La Fig. 2 es una visa esquemática que ilustra el proceso de fabricación del panel de la Fig. 1.Fig. 2 is a schematic visa illustrating the manufacturing process of the panel of Fig. 1.
En dichos dibujos puede verse la constitución y modo de fabricación de un tipo sándwich 1 según la presente invención, destinado a ser usado principalmente como aislante acústico y térmico, con propiedades o no ignífugas o electrostáticas, pero también, eventualmente, como conductor de la electricidad estática en suelos, paredes y techos.In these drawings you can see the constitution and manufacturing mode of a sandwich type 1 according to the present invention, intended to be used primarily as an insulator acoustic and thermal, with properties or non-flame retardant or electrostatics, but also, eventually, as a conductor of the static electricity in floors, walls and ceilings.
El panel tipo sándwich 1 de la invención se trata de un producto que se comercializara en rollos o en planchas, y está constituido, según se ve en la Fig. 1, por tres capas:The sandwich panel 1 of the invention is it is a product that will be marketed in rolls or in plates, and it is constituted, as seen in Fig. 1, by three layers:
- --
- Un soporte textil 2, tejido o no tejido;A textile support 2, woven or nonwoven;
- --
- Una capa intermedia de espuma de látex 3; yA intermediate layer of latex foam 3; Y
- --
- Una tercera capa a base de un film 4 de plástico o aluminio.A third layer based on a film 4 of plastic or aluminum.
La tercera capa de film 4 de plástico o aluminio, sobresale una franja 6 de unos centímetros por uno de los costados del rollo o de la plancha del panel 1, para facilitar que pueda solaparse al rollo o la plancha contigua o adyacente, una vez se instalan los paneles sándwich 1 uno al lado de otro, para impedir sin que existan juntas que puedan permitir el paso de la humedad entrambos.The third layer of plastic film 4 or aluminum, a strip 6 of a few centimeters stands out for one of the sides of the roll or plate 1 panel, to facilitate that can overlap the adjacent or adjacent roll or plate once sandwich panels 1 are installed next to each other, to prevent without there being boards that can allow the passage of humidity both.
Entre la espuma de látex 3 y la tercera capa 4 de plástico o aluminio se dispone un aditivo de un polvo termoplástico 5.Between the latex foam 3 and the third layer 4 a powder additive is made of plastic or aluminum thermoplastic 5.
La espuma de látex 3, por sus características físicas es siempre un buen aislante acústico, cuyas propiedades se verán mejoradas según la densidad en que se fabrique o el tipo de látex utilizado. Combinando ambas variables, se pueden obtener las características que requiera cada caso de instalación en particular.The latex foam 3, for its characteristics Physical is always a good acoustic insulator, whose properties are will be improved according to the density in which it is manufactured or the type of latex used. Combining both variables, you can get the features that each installation case requires in particular.
La capa intermedia de espuma de látex 3 es la que determinara la capacidad aislante o conductora del producto final. La espuma de látex 3 es por si misma un pésimo conductor de la electricidad, pero añadiéndole los aditivos se puede obtener un producto antiestático que evite, la acumulación de energía estática mediante su descarga continua a tierra.The intermediate layer of latex foam 3 is the that will determine the insulating or conductive capacity of the product final. The latex foam 3 is itself a lousy conductor of electricity, but by adding additives you can get a antistatic product to avoid, the accumulation of static energy by continuous discharge to ground.

Indeed, as already said, the biggest problem The latex foam 3 is its low abrasion resistance. With the Textile support 2 prevents any contact of the latex foam 3 with other exterior materials that may be aggressive to maintain its surface characteristics, closing a wrap protective
La última capa a base el film 4 otorga una buena característica de protección contra la humedad. Si se desea un panel tipo sándwich 1 que solamente sea aislante acústico, será suficiente con colocar un film de plástico 4 adherido a la superficie de la espuma 3 mediante material termoplástico. Si se desea un producto antiestático, se substituye el plástico del film 4 por aluminio, que a sus características de impermeabilización, añadirá la de ser una buena conductora de la electricidad.The last layer based on film 4 gives a good moisture protection feature. If a panel is desired sandwich type 1 that is only acoustic insulator, will be enough to place a plastic film 4 attached to the foam surface 3 by thermoplastic material. Whether you want an antistatic product, the plastic film is replaced 4 by aluminum, which to its waterproofing characteristics, will add that of being a good conductor of electricity.
