feu"
La présente invention concerne un article moulé et/ou projeté en forme de plaque, porte, panneau, cloison, éléments de construction de formes planes ou courbes, comprenant un corps moulé et/ou projeté ayant un pouvoir de protection contre le feu, à base de ciment réfractaire et/ou du type Portland et/ou de type magnésien et/ou de chaux et/ou de plâtre, de particules inorganiques et/ou d'un composé inorganique comportant des molécules d'eau de cristallisation."Molded item for protection
anti fire"
The present invention relates to an article molded and / or projected in the form of a plate, door, panel, partition, building elements of flat or curved shapes, comprising a molded and / or projected body having a fire protection power, based of refractory cement and / or of the Portland type and / or of the magnesian type and / or of lime and / or of plaster, of inorganic particles and / or of an inorganic compound comprising molecules of water of crystallization.
Des compositions de tels articles sont connues notamment par le brevet français au nom de la demanderesse n" 2 458 519 et son addition 2 478 072. Compositions of such articles are known in particular from the French patent in the name of the applicant No. 2,458,519 and its addition 2,478,072.
Les revêtements projetés et/ou les articles moulés ayant cette composition assurent une excellente protection contre le feu, notamment grâce à la présence d'un composé comportant des molécules d'eau de cristallisation. The sprayed coatings and / or molded articles having this composition provide excellent protection against fire, in particular thanks to the presence of a compound comprising molecules of water of crystallization.
En effet, la libération de ces molécules d'eau de cristallisation, maintient la température de l'article à une valeur relativement basse pendant une certaine durée, malgré la forte chaleur de la flamme à laquelle l'article est exposé. Les effets néfastes de la flamme sont retardés, ce qui présente un avantage considérable. In fact, the release of these molecules of water of crystallization maintains the temperature of the article at a relatively low value for a certain period of time, despite the high heat of the flame to which the article is exposed. The harmful effects of the flame are delayed, which has a considerable advantage.
Ces articles connus présentent toutefois quelques inconvénients. These known articles however have some drawbacks.
Ils sont relativement lourds du fait qu'ils sont en grande partie à base de ciment. They are relatively heavy because they are largely based on cement.
Leur résistance mécanique est médiocre et de ce fait ils ne peuvent pas être utilisés pour garnir par exemple une porte, car ils ne résisteraient pas aux nombreux chocs créés lors des fermetures brutales de ces portes. Their mechanical resistance is poor and therefore they cannot be used to garnish for example a door, because they would not withstand the numerous shocks created during the brutal closings of these doors.
De plus, le pouvoir isolant thermique de ces articles est faible. In addition, the thermal insulating power of these articles is low.
En outre, ces articles ne sont pas étanches. In addition, these items are not waterproof.
Le but de la présente invention est de réaliser des articles moulés et/ou projetés du type mentionné au début de la présente description qui soient à la fois plus léger, plus isolant, plus résistant et étanche. The object of the present invention is to produce molded and / or sprayed articles of the type mentioned at the beginning of this description which are both lighter, more insulating, more resistant and waterproof.
L'invention vise ainsi un article projeté et/ou moulé en forme de plaque, porte, panneau, cloison, éléments de construction de formes planes ou courbes, comprenant un corps moulé et/ou projeté ayant un pouvoir de protection contre le feu, à base de ciment réfractaire et/ou du type ciment Portland et/ou du type magnésien et/ou de chaux et/ou plâtres et/ou de sels minéraux et/ou d'un phosphate d'alumine et/ou d'un silicate et/ou d'un liant organique, de particules inorganiques et/ou d'un composé inorganique comportant des molécules d'eau de cristallisation et/ou d'un sel minéral. The invention thus relates to an article projected and / or molded in the form of a plate, door, panel, partition, construction elements of planar or curved shapes, comprising a molded and / or projected body having a fire protection power, with base of refractory cement and / or of the Portland cement type and / or of the magnesian type and / or of lime and / or plasters and / or of mineral salts and / or of an alumina phosphate and / or of a silicate and / or an organic binder, inorganic particles and / or an inorganic compound comprising molecules of water of crystallization and / or a mineral salt.
Suivant l'invention, cet article moulé et/ou projeté est caractérisé en ce que ledit corps renferme des blocs d'une matière thermiquement isolante, ledit corps étant entouré d'au moins une couche de résine et/ou d'un sel minéral et/ou d'un phosphate d'alumine. According to the invention, this molded and / or sprayed article is characterized in that said body contains blocks of a thermally insulating material, said body being surrounded by at least one layer of resin and / or of an inorganic salt and / or an alumina phosphate.
