An Independent claim is included for a process for the production of (I) from vegetable fibers by intimately mixing the components and pressing in an appropriate mold or by continuous processing of the mixing in appropriate press installations, preferably a plate or band press and drying.

Description

Die vorliegende Erfindung betrifft Dämmelemente, insbesondere Bauplatten, aus pflanzlichen Materialien mit einem Anteil von Lehm, die mittels wasserlöslichem Silikat gebunden sind.The present invention relates to insulation elements, in particular building boards vegetable materials with a share of clay, which is water-soluble Silicate are bound.

Dämmelemente werden zur Schalldämmung eingesetzt und dienen dem Vermei­ den von Wärmeverlusten durch Wärmeleitung. Sie bestehen häufig aus syntheti­ schen Polymeren, wie z. B. Polystyrol, Polyurethan sowie mineralischen Materia­ lien wie, Steinwolle, Glaswolle, expandiertem Vermiculit.Insulation elements are used for sound insulation and serve to avoid that of heat loss through heat conduction. They often consist of syntheti polymers such as. B. polystyrene, polyurethane and mineral materia lien like, rock wool, glass wool, expanded vermiculite.

In der Patentanmeldung DE 42 11 732 und in der Gebrauchsmusteranmeldung DE 295 06 761 werden Isoliermatten aus Flachsfasern beschrieben. Zur Herstel­ lung dieser Dämmplatten ist jedoch die vorherige, aufwendige Gewinnung von Bastfasern erforderlich, die nur zu rd. 22% im Stroh der Faserpflanze enthalten sind. In the patent application DE 42 11 732 and in the utility model application DE 295 06 761 describes insulating mats made from flax fibers. For the manufacture However, this insulation board is the previous, complex extraction of Bast fibers are required, which are only approx. 22% contained in the straw of the fiber plant are.  

Gegenstand der vorliegenden Erfindung sind daher Dämmelemente aus gehäk­ selten Materialien einjähriger Pflanzen, wie z. B. Stroh von Getreide-pflanzen, wie Roggen, Weizen, Gerste, Hafer, Mais, Sorghum oder von faserliefernden Pflanzen, wie Öl- und Faserlein, Hanf, Jute, Kenaf oder Ramie sowie deren Mi­ schungen. Das Stroh der Faserpflanzen kann ganz, teilweise oder überhaupt nicht, von Bastfasern befreit sein. Bei einem hohen Bastfasergehalt ist jedoch die Ver­ arbeitung schwieriger, so daß es sinnvoll ist, mittels geeigneter Schneidemaschi­ nen für eine Einkürzung der Faseranteile Sorge zu tragen. Als wasserlösliche Si­ likate eignen sich Natrium-, Kalium-, und quaternäre Ammoniumsilikate, sowie deren Mischungen.The present invention therefore relates to insulation elements made from crochet rare materials of annual plants, such as B. straw from cereal plants, such as rye, wheat, barley, oats, corn, sorghum or from fiber suppliers Plants, such as oil and fiber flax, hemp, jute, kenaf or ramie and their Mi. worked. The straw of the fiber plants can be wholly, partially or not at all, be freed of bast fibers. With a high bast fiber content, however, the Ver work more difficult, so that it makes sense to use a suitable cutting machine to ensure a reduction in the fiber content. As water-soluble Si Likates are sodium, potassium, and quaternary ammonium silicates, as well their mixtures.

Da die ausgehärteten Alkalisilikate eine recht spröde Bindung darstellen, ist es sinnvoll, diesen Cellulose- und Stärkederivaten - wie beispielsweise Carboxy­ methylcellulose, Alkylcellulose, Hydroxyalkylcellulose, Stärke, Phosphatstärke, Hydroxyalkylstärke - oder Alginate, Polyurethane, Polyacrylate, Polymaleinate Polyvinylpyrolidon, Bentonite oder organisch modifizierte Bentonite, sowie Xanthane oder Proteide, wie Casein, als zusätzliche Binderkomponente einzuset­ zen. Es kann sinnvoll sein zur Verbesserung bestimmter Eigenschaften den Mi­ schungen weiterhin Borsäure, Alkaliborate und Ammoniumborate zuzusetzen.Since the hardened alkali silicates represent a very brittle bond, it is sensible, these cellulose and starch derivatives - such as carboxy methyl cellulose, alkyl cellulose, hydroxyalkyl cellulose, starch, phosphate starch, Hydroxyalkyl starch - or alginates, polyurethanes, polyacrylates, polymaleinates Polyvinyl pyrolidone, bentonite or organically modified bentonite, and Xanthans or proteins, such as casein, can be used as an additional binder component Zen. It can be useful to improve certain properties of the Mi addition of boric acid, alkali borates and ammonium borates.

Die Herstellung der beanspruchten Dämmelemente erfolgt in der Weise, daß zu­ erst die gehäkselten Pflanzenteile in einen Mischer mit der erforderlichen Menge Alkalisilikatlösung bzw. Mischungen aus Alkalisilikaten und den oben erwähnten Stärke- und Celluloseabkömmlingen innig vermischt werden. Dies kann auch durch Besprühen während des Mischvorgangs erfolgen. In einer zweiten Stufe erfolgt das Untermischen der Lehmkomponente. Dies gelingt am besten durch allmähliches Zudosieren oder Einstreuen des Lehms in das vorher erzeugte Mischgut. Die Mischungsverhältnisse lassen sich in einem weiten Be­ reich variieren. The production of the claimed insulation elements takes place in such a way that First the crocheted parts of plants in a mixer with the required amount Alkali silicate solution or mixtures of alkali silicates and the above mentioned starch and cellulose derivatives are intimately mixed. This can also be done by spraying during the mixing process. In a second stage, the clay component is mixed in. This succeeds on best by gradually adding or sprinkling the clay into the previously generated mix. The mixing ratios can be widely vary widely.  

Die Formteile werden dann durch Eintragen der Mischung in geeignete Formen und anschließendem Pressen oder - bei einer kontinuierlichen Herstellung von Dämmplatten- durch Einbringen in geeignete Pressanlagen, wie z. B. Platten- oder Bandpressen, erhalten.The molded parts are then made by inserting the mixture into suitable molds and subsequent pressing or - in a continuous production of Insulation boards by inserting them into suitable press systems, such as B. plate or Belt presses received.

Das Aushärten kann sowohl durch lagern bei Normaltemperatur, als auch in ge­ eigneten Trockenöfen erfolgen.The curing can be done both by storing at normal temperature and in ge suitable drying ovens.

Die so erzeugten Dämmelemente wirken feuchtigkeitsregulierend in beide Rich­ tungen, da sie atmungsaktiv sind. Sie sind als biologisch einwandfrei anzusehen, so daß weder bei Abfallplatten während des Einbaus noch bei einem späteren Ausbau keinerlei Entsorgungsprobleme entstehen.The insulation elements produced in this way have a moisture-regulating effect in both directions as they are breathable. They are considered to be biologically sound, so that neither with waste panels during installation nor with a later Expansion no disposal problems arise.
