DESCRIPTION

Panel de lana mineral Mineral wool panel

5 Esta invención se refiere a un panel de aislamiento de lana mineral, en particular para su uso en puertas cortafuegos. 5 This invention relates to a mineral wool insulation panel, in particular for use in fire doors.

El documento EP1533462A se refiere a una construcción para una puerta cortafuegos y divulga el uso de una pluralidad de paneles de aislamiento de lana mineral dentro de la cavidad de la puerta, teniendo cada panel de lana mineral una densidad y/o una cantidad de retardantes del fuego diferentes. Esto está concebido para optimizar el aislamiento para que corresponda a las tensiones de temperatura variables a lo largo de la altura de la puerta. Una desventaja de esta disposición es la necesidad de suministrar y ensamblar diferentes paneles de lana mineral individuales. EP1533462A refers to a construction for a fire door and discloses the use of a plurality of mineral wool insulation panels within the door cavity, each mineral wool panel having a density and / or an amount of retardants of the different fire. This is designed to optimize the insulation to correspond to the variable temperature stresses along the height of the door. A disadvantage of this arrangement is the need to supply and assemble different individual mineral wool panels.

15 Un objetivo de la presente invención es facilitar el suministro y el ensamblaje de paneles de lana mineral, particularmente para puertas cortafuegos. Otro objetivo es mitigar el riesgo de puntos débiles de disposiciones anteriores de paneles de aislamiento para puertas cortafuegos al tiempo que se optimiza el uso del material. An object of the present invention is to facilitate the supply and assembly of mineral wool panels, particularly for fire doors. Another objective is to mitigate the risk of weak points from previous arrangements of insulation panels for fire doors while optimizing the use of the material.

De acuerdo con un aspecto, la presente invención proporciona un panel de aislamiento de lana mineral como se define en la reivindicación 1. Otros aspectos se definen en otras reivindicaciones dependientes aunque las reivindicaciones dependientes definen realizaciones preferidas y/o alternativas. According to one aspect, the present invention provides a mineral wool insulation panel as defined in claim 1. Other aspects are defined in other dependent claims although the dependent claims define preferred and / or alternative embodiments.

La provisión de un panel de aislamiento de lana mineral de una sola pieza que tiene una altura de al menos 160 cm y una anchura de al menos 60 cm permite que el panel se use sin requerir paneles adicionales para llenar la cavidad 25 de una puerta cortafuegos. Manejar y ensamblar un solo panel es más fácil y más eficiente que tratar con múltiples paneles diferentes. Además, la provisión de un panel único o unitario que tiene dimensiones que pueden llenar toda la cavidad de una puerta evita el riesgo de un punto de debilidad o de un puente térmico en el aislamiento que podría ocurrir en los estribos de paneles separados pero contiguos. El panel puede ser sustancialmente rectangular; puede estar provisto de cortes preformados y/o de recortes para facilitar su ensamblaje en una cavidad de la puerta. The provision of a single piece mineral wool insulation panel having a height of at least 160 cm and a width of at least 60 cm allows the panel to be used without requiring additional panels to fill the cavity 25 of a fire door . Handling and assembling a single panel is easier and more efficient than dealing with multiple different panels. In addition, the provision of a single or unitary panel having dimensions that can fill the entire cavity of a door avoids the risk of a weakness point or a thermal bridge in the insulation that could occur in the stirrups of separate but contiguous panels. The panel can be substantially rectangular; It can be provided with preformed cuts and / or cutouts to facilitate its assembly in a door cavity.

