Abstract
Description
Die Erfindung bezieht sich auf ein Baumaterial aus nach wachsenden Rohstoffen und ein entsprechendes Verfahren zur Herstellung des Baumaterials nach den Merkmalen der Oberbegriffe der Ansprüche 1 und 7.The invention relates to a building material from growing raw materials and a corresponding process for the production of the building material according to the characteristics of Preambles of claims 1 and 7.
Derartige Baumaterialien werden im Bauwesen insbesondere zur Wärme- und Schalldämmung von Gebäuden eingesetzt.Such building materials are used in particular in the construction industry used for thermal and acoustic insulation of buildings.
Herkömmliche Baumaterialien aus Beton und Ziegelstein sind zu schwer und zu wärmeleitend.Conventional building materials made of concrete and brick are too heavy and too heat conductive.
Zur Vermeidung dieser Nachteile ist es bereits bekannt, den Betonbausteinen wärmedämmende Zuschlagstoffe wie beispielsweise textile Fasern, Holzspäne oder Kunst stoffgranulat beizumischen. Ein solcher Baustein ist in der DE 43 20 852 A1 beschrieben, der als Zuschlagstoff granuliertes oder aufgeschäumtes Polystyrol aufweist. Es ist zur Verbesserung der Wärmeeigenschaften von Bau materialien weiterhin bekannt, separate Wärmedämmplatten vorzublenden und anschließend zu verkleiden. Solche Wär medämmplatten bestehen üblicherweise aus Polystyrol ver schiedenster Prägung. To avoid these disadvantages, it is already known the concrete blocks heat-insulating aggregates such as for example textile fibers, wood chips or art Mix in granulate. Such a building block is in DE 43 20 852 A1 described as an aggregate has granulated or foamed polystyrene. It is used to improve the thermal properties of construction known materials, separate thermal insulation panels fade in and then dress up. Such war Insulation boards are usually made of polystyrene ver various types.
Der wesentliche Nachteil der Verwendung von Baumateria lien aus Polystyrol oder dgl. besteht darin, daß sie nur als Sondermüll entsorgt werden können. Polystyrolplatten haben weiterhin den Nachteil, für die Außenschicht unge eignet zu sein. Sie müssen aus Gründen der schlechten Ansicht und des geringen Verschleißverhaltens stets mit einem Kleber, einem Putz oder einem Verblendmauerstein verkleidet werden. Solche Verkleidungen sind aufwendig herzustellen und verschlechtern obendrein die Atmungsak tivität solcher Wände.The main disadvantage of using construction materials lien from polystyrene or the like. Is that they only can be disposed of as hazardous waste. Polystyrene sheets still have the disadvantage of being unskilled for the outer layer to be suitable. They have to be for the sake of bad View and the low wear behavior always with an adhesive, a plaster or a facing brick to be disguised. Such claddings are expensive to manufacture and worsen the respiratory tract activity of such walls.
Außerdem gast Polystyrol in gesundheitsgefährdender Wei se aus.In addition, polystyrene is a health-endangering white se out.
Es besteht daher die Aufgabe, ein gattungsgemäßes Bauma terial zum Dämmen zu entwickeln, das neben den anerkann ten Eigenschaften eines Dämmaterials in der Anwendung diffusionsfähig und nach der Anwendung vollständig bio logisch abbaubar ist und dazu ein entsprechendes Verfah ren zu seiner Herstellung zu entwickeln.There is therefore the task of a generic Bauma to develop material for insulation that, in addition to the recognized properties of an insulating material in use diffusible and completely organic after use is logically degradable and a corresponding procedure to develop its production.
Diese Aufgabe wird sachlich dadurch gelöst, daß das Bau material vollständig aus nachwachsenden Rohstoffen, näm lich aus C4-Gras und Hanf zu etwa gleichen Anteilen besteht.This task is solved objectively in that the construction material made entirely from renewable raw materials, näm made from C4 grass and hemp in roughly equal proportions consists.
Es ist zweckmäßig das Baumaterial als ein Trockengemisch auszuführen und als Zuschlagstoff für Putze, Schüttungen oder vorgefertigte Bauelemente zu verwenden.The building material is expedient as a dry mixture Execute and as an additive for plasters, fillings or use prefabricated components.
