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 with a core of soft foam having a first and a second outer surface, wherein on at least one of the outer surfaces as an overstretch protection a Zugverstärkungsschicht 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 are used for years in the construction industry for sealing joints. Especially in the production of sandwich panels, large-volume components with two metal skins, is injected between the polyurethane foam, which glued the two metal skins together, sealing tapes are already used during foaming, as a lateral seal to prevent the foam leakage. The sealing strip normally remains permanently connected to the sandwich element after production and is compressed when two sandwich elements are joined, whereby the foam optimally adapts to the joint flank and the gap is filled in perfectly. Such sealing tapes consist for example of polyurethane foam, which is impregnated by impregnation with an aqueous acrylate dispersion. A tensile reinforcement layer can additionally serve as an overstretch protection.

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 remove sealing strips completely or partially from the joint of the not yet finally mounted sandwich element. The reason for this is e.g. the installation of a Fingerklemmschutzes with moving elements. Sealing tapes according to the prior art are usually difficult to remove from the joint, as they can not be deducted in one piece, but tear or at least leave parts of the sealing strip in the joint. Other sealing tapes in turn do not form sufficient adhesion to the foam filling of the sandwich element and fall out of the joint during the processing thereof.

Ein derartiges Dichtungselement ist beispielsweise aus der DE-A-196 09 277 bekannt. Das Dichtungsband weist einen Kern aus weichem Schaumstoff auf, der eine erste und eine zweite Außenfläche aufweist, die gegenüberliegend angeordnet sind, wobei auf der ersten Außenfläche eine Zugverstärkungsschicht aufgebracht ist, auf der wiederum eine Folie befestigt ist.Such a sealing element is known for example from DE-A-196 09 277. The sealing tape has a soft foam core having first and second outer surfaces disposed opposite one another, with a tensile reinforcing layer on the first outer surface, to which a film is in turn attached.

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 of the sandwich element, adheres well to the sandwich element and can still be easily or completely removed from the joint as needed after the manufacture of the sandwich element.

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 on the at least one Zugverstärkungsschicht a film is attached, which contains suitable lubricant and is designed such that it adheres to a foam body, but easily and residue-free of this solvable, the sealing tape fulfills its task as a sealing body very reliable, can but can be completely or partially removed from the Sandwichelementfuge if necessary without much effort.

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 ensures a particularly secure sealing of the joint due to the elastic properties of the flexible foam and the resulting resilience.

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.Preferably, the foam core is impregnated, the impregnate having a delayed recovery of the foam causing property, so that the sealing tape can be used even at high 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.As an impregnate, an aqueous acrylate dispersion is preferably used, which increases the density of the sealing tape about three times and thus provides excellent sound absorption.

Further details, features and advantages of the present invention will become apparent from the following description with reference to the drawings. Hereby shows:

a preferred embodiment of the sealing strip according to the invention;

a plant for the production of sandwich panels; and
Fig. 3
a preferred embodiment of a sandwich element with a sealing strip 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.In Fig. 1, a preferred embodiment of the sealing strip 1 according to the invention is shown. The sealing tape 1 is an elongated body, which is produced in endless production and usually wound on coils (rolls) in run lengths of 20 m to 1000 m becomes. The sealing tape 1 has a foam core 3, which consists of a resilient foam with high resilience. Preferably, an elastic, open-cell flexible polyurethane foam is used for this purpose. The thickness of such a 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 having a delayed recovery of the foam causing property. Preferably, an impregnate based on an aqueous acrylate solution is used, through which the sealing strip 1 also receives an approximately three times higher density, so that the impregnated foam core 3 absorbs sound excellent and thus causes an effective sound insulation in later use.

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 intended to face the sandwich element during installation, and a second outer surface 7, which lies opposite the first outer surface 5. At least on the first outer surface 5, a Zugverstärkungsschicht 4 is applied, which serves as overstretch protection. The Zugverstärkungsschicht 4 consists of a reinforcing layer of plastic material, such as an acrylate coating, or from a Gittergelege, which is preferably formed from glass fibers. 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.On the at least one tensile reinforcement layer 4, a film is applied, which adheres firmly to the Zugverstärkungsschicht 4. This film 9 is preferably made of thermoplastic polyurethane, wherein, for example, a heat-adhesive film is used as an adhesive on the surface facing the Zugverstärkungsschicht 4 in order to ensure the secure connection. Due to the composition of the film 9, although this sufficiently adheres to foams, but it can be deducted easily and without residue because of suitable, integrated in the film lubricant again. The film 9 and / or the tensile reinforcement 4 should be so dense that when foaming the Sandwich element with polyurethane foam that does not penetrate into the foam core 3 or foamed. The cured foam would otherwise prevent an exact joining of two sandwich elements in the later use. Temperature stability of up to 90 ° C for a short time is also required for production 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 strip according to the invention. First, the two wound on coils metal skins 11, 13 (made of steel or aluminum sheet) unwound, surface-treated 15 and provided with an edge profiling 17, in which the tongue and groove geometries of each model are formed. After a preheating 19 of the metal skins 11, 13, the foaming 21 with polyurethane foam, which is mixed in a metering system 23 and applied to the lower metal skin 11 via a rake, foams and cures there, whereby the two metal skins 11 and 13 are glued. To seal the longitudinal joints at least one inventive sealing tape 1 is used, which prevents the foam outlet. The sealing tape 1 is guided over each of the shape of the edge profiling of the metal skins 11, 13 and the joint geometry adapted blocks and positioned at the desired locations. The blocks are individual links of a chain, the so-called block chain 25. For this purpose, the sealing strip 1 according to the invention is wound on a reel (not shown). After leaving the foaming station, the 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.FIG. 3 shows an example of a connection of two preferred sandwich elements 27 with a sealing strip 1 according to the invention. The sandwich elements 27 each show the two metal skins 11, 13, between which a foam layer 29 is introduced. 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 strip 1 is an adhesive connection. The assembly of sandwich elements requires an exact joining and compression of the sealing strips. Often up to 4 m high sandwich elements are pressed together with equally long joint. The sandwich elements are finally connected together by means of conventional fastening means such as screws. The sealing tape provides the perfect soundproof, weatherproof seal of the joint. Length changes of the expansion joint are compensated, so that no cracks or a lack of adhesion 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 but the sealing strip can also be withdrawn in whole or in part before the final assembly of the joint, without residues thereof remain in the joint or pieces of the foam layer 29 are pulled out with. This may be necessary, for example, when a Fingerklemmschutz is to be mounted on movable elements.

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 strip according to the invention can also be configured in other variations, in particular, size relationships and geometric details are not restrictive. Often two sealing strips according to the invention are arranged in a joint, which then come to rest on each other when the sandwich elements are pressed against one another.
