Description

Dekorative Schichtpreßstoffplatte und Verfahren zu deren Herstellung Decorative laminated sheet and process for its manufacture
Die Erfindung bezieht sich auf eine dekorative Schichtpreßstoffplatte gemäß dem Oberbegriff des Patentanspruches 1, sowie auf ein Verfahren zur Herstellung einer solchen Schichtpreßstoffplatte.The invention relates to a decorative laminate according to the preamble of claim 1, and to a method for producing such a laminate.
Solche Schichtpreßstoffplatten finden bei der Herstellung von Möbeln sowie dem Ausbau von Gebäuden eine bevorzugte Anwendung. Zur Ausbildung dieser dekorativen Schichtpreßstoffplatten wird ein Kern aus harzgetränkten Natronkraftpapierbahnen gebildet, die zu einem Stapel aufeinandergelegt werden. Zur Bildung einer dekorativen Oberfläche wird wenigstens eine mit einem Kunstharz getränkte Papierbahn als oberste auf diesen Stapel aufgelegt, die eingefärbt oder bedruckt ist. Anschließend wird der so gebildete Stapel bei einer vorgebbaren Temperatur und einem entsprechenden Druck verpreßt.Laminates of this type are preferred in the manufacture of furniture and the expansion of buildings. To form these decorative laminated sheets, a core of resin-impregnated sodium kraft paper webs is formed, which are placed on top of one another in a stack. To form a decorative surface, at least one paper web impregnated with a synthetic resin is placed on top of this stack as the top one, which is colored or printed. The stack thus formed is then pressed at a predeterminable temperature and a corresponding pressure.
Mit Hilfe dieser dekorativen Schichtpreßstoffplatten werden Verbundelemente hergestellt, die zur Möbelfertigung benutzt werden. Zur Ausbildung solcher Verbundelemente wird auf die Oberfläche eines Trägers eine solche dekorative Schichtpreßstoffplatte aufgeleimt. Als Träger werden vorzugsweise Spanplatten verwendet. Es besteht auch die Möglichkeit Träger zu verwenden, die aus einem anorganischen Material, wie z.B. Beton, Zement, Gips oder Ton gefertigt sind. Um den dekorativen Schichtpreßstoffplatten bzw. den später damit hergestellten Verbundelementen ein ansprechendes Aussehen zu verleihen, sind die Oberflächen dieser dekorativen Schichtpreßstoffplatten je nach Bedarf als Glanz- oder Spezialmattfläche ausgebildet.With the help of these decorative laminated panels, composite elements are produced that are used for furniture production. To form such composite elements, such a decorative laminate is glued onto the surface of a carrier. Chipboard is preferably used as the carrier. It exists also the possibility to use beams made of an inorganic material such as concrete, cement, plaster or clay. In order to give the decorative laminated panels or the composite elements subsequently produced with them an attractive appearance, the surfaces of these decorative laminated panels are designed as glossy or special matt surfaces, as required.
Da für die Herstellung von Verbundelementen die oben genannten dekorativen Schichtpreßstoffplatten mit dem Träger dauerhaft verleimt werden müssen, wird die Oberfläche der dekorativen Schichtpreßstoffplatten bei diesen Verfahrensschritten oftmals starken mechanischen Beanspruchungen ausgesetzt. Dies gilt auch für die Weiterverarbeitung der Verbundelemente zu Möbelteilen oder Wandverkleidungen.Since the above-mentioned decorative laminated panels have to be permanently glued to the carrier for the production of composite elements, the surface of the decorative laminated panels is often exposed to strong mechanical stresses during these process steps. This also applies to the further processing of the composite elements into furniture parts or wall cladding.
Der Erfindung liegt deshalb die Aufgabe zugrunde eine oberflächengeschützte dekorative Schichtpreßstoffplatte zu schaffen, sowie ein Verfahren aufzuzeigen, mit dem eine solche dekorative Schichtpreßstoffplatte hergestellt werden kann.The invention is therefore based on the object of providing a surface-protected decorative laminate, and of demonstrating a method with which such a decorative laminate can be produced.
Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruches 1 gelöst.This object is achieved by the features of claim 1.
Ein Verfahren zur Herstellung einer dekorativen Schichtpreßstoffplatte ist in Anspruch 8 offenbart.A method for producing a decorative laminate is disclosed in claim 8.
