3032909 2 Dichos elementos estât-1 constituidos, entre otros componentes, esencialmente de fibras de vidrio que constituyen una lana minerai. Por lo general los productos existentes para la fabricaciôn de conductos de aire basados en lana minerai obtienen una reacciôn al fuego que se encuentra entre las 5 clases A2-s1,d0 (no combustible; sin contribuciôn en grado menor al fuego) o B-s1,d0 (combustible; contribuciôn muy limitada al fuego) La lana minerai tiene como referencia de medida el "indice de finura" o "medida del MICRONAIRE". Esta medida se describe en la norma ASTM D1448 (asi como en DIN 53941); se ha desarrollado inicialmente para caracterizar las fibras de algodém y, 10 desde hace tiempo, se utiliza en la industria de la fibra minerai para caracterizar las fibras de vidrio. Se define el "indice de finura" por el valor leido en el aparato "MICRONAIRE" para una masa dada de producto. La medida obtenida por dicho aparato se corresponde con el valor obtenido midiendo la pérdida de carga de un gas que atraviesa una muestra constituida con las fibras a caracterizar, dando asi, esta 15 medida, una indicaciôn del diàmetro medio de las fibras. Un indice de finura alto de las fibras, por ejemplo que esté en 5,8 ± 0,5, por lo general, dotan al producto de resistencia a la compresiôn por lo que se puede reducir el encolado, pero lo hacen fragil a la flexiôn y al no tener resistencia a la flexiôn se puede romper mas facilmente durante su manipulaciôn. Por el contrario, indices que oscilen 20 entre 4,2 ± 0,5 en las fibras dotan al producto de mas resistencia a la flexiôn; por eso es este rango el mas habituai en este tipo de elementos de construcciôn. La fibras de la lana minerai, para este tipo de productos, estât-1 encoladas o dicho de modo, se adiciona adhesivo para que las fibras conformen dicha lana minerai. Es conocido que una proporciôn de encolado respecto al peso total de la fibra alto, por 25 ejemplo por encima del 8%-10%, conduce a una mata clasificaciôn en lo que se refiere a la reacciôn frente al fuego de los conductos de aire que lo comprenden (A2, B o menor); mientras que una proporciôn mas baja de aglomerante por si solo (leva a que el producto final sea débit. Es conocido que los productos en el mercado para estas aplicaciones, de forma mayoritaria, presentan una proporciôn de encolado entorno al 8%. La patente espahola ES-2169005-B1 muestra un conducto de lana minerai que consiste en un nùcleo de lana minerai formado por fibras de vidrio que componen la 3032909 3 lana alcanzando un indice de finura o (MICRONAIRE) que oscila entre 5,8 ± 0,5 sobre 6 gramos, al cual se adiciona material adhesivo en torno al 5% y el 6%. El documento US-5968645 describe un producto a base de fibras minerales, que tiene diâmetros de fibras de aproximadamente 6 a 10 pm, y una cantidad de aglomerante de 5 especialmente 2 a 20% y, en el ejemplo, 4,5% en peso. La patente EP-1571247-B1 describe un material aislante a base de lana de vidrio, que tiene una finura (MICRONAIRE) comprendida entre 2,2 y 3,1 para 5 gramos, y una cantidad de adhesivo comprendida entre 1 y 4,5% en peso. El documento US-5728187 describe un producto a base de fibras minerales que tienen 10 diâmetros de 0,76 a 1,04 pm y una cantidad de adhesivo de 12 a 17% en peso. Por otro lado, este tipo elementos basados en lana minerai pueden incorporar un papel de recubrimiento, que puede ser de tipo kraft aluminio o aluminio reforzado pero dicho pape) no favorece una buena clasificaciôn respecto al fuego.3032909 2 Dichos elementos estât-1 constituidos, between otros componentes, esencialmente of fibras of vidrio that constituyen una lana ore. In general, the productos exist for the manufacture of area conductos basados in the ore obtienen a reacciôn al fuego that encuentra between the 5 classes A2-s1, d0 (no fuel, sin contribuciôn in grado menor al fuego) o B-s1 , d0 (fuel, contrib ute muy limitada al fuego) The lana ore has a como referencia de medida and "finite index" o "medida del MICRONAIRE". Esta medida is described in ASTM standard D1448 (asi como in DIN 53941); First of all it is necessary to