Las dimensiones del panel pueden ser: The dimensions of the panel can be:

• •: altura ≥160 cm, opcionalmente ≥180cm o ≥200 cm y/o ≤260 cm, opcionalmente ≤240 cm o ≤230 cm; height ≥160 cm, optionally ≥180cm or ≥200 cm and / or ≤260 cm, optionally ≤240 cm or ≤230 cm;

• •: anchura ≥60 cm, opcionalmente ≥70cm o ≥80 cm y/o ≤150 cm, opcionalmente ≤120cm o ≤100 cm; width ≥60 cm, optionally ≥70cm or ≥80 cm and / or ≤150 cm, optionally ≤120cm or ≤100 cm;

35 • espesor preferentemente ≥1,5 cm, opcionalmente ≥3cm o ≥4 cm y/o preferentemente ≤12 cm, opcionalmente ≤10 cm o ≤8 cm 35 • thickness preferably ≥1.5 cm, optionally ≥3cm or ≥4 cm and / or preferably ≤12 cm, optionally ≤10 cm or ≤8 cm

Las tensiones térmicas a las que se somete una puerta durante un incendio o durante un ensayo de incendio no son constantes a lo largo de la altura de la puerta. La configuración de las bandas inferior, central y superior en el panel de aislamiento permite que las bandas superior y/o inferior estén dispuestas con una mayor densidad deseada de aislamiento de lana mineral para lograr la resistencia al fuego y/o el rendimiento térmico deseados sin el uso de la misma alta densidad en la banda central. Esto reduce el peso total y, por lo tanto, el coste del panel de lana mineral en comparación con un panel único que tiene una densidad homogénea de la densidad de las bandas superior y/o inferior. En una realización preferida, la densidad en las bandas superior e inferior es sustancialmente la misma y/o The thermal stresses to which a door is subjected during a fire or during a fire test are not constant along the height of the door. The configuration of the lower, central and upper bands in the insulation panel allows the upper and / or lower bands to be arranged with a higher desired density of mineral wool insulation to achieve the desired fire resistance and / or thermal performance without the use of the same high density in the central band. This reduces the total weight and, therefore, the cost of the mineral wool panel compared to a single panel having a homogeneous density of the density of the upper and / or lower bands. In a preferred embodiment, the density in the upper and lower bands is substantially the same and / or

45 el panel de lana mineral es sustancialmente simétrico alrededor de su eje horizontal central; esto permite que el panel se use en una cavidad de la puerta en cualquier dirección y por lo tanto facilita el ensamblaje. La porción más crítica de una puerta por su resistencia o comportamiento al fuego es generalmente una banda a lo largo de la anchura de la puerta en o hacia su borde superior y/o una banda a lo largo de la anchura de la puerta en o hacia su borde inferior. El panel de acuerdo con la presente invención proporciona así una alta densidad de aislamiento de lana mineral que se proporcionará en estas áreas mientras se usa una menor densidad de lana mineral en una banda central a lo largo de la anchura de la puerta en la que dicha alta densidad sería innecesaria. The mineral wool panel is substantially symmetrical around its central horizontal axis; This allows the panel to be used in a door cavity in any direction and therefore facilitates assembly. The most critical portion of a door because of its resistance or fire behavior is generally a band along the width of the door at or towards its upper edge and / or a band along the width of the door at or towards its lower edge. The panel according to the present invention thus provides a high density of mineral wool insulation that will be provided in these areas while a lower density of mineral wool is used in a central band along the width of the door in which said High density would be unnecessary.

En otra realización preferida, la densidad en la banda inferior es menor que la densidad en la banda central, y la densidad en la banda central es menor que la densidad en la banda superior; esto proporciona una optimización útil In another preferred embodiment, the density in the lower band is less than the density in the central band, and the density in the central band is less than the density in the upper band; this provides a useful optimization

