Description

Die vorliegende Erfindung betrifft ein selbstklebendes Band zum Verschließen, Abdichten und Verkleben von Fugen im Hausbau, insbesondere von Fugen in Ecken oder Kanten. Derartige Klebebänder werden auch bezeichnet als Montageklebebänder, Dampfbremsklebebänder oder Dampfbremsfolien. Sie werden insbesondere benutzt zum Abdichten von Fugen zwischen Fenster- und Türrahmen und den entsprechenden Kanten der jeweiligen Wandöffnung. Es ist hierbei erforderlich, dass zum einen die Klebebänder auf unterschiedlichem Grund gut haften und zum anderen sich das selbstklebende Band leicht anbringen, d.h. verkleben läßt. Eine andere Anwendung von solchen selbstklebenden Bändern besteht in dem Abdichten von Fugen zwischen einzelnen Bauelementen, wie z.B. Ecken zwischen Hausaußenwänden. Die Dichtungsfunktion der Bänder besteht darin, die Fugen möglichst luftdicht und dauerhaft zu verschließen.The present invention relates to a self-adhesive tape for closing, sealing and bonding joints in house building, in particular joints in corners or edges. Such adhesive tapes are also referred to as mounting tapes, vapor barrier tapes or vapor barrier films. They are used in particular for sealing joints between window and door frames and the corresponding edges of the respective wall opening. It is necessary in this case that on the one hand the adhesive tapes adhere well on different grounds and on the other hand the self-adhesive tape can be easily attached, i. stick together. Another application of such self-adhesive tapes is in sealing joints between individual components, e.g. Corners between house exterior walls. The sealing function of the tapes is to close the joints as airtight and permanently as possible.

Solche Klebebänder weisen in der Regel eine Trägerschicht und eine mit dieser verbundene Klebeschicht auf, wobei die Klebeschicht mit einer abziehbaren Deckfolie als Schutz für den Kleber versehen ist. Nach dem Abziehen der Deckfolie wird das Band zunächst mit dem einen Fugenrand und anschließend mit dem anderen Fugenrand verklebt. Ein gattungsgemässes Klebeband, welches dem Oberbegriff des Anspruch 1 entspricht, ist aus US 4 977 718 A bekannt.Such adhesive tapes generally comprise a carrier layer and an adhesive layer bonded thereto, the adhesive layer being provided with a peelable cover film as protection for the adhesive. After removing the cover sheet, the tape is first glued to one edge of the joint and then to the other edge of the joint. A generic adhesive tape, which corresponds to the preamble of claim 1, is made US 4,977,718 A known.

Ein Problem derartiger Klebebänder besteht hierbei darin, dass die Klebeschicht für unterschiedliche Untergründe angepaßt sein muß. Beispielsweise muß die Klebeschicht ebenso gut auf Holz oder auf Kunststoff haften wie auch auf leicht porösem Untergrund wie z.B. Gips, Mauerputz, Beton oder Mauersteinen. Ein weiteres Problem besteht bei den bekannten Montageklebebändem darin, dass durch eine anschließende Weiterverarbeitung an der Oberseite des Klebebandes, z.B. durch Aufputzen von Mauerputz, die Gefahr besteht, dass sich das Klebeband von dem Untergrund löst und somit die abzudichtenden Fugen undicht werden.A problem of such adhesive tapes is that the adhesive layer must be adapted for different substrates. For example, the adhesive layer must adhere to wood or plastic as well as to slightly porous substrates such as plaster, plaster, concrete or masonry. Another problem with the known Montageklebebändem is that by subsequent further processing at the top of the tape, for example by brushing plaster, there is a risk that solves the tape from the ground and thus the joints to be sealed are leaking.

Es ist daher die Aufgabe der vorliegenden Erfindung, ein selbstklebendes Band zum Verschließen, Abdichten und Verkleben von Fugen bereitzustellen, welches in seinen Haftungseigenschaften hinsichtlich einer Weiterverarbeitung mit Putz oder dergleichen optimiert ist. Eine weitere Aufgabe der Erfindung ist das Bereitstellen eines selbstklebenden Bandes zum Abdichten von Fugen, welches kostengünstig herstellbar ist und dennoch eine gute und dauerhafte Dichtungsfunktion gewährleistet.It is therefore the object of the present invention to provide a self-adhesive tape for closing, sealing and bonding joints, which is optimized in its adhesion properties in terms of further processing with plaster or the like. Another object of the invention is to provide a self-adhesive tape for sealing joints, which is inexpensive to produce and yet ensures a good and durable sealing function.

