Description

Streckbares DichtbandStretchable sealing tape

Die Erfindung betrifft ein streckbares Dichtband mit geschlossener Oberfläche und zumindest einer unterseitigen Klebeschicht, wobei die Oberfläche aus einer Metallfolie besteht. Derartige Dichtbänder lassen sich an strukturierte Flächen anformen und werden für Abdichtungs- und Verpackungszwecke eingesetzt.The invention relates to a stretchable sealing tape with a closed surface and at least one underside adhesive layer, wherein the surface consists of a metal foil. Such sealing tapes can be molded on structured surfaces and are used for sealing and packaging purposes.

Im Stand der Technik sind zahlreiche Dichtbänder aus Butylkautschuk oder ähnlichen Klebstoffen bekannt, die mit Metallfolien aus Aluminium oder Kupfer kaschiert sind.Numerous sealing tapes of butyl rubber or similar adhesives are known in the art, which are laminated with metal foils of aluminum or copper.

Sie werden vielfältig bei Abdichtungen in allen Bereichen eingesetzt wie zum Beispiel als Dampfsperrschicht bei der Fenstermontage. Diese Dichtbänder sind im allgemeinen etwa 0,8 bis 1,5 mm dick, wobei die Dicke der Metallfolie bei 0,030 bis 0,150 mm liegt. Die Folien haben im allgemeinen eine glatte oder genoppte Oberfläche und lassen nur sehr geringe Dehnungen zu. In vielen Fällen wäre jedoch eine größere Dehnmöglichkeit wünschenswert, um Vorsprünge oder Unebenheiten zu überbrücken.They are widely used in sealing applications in all areas, such as vapor barrier coatings for window installation. These sealing tapes are generally about 0.8 to 1.5 mm thick, wherein the thickness of the metal foil is 0.030 to 0.150 mm. The films generally have a smooth or dimpled surface and allow only very small strains. In many cases, however, a greater Dehnmöglichkeit would be desirable to bridge protrusions or bumps.

Aus DE 102 30 552 A1 ist ein streckbares Bahnmaterial bekannt. Hierbei wird eine dünne Metallfolie mit einem reissfesten Vlies oder Gewebe beschichtet und anschliessend durch Kreppen quer zur beabsichtigten Streckrichtung mit kleinen Falten versehen. Hierdurch entsteht ebenfalls eine zerklüftete Oberfläche, die das Verkleben von mehreren Bahnen erschwert und aufgrund der Kapillarwirkung besondere Massnahmen bei Abdichtungen erforderlich macht. Ausserdem benötigt der Kreppvorgang mehr Material als für die vorgesehene Streckung mindestens erforderlich wäre, da wegen der unregelmässigen Oberflächenausbildung ein gewisser Überschuss vorhanden sein muss.Out DE 102 30 552 A1 is a stretchable web material known. Here, a thin metal foil is coated with a tear-resistant non-woven or fabric and then provided by creping transversely to the intended direction of stretching with small wrinkles. This also creates a rugged surface that makes it difficult to glue multiple webs and due to the capillary action makes special measures in sealing required. In addition, the creping process requires more material than would be at least necessary for the intended stretch, since a certain excess must be present because of the irregular surface formation.

Gekreppte Alufolien ermöglichen große Dehnungen bei geringen Zugkräften, was neben der guten Verformbarkeit aber auch den Nachteil hat, dass eine so genannte Mikrofalte von etwa 0,1 mm auf 1-2 mm d.h. bis auf das 10- oder 20- fache gedehnt werden kann. Solche extremen örtlichen Dehnungen können nicht gleichmäßig auf die benachbarten Schichten übertragen werden, sondern es können unter der Folie Ablösungen oder Risse entstehen, die zu unerwünschten Kapillareffekten führen.Creped aluminum foils allow high elongation at low tensile forces, which in addition to the good deformability but also has the disadvantage that a so-called micro-fold of about 0.1 mm to 1-2 mm, that can be stretched to 10 or 20 times. Such extreme local strains can not be uniform to the neighboring ones Layers are transferred, but it can cause delamination or cracks under the film, which lead to undesirable capillary effects.

Von MAGE Herzberg GmbH aus DE 04916 Herzberg wird ein "Flex-Alu" genanntes Abdichtband angeboten, das aus einem etwa 0,2 mm dicken lackierten Aluminiumblech besteht, das quer zur Streckrichtung im Abstand von etwa 6 mm ca. 3 mm tiefe Wellen aufweist. Das gewellte Blech hat auf der Unterseite zusätzlich eine glatt durchlaufende Klebeschicht aus Butylkautschuk von ca. 1 mm Dicke sowie eine Trennfolie. Es ist einleuchtend, dass die durch die 3 mm hohen und 6 mm langen Wellen gebildeten Wellentäler bei Überlappungen auch bei sorgfältiger Verlegung des Abdichtbandes nicht durch eine 1 mm dicke Butylschicht abgedichtet werden können. Eine ähnliche Anordnung beschreibt DE 199 14 071 U1 . Hier wird vorgeschlagen, dass die Unterseite des gewellten Alublechs vollständig mit Butylkautschuk ausgefüllt wird und noch ein geringer Kleberüberschuss die unteren Scheitellinien des gewellten Blechs bedeckt, sodass eine geschlossene Klebefläche unabhängig von der Höhe der Profilierung erzeugt wird. Die Höhe der Überdeckung der unteren Scheitellinien ist jedoch offensichtlich nicht ausreichend, um eine dichte Verbindung zu garantieren, wenn eine solche schwach überdeckte Scheitellinie auf einem Wellental eines darunter liegenden zweiten Dichtbandes aufliegt und angepresst wird, zumal die Wellenhöhe hierbei relativ hoch ist.From MAGE Herzberg GmbH DE 04916 Herzberg is offered a "Flex-Alu" called sealing tape, which consists of an approximately 0.2 mm thick painted aluminum sheet, which has about 3 mm deep shafts transverse to the direction of stretching at a distance of about 6 mm. The corrugated sheet has on the bottom in addition a smooth continuous adhesive layer of butyl rubber of about 1 mm thickness and a release film. It is obvious that the troughs formed by the 3 mm high and 6 mm long waves can not be sealed by a 1 mm thick butyl layer in the case of overlaps, even with careful laying of the sealing tape. A similar arrangement describes DE 199 14 071 U1 , Here it is proposed that the underside of the corrugated aluminum sheet is completely filled with butyl rubber and still a slight excess of adhesive covers the lower crest lines of the corrugated sheet, so that a closed adhesive surface is produced regardless of the height of the profiling. However, the level of overlap of the lower crest lines is obviously not sufficient to guarantee a tight connection, when such a weakly covered crest line rests on a trough of an underlying second sealing strip and is pressed, especially since the wave height is relatively high.