Les blocs en matière isolante noyés dans le corps, allègent le bloc tout en lui conférant des propriétés d'isolation thermique. The blocks of insulating material embedded in the body, lighten the block while giving it thermal insulation properties.
La couche de résine et/ou de sel minéral et/ou de liant chimique qui entoure le corps à base de ciment, renforce mécaniquement ce dernier, rend sa surface étanche et améliore sa finition extérieure. The layer of resin and / or mineral salt and / or chemical binder which surrounds the cement-based body, mechanically strengthens the latter, makes its surface waterproof and improves its exterior finish.
Selon une version avantageuse de l'invention, lesdits blocs sont en une matière thermiquement isolante, de préférence rigide, poreuse et résistant à haute température. According to an advantageous version of the invention, said blocks are made of a thermally insulating material, preferably rigid, porous and resistant to high temperature.
Ces blocs améliorent la résistance mécanique du corps, sans affecter les propriétés de protection contre le feu, ce d'autant plus que ces blocs sont choisis de préférence parmi ceux pouvant résister à haute température. These blocks improve the mechanical resistance of the body, without affecting the fire protection properties, all the more since these blocks are preferably chosen from those capable of withstanding high temperature.
Ces blocs sont de préférence composés de billes de verre et/ou en mousse de verre, et/ou en fibres de verre et/ou en fibres minérales et/ou en fibres organiques, ils peuvent même être en polystyrène de préférence non combustible et/ou de la mousse phénolique. These blocks are preferably composed of glass beads and / or glass foam, and / or glass fibers and / or mineral fibers and / or organic fibers, they can even be made of preferably non-combustible polystyrene and / or phenolic foam.
De préférence, le volume total desdits blocs représente entre 5 et 95 % du volume total du corps moulé. Preferably, the total volume of said blocks represents between 5 and 95% of the total volume of the molded body.
De préférence également la couche de résine est une résine époxy et/ou un sel minéral, et/ou un silicate. Preferably also the resin layer is an epoxy resin and / or an inorganic salt, and / or a silicate.
Cette résine est de préférence chargée de fibres minérales, par exemple des fibres de carbone pour améliorer la résistance mécanique de la couche. This resin is preferably loaded with mineral fibers, for example carbon fibers to improve the mechanical strength of the layer.
Selon une version préférée de l'invention, au moins la partie de la couche de résine située à l'extérieur de l'article et destinée à être exposée au feu, renferme des fibres fusibles. According to a preferred version of the invention, at least the part of the resin layer located outside the article and intended to be exposed to fire, contains fusible fibers.
Lorsque l'article est exposé à une flamme, les fibres fusibles fondent en créant à l'intérieur de la résine des pores ou des canaux qui rendent la couche de résine perméable à la vapeur résultant de la libération des molécules d'eau du composé comportant des molécules d'eau de cristallisation. La couche de résine et/ou de sel minéral peut également comporter une soupape de sécurité telle que par exemple une feuille d'aluminium. When the article is exposed to a flame, the fusible fibers melt, creating pores or channels inside the resin which make the resin layer permeable to vapor resulting from the release of the water molecules from the compound comprising molecules of water of crystallization. The resin and / or mineral salt layer may also include a safety valve such as, for example, aluminum foil.
D'autres particularités et avantages de l'invention apparaîtront encore dans la description ciaprès. Other features and advantages of the invention will become apparent in the description below.
La figure unique en arraché annexée est une vue en coupe représentant deux possibilités de panneaux conformes à l'invention. The single appended broken away figure is a sectional view showing two possibilities of panels according to the invention.
La figure annexée représente un article moulé et/ou projeté en forme de plaque pouvant constituer une porte, un panneau, une cloison ou tout autre élément de construction de forme plane ou courbe. Cet article comprend un corps moulé 1 ayant un pouvoir de protection contre le feu, à base d'un liant hydraulique et/ou organique, de particules inorganiques et/ou d'un composé inorganique comportant des molécules d'eau de cristallisation. The appended figure represents an article molded and / or projected in the form of plate which can constitute a door, a panel, a partition or any other building element of planar or curved shape. This article comprises a molded body 1 having a fire protection power, based on a hydraulic and / or organic binder, inorganic particles and / or an inorganic compound comprising molecules of water of crystallization.
La composition du corps 1 peut par exemple être l'une de celles décrites dans le brevet français n" 2 458 519 et dans son addition nO 2 478 072. The composition of the body 1 may for example be one of those described in French patent No. 2,458,519 and in its addition No. 2,478,072.
