Description

Die vorliegende Erfindung betrifft ein Trennband und ein Verfahren zur Montage des Trennbands im Trockenbau.The present invention relates to a separating tape and a method for assembling the separating tape in drywall.

Im Trockenbau ist es notwendig in verschiedenen Situationen eine Trennfuge vorzusehen.In dry construction it is necessary to provide a parting line in various situations.

Beispielsweise ist es beim Anschluss von flächigen Trockenbauplatten (Trockenbauflächen) an massive Bauteile notwendig, eine Trennfuge vorzusehen, um wegen der unterschiedlichen Ausdehnung bzw. hygrothermischen Ausdehnungskoeffizienten der Materialien (Trockenbaufläche und massives Bauteil) unter der Einwirkung von Feuchte und Temperatur eine unregelmäßige ("Zick-Zack") Rissbildung am Übergang unter der Einwirkung von Temperatur, Feuchtigkeit oder Erschütterung zu verhindern.For example, when connecting flat drywall panels (drywall surfaces) to solid components, it is necessary to provide a separating joint in order to create an irregular ("zigzag- Zack ") to prevent cracking at the transition under the influence of temperature, moisture or vibration.

Auch beim Verputzen von aneinanderstoßenden, aus unterschiedlichen Materialien bestehenden Bauteilen, z.B. Trockenbauflächen und massiven Bauteilen, ist es sinnvoll, den Putzbereich im Bereich des Bauteilanschlusses mit einer Fuge zu trennen, um unregelmäßige Risse im Putz an der Nahtstelle möglichst zu vermeiden.Even when plastering adjoining components made of different materials, e.g. dry construction surfaces and solid components, it makes sense to separate the plaster area in the area of the component connection with a joint in order to avoid irregular cracks in the plaster at the seam as far as possible.

Trennbänder werden verwendet, um bei der hygrothermischen Bewegung oder bei Bewegungen aufgrund von Erschütterungen zweier Bauteile relativ zueinander eine Haarfuge (ähnlich einer Schattennut) auszubilden. Dadurch wird eine Zick-Zack Rissbildung verhindert und man erhält einen optisch einheitlichen Eindruck.Separating tapes are used to create a hairline joint (similar to a shadow groove) during hygrothermal movement or when moving due to vibrations between two components. This prevents the formation of zigzag cracks and gives a visually uniform impression.

Hierzu wird im Stand der Technik ein streifenförmiges Trennband aus Papier verwendet, das typischerweise etwa 50 bis 70 mm breit ist und auf der Vorderseite in Laufrichtung einseitig einen fast am Rand befindlichen, typischerweise etwa 10 bis 15 mm breiten, selbstklebenden Klebestreifen aufweist.For this purpose, a strip-shaped separating tape made of paper is used in the prior art, which is typically about 50 to 70 mm wide and has a self-adhesive strip on one side on the front side in the running direction, typically about 10 to 15 mm wide, almost at the edge.

Das Trennband wird üblicherweise auf das massive Bauteil direkt anschließend an das montierte Profil, das die Trockenbaufläche trägt, aufgeklebt. Dabei wird das Trennband entlang des Profils so aufgeklebt, dass ein selbstklebender Klebestreifen des Trennbands an das Profil anstößt und von der später fast anstoßenden Trockenbauplatte verdeckt wird.The separating tape is usually glued onto the solid component directly after the mounted profile that carries the dry construction surface. The separating tape is glued along the profile in such a way that a self-adhesive The adhesive strip of the separating tape touches the profile and is covered by the drywall that later almost touches it.

Weniger üblich ist es, das Trennband vor der Montage des Profils auf das massive Bauteil so auf das Profil zu kleben, dass der nichtklebende Teil über die Fläche des Profils und nach der Montage des Profils über die Kontaktfläche von massivem Bauteil und Profil sowie massivem Bauteil und fast anstoßender Trockenbauplatte übersteht.It is less common to stick the separating tape to the profile before mounting the profile on the solid component so that the non-adhesive part is over the surface of the profile and after mounting the profile over the contact surface of the solid component and profile as well as the solid component and almost abutted drywall.

Die Trockenbauplatte wird dann mit einem Abstand von typischerweise etwa 3 bis 5 mm zum Trennband auf das Profil montiert und der Abstand zwischen Trockenbauplatte und Trennband mit Spachtelmasse ausgefugt.The drywall is then mounted on the profile with a distance of typically about 3 to 5 mm from the separating tape and the distance between the drywall and separating tape is grouted with filler.

