Abstract

A damp-proof sheet for the sealing of buildings having a barrier layer for water and water vapour is described. The damp-proof sheet contains at least one biaxially stretch-oriented and thermoset sheet of thermoplastic material which is metallised on at least one side. In addition, a method of preventing the ingress of moisture into heat insulating layers of buildings is described. In this method, a biaxially stretch-oriented, thermoset sheet of thermoplastic material which is metallised on at least one side is arranged between the masonry or the outer facing of the building and the heat insulating material to be protected.

Description

Die vorliegende Erfindung betrifft eine Dichtungsbahn für die Bauwerksabdichtung mit einer Sperrschicht für Wasser und Wasserdampf.The present invention relates to a sealing membrane for sealing buildings with a barrier layer for water and water vapor.

Lang andauernde Einwirkung von Wasser und Wasserdampf kann bekanntlich die Qualität und Lebensdauer einer Wär­meisolierung an Dächern oder Wänden von Bauwerken, die üblicherweise aus geschäumten Kunststoffen oder Stein­wolle besteht, beträchtlich mindern. Deshalb werden zum Schutz solcher Wärmedämmschichten in der Praxis zusätzli­che Dichtungsbahnen vorgesehen. Für viele Anwendungen lassen allerdings die üblichen Dichtungsbahnen noch zu wünschen übrig.Long-term exposure to water and water vapor can, as is well known, considerably reduce the quality and service life of thermal insulation on roofs or walls of buildings, which usually consists of foamed plastics or rock wool. Therefore, additional sealing sheets are provided in practice to protect such thermal insulation layers. For many applications, however, the usual sealing sheets still leave something to be desired.

Aus der EP-A-0 045 893 ist eine bituminöse Dichtungsbahn für die Dachabdeckung bekannt, die eine Sperrschicht aus Kunststoff-Metall-Verbundfolie enthält. Aluminium ist je­doch ein teurer und energieintensiver Rohstoff, und es besteht das Bestreben, hier wirksame Einsparungen vorzu­sehen, ohne daß aber die Sperrwirkung der Dichtungsbahn nachläßt.From EP-A-0 045 893 a bituminous sealing membrane for the roof covering is known, which contains a barrier layer made of plastic-metal composite foil. However, aluminum is an expensive and energy-intensive raw material, and efforts are being made to make effective savings here, but without the barrier action of the sealing membrane being reduced.

Aufgabe der Erfindung war es daher, eine Dichtungsbahn für die Bauwerksabdichtung, insbesondere zum Schutz von Wärmedämmschichten, zu schaffen, die eine wirksame Sperre gegenüber Wasser und Wasserdampf darstellt und die gleichzeitig in großem Umfang preisgünstig und umwelt­freundlich herzustellen ist.The object of the invention was therefore to provide a sealing membrane for the sealing of buildings, in particular for the protection of thermal insulation layers, which represents an effective barrier against water and water vapor and which at the same time is inexpensive and environmentally friendly to manufacture.

Gelöst wird diese Aufgabe durch eine Dichtungsbahn der eingangs genannten Gattung, deren Kennzeichenmerkmal dar­in besteht, daß die Dichtungsbahn wenigstens eine biaxial streckorientierte und hitzefixierte Folie aus thermopla­stischem Kunststoff enthält, die wenigstens einseitig me­tallisiert ist.This object is achieved by a sealing membrane of the type mentioned at the outset, the distinguishing feature of which is that the sealing membrane contains at least one biaxially stretch-oriented and heat-fixed film made of thermoplastic material which is metallized on at least one side.

Als thermoplastischer Kunststoff sind prinzipiell alle Kunststoffe geeignet, die sich zu biaxial orientierten Folien verarbeiten lassen. Beispiele hierfür sind Poly­olefine, Polystyrol, Polyamide, Polyvinylchlorid oder Polyester. Bevorzugt im Rahmen der Erfindung sind Poly­olefine, insbesondere Polypropylen, und Polyester, insbe­sondere Polyethylenterephthalat.In principle, all plastics that can be processed into biaxially oriented films are suitable as thermoplastic. Examples include polyolefins, polystyrene, polyamides, polyvinyl chloride or polyester. In the context of the invention, preference is given to polyolefins, in particular polypropylene, and polyesters, in particular polyethylene terephthalate.