Diese Aufgabe wird mit einem selbstklebenden Band gemäß den in Anspruch 1 genannten Merkmalen gelöst. Vorteilhafte Ausgestaltungen und Weiterbildungen sind Gegenstand der Unteransprüche.This object is achieved with a self-adhesive tape according to the features mentioned in claim 1. Advantageous embodiments and further developments are the subject of the dependent claims.

Das erfindungsgemäße Band weist eine Trägerschicht auf, auf welcher beispielsweise durch Beschichten eine Klebeschicht aufgetragen ist. Die Klebeschicht ihrerseits ist mit einer abziehbaren Deckfolie versehen, welche auch als Liner oder Schutz bezeichnet wird, um die Klebeschicht vor Schmutz und dergleichen zu schützen bzw. um ein Aufrollen des Klebebandes auch bei stark haftendem Kleber zu ermöglichen. Erfindungsgemäß weist das Band mindestens einen seitlichen Längsabschnitt auf, d.h. einen Bereich an einer Längsseite des Klebebandes, in welchem die Trägerschicht und die Klebeschicht perforiert ausgebildet sind. Perforiert heißt hier, dass mindestens eine Reihe von durchgehenden Öffnungen in der Trägerschicht und der Klebeschicht vorgesehen sind. Durch die Perforation wird die Klebehaftung des Bandes beim anschließenden Überputzen mit Mauerputz oder Gips oder dergleichen verbessert. Denn auf diese Weise haftet der Putz in den Öffnungen der Perforation direkt an dem Untergrund und verstärkt so die Haftung des Bandes auch auf porösem Untergrund. Es wird hierdurch vermieden, dass durch die Feuchtigkeit und das Gewicht von einer aufgetragenen Putzschicht oder dergleichen, das Band sich von dem Untergrund lösen kann und somit Undichtigkeiten entstehen bzw. die Putzschicht aufbrechen kann. Auch beim anschließenden Überkleben des Bandes mit einer Tapete oder mit Dekorationsplatten wird die Haftverbindung der Klebeschicht auf dem Untergrund verbessert. Die Perforation ist lediglich an einem seitlichen Längsabschnitt des Klebebandes vorgesehen, damit der mittige Klebebereich die Abdichtfunktion des Klebebandes sicher gewährleisten kann. Die Perforation des seitlichen Längsabschnittes des Klebebandes kann aus im wesentlichen runden, eckigen oder ovalen Öffnungen gebildet sein, welche vorzugsweise gleichmäßig verteilt angeordnet sind. Hierdurch wird erreicht, dass die Klebefunktion der Klebeschicht möglichst wenig beeinträchtigt wird und dennoch ein Hindurchdringen von einer auf das Klebeband aufzutragenden Schicht eines Materials durch die Öffnungen hierdurch an dem Untergrund, auf welchem das Klebeband aufgeklebt ist, haften kann.The tape according to the invention has a carrier layer on which, for example, by coating, an adhesive layer is applied. The adhesive layer in turn is provided with a peelable cover sheet, which is also referred to as a liner or protection to protect the adhesive layer from dirt and the like or to allow a rolling up of the adhesive tape even with strong adhesive. According to the invention, the band has at least one lateral longitudinal section, ie a region on a longitudinal side of the adhesive tape in which the carrier layer and the adhesive layer are perforated. Perforated means here that at least one row of through openings are provided in the carrier layer and the adhesive layer. Through the perforation, the adhesion of the tape is the subsequent overpainting with plaster or plaster or the like improved. Because in this way, the plaster adheres in the openings of the perforation directly to the ground and thus enhances the adhesion of the tape on a porous surface. It is thereby avoided that due to the moisture and the weight of a applied plaster layer or the like, the tape can be detached from the substrate and thus leaks or the plaster layer can break. Also during the subsequent gluing of the tape with a wallpaper or with decorative plates the adhesion of the adhesive layer on the substrate is improved. The perforation is provided only at a lateral longitudinal section of the adhesive tape, so that the central adhesive region can ensure the sealing function of the adhesive tape safely. The perforation of the lateral longitudinal portion of the adhesive tape may be formed from substantially round, square or oval openings, which are preferably arranged evenly distributed. This ensures that the adhesive function of the adhesive layer is impaired as little as possible and yet a penetration of a layer to be applied to the adhesive tape of a material through the openings can thereby adhere to the substrate to which the adhesive tape is adhered.