55 de la cantidad de aislamiento de lana mineral utilizada en el panel al tiempo que proporciona una densidad deseada de aislamiento de lana mineral en la banda superior, por ejemplo para lograr una clasificación de resistencia al fuego deseada. Cada una de las bandas superior e inferior puede tener una altura ≥5 cm, preferentemente ≥10 cm, más preferentemente ≥15 cm y/o ≤60 cm, preferentemente ≤40 cm, más preferentemente ≤30 cm. Un borde de cada una de las bandas superior y/o inferior puede estar situado respectivamente en el borde superior e inferior del panel. La densidad de la lana mineral en cada una o en cualquiera de las bandas superior, central e inferior no precisa ser homogénea. De hecho, la transición de la densidad entre las bandas superior y/o inferior y la banda central es preferentemente gradual en lugar de ser un cambio radical de la densidad. 55 of the amount of mineral wool insulation used in the panel while providing a desired density of mineral wool insulation in the upper web, for example to achieve a desired fire resistance rating. Each of the upper and lower bands may have a height ≥5 cm, preferably ≥10 cm, more preferably ≥15 cm and / or ≤60 cm, preferably ≤40 cm, more preferably ≤30 cm. An edge of each of the upper and / or lower bands may be located respectively on the upper and lower edge of the panel. The density of mineral wool in each or in any of the upper, central and lower bands does not need to be homogeneous. In fact, the transition of density between the upper and / or lower bands and the central band is preferably gradual rather than being a radical change in density.

La densidad en cada una de las bandas superior e inferior puede ser ≥100 kg/m3, preferentemente ≥120 kg/m3, más 65 preferentemente ≥140 kg/m3 y/o ≤220 kg/m3, preferentemente ≤250 kg/m3, más preferentemente ≤300 kg/m3. Con respecto a la invención definida en la reivindicación 1, la densidad del aislamiento de lana mineral en cada una de las bandas superior e inferior está dentro del intervalo de 100 a 300 kg/m3. La densidad en la banda central puede ser ≥60 kg/m3, preferentemente ≥80 kg/m3, más preferentemente ≥100 kg/m3 y/o ≤180 kg/m3, preferentemente ≤210 kg/m3, más preferentemente ≤250 kg/m3. Dado que la densidad en cada banda no precisa ser homogénea, la The density in each of the upper and lower bands may be ≥100 kg / m3, preferably ≥120 kg / m3, more preferably 65 ≥140 kg / m3 and / or ≤220 kg / m3, preferably ≤250 kg / m3, more preferably ≤300 kg / m3. With respect to the invention defined in claim 1, the density of mineral wool insulation in each of the upper and lower bands is within the range of 100 to 300 kg / m3. The density in the central band may be ≥60 kg / m3, preferably ≥80 kg / m3, more preferably ≥100 kg / m3 and / or ≤180 kg / m3, preferably ≤210 kg / m3, more preferably ≤250 kg / m3. Since the density in each band does not need to be homogeneous, the

5 densidad de una banda puede determinarse tomando tres muestras cada una con dimensiones de aproximadamente 10 cm x 10 cm en ubicaciones a lo largo de una sola línea sustancialmente paralela al borde superior o inferior del panel a lo largo de la anchura del panel y determinando la densidad media de estas tres muestras. The density of a band can be determined by taking three samples each with dimensions of approximately 10 cm x 10 cm at locations along a single line substantially parallel to the top or bottom edge of the panel along the width of the panel and determining the Average density of these three samples.

La densidad en la banda superior y/o en la banda central y/o en la banda inferior puede ser sustancialmente constante a lo largo de toda la anchura del panel en esa banda. Por ejemplo, la densidad en dicha(s) banda(s) a lo largo de toda la anchura del panel puede estar dentro del intervalo de ±10 kg/m3 o ±5 kg/m3 con respecto a la densidad media en la banda en cuestión, dicha densidad media y variación en la densidad en una banda se determinan tomando un número representativo de muestras, cada una con dimensiones de aproximadamente The density in the upper band and / or in the central band and / or in the lower band can be substantially constant along the entire width of the panel in that band. For example, the density in said band (s) along the entire width of the panel may be within the range of ± 10 kg / m3 or ± 5 kg / m3 with respect to the average density in the band in question, said average density and variation in the density in a band are determined by taking a representative number of samples, each with dimensions of approximately

15 10 cm x 10 cm en ubicaciones a lo largo de una sola línea dentro de la banda sustancialmente paralela al borde superior o inferior del panel a lo largo de toda la anchura del panel. 15 10 cm x 10 cm at locations along a single line within the band substantially parallel to the top or bottom edge of the panel along the entire width of the panel.