Suivant l'invention, le corps 1 renferme des blocs tels que représentés en 2a, 2b, 2c ou en un seul bloc 2 d'une matière thermiquement isolante. According to the invention, the body 1 contains blocks as shown in 2a, 2b, 2c or in a single block 2 of a thermally insulating material.
Par ailleurs, le corps 1 est entouré d'un étui rigide qui est constitué d'une couche de résine 3 et/ou d'un sel minéral, et/ou d'un silicate. Furthermore, the body 1 is surrounded by a rigid case which consists of a layer of resin 3 and / or a mineral salt, and / or a silicate.
Les blocs 2a, 2b, 2c ou le bloc 2 sont de préférence, en une matière thermiquement isolante rigide, poreuse et résistant à haute température, comme par exemple de la mousse de verre. Cependant le ou les blocs peuvent être également des matelas de fibres organiques et/ou minérales imprégnés de préférence d'un produit saturé d'eau de cristallisation par exemple, d'acide borique et/ou de phosphate trisodique et/ou d'alumine hydratée et/ou d'un liant alumineux (FFB10). The blocks 2a, 2b, 2c or the block 2 are preferably made of a rigid thermally insulating material, porous and resistant to high temperature, such as for example glass foam. However, the block or blocks may also be mattresses of organic and / or mineral fibers preferably impregnated with a product saturated with water of crystallization, for example, boric acid and / or trisodium phosphate and / or hydrated alumina and / or an aluminous binder (FFB10).
De préférence, le volume total des blocs 2 représente entre 5 et 95 % du volume total du corps moulé 1. Preferably, the total volume of the blocks 2 represents between 5 and 95% of the total volume of the molded body 1.
Par exemple l'étui rigide composé de la couche de résine 3 peut être en résine époxy. Cette résine 3 est de préférence chargée de fibres minérales, telles que la fibre de carbone, de verre, de roche etc. For example, the rigid case composed of the resin layer 3 can be made of epoxy resin. This resin 3 is preferably loaded with mineral fibers, such as carbon fiber, glass, rock etc.
De préférence également, au moins la partie de la couche de résine 3 située à l'extérieur de l'article et destinée à être exposée au feu, renferme des fibres fusibles, telles que des fibres de matière thermoplastique, comme le polypropylène. Preferably also, at least the part of the resin layer 3 located outside the article and intended to be exposed to fire, contains fusible fibers, such as fibers of thermoplastic material, such as polypropylene.
Les principaux avantages du panneau de protection anti-feu que l'on vient de décrire sont les suivants
Les propriétés anti-feu du panneau sont dues à la composition en elle-même connue du corps moulé 1.The main advantages of the fire protection panel just described are as follows:
The fire-fighting properties of the panel are due to the composition in itself known of the molded body 1.
La présence du ou des blocs isolants 2 au sein du corps 1 allège le panneau et confère à celui-ci un excellent pouvoir d'isolation thermique et augmente même sa tenue au feu lorsqu'il est ou qu'ils sont saturés de produits comportant de l'eau de cristallisation. The presence of the insulating block (s) 2 within the body 1 lightens the panel and gives it excellent thermal insulation power and even increases its resistance to fire when it is or is saturated with products comprising water of crystallization.
La résine 3 qui entoure l'ensemble du corps moulé 1 améliore la résistance mécanique de ce dernier, rend celui-ci étanche et donne au panneau un état de surface améliore. The resin 3 which surrounds the whole of the molded body 1 improves the mechanical resistance of the latter, makes it waterproof and gives the panel an improved surface condition.
Lorsqu'un tel panneau est exposé au feu, la montée en température du panneau est retardée notamment du fait de la libération des molécules d'eau de cristallisation du liant hydraulique et/ou chimique ainsi que celle qui peut être contenue dans le ou les blocs 2, ce qui se fait à une température relativement basse. Toutefois, la couche de résine 3 empêche les molécules d'eau de s'échapper à l'extérieur. When such a panel is exposed to fire, the temperature rise of the panel is delayed in particular due to the release of the molecules of water of crystallization from the hydraulic and / or chemical binder as well as that which may be contained in the block or blocks 2, which is done at a relatively low temperature. However, the resin layer 3 prevents the water molecules from escaping outside.
Cependant, des fibres fusibles contenues dans la résine, en fondant créent des canaux ou pores qui rendent la résine perméable à la vapeur d'eau et freinent sa sortie. However, fusible fibers contained in the resin, by melting create channels or pores which make the resin permeable to water vapor and slow down its exit.
Les panneaux selon l'invention peuvent bien entendu être moulés sous forme de manchons ou demicoquilles pour protéger par exemple des conduites. The panels according to the invention can of course be molded in the form of sleeves or half-shells to protect, for example, pipes.
