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. Längenänderungen der Dehnungsfuge werden durch das Dichtungsband aufgenommen, so daß keine Risse oder Haftversagen auftreten, die eine Funktionalität der Fuge in Frage stellen würden. 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 elements, large-volume components with two metal skins, is injected between the polyurethane foam, which glued the two metal skins together, sealing strips 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. Length changes of the expansion joint are absorbed by the sealing strip, so that no cracks or adhesive failure occur that would compromise a functionality of the joint. 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.

Bei der Anbringung der auf großen Coils (Rollen) aufgewickelten Dichtungsbänder an Fugen mit schwierigen Geometrien ist es oftmals erforderlich, zusätzlich zur exakten Führung und Positionierung des Dichtungsbandes mittels der sogenannten Klotzkette, Klebebänder als Führungshilfe zu verwenden, um eine feste Haftung des Dichtungsbandes an mindestens einer der Metallhäute zu erzeugen, bevor die Ausschäumung des Sandwichelements stattfindet. Dadurch soll vermieden werden, daß aufgrund von unzulänglichem Abdichten Schaum austritt, der ein ordnungsgemäßes Fügen der Elemente auf der Baustelle verhindert.When attaching wound on large coils (rolls) sealing strips on joints with difficult geometries, it is often necessary to use in addition to the exact guidance and positioning of the sealing strip by means of the so-called block chain, adhesive tapes as a guide to a firm adhesion of the sealing strip to at least one the metal skins to produce before the foaming of the sandwich element takes place. This is to avoid that escapes due to insufficient sealing foam, which prevents proper joining of the elements on the site.

Diese Klebebänder werden bislang in einer separaten Vorrichtung an die Zugverstärkungsschicht des Dichtungsbandes und an eine Metallhaut des Sandwichelements im Fugenbereich geklebt. Hierdurch entsteht zusätzlicher Aufwand, der den Ausschäumungsprozess des Sandwichelements verkompliziert und Mehrkosten verursacht.These adhesive tapes are so far in a separate device to the Zugverstärkungsschicht the sealing tape and glued to a metal skin of the sandwich element in the joint area. This creates additional expense that complicates the foaming process of the sandwich element and causes additional costs.

Aus der EP-A-0 399 952 ist ein Dichtungsband mit einem Kern aus weichem Schaumstoff bekannt, der eine erste und eine zweite Außenfläche aufweist, die gegenüberliegend angeordnet sind, wobei auf der ersten Außenfläche eine Zugverstärkungsschicht aufgebracht ist, auf der wiederum ein doppelseitig haftendes Klebeband angeordnet ist. Das Klebeband ist auf beiden Seiten gleichermaßen klebrig ausgestaltet.From EP-A-0 399 952 there is known a sealing tape having a soft foam core having first and second outer surfaces disposed opposite one another with a tensile reinforcing layer applied to the first outer surface, on which in turn a double-sided adhesive Adhesive tape is arranged. The tape is equally tacky on both sides.

Es ist daher die Aufgabe der vorliegenden Erfindung, ein Dichtungsband zu schaffen, das auch bei Sandwichelementfugen mit komplizierter Geometrie ohne weitere Bearbeitung eine sichere Abdichtung während des Ausschäumvorgangs gewährleistet, das einfach und kostengünstig herstellbar ist und sich zudem problemlos auf Rollen auf- und abwickeln läßt.It is therefore an object of the present invention to provide a sealing strip, which ensures a secure seal during the foaming even with Sandwichelementfugen with complicated geometry without further processing, which is easy and inexpensive to produce and also easy to roll up and unwind.

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

Dadurch, daß auf der Zugverstärkungsschicht ein doppelseitig haftendes Klebeband angeordnet ist, das auf der zur ersten Außenfläche des Schaumstoffkerns hingewandten Seite stark haftend und auf der anderen Seite schwächer haftend ausgestaltet ist, wobei die schwächer haftende Seite des Klebebands derart ausgestaltet ist, daß sie auf Blech haftet, jedoch nicht auf Schaumstoff, kann das Dichtungsband ohne Verwendung einer weiteren Vorrichtung direkt auf der Metallhaut des Sandwichelements befestigt werden, wobei das Klebeband an der Zugverstärkungsschicht sehr fest und an der Metallhaut nur relativ leicht haftet.Characterized in that on the Zugverstärkungsschicht a double-sided adhesive tape is arranged, which is strongly adhesive on the side facing the first outer surface of the foam core side and weakly adhesive on the other side, wherein the weaker adhesive side of the adhesive tape is designed such that it on sheet metal adheres, but not on foam, the sealing tape can be attached directly to the metal skin of the sandwich panel without the use of another device, the tape adheres very firmly to the Zugverstärkungsschicht and the metal skin only relatively easily.