La densidad del aislamiento de lana mineral en cada una de las bandas superior e inferior puede ser mayor que la densidad del aislamiento de lana mineral en la banda central en al menos un 8 %, más preferentemente en al menos un 12 % e incluso más preferentemente en al menos un 15 %. The density of mineral wool insulation in each of the upper and lower bands may be greater than the density of mineral wool insulation in the central band by at least 8%, more preferably at least 12% and even more preferably at least 15%.

Una posición en una puerta cortafuegos que puede considerarse crítica en términos de su comportamiento al fuego es la posición hacia una esquina de la puerta separada 10 cm de cada uno de los bordes adyacentes en esa esquina. En consecuencia, se prefiere que cada posición del panel de aislamiento de lana mineral esté situada A position in a fire door that can be considered critical in terms of its fire behavior is the position towards a corner of the door 10 cm apart from each of the adjacent edges in that corner. Consequently, it is preferred that each position of the mineral wool insulation panel is located

25 dentro de una de las bandas superior o inferior. 25 within one of the upper or lower bands.

La lana mineral es preferentemente lana de roca; alternativamente puede ser lana de vidrio. Cuando la lana mineral comprende un aglutinante, este puede estar presente en una cantidad de ≥0,5 % en peso, preferentemente ≥0,8 % en peso, y/o ≤4 % en peso, preferentemente ≤3% en peso, expresado en % en peso con respecto a la lana mineral incluyendo el aglutinante y medida, por ejemplo, por pérdidas por ignición. Tal aglutinante es preferentemente un aglutinante orgánico curado térmicamente, por ejemplo un aglutinante de fenol formaldehido, un aglutinante de urea formaldehido o un aglutinante basado en hidratos de carbono, aplicado a la fibra mineral entre su formación y su recogida juntos como una estera primaria. En algunas realizaciones, el panel está libre de aglutinante o sustancialmente libre de aglutinante. La lana mineral puede representar al menos el 85 %, al menos el 90 %, al The mineral wool is preferably rock wool; alternatively it can be glass wool. When the mineral wool comprises a binder, it may be present in an amount of ≥0.5% by weight, preferably ≥0.8% by weight, and / or ≤4% by weight, preferably ≤3% by weight, expressed in% by weight with respect to mineral wool including the binder and measured, for example, by ignition losses. Such binder is preferably a thermally cured organic binder, for example a phenol formaldehyde binder, a urea formaldehyde binder or a carbohydrate based binder, applied to the mineral fiber between its formation and its collection together as a primary mat. In some embodiments, the panel is free of binder or substantially free of binder. Mineral wool can represent at least 85%, at least 90%, at

35 menos el 94 %, al menos el 96 % o al menos el 98 % en peso del panel de aislamiento de lana mineral. 35 minus 94%, at least 96% or at least 98% by weight of the mineral wool insulation panel.

El panel es particularmente adecuado para su uso en puertas, particularmente en puertas cortafuegos y aún más particularmente en puertas que cumplen con las clasificaciones de resistencia al fuego EI 30, EI 40, EI 60, EI 90 o EI 120. Las puertas pueden comprender un revestimiento periférico, que comprende preferentemente chapa metálica, en particular de acero, que define una cavidad interna de la puerta en la que está dispuesto el panel de lana mineral. The panel is particularly suitable for use in doors, particularly in fire doors and even more particularly in doors that meet the fire resistance classifications EI 30, EI 40, EI 60, EI 90 or EI 120. The doors can comprise a peripheral coating, preferably comprising metal sheet, in particular steel, which defines an internal cavity of the door in which the mineral wool panel is arranged.

