Description
Uso de una resina para la obtención de paneles de construcción.Use of a resin to obtain panels building.
La presente invención se refiere al uso de una resina en la obtención de paneles de construcción mediante su aplicación sobre un panel de poliestireno expandido al objeto de obtener una capa resistente que permite el empleo del panel en la construcción, constituyendo muros de carga, tabiquería, paredes, falsos techos u otros.The present invention relates to the use of a resin in obtaining construction panels by means of its application on an expanded polystyrene panel for the purpose of obtain a resistant layer that allows the use of the panel in the construction, constituting load-bearing walls, partition walls, walls, false ceilings or others.
La resina puede ir acompañada de cargas, con el objeto de reducir la cantidad de resina utilizada, reducir el coste de obtención del panel y proporcionar un acabado exterior del mismo similar a la de un muro obtenido por monocapa.The resin can be accompanied by charges, with the in order to reduce the amount of resin used, reduce the cost to obtain the panel and provide an exterior finish thereof similar to that of a wall obtained by monolayer.
Los paneles de poliestireno expandido se emplean de forma generalizada en la industria de la construcción, aplicándose sobre las paredes o muros con fines aislantes, principalmente como aislante térmico como acústico, pero siempre adosados o fijados a la pared o muro resistente ya que su fragilidad impide utilizarlos directamente como elementos de tabiquería.Expanded polystyrene panels are used in general in the construction industry, applying on walls or walls for insulating purposes, mainly as thermal insulator as acoustic, but always attached or fixed to the wall or resistant wall since its fragility prevents using them directly as partitions.
Por otra parte, las resinas se emplean en distintas aplicaciones entre las que cabe destacar su utilización como elementos de cohesión en materiales compuestos para establecer la vinculación entre plásticos y fibras de refuerzo pero, hasta el momento no se han aplicado sobre paneles o láminas de poliestireno expandido, para su empleo como elementos constructivos.On the other hand, resins are used in different applications among which its use should be highlighted as cohesion elements in composite materials to establish the bond between plastics and reinforcing fibers but, until the At the moment they have not been applied on polystyrene panels or sheets expanded, for use as constructive elements.
La presente invención propone el uso de una resina en la obtención de paneles para la construcción mediante la aplicación de la resina sobre una lámina de poliestireno expandido, de tal manera que la resina confiere al panel una resistencia suficiente que permite su empleo como elemento constructivo, sin necesidad de utilizar elementos de refuerzo o soporte, manteniendo e incluso mejorando las características del poliestireno en cuanto a resistencia al fuego y aislamiento térmico y acústico.The present invention proposes the use of a resin in obtaining panels for construction by means of application of the resin on an expanded polystyrene sheet, in such a way that the resin gives the panel a resistance sufficient that allows its use as a constructive element, without need to use reinforcement or support elements, maintaining e even improving the characteristics of polystyrene in terms of fire resistance and thermal and acoustic insulation.
El panel obtenido está compuesto por tanto por un núcleo o alma de poliestireno expandido y una capa exterior resistente, de resina, de tal manera que el panel presenta una gran ligereza y manejabilidad, como consecuencia del reducido peso del núcleo de poliestireno y unas características resistentes, conferidas por la resina aplicada, que permite su utilización para la obtención de tabiques, muros de carga, falsos techos y, en general, como elementos de construcción.The panel obtained is therefore composed of a core or core of expanded polystyrene and an outer layer resistant, of resin, in such a way that the panel presents a great lightness and manageability, as a result of the reduced weight of the polystyrene core and tough features, conferred by the applied resin, which allows its use for obtaining partitions, load-bearing walls, false ceilings and, in general, as building elements.
La resina empleada se selecciona dentro del grupo compuesto por poliisobutadienos, poliésteres, poliamidas cicloalifáticas, epoxis, resinas fenólicas o poliuretanos.The resin used is selected within the group composed of polyisobutadienes, polyesters, polyamides cycloaliphatics, epoxies, phenolic resins or polyurethanes.
La utilización de un tipo u otro de resina estará determinada por el uso que se pretenda dar al panel, en cualquier caso se obtendrá una resistencia suficiente para la utilización del panel como muro exterior, muro de carga en construcciones, tabiquería, falsos techos, suelos mullos pantallas y otros.The use of one type or another of resin will be determined by the intended use of the panel, in any In this case, sufficient resistance will be obtained for the use of the panel as exterior wall, load wall in constructions, partition walls, suspended ceilings, floor screens and other mullos.
