PROCEDIMIENTO DE EXTINCIÓN DE INCENDIOS FIRE EXTINGUISHING PROCEDURE
DESCRIPCIÓNDESCRIPTION
OBJETO DE LA INVENCIÓNOBJECT OF THE INVENTION
La presente invención se refiere a un procedimiento de extinción activo de incendios mediante produc- tos intumescentes, es decir un procedimiento para ayudar a sofocar un incendio una vez que éste se ha producido.The present invention relates to a process of active fire extinguishing by intumescent products, that is to say a method to help quell a fire once it has occurred.
ANTECEDENTES DE LA INVENCIÓNBACKGROUND OF THE INVENTION
Los métodos de extinción de incendios se dividen en dos grandes grupos : métodos activos y métodos pasivos .Firefighting methods are divided into two large groups: active methods and passive methods.
Los métodos activos se caracterizan porque si el fuego se encuentra en una etapa inicial o tiene unas caracteristicas que permiten actuar en la proximidad de las llamas, se puede atacar directamente sobre el incen¬ dio para sofocar la llama, en estos métodos se desplaza violentamente el aire próximo al combustible o se enfria el combustible.Active methods are characterized in that if the fire is in an initial stage or has characteristics that allow act in the vicinity of the flames can directly attack on incen ¬ given to suppress the flame, in these methods it moves violently air near the fuel or the fuel cools.
En cuanto a los métodos pasivos lo que se persigue es crear medidas de defensa ante la posible aparición de un fuego.As for the passive methods, what is sought is to create defense measures against the possible appearance of a fire.
Los productos intumescentes han sido utilizados como métodos pasivos para proteger del fuego materiales combustibles o afectables por el calor.Intumescent products have been used as passive methods to protect combustible or heat-affected materials from fire.
Entre otras aplicaciones por ejemplo se han aplicado sobre superficies de acero de materiales estructurales como columnas y vigas de construcción de edificios. Habitualmente en un incendio el acero desprotegido alcanza la temperatura de colapso, es decir pierde su resistencia mecánica en pocos minutos. De acuerdo a la curva normalizada de temperatura-tiempo de un incendio, la temperatura critica del acero se alcanza aproximadamente a los cinco minutos y debido a la buena conductividad del acero los elementos no protegi- dos no tardan en alcanzarla, produciéndose rápidamente el riesgo de colapso. En la práctica, los colapsos se presentan entre 10 y 15 minutos de iniciado el fuego. En cambio cuando se ha aplicado un producto intumescente, este recubrimiento al sufrir el calor que se origina en el incendio, se expandirá formando una gruesa capa carbonosa y esponjosa, que aislará al acero del calor. El tiempo en que el acero llegue a la temperatura critica de colapsarse, será mucho mas prolongado, gracias al aislamiento producido por la capa intumescente.Among other applications for example have applied on steel surfaces of structural materials such as columns and beams of building construction. Usually in a fire the unprotected steel reaches the collapse temperature, that is, it loses its mechanical resistance in a few minutes. According to the normalized temperature-time curve of a fire, the critical temperature of the steel is reached at approximately five minutes and due to the good conductivity of the steel the unprotected elements do not take long to reach it, quickly producing the risk of collapse. In practice, collapses occur between 10 and 15 minutes after the fire starts. On the other hand, when an intumescent product has been applied, this coating, upon suffering the heat that originates in the fire, will expand forming a thick, spongy, carbonaceous layer, which will insulate the steel from heat. The time in which the steel reaches the critical temperature of collapsing will be much longer, thanks to the insulation produced by the intumescent layer.
Por ejemplo una patente donde se describe el uso de productos intumescentes como método indirecto de extinción de incendios es la patente EP1683841.For example, a patent describing the use of intumescent products as an indirect method of fire extinguishing is EP1683841.
Por lo tanto los productos intumescentes son conocidos como medio pasivo de protección de incendios.Therefore, intumescent products are known as passive means of fire protection.
