Abstract

The intermediate veneer product comprises at least two veneer layers (1) which are at most 0.3 mm thick and are joined to one another by a thermoplastic or thermally hardenable glue (2).

Description

Die Erfindung betrifft ein dreidimensional verformbares Furnierhalbzeug aus vorwiegend Holz zur Oberflächenbeschichtung oder zur Herstellung von Erzeugnissen.The The invention relates to a three-dimensionally deformable veneer semifinished product from predominantly wood for surface coating or for the manufacture of products.

Furnierhalbzeuge sind bekannt.Semi-finished veneer are known.

Weit verbreitet sind Schichtwerkstoffe, insbesondere Sperrholz, aus mehreren miteinander verklebten Furnieren. Vorwiegend wird ebenflächiges Sperrholz hergestellt und verarbeitet. Bekannt ist aber auch die Herstellung dreidimensional verformter Schichtholzerzeugnisse bzw. verformbarer Furnierhalbzeuge.Far common are coating materials, in particular plywood, of several glued together veneers. Predominantly, planar plywood will be used made and processed. But also known is the production three-dimensionally shaped laminated wood products or deformable Semi-finished veneer.

Im einfachsten Fall werden einzelne mit einer Klebstoff-Folie beschichtete Furnierblätter für die Beschichtung von dreidimensional geformten Oberflächen, z. B. von Möbeln oder Autoteilen hergestellt. Die Klebstoff-Folie ist vorwiegend aus einem thermoplastischen Werkstoff. Beim Pressen des Furniers auf die Oberfläche wird der Klebstoff aufgeschmolzen und das Furnier verformt. Das einzelne Furnierblatt ist gut verformbar, aber es reißt leider sehr leicht ein und scheidet hierdurch für die Beschichtung stärker gekrümmter Oberflächen aus.in the In the simplest case, individual coated with an adhesive film veneers for the Coating of three-dimensionally shaped surfaces, eg. B. of furniture or car parts. The adhesive film is predominant made of a thermoplastic material. When pressing the veneer up the surface The adhesive is melted and the veneer deformed. The single veneer sheet is well malleable, but it unfortunately rips very easily and thus exudes for the coating of more curved surfaces.

Nach DD 268 667 wird ein Schichtmaterial unter Verwendung von Polypropylen-Folien und zusätzlichem Haftklebstoff auf Basis Polyisobuthylen zwischen den Furnieren beschrieben, bei dessen Herstellung eine zähe Viskosität des Klebstoffs eingestellt wird. Dieses Schichtmaterial ist bei Raumtemperatur einerseits bearbeitbar und andererseits schubverformungsfähig. Die Furniere, angegeben werden 0,7 mm starke Buchenholzfurniere, können sich beim Kaltbiegen gegeneinander verschieben. In Streifen geschnitten erfolgt ein Anpressen auf vorgeleimte Schmalflächen. Zusätzlich wird die Haftung infolge Klebfugenalterung durch Abdunsten der Restanteile des Lösungsmittels verfestigt.To DD 268 667 For example, a sheet material is described using polypropylene films and additional polyisobutylene-based pressure-sensitive adhesive between the veneers, the production of which sets a viscous viscosity of the adhesive. This layer material is on the one hand editable and on the other hand shear deformable at room temperature. The veneers, which are given 0.7 mm thick beech wood veneers, can move against each other during cold bending. Cut into strips, a pressing on vorgeleimte narrow surfaces. In addition, the adhesion is solidified due to adhesive joint aging by evaporation of the residual proportions of the solvent.

In DE 299 08 123 U1 werden mehrere Furnierlagen mit dazwischen liegenden Polyäthylenfolien zunächst zu einem ebenflächigen Laminat bei vorzugsweise 65°C bis 70°C verpresst. Beim anschließenden Formpressen mit erhöhter Temperatur zwischen 100°C und 150°C vernetzt dieser Klebstoff und härtet aus. Verwendet wird ein thermoaktiver nachvernetzender Kleber.In DE 299 08 123 U1 several veneer layers are pressed with intervening polyethylene sheets first to a planar laminate at preferably 65 ° C to 70 ° C. During the subsequent compression molding with elevated temperature between 100 ° C and 150 ° C, this adhesive cross-links and hardens. A thermoactive post-curing adhesive is used.