Die Schutzschicht, welche auf die dekorative Schichtpreßstoffplatte aufgetragen ist, kann zusammen mit dieser bis zu einer Temparatur von 200 °C weiterverarbeitet werden, ohne daß die Schutzschicht dadurch beschädigt wird. Erfindungsgemäß wird die Schutzschicht aus einer Polyester- oder einer Propylenfolie gebildet, die eine Dicke zwischen 0,05 und 0,2 mm aufweist. Die Schutzschicht wird mit Hilfe eines Haftklebers lösbar mit der Oberfläche der dekorativen Schichtpreßstoffplatte verbunden. Das Auftragen der Schutzschicht auf die dekorative Schichtpreßstoff platte erfolgt nach dem Verpressen der Kern- und Dekorpapiere, welche die dekorative Schichtpreßstoffplatte bilden. Die erfindungsgemäße Schutzschicht erlaubt ein Nachformen der dekorativen Schichtpreßstoffplatte, falls diese zur Ausbildung eines. Verbundelementes mit einem Träger verleimt wird, der abgerundete Frontkanten aufweist. Die mit der Schutzschicht ausgerüstete dekorative Schichtpreßstoffplatte kann im Kalt- und Heißtaktverfahren auf Spanplattenträger aufgeleimt werden. Nach dem Verbinden der dekorativen Schichtpreßstoffplatte mit einem Träger zur Bildung eines Verbundelementes bleibt die Schutzschicht weiterhin auf der Oberfläche der dekorativen Schichtpreßstoffplatte. Erst nach dem die dekorativen Schichtpreßstoffplatte selbst oder das Verbundelement, mit dem die dekorative Schichtpreßstoffplatte verleimt ist, vollständig verarbeitet ist, wird die Schutzschicht von der Oberfläche gelöst. Dies ist auf einfache Weise möglich, da die Schutzschicht mit einem Haftkleber auf der Basis von Naturkautschuk oder Acrylharz auf der Oberfläche der dekorativen Schichtpreßstoffplatte gehalten ist. Ein Ablösen der Schutzschicht beim Verpressen oder Verleimen der dekorativen Schichtpreßstoffplatte mit einem Träger, ist durch die Verwendung dieser Haftkleber ausgeschlossen. Die Schutzschicht bietet den Vorteil, daß durch sie die Oberfläche der dekorativen Schichtpreßstoffplatte solange erforderlich geschützt bleibt, das Dekor der Platte jedoch immer sichtbar ist, was die Weiterverarbeitung wesentlich erleichtert. Durch die Schutzschicht wird die Oberfläche der dekorativen Schichtpreßstoffplatte zudem vor Staub und gegen Verkratzen beim Transport sowie gegen Rutsch- und Schleifspuren geschützt. Beim Abtragen der Schutzschicht wird die Bildung von Kleberückständen auf der Dekorschicht vermieden, da nur die oben erwähnten Kleber verwendet werden.The protective layer, which is applied to the decorative laminate, can be further processed together with it up to a temperature of 200 ° C without the protective layer being damaged thereby. According to the invention, the protective layer formed from a polyester or propylene film, which has a thickness between 0.05 and 0.2 mm. The protective layer is releasably connected to the surface of the decorative laminate using a pressure sensitive adhesive. The protective layer is applied to the decorative laminate plate after the core and decorative papers, which form the decorative laminate plate, are pressed. The protective layer according to the invention allows the decorative laminated sheet to be shaped if it is used to form a. Composite element is glued to a carrier that has rounded front edges. The decorative laminated board equipped with the protective layer can be glued to chipboard supports using the cold and hot cycle method. After connecting the decorative laminate with a carrier to form a composite element, the protective layer remains on the surface of the decorative laminate. Only after the decorative laminated panel itself or the composite element with which the decorative laminated panel is glued is completely processed, is the protective layer detached from the surface. This is possible in a simple manner, since the protective layer is held on the surface of the decorative laminate with a pressure-sensitive adhesive based on natural rubber or acrylic resin. A detachment of the protective layer when pressing or gluing the decorative laminate with a carrier is excluded by using this pressure sensitive adhesive. The protective layer has the advantage that the surface of the decorative laminate remains protected for as long as necessary, but the decor of the plate is always visible, which considerably facilitates further processing. The surface of the decorative Laminated board also protected against dust and scratches during transport as well as against slipping and grinding marks. When the protective layer is removed, the formation of adhesive residues on the decorative layer is avoided since only the adhesives mentioned above are used.

