BeschreibungDescription
Die Erfindung betrifft eine Dachbahn zur Abdeckung von Dächern und Gebäudeteilen, besteht aus einem beschichteten Vliesmaterial mit einer Deckschicht aus Polymerbitumen und einer mineralischen Bestreuung.The invention relates to a roofing membrane for covering roofs and parts of buildings, consisting of a coated nonwoven material with a covering layer of polymer bitumen and a mineral coating.
Derartige Dachbahnen bestehen aus einem Vliesmaterial, das ihnen die erforderliche mechanische Festigkeit verleit. Zur Abweisung zur Witterungseinflüssen, insbesondere von Regen und Feuchtigkeit, ist eine beidseiti— ge wasserundurchlässige Beschichtung vorgesehen. Als Beschichtung wird üblicherweise ein Polymerbiturnen verwendet, mit dem das Vliesmaterial innig getränkt wird.Such roofing membranes are made of a fleece material that gives them the necessary mechanical strength. To repel the effects of the weather, especially rain and moisture, a waterproof coating is provided on both sides. A polymer biturn is usually used as the coating, with which the fleece material is thoroughly saturated.
Die Polymere weisen eine hohe Elastizität auf und können dadurch witterungs- und temperaturbedingte Ausdehnungsschwankungen ausgleichen. Nachteilig dabei ist je— doch ihre Empfindlichkeit gegenüber ultravioletter Strahlung. UV—Strahlung führt zu einer Verhärtung der Polymere, was wiederum ihre Dehnungseigenschaften erheblich mindert und die Lebensdauer einer derartigen Dachbahn erheblich einschränkt.The polymers are highly elastic and can therefore compensate for fluctuations in expansion caused by weather and temperature. However, the disadvantage is their sensitivity to ultraviolet radiation. UV radiation causes the polymers to harden, which in turn significantly reduces their expansion properties and significantly limits the service life of such a roof membrane.
Zum Schutz gegen mechanische Beschädigungen der Deckschicht ist diese mit einer mineralischen Bestreuung versehen, üblicherweise werden Schiefersplitt, Sand oder Gesteingranulate verwendet. Diese Materialien reflektieren Licht, wodurch eine temperaturbedingte Längenveränderung zumindest teilweise kompensiert werden kann. Maßgeblich für die Lebensdauer einer Dachbahn istTo protect the top layer against mechanical damage, it is covered with a mineral coating, usually slate chippings, sand or stone granules. These materials reflect light, which can at least partially compensate for a temperature-related change in length. The decisive factor for the service life of a roof membrane is
jedoch ihre Beständigkeit gegenüber Ultraviolettstrahlung. however, their resistance to ultraviolet radiation.
Aufgabe der Erfindung ist es, eine Dachbahn der eingangs beschriebenen Art zu schaffen, die einen verbesserten Schutz der Deckschicht gegenüber ultravioletter Strahlung aufweist.The object of the invention is to create a roofing membrane of the type described above which has improved protection of the covering layer against ultraviolet radiation.
Gelöst wird diese Aufgabe dadurch, daß die Bestreuung aus einer Schwermetallschlacke besteht. Durch diese Maßnahmen wird eine Dachbahn geschaffen, die mit einer Bestreuung versehen ist, die Ultraviolettstrahlung verstärkt reflektiert. Dadurch wird die UV-Belastung der in die Deckschicht eingelagerten Polymere verringert und ihre Alterung verzögert. Derartige Dachbahnen bleiben langer elastisch und können temperaturbedingten Längenschwankungen wirkungsvoller und langer kompensieren. Die Lebensdauer einer derartiger Dachbahn wird dadurch wesentlich vergrößert.This task is solved by the fact that the coating consists of a heavy metal slag. This measure creates a roofing membrane that is coated with a coating that reflects ultraviolet radiation more strongly. This reduces the UV load on the polymers embedded in the top layer and delays their aging. Such roofing membranes remain elastic for longer and can compensate for temperature-related length fluctuations more effectively and for longer. The service life of such a roofing membrane is therefore significantly increased.
Weitere vorteilhafte Maßnahmen sind in den übrigen Unteransprüchen beschrieben. Die Erfindung ist anhand eines Ausführungsbeispieles in der beiliegenden Zeichnung dargestellt und wird nachfolgend näher beschrieben.Further advantageous measures are described in the remaining subclaims. The invention is illustrated using an embodiment in the accompanying drawing and is described in more detail below.
In der einzigen Figur ist der Schnitt durch eine erfindungsgemäße Dachbahn 10 dargestellt. Die Dachbahn 10 besteht im wesentlichen aus einem die Festigkeit tragenden Vliesmaterial 11 , daß üblicherweise aus einem Kunststoff besteht.The single figure shows a section through a roofing membrane 10 according to the invention. The roofing membrane 10 consists essentially of a nonwoven material 11 that provides strength and is usually made of a plastic.
Das Vlies 11 ist innig mit Bitumen getränkt und mit einer verschweißbaren Unterbeschichtung 12 und einer ebenfalls verschweißbaren Oberbeschichtung 13 versehen. Eine solche Dachbahn 10 dient der wasserdichten Abdeckung eines - nicht dargestellten - Daches, üblicherweise eines Flachdaches.The fleece 11 is thoroughly impregnated with bitumen and provided with a weldable undercoating 12 and a likewise weldable topcoating 13. Such a roofing membrane 10 serves to provide a waterproof covering of a roof (not shown), usually a flat roof.
Zur Verbesserung der Dehnungseigenschaften sind Polymerteilchen 14 in die Beschichtungen 12 und 13 eingelagert. Zum Schutz gegen mechanische Beanspruchung ist die Oberbeschichtung 12 des Vlieses 11 mit einer Bestreuung 15 versehen.To improve the stretch properties, polymer particles 14 are embedded in the coatings 12 and 13. To protect against mechanical stress, the top coating 12 of the fleece 11 is provided with a sprinkling 15.
Als Bestreuung 15 ist erfindungsgemäß ein Granulat aus einer Kupferschlacke vorgesehen. Mit diesem Kupferschlackengranulat kann UV-Strahlung besser reflektiert und damit eine Versprödung der eingelagerten PoIymerteilchen 14 verlangsamt werden.According to the invention, a granulate made of a copper slag is provided as the sprinkling 15. This copper slag granulate can reflect UV radiation better and thus slow down the embrittlement of the embedded polymer particles 14.
Das Kupferschlackengranulat der Bestreuung 15 weist eine Körnung von vorzugsweise 0,5 bis 1,4 mm auf und ist mit einer glatten oder glasigen Oberfläche versehen. Es wird in bekannter Weise bei der Produktion bei erhöhter Temperatur in die bitumöse Matrix der Oberbeschichtung 12 eingebracht. Nach dem Abkühlen ist die Bestreuung 15 innig mit der Oberbeschichtung 12 verbunden.The copper slag granulate of the sprinkling 15 has a grain size of preferably 0.5 to 1.4 mm and is provided with a smooth or glassy surface. It is introduced into the bituminous matrix of the top coating 12 in a known manner during production at an elevated temperature. After cooling, the sprinkling 15 is intimately connected to the top coating 12.