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.

Vorzugsweise bedeckt das Klebeband die Zugverstärkungsschicht nur teilweise, wodurch eine flexible Anpassung an die Geometrie der abzudichtenden Sandwichelementfuge gewährleistet wird.Preferably, the adhesive tape only partially covers the tensile reinforcement layer, thereby ensuring a flexible adaptation to the geometry of the sandwich element joint to be sealed.

Besonders gut eignet sich ein Klebeband, das durch beidseitige, unterschiedlich ausgestaltete Acrylatdispersionen inhärent klebrig ausgebildet ist, wobei die haftende Wirkung erhöht wird, wenn eine Acrylatdispersion einen geeigneten Anteil an einem Tackyfierharz aufweist.Particularly suitable is an adhesive tape, which is inherently tacky by double-sided, differently designed acrylate dispersions, wherein the adhesive effect is increased when an acrylate dispersion has a suitable proportion of a Tackyfierharz.

Weitere Einzelheiten, Merkmale und Vorteile der vorliegenden Erfindung ergeben sich aus der nachfolgenden Beschreibung unter Bezugnahme auf die Zeichnungen. Hierin zeigt:

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 is usually wound on coils (rolls) in run lengths of 20 m to 1000 m. 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, that of the first outer surface 5 opposite. 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.

Die Zugverstärkungsschicht 4 muß derart gestaltet sein, daß sie mit dem in Sandwichelementen enthaltenen Polyurethanschaum eine ausreichend haftende Verbindung herstellt. Zudem muß sie 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 1 einen Fugendurchlaßkoeffizienten von unter 0,1 m3/hm aufweisen.The tensile reinforcement layer 4 must be designed so that it produces a sufficiently adhesive connection with the polyurethane foam contained in sandwich elements. In addition, it must be so tight 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 later use. Temperature stability of up to 90 ° C for a short time is also required for production reasons. Overall, the sealing tape 1 should have a joint permeability coefficient of less than 0.1 m 3 / hm.

Auf der Zugverstärkungsschicht 4 ist ein doppelseitiges Klebeband 9 aufgebracht, das fest an der Zugverstärkungsschicht 4 haftet. Dieses Klebeband 9 besteht üblicherweise aus einer Folienträgerschicht und weist auf beiden Seiten jeweils ein unterschiedlich starkes Klebemittel auf, wobei die stärker klebende Schicht auf der zur Zugverstärkungsschicht 4 hin gewandten Fläche angeordnet ist, um die sichere Verbindung zu gewährleisten. Auf der anderen Seite ist das Klebeband 9 weniger stark haftend ausgebildet, so daß zwar eine ausreichende Haftung auf Metall erfolgt, jedoch keine Haftung auf Schaumstoffen.On the tensile reinforcing layer 4, a double-sided adhesive tape 9 is adhered, which firmly adheres to the tensile reinforcing layer 4. This adhesive tape 9 usually consists of a film carrier layer and has on both sides in each case a differently strong adhesive, wherein the more adhesive layer is arranged on the plane facing the Zugverstärkungsschicht 4 facing surface to ensure the secure connection. On the other hand, the adhesive tape 9 is formed less strongly adhesive, so that although a sufficient adhesion to metal takes place, but no liability to foams.

Als Klebemittel werden vorzugsweise Acrylatdispersionen verwendet, die inhärent klebrig ausgebildet sind. Je nach Wahl der Dispersion kann die Stärke der Haftung variiert werden, insbesondere sind Dispersionen aus n-Butyl-Acrylat, t-Butyl-Acrylat, Ethylhexylacrylat oder Cyclohexylacrylat für unterschiedliche Haftstärken geeignet. Zusätzlich können sog. Tackyfierharze in den Dispersionen enthalten sein, die deren Klebstärke erhöhen. Hierfür eignen sich beispielsweise Kolophoniumharze oder Kohlenwasserstoffharze. Ein bevorzugtes Mischungsverhältnis für die stark klebende Seite liegt bei ca. 70% Acrylat- und 30% Harzanteil. Je nach gewünschter Haftstärke können diese Prozentanteile beliebig geändert werden.The adhesives used are preferably acrylate dispersions which are inherently tacky. Depending on the choice of dispersion, the strength of the adhesion can be varied; in particular, dispersions of n-butyl acrylate, t-butyl acrylate, ethylhexyl acrylate or cyclohexyl acrylate are suitable for different adhesive strengths. In addition, so-called Tackyfierharze may be included in the dispersions, which increase their adhesive strength. Rosin resins or hydrocarbon resins are suitable for this purpose, for example. A preferred mixing ratio for the strongly adhesive side is about 70% acrylate and 30% resin content. Depending on the desired adhesive strength, these percentages can be changed as desired.