Fig. 1 zeigt eine dekorative Schichtpreßstoffplatte 1, die durch einen Kern 2, eine Dekorpapierbahn 3 und eine Schutzschicht 4 gebildet wird. Der Kern 2 der dekorativen Schichtpreßstoffplatte 1 besteht aus mehreren übereinander angeordneten Natronkraftpapierbahnen (hier nicht dargestellt), die mit Phenolharz getränkt sind. Auf diesem Kern 2 ist wenigstens eine Dekorpapierbahn 3 angeordnet. Diese Dekorpapierbahn 3 ist entweder mit einer Farbe eingefärbt oder bedruckt. Die Verbindung der Natronkraftpapierbahnen miteinander zu dem Kern 2 und die Verbindung des Kernes 2 mit der Dekorpapierbahn 3 erfolgt in bekannter Weise durch Verpress en des so gebildeten Papierstapels. Vor dem Auflegen der Dekorbahn 3 auf den Kern 2 wird diese mit einem Aminoplastharz, insbesondere einem Melaminharz getränkt. Nachdem der Kern 2 mit der Dekorpapierbahn 3 dauerhaft verbunden ist, kann die dekorative Schichtpreßstoffplatte 1 mit der erfindungsgemäßen Schutzschicht 4 verbunden werden. Vorzugsweise wird diese Schutzschicht 4 durch eine transparente Kunststoff-Folie gebildet, die aus Polyester oder Polypropylen gefertigt ist. Eine solche Kunststoff-Folie weist den Vorteil auf, daß sie bis 200 °C hitzebeständig ist, was für die Weiterverarbeitung der dekorativen Schichtpreßstoffplatte Voraussetzung ist. Die Schutzschicht 4 weist ein Dicke zwischen 0,05 und 0,2 mm auf. Die aus Polyester oder Polypropylen gefertigte Schutzschicht 4 kann bis zu einer Breite von 2,40 m geliefert werden. Die Folie ist auf einer Rolle aufgewickelt, so daß jede beliebige Länge davon abgenommen werden kann. Dies bietet die .Möglichkeit, die gesamte Oberfläche einer beispielsweise 5 m langen und bis zu 2,40 m breiten dekorativen Schichtpreßstoffplatte mit einer zusammenhängenden Schutzschicht 4 zu überdecken. Da die Schutzschicht 4 hitzebeständig ausgebildet ist, kann sie mit der dekorativen Schichtpreßstoffplatte 1 nachträglich verforrat werden. Die Schutzfolie 4 wird mit Hilfe eines Haftklebers 5 lösbar auf die Oberfläche der Dekorpapierbahn 3 aufgetragen. Es gibt dekorative Schichtpreßstoffplatten, bei denen auf die Dekorpapierbahn 3 zusätzlich eine transparente harzgetränkte Zellulosebahn aufgetragen ist. Bei solchen dekorativen Schichtpreßstoffplatten 1 wird die Schutzschicht 4 dann mit Hilfe des Haftklebers 5 lösbar auf die transparente Zellulosebahn (hier nicht dargestellt) aufgebracht. Nach der Fertigstellung der in Fig.1 dargestellten dekorativen Schichtpreßstoffplatte 1 kann diese mit einem Träger 6A zur Ausbildung eines Verbundelements 6 dauerhaft verbunden werden. Dieser kann aus einem organischen oder anorganischen Material gefertigt werden. Beispielsweise läßt sich der Träger 6A durch das Aufeinanderschichten und Verpressen von harzgetränkten Papierbahnen bilden. Vorzugsweise wird, wie bei dem hier dargestellten Ausführungsbeispiel als Träger 6A eine Spanplatte verwendet. Selbstverständlich kann zur Ausbildung eines Verbundelementes auch ein Träger 6A verwendet werden, der aus Zement, Beton oder einem Schaumstoff gefertigt ist. Der in Fig.2 dargestellte Träger 6A weist eine abgerundete Frontkante 3R auf. Zur Ausbildung einer dekorativen Oberfläche wird die in Fig.1 dargestellte dekorative Schichtpreßstoffplatte 1 mit der Oberfläche des Trägers 6A dauerhaft verbunden. Die mit der Schutzschicht 4 versehene dekorative Schichtpreßstoffplatte 1 kann mit Hilfe von Wärme so geformt werden, daß auch die abgerundete Frontkante 3R des Trägers 6A vollständig von ihr überdeckt wird. Das Nachformen der dekorativen Schichtpreßstoffplatte 1 erfolgt mit Hilfe von Wärme und Druckrollen, mit denen die dekorative Schichtpreßstoffplatte 1 der Form der abgerundeten Frontkante 3R entsprechend gebogen wird. Die dauerhafte Verbindung der dekorativen Schichtpreßstoffplatte 1 mit dem Träger 3 erfolgt durch Verleimen.Fig. 1 shows a decorative laminated sheet 1, which is formed by a core 2, a decorative paper web 3 and a protective