Abstract
Description
Die Erfindung betrifft Holzwerkstoffe für den Möbel- und Innenausbau, insbesondere Spanplatten aus großflächigen Spänen.The invention relates to wood-based materials for furniture and interior construction, in particular Chipboard made from large-scale chips.
Eine wesentliche Voraussetzung für den weltweit rasanten Anstieg der Produktion von Spanplatten und Oriented Strand Boards, kurz als OSB bezeichnet, und das hohe Produktionsvolumen in den letzten Jahrzehnten war, daß von der chemischen Industrie in großem Umfang preiswerte synthetische Klebstoffe, insbesondere Aminoplastharze, bereitgestellt werden konnten.An essential prerequisite for the rapid increase in production worldwide of chipboard and oriented beach boards, briefly referred to as OSB, and that high production volume in the past few decades was that of chemical Industry on a large scale inexpensive synthetic adhesives, in particular Aminoplast resins could be provided.
Zu den entscheidenden verarbeitungstechnischen Eigenschaften dieser Klebstoffe gehören neben ihrer einfachen Handhabung ihre hohe Reaktivität für die Realisierung kurzer Preßzeiten. Von Vorteil sind ihr hoher Festharzgehalt bei relativ niedriger Viskosität.The decisive processing properties of these adhesives In addition to their simple handling, their high reactivity for implementation is one of them short pressing times. The advantage of their high solid resin content is relatively low Viscosity.
Spanplatten und OSB werden besonders in Europa und auch weltweit, abgesehen von einigen Fertigungsstätten und Spezialprodukten, derzeit fast ausschließlich mit synthetischen Klebstoffen als Bindemittel erzeugt. In Europa dürfte der Anteil der Bindemittel auf Basis von Aminoplasten (UF-Harze und die sogenannten Mischkondensate) zur Herstellung von Holzwerkstoffen gegenwärtig bei 90% liegen.Chipboard and OSB are particularly disregarded in Europe and worldwide of some manufacturing facilities and special products, currently almost exclusively with synthetic adhesives produced as binders. In Europe, the share of Binders based on aminoplasts (UF resins and the so-called Mixed condensates) for the production of wood-based materials are currently 90%.
Das zunehmende Umweltbewußtsein hat jedoch in bestimmten Verbraucherkreisen zur Skepsis gegenüber der ständig zunehmenden Chemisierung von Herstellungsprozessen geführt. Hervorzuheben sind dabei die Sorge um Umweltbelastungen bzw. die Einhaltung von Umweltauflagen bei der Produktion, das verbreitete Bedürfnis, natürlich und in einem schadstofffreiem Innenraumklima zu wohnen, sowie Fragen des umweltfreundlichen Recyclings und der Entsorgung der Abfälle bzw. der Erzeugnisse nach ihrem Gebrauch. However, environmental awareness has increased in certain consumer circles to the skepticism about the constantly increasing chemization of Manufacturing processes led. The concern for should be emphasized Environmental pollution or compliance with environmental regulations during production, the widespread need, naturally and in a pollutant-free indoor climate to live, as well as questions of environmentally friendly recycling and disposal waste or products after their use.
Obwohl die Formaldehydabgabe der aminoplastgebundenen Holzwerkstoffe weiter hin gesenkt werden konnte, kann das Problem "Formaldehyd" noch immer nur als teilweise gelöst angesehen werden. Ursachen dafür sind möglicherweise einzelne Lieferungen aus Importen oder bestimmte Chargen mit noch relativ hohem Formaldehydgehalt, aber auch gelegentlich neu entfachte Diskussionen in der Öffentlichkeit. So ist die Substitution von synthetischen Bindemitteln durch natürliche Bindemittel auf Basis nachwachsender Rohstoffe für die Herstellung von Holzwerk stoffen ein Ziel der Entwicklung.Although the release of formaldehyde from the aminoplast-bound wood-based materials continues The problem of "formaldehyde" can still only be reduced as can be viewed partially resolved. This may be due to individual reasons Deliveries from imports or certain batches that are still relatively high Formaldehyde content, but also occasionally newly sparked discussions in the Publicity. So is the substitution of synthetic binders by natural ones Binder based on renewable raw materials for the manufacture of woodwork fabrics a goal of development.
Es sind zahlreiche Verfahren und Literaturangaben zur Herstellung von Spanwerk stoffen aus großflächigen Spänen und speziell mit orientierten Spänen bekanntge worden, in denen die Art der Bindemittel näher beschrieben bzw. begründet wurde.There are numerous processes and references to the production of chipboard known from large-scale chips and especially with oriented chips in which the type of binder has been described or justified.