Es ist auch zweckmäßig, das Baumaterial unter Zusatz von 9,8 Gew.-% C4-Gras, 8,4 Gew.-% Hanf, 5,8 Gew.-% Verfesti ger, 3,2 Gew.-% Bindemittel und 72,8 Gew.-% Wasser als ei ne gesonderte Dämmplatte auszubilden.It is also appropriate to add the building material 9.8% by weight C4 grass, 8.4% by weight hemp, 5.8% by weight Verfesti ger, 3.2 wt .-% binder and 72.8 wt .-% water as egg ne separate insulation board.
Dabei wird flüssiger Latex als Verfestiger und Zellulose als Bindemittel eingesetzt. Liquid latex is used as a solidifier and cellulose used as a binder.
Verfahrensmäßig wird die Aufgabe nach den kennzeichnen den Merkmalen der Ansprüche 7 und 8 gelöst.In terms of procedure, the task will be labeled according to solved the features of claims 7 and 8.
Dieses Baumaterial hat besondere Vorteile. Zunächst ist die Anwendungsvielfalt hervorzuheben. Das Baumaterial kann ein Trockengemisch sein und in einfa cher Weise vorzugsweise einem Mörtel- oder Lehmputz zu gegeben werden, wodurch der Putz schall- und wärmedäm mende Eigenschaften erhält.This building material has special advantages. First of all, the variety of applications should be emphasized. The Building material can be a dry mix and in simple terms cher way preferably a mortar or clay plaster are given, which makes the plaster sound and heat insulating properties.
Außerdem wird die Rißbildung der Putze vermindert. Er kann aber auch eine gesonderte Dämmplatte sein und in bekannter Weise auf ein Mauerwerk befestigt werden. Auch damit werden sehr gute Dämmeigenschaften des Mauerwerks erreicht.The cracking of the plasters is also reduced. But it can also be a separate insulation board and in known way to be attached to masonry. Also this creates very good insulation properties of the masonry reached.
Dabei hat sich als besonders vorteilhaft herausgestellt, daß die Mauerwerke in jedem der Anwendungsfälle ihre Diffusionseigenschaften erhalten.It has been found to be particularly advantageous that the masonry in each of the applications Obtain diffusion properties.
Es hat sich auch gezeigt, daß das Baumaterial über gute direkte Hafteigenschaften gegenüber Fliesen, Putz und Tapete besitzt. Außerdem ist das Baumaterial leicht und gut zu bearbeiten. Auf Grund des relativ hohen Silizium gehaltes des C4-Grases ist das Baumaterial nur schwer entflammbar.It has also been shown that the building material has good properties direct adhesive properties to tiles, plaster and Owns wallpaper. In addition, the building material is light and easy to edit. Because of the relatively high silicon content of the C4 grass, the building material is difficult flammable.
Es wurde weiter festgestellt, daß das Baumaterial sehr gute Saugfähigkeiten besitzt und somit auch als ein Bin der von schädigenden Flüssigkeiten, beispielsweise von Ölen eingesetzt werden kann.It was also found that the building material was very has good absorbency and therefore also as a bin of harmful liquids, for example of Oils can be used.
Sowohl als Dämmplatte oder als Ölbinder ist das Baumate rial vollständig biologisch abbaubar und erfüllt somit hohe ökologische Anforderungen. This is both as an insulation board or as an oil binder rial completely biodegradable and thus fulfills high ecological requirements.
Die Erfindung wird anschließend an Hand zweier Ausfüh
rungsbeispiele vorgestellt und ihre Herstellungsverfah
ren näher erläutert.
The invention is then presented on the basis of two exemplary embodiments and their manufacturing processes are explained in more detail.
-
1. Das Baumaterial zum Dämmen besteht aus etwa 54 Gew.-%
C4-Gras und aus etwa 46 Gew.-% Hanf, das zu einem
Trockengemisch verarbeitet ist.