characterize the fibras of algodém y, 10 desde hace tiempo, is used in the industria of fibra mineral para caracterizar las fibras de vidrio. To define the "finite index" for the leido value in the aparato "MICRONAIRE" para una masa dada de producto. The medida getida por dicho aparato corresponds to the valor obtained midiendo the perdida de carga of a gas that atraviesa una muestra constituidas con las fibras a caracterizar, dando asi, esta 15 medida, a indicaciôn del diàmetro medio de las fibras. An index of finite alto de las fibras, for which it is estimated in 5.8 ± 0.5, for the general, dotan al producto of resistencia to the compresión por lo that can puede reducir el encolado, pero lo hacen fragil a flexiôn There is no resistance to flexion, which can easily be broken by manipulación. For the contrario, indices that oscillate between 4.2 ± 0.5 in the fibras dotan al producto of mas resistance to flexion; por eso es este rango el mas accustomed to this type of elementos de construcciôn. The fibras of the mineral ore, for this type of product, are one or more of the modo dicho, adiciona adhesivo para las fibras conformen dicha lana ore. It is conocido that a proportion of total respect of the fibra viola, for 25% of 8% -10%, conduce to a mata clasificación in lo that is refere to the frente al fuego of the conductos de aire that lo understands (A2, B o menor); It is important that a proportion of the aglomerante por baja por si solo (leva that the producto final sea flow.) Conocido that the productos in the mercado para estas aplicaciones, of forma mayoritaria, presentan a proportion of encolado entorno al 8%. ES-2169005-B1 will muestra a conducto of the ore that consists of a nickel of the ore formado por fibras de vidrio that the component 3032909 3 lana alcanzando an index of finite o (MICRONAIRE) that oscila between 5.8 ± 0.5 sober 6 gramos, al cual adiciona material adhesivo en torno al 5% y el 6% El documento US-5968645 describes a producto based on mineral fibras, that supports fiber sizes of aproximadamente 6 to 10 pm, and a cantidad of aglomerante from 5 to 20%, in particular 4.5% in peso Patent EP-1571247-B1 describes a material based on vinyl film, which has a fina (MICRONAIRE) between 2,2 y 3,1 para 5 gramos, there is a cantidad de adhesivo comprisida entr e 1 y 4.5% in peso. Document US-5728187 describes a product based on inorganic fibras that have a diameter of 0.76 to 1.04 μm and an adhesiveness rate of 12 to 17% in peso. Por otro lado, este tipo elements basados en lana ore pueden incorporar a papel of recubrimiento, que puede ser de tipo kraft aluminio o aluminio reforzado pero dicho pape) no favorece una buena clasificaciôn respecto al fuego.

20 Es necesario ofrecer una alternativa al estado de la técnica que cubra las lagunas encontradas en la misma, y de forma particular un elemento con nùcleo de lana minerai con reacciôn reforzada al fuego y conducto de aire que comprende dicho elemento que permita alcanzar una clase de clasificaciôn de Al de resistencia al fuego, es decir, la mas exigente, no combustible y sin contribuciôn en grado mâximo al 25 fuego. Con este fin, la presente invenciôn se refiere en un primer aspecto a un elemento con reacciôn al fuego mejorada constituido por un nùcleo de lana minerai, un veto y un recubrimiento de aluminio estando dicho nùcleo de lana minerai compuesto de por fibras de vidrio a las que se ahade un aglomerante y estando dicho recubrimiento de 30 aluminio adherido a la lana minerai por un adhesivo caracterizado porque es ahadido 3032909 4 revêtement d'aluminium, ledit noyau en laine minérale étant composé de fibres de verre auxquelles on ajoute un agglomérant et ledit revêtement d'aluminium étant collé à la laine minérale par un adhésif caractérisé en ce qu'on l'ajoute dans une quantité qui varie entre 10 et 25 g/m2 de la surface à coller et de préférence dans une quantité qui 5 varie autour de 20 ± 0,5 g/m2 de surface de collage. Lesdites fibres de verre présentent un indice de finesse qui varie autour de 4,2 ± 0,5 pour 6 grammes et la proportion d'agglomérant varie entre 4,8% et 5,8%. Dans