De esta forma, la composición ignifuga obtenida, además, de tener la doble función de actuar como substancia protectora contra el fuego y como substancia de ataque contra el fuego, al tener una densidad próxima a 1 g/cm3 se facilita el trasiego de la misma, a la vez que el producto queda adherido a la materia a proteger, y, esencialmente, se optimiza su utilización por los medios, tanto aéreos como terrestres, antiincendios convencionales. In this way, the flame retardant composition obtained, in addition, from having the double function of acting as a protective substance against fire and as a substance of attack against fire, having a density close to 1 g / cm 3 facilitates the transfer of the same, at the same time that the product is adhered to the material to be protected, and, essentially, its use is optimized by means, both aerial and terrestrial, of conventional firefighting.
CAMPO DE APLICACIÓN. SCOPE.
En la presente memoria se describe una composición ignifuga, teniendo aplicación tanto como substancia protectora contra el fuego, a modo de cortafuegos evitando su propagación y como substancia de ataque directo al fuego para apagar el mismo. ANTECEDENTES DE LA INVENCIÓN. A fireproofing composition is described herein, having application both as a protective substance against fire, as a firewall preventing its propagation and as a substance of direct attack on fire to extinguish it. BACKGROUND OF THE INVENTION
Como ya se hacía referencia en la solicitud de Patente de Invención ES 2 310 498 del mismo titular que el presente expediente, a grandes rasgos, existen tres tipos de incendios: los que se producen en sólidos como la madera, papel, plástico, etc.; los causados por líquidos inflamables y los originados por la electricidad. As reference was already made in the invention patent application ES 2 310 498 of the same holder as the present file, broadly speaking, there are three types of fires: those that occur in solids such as wood, paper, plastic, etc. ; those caused by flammable liquids and those caused by electricity.
En función del tipo de incendio los medios de ataque varían, y, así, el agua es el medio utilizado en la lucha contra los incendios de tipo "A", esto es, por los incendios de sólidos, por la eficacia que tiene al enfriar el material. En la lucha contra los incendios de tipo "B", esto es, en los incendios de líquidos, se utiliza espuma compuesta por una mezcla de agua, bicarbonato de sodio y sulfato de aluminio en polvo. Asimismo, al agua de dicha composición se le añade productos retardantes. Así, en todos los casos se trataba de medios de lucha contra el fuego con objeto de atacar el mismo y no con un efecto protector previo, tal como ya se preveía mediante la composición reivindicada en la solicitud de Patente ES 2 310 498. Depending on the type of fire, the means of attack vary, and, thus, water is the means used in the fight against "A" type fires, that is, for solid fires, for the efficiency of cooling the material. In the fight against type "B" fires, that is, in liquid fires, foam consisting of a mixture of water, sodium bicarbonate and powdered aluminum sulfate is used. Likewise, retardant products are added to the water of said composition. Thus, in all cases it was a means of fire fighting in order to attack it and not with a previous protective effect, as was already foreseen by the composition claimed in the patent application ES 2 310 498.
Siguiendo con lo que en su día ya se indicaba en la citada Patente ES 2 310 498 los incendios forestales, son un grave problema tanto por la pérdida de masa forestal y las consecuencias que ello acarrea, como por la posible pérdida de vidas humanas que, por desgracia, se suelen producir. Following what was already indicated in the aforementioned Patent ES 2 310 498 forest fires, are a serious problem both for the loss of forest mass and the consequences that this entails, as for the possible loss of human lives that, Unfortunately, they usually occur.
Así, la lucha contra los incendios forestales presenta diferentes problemas, de forma que dada su virulencia en su avance arrasan con todo lo que encuentran a su paso y las brigadas antiincendios no pueden aproximarse dada las altas temperaturas que se producen, por lo que, en primer lugar deben de utilizarse otros medios de ataque, tales como los aéreos. De esta forma, se lucha contra las llamas con medios aéreos vertiendo cantidades de agua contra las llamas para una vez reducido el fuego que las brigadas puedan aproximarse al mismo. Thus, the fight against forest fires presents different problems, so that given their virulence in their progress they destroy everything they find in their path and the fire brigades cannot approach due to the high temperatures that occur, so, in First, other means of attack, such as aerial ones, must be used. In this way, the flames are fought with aerial means by pouring quantities of water against the flames to reduce the fire that the brigades can approach.
