El campo de aplicación de la invención se encuentra comprendido dentro del sector industrial dedicado a la fabricación de productos espumados, en particular productos obtenidos a base de espuma de látex.The scope of the invention is is included within the industrial sector dedicated to the manufacture of foamed products, in particular products obtained based on latex foam.

Antecedentes y sumario de la invenciónBackground and summary of the invention

Es conocido por todos en general el hecho de que un gran número de viviendas incluyen la instalación de parquet, bandas laminas, tarima flotante, o similar en los suelos. La utilización de estos materiales a base de madera, no sólo proporciona mejoras desde el punto de vista estético, sino que también es, en la práctica, fácil y rápido de instalar, admite ser reparado cuando se deteriora a causa de su uso continuado, y también proporciona un ambiente más cálido que con otros tipos de suelos.It is known to everyone in general the fact that a large number of homes include parquet installation, laminated bands, floating flooring, or similar on the floors. The use of these wood-based materials, not only provides improvements from the aesthetic point of view, but that It is also, in practice, easy and quick to install, admits to being repaired when it deteriorates due to its continued use, and it also provides a warmer environment than with other types of floors.

Sin embargo, frente a las ventajas obtenidas con la utilización de suelos de parquet, láminas de madera, tarima flotante o similares, como se ha mencionado brevemente en lo que antecede, la instalación de estos materiales no está exenta de otros inconvenientes. Por un lado, se debe tener presente la acumulación de agua que se produce en el suelo debido a los procesos de limpieza y/o a la humedad retenida bajo el suelo, lo que conduce con frecuencia al hinchamiento de la madera del parquet o similar y al desencajado de las diferentes piezas o láminas. Por otro lado, debe considerarse también el hecho de que el aislamiento logrado con su utilización no es tan bueno como sería deseable, dado que a través de la madera se produce una transmisión de las ondas acústicas que, transmitidas a las viviendas contiguas, dan lugar a molestias en estas últimas. Por último, existe también un fenómeno electrostático, más acusado en épocas en las que la temperatura ambiente es más elevada, derivado de la acumulación de electricidad en el material debido a su baja conductividad, que al final se traduce en indeseables descargas en los momentos más inesperados.However, compared to the advantages obtained with the use of parquet floors, wood sheets, flooring floating or similar, as mentioned briefly in what above, the installation of these materials is not exempt from other inconveniences On the one hand, the accumulation of water that occurs in the soil due to cleaning processes and / or moisture retained under the floor, which frequently leads to swelling of parquet wood or similar and to the disengagement of the different pieces or sheets. By on the other hand, the fact that the isolation achieved with its use is not as good as it would be desirable, since a transmission occurs through wood of the acoustic waves that, transmitted to adjacent homes,  They give rise to discomfort in the latter. Finally, there is also an electrostatic phenomenon, more pronounced in times when the ambient temperature is higher, derived from the accumulation of electricity in the material due to its low conductivity, which at final translates into undesirable downloads in the most moments Unexpected

Como consecuencia de todo ello, y con el fin de lograr un mejor comportamiento de este tipo de suelos y proporcionar a la vez una base de soporte para los mismos, se suelen utilizar materiales laminados que son posicionados bajo el parquet o similar, cuando se realiza la instalación de este último. Estos materiales laminados suelen consistir normalmente en láminas de espuma de polietileno expandido, láminas de materiales plásticos, espumas de látex, corcho aluminizado, caucho recuperado, poliuretano, etc. Cuando los materiales utilizados no presentan un aislamiento a la humedad adecuado, es necesario utilizar además algún tipo de aislamiento adicional, tal como una película de plástico o similar, que se sitúa bajo el material laminado en una operación separada. Todo ello conduce a la utilización de abundante mano de obra que indudablemente tiene una repercusión relevante en los gastos de construcción.As a result of all this, and in order to achieve better behavior of this type of soil and provide at the same time a support base for them, it they usually use laminated materials that are positioned under the parquet or similar, when the latter is installed. These laminated materials usually consist of sheets made of expanded polyethylene foam, material sheets plastics, latex foams, aluminized cork, reclaimed rubber, polyurethane, etc. When the materials used do not present a adequate moisture insulation, it is also necessary to use some additional insulation, such as a film of plastic or similar, which is placed under the laminated material in a separate operation All this leads to the use of abundant workforce that undoubtedly has a relevant impact on construction costs