La resina en cuestión se mezcla normalmente con un catalizador para acelerar el proceso de curado de la misma sobre la lámina de poliestireno expandido, en una relación aproximada de dos partes de resina por cada parte de catalizador, aunque esta proporción puede variar en función de la temperatura ambiente, siendo necesaria en ocasiones la inclusión de aditivos que aceleren la catalización.The resin in question is normally mixed with a catalyst to accelerate the curing process thereof over the expanded polystyrene sheet, in an approximate ratio of two parts of resin for each part of catalyst, although this proportion may vary depending on the ambient temperature, being sometimes necessary the inclusion of additives that accelerate Catalyzing
La capa resistente incorpora, además de la resina, una serie de cargas, como por ejemplo arena de sílice, corindón, vidrio triturado, carburo de silicio etc., con el fin de reducir la cantidad de resina utilizada, reduciéndose así el coste de obtención de los paneles.The resistant layer incorporates, in addition to the resin, a series of charges, such as silica sand, corundum, crushed glass, silicon carbide etc., in order to reduce the amount of resin used, thus reducing the cost of obtaining the panels.
Esta capa resistente presenta un espesor entre 2 y 10 mm. pero, ajustando debidamente la cantidad de cargas utilizadas y de resina se pueden conseguir unas características óptimas con una capa resistente entre 2 y 4 mm.This resistant layer has a thickness between 2 and 10 mm. but, properly adjusting the amount of charges used and resin characteristics can be achieved optimal with a resistant layer between 2 and 4 mm.
Además, en caso de utilizar arenas, se consigue un acabado del panel similar al de una fachada obtenida mediante las técnicas monocapa tradicionales. La arena tiene también una importante resistencia al fuego.In addition, in case of using sands, you get a panel finish similar to that of a facade obtained by traditional monolayer techniques. The sand also has a Important fire resistance.
El núcleo del panel sobre el que se aplica la resina es una lámina de poliestireno expandido, cuya densidad varía entre 10 Kg/m^{3} y 40 Kg/m^{3}. Obviamente, cuanto mayor densidad presente el poliestireno, mejores características tendrá el panel pero, también su precio será mas elevado.The core of the panel on which the resin is an expanded polystyrene sheet, whose density varies between 10 Kg / m 3 and 40 Kg / m 3. Obviously, the older density present polystyrene, better features will have the panel but, also its price will be higher.
En cualquier caso, se puede conseguir unas óptimas características de resistencia, utilizando poliestireno expandido de 20 kg/m^{3} de densidad, consiguiendo así también una óptima relación calidad precio para los paneles.In any case, you can get some optimal resistance characteristics, using polystyrene expanded by 20 kg / m3 density, thus also achieving a Optimum price-quality ratio for the panels.
Asimismo, el núcleo del panel puede estar compuesto también por poliestireno extrusionado o incluso poliuretano, en sus diversas densidades.Also, the core of the panel may be also composed of extruded polystyrene or even polyurethane, in its various densities.
El proceso de obtención de la capa resistente sería el siguiente:The process of obtaining the resistant layer It would be the following:
- --
- Se vierte sobre la lámina de poliestireno la resina junto con el catalizador y se extiende adecuadamente.Be pour the resin along with the polystyrene sheet catalyst and extends properly.
- --
- Se aplican las cargas sobre la capa de resina distribuyéndolas uniformemente.Be apply the loads on the resin layer distributing them evenly.
- --
- Se deja curar la resina y se vuelve a aplicar una segunda capa de resina y carga.Be let the resin cure and reapply a second layer of resin and load.
La aplicación de la segunda capa, es opcional y permite que el panel adquiera una mayor cantidad de arena y además con la segunda capa se consigue un aspecto exterior mas uniforme.The application of the second layer is optional and allows the panel to acquire a greater amount of sand and also with the second layer you get a more external appearance uniform.
En concreto, para una lámina de poliestireno de 500 mm. de ancho por 2000/2500 mm. de largo, se utilizan aproximadamente 1,5 litros de resina, concretamente medio litro para la primera capa y un litro para la segunda.Specifically, for a polystyrene sheet of 500 mm wide by 2000/2500 mm. long, they are used approximately 1.5 liters of resin, specifically half a liter for the first layer and a liter for the second.
Una vez que el panel se ha secado completamente se puede aplicar una pintura plástica u otro elemento de acabado superficial, por ejemplo, por proyección de polvos de revestimiento.Once the panel has dried completely a plastic paint or other finishing element can be applied surface, for example, by spraying powders of coating.
El panel puede utilizarse de modo individual o bien puede combinarse con otros paneles a los que se adhiere por medio de la propia resina, que no sólo es empleada como medio de refuerzo sino como medio adhesivo, hasta formar un módulo tipo sándwich conformado por dos, tres o mas paneles, de acuerdo con el uso que se le quiera dar.The panel can be used individually or It may well be combined with other panels to which it adheres by medium of the resin itself, which is not only used as a means of reinforcement but as an adhesive medium, to form a module type sandwich consisting of two, three or more panels, according to the use that you want to give.
Los paneles pueden presentar acabados de imitación que se dibujan en el poliestireno, previamente a la aplicación de la resina, consiguiendo así acabados que imitan piedra, ladrillo, granito, mármol, etc.The panels can present finishes of imitation that are drawn in polystyrene, prior to resin application, thus obtaining finishes that mimic stone, brick, granite, marble, etc.
