Description
"Dekorative Schichtstoffplatte" Die Erfindung betrifft eine dekorative Schichtstoffplatte mit Träger- und Dekorschicht."Decorative laminate board" The invention relates to a decorative Laminate board with carrier and decorative layer.
Es sind bereits Schichtstoffplatten verschiedener Art bek n Atgeworden, die eine Dekorschicht und eine Trägerschicht aufweisen. Sie können aus verschiedenen bahnenförmigen Trägermaterialien aufgebaut sein, z. B. Vliesen, die mit härtbaren oder thermoplastischen Harzen imprägniert bzw. beschichtet worden sind. Mehrere solcher Bahnen gleicher oder verschiededener Art können gegebenenfalls unter Einwirkung von Wärme und Druck vereinigt sein. Besonders häufig werden Bahnen von Natronkraftpapier als Träger verwendet, die mit Phenol- oder Kresolharz imprägniert sind. An diese schließt sich dann ein oder beidseitig mindestens ein mit Harnstoff- oder Melaminharz imprägnierter, gegebenenfalls unifarbiger oder dekorativ bedruckter Bogen aus Zellulose an. Die Gesamtstärke solcher Schichtstoffplatten beträgt im allgemeinen 0,7 bis 1,5 mm.Laminate panels of various types have already been known which have a decorative layer and a carrier layer. You can choose from different be constructed in sheet-like carrier materials, e.g. B. nonwovens with curable or thermoplastic resins have been impregnated or coated. Several Such tracks of the same or different types can, if necessary, be affected be united by heat and pressure. Sheets of soda kraft paper are particularly common used as a carrier impregnated with phenolic or cresol resin. To this then closes one or both sides at least one with urea or melamine resin Impregnated, possibly plain-colored or decoratively printed sheet made of cellulose at. The total thickness of such laminate panels is generally 0.7 to 1.5 mm.
Es wurde nun auch schon bekannt, eine solche Schichtstoffplatte dadurch aufzubauen, daß man die meist nur aus einer Papierlage bestehende Dekorschicht auf eine ebenfalls einschichtige Kern- bzw. Trägerlage entsprechender Stärke, etwa Vulkanfieber, aufbringt. Diese Lösung konnte bisher nicht befriedigen.It has now also become known that such a laminate board can be produced by this build up that you usually only consist of a paper layer decorative layer a single-layer core or carrier layer of the same thickness, such as volcanic fever, brings up. So far, this solution has not been satisfactory.
Angesichts des ökonomischen Aufwandes, wie er zur Umwandlung von Holz bzw. Holzfaserprodukten in Papier notwendig ist, schien es erstrebenswert, eine Schichtstoffplatte zu schaffen, die mit einer Trägerschicht aus Holzfaser- bzw. Holzschnitzelstoffen auskommt. Dadurch werden die hohen Kosten für die Herstellung der einzelnen Papiere sowie deren Tränkung mit Harz entbehrlich.Given the economic outlay involved in converting wood or wood fiber products in paper is necessary, it seemed desirable to achieve a To create a laminate board with a carrier layer made of wood fiber or Wood chips. This reduces the high cost of manufacture the individual papers as well as their impregnation with resin can be dispensed with.
Obwohl es seit langem bekannt ist, übliche Schichtstoffplatten auf Holzspanplatten vorzugsweise in den Stärken 8 bis 30 mm ein- oder beidseitig aufzubringen, ist doch bisher offensichtlich nicht der Versuch gellacht worden, eine dünne dekorative Schichtstoffplatte auf Holzträgerbasis herzustellen.Although it has long been known, common laminate boards are based on To apply chipboard, preferably 8 to 30 mm thick, on one or both sides, so far, the attempt has obviously not been laughed at, a thin decorative Produce laminated board on a wooden base.