Zur Herstellung dieses Trockengemisches werden das C4-Gras und der Hanf in getrennter Weise grob zu einer Teilchengröße von etwa 1-3 cm zerkleinert und anschließend bei normaler Raumtemperatur und normalem Luftdruck 6-12 Monate getrocknet. Durch eine hinlänglich bekannte Variation der Trocknungsbedingungen kann diese Trock nungszeit erheblich verringert werden. Anschließend wird das getrocknete C4-Gras bzw. Hanf feingemahlen. Dabei wird eine Teilchengröße von etwa 0,1 bis 4 mm ange strebt. Das C4-Graspulver und das Hanfpulver werden an schließend trocken miteinander vermischt.
Dieses Trockengemisch wird z. B. einem Mörtelputz als Zu schlagstoff mit einem Anteil von etwa 5 Gew.-% beigegeben und zusammen mit dem Mörtel auf herkömmliche Beton- oder Ziegelbauelemente aufgetragen.1. The building material for insulation consists of about 54 wt .-% C4 grass and about 46 wt .-% hemp, which is processed into a dry mixture.
To produce this dry mixture, the C4 grass and the hemp are roughly crushed separately to a particle size of about 1-3 cm and then dried at normal room temperature and atmospheric pressure for 6-12 months. This drying time can be considerably reduced by a well-known variation of the drying conditions. Then the dried C4 grass or hemp is finely ground. A particle size of about 0.1 to 4 mm is aimed for. The C4 grass powder and the hemp powder are then dry mixed together.
This dry mixture is used for. B. a mortar plaster as an impact material with a share of about 5 wt .-% and applied together with the mortar to conventional concrete or brick components. -
2. Das Baumaterial besteht aus etwa 9.8 Gew.-% C4-Gras,
etwa 8,4 Gew.-% Hanf, etwa 5,8 Gew.-% flüssigem Latex als
Verfestiger und etwa 3,2 Gew.-% Zellulose als Bindemittel
sowie die restlichen 72,8 Gew.-% Wasser und ist zu einer
Dämmplatte verarbeitet.
Dazu wird ein nach dem ersten Ausführungsbeispiel herge stelltes Trockengemisch verwendet. Daneben wird ein Feuchtgemisch mit den restlichen Bestandteilen Wasser, Zellulose und Latex in den genannten Konzentrationen hergestellt, in dem zunächst die Zellulose dem Wasser zugegeben und nach einer Quell zeit von etwa 12 h der La tex eingemischt wird.
Das Trockengemisch und das Feuchtgemisch werden dann un ter ständigem Rühren zu einem Fertiggemisch vermischt, wobei eine weitere Quell zeit von etwa 12 h erforderlich ist. Dieses Fertiggemisch wird anschließend gepreßt und bei Raumtemperatur und normalen Luftverhältnissen etwa 18 Tage getrocknet. Es versteht sich, daß diese Trock nungsdauer stark von der Größe der Dämmplatten abhängt. Beim Trocknungsprozeß ist besonderer Wert auf eine be stimmte Luftfeuchte zu legen, damit die gepreßte Dämm platte einerseits nicht schimmelt und sich andererseits nicht verzieht. Zuletzt wird die Dämmplatte in herkömm licher Weise auf die gewünschten Maße geschnitten.2. The building material consists of approximately 9.8% by weight of C4 grass, approximately 8.4% by weight of hemp, approximately 5.8% by weight of liquid latex as a solidifier and approximately 3.2% by weight of cellulose as a binder as well as the remaining 72.8% by weight of water and is processed into an insulation board.
For this purpose, a dry mixture produced according to the first embodiment is used. In addition, a moist mixture with the remaining constituents of water, cellulose and latex is produced in the stated concentrations, in which the cellulose is first added to the water and the La tex is mixed in after a swelling time of about 12 hours.
The dry mixture and the wet mixture are then mixed under continuous stirring to give a finished mixture, a further swelling time of about 12 hours being required. This finished mixture is then pressed and dried at room temperature and normal air conditions for about 18 days. It is understood that this drying duration depends strongly on the size of the insulation panels. During the drying process, special emphasis should be placed on a certain atmospheric humidity, so that the pressed insulation board does not go moldy on the one hand and does not warp on the other hand. Finally, the insulation board is cut to the desired dimensions in a conventional manner.
