Description
Dämmvliesstoff ohne oder mit synthetischer Stützfaser unter 10 Prozent.Insulating nonwoven fabric with or without synthetic support fibers less than 10 percent.
Die Erfindung betrifft einen Dämmvliesstoff, der ohne oder mit nur geringem Anteil an synthetischen Stützfasern versehen ist. Der Dämmvliesstoff besteht aus Naturfasern, vorzugsweise Hanffasern, die unter Beimischung von Fermenten und einem umweltfreundlichen Brandschutz voluminös in einem Thermofusionsverfahren in einer Rohdichte von 20 - 25 kg/m gebunden wird, einem Wasserdampfdiffusionswiderstand von 1-2&mgr;, eine Wärmeleitfähigkeit von 0,035 - 0,039 W/mK und eine Sorptionsfeuchte von 7% aufweist. Der Dämmvliesstoff ist Schimmelfest, erreicht die Brandschutzklasse B2 und kann dem Anwendungstyp W + WL zugeordnet werden. Zur Steigerung der Druckfestigkeit kann eine synthetische Stützfaser von 8% beigemischt werden.The invention relates to an insulating nonwoven fabric that contains no or only a small proportion of synthetic supporting fibers. The insulating nonwoven fabric consists of natural fibers, preferably hemp fibers, which are bound in a thermofusion process with the addition of ferments and an environmentally friendly fire protection agent to produce a bulk density of 20 - 25 kg/m, a water vapor diffusion resistance of 1-2μ, a thermal conductivity of 0.035 - 0.039 W/mK and a sorption moisture content of 7%. The insulating nonwoven fabric is mold-proof, achieves fire protection class B2 and can be assigned to the application type W + WL. To increase the compressive strength, a synthetic supporting fiber of 8% can be added.
Dämmvliesstoffen werden bisher vorwiegend aus Mineralfasern oder aus Naturfasern mit Synthetikfaseranteilen über 10%, hergestellt und sind somit ökologisch nicht immer einwandfrei. Die synthetische Faser wird zum Verkleben der Fasern benutzt. Da Dämmstoffe in der Regel als Dämmung oder Isolierung, vorzugsweise im Dachbereich Anwendung finden, ist die Brandschutzklasse B2 erforderlich. Die hat zur Folge, dass der hohe synthetische Anteil im Vlies einen Brandschutzanteil von 15% und mehr erfordert. Hier werden aus Kostengründen Brandschutzmittel mit hohem Salzanteil (Borate) oder andere umweltschädliche Stoffen belastet sind.Insulating fleeces are currently mainly made from mineral fibers or natural fibers with synthetic fiber content of more than 10%, and are therefore not always ecologically sound. The synthetic fiber is used to bond the fibers together. Since insulating materials are generally used as insulation, preferably in roof areas, fire protection class B2 is required. This means that the high synthetic content in the fleece requires a fire protection content of 15% or more. For cost reasons, fire retardants with a high salt content (borates) or other environmentally harmful substances are used here.
Erfinderaufgabe war es daher, einen Dämmvliesstoff zu entwickeln, der keine, oder weniger synthetische Faseranteile als 10% beinhaltet daher ökologisch unbedenklich ist und so auf umweltfeindliche Brandschutzmittel ganz oder teilweise verzichtet werden konnte.The inventor's task was therefore to develop an insulating nonwoven material that contains no or less than 10% synthetic fiber content and is therefore ecologically harmless, thus making it possible to completely or partially dispense with environmentally harmful fire retardants.
Dies ist mit der Entwicklung des Dämmvliesstoffes ohne oder mit nur geringem Anteil an synthetischen Stützfasern gelungen. Der Dämmvliesstoff ist voll verrottbar und erfüllt sonst alle Aufgaben der bisherigen Dämmstoffe.This has been achieved with the development of the insulating fleece with no or only a small proportion of synthetic supporting fibers. The insulating fleece is completely biodegradable and otherwise fulfills all the functions of previous insulating materials.

Der Vorteil gegenüber den bisherigen Dämmstoffen liegt neben der Verrottbarkeit auch in der Hautverträglichkeit beim Verarbeiten und in der Herstellung, da er aus langen Hanffasern hergestellt ist. Kurze, wie in der Mineralwolle vorkommende Fasern, die Atemwege beeinträchtigen konnten nicht festgestellt werden.The advantage over previous insulation materials is not only its degradability but also its skin compatibility during processing and production, as it is made from long hemp fibers. Short fibers, such as those found in mineral wool, which impair the respiratory tract, could not be detected.
Ein Vorteil liegt im Einsatz eines flüssigen Systems. Hier wird eine mehrfunktionale Wirkung in Bezug präzise Verteilung der Substanzen für Brandschutz und Verkleben erzielt und macht gleichzeitig ein separates aber auch nachträgliches Auftragen möglich. Gleichzeitig werden hierbei erhebliche Herstellungskosten eingespart.One advantage is the use of a liquid system. This achieves a multifunctional effect in terms of precise distribution of the substances for fire protection and bonding, while also making separate or subsequent application possible. At the same time, considerable production costs are saved.
Durch die naturgegebene Schall und Wärmeisolierung kann der Dämmvliesstoff überall dort eingebaut werden, wo auf Wärme- oder Schallschutz besonderer Wert gelegt wird.Due to its natural sound and heat insulation properties, the insulating fleece can be installed anywhere where particular importance is placed on heat or sound insulation.
