Description

DESCRIPCIÓNDESCRIPTION

BLOQUE RECICLADO ACÚSTICO E IGNÍFUGOACOUSTIC AND FIREPROOF RECYCLED BLOCK

SECTOR DE LA TÉCNICATECHNIQUE SECTOR

La presente invención consiste en un bloque muy ligero de material reciclado destinado a ser utilizado en el sector de la construcción, acústica, protección contra el fuego y automoción como elemento de recubrimiento o barrera acústica e ignífuga, el cual está realizado a partir de restos de espuma de melamina.The present invention consists of a very light block of recycled material intended to be used in the construction, acoustic, fire protection and automotive sectors as a covering element or acoustic and fireproof barrier, which is made from remains of melamine foam.

ANTECEDENTES DE LA INVENCIÓNBACKGROUND OF THE INVENTION

Actualmente, son conocidos diversos tipos de paneles para la construcción y otros sectores del mercado realizados con desperdicios que se producen al cortar grandes bloques de espuma de poliuretano en cojines, colchones y similares. Estos recortes son aglomerados por medio de un aglutinante a partir de isocianato y, por lo menos, un aditivo hidrófobo.Various types of panels for construction and other market sectors made with waste produced by cutting large blocks of polyurethane foam into cushions, mattresses and the like are currently known. These scraps are agglomerated by means of an isocyanate-based binder and at least one hydrophobic additive.

Las espumas de poliuretano tienen una densidad que va desde 30 kg/m3 hasta más de 400 kg/m3 y, para su reciclado, los recortes de espuma se desmenuzan en copos de espuma que se comprimen y aglomeran unos con otros por medio de un aglomerante.Polyurethane foams have a density ranging from 30 kg/m3 to more than 400 kg/m3 and, for recycling, the foam scraps are shredded into foam flakes that are compressed and agglomerated with each other by means of a binder. .

La espuma aglomerada resultante, debido a la compresión efectuada durante su aglomeración, tiene una densidad mayor que la espuma de la que se produce, por lo que el producto reciclado se utiliza en diferentes campos a los de la espuma original. Así pues, el producto reciclado a partir de espuma de poliuretano tiene unas bajas prestaciones como material acústico e ignífugo.The resulting agglomerated foam, due to the compression carried out during its agglomeration, has a higher density than the foam from which it is produced, for which reason the recycled product is used in different fields from those of the original foam. Thus, the product recycled from polyurethane foam has low performance as an acoustic and fireproof material.

Ejemplos de dichos materiales se describen en los documentos BE9900082W, EP05108337A, BE9301273A o US201715637723A.Examples of such materials are described in the documents BE9900082W, EP05108337A, BE9301273A or US201715637723A.

Por consiguiente, sería beneficioso el desarrollo de un bloque de material reciclado acústico e ignífugo, con unas prestaciones equivalentes o superiores a las de los recubrimientos de aglomerado de espuma de poliuretano. Consequently, it would be beneficial to develop a block of acoustic and fireproof recycled material, with performance equivalent to or better than that of polyurethane foam agglomerate coatings.

EXPLICACIÓN DE LA INVENCIÓNEXPLANATION OF THE INVENTION

La presente invención da solución al problema objetivo planteado al constituir un bloque de material aglomerado realizado con los restos sobrantes de procesos productivos variados, principalmente de espuma de melamina, que presenta una densidad final de entre un 18 a 32 Kg/m3, y que posee una gran capacidad de absorción acústica, así como una alta resistencia a largo plazo a altas temperaturas sin la necesidad de usar retardantes de fuego. Este tipo de espuma, a diferencia de las espumas de poliuretano, no arde ni funde en contacto con el fuego.The present invention provides a solution to the objective problem posed by constituting a block of agglomerate material made with the remains left over from various production processes, mainly melamine foam, which has a final density of between 18 to 32 Kg/m3, and which has a great acoustic absorption capacity, as well as a high long-term resistance to high temperatures without the need to use fire retardants. This type of foam, unlike polyurethane foams, does not burn or melt in contact with fire.

Para ello, el nuevo bloque está realizado como aglomerado de recortes de una espuma termoestable de célula abierta microporosa y estructura en red tridimensional de hebras más duras comparativamente a las burbujas separadas de la espuma de poliuretano, principalmente espuma de melamina, procedente de recortes industriales que han sido reducidos a copos de volumen homogéneo y aglomerados con resina de poliuretano a base de poliol e isocianatos en un molde donde se someten a una compresión por fases que garantiza una densidad homogénea en todo el bloque. To do this, the new block is made as an agglomerate of scraps of microporous open-cell thermosetting foam with a three-dimensional network structure of harder strands compared to the separate bubbles of polyurethane foam, mainly melamine foam, from industrial scraps that They have been reduced to flakes with a homogeneous volume and agglomerated with polyol and isocyanate-based polyurethane resin in a mold where they are subjected to phased compression that guarantees a homogeneous density throughout the block.

Los bloques según la invención, al realizarse con copos de espuma termoestable de célula abierta microporosa, en caso de incendio no se derriten ni producen gotas ardientes cuando entran en contacto con las llamas, simplemente se carbonizan y producen una pequeña cantidad de humo sin resplandor posterior, lo que los hace particularmente adecuados para aplicaciones con altos requisitos de seguridad contra incendios.The blocks according to the invention, being made of microporous open cell thermosetting foam flakes, in the event of a fire do not melt or produce burning droplets when in contact with the flames, they simply char and produce a small amount of smoke without afterglow , which makes them particularly suitable for applications with high fire safety requirements.

Al mismo tiempo, la superficie de célula abierta microporosa impide que las ondas acústicas se reflejen como un eco, ya que estas penetran sin problemas en la estructura de la célula reduciendo la energía del sonido.At the same time, the microporous open cell surface prevents acoustic waves from being reflected back as an echo, as they seamlessly penetrate the cell structure reducing sound energy.

Estas prestaciones son superiores o equiparables a las conseguidas con paneles acústicos y antitérmicos de lana viscoelástica, geotextiles, lanas minerales o espumas de poliuretano, pero con una notable reducción en peso, por lo que es ideal en aplicaciones donde el peso sea un factor significativo, como construcciones navales, aeronáuticas o edificaciones ligeras.These benefits are superior to or comparable to those achieved with acoustic and anti-thermal panels made of viscoelastic wool, geotextiles, mineral wool or polyurethane foam, but with a notable reduction in weight, making it ideal in applications where weight is a significant factor. such as shipbuilding, aeronautics or light buildings.

Al mismo tiempo, la invención plantea un uso alternativo de los restos sobrantes de procesos productivos de espuma de melamina que hasta la fecha debían ser depositados en vertederos, con lo que se fomenta modelo de producción y consumo que implica reutilizar y reciclar materiales existentes para crear un valor añadido. De esta forma, el ciclo de vida de los productos se extiende.At the same time, the invention proposes an alternative use of the leftover remains of melamine foam production processes that to date had to be deposited in landfills, thus promoting a production and consumption model that involves reusing and recycling existing materials to create an added value. Of In this way, the life cycle of the products is extended.