Der nichtklebende Teil des Trennbands steht dabei über die Fuge hinaus. Nach dem Trocknen wird die Spachtelmasse gegebenenfalls geschliffen und der überstehende, nichtklebende Papierstreifen mit einem spitzen Gegenstand, z.B. einem Messer, abgetrennt.The non-adhesive part of the separating tape protrudes over the joint. After drying, the filler is sanded if necessary and the protruding, non-adhesive paper strip is cut off with a sharp object, e.g. a knife.

Es zeigt sich, dass sich der nichtklebende Teil des Trennbands unter ändernden Umgebungsbedingungen (Luftfeuchtigkeit oder Temperatur) ausdehnt oder zusammenzieht. Dabei kann sich das Papier aufrollen, wobei sich das Trennband vom massiven Bauteil wegbiegt.It can be seen that the non-adhesive part of the release tape expands or contracts under changing environmental conditions (humidity or temperature). The paper can roll up, causing the separating tape to bend away from the solid component.

Wenn sich das Trennband aufbiegt, kann die Spachtelfuge nicht vollständig bzw. nicht sauber genug mit Spachtelmasse gefüllt werden. Dies erschwert den exakten Anschluss und die planebene Verspachtelung und führt auch zu keinem Abriss des Trennbands entlang der Kante zwischen massivem Bauteil und Trockenbaufläche. Es verbleibt dann ein optisch unbefriedigender Eindruck.If the separating tape bends open, the filler joint cannot be filled completely or not cleanly enough with filler. This complicates the exact connection and the level filling and also does not lead to the separation tape being torn off along the edge between the solid component and the drywall surface. An optically unsatisfactory impression then remains.

Es kann grundsätzlich auch Spachtelmasse unter das Trennband gelangen und das Abtrennen des überstehenden Papierstreifens erschweren.In principle, filler can also get under the separating tape and make it difficult to separate the protruding paper strip.

Aufgabe der vorliegenden Erfindung ist es, ein Trennband und ein Verfahren zur Montage des Trennbands bereitzustellen, welche die Probleme des Standes der Technik zumindest teilweise lösen, insbesondere das Aufbiegen des Trennbands zu reduzieren.The object of the present invention is to provide a separating tape and a method for assembling the separating tape which at least partially solve the problems of the prior art, in particular to reduce the bending open of the separating tape.

Gelöst wird die Aufgabe durch ein Trennband für einen Trockenbauwandanschluss mit zwei Hauptflächen eines Trägermaterials und Klebstoff, wobei eine erste Hauptfläche längs einer Achse in Bahnrichtung in mindestens zwei Bereiche unterteilt ist, wobei die mindestens zwei Bereiche zumindest teilweise mit Klebstoff beschichtet sind und die mindestens zwei Bereiche eine voneinander abweichende Klebkraft aufweisen, wobei das Trägermaterial Papier ist.The object is achieved by a separating tape for a drywall connection with two main surfaces of a carrier material and adhesive, a first main surface being divided into at least two areas along an axis in the direction of the web, the at least two areas being at least partially coated with adhesive and the at least two areas have a different bond strength, the carrier material being paper.

Erfindungsgemäß hat das Trennband zwei Hauptflächen, die sich auf den gegenüberliegenden Seiten des Trennbandes befinden. Eine der Hauptflächen ist längs einer Achse in Bahnrichtung unterteilt. Diese Bereiche sind zumindest teilweise mit einem Klebstoff beschichtet, weisen jedoch eine voneinander abweichende Klebkraft auf. Typischerweise erstrecken sich diese Bereiche über die gesamte Länge des Trennbandes.According to the invention, the separating tape has two main surfaces which are located on opposite sides of the separating tape. One of the main surfaces is divided along an axis in the path direction. These areas are at least partially coated with an adhesive, but have different adhesive strengths. Typically these areas extend over the entire length of the separating tape.

