Description
Kombinationswerkstoff sowie Verfahren zu seiner HerstellungCombination material and process for its production
Die Erfindung betrifft einen Kombinationswerkstoff sowie ein Verfahren zu des- sen Herstellung. Insbesondere betrifft die Erfindung einen Werkstoff, der Holzfasern oder Holzspäne oder beides enthält.The invention relates to a combination material and a method for its production. In particular, the invention relates to a material containing wood fibers or wood chips or both.
Holzwerkstoffe wie Spanplatten, Platten mit orientierten Langspänen (OSB), Hochdichte Faserplatten (HDF) und Mitteldichte Faserplatten (MDF) werden gegenwärtig aus relativ hochwertigen Holzsortimenten unter Zugabe von dem späteren Verwendungszweck angepassten Bindemitteln üblicherweise im Trok- kenverfahren hergestellt. Durch spezielle Zusätze können den Werkstoffen Eigenschaften, wie reduzierte Wasseraufnahme und dadurch verminderte Dik- kenquellung, Schwerentflammbarkeit und/oder bedingte Resistenz gegenüber biologischen Schädigungen verliehen werden. Für die industrielle Holzwerkstoffherstellung werden Bindemittelrezepturen auf der Basis von Harnstoff- Formaldehydharz (UF), Melamin-Hamstoff-Formaldehydharz (MUF), Melamin- Harnstoff-Phenol-Formaldehydharz (MUPF), Phenol-Formaldehydharz (PF) oder polymeren Diisocyanaten (PMDI) eingesetzt. Zur Verbesserung der Was- serabweisung werden bis zu 1 ,5 % Hydrophobierungsmittel (z. B. Paraffin) zugesetzt. Der Feststoffanteil der Bindemittel beträgt bei den UF-, MUF-, MUPF- oder PF-Harzen 5 bis 20 %, bei den PMDI-Klebstoffen etwa 2 bis 6 %, jeweils bezogen auf atro Holzpartikelmasse /Deppe, Ernst 1996: MDF - Mitteldichte Faserplatten, DRW-Verlag Weinbrenner GmbH & Co., Leinfelden- Echterdingen; Deppe, Ernst 2000: Taschenbuch der Spanplattentechnik, 4. Auflage, DRW-Verlag Weinbrenner GmbH & Co., Leinfelden-Echterdingen/.Wood-based materials such as chipboard, boards with oriented long chips (OSB), high-density fiberboard (HDF) and medium-density fiberboard (MDF) are currently made from relatively high-quality wood with the addition of binders adapted to the intended use. Special additives can give the materials properties such as reduced water absorption and thus reduced thickness swelling, flame retardancy and / or conditional resistance to biological damage.

In jüngster Zeit wurden auch Lösungen erarbeitet, um in Werkstoffen auf der Basis von Fasern oder Partikeln die üblicher weise eingesetzten Harze durch Lackkoagulate oder Pulverlackabfälle zu ersetzen, beispielsweise für Dämmmatten oder Türverkleidungselemente im Automobil (DE 3936974 C1), Faservlies-Formteile (DE 4441765 A1) oder Holzpartikelwerkstoffe (DE 10129750 A1). Der Nachteil dieser Lösungen besteht darin, dass für die Herstellung der Werkstoffe wegen der zur Vernetzung der Substitute erforderlichen Wärmeenergie höhere Presstemperaturen und/oder unwirtschaftlich lange Presszeiten erforderlich sind.In recent times, solutions have also been developed to replace the commonly used resins in materials based on fibers or particles with paint coagulates or powder paint waste, for example for Insulating mats or door trim elements in automobiles (DE 3936974 C1), nonwoven molded parts (DE 4441765 A1) or wood particle materials (DE 10129750 A1). The disadvantage of these solutions is that higher press temperatures and / or uneconomically long press times are required for the production of the materials because of the thermal energy required to crosslink the substitutes.