layer 4. The core 2 of the decorative laminated sheet 1 consists of several stacked sodium kraft paper webs (not shown here) which are impregnated with phenolic resin. At least one decorative paper web 3 is arranged on this core 2. This decorative paper web 3 is either colored with a color or printed. The connection of the sodium kraft paper webs to one another to form the core 2 and the connection of the core 2 with the decorative paper web 3 is carried out in a known manner by pressing the stack of paper thus formed. Before the decorative sheet 3 is placed on the core 2, it is impregnated with an aminoplast resin, in particular a melamine resin. After the core 2 is permanently connected to the decorative paper web 3, the decorative laminated sheet 1 can be connected to the protective layer 4 according to the invention. This protective layer 4 is preferably formed by a transparent plastic film which is made of polyester or polypropylene. Such a plastic film has the advantage that it is heat-resistant up to 200 ° C, which is a prerequisite for the further processing of the decorative laminate. The protective layer 4 has a thickness between 0.05 and 0.2 mm. The protective layer 4 made of polyester or polypropylene can be supplied up to a width of 2.40 m. The film is wound on a roll so that any length can be removed. This offers the possibility of covering the entire surface of a decorative laminate, for example 5 m long and up to 2.40 m wide, with a coherent protective layer 4. Since the protective layer 4 is designed to be heat-resistant, it can subsequently be betrayed with the decorative laminate 1. The protective film 4 is releasably applied to the surface of the decorative paper web 3 with the aid of a pressure sensitive adhesive 5. There are decorative laminated sheets in which a transparent resin-impregnated cellulose web is additionally applied to the decorative paper web 3. In the case of such decorative laminate panels 1, the protective layer 4 is then releasably applied to the transparent cellulose web (not shown here) with the aid of the pressure sensitive adhesive 5. After the completion of the in Fig.1 The decorative laminate plate 1 shown can be permanently connected to a carrier 6A to form a composite element 6. This can be made from an organic or inorganic material. For example, the carrier 6A can be formed by stacking and pressing resin-impregnated paper webs. As in the embodiment shown here, a particle board is preferably used as the carrier 6A. Of course, a carrier 6A can also be used to form a composite element, which carrier is made of cement, concrete or a foam. The carrier 6A shown in FIG. 2 has a rounded front edge 3R. To form a decorative surface, the decorative laminate 1 shown in FIG. 1 is permanently bonded to the surface of the carrier 6A. The decorative laminated sheet 1 provided with the protective layer 4 can be shaped with the aid of heat so that it also completely covers the rounded front edge 3R of the carrier 6A. The decorative laminate 1 is reshaped with the aid of heat and pressure rollers with which the decorative laminate 1 is bent in accordance with the shape of the rounded front edge 3R. The permanent connection of the decorative laminate 1 to the carrier 3 is done by gluing.
In Fig. 3 ist ein fertiggestelltes Verbundelement 6 dargestellt. Wie anhand von Fig.3 zu sehen ist, wird die gesamte Oberfläche des Trägers 6A einschließlich der abgerundeten Frontkante 3R von der dekorativen Schichtpreßstoffplatte 1 überdeckt. Die erfindungsgemäße Schutzschicht 4 wird mit Hilfe des Haftklebers 5 so fest auf der Oberfläche der dekorativen Schichtpreßstoffplatte gehalten, daß es weder beim Verleimen noch beim Verpressen mit dem Träger 6A zu einem Ablösen der Schutzschicht 4 kommt. Das fertiggestellte Verbundelement 6 kann nunmehr auch mechanisch bearbeitet, insbesondere zu einem Möbelstück oder einer Wandverkleidung weiterverarbeitet werden.