In einer anderen Ausführungsform wird die Aufgabe gelöst durch ein Trennband für einen Trockenbauwandanschluss mit zwei Hauptflächen, wobei eine erste Hauptfläche längs einer Achse in Bahnrichtung in mindestens zwei Bereiche unterteilt ist, wobei mindestens ein Bereich mit Klebstoff beschichtet ist, wobei das Trägermaterial ausgewählt wird aus beidseitig gestrichenem oder beschichtetem Papier oder Vliesen mit Kunstfaseranteilen.In another embodiment, the object is achieved by a separating tape for a drywall connection with two main surfaces, a first main surface being divided into at least two areas along an axis in the direction of the web, with at least one area being coated with adhesive, the carrier material being selected from on both sides Coated or coated paper or nonwovens with synthetic fibers.

Beidseitig gestrichene oder beschichtete Papiere oder Vliese mit Kunstfaseranteilen sind weniger feuchtigkeitsempfindlich als zumindest einseitig offene Papiere. Bevorzugt werden Trägerbahn-Materialien eingesetzt, die bei Lagerung in einem Proberaum mit 100% Luftfeuchtigkeit im Zeitraum von 30 min weniger als 2 g Wasser/m2 aufnehmen können.Papers or nonwovens with synthetic fibers that are coated or coated on both sides are less sensitive to moisture than papers that are open at least on one side. Carrier web materials are preferably used which, when stored in a sample room with 100% air humidity, can absorb less than 2 g of water / m 2 over a period of 30 minutes.

Streichen und Beschichten sind Tätigkeiten in der Papierherstellung, um Eigenschaften von Papieren zu verändern. Durch das Streichen wird ein Bindemittel ein- oder mehrfach aufgetragen und das Papier gegebenenfalls anschließend kalandriert. Beispiele für beschichtete Papiere sind solche, die polyethylenbeschichtet sind. Es ist auch möglich, dass eine Seite des Papiers gestrichen und die andere beschichtet ist.Painting and coating are activities in paper manufacture in order to change the properties of paper. Painting becomes a binding agent applied one or more times and then calendered the paper if necessary. Examples of coated papers are those that are polyethylene coated. It is also possible that one side of the paper is coated and the other is coated.

Als Dicke der Trägerbahn haben sich Dicken im Bereich von 12 µm bis 100 µm bewährt.Thicknesses in the range from 12 µm to 100 µm have proven useful as the thickness of the carrier web.

Bevorzugt wird als Klebstoff ein drucksensitiver Kleber eingesetzt. Hierzu können wässrig dispergierte oder in organischen Lösungsmitteln gelöste Haftklebstoffe, beispielsweise auf Acrylat- oder Kautschuk-Basis, oder Haftschmelzklebstoffe auf Kautschuk- oder Acrylat-Basis zum Einsatz kommen. Grundsätzlich kann es sich bei den Klebstoffen auch um reaktive Klebstoffe handeln, die thermisch, d.h. durch Wärme oder IR-Strahlung, oder durch UV-oder Elektronenstrahlung weitervernetzt werden.A pressure-sensitive adhesive is preferably used as the adhesive. For this purpose, pressure sensitive adhesives dispersed in water or dissolved in organic solvents, for example based on acrylate or rubber, or hot melt pressure sensitive adhesives based on rubber or acrylate can be used. In principle, the adhesives can also be reactive adhesives that are further crosslinked thermally, i.e. by heat or IR radiation, or by UV or electron radiation.

Es ist grundsätzlich bevorzugt, dass zusätzlich ein klebstofffreier Bereich vorhanden ist, der es insbesondere erlaubt, das Trennband im Randbereich von einer Oberfläche leichter zu entfernen. Der klebstofffreie Bereich liegt daher insbesondere am Randbereich des Trennbandes neben den mit Klebstoff beschichteten Bereichen auf der gleichen Hauptfläche.It is fundamentally preferred that there is also an adhesive-free area which, in particular, allows the separating tape to be removed more easily from a surface in the edge area. The adhesive-free area therefore lies in particular at the edge area of the separating tape next to the areas coated with adhesive on the same main surface.

Beispielsweise können die Bereiche mit voneinander abweichenden Klebkräften ausgeführt werden, indem zwei unterschiedliche Klebstoffe eingesetzt werden, die eine unterschiedliche Klebkraft aufweisen. Es ist auch möglich, den gleichen Klebstoff, aber in unterschiedlichen Mengen (Flächengewichten) aufzutragen.For example, the areas can be designed with adhesive strengths that differ from one another by using two different adhesives which have different adhesive strengths. It is also possible to apply the same adhesive, but in different quantities (basis weights).