Die Lösung der vorgenannten Aufgabe ist überraschenderweise gelungen und dadurch gekennzeichnet, daß die Trägerschicht eine etwa 1 bis 5 mm starke Spanplatte mit einem Gehalt an wärmehärtbaren Harzen von etwa 8 bis 35 Gew. % und die Dekorschicht eine ansich bekannte mit einem wärmehärtbaren Harz imprägnierte Papierschicht ist.The solution to the above-mentioned problem has surprisingly been successful and characterized in that the carrier layer is an approximately 1 to 5 mm thick chipboard With a content of thermosetting resins of about 8 to 35% by weight and the decorative layer is a known thermosetting resin impregnated paper layer.
Hierbei hat sich als besonders wichtig der Harzgehalt erwiesen, der von dem üblicher Spanplatten abweicht. Weiterhin war es notwendig, von Spanplatten auszugehen, die normalerweise nicht voll ausgehärtet sind. Andernfalls könnte es bei dem zweimaligen Heizpreßendurchgang unter Druck zu einer ttberhärtung und damit Versprödung des Materials kommen, was eine Zerstörung des Stangefüges zur Folge haben kann.The resin content has proven to be particularly important here differs from the usual chipboard. Furthermore, it was necessary from chipboard that are usually not fully cured. Otherwise it could in the two heat press passes under pressure to over-hardening and thus The material becomes brittle, which results in the rod structure being destroyed may have.
Das Verfahren zur Herstellung der erfindungsgemäßen Schichtstoffplatten ist demgemäß dadurch gekennzeichnet, daß die mit wärmehärtbaren Harzen getränkte Spanplatte nicht voll ausgehärtet ist und mit der Dekorschicht unter einem Druck von 70 bis 120 kp/cm2 und Temperaturen von 120 bis 150 0C verpreßt wird.The process for producing the laminated panels according to the invention is accordingly characterized in that the thermosetting resins impregnated Chipboard is not fully cured and with the decorative layer under a pressure of 70 to 120 kp / cm2 and temperatures of 120 to 150 0C is pressed.
Weitere Merkmale der erfindungsgemäßen dekorativen Schichtstoffplatte ergeben sich aus den Unteransprüchen.Further features of the decorative laminate board according to the invention result from the subclaims.
Der neuartige Aufbau der Dekorschichtstoffplatten erlaubt im übrigen fast alle die Anwendungen, die von bekannten Schichtstoffplatten her geläufig sind. Unter angepaßten Herstellbedingingen ist auch die Verwendung geprägter Preßbleche oder Zulagebogen möglich,um der Dekorschicht eine räumliche Strukturierung zu verleihen. Sofern die Schichtstoffplatte nur einseitig mit Dekorpapier versehen ist, enthält sie auf der anderen Seite ein Gegenzugpapier.The new structure of the decorative laminate panels also allows almost all of the applications that are familiar from known laminate panels. The use of embossed press plates is also subject to adapted manufacturing conditions or additional sheets possible to give the decorative layer a spatial structure. If the laminate board is only provided with decorative paper on one side, contains on the other side a counter paper.
In dem fc;genden Beispiel mit zugehöriger Figur wird der erfindungsgemäße Aufbau der Schichtstoffplatte näher erläutert.In the following example with the associated figure, the inventive Structure of the laminate board explained in more detail.
Dabei ist mit 1 die im Falle des Beispieles einlagig gewählte Dekorschicht bezeichnet, mit 2 der Spanplattenträger und mit 3 das Gegenzugpapier. Selbstverständlich sind insbesondere bei dickeren Spanplatten zwischen 3 bis 5 mm auch Schichtstoffplatten denkbar, die auf beiden Seiten eine Dekorschicht aufweisen und selbsttragend eingesetzt werden. Häufiger ist natürlich die Verwendung einseitig dekorativ ausgestatteter Schichtstoffplatten und deren Aufbringung auf stärkere Trägerplatten etc.In this case, 1 is the decorative layer selected as a single layer in the case of the example denotes, with 2 the chipboard support and with 3 the counter-pulling paper. Of course Laminate panels are also particularly suitable for thicker chipboard between 3 and 5 mm conceivable, which have a decorative layer on both sides and are used in a self-supporting manner will. More often, of course, is the use of one-sided decorative features Laminate panels and their application to thicker carrier panels, etc.
