Definitions
- the present invention relates to a molded fire article in the form of a plate, door, panel, partition, construction element of flat or curved shapes, comprising a molded body having a protective power against the fire and containing one or more blocks of a thermally insulating material, said body being produced from a composition comprising inorganic particles and a binder.
- a molded article of the aforementioned type comprising a resistant body enclosing a core of expanded foam.
- the body is made from cement-based mud to form a cement-based matrix reinforced in three dimensions by non-woven fibers.
- the outer layer has the appearance, mechanical strength, hardness and durability of ordinary concrete.
- the foam core lightens the article and gives it thermal insulation properties.
- this item has a low fire resistance.
- This structure has the drawback of requiring a long, delicate and costly assembly of the sheets or plates together.
- this structure is not usable in the case of a molded article.
- the object of the present invention is to remedy the drawbacks of known articles and to provide a molded article of the aforementioned type which is light and very inexpensive, which has excellent fire resistance, and which also has mechanical resistance and surface hardness. predetermined.
- the article of the aforementioned type is characterized in that the body comprises at least one inorganic compound providing molecules of water of crystallization, is adapted to give said article a predetermined mechanical resistance and fire resistance, and is covered with at least one hard and resistance layer of resin and / or a chemical binder, deposited on the entire outer surface of said body after the setting of said binder.
- the hard and resistant outer layer of resin or chemical binder gives the molded article the surface hardness and durability necessary in normal use for such an article. This layer disappears if the temperature rises above a predetermined threshold and does not intervene in terms of fire resistance. On the other hand, this layer mechanically strengthens the body, makes its outer surface waterproof or substantially sealed, and improves the appearance and the state of this surface.
- the molded body then has the functions of substantially ensuring by itself the mechanical resistance of the molded article in normal use thereof, that is to say for handling, transport, assembly, installation and the use of said article, as well as, in combination with the insulating blocks which it contains, the fire resistance required for said article.
- Such an article provides excellent protection against fire, in particular by virtue of the presence of a compound comprising molecules of water of crystallization.
- said blocks are made of a thermally insulating material, preferably rigid, porous and resistant to high temperature.
- 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.
- 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.
- the total volume of said blocks represents between 5 and 95% of the total volume of the molded body.
- the hard and resistant layer is preferably made of epoxy resin.
- This resin is preferably loaded with mineral fibers, for example carbon fibers, to improve the mechanical strength of the layer.
- At least the part of the resin layer located outside the article and intended to be exposed to fire contains fusible fibers.
- the resin and / or chemical binder layer may also include a safety valve such as, for example, aluminum foil.
- the single appended broken away figure is a sectional view showing two possibilities of panels according to the invention.
- 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, chemical and / or organic binder, inorganic particles and an inorganic compound comprising molecules of water of crystallization.
- 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.
- the molecules of water of crystallization can be provided by a chemical or hydraulic binder. They can also be provided by a hydrated mineral salt, in a manner known in itself which it is not necessary to recall in detail here.
- the hydraulic binder can be in known manner, for example, a refractory cement, a Portland type cement, a magnesian cement, lime, a plaster, used alone or in combination with each other and with known additives. .
- the body 1 contains blocks as shown in 2a, 2b, 2c or a single block 2 of a thermally insulating material.
- the body 1 is surrounded by a rigid and resistant case which consists of a layer 3 composed of resin and / or a chemical binder, silicate or phosphate of an alkali or alkaline-earth metal, especially sodium. .
- 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.
- 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).
- the total volume of the blocks 2 represents between 5 and 95% of the total volume of the molded body 1.
- the rigid and resistant 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.
- at least the part of the resin layer 3 situated outside the article and intended to be exposed to fire contains fusible fibers, such as fibers of thermoplastic material, such as polypropylene or PVC. (chlorofibers).
- the composition from which the body 1 is made comprises a compound providing molecules of water of crystallization, inorganic particles, in particular lightening materials such as perlite or expanded vermiculite, a preferably hydraulic binder, if necessary, a surfactant to lather the mixture and emulsify, aerate and lighten the body 1.
- the nature and the particle size of the various components can be chosen so that the composition sintered at least partially at a temperature at which certain components and the binder decompose or lose part of their properties.
- Such a body which can have a specific weight of the order of 250 to 350 kg / m, then has sufficient mechanical strength to be self-supporting and to withstand the constraints associated with handling operations, storage, assembly, installation.
- this body has a low surface hardness and resistance, and it is the resin which gives the article or panel the necessary hardness and surface resistance.
- Such a molded article or panel thus has a fire resistance much higher than that of the molded articles or panels of the prior art.
- Such an article or panel is particularly particularly suitable for forming fire partitions and / or doors and fire panels, in particular inside buildings and constructions.
- the hard outer layer 3, whether it is based on resin or on a chemical binder, is deposited on the body 1 after the binder of the composition from which the body 1 is made has set.
- the fire-fighting properties of the panel are due to the composition in itself known of the molded body 1.
- 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.
- 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.
- the resin layer may have a small thickness, for example of the order of 0.5 or 1 mm, sufficient to give the article the hardness and the surface resistance necessary to resist the stresses associated with the use of a such article, shocks, friction,
- a small thickness for example of the order of 0.5 or 1 mm, sufficient to give the article the hardness and the surface resistance necessary to resist the stresses associated with the use of a such article, shocks, friction,
- the temperature rise of the panel is delayed in particular due to the release of the molecules of water of crystallization from the compound containing such molecules and from a possible chemical binder, as well as from those which can be contained in the block or blocks 2, which is done at a relatively low temperature.
- the molecules of water of crystallization of a possible hydraulic binder are released at a temperature higher than the previous one.
- the resin layer 3 prevents the water molecules from escaping outside.
- fusible fibers contained in the resin create by melting channels or pores which make the resin permeable to water vapor and allow the exit of this vapor while braking it if necessary.
- the panels according to the invention can of course be molded in the form of sleeves or half-shells to protect, for example, pipes.