En la Fig. 2 puede verse que el proceso de fabricación del panel tipo sándwich 1 de la invención consiste en añadir a la forma tradicional de fabricar espuma de látex 3 con un soporte textil 2, alimentado desde un rollo 7, la colocación durante el mismo proceso de un material termoplástico en polvo 5, alimentado desde una tolva 8, en la superficie de la espuma 3.In Fig. 2 it can be seen that the process of Manufacture of sandwich panel 1 of the invention consists of add to the traditional way of making latex foam 3 with a textile support 2, fed from a roll 7, placement during the same process of a thermoplastic powder material 5, fed from a hopper 8, on the surface of the foam 3.
La vulcanización de la espuma se efectúa en un horno 9, después de lo cual, y de una forma continua, el látex vulcanizado sobre el soporte textil 2 se dobla por presión mediante unos rodillos 11, con la interposición previa sobre esa superficie del film 4 de plástico o de aluminio, alimentado desde otro rollo 10.The vulcanization of the foam is carried out in a oven 9, after which, and in a continuous way, the latex vulcanized on textile support 2 is bent under pressure by rollers 11, with the previous interposition on that surface of plastic or aluminum film 4, fed from another roll 10.
Posteriormente, el producto obtenido, constitutivo del panel tipo sándwich 1 de la presente invención, es enfriado a la temperatura ambiente, con lo que obtiene una adhesión idónea del film 4 a la espuma de látex 3.Subsequently, the product obtained, constituting the sandwich panel 1 of the present invention, is cooled to room temperature, thereby obtaining adhesion suitable from film 4 to latex foam 3.
El proceso de colocar el aditivo 5 en polvo sobre la espuma de látex 3 antes de su secado y vulcanización, se llevara a cabo preferentemente mediante el proceso descrito en la memoria de la solicitud de patente Nº P200401819.The process of placing additive 5 powder on the latex foam 3 before drying and vulcanization, it preferably carried out by the process described in the patent application memory No. P200401819.
Una vez fuera del horno de vulcanización 9, el producto puede ser reactivado en caso de ser necesario mediante unos infrarrojos, consiguiendo el anclaje del film, plástico o aluminio, mediante la presión de rodillos.Once out of the vulcanization oven 9, the product can be reactivated if necessary by means of infrared, getting the anchor of the film, plastic or aluminum, by roller pressure.
El film 4 utilizado podrá ser varios centímetros mas ancho, por los dos lados, que el rollo de espuma de látex 3 con soporte textil 2, para determinar la citada franja lateral sobresaliente 6 (Fig. 1). El producto final será el propio rollo una vez hecho el pegado del film 4. Podrá ser el resultado de cortar el rollo en su parte intermedia, quedando dos "semirrollos", por una de sus laterales las tres capas 2, 3, 4 irán cortadas de forma que ninguna de las tres sobresalga y por el otro quedara una parte del film 4 libre para conseguir que no penetre la humedad al solapar otros rollos durante su utilización. También podrá cortarse en planchas según el futuro uso que se le vaya a dar.The film 4 used may be several centimeters wider, on both sides, than the latex foam roll 3 with textile support 2, to determine the said protruding lateral strip 6 (Fig. 1). The final product will be the roll itself once the film 4 has been glued. It may be the result of cutting the roll in its intermediate part, leaving two " half-rolls ", for one of its sides the three layers 2, 3, 4 will be cut so that none of the three protrudes and on the other a part of the film 4 is free to ensure that moisture does not penetrate when other rolls overlap during use. It can also be cut into plates according to the future use that will be given.