Por otra parte, la eficacia de la lucha aérea se ve reducida dado que, como consecuencia de las altas temperaturas, el agua se evapora y la cantidad que llega es mínima y aunque, en un principio, se reduzca la fuerza del fuego por la pérdida de oxigeno, con frecuencia el mismo se reactiva. On the other hand, the effectiveness of the aerial fight is reduced since, as a consequence of the high temperatures, the water evaporates and the amount that arrives is minimal and although, in the beginning, the fire force is reduced by the loss of oxygen, often it reactivates.
Asimismo, en la lucha contra los incendios forestales se utilizan "corta fuegos" con objeto de impedir el avance del mismo una vez que llegan a ellos, pero, para que estos "corta fuegos" sean eficaces el terreno debe de estar totalmente limpio de maleza, lo que por desgracia, no suele ocurrir. Also, in the fight against forest fires "fires" are used in order to prevent the progress of the same once they reach them, but, for these "fires" to be effective, the land must be completely clean of weeds. , which unfortunately does not usually happen.
Asimismo, podemos indicar que la composición descrita en la Patente de Invención ES 2 310 498 presenta el inconveniente de que, dada su alta densidad de 1 ,62 g/cm3, la capacidad de transporte con los medios aéreos convencionales se reduce de forma considerable, viéndose afectada su optimización, en tanto que en el uso de los vehículos contraincendios convencionales, además, el trasiego de la composición presenta, por su alta densidad, inconvenientes en el paso de válvulas y en su circulación por las mangueras, afectando de forma seria a su posible viabilidad. Likewise, we can indicate that the composition described in the Invention Patent ES 2 310 498 has the disadvantage that, given its high density of 1.62 g / cm 3 , the transport capacity with conventional air means is reduced considerably, its optimization being affected, while in the use of conventional fire vehicles, in addition, the transfer of the composition presents, due to its high density, inconveniences in the passage of valves and their circulation through the hoses, seriously affecting their possible viability.
Así, además, de los documentos de patente ES 2123464; ES 2128315 y ES 2171187, ya citados en la solicitud de Patente de Invención ES 2310498, haciendo referencia a esta última podemos indicar que, tal como ya hemos indicado, se presentan una serie de inconvenientes, derivados de su alta densidad que, en la práctica, reducen su viabilidad. Thus, in addition, of patent documents ES 2123464; ES 2128315 and ES 2171187, already cited in the invention patent application ES 2310498, referring to the latter we can indicate that, as we have already indicated, there are a number of drawbacks, derived from its high density which, in practice , reduce its viability.
Haciendo hincapié en dichos documentos, brevemente, podemos indicar que en el documento ES 2123464 se describe una composición adecuada para producir una espuma contra incendios, espuma y sistema de prevención y extinción de incendios que utiliza dicha espuma, cuya composición comprende un tensioactivo aniónico y un agente estabilizador de la espuma. Emphasizing these documents, briefly, we can indicate that in document ES 2123464 a composition suitable for producing a fire foam, foam and fire prevention and extinguishing system using said foam is described, the composition of which comprises an anionic surfactant and a foam stabilizing agent.
En el documento ES 2128315 se describe una composición para la extinción de incendios, cuya composición comprende, al menos, un propano fluorosustituido y un método para evitar incendios a base de establecer en un espacio cerrado una atmósfera con contenido de oxigeno pero que no sustenta la combustión, basado en la introducción en el espacio cerrado de, al menos, un propano fluorosustituido. In document ES 2128315 a fire extinguishing composition is described, the composition of which comprises at least one fluorosubstituted propane and a method to prevent fires based on establishing in an enclosed space an atmosphere containing oxygen but not supporting the combustion, based on the introduction into the closed space of at least one fluorosubstituted propane.
