Abstract

A multilayered fabric which when used as support material for built-up roofing and sealing membranes shows not only good fire properties but also improved mechanical properties is obtained by needling together two preconsolidated fibre webs, one of which consists of synthetic fibres and the other of mineral fibres. The needling produces a strong positive bond between the two webs, which prevents the parting of the two layers under extreme thermomechanical conditions.

Description

Die vorliegende Erfindung betrifft einen Schichtstoff mit verbesserten mechanischen Eigenschaften und verbessertem Brandverhalten bei Einsatz als Trägerbahn für Dach- und Dichtungsbahnen. Solche Dach- und Dichtungsbahnen sind meist mit einer ein- oder beidseitigen Bitumenschicht versehen, können aber auch eine Beschichtung aus Elastomeren oder Plastomeren aufweisen.The present invention relates to a laminate with improved mechanical properties and improved fire behavior when used as a carrier sheet for roofing and sealing sheets. Such roofing and waterproofing membranes are usually provided with a bitumen layer on one or both sides, but can also have a coating of elastomers or plastomers.

Aus der DE-OS 32 26 041 ist es bekannt, auf ein loses, d.h. unverfestigtes, Mineralfaservlies eine dünne Schicht von ebenfalls losen Kunststoffasern aufzubringen und diesen Schichtstoff durch Nadeln zu verfestigen. Durch eine Hitzebehandlung ist es möglich, die Kunststoffasern mit den Mineralfasern zu verschmelzen. Durch dieses Verschmelzen werden formstabile Mineralfaserblankets erhalten.From DE-OS 32 26 041 it is known to refer to a loose, i.e. unconsolidated, mineral fiber fleece to apply a thin layer of also loose plastic fibers and to consolidate this laminate with needles. Heat treatment makes it possible to fuse the plastic fibers with the mineral fibers. This fusing results in stable mineral fiber blanks.

Als Trägerbahn für Dachbahnen ist ein Schichtstoff aus einem Synthesefaservlies und einem Mineralfaservlies aus dem DE-GM 77 39 489 bekannt. Die beiden Vliesschichten aus synthetischem und mineralischem Fasermaterial sind dort durch Binden oder Kleben miteinander verbunden. Verwendet werden hierzu thermoplastische und vernetzende Duromere.A laminate of a synthetic fiber fleece and a mineral fiber fleece from DE-GM 77 39 489 is known as a carrier web for roofing membranes. The two non-woven layers made of synthetic and mineral fiber material are bonded to one another there by binding or gluing. Thermoplastic and crosslinking thermosets are used for this.

Solche Trägerbahnen führen zu Dach- und Dichtungsbahnen mit hinreichend hoher Verarbeitungsstabilität beim Bituminieren und bei der Verlegung. Ihre Dimensionsstabilität erlaubt sogar einlagige Verlegung auf dem Dach. Das Brandverhalten dieser Dachbahnen nach DIN 4102, Teil 7, ist durch die Mineralfaserschicht deutlich verbessert.Such carrier sheets lead to roofing and waterproofing sheets with sufficiently high processing stability when bituminizing and laying. Their dimensional stability even allows single-layer installation on the roof. The fire behavior of these roofing membranes according to DIN 4102, part 7, is significantly improved by the mineral fiber layer.

Trägerbahnen aus Mischvliesen aus mineralischen und synthetischen Fasern, wie sie im DE-GM 77 23 547 beschrieben sind, ergeben dagegen keine nennenswerte Verbesserung des Brandverhaltens.Carrier sheets made of mixed nonwovens made of mineral and synthetic fibers, as described in DE-GM 77 23 547, however, do not result in any noteworthy improvement in fire behavior.

Als einziger Nachteil der bekannten Schichtstoffe aus einer mineralischen und einer synthetischen Faserschicht bleibt die Neigung zur Delaminierung der beiden Schichten unter extremen thermomechanischen oder mechanischen Bedingungen.The only disadvantage of the known laminates consisting of a mineral and a synthetic fiber layer remains the tendency to delaminate the two layers under extreme thermomechanical or mechanical conditions.

Es ist daher Aufgabe der vorliegenden Erfindung unter Wahrung aller Vorteile der bekannten Schichtstoffe für Trägerbahnen für Dach- und Dichtungsbahnen, auch noch diesen Nachteil zu überwinden.It is therefore an object of the present invention, while maintaining all the advantages of the known laminates for carrier sheets for roofing and sealing sheets, to overcome this disadvantage.