Tomando en consideración la situación de la técnica actual, la presente invención se ha propuesto como objetivo principal el hecho de elaborar un producto que, teniendo las propiedades habituales de la espuma de látex y obtenido mediante un proceso de características similares a las que son habituales en la fabricación de este tipo de productos, permita obtener un material laminado que incorpore por sí mismo características de aislamiento sin necesidad de otros materiales adicionales, por incluir ya, por una de sus caras, una lámina de plástico íntimamente adherida al mismo que le proporciona el carácter de impermeabilidad al agua que se desea. Este objetivo ha sido plenamente alcanzado mediante la presente invención, según el procedimiento que se recoge en la parte caracterizadora de la reivindicación 1, el dispositivo que se define en la parte caracterizadora de la reivindicación 4 y el producto final y su utilización que se encuentran definidos en las reivindicaciones 5 a 7.Taking into account the situation of the current technique, the present invention has been proposed as an objective  principal the fact of elaborating a product that, having the usual properties of latex foam and obtained by a process of characteristics similar to those that are common in the manufacture of this type of products, allow to obtain a material laminate that incorporates insulation features on its own without the need of other additional materials, to include already, by one of its faces, a plastic sheet intimately adhered to the same that provides water impermeability that is desired. This objective has been fully achieved through the present invention, according to the procedure set out in the characterizing part of claim 1, the device that is defined in the characterizing part of claim 4 and the final product and its use that are defined in the claims 5 to 7.

En esencia, el procedimiento de la invención parte de un compuesto destinado a proporcionar la espuma de látex, debidamente preparado junto con la cantidad de aire que se estime necesaria para que el producto tenga, una vez secado, la densidad final que se desee, y al que se han añadido los aditivos necesarios para el tipo de aplicación prevista, cuyo compuesto se suministra sobre un film de plástico, siendo ambos transportados conjuntamente por una cinta de lona, al dispositivo de tratamiento donde se somete, según es convencional, a fases de tratamiento superficial por IR, vulcanización y secado a través de un horno apropiado, para obtener a la salida del horno el producto final deseado, compuesto por el material espumado la que se encuentra firmemente adherido el film de plástico. El producto final puede ser recogido en rollos hasta su posterior utilización.In essence, the process of the invention part of a compound intended to provide latex foam, properly prepared along with the amount of air estimated necessary for the product to have, once dried, the density final desired, and to which the necessary additives have been added for the type of intended application, whose compound is supplied on a plastic film, both being transported together by a canvas tape, to the treatment device where subject, as is conventional, to phases of surface treatment by IR, vulcanization and drying through an appropriate oven, to  obtain the desired final composite product at the exit of the oven by the foamed material which is firmly adhered to the plastic film The final product can be picked up in rolls until later use.

Breve descripción de los dibujosBrief description of the drawings

La invención ha previsto asimismo la incorporación de una lámina de dibujos a título ilustrativo y en ningún caso limitativo, a efectos de facilitar su comprensión, en los que:The invention has also provided the incorporation of a sheet of drawings for illustrative purposes and in no limiting case, in order to facilitate its understanding, in those who:

La Figura 1 (única) muestra una representación esquematizada de un dispositivo en el que se lleva a cabo la elaboración del producto aislante espumado propuesto por la invención.Figure 1 (unique) shows a representation schematized of a device in which the elaboration of the foam insulation product proposed by the invention.

Descripción de una forma de realización preferidaDescription of a preferred embodiment

Tal y como se ha indicado en lo que antecede, la descripción detallada de la invención va a ser llevada a cabo en lo que sigue haciendo referencia a los dibujos anexos, en cuya Figura única se muestra una representación que ilustra esquemáticamente un dispositivo destinado a la puesta en práctica del procedimiento preconizado.As indicated above, the detailed description of the invention will be carried out as far as which continues to refer to the attached drawings, in whose Figure only one representation is shown that schematically illustrates a device intended for the implementation of the procedure recommended.

Si se atiende a dicha representación, se puede apreciar que en la misma aparece una instalación en la que, según es habitual, se distingue un transportador 1 de lona o similar, extendida entre rodillos 2 extremos, en cuyo recorrido se enfrenta a un dispositivo 3 de infrarrojos (IR) y atraviesa por el interior de un horno 4 de características adecuadas. Por el extremo de entrada de la lona 1 se ha previsto la colocación de un dispositivo 5, que incorpora un medio de rasqueta o similar, mediante el que se uniformiza el espesor de la capa de compuesto de látex 6 que se vierte hacia el transportador.If you attend to such representation, you can appreciate that there is an installation in which, according to it is usual, a canvas conveyor 1 or the like is distinguished, extended between rollers 2 ends, in whose course it faces to an infrared (IR) device 3 and goes through the interior of an oven 4 of suitable characteristics. By the end of entrance of the canvas 1 is planned the placement of a device 5, which incorporates a scraper means or the like, by means of which standardizes the thickness of the layer of latex compound 6 that is pour into the conveyor.