In einer vorteilhaften Ausführungsform der Erfindung weisen die Öffnungen des perforierten Längsabschnitts einen durchschnittlichen Durchmesser von mindestens 3 Millimeter auf.In an advantageous embodiment of the invention, the openings of the perforated longitudinal section have an average diameter of at least 3 millimeters.

Vorteilhaft sind die Öffnungen im wesentlichen rund, eckig oder oval.Advantageously, the openings are substantially round, angular or oval.

Nach einer vorteilhaften Ausgestaltung der Erfindung sind zwei seitliche Längsabschnitte vorgesehen, welche perforiert sind. Mit einem derartigen Klebeband können Fugen zwischen Bauteilen im Innenausbau abgedichtet werden, bei welchen beidseitig der Fuge das Klebeband mit einer Materialschicht anschließend überarbeitet wird. Dennoch ist unabhängig von der Dicke der auf das Klebeband aufzutragenden Putzschicht, die Dichtigkeit im Fugenbereich dadurch gewährleistet, dass in der Mitte das Klebeband nicht perforiert ist. Der nicht perforierte Abschnitt ist hierbei breiter als die maximale Breite der abzudichtenden Fugen.According to an advantageous embodiment of the invention, two lateral longitudinal sections are provided, which are perforated. With such an adhesive tape joints can be sealed between components in the interior, in which both sides of the joint, the tape is then reworked with a layer of material. Nevertheless, regardless of the thickness of the applied to the tape plaster layer, the tightness in the joint area is ensured by the fact that in the middle of the tape is not perforated. The non-perforated section is hereby wider than the maximum width of the joints to be sealed.

Nach einer weiteren vorteilhaften Ausgestaltung der Erfindung ist ein nicht klebender Mittelstreifen vorgesehen und der perforierte Längsabschnitt ist von dem Mittelstreifen beabstandet. Dies hat den Vorteil, dass das Band an Ecken oder Kanten ohne eine Verknittern glatt verklebt werden kann, da es der nicht klebende Mittelstreifen ermöglicht das Band in die Ecke zu drücken, ohne dass es sofort festklebt und sich Falten beim Verkleben bilden. Dadurch, dass der perforierte Längsabschnitt von dem Mittelstreifen beabstandet ist, wird verhindert, dass die Perforationsöffnungen zu Undichtigkeiten führen, wenn die abzudichtende Fuge mit dem nicht klebenden Mittelstreifen überdeckt wird.According to a further advantageous embodiment of the invention, a non-adhesive central strip is provided and the perforated longitudinal portion is spaced from the median strip. This has the advantage that the tape can be smoothly glued to corners or edges without wrinkling, as the non-adhesive center strip allows the tape to press into the corner without causing it immediately sticks and wrinkles form during gluing. The fact that the perforated longitudinal portion is spaced from the central strip, is prevented that the perforation openings lead to leaks when the joint to be sealed is covered with the non-adhesive central strip.

Nach einer weiteren vorteilhaften Ausgestaltung der Erfindung sind die Trägerschicht, die Klebeschicht und die abziehbare Deckfolie perforiert. Dies hat herstellungsbezogen den Vorteil, dass das Band in einfacher Weise hergestellt werden kann. Die Deckfolie verhindert dabei, dass ein Perforationswerkzeug, wie z.B. eine Stanzeinrichtung, mit der Klebeschicht des selbstklebenden Bandes in Berührung kommt.According to a further advantageous embodiment of the invention, the carrier layer, the adhesive layer and the peelable cover sheet are perforated. This production-related has the advantage that the tape can be produced in a simple manner. The cover sheet thereby prevents a perforating tool, such as e.g. a punching device, comes into contact with the adhesive layer of the self-adhesive tape.

Nach einer weiteren vorteilhaften Ausgestaltung der Erfindung besteht die Trägerschicht aus einem Material, welches eine gute Hafteigenschaft für Mauerputz aufweist. Derartige gute Hafteigenschaften sind beispielsweise durch ein offenporiges Material gewährleistet. Die Verbindung zwischen dem Mauerputz und der Trägerschicht und somit auch die Haftverbindung des Bandes an dem Untergrund wird hierdurch verbessert. Ein Ablösen oder Herausbrechen von Teilen des Mauerputzes wird sicher vermieden.According to a further advantageous embodiment of the invention, the carrier layer consists of a material which has a good adhesive property for plaster. Such good adhesive properties are ensured, for example, by an open-pored material. The connection between the plaster and the carrier layer and thus also the adhesive bond of the tape to the substrate is thereby improved. A detachment or breaking out of parts of the plaster is safely avoided.

