Description

Aus mit Bitumen überzogener Metallfolie bestehende Isolierbahn Vorliegende Erfindung betrifft eine Verbesserung der bekannten aus mit Bitumen überzogenen Metallfolien bestehenden Isolierbahnen, welche Bauwerke gegen Eindringen von Wasser schützen. Es ist die Befürchtung ausgesprochen worden, daB die Haltbarkeit solcher Isolierbahnen vielleicht durch Haarrisse gefährdet wird, die sich im Laufe der Jahre möglicherweise in dem. Bitumenüberzug bilden. Aluminium wird beispielsweise durch Lauge und kalkhaltiges Wasser angegriffen, welches durch einen HaarriB Zugang zur Folie hätte. Da edlere Metalle durchweg Importgüter darstellen, ist es in der Regel nicht ohne weiteres möglich, eine Metallfolie aus einem edlen Metall als Träger für die Isolierbahn zu nehmen. Ein weiterer Grund, welcher die Verwendung eines edleren Metalls für die Metallfolie verbietet, kann darin liegen, daB das edlere Metall nicht die für eine Isolierbahn erforderlichen mechanischen Eigenschaften besitzt.The existing insulation sheet made of bitumen-coated metal foil The invention relates to an improvement of the known bitumen-coated metal foils existing insulating sheets, which protect structures against the ingress of water. Fear has been expressed that the durability of such insulating sheets Perhaps at risk from hairline cracks that may develop over the years by doing. Form bitumen coating. Aluminum is made up of lye and calcareous, for example Water attacked, which would have access to the foil through a hairline. There are nobler ones Metals consistently represent import goods, it is usually not without further ado possible, a metal foil made of a noble metal as a carrier for the insulating strip gain weight. Another reason for using a nobler metal for the metal foil prohibits, may be that the nobler metal is not the one for an insulating sheet has the required mechanical properties.

Der Erfinder schlägt zur Lösung der Aufgabe vor, Isolierbahnen, welche aus beiderseitig mit Bitumen überzogenen Metallfolien bestehen, dadurch völlig korrosionsfest zu machen, daß als Metallfolien plattierte Aluminiumfolien Verwendung finden. Unter Plattieren ist bekanntlich das Überziehen mit einer dünnen Schicht eines edleren Metalls zu verstehen. Zur Herstellung einer solchen dünnen Schicht kommt beispielsweise Kupfer in Frage, welches z. B. auf galvanischem Wege auf die Aluminiumfolie aufgebracht werden kann.To solve the problem, the inventor proposes insulating strips, which consist of metal foils coated with bitumen on both sides, making them completely corrosion-resistant to make that clad aluminum foils are used as metal foils. Under Plating is known to be the coating with a thin layer of a noble one To understand metal. For example, such a thin layer is produced Copper in question, which z. B. applied by electroplating to the aluminum foil can be.

Eine mit Kupfer plattierte Aluminiumfolie hat den Vorteil, daß das Aluminium der Folie die erforderliche Zugfestigkeit verleiht, während das Kupfer das Aluminium vor korrodierenden Angriffen schützt.An aluminum foil clad with copper has the advantage that the Aluminum gives the foil the necessary tensile strength, while the copper which protects aluminum from corrosive attacks.