Erfindungsgemäß besteht deshalb der als Trägerbahn für Dach- und Dichtungsbahnen geeignete Schichtstoff aus einem vorverfestigten Synthesefaservlies und einem vorverfestigten Mineralfaservlies, die durch Vernadelung miteinander verbunden sind.According to the invention, therefore, the laminate suitable as a carrier sheet for roofing and sealing sheets consists of a pre-consolidated synthetic fiber fleece and a pre-consolidated mineral fiber fleece, which are connected to one another by needling.

Das Synthesefaservlies besteht bevorzugt aus Polyesterfasern, meist aus Polyäthylenterephthalat. Besonders bevorzugt werden Filamentvliesstoffe, sogenannte spunbonds, wie sie z.B. in der DE-OS 24 60 755 beschrieben werden, die ihrerseits durch Vernadelung oder sonstige an sich bekannte Verfahren vorverfestigt sind. Für die Vorverfestigung durch Vernadeln genügt hierbei eine Vernadelungsstichzahl von ca. 10 % der zur Verbindung der beiden Schichten des erfindungsgemäßen Schichtstoffs benötigten Gesamtstichzahl. Bevorzugte Flächengewichte der Filamentvliesstoffe liegen zwischen 50 und 350 g/m', die Einzeltiter zwischen 3 und 8 dtex, speziell zwischen 4 und 6 dtex.The synthetic fiber fleece preferably consists of polyester fibers, usually of polyethylene terephthalate. Filament nonwovens, so-called spunbonds, as are e.g. are described in DE-OS 24 60 755, which in turn are pre-consolidated by needling or other methods known per se. For pre-consolidation by needling, a number of needling stitches of about 10% of the total number of stitches required to connect the two layers of the laminate according to the invention is sufficient. Preferred basis weights of the filament nonwovens are between 50 and 350 g / m ', the individual titers between 3 and 8 dtex, especially between 4 and 6 dtex.

Als Mineralfaservlies werden Glasfaservliese bevorzugt, speziell in Form von Stapelfaservliesen. Besonders haben sich naß gelegte Stapelfaservliese bewährt. Bewährt haben sich aber auch Vliesstoffe aus keramischen Fasern. Das Vliesgewicht der Mineralfaservliese liegt meist zwischen 10 und 100 g/m2, bevorzugt zwischen 30 und 60 g/m2. Derartige Vliese beschreiben z.B. die EP-OS 19 465, die EP-OS 25 115 oder die DE-OS 31 43 586. Zur Herstellung des erfindungsgemäßen Schichtstoffs werden die beiden vorverfestigten Vliese nach den bekannten Verfahren miteinander vernadelt. Die Vernadelung soll 10 bis 100 Stiche/cm2, bevorzugt zwischen 20 und 50 Stichen/cm2, betragen. Dabei erfolgt die Vernadelung so, daß die Nadeln zuerst in das Synthesefaservlies einstechen und dann das darunterliegende Mineralfaservlies durchdringen. Die Stichtiefe richtet sich selbstverständlich nach den Vliesstärken. Sie liegt zwischen 6 und 11 mm und führt zu einer festen formschlüssigen Verbindung des Synthesefaservlieses mit dem Mineralfaservlies mit Hilfe der durch letzteres durchgezogenen Synthesefasern.Glass fiber fleeces are preferred as mineral fiber fleece, especially in the form of staple fiber fleeces. Wet-laid staple fiber nonwovens have proven particularly useful. Nonwovens made from ceramic fibers have also proven their worth. The nonwoven weight of the mineral fiber nonwovens is usually between 10 and 100 g / m 2 , preferably between 30 and 60 g / m 2 . Such nonwovens describe, for example, EP-OS 19 465, EP-OS 25 115 or DE-OS 31 43 586. To produce the laminate according to the invention, the two pre-consolidated nonwovens are needled using the known methods. The needling should be 10 to 100 stitches / cm 2 , preferably between 20 and 50 stitches / cm 2 . The needling is carried out in such a way that the needles first pierce the synthetic fiber fleece and then penetrate the mineral fiber fleece underneath. Of course, the stitch depth depends on the fleece thickness. It lies between 6 and 11 mm and leads to a firm, form-fitting connection of the synthetic fiber fleece with the mineral fiber fleece with the aid of the synthetic fibers pulled through the latter.

Die beigefügte Zeichnung zeigt einen Ausschnitt aus dem erfindungsgemäßen Schichtstoff. Dabei bedeutet 1 das Mineralfaservlies, 2 das Synthesefaservlies.The accompanying drawing shows a section of the laminate according to the invention. 1 means the mineral fiber fleece, 2 the synthetic fiber fleece.