Aufgabe der vorliegenden Erfindung ist es, ein dehnbares Dichtband zur Verfügung zu stellen, das eine geschlossene Metalloberfläche aufweist und auch bei Überlappungen eine dichte Verbindung gewährleistet, somit eine einfache Montage ermöglicht und so das Risiko eines Schadens minimiert. Grundgedanke der Erfindung ist, eine geschlossene Metallfolie einzusetzen und dabei hohe örtliche Dehnungen zu vermeiden, indem die Folie so fein gewellt wird, dass die darunter liegende Klebeschicht wesentlich dicker als die Wellenhöhe der Folie ist. Dies wird dadurch erreicht, dass die Metallfolie wie bei einer "Feinstwelle" bei der Wellpappherstellung gewellt wird und die Oberfläche einen nahezu geschlossenen Eindruck macht.The object of the present invention is to provide an expandable sealing strip which has a closed metal surface and, even with overlaps, ensures a tight connection, thus enabling simple assembly and thus minimizing the risk of damage. The basic idea of the invention is to use a closed metal foil and to avoid high local strains by the film being so finely corrugated that the underlying adhesive layer is substantially thicker than the wave height of the foil. This is achieved by the metal foil as in a "fine wave" in the Corrugated cardboard production is curled and the surface makes a nearly closed impression.

Erfindungsgemäß wird vorzugsweise eine Aluminiumfolie von ca. 0,050 Dicke mit ca. 0,4 mm hohen und etwa 1,2 mm langen Wellen versehen. Hiermit können Dichtbänder von insgesamt unter 1,0 mm Dicke hergestellt werden, die leicht von Hand zu dehnen sind und im Überlappungsbereich durch leichtes Andrücken dicht miteinander verbunden werden können. Die Aluminiumfolie kann mit einer eingefärbten Acrylatschicht oder einem ähnlichen Lack zur farblichen Anpassung oder zur Verbesserung der Witterungsbeständigkeit beschichtet werden.According to the invention, an aluminum foil of approximately 0.050 thickness is preferably provided with shafts approximately 0.4 mm high and approximately 1.2 mm long. This sealing strips can be made with a total of less than 1.0 mm thickness, which are easy to stretch by hand and can be tightly connected in the overlap area by lightly pressing. The aluminum foil may be coated with a colored acrylate layer or similar varnish for color matching or weathering resistance.

Die Klebeschicht auf der Unterseite ist vorzugsweise eine Kautschukklebemasse, es können jedoch auch Acrylkleber, Haftschmelzkleber, Bitumen oder spezielle reaktivierbare Klebesysteme verwendet werden. Es ist auch denkbar, die Wellentäler mit einem preiswerten Material wie z.B. einem hochgefüllten Schmelzkleber zu füllen und eine dünne Klebefolie, eventuell auch nur an den Rändern, darunter anzubringen. Der Schmelzkleber hat außerdem den Vorteil, dass er mit Heißluft vor Ort verklebt werden kann.The adhesive layer on the underside is preferably a rubber adhesive, but acrylic adhesives, hot melt adhesives, bitumen or special reactive adhesive systems may also be used. It is also conceivable that the troughs with a cheap material such. To fill a highly filled hot melt adhesive and a thin adhesive film, possibly even at the edges, underneath to install. The hot melt adhesive also has the advantage that it can be glued on site with hot air.

Um die Reißfestigkeit einer dünnen Metallfolie für die Deckschicht zu erhöhen, die ansonsten alle Funktionen erfüllen würde, kann dieselbe auch mit einer Kunststoff-Folie, einem Kunststoff-Vlies oder anderen organischen Fasern verstärkt werden. Grundsätzlich kann die Deckschicht auch aus einer nichtmetallischen, notfalls bedampften Folie wie z.B. einer Polyester- oder Acrylatfolie bestehen, wenn sie auf die Rückstellkräfte der Klebeschicht abgestimmt ist. In besonderen Fällen können aus dem Dichtband auch Formteile wie z.B. Schürzen für Dachfenster hergestellt werden.In order to increase the tear strength of a thin metal foil for the cover layer, which would otherwise fulfill all the functions, it can also be reinforced with a plastic film, a plastic non-woven or other organic fibers. In principle, the cover layer can also be made of a non-metallic, if necessary vapor-deposited film, such as e.g. a polyester or acrylate film, if it is matched to the restoring forces of the adhesive layer. In special cases, molded parts such as e.g. Aprons for roof windows are made.