Nach einer weiteren vorteilhaften Ausgestaltung der Erfindung weist die Deckfolie in Längsrichtung mindestens einen Schlitz auf, wobei das Band entlang des Schlitzes so auf sich selbst gefaltet sein kann, dass mindestens ein Teil der Deckfolie außen angeordnet ist. Hierdurch kann das Band auf einfache Weise auch in Kanten- und Eckbereichen verklebt werden, da zunächst ein Teil der Deckfolie abgezogen werden kann und dieser Teil des Bandes verklebt werden kann, ohne dass die Klebeschicht des anderen Teils des Bandes ständig ungeschützt ist und beispielsweise ungewollt an den Seiten angeklebt wird. Die Verarbeitung des Klebebandes wird auch an schwer zugänglichen oder verwinkelten Bereichen hierdurch vereinfacht. Dennoch ist mit dem erfindungsgemäßen Klebeband ein sicherer Halt dadurch gewährleistet, dass die Perforationsöffnungen ein teilweises Durchdringen des Bandes einer aufzutragenden Schicht, wie z.B. Putz erlauben, welche anschließend auf mindestens einen Teilbereich des Bandes aufgetragen wird.According to a further advantageous embodiment of the invention, the cover sheet has at least one slot in the longitudinal direction, wherein the tape along the slot can be folded onto itself so that at least a portion of the cover sheet is arranged outside. In this way, the tape can be glued easily in edge and corner areas, since first part of the cover sheet can be removed and this part of the tape can be glued without the adhesive layer of the other part of the tape is constantly unprotected and, for example, unintentionally glued to the sides. The processing of the adhesive tape is thereby simplified even in hard to reach or winding areas. Nevertheless, with the adhesive tape according to the invention a secure hold is ensured by the fact that the perforation openings a partial Penetrating the band of a layer to be applied, such as allow plaster, which is then applied to at least a portion of the band.

Eine weitere vorteilhafte Ausführungsform der Erfindung besteht darin, dass die Trägerschicht auf ihrer Oberseite einen Randklebeabschnitt aufweist, der mit einer abziehbaren Deckfolie versehen ist. Dies hat den Vorteil, dass ein Ankleben des Dichtungsbandes an einen Fensterrahmen oder Türrahmen vor deren Einbau in eine Maueröffnung möglich ist. Nach dem Einbau können dann die anderen Klebebereiche mit der Mauer verklebt werden und gegebenenfalls überputzt werden. Hierdurch sind auch spezielle Fugen mit besonderen Problemen wegen Eckbereichen udgl. mit dem Band luftdicht verschließbar.A further advantageous embodiment of the invention is that the carrier layer has on its upper side a Randklebeabschnitt, which is provided with a peelable cover sheet. This has the advantage that it is possible to stick the sealing strip to a window frame or door frame before it is installed in a wall opening. After installation, the other adhesive areas can then be glued to the wall and optionally plastered. This also special joints with special problems due to corners udgl. with the tape airtight sealable.