En el documento ES 21717187 se describe unas composiciones de cemento que contienen yeso y materiales fabricados a partir de las misma, cuya composición comprende entre un 30 y un 75% en peso de sulfato cálcico; entre un 10 y un 40% en peso de cemento Portland; entre un 4 y un 20% en peso de sílice de humo y entre un 1 y un 40% en peso de carga puzolánica. DESCRIPCIÓN DE LA INVENCIÓN. Document ES 21717187 describes cement compositions containing gypsum and materials made therefrom, the composition of which comprises between 30 and 75% by weight of calcium sulfate; between 10 and 40% by weight of Portland cement; between 4 and 20% by weight of silica fume and between 1 and 40% by weight of pozzolanic charge. DESCRIPTION OF THE INVENTION
En la presente memoria se describe una composición ignifuga, cuya composición comprende: COMPONENTE CANTIDAD A fire retardant composition is described herein, the composition of which comprises: COMPONENT QUANTITY

Entendiendo por micro esferas de vidrio esferas de vidrio con una granulometría comprendida entre 125 y 850 mieras. Silica sand 6.20-10.30% by weight and because it has a density of 1.042 to 1.082 g / cm 3 at room temperature above 5 ° C, so that compared to the composition object of the document ES 2 310 498, which has a density of 1.62 g / cm 3 (1.620 Kg / m 3 ), facilitates its transfer by conventional fire-fighting means, such as in fire-fighting vehicles circulating through the hoses and passing through the valves, and, in addition, in their use by the fire fighting air means, their application is optimized by being able to transport many more liters, evaluable by more than 50%. Understanding micro glass spheres glass spheres with a particle size between 125 and 850 microns.
Asimismo, la composición obtenida, igualmente, al ser aplicada queda adherida a la materia a proteger, teniendo dicha importante característica a pesar de su reducida densidad. Likewise, the composition obtained, also, when applied is adhered to the material to be protected, having said important characteristic despite its reduced density.
Así, siendo, normalmente, la capacidad de transporte de los medios aéreos de 3.000 kilos (3.000 litros de agua), con la composición objeto del documento ES 2 310 498 solo se podrán transportar unos 1.850 litros, quedando el depósito más de 1/3 vacío, pudiendo ser ello un inconveniente por el desplazamiento ("oleaje") que puede sufrir durante el transporte del producto, aún disponiendo de los medios convencionales en evitación de ello. Thus, being normally the transport capacity of the air means of 3,000 kilos (3,000 liters of water), with the composition object of document ES 2 310 498 only about 1,850 liters can be transported, leaving the tank more than 1/3 empty, this could be an inconvenience due to the displacement ("swell") that it may suffer during the transport of the product, even having the conventional means to avoid it.
Con la nueva composición y considerando una densidad de 1 ,06 g/cm3, la capacidad a transportar podrá ser de unos 2.800 litros, quedando claro la importante ventaja derivada de reducir la densidad de la composición. Asimismo, al quedar el depósito, prácticamente lleno, no se produce "oleaje" y se tiene una mayor seguridad en el transporte. Además, la nueva composición, una vez aplicada en la zona a proteger, permanece latente un mayor tiempo, hasta dos meses, ya que, queda adherida de tal manera que no es arrastra por vientos normales ni por pequeñas lluvias. With the new composition and considering a density of 1, 06 g / cm 3 , the capacity to be transported can be about 2,800 liters, making clear the important advantage derived from reducing the density of the composition. Also, when the tank is almost full, there is no "swell" and there is greater security in transport. In addition, the new composition, once applied in the area to be protected, remains latent for a longer period of time, up to two months, since it is adhered in such a way that it is not dragged by normal winds or by small rains.