Una banda superior 21, una banda central 23 y una banda inferior 22 se extienden cada una a lo largo de la anchura del panel 10. En la realización ilustrada en la figura 1 y en la figura 2, cada una de las bandas superior 21 e inferior 22 tiene una mayor densidad de lana mineral que la banda central 23. La densidad del aislamiento de lana mineral en la dirección de la altura h no es homogénea, varía gradualmente, y las zonas de transición 24, 25 también de densidad gradualmente variable separan cada una de las bandas superior e inferior 21,22 de la banda central 23. Puede tomarse una densidad representativa de cada banda como la densidad media a lo largo de las líneas de muestra imaginarias superior 31, inferior 32 y central 33 situadas respectivamente dentro de cada banda y que 65 discurren a lo largo de la anchura w del panel paralelas a los bordes superior e inferior 11, 12, estando situada la línea de muestra central preferentemente a mitad de camino entre el borde superior 11 y el borde inferior 12 del An upper band 21, a central band 23 and a lower band 22 each extend along the width of the panel 10. In the embodiment illustrated in Figure 1 and Figure 2, each of the upper bands 21 e lower 22 has a higher density of mineral wool than the central band 23.

10 mineral, a las que preferentemente se ha aplicado un aglutinante curable térmicamente, se transfieren en forma de una estera primaria 61 que tiene un peso sustancialmente homogéneo por unidad de superficie a lo largo de toda su anchura w1 desde una cinta de recogida 62 a un transportador de esteras primario 63 que avanza en una primera dirección 64. Se utiliza un mecanismo de péndulo oscilante 66 para transferir la estera primaria 61 a un transportador de esteras secundario 68 que avanza en una dirección 69 sustancialmente perpendicular al Mineral, to which a thermally curable binder has preferably been applied, is transferred in the form of a primary mat 61 having a substantially homogeneous weight per unit area along its entire width w1 from a collection tape 62 to a primary mat conveyor 63 that advances in a first direction 64. A swing pendulum mechanism 66 is used to transfer the primary mat 61 to a secondary mat conveyor 68 that advances in a direction 69 substantially perpendicular to the

15 transportador de esteras primario 63 para formar una estera secundaria 70 por plegado recíproco de la estera primaria 61. La velocidad del péndulo hacia al menos uno de los vértices de su movimiento está dispuesta para ser diferente, por ejemplo, más baja que la velocidad del péndulo en su posición central; de esta manera, con el transportador de esteras secundario 68 avanzando a una velocidad sustancialmente constante, se deposita una cantidad diferente, por ejemplo, una cantidad mayor (peso por unidad de superficie) de la estera primaria 61 en uno 15 primary mat conveyor 63 to form a secondary mat 70 by reciprocal folding of the primary mat 61. The speed of the pendulum towards at least one of the vertices of its movement is arranged to be different, for example, lower than the velocity of the pendulum in its central position; thus, with the secondary mat conveyor 68 advancing at a substantially constant speed, a different amount is deposited, for example, a larger amount (weight per unit area) of the primary mat 61 in one

20 o ambos bordes laterales 71, 72 en las extremidades de la anchura w2 de la estera secundaria 70 que se deposita en la posición central 73 a lo largo de la anchura w2 de la estera secundaria 70. 20 or both side edges 71, 72 at the ends of the width w2 of the secondary mat 70 which is deposited in the central position 73 along the width w2 of the secondary mat 70.

En una etapa posterior (no ilustrada), la estera secundaria se comprime, su aglutinante (cuando está presente) se cura en un horno de curado y sus bordes 71, 72 preferentemente se recortan. At a later stage (not illustrated), the secondary mat is compressed, its binder (when present) is cured in a curing oven and its edges 71, 72 are preferably trimmed.

25 Ventajosamente, la anchura w2 de la estera secundaria 70 está dispuesta para ser sustancialmente la misma que la altura deseada h del panel de aislamiento de lana mineral 10, de modo que después de cualquier recorte de borde de la estera, la estera se corte a lo largo de su anchura w2 para formar el panel de aislamiento de lana mineral 10, convirtiéndose así la anchura w2 de la estera en la altura h del panel. De esta manera, hay poco o ningún residuo Advantageously, the width w2 of the secondary mat 70 is arranged to be substantially the same as the desired height h of the mineral wool insulation panel 10, so that after any cutting of the edge of the mat, the mat is cut to along its width w2 to form the mineral wool insulation panel 10, thus converting the width w2 of the mat into the height h of the panel. In this way, there is little or no residue
