Description

Die Erfindung bezieht sich auf einen Verbundwerkstoff für Lampenschirme mit den Merkmalen nach dem Oberbegriff des Anspruchs 1.The invention relates to a composite material for lampshades with the features according to Preamble of claim 1.

Für Lampenschirme mit dem angestrebten Aussehen von PVC-Folie werden neben zahlreichen natürlichen Produkten auch PVC- haltige Verbundwerkstoffe oder PVC-Folien eingesetzt.For lampshades with the desired appearance of PVC film, in addition to numerous natural products, PVC containing composite materials or PVC films.

Aus CH-492 927 ist ein Lampenschirm bekannt, der aus einer mit einem Karton heißversiegelten Kunststoffolie besteht.From CH-492 927 a lampshade is known which consists of one with a box heat-sealed plastic film.

DE-GM 19 49 704 richtet sich auf einen Lampenschirmkarton, dessen Karton mit einem thermoplastischen Kunstharz imprägniert ist und auf dessen Oberfläche ein- oder beidseitig aus der Schmelze eine Polyäthylenschicht aufkaschiert ist.DE-GM 19 49 704 is directed to a lampshade box, the box with is impregnated with a thermoplastic synthetic resin and or a polyethylene layer is laminated on both sides from the melt.

EP-A-344 589 richtet sich auf die Verwendung von wasserlöslichen Polymerisaten, die durch Lösungspolymerisation von Acrylsäure, Methacrylsäure, Hydroxy­ ethylacrylat, Hydroxypropylacrylat mit copolymerisierbaren monoethylenisch ungesättigten Monomeren hergestellt sind als Kaschierkleber, der den Verbundmaterialien eine hohe Sperrwirkung gegen den Durchgang von Gasen verleiht. Der Kleber haftet gut auf Kunststoffolien wie orientierten Polyethylen- oder Polypropylenfolien.EP-A-344 589 is directed to the use of water-soluble polymers, by the solution polymerization of acrylic acid, methacrylic acid, hydroxy ethyl acrylate, hydroxypropyl acrylate with copolymerizable monoethylenic Unsaturated monomers are produced as laminating glue, which the Composite materials have a high barrier effect against the passage of gases gives. The adhesive adheres well to plastic films such as oriented polyethylene or Polypropylene films.

Die grundsätzlich bekannte Verwendung von Polyvinylchlorid als Lampen­ schirmmaterial ist jedoch aus Gründen des Umweltschutzes häufig unerwünscht.The basically known use of polyvinyl chloride as lamps Screen material is often undesirable for environmental reasons.

Aufgabe der vorliegenden Erfindung ist es, einen Verbundwerkstoff für Lampenschirme mit dem Aussehen einer PVC-Folie zu schaffen, das jedoch kein Polyvinylchlorid enthält.The object of the present invention is to provide a composite material for To create lampshades with the appearance of a PVC film, but not Contains polyvinyl chloride.

Diese Aufgabe wird gelöst durch einen Verbundwerkstoff für Lampenschirme gemäß den im kennzeichnenden Teil des Patentanspruchs 1 angegebenen Merkmalen.This object is achieved by a composite material for lampshades according to the features specified in the characterizing part of patent claim 1.

Völlig überraschend wurde gefunden, daß sich durch Verwendung einer einseitig matten Polyolefinfolie, deren Rauhtiefe der matten Oberfläche 2-5 µm beträgt, in Verbindung mit einem Karton einer Dicke von 50 µm bis 320 µm ein Material herstellen läßt, das im Aussehen mit den bisher verwendeten Lampenschirm­ materialien aus Polyvinylchlorid übereinstimmt.Completely surprisingly, it was found that using one sided matt polyolefin film, the roughness of the matt surface is 2-5 µm, in Connection with a cardboard with a thickness of 50 µm to 320 µm a material can produce that in appearance with the lampshade previously used materials made of polyvinyl chloride.

Vorzugsweise werden zum Kaschieren Polypropylenfolien oder Polyethylenfolien mit einer Dicke von 5 bis 40 µm verwendet, ganz besonders bevorzugt 10-20 µm. Polypropylene films or polyethylene films are preferably used for lamination a thickness of 5 to 40 microns used, most preferably 10-20 microns.  

