Abstract
Description
Die Erfindung bezieht sich auf ein
flächiges Brandhemmungsmaterial
nach dem Oberbegriff des Anspruches 1. Ein derartiges Material ist
beispielsweise aus der
Bei all diesen Materialien besteht nämlich das Problem, daß sie im Brandfall – sei durch die Hitze, sei es durch ein sie erweichendes Löschmittel – fließfähig werden und daher die Tendenz haben, an einer vertikalen Fläche der Schwerkraft zu folgen. Der Begriff "fließfähig" sei hier im allgemeinsten Sinne verstanden, der auch fließfähig im Sinne eines Schüttgutes verstanden, das etwa flockig oder pulvrig sein kann. Denn gerade blähfähige Materialien werden beim Aufblähen bloß aufgelockert, ohne in einen flüssigen oder teigigen Zustand überzugehen.All of these materials exist namely that Problem that they in case of fire - be through the heat, be it through a softening extinguishing agent - become fluid and therefore tend to be on a vertical surface of the Gravity to follow. The term "flowable" is the most general here Understood the senses, which is also fluid in the sense bulk goods understood that can be flaky or powdery. Because straight expandable materials when inflating just loosened up, without being in a liquid or pasty state.
Der Effekt ist dann, daß sich das den Brand hemmende Material irgendwo an der Unterseite ansammelt, während ja doch die Hitze gerade oben größer als unten ist. Im Falle einer freiliegenden Brandhemmungsschicht kann das Material abfallen und dann überhaupt nicht mehr zur Verfügung stehen. Dies Problem besteht also besonders bei aufschäumenden oder sich aufblähenden Materialien, weil mit der Volumenvergrößerung ja auch der Abstand – und somit die Verringerung der Adhäsion – zum Trägermaterial zunimmt.The effect is then that the fire retardant material accumulates somewhere on the bottom, while yes the heat just bigger than above is below. In the case of an exposed fire retardant layer the material fall off and then at all no longer available stand. So this problem is particularly with foaming or bloating Materials, because with the volume increase the distance - and therefore the reduction in adhesion - to the carrier material increases.
Der Erfindung liegt deshalb die Aufgabe zugrunde, insbesondere in vertikaler Läge anzubringendes, Brandhemmungsmaterial besser zu stabilisieren und an seinem Orte zu halten bzw. ein Abwärtsfließen zu verhindern. Dies gelingt erfindungsgemäß dadurch, daß die Schicht mindestens noch einen zweiten porösen flächigen Träger aufweist. Während als beim oben genannten Stand der Technik die Schicht zwischen zwei Trägerschichten gelegen hatte (die jeweils dem ersten Träger entsprechen), soll nun erfindungsgemäß die Schicht von Brandhemmungsmaterial selbst den zweiten Träger beinhalten, d.h. sie hat ihn inkorporiert innerhalb der Brandhemmungsschicht.The object of the invention is therefore the basis, in particular fire-retardant material to be installed in a vertical position stabilize better and keep it in place or prevent it from flowing downwards. According to the invention, this is achieved by that the Layer has at least a second porous flat carrier. While as in the above-mentioned prior art, the layer between two Base layers located had (the first carrier according to the invention, the layer of fire retardant material should now even the second carrier include, i.e. she incorporated it within the fire retardant layer.
Aus den oben genannten Gründen ist es in Weiterbildung der Erfindung vorteilhaft, wenn die Merkmale des Anspruches 2 verwirklicht sind.For the reasons stated above it is advantageous in a further development of the invention if the features of claim 2 are realized.
Im Gegensatz zu den das Brandhemmungsmaterial tragenden beiden Außenschichten des Standes der Technik ist es vorteilhaft, wenn von den Merkmalen des Anspruches 3 Gebrauch gemacht wird. Man erhält so praktisch eine einzige, beidseitig mit Brandhemmungsmaterial beschichtete Lage. Dabei sei auch erwähnt, daß damit die Lagerhaltung und die Manipulation mit einem solchen Material in festem Zustand vereinfacht ist.In contrast to the the fire retardant material bearing two outer layers of the prior art, it is advantageous if of the features of claim 3 is made use of. You practically get one Layer coated on both sides with fire retardant material. Be there also mentioned that with that warehousing and manipulation with such a material is simplified in the solid state.
An sich kann das Trägermaterial sehr verschieden sein, beispielsweise auch ein poröser Kunststoff, gegebenenfalls auch ein Drahtgewebe oder -gitter, insbesondere im Falle des ersten Trägers. Bevorzugt ist jedoch ein Textilmaterial.In itself, the carrier material be very different, for example a porous plastic, optionally also a wire mesh or mesh, especially in Trap of the first carrier. However, a textile material is preferred.
Ferner ist es vorteilhaft, wenn zur Verbesserung der Kohärenz der Schichten dem Brandhemmungsmaterial Fasern beigemengt sind, denn solche Fasern geben nicht nur der Schicht des Brandhemmungsmaterial einen inneren Halt, sondern greifen auch noch in die Poren der Träger ein und verbinden so die Schicht aus Brandhemmungsmaterial mit dem jeweiligen Träger.It is also advantageous if for Improve coherence the layers of fibers are added to the fire retardant material, because such fibers not only give the layer of fire retardant material an inner hold, but also engage in the pores of the wearer and thus connect the layer of fire retardant material with the respective one Carrier.
An sich könnten beide porösen flächigen Träger gleich ausgebildet sein. Es hat sich jedoch als vorteilhaft herausgestellt, wenn die Poren des zweiten porösen. flächigen Trägers größer sind als die des ersten porösen flächigen Trägers, vorzugsweise mindestens doppelt so groß. Da sich nämlich der zweite Träger bei Aufblähung des Brandhemmungsmaterials mit diesem vom ersten Träger weg bewegen wird, gestatten es seine großen Poren, daß eine Kohärenz des Brandhemmungsmaterials durch die Poren hindurch – insbesondere, wenn dieses Material auch noch mit sich teilweise durch die Poren hindurch erstreckenden kurzen Fasern vermengt ist – erhalten bleibt und verhindert, daß das Brandhemmungsmaterial abwärts fließt.As such, both porous flat supports could be the same be trained. However, it has proven to be advantageous when the pores of the second porous. flat carrier are larger than that of the first porous flat support preferably at least twice as large. Because the second one carrier with bloating of the fire retardant material away from the first carrier its large pores allow a coherence of the Fire retardant material through the pores - especially if this Material also with partially extending through the pores short fibers is mixed - preserved stays and prevents that Fire retardant material downwards flows.
