29-33 route de Rombas F-57140 WOIPPY/FRANCE pour: "Procédé et revêtement pour protéger les constructions contre le feu, le bruit et la chaleur"29-33 route de Rombas F-57140 WOIPPY / FRANCE for: "Process and coating to protect buildings against fire, noise and heat"
La présente invention concerne un procédé et un revêtement pour protéger les constructions spatiales, terrestres ou flottantes notamment contre le feu, le bruit et la chaleur.The present invention relates to a method and a coating for protecting space, land or floating constructions, in particular against fire, noise and heat.
Pour protéger les constructions précitées contre les effets du feu, du bruit et de la chaleur, on a déjà utilisé couramment des produits à base de diverses fibres minérales, notamment de fibres d'amiante éventuellement enrobées dans un liant organique ou inorganique. Ces produits pouvant également comporter des particules réfractaires ainsi que des fondants et/ou des charges contenant de l'eau de cristallisation ainsi que cela est décrit dans le brevet français 2458519.To protect the abovementioned constructions against the effects of fire, noise and heat, products based on various mineral fibers, in particular asbestos fibers, possibly coated in an organic or inorganic binder, have already been commonly used. These products may also include refractory particles as well as fluxes and / or fillers containing water of crystallization as described in French patent 2458519.
Toutefois, aucun des produits connus devant protéger les constructions n'offre le triple avantage de pouvoir conforter sa solidité pendant et/ou après sa mise en place, de pouvoir si nécessaire provoquer la modification de sa texture et d'augmenter de manière notable sa classification de résistance au feu.However, none of the known products which have to protect constructions offers the triple advantage of being able to reinforce its solidity during and / or after its installation, of being able if necessary to cause the modification of its texture and to significantly increase its classification. fire resistance.
Le but de la présente invention est de remédier aux inconvénients des revêtements de protection des constructions permettant d'obtenir un revêtement particulièrement résistant au feu, qui a un bon coefficient d'isolation phonique, thermique et acoustique et qui offre une grande résistance aux dégradations auxquelles sont habituellement soumis ces types de revêtement.The object of the present invention is to remedy the drawbacks of protective coatings for constructions, making it possible to obtain a coating which is particularly fire-resistant, which has a good coefficient of sound, thermal and acoustic insulation and which offers great resistance to damage to which are usually subject these types of coating.
De plus, cette invention offre la possibilité d'assainir lesdits revêtements en modifiant notamment leur structure fibreuse par l'attaque d'un produit basique approprié; cette attaque se traduit par une modification de la forme géométrique des fibres pouvant aller jusqu'à les transformer en poudre.In addition, this invention offers the possibility of sanitizing said coatings, in particular by modifying their fibrous structure by attacking an appropriate basic product; this attack results in a modification of the geometric shape of the fibers which can go so far as to transform them into powder.
Le revêtement, pour protéger les constructions, comprend des particules plus ou moins réfractaires fibreuses et/ou en grains enrobées d'un liant organique et/ou inorganique selon le degré de résistance au feu, selon le coefficient d'isolation thermique, acoustique et phonique désiré.The coating, to protect the constructions, includes more or less refractory fibrous and / or granular particles coated with an organic and / or inorganic binder according to the degree of fire resistance, according to the coefficient of thermal, acoustic and sound insulation longed for.
Nous allons expliquer l'objet de l'invention par les exemples suivants:We will explain the object of the invention by the following examples:
Lorsqu'un revêtement existant comporte déjà un composé chimique présentant la propriété d'augmenter son nombre de molécules d'eau de constitution, et que l'on le sature par pulvérisation avec l'une des formulations aqueuses suivantes, objet de l'invention, on obtient un surplus en eau de cristallisation de l'ensemble et une augmentation notable du degré de dureté dans la masse dudit revêtement.When an existing coating already comprises a chemical compound having the property of increasing its number of water molecules of constitution, and when it is saturated by spraying with one of the following aqueous formulations, object of the invention, there is obtained a surplus of water of crystallization of the assembly and a notable increase in the degree of hardness in the mass of said coating.
En effet, le silanol (CH3) SiOH additionné de silicate de soude, Si03Na2 et, suivant les nécessités de vitesse de prise, d'acide phosphorique, H3P04 jouant le rôle de catalyseur, le silanol se condense et se transforme en siloxane (CH3)2SiO + (11%) H2O. On a de ce fait également augmenté la tenue au feu du revêtement ci-dessus décrit.Indeed, the silanol (CH3) SiOH added with sodium silicate, Si03Na2 and, according to the needs of setting speed, phosphoric acid, H3P04 playing the role of catalyst, the silanol condenses and transforms into siloxane (CH3) 2SiO + (11%) H2O. This has also increased the fire resistance of the coating described above.
La vitesse de condensation est également rapide dans le cas où l'on mélange du diméthyl-silicans-diol et du silicate de soude Si03Na2 de module approprié, ou à l'aide d'un gel de silice. La combinaison de ces deux molécules donne 1/2 Na20-CH3-Si0^^5 1/2 H20. La combinaison de ces deux molécules a pour résultat qu'elles gélifient très rapidement en présence d'acide fort, par exemple, de l'acide phosphorique ou d'un acide carboxylé mélangé à de l'alcool en donnant une bonne stabilisation de la laine.The speed of condensation is also rapid in the case where dimethyl-silicans-diol and sodium silicate Si03Na2 of appropriate module are mixed, or using a silica gel. The combination of these two molecules gives 1/2 Na20-CH3-Si0 ^^ 5 1/2 H20. The combination of these two molecules results in that they gel very quickly in the presence of strong acid, for example, phosphoric acid or a carboxylated acid mixed with alcohol, giving good stabilization of the wool. .
Avec le disilane ou le silane (CH3)2SiO additionné de soude caustique NaOH dont la combinaison des deux molécules donne Na(CH3)^SiOH^O, on constate que la soude caustique à elle seule apporte 22% d'eau de cristallisation et que l'ensemble donne une très bonne cohésion au revêtement qui suivant la dose de soude caustique fera disparaître les fibres.With the disilane or the silane (CH3) 2SiO added with caustic soda NaOH whose combination of the two molecules gives Na (CH3) ^ SiOH ^ O, one notes that the caustic soda alone brings 22% of water of crystallization and that the whole gives a very good cohesion to the coating which, depending on the dose of caustic soda, will make the fibers disappear.