Es ist auch möglich, dass die gleiche Menge Klebstoff aufgebracht wird, aber der Klebstoff in einem Bereich abgestumpft wird.It is also possible for the same amount of glue to be applied but the glue to become blunted in one area.

In einer bevorzugten Ausführungsform wird der gleiche Klebstoff verwendet, aber der Klebstoff wird in gerasterter Form, z.B. in Punkten, auf die unterschiedlichen Bereiche aufgebracht, wobei die entsprechenden Rasterformen unterschiedliche Formen, Größen oder Abstände aufweisen, um dadurch die Klebeflächen und ihre Klebkräfte zu steuern. Die Herstellung von solchen gerasterten, z.B. punktförmigen Klebeflächen kann bevorzugt im Siebdruck erfolgen. Klebstoff-Flächengewichte im stark klebenden Bereich von etwa 20 bis 50 g/m2 und im schwach klebenden Bereich von 0,5 bis 5 g/m2 haben sich als geeignet erwiesen. Die Klebkraft sollte so eingestellt werden, dass sich der schwach haftende Bereich leicht und rückstandsfrei wieder ablösen lässt; der andere soll grundsätzlich fest haften. Für den Fall, dass eine Repositionierung des gesamten Trennband erforderlich ist, sollte die Klebkraft des fest haftenden Bereichs nicht zu groß sein.In a preferred embodiment, the same adhesive is used, but the adhesive is applied in grid form, for example in dots, to the different areas, the corresponding grid forms having different shapes, sizes or spacings in order to achieve the To control adhesive surfaces and their adhesive strength. The production of such screened, for example point-shaped, adhesive surfaces can preferably be carried out by screen printing. Adhesive weights per unit area in the strongly adhesive range from about 20 to 50 g / m 2 and in the weakly adhesive range from 0.5 to 5 g / m 2 have proven to be suitable. The bond strength should be adjusted so that the weakly adhering area can be easily removed again without leaving any residue; the other should basically stick firmly. In the event that the entire release tape needs to be repositioned, the adhesive strength of the firmly adhering area should not be too great.

Typische Klebkräfte (gemessen nach der FINAT Testmethode Nr. 2, FTM2, 20 min, Klebung auf Glas) sind 5 bis 20 N/25 mm für den fest haftenden Bereich und 0,5 bis 2 N/25 mm für den schwach haftenden und wiederabzulösenden Bereich.Typical bond strengths (measured according to FINAT test method No. 2, FTM2, 20 min, bonded to glass) are 5 to 20 N / 25 mm for the firmly adhering area and 0.5 to 2 N / 25 mm for the weakly adhering area that needs to be removed again Area.

In einer bevorzugten Ausführungsform ist die Trägerbahn auf der Seite, die keinen Kleber aufweist, silikonisiert. Wenn das Trennband aufgerollt wird, wirkt die silikonisierte Seite als Trennschicht auf den Kleber, so dass keine separate Abdeckbahn vorgesehen werden muss.In a preferred embodiment, the carrier web is siliconized on the side that has no adhesive. When the release tape is rolled up, the siliconized side acts as a release layer on the adhesive, so that no separate cover sheet has to be provided.

Die Variante, in der mindestens zwei Klebstoffbereiche vorhanden sind, hat den Vorteil, dass das einzusetzende Material Papier sein kann, das leicht entsorgt werden kann und natürlich nachwächst, Dabei kann das Trägermaterial aus unter Feuchte dehnfähigem Papier, z.B. zumindest einseitig offenem Papier, oder Vlies, z.B. reinem Cellulose-Vlies bestehen. Vliese mit Kunstfaseranteilen oder Kunststofffolien sind unter Umweltgesichtspunkten nachteilig.The variant in which there are at least two adhesive areas has the advantage that the material to be used can be paper, which can be easily disposed of and naturally grows again , for example, consist of pure cellulose fleece. Nonwovens with synthetic fibers or plastic films are disadvantageous from an environmental point of view.

Ausführungsformen, in denen das Trägermaterial auf Papier beruht, sind daher besonders bevorzugt.Embodiments in which the carrier material is based on paper are therefore particularly preferred.

Die Figuren 1 bis 5 zeigen eine Hauptfläche des Trennbandes mit klebstofffreien Bereichen (1) und Bereichen mit niedrigerer (2) bzw. höherer Klebkraft (3).the Figures 1 to 5 show a main surface of the release tape with adhesive-free areas (1) and areas with lower (2) or higher adhesive strength (3).
