Description
BeschreibungDescription
Die Neuerung betrifft ein zellul.osehaltiges Preßteil bestehend aus durch ein aushärtbares Bindemittel verbundenen Pflanzenteilen.The innovation concerns a pressed part containing cellulose consisting of plant parts bonded together by a hardenable binding agent.
Solche Preßteile sind als Spanplatten bekannt, bei denen Holzspäne mit synthetissehen Klebern verbunden sind. Spanplatten werden vorwiegend in der Bau- und Möbelindustrie, aber z.B. auch als vielseitig einzusetzender Werkstoff für Heimwerker verwendet.Such pressed parts are known as chipboards, in which wood chips are bonded with synthetic adhesives. Chipboards are used primarily in the construction and furniture industries, but also as a versatile material for do-it-yourselfers.
Durch die Verwendung synthetischer Stoffe bei der Herstellung von Spanplatten verursachen sie gewisse Umweltprobleme, z.B. durch Abgabe von gasformigen Bestandteilen bei Gebrauch und Entsorgung.The use of synthetic materials in the production of chipboards causes certain environmental problems, e.g. through the release of gaseous components during use and disposal.
Der Neuerung liegt die Aufgabe zugrunde, umweltfreundliche Preßteile zu schaffen, die bei Herstellung, Gebrauch und Entsorgung keine besonderen Probleme bieten und die außerdem besonders kostengünstig bisher zumindest teilweise ungenutzt bleibende Abfallstoffe einer sinnvollen Nutzung zuführen können. The innovation is based on the task of creating environmentally friendly pressed parts that do not pose any particular problems during production, use and disposal and that can also put previously at least partially unused waste materials to sensible use in a particularly cost-effective manner.
Die Lösung besteht darin, daß das Bindemittel aus Naturprodukten besteht. Dabei kann es sich um pflanzliche öle, wie etwa Leinöl, Ricinusöl oder Holzöl handeln, um Baumharze, wie Kolophonium, um Milchsäure-Kasein, um Kalk, Wasserglas, Natur-Kautschuk in Form von Gummimilch, um tierische Leime, wie z.B. Haut- und Knochenleime, oder um Schellack. Diese Bindemitel können in reiner oder kombinierter Form und auch gemischt mit anderen natürlichen Bindemitteln benutzt werden.The solution is that the binding agent consists of natural products. These can be vegetable oils such as linseed oil, castor oil or wood oil, tree resins such as colophony, lactic acid casein, lime, water glass, natural rubber in the form of rubber milk, animal glues such as hide and bone glue, or shellac. These binding agents can be used in pure or combined form and also mixed with other natural binding agents.
Besonders vorteilhaft ist es, wenn die Pflanzenteile Stroh oder Getreidekleie (Schalen) sind, weil diese Naturprodukte bisher nur teilweise sinnvoll genutzt werden und in großen Mengen durch Verbrennen beseitigt werden.It is particularly advantageous if the plant parts are straw or grain bran (husks), because these natural products have so far only been partially used sensibly and are disposed of in large quantities by burning.
Nach einer bevorzugten Ausf iihrungsf &ogr; rm werden die Preßteile in Plattenform gestaltet.According to a preferred embodiment, the pressed parts are designed in plate form.
Die beigefügte Zeichnung zeigt als erläuterndes Ausführungsbeispiel einen Schnitt durch eine Preßplatte 10, wobei 12 kurzgehäckselte Strohteile und 14 einen natürlichen Binder bezeichnet.The attached drawing shows, as an explanatory example, a section through a press plate 10, where 12 designates short chopped straw parts and 14 a natural binder.
