Description

Die Erfindung betrifft ein Verfahren zur Herstellung eines harten Preßkörpers, bei welchem granulierter Polyurethan-Hartschaum mit einem Bindemittel verpreßt wird.The invention relates to a method for producing a hard pressed body, in which granulated rigid polyurethane foam is pressed with a binder.

Ein Verfahren dieser Art ist aus der FR-PS 13 72 091 bekannt. Ferner wurde in der DE-PS 21 20599 bereits die Verwendung eines solchen Preßkörpers zum Aufsaugen von öl beschrieben. Solche Preßkörper haben sich insbesondere in Form von Platten zum Aufsaugen von öl u. dgl. hervorragend bewährtA method of this type is known from FR-PS 13 72 091. Furthermore, in DE-PS 21 20 599 already the use of such a compact for sucking up oil is described. Such compacts have proven to be particularly effective in the form of plates for sucking up oil and the like

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, die Herstellung von Preßkörpern der genannten Art zu verbilligen und außerdem das Verfahren so abzuwandeln, daß der Preßkörper in seinen Eigenschaften auf verschiedene Einsatzgebiete abstimmbar istThe present invention has for its object the production of pressed bodies of mentioned type to cheaper and also to modify the process so that the pressed body in its properties can be adapted to different areas of application

Erfindungsgemäß wird diese Aufgabe dadurch gelöst,According to the invention, this object is achieved by

daß dem granulierten Polyurethan-Hartschaum und dem Bindemittel mindestens ein weiteres ölaufsaugendes Mittel in Form von Pulver, Granulat, Flocken, Schnitzeln und/oder Fasern vor dem Verpressen beigemischt wird.that the granulated rigid polyurethane foam and the binder at least one further oil-absorbent Preparations in the form of powder, granules, flakes, chips and / or fibers before pressing is added.

Auf diese Weise kann man den ölaufsaugenden Preßkörper beispielsweise speziell auf die Viskosität des aufzusaugenden Öles oder Fremdstoffes abstimmen. Ferner lassen sich auf diese Weise die Wärme- und Schalldämmeigenschaften des Preßkörpers, wenn er beispielsweise als Bauplatte eingesetzt wird, beeinflussen. In this way you can, for example, specifically to the viscosity of the oil-absorbent pressed body Coordinate the oil or foreign matter to be sucked up. Furthermore, in this way, the heat and Sound insulation properties of the pressed body, for example, when it is used as a building board, affect.

Eine vorteilhafte Ausgestaltung des erfindungsgemäßen Verfahrens besteht darin, zusätzliche Füllstoffe, wie Papierschnitzel, Textilfasern od. dgl., beizumischen. Auf diese Weise läßt sich nicht nur der Preis des ölaufsaugenden Preßkörpers beeinflussen, sondern beispielsweise auch seine Auftriebseigenschaften auf Wasser od. dgl.An advantageous embodiment of the method according to the invention consists in adding additional fillers, such as Shredded paper, textile fibers or the like. To be mixed in. In this way, not only can the price of the affect the oil-absorbing compact, but also, for example, its buoyancy properties Water or the like

Als Bindemittel können ein Zweikomponentenkleber auf Epoxi-, Polyester-, Phenol- oder Polyurethanharzbasis bzw. Kautschukbasis verwendet werden. Alternativ dazu kann als Bindemittel auch ein Einkomponentenkleber auf Stärkebasis oder ein selbstaushärtendes Leimgemisch wie Knochenleim verwendet werden. Auch die Auswahl des Bindemittels richtet sich nach dem Verwendungszweck und/oder den vorgesehenen Herstellkosten.A two-component adhesive based on epoxy, polyester, phenol or polyurethane resin or rubber can be used as the binding agent. Alternatively, a one-component starch-based adhesive or a self-hardening glue mixture such as bone glue can also be used as the binding agent. The selection of the binding agent also depends on the intended use and / or the intended production costs.

Der nach dem erfindungsgemäßen Verfahren hergestellte Preßkörper kann formbeständig zu einer Platte, einem Würfel, einer Kugel od. dgl. gepreßt sein. Spezifisches Gewicht, Druckfestigkeit, Bruchfestigkeit sowie vor allem das ölaufsaugvermögen läßt sich in weiten Grenzen durch geeignete Wahl und Zusammensetzung der verwendeten ölaufsaugenden Mittel und/ oder Füllstoffe beeinflussen.The pressed body produced by the method according to the invention can be dimensionally stable to form a plate, a cube, a ball or the like. Be pressed. Specific weight, compressive strength, breaking strength and, above all, the oil absorbency can be varied within wide limits through a suitable choice and composition affect the used oil-absorbent agents and / or fillers.
