Abstract

In a process for manufacturing a reinforced product from natural raw materials a pasteurised heat curing natural raw material(4) is forced through an extrusion die(15) together with continuous twisted natural fibres(3), the latter being held under tension in the curing natural material matrix by the injection force exerted on the cured part of the product and a braking system at the fibre unwinding drum(2).

Description

Anwendungsgebietfield of use

Das Verfahren betrifft die Verarbeitung von Naturrohstoffen geringer Festigkeit - z. B. landwirtschaftliche Abfallprodukte - in Kombination mit hochfesten Einlagen.The process concerns the processing of natural raw materials of low strength - e.g. B. agricultural waste products - in combination with high-strength deposits.

Stand der TechnikState of the art

Es ist bekannt, Produkte aus zerkleinerten Naturrohstoffen in beliebigen Formen herzustellen. Das gebräuchlichste Verfahren findet bei der Herstellung von Preßspanplatten Anwendung. Hier wird Holz zerkleinert, mit einem Verbindungsmittel gemischt und in einer Form unter Druck und Temperatur ausgehärtet. Ebenso ist bekannt, die Belastbarkeit derartiger Bauteile durch Armierungen beliebiger Materialart und Form zu erhöhen.It is known to produce products from crushed natural raw materials in any form to manufacture. The most common process takes place in the production of particle board Application. Here wood is crushed, mixed with a lanyard and in one Mold hardened under pressure and temperature. Resilience is also known to increase such components by reinforcement of any material type and shape.

Nachteile des Standes der TechnikDisadvantages of the prior art

Erzeugnisse aus plastisch geformten Naturrohstoffen ohne Armierung erfordern einen hohen Materialeinsatz, was eine große Eigenmasse nach sich zieht.Products made of plastically shaped natural raw materials without reinforcement require one high use of materials, which entails a large weight.

Hohe Belastbarkeit bei geringer Eigenmasse ist nur unter Anwendung von Armierungen und der Ausbildung von Hohlkörpern erreichbar. Bekannte Verfahren zur Realisierung dieser Forderung sind aufwendig und in ihrer Anwendungsbreite eingeschränkt.High resilience with low weight is only possible when using reinforcements and the formation of hollow bodies. Known methods of realizing this Demand are complex and limited in their range of applications.

Aufgabe der ErfindungObject of the invention

Aufgabe der Erfindung ist es, ein Verfahren zu schaffen, nach dem es möglich wird, pasteurisierte Naturrohstoffe mit hochfesten Naturfasern, vorrangig als Hohlkörper effektiv zu verarbeiten.The object of the invention is to provide a method according to which it is possible Pasteurized natural raw materials with high-strength natural fibers, primarily effective as hollow bodies to process.

Lösung der AufgabeSolution of the task

Die Lösung der Aufgabe ist in den Ausführungsbeispielen gemäß Fig. 1 und 2 erläutert. Die Vorteile der erfindungsgemäßen Lösung liegen hauptsächlich in der Einfachheit des Verfahrens und der daraus resultierenden Formenvariabilität der Erzeugnisse. Die Kombination vorgespannter hochfester Naturfasern mit landwirtschaftlichen Abfallprodukten und deren Ausbildung als Hohlkörper eröffnet den Einsatz als Konstruktionselemente vorrangig im Trockenbau der Bauwirtschaft.The solution to the problem is explained in the exemplary embodiments according to FIGS. 1 and 2. The advantages of the solution according to the invention lie mainly in the simplicity of the process and the resulting variability in the shape of the products. The combination of pre-stressed high-strength natural fibers with agricultural waste products and their formation as hollow bodies opens up the use as construction elements primarily in drywall construction.

AusführungsbeispielEmbodiment

In Fig. 1 ist das Verfahren in vertikaler Anordnung ohne externe Spritzeinheit dargestellt. Von den Trommeln 2 können die Naturfaserfäden 3 gegen einen definierten Widerstand abgezogen werden. Diese werden durch den pasteurisierten Naturrohstoff durch den Trichter 5 in den Spitzkopf 15 geführt. In der Mikrowellenstation 8 und in der Wärmeein­ heit 9 wird der pasteurisierte Naturrohstoff 4 verfestigt und dadurch die Naturfaser 3 fixiert. Der Druck des eingespritzten Schaumstoffes 12 bewirkt eine Kraftwirkung des ausgehär­ teten Formteiles in Transportrichtung. Dadurch entsteht eine kontinuierliche Zugspannung auf die Naturfasern 3. Dies bewirkt, daß die Naturfasern 3 in vorgespanntem Zustand im aushärtenden pasteurisierten Naturrohstoff 4 fixiert werden. Die Transporteinheit 10 unter­ stützt erforderlichenfalls den Transport des Formteiles. In der Schnitteinheit 11 wird das Formteil auf die gewünschte Länge geschnitten. Gemäß der Darstellung in Fig. 2 trans­ portiert die Spritzeinheit 13 den pasteurisierten Naturrohstoff 4 zum Dosierkopf 14. An die­ sem sind Dichtlippen so angeordnet, daß der Spritzdruck das aushärtende Werkstück in Spritzrichtung treibt. Der übrige technologische Ablauf erfolgt wie in Fig. 1 dargestellt. Der Spritzkopf 15 gibt dem Profil die äußere Form und ist wegen der besseren Entformbar­ keit in Spritzrichtung erweitert. Zur Modifizierung der Materialeigenschaften kann auch statt des pasteurisierten Naturrohstoffes Kunststoff und/oder statt der Naturfaserarmierung metallische Werkstoffe eingesetzt werden.In Fig. 1 the method is shown in a vertical arrangement without an external injection unit. The natural fiber threads 3 can be drawn off from the drums 2 against a defined resistance. These are guided through the funnel 5 into the pointed head 15 by the pasteurized natural raw material. In the microwave station 8 and in the heat unit 9 , the pasteurized natural raw material 4 is solidified, thereby fixing the natural fiber 3 . The pressure of the injected foam 12 causes a force effect of the molded part in the transport direction. This creates a continuous tension on the natural fibers 3 . This causes the natural fibers 3 to be fixed in the hardened pasteurized natural raw material 4 in the prestressed state. The transport unit 10 supports, if necessary, the transport of the molded part. In the cutting unit 11 , the molded part is cut to the desired length. As shown in FIG. 2, the injection unit 13 transports the pasteurized natural raw material 4 to the dosing head 14 . At the sem sealing lips are arranged so that the spray pressure drives the curing workpiece in the spray direction. The rest of the technological process is as shown in Fig. 1. The spray head 15 gives the profile the outer shape and is expanded in the spraying direction because of the better mold release. To modify the material properties, plastic materials can also be used instead of the pasteurized natural raw material and / or metallic materials instead of natural fiber reinforcement.