Estos productos intumescentes conocidos están constituidos por, al menos cuatro ingredientes sinérgi- eos entre si:These known intumescent products consist of at least four synergistic ingredients with each other:
• un agente catalizador tal como el polifosfato amónico, el cual a temperatura de unos 200 °C liberará ácido polifosfórico,• a catalyst agent such as ammonium polyphosphate, which at a temperature of about 200 ° C will release polyphosphoric acid,
• un formador de carbón, tal como substancias orgáni- cas que reaccionan con el ácido polifosfórico, como el pentaeritrol o el dipentaeritrol,• a carbon former, such as organic substances that react with polyphosphoric acid, such as pentaerythrol or dipentaerythrol,
• un agente formador de gases inertes como la melani- na la cual producirá nitrógeno y amoniaco y expandirá la película, • agentes adhesivos como resinas acrilicas, epoxi, aminicas, siliconas.• an inert gas forming agent such as melanin which will produce nitrogen and ammonia and expand the film; • adhesive agents such as acrylic, epoxy, aminic resins, silicones.
Cuando los incendios son atajados por métodos activos se puede emplear generalmente agua, a la que se le añaden retardantes, estos es, aditivos que mezclados con el agua mejoran las propiedades intrínsecas del agua de extinción como las sales amónicas del grupo de los sulfatos, fosfatos o polifosfatos .When fires are stopped by active methods, water can generally be used, to which retardants are added, that is, additives that, mixed with water, improve the intrinsic properties of extinguishing water such as the ammonium salts of the sulfate group, phosphates or polyphosphates.
También se pueden utilizar espumógenos . La acción de los espumógenos dura hasta que el agua se evapora, en el momento en que se evapora el agua, los espumó- genos dejan de ser activos. Esta limitación no es presentada por los productos intumescentes .Foams can also be used. The action of the foaming agents lasts until the water evaporates, at the moment when the water evaporates, the foams stop being active. This limitation is not presented by intumescent products.
Frente al uso de productos intumescentes como protectores contra el fuego, en la presente invención se describe el uso de productos intumescentes en métodos activos para apagar el fuego.In the present invention, the use of intumescent products in active methods for extinguishing the fire is described in the present invention.
DESCRIPCIÓN DE LA INVENCIÓNDESCRIPTION OF THE INVENTION
El problema que se pretende solucionar con la presente invención es ampliar los posibles procedimien- tos activos para la extinción de fuegos.The problem that is intended to be solved with the present invention is to expand the possible active procedures for extinguishing fires.
En la presente invención se describe un procedimiento de extinción activo de incendios caracterizado porque dicha extinción de incendios se lleva a cabo mediante aplicación de un producto intumescente. - A -An active fire extinguishing process is described in the present invention characterized in that said fire extinguishing is carried out by application of an intumescent product. - TO -
En un segundo aspecto de la invención el producto intumescente se encuentra mezclado o dispersado en agua .In a second aspect of the invention the intumescent product is mixed or dispersed in water.
En un tercer aspecto de la invención la aplicación del producto intumescente se lleva a cabo mediante un soporte con estructura de malla cubierto con un producto intumescente que se arroja al fuego.In a third aspect of the invention the application of the intumescent product is carried out by means of a mesh structure support covered with an intumescent product that is thrown into the fire.
En un cuarto aspecto de la invención, la aplicación del producto intumescente se lleva a cabo mediante diversas formas de material expandible o no, cubiertas de producto intumescente que se arrojan al fuego.In a fourth aspect of the invention, the application of the intumescent product is carried out by various forms of expandable or non-expandable material, covered with intumescent product that are thrown into the fire.
Se entiende como producto intumescente aquel que por acción del calor se expande, es decir, aumenta su volumen al menos 20 veces su volumen.An intumescent product is understood as one that expands by the action of heat, that is, increases its volume by at least 20 times its volume.
Un ejemplo de producto intumescente es el cons- tituidos por, al menos cuatro ingredientes sinérgicos entre si:An example of an intumescent product is constituted by at least four synergistic ingredients:
• un agente catalizador tal como el polifosfato amónico, el cual a temperatura de unos 2000C liberará ácido polifosfórico, • un formador de carbón, tal como substancias orgánicas que reaccionan con el ácido polifosfórico, como el pentaeritrol o el dipentaeritrol,• a catalyst agent such as ammonium polyphosphate, which at temperatures of about 200 0 C release polyphosphoric acid, • charforming as organic substances that react with polyphosphoric acid, such as pentaerythritol or dipentaeritrol,
• un agente formador de gases inertes como la melani- na la cual producirá nitrógeno y amoniaco y expandirá la película,• an inert gas forming agent such as melanin which will produce nitrogen and ammonia and expand the film,
• agentes adhesivos como resinas acrilicas, epoxi, aminicas, siliconas.• adhesive agents such as acrylic, epoxy, aminic, silicon resins.