Alternativ kann die Deckfolie auch ungeschlitzt sein oder nur einen einzigen Schlitz 6 aufweisen. Die Trägerschicht 1 und die Klebeschicht 2 sind in einem Längsabschnitt 7 des Montageklebebandes perforiert, d.h. mit mehreren durchgehenden Öffnungen versehen. Die Perforation des Längsabschnittes 7 kann wie in dem gezeigten Ausführungsbeispiel aus runden Öffnungen 8 bestehen oder Öffnungen in einer eckigen, ovalen oder undefinierten Form aufweisen. Die Öffnungen der Perforation des Längsabschnittes 7 können gleichmäßig verteilt angeordnet sein oder in Richtung des seitlichen Randes des Montageklebebandes kleiner werden oder in ihrer Anzahl reduziert sein. Vorzugsweise sind die Perforationsöffnungen in dem Längsabschnitt 7 mit einem durchschnittlichen Durchmesser von mindestens 3 mm vorgesehen, damit ein ausreichendes Hindurchdringen von Putz, welcher nach dem Verarbeiten des Montageklebebandes auf die Trägerschicht aufgetragen wird, gewährleistet ist und der Putz eine zusätzliche Haltewirkung durch die Verbindung mit dem Untergrund bewirkt. Hiermit ist in dem Längsabschnitt 7 der Perforation zwar beim Ankleben des Montageklebebandes eine verminderte Klebewirkung aufgrund der Öffnungen der Perforation vorhanden, jedoch wird diese anschließend durch den aufzutragenden Mauerputz mehr als kompensiert. Es wird vorteilhafterweise vermieden, dass durch eine Schicht von Mauerputz oder dergleichen eine derartige Belastung auf die Trägerschicht des Klebebandes ausgeübt wird, dass das Klebeband Gefahr läuft, sich von dem Untergrund zu lösen und undicht zu werden.In FIG. 1 An assembly adhesive tape is shown, which has a carrier layer 1, an adhesive layer 2 and a cover film 3 provided on the adhesive layer 2. The cover sheet 3 is slit twice in this embodiment in the longitudinal direction of the tape, that is, it has two slots 6. Alternatively, the cover sheet may also be unslotted or have only a single slot 6. The carrier layer 1 and the adhesive layer 2 are perforated in a longitudinal portion 7 of the mounting tape, that is provided with a plurality of through openings. The perforation of the longitudinal section 7 may, as in the embodiment shown consist of round openings 8 or openings in an angular, oval or undefined shape. The openings of the perforation of the longitudinal section 7 may be arranged evenly distributed or be smaller in the direction of the lateral edge of the mounting tape or reduced in number. Preferably, the perforation openings are provided in the longitudinal section 7 with an average diameter of at least 3 mm, so as to ensure sufficient penetration of plaster, which is applied to the carrier layer after processing the mounting tape, and the plaster an additional holding effect by the connection with the Ground causes. This is in the longitudinal section 7 of the perforation while adhering the mounting tape, a reduced adhesive effect due to the openings of the perforation available, but this is then more than compensated by the applied wall plaster. It is advantageously avoided that such a load is exerted on the carrier layer of the adhesive tape by a layer of plaster or the like that the adhesive tape runs the risk of becoming detached from the substrate and becoming leaky.

In Figur 2 ist das Montageklebeband aus Figur 1 dargestellt, wobei hier ein Teil des Klebebandes auf sich selbst gefaltet ist. Es entsteht somit ein vorgefaltetes Montageklebeband, welches an dem Schlitz 6 der Deckfolie 3 so vorgefaltet ist, dass zunächst ein Teil der Deckfolie 3 abgezogen werden kann und beispielsweise leicht in einem Kanten- oder Eckbereich angeklebt werden kann, bevor der andere Teil der Deckfolie 3 (in Figur 2 auf der nicht dargestellten Rückseite des Klebebandes) abgezogen und verklebt werden kann. Die Öffnungen 8 des perforierten Längsabschnittes 7 des Klebebandes sind bei diesem Ausführungsbeispiel gleichmäßig verteilte runde Öffnungen 8, sie können jedoch auch eine andere Form aufweisen bzw. ungleichmäßig über den Längsabschnitt 7 verteilt angeordnet sein.In FIG. 2 is the mounting tape off FIG. 1 represented here, wherein here a part of the adhesive tape is folded on itself. Thus, a prefolded assembly adhesive tape is produced, which is prefolded on the slot 6 of the cover film 3 such that first part of the cover film 3 can be pulled off and, for example, easily glued in an edge or corner area, before the other part of the cover film 3 (FIG. in FIG. 2 on the non-illustrated back of the tape) can be removed and glued. The openings 8 of the perforated longitudinal section 7 of the adhesive tape are uniformly distributed round openings 8 in this embodiment, but they can also have a different one Have shape or arranged unevenly distributed over the longitudinal section 7.

Figur 3 zeigt ein weiteres Ausführungsbeispiel der Erfindung, wobei die Trägerschicht auf ihrer Oberseite einen Randklebeabschnitt 9 aufweist, der mit einer abziehbaren Deckfolie 10 versehen ist. In der Figur 3 sieht man aufgrund des gewählten Blickwinkels das erfindungsgemäße Selbstklebeband von seiner "Unterseite" her. Die Abbildung des Montageklebebandes der Figur 3 entspricht ansonsten der des Montageklebebandes gemäß Figur 1, wobei gleiche Bezugszeichen gleiche Merkmale bezeichnen. FIG. 3 shows a further embodiment of the invention, wherein the carrier layer has on its upper side a Randklebeabschnitt 9, which is provided with a peelable cover sheet 10. In the FIG. 3 Due to the selected viewing angle, the self-adhesive tape according to the invention can be seen from its "underside". The picture of mounting tape the FIG. 3 otherwise corresponds to that of the mounting tape according to FIG. 1 , wherein like reference numerals designate like features.