Esta utilización como substancia protectora aporta una gran ventaja, ya que, con tiempo suficiente permite aplicarla sobre la superficie a proteger adhiriéndose a ella y creando una barrera corta fuegos, y con la gran ventaja añadida de permanecer latente con sus propiedades intactas por un periodo de, al menos, dos meses. This use as a protective substance provides a great advantage, since, with sufficient time, it can be applied on the surface to be protected by adhering to it and creating a fire barrier, and with the great added advantage of remaining dormant with its intact properties for a period of At least two months.
En la utilización de la composición ignifuga como substancia contra el fuego, la misma será aplicada sobre el fuego quedando adherida al material o vegetal que se estaba quemando y, posteriormente, al rociarla con agua la substancia protectora se desprende y es arrastrada por el agua. Otra importante ventaja es que la composición ignifuga es total y absolutamente ecológica y transpirable por lo que su aplicación sobre los vegetales no afecta a estos y, además, con el rociado con agua es eliminada totalmente, no viéndose afectados los vegetales. Además, con objeto de poder determinar, principalmente en aquellos casos en los que la composición ignifuga es utilizada como substancia protectora contra el fuego, la superficie en la que está presente o no, o con objeto de adecuarla a la estética del entorno en la que es aplicada, a la composición ignifuga se podrá incorporar, al menso, una substancia colorante, pudiendo estar presentes en un porcentaje entre el 0,1 y el 4%, viéndose disminuido el porcentaje del talco de la composición en el mismo porcentaje. In the use of the fireproofing composition as a substance against fire, it will be applied to the fire, adhering to the material or plant that was being burned and, subsequently, when sprayed with water, the protective substance is released and carried away by water. Another important advantage is that the fire retardant composition is totally and absolutely ecological and breathable so that its application on vegetables does not affect these and, in addition, with water spray is completely eliminated, the vegetables not being affected. In addition, in order to be able to determine, mainly in those cases in which the fire retardant composition is used as a protective substance against fire, the surface on which it is present or not, or in order to adapt it to the aesthetics of the environment in which it is applied, a coloring substance may be incorporated into the flame retardant composition, being able to be present in a percentage between 0.1 and 4%, the percentage of the talc of the composition being decreased by the same percentage.
En una variante de ejecución práctica de la invención las substancias colorantes estarán presentes en un porcentaje del 2% y, en dicho caso, el porcentaje de talco de la composición ignifuga será del 35,82%, es decir, el porcentaje del talco se ha visto reducido en el porcentaje de incorporación de las substancias colorantes.. In a practical embodiment variant of the invention, the coloring substances will be present in a percentage of 2% and, in that case, the talcum percentage of the flame retardant composition will be 35.82%, that is, the percentage of the talcum powder has been seen reduced in the percentage of incorporation of the coloring substances ..
Asimismo, la composición ignifuga objeto de la invención puede incorporar substancias fluorescentes o fosforescentes mediante las cuales se podrá determinar en qué zonas, de las que previamente ha sido aplicada la composición como substancia protectora contra el fuego, está presente todavía. Likewise, the flame retardant composition object of the invention can incorporate fluorescent or phosphorescent substances by means of which it can be determined in which areas, from which the composition has been previously applied as a protective substance against fire, is still present.
Así, por ejemplo, en caso de lluvia sobre la superficie en la que se ha aplicado la composición ignifuga como substancia protectora contra el fuego, se podrá determinar en que zonas la lluvia ha arrastrado la composición o no, con objeto de poder volver a aplicar la composición en las zonas de peligro de propagación del fuego, en caso de existir riesgo todavía. Thus, for example, in case of rain on the surface on which the fire retardant composition has been applied as a protective substance against fire, it can be determined in which areas the rain has dragged the composition or not, in order to be able to reapply the composition in the areas of danger of fire propagation, if there is still a risk.
De esta forma, la composición ignifuga objeto de la invención es de especial aplicación en la lucha y protección de los incendios forestales, permitiendo la creación de barreras protectoras, así como la protección de zonas determinadas, como pueden ser zonas habitadas respecto de las que, perimetralmente, se pueden crear auténticas barreras de protección. In this way, the fire retardant composition object of the invention is of special application in the fight and protection of forest fires, allowing the creation of protective barriers, as well as the protection of certain areas, such as inhabited areas with respect to which, perimeter, authentic protection barriers can be created.