Si un producto intumescente incluye en su compo- sición grafito expandible, la expansión del volumen puede estar entre 150 y 350 veces.If an intumescent product includes expandable graphite in its composition, volume expansion It can be between 150 and 350 times.
La estructura del grafito está formada por láminas de anillos de carbono dispuestas paralelamente, entre laminas paralelas existe la distancia suficiente para la introducción de átomos o pequeñas moléculas. Si se introducen compuestos generadores de gases como sulfuro, nitrógeno o melamina, se consigue que el grafito se expanda con el calor. En función de la naturaleza del material, la expansión puede comenzar a temperaturas por debajo de los 1500C.The graphite structure is formed by sheets of carbon rings arranged in parallel, between parallel sheets there is enough distance for the introduction of atoms or small molecules. If gas-generating compounds such as sulfur, nitrogen or melamine are introduced, graphite expands with heat. Depending on the nature of the material, the expansion can begin at temperatures below 150 0 C.
Cuando en la presente memoria se refiere el termino grafito expandible se denota grafito al cual entre las láminas de anillos de carbono dispuestas paralelas se le ha introducido moléculas generadoras de gases que se expanden con el calor.When the term "expandable graphite" is referred to herein, graphite is denoted to which carbon-generating molecules that expand with heat have been introduced between the carbon ring sheets arranged parallel.
El grafito expandible puede presentarse en polvo o dispersión acuosa, de forma que se puede mezclar con el agua que vaya a ser utilizada en la extinción de un incendio.The expandable graphite can be presented in powder or aqueous dispersion, so that it can be mixed with the water to be used in extinguishing a fire.
Junto con estos productos intumescentes se pue- den utilizar coadjuvantes, materiales ceramificantes, nanomateriales, y materiales que contienen un porcentaje importante de agua de hidratación tales como trióxido de aluminio, e hidróxido de magnesio, y otros productos de reconocido efecto de resistencia al fuego como el óxido de antimonio, el borato de zinc o la mica.Together with these intumescent products, coadjuvants, ceramifying materials, nanomaterials, and materials containing a significant percentage of hydration water such as aluminum trioxide, and magnesium hydroxide, and other products of recognized fire resistance effect such as antimony oxide, zinc borate or mica.
Los materiales ceramificantes son capaces de formar una estructura compacta o semiporosa, que puede substituir a un polimero presente en el producto intu- mescente en la medida en que este desaparece por la combustión. Por otra parte, los gases de descomposición del polímero se aprovechan para formar una ligera intumescencia, que facilita el control del fuego.Ceramifying materials are capable of forming a compact or semi-porous structure, which can replace a polymer present in the intuitive product to the extent that it disappears by combustion. On the other hand, the decomposition gases of the polymer are used to form a slight intumescence, which facilitates the control of fire.
Los nanomateriales ayudan a mantener el aislamiento térmico de la intumescencia a temperaturas superiores a los 10000C; se evita con ello la formación de grietas, que perjudicarían el efecto aislante. Ejemplo de nanomateriales que pueden utilizarse son nanoarcillas y nanopartículas de sílice.The nanomaterials help to maintain the thermal insulation of the intumescence at temperatures above 1000 0 C; This prevents the formation of cracks, which would damage the insulating effect. Examples of nanomaterials that can be used are silica nano-clays and nanoparticles.
Cuando en la presente invención se refiere el término extinción activa denota que se ataca directamente sobre el incendio para sofocar la llama, en estos métodos se forma la intumescencia desplazando violentamente el aire próximo al combustible o se enfría el combustible .When the term active extinction refers to the present invention denotes that it is attacked directly on the fire to quench the flame, in these methods intumescence is formed by violently displacing the air next to the fuel or the fuel cools.
