Abstract

In double-sided pressure-sensitive adhesive material with a film base, the film contains microballoons (I).

Description

1. Die Erfindung betrifft ein doppelseitig haftklebend aus­ gerüstetes Haftklebematerial mit einem Träger auf Filmba­ sis.1. The invention relates to a double-sided pressure-sensitive adhesive scaffolded PSA material with a support on film base sis.

Zur dauerhaften Verklebung beispielsweise von Spiegeln auf Schränken in der Möbelindustrie werden bislang doppelseitig haftklebend ausgerüstete Haftklebematerialien mit Trägern auf Schaumstoffbasis eingesetzt, die aufgrund des oftmals hohen Gewichtes der Spiegel besonders scherfest sein müs­ sen, damit auch geringfügiges Rutschen des angeklebten Spiegels verhindert wird. Desweiteren muß der Träger eines solchen Haftklebematerials in der Lage sein, auftretende Unebenheiten auf der Substratseite zu kompensieren, damit es aufgrund schlechter Verklebung nicht zu einem Abrutschen des angebrachten Spiegels kommt.For permanent bonding of mirrors, for example Cabinets in the furniture industry are currently double-sided Pressure-sensitive adhesive pressure-sensitive adhesive materials with carriers used on foam basis, due to the often high weight of the mirror must be particularly shear resistant sen, so that even slight gliding of the glued Mirror is prevented. Furthermore, the carrier of a such pressure-sensitive adhesive material to be able to occur To compensate for unevenness on the substrate side, so it does not slip due to poor adhesion the attached mirror comes.

Derartige Anforderungen weisen bislang Haftklebematerialien mit Schaumstoffträgern auf Basis von Polyethylen, Polyuret­ han oder Polyacrylat auf. Als Haftklebstoffe kommen solche auf Basis von Acrylat-, Silikon-, Polyurethan- oder Kautschukklebern zum Einsatz. Die so aufgebauten Haftklebe­ materialien verfügen über eine ausreichende Dicke und Kom­ pressibilität, um eventuell auftretende Unebenheiten zu kompensieren. Nachteilig erweist sich jedoch die zu geringe Scherbelastbarkeit des Schaumträgers, was bei hoher Bela­ stung zu Problemen führt.Such requirements have hitherto been pressure-sensitive adhesive materials with foam carriers based on polyethylene, Polyuret han or polyacrylate. As pressure-sensitive adhesives come such based on acrylate, silicone, polyurethane or Rubber adhesives used. The adhesive thus constructed Materials have sufficient thickness and grain pressibility to prevent any unevenness compensate. The disadvantage, however, proves to be too low Shear resilience of the foam carrier, which at high Bela equipment leads to problems.

Aufgabe der Erfindung ist es daher, die Scherbelastbarkeit des Trägersystems der nach dem heutigen Stand der Technik hergestellten Haftklebematerialien zu verbessern.The object of the invention is, therefore, the shear capacity the carrier system of the state of the art improved pressure-sensitive adhesive materials.

Gelöst wird diese Aufgabe überraschenderweise durch ein doppelseitig haftklebend ausgerüstetes Haftklebematerial mit einem Träger auf Filmbasis, der Mikrohohlkugeln ent­ hält.This problem is solved surprisingly by a Pressure-sensitive adhesive material with double-sided pressure-sensitive adhesive properties  with a film-based carrier ent the hollow microspheres ent holds.

Besonders geeignet sind Filme auf Polyurethanbasis. Die Mikrohohlkugeln enthalten vorzugsweise organische Materia­ lien. Der max. Durchmesser der Mikrokugeln liegt bei 5 bis 350 µm, vorzugsweise bei 10 bis 150 µm. Der Anteil der Mi­ krokugeln in den Filmen beträgt bis zu 50 Vol.-%. Als be­ sonders geeignet haben sich Mikrokugeln auf Polymerbasis erwiesen.Particularly suitable are polyurethane-based films. The Hollow microspheres preferably contain organic matter lien. The max. Diameter of the microspheres is 5 to 350 μm, preferably at 10 to 150 μm. The share of Mi Crocs in the films is up to 50 vol .-%. As be especially suitable are microspheres based on polymers proved.

Der zur ein- oder beidseitigen Ausrüstung des Trägermateri­ als einzusetzende Haftkleber kann aus der Gruppe der Acry­ lat-, Silikon-, Polyurethan- oder Kautschukkleber ausge­ wählt werden. Die haftklebenden Flächen können vor Gebrauch durch Abdeckungen geschützt werden. Das Haftklebematerial kann noch weitere Schichten umfassen, wie z. B. solche zum Dickenausgleich oder zur Wärmeaktivierbarkeit. Besondere Bedeutung haben erfindungsgemäße Haftklebemate­ rialien in der Möbelindustrie. Hier werden sie beispiels­ weise in Form von Bändern zur Befestigung von Spiegeln auf Schränken eingesetzt. Die dabei an das Haftklebematerial zu stellenden Anforderungen bezüglich der Scherbelastbarkeit werden von der herkömmlichen Materialien nicht erfüllt. Aufgrund des Schaumstoffträgers ist die Scherbelastbarkeit dieser Materialien nicht ausreichend so hoch und es kommt zu einem Versatz infolge Abrutschens des aufgeklebten Spie­ gels.The one- or two-sided equipment of the Trägermateri as to be used pressure-sensitive adhesive can from the group of Acry lat, silicone, polyurethane or rubber adhesive out be chosen. The pressure-sensitive adhesive surfaces can be used before use protected by covers. The pressure-sensitive adhesive material may include other layers, such as. B. such Thickness compensation or for heat activation. Particular importance is attached to pressure-sensitive adhesives according to the invention rials in the furniture industry. Here you will for example wise in the form of bands for attaching mirrors Cabinets used. The case of the pressure-sensitive adhesive material requirements with regard to shear resilience are not fulfilled by the conventional materials. Due to the foam carrier is the shear load capacity these materials are not high enough and it comes to an offset due to slipping of the glued Spie gels.

Mit dem Haftklebematerial nach der Erfindung wird dieser Nachteil behoben. Durch den Einsatz eines Trägers auf Film­ basis, der Mikrohohlkugeln enthält, wird das Haftklebemate­ rial wesentlich stabiler und es kommt zu keinem Verrutschen des Spiegels. With the pressure-sensitive adhesive material according to the invention this becomes Disadvantage solved. By using a carrier on film base, which contains hollow microspheres, becomes the pressure-sensitive adhesive rial much more stable and there is no slippage of the mirror.