Das Klebeband 9 überdeckt meist nur einen Teil, in der Regel nicht mehr als 75% (obwohl auch dies möglich ist), bevorzugt etwa ein am Randbereich gelegenes Drittel, der Zugverstärkungsschicht 4. Ein Abdeckpapier für das Klebeband ist nicht nötig, wodurch unnötige Vorarbeiten bei der Herstellung von Sandwichelementen vermieden werden können.The adhesive tape 9 usually covers only a part, as a rule not more than 75% (although this is also possible), preferably a third located at the edge region, the tensile reinforcement layer 4. A masking paper for the adhesive tape is not necessary, whereby unnecessary preparatory work in the production of sandwich panels can be avoided.

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. Zur besseren Führung bei komplizierten Fugengeometrien wird das erfindungsgemäße Dichtungsband 1, das auf einer Rolle (nicht gezeigt) aufgewickelt ist, zusätzlich mittels des Klebebandes 9 an einer Metallhaut 11, 13 befestigt, um eine sichere Haftung zu gewährleisten. Eine Vorrichtung zum Auftragen des Klebebandes auf das Dichtungsband ist mit dem erfindungsgemäßen Dichtungsband 1 nicht mehr nötig. 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 is carried out with polyurethane foam, which is mixed in a metering system 23 and applied to the lower metal skin 11 via a rake, where it foams and hardens, 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 better guidance in complicated joint geometries, the sealing strip 1 according to the invention, which is wound on a roll (not shown), is additionally attached to a metal skin 11, 13 by means of the adhesive tape 9 to ensure a secure adhesion. A device for applying the adhesive tape to the sealing strip is no longer necessary with the sealing strip 1 according to the invention. 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 der Schaumstoffschicht 29 des Sandwichelements 27 und der Zugverstärkungsschicht 4 besteht eine haftende Verbindung. Zusätzlich ist im oberen Bereich der Zugverstärkungsschicht 4 ein Klebeband 9 angeordnet, das fest haftend mit der oberen Metallhaut 13 verbunden ist. Dieses Klebeband 9 sorgt für die sichere Führung des Dichtungsbandes 1 während des Ausschäumvorgangs des Sandwichelements 27. 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 the foam layer 29 of the sandwich element 27 and the Zugverstärkungsschicht 4 is an adhesive connection. In addition, an adhesive tape 9 is arranged in the upper region of the Zugverstärkungsschicht 4, which is firmly adhering to the upper metal skin 13 is connected. This adhesive tape 9 ensures the secure guidance of the sealing strip 1 during the foaming process of the sandwich element 27. 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.

Das erfindungsgemäße Dichtungsband kann auch in anderen Variationen ausgestaltet werden, insbesondere kann das Klebeband beliebige Geometrien aufweisen, wenn es die Form der Fuge erfordert.The sealing tape according to the invention can also be configured in other variations, in particular, the adhesive tape can have any geometry, if it requires the shape of the joint.

Claims (8)

  1. Sealing strip (1) having a core (3) of soft foam, which has a first (5) outer surface and a second (7) outer surface, which are arranged opposite one another, wherein at least on the first outer surface (5) is attached a tensile-reinforcing layer (4), on which in turn a double-sided adherent adhesive strip (9) is arranged, characterised in that the double-sided adherent adhesive strip (9) is designed to be strongly adherent on the side facing the tensile-reinforcing layer (4) and more weakly adherent on the other side, wherein the more weakly adherent side of the adhesive strip (9) is designed such that it adheres to sheet metal, but not to foam.
  2. Sealing strip (1) according to claim 1, characterised in that the foam core (3) consists of polyurethane.
  3. Sealing strip (1) according to claim 1 or 2, characterised in that the foam core (3) is impregnated, wherein the impregnate has a property which causes the delayed recovery of the foam.
  4. Sealing strip (1) according to claim 3, characterised in that the impregnate is an aqueous acrylate dispersion.
  5. Sealing strip (1) according to one of the preceding claims, characterised in that the adhesive strip (9) only partly covers the first outer surface (5) of the sealing strip (1).
  6. Sealing strip (1) according to one of the preceding claims, characterised in that the adhesive strip (9) is designed to be inherently tacky due to acrylate dispersions designed to be different on both sides.
  7. Sealing strip (1) according to claim 6, characterised in that at least one acrylate dispersion (9) has a suitable proportion of a tackifying resin.
  8. Sandwich element (27), which has two metal skins (11, 13), between which a foam layer (29) adhered to the latter is introduced, characterised in that at least one longitudinal side of the sandwich element (29) is sealed by a sealing strip (1) according to one of the preceding claims.