Als Trägermaterial dient ein opaker Karton mit Flächengewichten von 50 bis 300 g/m², vorzugsweise 100-280 g/m². Das Kartonträgermaterial kann neben einem opazifizierenden Füllstoff auch noch Farbpigmente enthalten oder anderweitig eingefärbt sein. Die Dicke des als Trägermaterial verwendeten Kartons beträgt zwischen 50 und 320 µm.An opaque cardboard with basis weights of 50 to 300 serves as the carrier material g / m², preferably 100-280 g / m². The cardboard backing material can be next to one opacifying filler also contain color pigments or otherwise be colored. The thickness of the cardboard used as the carrier material is between 50 and 320 µm.

Die Polyolefinfolie weist auf der matten Seite eine Rauhtiefe von 2-5 µm (Rz-Wert) auf. Die Messung erfolgt nach DIN 4768.The polyolefin film has a surface roughness of 2-5 µm (R z value) on the matt side. The measurement is carried out according to DIN 4768.

Der Verbundwerkstoff hat eine Steifigkeit, die der Steifigkeit üblicher Polyvinylchloridfolien für Lampenschirme entspricht.The composite has a stiffness that is more common than stiffness Corresponds to polyvinyl chloride films for lampshades.

Die Steifigkeit wird gemessen nach DIN 52 121 und beträgt von 500 bis 4000 cN/28 mm. Durch die matte Oberfläche der Polyolefinfolie wird der optische Eindruck und der Griff eines üblichen PVC-Lampenschirmmaterials erweckt, ohne daß das Material Polyvinylchlorid enthält.The stiffness is measured according to DIN 52 121 and is from 500 to 4000 cN / 28 mm. Due to the matt surface of the polyolefin film, the visual impression and the handle of a common PVC lampshade material awakens without that Material contains polyvinyl chloride.

Der Verbund zwischen dem Trägerkarton und der Polyolefinfolie wird durch Verwendung eines sogenannten Kaschierklebestoffes, der am Karton und an der glatten Seite der Polyolefinfolie haftet, hergestellt. Hierbei können handelsübliche 1- bzw. 2-Komponenten-Polyurethan-Kleber Polyacrylatkleber und PVA-Kleber auf Lösemittel- oder Dispersionsbasis verwendet werden. Um eine ausreichend Haftung der Schichten des Verbundes zu erreichen, können je nach Klebersystem und Auftragsverfahren 2 g/m² bis 20 g/m² Kaschierkleber verwendet werden.The bond between the carrier board and the polyolefin film is through Use of a so-called laminating adhesive, which is on the box and on the smooth side of the polyolefin film adheres. Commercial 1- or 2-component polyurethane adhesive, polyacrylate adhesive and PVA adhesive Solvent or dispersion base can be used. To ensure adequate liability The layers of the composite can be reached depending on the adhesive system and Application method 2 g / m² to 20 g / m² laminating adhesive can be used.

Der Verbundwerkstoff wird wie folgend hergestellt:
Für die einseitige Kaschierung wird die glatte Seite der Polyolefinfolie mit einem 2K- Polyurethan-Dispersionskleber mit einem Trockenauftrag von vorzugsweise 2-3 g/m² beschichtet, getrocknet und der Karton zukaschiert. The composite is made as follows:
For one-sided lamination, the smooth side of the polyolefin film is coated with a 2-component polyurethane dispersion adhesive with a dry application of preferably 2-3 g / m², dried and the cardboard is laminated on.

Die beidseitige Kaschierung des Kartons kann durch eine zweimalige Durchführung des oben beschriebenen Arbeitsganges oder bei entsprechender Maschinen­ technologie auch in einem Arbeitsgang durchgeführt werden.The double-sided lamination of the cardboard can be carried out twice the operation described above or with appropriate machines technology can also be carried out in one operation.

Ebenso kann der Verbundwerkstoff durch Beschichtung des Kartons mit einem geeigneten Kleber und Zukaschierung der Folie hergestellt werden. Erfahrungsgemäß sind hier allerdings höhere Kleberaufträge (5-10 g/m² Trocken­ auftrag) für eine ausreichende Verbundhaftung notwendig.The composite material can also be coated with a cardboard suitable adhesive and laminating the film. Experience has shown, however, that there are higher adhesive layers (5-10 g / m² dry order) is necessary for sufficient bond liability.