Spanwerkstoffe aus langen, orientierten Spänen stellte Stofko (1962) mit einem Phenol-Resol-Harz her. Deppe (1974) beschreibt eine amerikanische Bauspanplatte, eine "Wafer"-Platte, die 1,5% Phenolharz aufweist. Es ist bekannt, Spanwerkstoffe aus großflächigen Spänen, wie z. B. das Waferboard-Produkt "Waferboard-plus" unter Anwendung eines pulverförmigen Phenolharzes herzustellen (Moeltner 1980).Stofko (1962) provided chip materials from long, oriented chips with one Phenol resole resin. Deppe (1974) describes an American particle board, a "wafer" plate containing 1.5% phenolic resin. It is known chip materials from large chips, such as B. the Waferboard product "Waferboard-plus" using a powdered phenolic resin (Moeltner 1980).
Platten aus großflächigen Spänen werden unter Verwendung von Strands, d. h., Späne mit einer Länge von 20 bis 70 mm, einer Breite von 3 bis 10 mm und einer Dicke von 0,3 bis 0,6 mm unter Verwendung eines Harnstoff-Formaldehyd- Bindemittels erzeugt (Blümer 1981). Neben Waferboard werden auch Strandboard unter Anwendung von Phenolleimpulver produziert (Walter 1981). Platten aus langen, schlanken, ausgerichteten Spänen, heute im allgemeinen als OSB bezeichnet, werden mit Harnstoffharz oder mit Phenolharz, letzteres sowohl als Flüssigleim als auch als Pulverharz, hergestellt (Sitzler 1984). Daneben kommen auch Mischkondensate, z. B. ein flüssiger MUPF-(Melamin-Harnstoff-Phenol- Formaldehyd) Leim zur Anwendung (Sitzler 1994).Large area chips are cut using strands, e.g. H., Chips with a length of 20 to 70 mm, a width of 3 to 10 mm and one Thickness from 0.3 to 0.6 mm using a urea formaldehyde Binder produced (Blümmer 1981). In addition to wafer boards, there are also beach boards produced using phenol powder (Walter 1981). Plates out long, lean, aligned chips, now commonly known as OSB are called with urea resin or with phenolic resin, the latter both as Liquid glue as well as powder resin, manufactured (Sitzler 1984). Come alongside also mixed condensates, e.g. B. a liquid MUPF- (melamine-urea-phenol- Formaldehyde) glue for use (Sitzler 1994).
Näher untersucht wurden Mischharzverleimungen bei der OSB-Herstellung, bei denen die großflächigen "strands" ausschließlich mit Kunstharz-Bindemitteln beleimt wurden (Deppe, Hasch 1989). Eine zusammenhängende Darstellung dazu geben Deppe und Ernst (1991). Weiterhin sind OSB, die mit kombinierten Bindemittel systemen gebunden werden, wie Phenolharze in den Deckschichten und PMDI in der Mittelschicht oder MUPF mit PMDI in jüngster Zeit behandelt worden (Boehme 1998). Mixed resin gluing in OSB production was examined in more detail at to which the large-area "strands" are glued exclusively with synthetic resin binders were (Deppe, Hasch 1989). Give a coherent presentation Deppe and Ernst (1991). Furthermore, OSB are combined with binders systems, such as phenolic resins in the top layers and PMDI in the middle class or MUPF have recently been treated with PMDI (Boehme 1998).
Alle vorstehend beschriebenen Spanwerkstoffe aus großflächigen Spänen sind mit dem Nachteil behaftet, daß zu ihrer Herstellung synthetische Bindemittel Anwendung finden und damit ökologisch mit Einschränkungen bewertet werden. Insbesondere die vollständig oder teilweise mit Aminoplastharzen erzeugten Spanwerkstoffe stoßen, insbesondere bei Anwendung in Innenräumen, wegen ihrer Formaldehydabgabe auf Skepsis in Verbraucherkreisen mit geschärftem Umweltbewußtsein.All chip materials from large-area chips described above are included suffers from the disadvantage that synthetic binders for their production Find application and thus be assessed ecologically with restrictions. In particular, those that are produced entirely or partially with aminoplast resins Chip materials encounter, especially when used indoors, because of their Formaldehyde release on skepticism in consumer circles with sharpened Environmental awareness.
Dabei sind auch die Nachteile der möglichen Umweltbelastungen bei der späteren Entsorgung der Werkstoffe und daraus hergestellter Erzeugnisse hervorzuheben.There are also the disadvantages of possible environmental pollution in the later Emphasis on disposal of materials and products made from them.
Das Ziel der vorliegenden Erfindung ist es, einen Werkstoff aus großflächigen orientierten Spänen mit einem natürlichen, formaldehydfreien Bindemittelsystem auf Basis nachwachsender Rohstoffe herzustellen, das frei von synthetischen Bindemitteln ist. Der Werkstoff soll damit bei seiner Herstellung und Verarbeitung sowie im Gebrauch und bei seiner späteren Entsorgung höchsten ökologischen Anforderungen entsprechen.The aim of the present invention is to make a material from large areas oriented chips with a natural, formaldehyde-free binder system To produce the basis of renewable raw materials that are free of synthetic Binders. The material is said to be used in its manufacture and processing as well as the highest ecological use and later disposal Meet requirements.