Gemäß DD 206 102 werden reversibel festwerdende Klebstoffe (Thermoplastfolien, insbesondere Polyäthylenfolien) bzw. irreversibel aushärtende Klebstoffe (Harnstoffharz oder Klebstoffdispersionen, insbesondere PVac) eingesetzt und ebenfalls in zwei Stufen gepresst.According to DD 206 102 are used reversibly festfestdende adhesives (thermoplastic films, especially polyethylene films) or irreversibly curing adhesives (urea resin or adhesive dispersions, in particular PVac) and also pressed in two stages.

In WO 2003103909 wird die Lösung über die Auswahl spezieller Hölzer gesucht. Insbesondere soll das mittlere von 3 Furnieren ein 0,7 mm dickes Furnier einer Frühpappel sein. Klebstoff ist PVac.In WO 2003103909 is the solution over the selection special woods searched. In particular, the middle of 3 veneers should be 0.7 mm thick veneer of a early poplar be. Adhesive is PVac.

Aufgabe der Erfindung ist es, eine weitere Möglichkeit zur Herstellung von sehr flexiblen dreidimensional gut verformbaren Furnierhalbzeugen vorzuschlagen.task The invention is a further possibility for the production of very flexible three-dimensional, easily deformable veneer semi-finished products propose.

Erfindungsgemäß wird die Aufgabe durch ein Furnierhalbzeug aus wenigstens zwei Lagen von höchstens 0,3 mm dicken Furnieren, die mit einem thermoplastischen bzw. thermisch nachhärtbaren Klebstoff miteinander verbunden sind, gelöst.According to the invention Task by a semi-finished veneer from at least two layers of at most 0.3 mm thick veneers with a thermoplastic or thermal post-hardenable adhesive connected to each other, solved.

Vorzugsweise besteht das Halbzeug aus drei über Kreuz gelegten bzw. gleichgerichteten Furnieren.Preferably the semi-finished product consists of three Crossed or rectified veneers.

Das Halbzeug ist durch die dünnen Lagen und dadurch, dass der Klebstoff zumindest bis zum endgültigen Aushärten ausreichend viskos bzw. aufschmelzbar ist, sehr flexibel und unter Druck und Wärme stark dreidimensional verformbar. Der übliche nachfedernde Widerstand der Furniere gegen die Verformung ist gering. Zumindest die äußeren Lagen kühlen rasch ab und halten die Form. Zugleich ist das Halbzeug gut handhabbar, weil es auch bei zwei Lagen bereits einen festen, angemessen strapazierfähigen Verbund ergibt.The Semi-finished product is through the thin Layers and in that the adhesive is sufficient at least until final curing viscous or meltable, very flexible and strong under pressure and heat three-dimensionally deformable. The usual nachfedernde resistance of the veneers against deformation is low. At least the outer layers cool quickly and keep the shape. At the same time, the semi-finished product is easy to handle, because it is already in two layers already a solid, reasonably durable composite results.

Das Furnierhalbzeug eignet sich sehr gut zum Laminieren von Möbeln, Autoteilen etc., darunter insbesondere von dreidimensional geformten Oberflächen. Es können sehr teure Hölzer verarbeitet werden, da der Materialeinsatz gering ist.The Semi-finished veneer is very suitable for laminating furniture, car parts etc., including in particular of three-dimensionally shaped surfaces. It can very expensive woods be processed because the material usage is low.

Darüber hinaus können aus dem Halbzeug auch Fertigerzeugnisse, wie z. B. Schalen oder Gehäuse, hergestellt werden.Furthermore can From the semi-finished and finished products, such. B. shells or Casing, getting produced.

Vorzugsweise werden thermoplastische Klebefolien auf der Basis von Polyurethanen oder Polyethylen-Vinylacetat eingesetzt.Preferably are thermoplastic adhesive films based on polyurethanes or polyethylene-vinyl acetate used.

Die Erfindung wird nachfolgend an einem Ausführungsbeispielen näher erläutert. In den Zeichnungen zeigenThe The invention will be explained in more detail below using an exemplary embodiment. In show the drawings