EJEMPLO.- Se preparo una composición ignifuga de 1.000 Kg. en base a los siguientes porcentaj una temperatura ambiente de 15°C: EXAMPLE.- A 1,000 kg fireproof composition was prepared based on the following percentages at an ambient temperature of 15 ° C:
Figure imgf000010_0001
presentando la composición una densidad de 1 ,06 g/cm3, de forma que el conservante puede tratarse de isotiazolonas.
Figure imgf000010_0001
the composition having a density of 1.06 g / cm 3 , so that the preservative can be isothiazolones.
Un vez determinada esta composición, 300 Kg. se aplicaron como substancia protectora, parcialmente, sobre una masa vegetal constituida por ramas secas de olivo, a las que quedo adherida sin escurrirse, dejando una parte lateral sin la aplicación de la composición y se prendió fuego por la zona sin proteger, de manera que las ramas sin proteger ardieron con gran rapidez y virulencia y al llegar a la zona o superficie protegida las llamas dejaron de avanzar hasta extinguirse. Por otra parte, otros 300 Kg. se aplicaron como substancia contra el fuego, de manera que previamente se había preparado una masa vegetal constituida por ramas secas de olivo a las que se les prendió fuego, de manera que las ramas ardían con gran rapidez y virulencia pero al aplicar la composición el fuego se apago. Posteriormente, tanto en un caso como en el otro, al verter agua sobre la masa restante la composición fue arrastrada por el agua y las ramas protegidas quedaron a la vista nuevamente. Once this composition was determined, 300 Kg. Were applied as a protective substance, partially, on a vegetal mass constituted by dried olive branches, to which it remained adhered without draining, leaving a lateral part without the application of the composition and fire was set on. through the unprotected area, so that the unprotected branches burned very quickly and virulence and when they reached the protected area or surface the flames stopped advancing until they died out. On the other hand, another 300 Kg. Were applied as a substance against fire, so that previously a vegetable mass consisting of dried olive branches had been prepared to which they were set on fire, so that the branches burned very quickly and virulence but when applying the composition the fire went out. Subsequently, both in one case and in the other, by pouring water on the remaining mass the composition was dragged by the water and the protected branches were visible again.
Asimismo, a 200 Kg. de la composición inicial obtenida se le añadieron 4 Kg. de substancias colorantes verdes y fueron aplicados sobre una masa forestal arbolada quedando perfectamente integrada en el entorno, permaneciendo inalterable durante treinta días, tras los cuales al aplicar agua la composición fue arrastrada y la masa forestal arbolada permanecías en perfecto estado. Finalmente, al resto de los 200 Kg. de la composición inicial obtenida se le incorporaron substancias fluorescentes y fue aplicada sobre una masa forestal arbolada pudiendo observar las zonas en las que la misma fue aplicada y como con el transcurrir de los días permanecía, hasta que al cabo de veinticinco días fue arrastrada y eliminada por la lluvia, permaneciendo la masa forestal arbolada en perfecto estado. Likewise, to 200 Kg. Of the initial composition obtained, 4 Kg. Of green coloring substances were added and applied on a wooded forest mass being perfectly integrated in the environment, remaining unchanged for thirty days, after which when applying the water the composition It was dragged and the wooded forest mass remained in perfect condition. Finally, to the rest of the 200 Kg. Of the initial composition obtained fluorescent substances were incorporated and it was applied on a wooded forest mass being able to observe the areas in which it was applied and as with the passing of the days it remained, until After twenty-five days it was dragged and eliminated by the rain, with the wooded forest mass in perfect condition.
EJEMPLO.- Se preparo una composición ignifuga de 1.000 Kg. en base a los siguientes porcentajes y a una temperatura ambiente de 18°C: EXAMPLE.- A fireproof composition of 1,000 kg was prepared based on the following percentages and at an ambient temperature of 18 ° C:
