Description

Die Erfindung betrifft ein Dichtungsband zur Abdichtung von Fugen in der Bauindustrie mit einem Kern aus weichem Schaumstoff, der eine erste und eine zweite Außenfläche aufweist, wobei auf mindestens einer der Außenflächen als Überdehnungsschutz eine Zugverstärkungsschicht aufgebracht ist.The invention relates to a sealing tape for sealing joints in the construction industry a core made of soft foam, which has a first and a second outer surface, a tensile reinforcement layer on at least one of the outer surfaces as protection against overexpansion is applied.

Derartige Dichtungsbänder werden seit Jahren in der Bauindustrie zur Abdichtung von Fugen verwendet. Vor allem bei der Herstellung von Sandwichelementen, großvolumigen Bauteilen mit zwei Metallhäuten, zwischen die Polyurethanschaum eingespritzt wird, der die beiden Metallhäute miteinander verklebt, werden Dichtungsbänder schon beim Ausschäumen verwendet, um als seitliche Abdichtung den Schaumaustritt zu verhindern. Das Dichtungsband bleibt im Anschluß an die Fertigung normalerweise dauerhaft mit dem Sandwichelement verbunden und wird beim Zusammenfügen zweier Sandwichelemente unter Kompression gesetzt, wodurch sich der Schaum optimal an die Fugenflanke anschmiegt und die Fuge perfekt verfüllt wird. Derartige Dichtungsbänder bestehen beispielsweise aus Polyurethanschaum, der durch Tränkung mit einer wässrigen Acrylatdispersion imprägniert ist. Eine Zugverstärkungsschicht kann zusätzlich als Überdehnungsschutz dienen.Such sealing tapes have been used in the construction industry for years to seal joints used. Especially in the production of sandwich elements, large volume Components with two metal skins, between which polyurethane foam is injected, which the two metal skins glued together, sealing tapes are already when foaming used to prevent foam leakage as a side seal. The sealing tape usually remains permanently with the sandwich element after production connected and is put together when joining two sandwich elements Compression set, whereby the foam nestles optimally on the joint flank and the joint is filled perfectly. Such sealing tapes consist, for example Polyurethane foam, which is impregnated with an aqueous acrylic dispersion is. A tensile reinforcement layer can also serve as protection against overexpansion.

Manchmal ist es erforderlich, Dichtungsbänder wieder ganz oder teilweise aus der Fuge des noch nicht endgültig montierten Sandwichelements zu entfernen. Grund hierfür ist z.B. die Montage eines Fingerklemmschutzes bei beweglichen Elementen. Fugendichtungsbänder nach dem Stand der Technik lassen sich meist nur schwer aus der Fuge entfernen, da sie sich nicht am Stück abziehen lassen, sondern einreißen oder zumindest Teile des Dichtungsbandes in der Fuge hinterlassen. Andere Dichtungsbänder wiederum bilden keine ausreichende Haftung zur Schaumfüllung des Sandwichelements aus und fallen bei der Bearbeitung derselben aus der Fuge heraus.Sometimes it is necessary to completely or partially remove sealing tapes from the joint to remove the sandwich element that has not yet been finally installed. The reason for this is e.g. the installation of a finger protection against moving elements. Joint sealing tapes According to the state of the art, it is usually difficult to remove from the joint because they can not be pulled off in one piece, but tear or at least parts of the Leave the sealing tape in the joint. Other sealing tapes in turn do not form sufficient adhesion to the foam filling of the sandwich element and fall off at Machining the same out of the joint.

Es ist daher die Aufgabe der vorliegenden Erfindung, ein Dichtungsband zu schaffen, das eine sichere Abdichtung während des Ausschäumvorgangs des Sandwichelements gewährleistet, gut am Sandwichelement haftet und sich dennoch bei Bedarf nach der Fertigung des Sandwichelements leicht ganz oder teilweise aus der Fuge entfernen läßt. It is therefore the object of the present invention to provide a sealing tape which ensures a secure seal during the foaming process of the sandwich element, adheres well to the sandwich element and still adheres to it if necessary after production easily or partially remove the sandwich element from the joint.

Diese Aufgabe wird durch die Merkmale des Anspruchs 1 gelöst.This object is solved by the features of claim 1.

Dadurch, daß auf der zumindest einen Zugverstärkungsschicht eine Folie befestigt ist, die geeignete Gleitmittel enthält und derart ausgestaltet ist, daß sie an einem Schaumstoffkörper haftet, jedoch leicht und rückstandsfrei wieder von diesem lösbar ist, erfüllt das Dichtungsband seine Aufgabe als Dichtungskörper sehr zuverlässig, kann aber bei Bedarf ohne großen Aufwand komplett oder teilweise aus der Sandwichelementfuge entfernt werden.Characterized in that a film is attached to the at least one tensile reinforcement layer, the contains suitable lubricants and is designed such that it on a foam body adheres, but can easily be removed from it without leaving any residue its job as a sealing body is very reliable, but can be done without great effort can be completely or partially removed from the sandwich element joint.

Der Schaumstoffkern besteht bevorzugt aus Polyurethan, wodurch aufgrund der elastischen Eigenschaften des Weichschaums und des daraus resultierenden Rückstellvermögens eine besonders sichere Abdichtung der Fuge gewährleistet wird.The foam core is preferably made of polyurethane, which is due to the elastic Properties of the soft foam and the resulting resilience a particularly secure seal of the joint is guaranteed.

Vorzugsweise ist der Schaumstoffkern imprägniert, wobei das Imprägnat eine die verzögerte Rückstellung des Schaumstoffs hervorrufende Eigenschaft aufweist, so daß das Dichtungsband auch bei hohem Kompressionsgrad eingesetzt werden kann.The foam core is preferably impregnated, the impregnate being the delayed one Resetting the foam-causing property, so that Sealing tape can also be used with a high degree of compression.

Als Imprägnat wird bevorzugt eine wässrige Acrylatdispersion verwendet, die das Raumgewicht des Dichtungsbandes etwa um das Dreifache erhöht und somit eine hervorragende Schallabsorption liefert.An aqueous acrylate dispersion, which has the density by weight, is preferably used as the impregnate of the sealing tape increased about three times and thus an excellent Provides sound absorption.

a preferred embodiment of a sandwich element with a sealing tape according to the invention.

In Fig. 1 ist eine bevorzugte Ausführungsform des erfindungsgemäßen Dichtungsbandes 1 dargestellt. Das Dichtungsband 1 ist ein länglicher Körper, der in Endlosproduktion hergestellt wird und üblicherweise auf Coils (Rollen) in Lauflängen von 20 m bis 1000 m aufgewickelt wird. Das Dichtungsband 1 weist einen Schaumstoffkern 3 auf, der aus einem elastischen Schaumstoff mit hohem Rückstellvermögen besteht. Vorzugsweise wird hierfür ein elastischer, offenzelliger Polyurethan-Weichschaum verwendet. Die Dicke eines solchen Schaumstoffkerns 3 beträgt zwischen 3 mm und 15 mm, seine Breite zwischen 5 mm und 150 mm.1 shows a preferred embodiment of the sealing tape 1 according to the invention shown. The sealing tape 1 is an elongated body, which is manufactured in continuous production is and usually wound on coils in lengths of 20 m to 1000 m becomes. The sealing tape 1 has a foam core 3, which consists of an elastic Foam with high resilience. This is preferably a elastic, open-celled polyurethane foam is used. The thickness of one Foam core 3 is between 3 mm and 15 mm, its width between 5 mm and 150 mm.

Der Schaumstoffkern 3 ist vorzugsweise mit einem Imprägnat getränkt, das eine die verzögerte Rückstellung des Schaumstoffs hervorrufende Eigenschaft aufweist. Bevorzugt wird ein Imprägnat auf Basis einer wässrigen Acrylatlösung verwendet, durch die das Dichtungsband 1 auch ein etwa dreimal höheres Raumgewicht erhält, so daß der getränkte Schaumstoffkern 3 Schall hervorragend absorbiert und somit im späteren Einsatz einen effektiven Schallschutz bewirkt.The foam core 3 is preferably impregnated with an impregnate, the one that is delayed Resetting the foam has property. Is preferred uses an impregnate based on an aqueous acrylate solution through which the sealing tape 1 also receives an approximately three times higher density, so that the soaked Foam core 3 absorbs sound excellently and therefore a later use effective sound insulation.

Der Schaumstoffkern 3 weist eine erste Außenfläche 5 auf, die beim Einbau dem Sandwichelement zugewandt sein soll, sowie eine zweite Außenfläche 7, die der ersten Außenfläche 5 gegenüberliegt. Zumindest auf der ersten Außenfläche 5 ist eine Zugverstärkungsschicht 4 aufgebracht, die als Überdehnungsschutz dient. Die Zugverstärkungsschicht 4 besteht aus einer verstärkenden Schicht aus plastischem Material, beispielsweise aus einem Acrylatüberzug, oder aus einem Gittergelege, das bevorzugt aus Glasfasern gebildet ist. Es ist auch möglich, beide Arten zu kombinieren.The foam core 3 has a first outer surface 5, which is the sandwich element during installation should be facing, and a second outer surface 7, that of the first outer surface 5 is opposite. At least on the first outer surface 5 is a tensile reinforcement layer 4 applied, which serves as protection against overexpansion. The tensile reinforcement layer 4 consists of a reinforcing layer of plastic material, for example one Acrylate coating, or from a scrim, which is preferably formed from glass fibers is. It is also possible to combine both types.

Auf der zumindest einen Zugverstärkungsschicht 4 ist eine Folie aufgebracht, die fest an der Zugverstärkungsschicht 4 haftet. Diese Folie 9 besteht vorzugsweise aus thermoplastischem Polyurethan, wobei auf der zur Zugverstärkungsschicht 4 hin gewandten Fläche als Klebemittel beispielsweise eine Heißklebefolie verwendet wird, um die sichere Verbindung zu gewährleisten. Aufgrund der Zusammensetzung der Folie 9 haftet diese zwar ausreichend an Schaumstoffen, läßt sich hiervon aber wegen geeigneter, in die Folie integrierter Gleitmittel wieder leicht und rückstandsfrei abziehen.. Die Folie 9 und/oder die Zugverstärkung 4 sollten derart dicht sein, daß beim Ausschäumen des Sandwichelements mit Polyurethanschaum dieser nicht in den Schaumstoffkern 3 eindringt bzw. durchschäumt. Der ausgehärtete Schaum würde ansonsten ein exaktes Aneinanderfügen von zwei Sandwichelementen im späteren Einsatz verhindern. Eine Temperaturstabilität von kurzzeitig bis zu 90°C wird aus Fertigungsgründen ebenfalls benötigt. Insgesamt sollte das Dichtungsband einen Fugendurchlaßkoeffizienten von unter 0,1 m3/hm aufweisen. A film is applied to the at least one tensile reinforcement layer 4 and adheres firmly to the tensile reinforcement layer 4. This film 9 is preferably made of thermoplastic polyurethane, for example a hot-melt film being used as the adhesive on the surface facing the tensile reinforcement layer 4 in order to ensure the secure connection. Because of the composition of the film 9, it adheres sufficiently to foams, but it can be removed easily and without residue because of suitable lubricants integrated into the film Sandwich elements with polyurethane foam that does not penetrate or foam through the foam core 3. The hardened foam would otherwise prevent two sandwich elements from being joined exactly when used later. A temperature stability of briefly up to 90 ° C is also required for manufacturing reasons. Overall, the sealing tape should have a joint permeability coefficient of less than 0.1 m 3 / hm.

Fig. 2 zeigt eine Anlage zur Herstellung von Sandwichelementen unter Verwendung eines erfindungsgemäßen Dichtungsbandes. Zunächst werden die beiden auf Coils aufgewickelten Metallhäute 11, 13 (aus Stahl- oder Aluminiumblech) abgewickelt, oberflächenbearbeitet 15 und mit einer Randprofilierung versehen 17, bei der die Nut- und Federgeometrien des jeweiligen Modells ausgebildet werden. Nach einer Vorheizung 19 der Metallhäute 11, 13 erfolgt die Ausschäumung 21 mit Polyurethanschaum, der in einer Dosieranlage 23 gemischt wird und über einen Rechen auf die untere Metallhaut 11 aufgetragen wird, dort aufschäumt und aushärtet, wodurch die beiden Metallhäute 11 und 13 verklebt werden. Zur Abdichtung der Längsfugen wird mindestens ein erfindungsgemäßes Dichtungsband 1 verwendet, das den Schaumaustritt verhindert. Das Dichtungsband 1 wird über jeweils der Form der Randprofilierung der Metallhäute 11, 13 und der Fugengeometrie angepaßte Klötze geführt und an den gewünschten Stellen positioniert. Die Klötze sind Einzelglieder einer Kette, der sog. Klotzkette 25. Das erfindungsgemäße Dichtungsband 1 ist hierzu auf einer Rolle (nicht gezeigt) aufgewickelt. Nach dem Verlassen der Schäumstation kann das Sandwichelement abgekühlt und zugeschnitten werden.Fig. 2 shows a plant for the production of sandwich elements using a sealing tape according to the invention. First, the two are wound on coils Metal skins 11, 13 (made of steel or aluminum sheet) unwound, surface processed 15 and provided with an edge profile 17, in which the tongue and groove geometries of the respective model. After preheating 19 of the metal skins 11, 13 is the foaming 21 with polyurethane foam, which is mixed in a metering system 23 and is applied to the lower metal skin 11 via a rake, foams there and hardens, whereby the two metal skins 11 and 13 are glued. to Sealing the longitudinal joints, at least one sealing tape 1 according to the invention is used, that prevents the foam from escaping. The sealing tape 1 is about each Adapted shape of the edge profile of the metal skins 11, 13 and the joint geometry Blocks led and positioned at the desired locations. The blocks are individual links a chain, the so-called block chain 25. The sealing tape 1 according to the invention is on this a roll (not shown) wound up. After leaving the foaming station it can Sandwich element can be cooled and cut.