un mode de réalisation préféré de l'invention l'élément avec réaction renforcée au feu se présente sous forme de panneau pour être utilisé dans la construction de 10 conduits d'air. Les fibres de verre de l'élément selon l'invention ont un indice de finesse qui varie autour de 4,2 ± 0,5 quand on introduit une quantité de fibres correspondant à une masse de 6 grammes dans la cellule de mesure de l'appareil "MICRONAIRE". Pour fixer un ordre de grandeur, on peut dire qu'un indice de finesse de 4,2 ± 0,2 pour 6 15 grammes correspond à la caractérisation des fibres de verre dont le diamètre moyen est d'environ 3,5 à 4 pm. Dans un mode de réalisation préféré de l'invention, la densité de la laine minérale varie autour de 60 ± 10 kg/m3, de préférence autour de 65 ± 5 kg/m3. Pour unir entre elles les fibres de verre de la laine minérale on utilise un composé de 20 collage ou adhésif qui, à la différence d'autres panneaux existants, se situe dans une plage de 4,8% à 5,8% du poids total de la laine minérale. Ladite proportion est une caractéristique clé dans l'ensemble du calcul pour, conformément aux normes existantes en rapport avec la résistance au feu, atteindre la classification maximale, comme par exemple la classe Al selon la norme UNE-EN 13501-1.20 Es necesario ofrecer una alternativa al estado de la técnica that cubra las lagunas encontradas en la misma, y de forma peculiar an elemento con nùcleo de lana ore con reacciôn reforzada al fuego y conducto de aire that includes dicho elemento that permita alcanzar una clase de clasificación de Al de resistencia al fuego, es decir, the mas requires, noncombustible y sin contribuciôn in grado maximo al 25 fuego. In the end, the present invention is a primitive aspect to an element that has been developed as part of a mineral cycle, a veto and a recovery of aluminio estando dicho uncleo of the ore compuesto de fibras de vidrio a las. that an aglomerante y estando dicho recubrimiento de aluminio adherido a la lana ore for a adhesivo caracterizado porque es ahadido 3032909 4 aluminum coating, said mineral wool core being composed of glass fibers to which one adds a binder and said coating of aluminum being adhered to the mineral wool by an adhesive characterized in that it is added in an amount which varies between 10 and 25 g / m 2 of the surface to be bonded and preferably in an amount which varies around 20 ± 0.5 g / m2 bonding area. Said glass fibers have a fineness index which varies around 4.2 ± 0.5 for 6 grams and the proportion of agglomerator varies between 4.8% and 5.8%. In a preferred embodiment of the invention the fire-reinforced element is in the form of a panel for use in the construction of air ducts. The glass fibers of the element according to the invention have a fineness index which varies around 4.2 ± 0.5 when a quantity of fibers corresponding to a mass of 6 grams is introduced into the measuring cell of the device "MICRONAIRE". To set an order of magnitude, we can say that a fineness index of 4.2 ± 0.2 for 6 15 grams corresponds to the characterization of glass fibers whose average diameter is about 3.5 to 4 pm . In a preferred embodiment of the invention, the density of the mineral wool varies around 60 ± 10 kg / m3, preferably around 65 ± 5 kg / m3. In order to join together the glass fibers of the mineral wool, a glue or adhesive compound is used which, unlike other existing panels, is in a range of 4.8% to 5.8% of the total weight. mineral wool. This proportion is a key feature in the overall calculation for, in accordance with existing fire-related standards, reaching the maximum classification, such as Al class according to UNE-EN 13501-1.
25 Selon un mode de réalisation préféré, le produit de collage pour unir les fibres de verre de la laine minérale est un agglutinant obtenu à partir d'une résine organique. Dans un autre mode de réalisation préféré, principalement quand l'élément se présente sous forme de panneau, le revêtement par voile s'intègre à un des côtés dudit panneau, ledit voile étant, dans un mode de réalisation préféré, fabriqué avec de la 30 fibre de verre renforcée.
