At the same time, a crosslinking of the aminoplastic resin and a deformation of the entire structure takes place. For the process of crosslinking and curing, the resin may contain suitable catalysts (hardeners).
Nach dem Preßvorgang erhält man einen Rohling mit einer duroplastischen (thermoduren) Oberflächenschicht. Der Rohling kann in der Möbelindustrie zu einer duroplastischen Möbeloberfläche weiterverarbeitet werden.After the pressing process, a blank having a thermosetting (thermodur) surface layer is obtained. The blank can be further processed in the furniture industry to a thermosetting furniture surface.
Gegenüber herkömmlichen thermoplastischen Möbeloberflächen zeichnet sich die erfindungsgemäße duroplastische Möbeloberfläche durch bessere Kratzfestigkeit, Wärmebeständigkeit, Haftung auf dem Trägermaterial, Lichtbeständigkeit, Chemikalienbeständigkeit und Recyclingfähigkeit aus.Compared to conventional thermoplastic furniture surfaces, the thermosetting furniture surface according to the invention is characterized by better scratch resistance, heat resistance, adhesion to the substrate, light resistance, chemical resistance and recyclability.
Es wird ein Träger mit einer vorgegebenen dreidimensionalen Oberflächenkontur verwendet. Exemplarisch sei eine entsprechend vorgefräste MDF-Platte genannt.A carrier with a given three-dimensional surface contour is used. An example is a corresponding pre-milled MDF board called.
Das mit aminoplastischem Harz imprägnierte Dekorpapier wird auf den Träger aufgebracht und zusammen damit in die druckdichte Preßkammer einer Membranpresse gebracht. Die Preßkammer wird durch Anlegen von Vakuum entlüftet. Sodann werden Träger und Dekorpapier mit einer auf 100 °C bis 120 °C vorgeheizten Membran bei einem Druck von 5 bis 18 bar (0,5 bis 1,8 MPa) in einem Arbeitsgang miteinander verpreßt. Der Druck wird durch Druckluft oder temperiertes Öl aufgebracht. Die Dauer des Preßvorgangs beträgt ca. 1 bis 5 min.The decor paper impregnated with aminoplastic resin is applied to the carrier and brought together with it into the pressure-tight press chamber of a membrane press.

In der Membranpresse wird allein das imprägnierte Dekorpapier verformt. Es paßt sich der vorgegebenen Oberflächenkontur des Trägers an und bildet darauf eine duroplastische (thermodure) Oberflächenschicht. Bei diesem Typ von Presse wird der Träger nicht mit verformt.In the membrane press alone the impregnated decor paper is deformed. It adapts to the given surface contour of the carrier and forms a thermoset surface layer thereon. In this type of press, the carrier is not deformed.
Das verwendete Dekorpapier hält den Belastungen stand, die beim Formprägepressen und Membranpressen unter gleichzeitiger Verformung des Papiers und Aushärtung des aminoplastischen Harzes einhergehen. Es tritt keine Rißbildung auf. Maßgeblich dafür ist, daß das Papier einen Faseranteil Baumwoll-Linters von mindestens 10 Gew.% hat. Im Ergebnis erhält man durch Verpressen eines Dekorpapiers erstmals eine dreidimensional verformte duroplastische Oberflächenschicht.The decor paper used withstands the stresses associated with compression molding and membrane pressing while simultaneously deforming the paper and curing the aminoplastic resin. There is no cracking. Decisive for this is that the paper has a fiber content of cotton linters of at least 10% by weight. As a result, by pressing a decorative paper, a three-dimensionally deformed thermosetting surface layer is obtained for the first time.