De acuerdo con la invención, un film de plástico 7 procedente de un rollo 8 o similar, cuyo espesor está comprendido en la gama de alrededor de 20 - 30 micras, se dispone directamente sobre dicha lona transportadora 1, debidamente tensado con el fin de evitar la formación de arrugas, con la ayuda de un dispositivo tensor 12, de modo que el látex 6, al ser vertido hacia la lona transportadora, cae directamente sobre dicho film 7, siendo transportado sobre éste último a lo largo de todo el recorrido. Inicialmente, y tras ser homogeneizado en espesor por medio del dispositivo de rasqueta 5 hasta dejar una altura de compuesto predeterminada sobre el film 7, típicamente una altura del orden de 1 a 10 mm (según las necesidades de cada caso), se somete a un curado o secado superficial por medio del dispositivo 3 de IR, y a continuación atraviesa el horno 4 donde se realiza la vulcanización y secado final del producto, como es habitual. El producto final 9 que se obtiene a la salida del horno 4, consiste en el material espumado 6 que ha quedado íntimamente vinculado al film de plástico 7 durante las operaciones de vulcanización y secado en el interior del horno 4. Estas operaciones en el interior del horno se realizan a una temperatura que está comprendida en una gama del orden de 150 a 170ºC, pero no obstante, la integridad del film de plástico está garantizada dado que el espesor de compuesto espumante situado sobre dicho film, al ser de una conductividad térmica muy baja, impide que el film pueda llegar a alcanzar valores de temperatura que pudieran perjudicarle.According to the invention, a plastic film 7 from a roll 8 or similar, the thickness of which is comprised in the range of around 20-30 microns, it is directly available on said conveyor 1, duly tensioned in order to prevent the formation of wrinkles, with the help of a device tensioner 12, so that the latex 6, when poured into the canvas conveyor, falls directly onto said film 7, being transported on the latter along the entire route. Initially, and after being homogenized in thickness by means of scraper device 5 until a compound height is left predetermined on film 7, typically a height of the order of 1 to 10 mm (according to the needs of each case), is subjected to a surface curing or drying by means of IR device 3, and to then it goes through oven 4 where vulcanization is performed and final drying of the product, as usual. The final product 9 which is obtained at the exit of the oven 4, consists of the material Foamed 6 that has been intimately linked to the plastic film 7 during vulcanization and drying operations inside of the oven 4. These operations inside the oven are carried out at a temperature that is in a range of the order of 150 at 170 ° C, but nevertheless, the integrity of the plastic film is guaranteed given that the thickness of foaming compound located on said film, being of a very low thermal conductivity, prevents the film from reaching temperature values that could harm him.

Por último, según puede apreciarse en la Figura, a la salida del horno 4 se ha previsto la disposición de un dispositivo de arrollamiento para la formación de rollos 11 de producto acabado, tal y como es convencional en el estado actual de la técnica.Finally, as can be seen in the Figure, at the exit of the oven 4 the provision of a winding device for roll formation 11 of finished product, as is conventional in the current state of The technique.

Como se comprenderá, un producto acabado con las características del que propone la invención, permite que las operaciones de instalación y montaje puedan ser simplificadas, por incorporar ya el recubrimiento impermeabilizante (film de plástico) extendido a través de una de sus caras. Además, según se indicó al comienzo de la descripción, la posibilidad de seleccionar las características del producto final, permite también que se puedan fabricar productos con aplicaciones o utilidades específicas, en virtud de las cargas de aditivo que se incorporen en la composición inicial. En este sentido, se puede añadir, por ejemplo, un aditivo que presente un cierto comportamiento conductor para la descarga de la electricidad estática, o bien de tipo bactericida para evitar la creación de hongos o bacterias en el material, o incluir una carga a base de basalto con el fin de reforzar las propiedades de aislamiento térmico y de propagación de ondas electromagnéticas, o cualquier otro adecuado.As will be understood, a product finished with the characteristics of the one proposed by the invention, allows the installation and assembly operations can be simplified, by incorporate the waterproofing coating (plastic film) spread across one of their faces. In addition, as indicated to beginning of the description, the possibility of selecting the characteristics of the final product, also allows them to be manufacture products with specific applications or utilities, in under the additive fillers that are incorporated into the composition initial. In this sense, for example, an additive can be added to present a certain conductive behavior for downloading static electricity, or bactericidal type to avoid creation of fungi or bacteria in the material, or include a load based on basalt in order to reinforce the properties of thermal insulation and electromagnetic wave propagation, or Any other suitable.

El resultado final obtenido consiste, por lo tanto, en un producto laminado compuesto por una base espumada y un film de plástico íntimamente vinculado a una de sus caras. El producto resulta especialmente indicado para ser extendido sobre la superficie del suelo, con la base de espuma en posición superior, y apoyar el parquet, suelo laminado, tarima flotante o similar, directamente sobre dicha base.The final result obtained consists, therefore both, in a laminated product composed of a foamed base and a  plastic film intimately linked to one of its faces. He product is especially indicated to be spread on the floor surface, with the foam base in the upper position, and support the parquet, laminate flooring, floating flooring or similar, directly on that basis.