Als eine Metallisierung soll im Rahmen der Erfindung eine ultradünne Metallbelegung einer Oberfläche verstanden werden, die üblicherweise durch Metallaufdampfung im Vakuum erzeugt wird. Die Dicke der Metallisierung liegt im Bereich von 20 bis 200 nm, als Metalle können Zink, Aluminium, Eisen, Chrom, Nickel u. a. verwendet werden, wobei Aluminium bevorzugt ist.In the context of the invention, metallization is understood to mean an ultra-thin metal coating on a surface which is usually produced by metal vapor deposition in a vacuum. The thickness of the metallization is in the range from 20 to 200 nm, as metals zinc, aluminum, iron, chromium, nickel and the like. a. can be used, aluminum being preferred.

In einer bevorzugten Ausführungsform der erfindungsge­mäßen Dichtungsbahn ist die Metallisierung durch eine zu­sätzlich auf der freien Oberfläche der Metallisierung an­geordnete Kunststoffschicht vor mechanischer Beschädigung geschützt. Diese Schutzschicht kann aus Polyethylen, Polypropylen oder aus Polyester bestehen. Sie kann durch Aufkaschieren (Aufkleben) oder durch Aufextrudieren auf­gebracht werden.In a preferred embodiment of the sealing membrane according to the invention, the metallization is protected from mechanical damage by an additional plastic layer arranged on the free surface of the metallization. This protective layer can consist of polyethylene, polypropylene or polyester. It can be applied by lamination (gluing) or by extrusion.

Wenn die erfindungsgemäße Dichtungsbahn für die Dachab­deckung Verwendung finden soll, kann sie ein- oder beid­seitig mit einer Bitumenschicht kombiniert werden.If the sealing membrane according to the invention is to be used for the roof covering, it can be combined on one or both sides with a bitumen layer.

Für manche Anwendungszwecke ist es wünschenswert, einen Flammschutz für die erfindungsgemäße Dichtungsbahn vorzu­sehen. Dafür kann in einer besonderen Ausgestaltung der Erfindung der Rohstoff für die biaxial streckorientierte und hitzefixierte Folie zusätzlich flammhemmende Mittel enthalten. Solche Mittel sind üblicherweise Verbindungen, die Halogene, Phosphor oder Aluminium in jeweils wirksa­men Konzentrationen enthalten.For some applications it is desirable to provide flame protection for the sealing membrane according to the invention. For this purpose, in a special embodiment of the invention, the raw material for the biaxially stretch-oriented and heat-fixed film can additionally contain flame-retardant agents. Such agents are usually compounds which contain halogens, phosphorus or aluminum in effective concentrations in each case.

Darüber hinaus können dem Kunststoff Additive wie z. B. UV-Stabilisatoren zugefügt werden, falls die Dichtungs­bahn bei ihrem bestimmungsgemäßen Einsatz der direkten Witterung und dem Sonnenlicht ausgesetzt werden soll.In addition, the plastic additives such. B. UV stabilizers are added if the geomembrane is intended to be exposed to direct weather and sunlight when used as intended.

Die Dichtungsbahn wird gemäß der Erfindung so zwischen dem Mauerwerk oder der äußeren Bauwerksverkleidung und dem zu schützenden Wärmedämmaterial angeordnet, daß ein wirksamer Schutz gegen das Eindringen von Feuchtigkeit in das Wärmedämmaterial gewährleistet ist. Hierzu ist es vorteilhaft, die erfindungsgemäße Dichtungsbahn in Über­lappungsbereichen mit geeigneten Klebern, die insbeson­dere auch witterungsbeständig sein sollen, zu verkleben. Die Verwendung der erfindungsgemäßen biaxial streckorien­tierten, hitzefixierten und metallisierten Dichtungsbahn zur Verhinderung des Eindringens von Feuchtigkeit in Wär­medämmschichten bei Bauwerken ist deshalb besonders vor­ teilhaft, weil die erfindungsgemäße Dichtungsbahn wegen der Streckorientierung eine besonders gute Reißfestigkeit besitzt und weil sie infolge der Hitzefixierung auch eine ausreichend hohe Dimensionsstabilität unter der Einwir­kung üblicher witterungsbedingter Temperaturunterschiede über einen Zeitraum von mehreren Jahren gewährleistet.According to the invention, the sealing membrane is arranged between the masonry or the outer building cladding and the thermal insulation material to be protected in such a way that effective protection against the penetration of moisture into the thermal insulation material is ensured. For this purpose, it is advantageous to glue the sealing membrane according to the invention in overlap areas with suitable adhesives, which in particular should also be weather-resistant. The use of the biaxially stretch-oriented, heat-fixed and metallized sealing membrane according to the invention to prevent the penetration of moisture into thermal insulation layers in buildings is therefore particularly advantageous Partly because the geomembrane according to the invention has a particularly good tensile strength due to the stretch orientation and because it also ensures a sufficiently high dimensional stability over the course of several years due to the heat fixation under the influence of usual weather-related temperature differences.
