Abstract

The compound board has a board carrier body and an applied decorative layer, of natural materials. The carrier is generally of lignin. The carrier is of lignin with natural fibers such as hemp, cellulose, wood and the like, as reinforcement. The decorative layer is a wood veneer, nonwoven, braiding, woven, knitted material, or laid bands of fibers, using natural fiber materials. An Independent claim is included for a manufacturing process, where the decorative layer is pressed against a board carrier of lignin, to be bonded together by heat and pressure. Preferred Features: The lignin carrier is reinforced with natural fibers. The decorative layer is bonded to the carrier in a press at a pressure of 40-400 bar at a temperature of 120-180 deg C. A number of different decorative layers can be overlaid or overlapped in the press, and bonded to the carrier together. A fiber layer can be placed over the decorative layer, and the decorative layer surface can be given a profiled structure.

Description

Die Erfindung betrifft einen Verbundkörper, bestehend aus einem im wesentlichen plattenförmigen Träger und wenig­ stens einer mit diesem verbundenen Dekorschicht aus einem natürlichen Werkstoff. Sie ist ferner auf ein Verfahren zur Herstellung eines derartigen Verbundkörpers gerich­ tet.The invention relates to a composite body consisting of a substantially plate-shaped carrier and little at least one of a decorative layer connected to it natural material. She is also on trial for the production of such a composite body tet.

Bei der Produktion von Möbeln, Verkleidungen oder groß­ flächigen Bauteilen werden meist Platten aus Holz oder Holzwerkstoffen verwendet. Hochwertige Massivholzplatten werden dabei aus einzelnen Vollholzbrettern mit unter­ schiedlichen Fügetechniken, wie Leimen oder Fügen, zu großflächigen Platten weiterverarbeitet. Durch den Durch­ messer eines gewachsenen Baumstamms sind die maximalen Abmessungen eines Einzelbretts vorgegeben, was die Her­ stellung von Bauteilen aus Massivholz in Form von z. B. größeren Platten limitiert. In the production of furniture, paneling or large Flat components are usually made of wood or panels Wood-based materials used. High quality solid wood panels are made from individual solid wood boards with under different joining techniques, such as gluing or joining large plates processed. Through the through the maximum of a grown tree trunk Dimensions of a single board given what the Her provision of components made of solid wood in the form of z. B. larger plates limited.  

Die Holzindustrie versucht dies dadurch zu kompensieren, daß Holzabfälle in Form von Spänen zusammen mit vorwie­ gend synthetischen Bindern zu Platten verpreßt werden. Dabei spielt insbesondere der Formaldehydgehalt der verwendeten Leime eine nachteilige Rolle in Bezug auf die toxischen bzw. krebserzeugenden Emissionen aus den auf diese Weise hergestellten Span- bzw. Faserplatten.The timber industry tries to compensate for this by that wood waste in the form of chips together with enough synthetic binders to be pressed into plates. The formaldehyde content of the used glue an adverse role in terms of toxic or carcinogenic emissions from the particleboard or fiberboard produced in this way.

Die Veredelung der Oberflächen solcher Spanplatten wird im nachhinein entweder mit Echtholz- oder Kunststoff­ funieren in aufwendigen Beleimungs- und Preßverfahren realisiert. Eine weitere Limitierung dieser Art der Plattenerzeugung stellt die erschwerte Produktion von nicht ebenen Bauteilen dar, die nur unter Heißdampf bis zu einem gewissen Grad der Umformung hergestellt werden können.The finishing of the surfaces of such chipboard is afterwards either with real wood or plastic function in complex gluing and pressing processes realized. Another limitation of this type of Plate production represents the difficult production of not flat components that are only exposed to superheated steam to a certain degree of forming can.

Der Erfindung liegt die Aufgabe zugrunde, einen Verbund­ körper der eingangs genannten Art vorzuschlagen, der kostengünstig herstellbar ist, holzähnliche Eigenschaften besitzt, eine klebstofffreie Fertigung ermöglicht, um­ weltfreundlich und mittels bekannter thermoplastischer Verarbeitungsverfahren umformbar ist.The invention has for its object a composite to propose body of the type mentioned at the outset is inexpensive to produce, wood-like properties possesses, an adhesive-free production enables to world-friendly and using known thermoplastic Processing method is deformable.

Diese Aufgabe wird erfindungsgemäß mit einem Verbundkör­ per gemäß einem der Ansprüche 1 bis 4 gelöst. Ein Verfah­ ren zur Herstellung eines derartigen Verbundkörpers ist durch die Ansprüche 7 bis 16 gekennzeichnet.This object is achieved with a composite body per solved according to one of claims 1 to 4. A procedure ren for the production of such a composite body characterized by claims 7 to 16.

Ein plattenförmiger Träger auf der Basis von Lignin, der gegebenenfalls mit Naturfasern als Verstärkung versetzt werden kann und so die geforderten holzähnlichen Eigen­ schaften aufweist, besitzt eine holzähnliche Haptik und Optik. Durch die Verwendung dieses holzähnlichen Werk­ stoffes, der zu 100% aus nachwachsenden Rohstoffen aufge­ baut und außerdem thermoplastisch verarbeitbar ist, besteht die Möglichkeit, bindemittelfreie, großflächige bzw. -volumige Platten oder dreidimensionale Bauteile mit einem geringen Zeitaufwand herzustellen. Durch die Mög­ lichkeit der Haftung von Echtholzfurnieren oder Naturfa­ servliesen aller Art können attraktive Sichtflächen realisiert werden, und zwar in einem Schritt im Zuge der Herstellung der plattenförmigen Bauteile.A plate-shaped carrier based on lignin, the optionally mixed with natural fibers as reinforcement can be and so the required wood-like properties has a wood-like feel and  Optics. By using this wood-like work material that is made up of 100% renewable raw materials builds and can also be processed thermoplastically, there is the possibility of binder-free, large-area or -volume plates or three-dimensional components with to manufacture in a short time. By the poss liability of real wood veneers or natural fa Servliesen of all kinds can create attractive visible surfaces can be realized in one step in the course of Production of the plate-shaped components.

Die Produktion der Platten kann z. B. mittels Heißpressen im Fließpreßverfahren mit Zykluszeiten unter zwei Mixnuten erreicht werden, was die Voraussetzung für eine wirt­ schaftliche Fertigung darstellt.The production of the plates can e.g. B. by means of hot pressing in the extrusion process with cycle times under two mix grooves be achieved, which is the prerequisite for one represents economic production.

Der erfindungsgemäße Verbundkörper kann in Form von Platten beliebiger Dicke mit oder ohne Holzfurnieren, Fasermatten oder sonstigen dekorativen Oberflächen im Möbelbau, Hausbau, in der Automobilindustrie oder als gepreßte Holzgehäuse für elektronische Erzeugnisse aller Art Verwendung finden. Er kann weiterhin als Gehäuseteil mit Holzcharakter für Telefone oder Handys, Computer-, Monitor-, Lautsprecher- oder Fernsehgehäuse, Parkettbö­ den, Holzdecken, Türinnenverkleidungen, Zierleisten, Instrumententafeln oder dergleichen verwendet werden, wobei er mit beliebigen Holzarten furniert sein kann.The composite body according to the invention can be in the form of Panels of any thickness with or without wood veneer, Fiber mats or other decorative surfaces in the Furniture, house building, in the automotive industry or as pressed wooden housing for electronic products of all Kind of use. It can still be used as a housing part with wooden character for telephones or cell phones, computer, Monitor, speaker or television housing, parquet gust wooden ceilings, door linings, moldings, Instrument panels or the like are used, whereby it can be veneered with any kind of wood.