In Fig. 3 ist ein Beispiel einer Verbindung von zwei bevorzugten Sandwichelementen 27 mit einem erfindungsgemäßen Dichtungsband 1 dargestellt. Die Sandwichelemente 27 zeigen jeweils die beiden Metallhäute 11, 13, zwischen denen eine Schaumstoffschicht 29 eingebracht ist. Das Dichtungsband 1 verschließt die Fuge 31 des Sandwichelements 27, so daß bei der Ausschäumung des Sandwichelements 27 kein Schaum austreten konnte. Zwischen Schaumstoffschicht 29 des Sandwichelements 27 und der Folie 9 des Dichtungsbandes 1 besteht eine haftende Verbindung. Der Zusammenbau von Sandwichelementen erfordert ein exaktes Fügen und Komprimieren der Dichtungsbänder. Oft werden bis zu 4 m hohe Sandwichelemente mit ebenso langer Fuge aufeinandergedrückt. Die Sandwichelemente werden schließlich mittels üblicher Befestigungsmittel wie Schrauben miteinander verbunden. Das Dichtungsband liefert die perfekte schalldämmende, witterungsfeste Abdichtung der Fuge. Längenänderungen der Dehnungsfuge werden ausgeglichen, so daß keine Risse oder eine mangelnde Haftung auftreten.3 shows an example of a connection of two preferred sandwich elements 27 to a sealing tape 1 according to the invention shown. The sandwich elements 27 show in each case the two metal skins 11, 13, between which a foam layer 29 is introduced is. The sealing tape 1 closes the joint 31 of the sandwich element 27, so that no foam could escape during the foaming of the sandwich element 27. Between Foam layer 29 of the sandwich element 27 and the film 9 of the sealing tape 1 there is an adhesive connection. The assembly of sandwich elements requires an exact joining and compression of the sealing tapes. Often up to 4 m high sandwich elements with an equally long joint pressed together. The sandwich elements are finally connected to each other using conventional fasteners such as screws connected. The sealing tape provides the perfect soundproofing, weatherproof seal the fugue. Changes in length of the expansion joint are compensated so that no cracks or lack of liability occur.

Aufgrund der Eigenschaften der Folie 9 kann das Dichtungsband aber auch ganz oder teilweise vor der endgültigen Montage aus der Fuge abgezogen werden, ohne daß Rückstände desselben in der Fuge verbleiben oder Stücke der Schaumstoffschicht 29 mit herausgezogen werden. Dies kann beispielsweise dann nötig sein, wenn ein Fingerklemmschutz bei beweglichen Elementen montiert werden soll. Due to the properties of the film 9, the sealing tape can also be wholly or partially be pulled out of the joint before final assembly without leaving any residue the same remain in the joint or pieces of the foam layer 29 are pulled out become. This may be necessary, for example, if finger protection is required movable elements to be mounted.

Das erfindungsgemäße Dichtungsband kann auch in anderen Variationen ausgestaltet werden, insbesondere sind Größenverhältnisse und geometrische Angaben nicht einschränkend. Oftmals werden auch zwei erfindungsgemäße Dichtungsbänder in einer Fuge angeordnet, die dann beim Aufeinanderpressen der Sandwichelemente aufeinander zu liegen kommen.The sealing tape according to the invention can also be designed in other variations , in particular size relationships and geometric information are not restrictive. Often, two sealing tapes according to the invention are also in a joint arranged, which then lie on each other when pressing the sandwich elements come.
