Verfahren zur Herstellung eines ölaufsaugenden Materials und aus diesem Material bestehende Platte »um Aufsaugen von Ul Process for the production of an oil-absorbent material and a plate consisting of this material »to absorb U1

Die Erfindung betrifft ein Verfahren zur Herstellung eines ölaufeaugenden Materials sowie eine aus diesem Material bestehende Platte zum Aufsaugen von 01.The invention relates to a method for producing a oil-absorbent material as well as one consisting of this material Plate to absorb 01.

Seit längerer Zeit besteht in verschiedenen Wirtschaftsbe-For a long time there has been a

reichen, insbesondere in der metallverarbeitenden Industrie ein Bedürfnis nach ölaufsaugenden Materialien, die absolut staubfrei und einfach einzusetzen sind. Bisher kennt man solche ölaufsaugenden Materialien in Fora von Pulver oder Granulat auf verschiedener Grundlage, beispielsweise Holz, Kork, bestimmten Gesteinsarten, Schlacke, Kunststoff und dergleichen. rich, especially in the metalworking industry, there is a need for oil-absorbent materials that are absolutely dust-free and easy to use. So far, such oil-absorbent materials are known in Fora from Powder or granulate on various bases, for example wood, cork, certain types of rock, slag, plastic and the like.

Ein Nachteil dieser bekannten ölaufsaugenden Materialien besteht darin, daß sie in Form von Pulver oder Granulat vorliegen und daher einerseits nicht an jeder Stelle und für jeden Zweck verwendbar sind und andererseits nicht ab· solut staubfrei sein können.A disadvantage of these known oil absorbent materials consists in the fact that they are in the form of powder or granules and therefore on the one hand not at every point and can be used for any purpose and, on the other hand, cannot be absolutely dust-free.

Durch die Erfindung soll ein Herstellungsverfahren für ein ölaufsaugendes Material geschaffen werden, welches die ge» schilderten Nachteile nicht aufweist, allgemein und an jeder Stelle verwendbar ist und insbesondere bereits vor« beugend an ölgefährdeten Stellen angebracht werden kann, ohne Aussehen und Benutzung solcher Stellen nachteilig zu beeinflussen.The invention is intended to provide a manufacturing method for a oil-absorbent material are created, which the ge » does not have the disadvantages described, can be used in general and at any point and in particular already before " can be attached bending at oil-endangered places, without the appearance and use of such places disadvantageous influence.

Diese Aufgabe wird erfindungsgeraäß dadurch gelöst, daß in an sich bekannter Weise aus geeigneten Ausgangsstoffen Polyurethan-Hartechaum hergestellt wird und daß dieser Hartschaum granuliert und mit einem Bindemittel unter Verwendung von erhöhtem Druck und erhöhter Temperatur zu einem harten Gegenstand verpreßt wird. Vorzugsweise besitzt dieser Gegenstand die Form einer Platte oder eines Ähnlichen kubisch begrenzten Körpers. Das mit dem erfindungsgemäßen Material hergestellte Verfahren ist absolut staubfrei undThis object is achieved according to the invention in that in In a manner known per se, rigid polyurethane foam is produced from suitable starting materials and that this Rigid foam granulated and combined with a binder using elevated pressure and elevated temperature to one hard object is pressed. This object is preferably in the form of a plate or the like cubically bounded body. The method produced with the material according to the invention is absolutely dust-free and

saugt öl wie ein Fließblatt auf. DarUberhinaus ist es trittfest und daher begehbar und kann in Form von Bodenplatten verlegt werden. Das Material ist wasserabweisend, was insbesondere beim Einsatz von aus diesem Material hergestellten Platten sum Aufsaugen von auf Wasser schwimmendem öl besondere vorteilhaft ist. Das Material ist nämlich auch unsinkbar und nimmt daher das auf dem Wasser schwimmende öl an der Oberflache auf, wonach es einfach wieder ' aus dem nunmehr ölfreien Wasser herausgenommen werden kann» Schließlich besitzt eine nach dem erfindungsgemlßen Verfahren hergestellte Platte einen beachtlichen Wärme-soaks up oil like a sheet of bladder. Moreover, it is hard-wearing and therefore accessible and can be laid in the form of floor slabs. The material is water-repellent, what especially when using made from this material Plates to soak up oil floating on water is particularly advantageous. The material is namely also unsinkable and therefore absorbs the oil floating on the water on the surface, after which it simply returns' can be removed from the now oil-free water » Finally, has one according to the method of the invention produced plate a considerable heat

Utamwert und ist daher hervorragend für die Verwendung als Bauplatte geeignet. Sie kann bevorzugt in der Industrie an Maschinenplätzen eingesetzt werden, so daß von Maschinen wegspritzendes Ol von der Platte sofort aufgenommen werden kann. Da sie einen hohen Wärmedämmwert hat, dient sie gleichzeitig als Dämmplatte am Arbeitsplatz, um Fußkälte zu verhindern.Utamwert and is therefore excellent for use suitable as a building board. It can preferably be used in industry at machine stations, so that from Machine splashing oil from the plate is immediately absorbed can be. Since it has a high thermal insulation value, it also serves as an insulation board in the workplace To prevent cold feet.

Eine besondere Bedeutung hat die erfindungsgemäße Platte für den Bau von speziellen Kläranlagen und Filtereinrichtungen. Dabei kann die Platte in beliebigen Größen und Formen, beispielsweise auch als Würfel oder Kubus, eingesetzt werden.The plate according to the invention is of particular importance for the construction of special sewage treatment plants and filter facilities. The plate can be of any size and shape, for example, can also be used as a cube or cube.

Vorzugsweise wird der erfindungsgemäß verwendete Polyuretan -Hartschauin in an sich bekannter Weise aus Isocyanaten und Polyolen unter Hinzufügung geeigneter Stabilisatoren und Aktivatoren hergestellt. Das aus diesem Hartschaum hergestellte Granulat wird sodann bei einer bevorzugten Ausführungsform des erfindungagemäßen VerfahrensThe polyurethane used in the present invention is preferred -Hartschauin in a manner known per se from isocyanates and polyols with the addition of suitable stabilizers and activators. The one from this rigid foam granules produced are then used in a preferred embodiment of the method according to the invention

Besonders soll noch darauf hingewiesen werden, daß es möglich ist, das erfindungsgemäße Material mit verschiedenen ' Druckfestigkeiten herzustellen, wodurch sich jeweils weitgehend unterschiedliche technische Eigenschaften ergeben, wobei jedoch das ölaufsaugvermögen in bestimmten Druckfestigkeiten relativ bleibt. Als weiterer,Vorteil soll auch noch die besondere gute Verrottungsfestigkeit des erfindungsgemäßen Materials betont werden, so daß etwa von ihm aufgesaugtes Ol während eines eventuellen Verrottungsvor-" ganges nicht wieder freigesetzt werden kann.It should be pointed out in particular that it is possible to use the material according to the invention with different ' To produce compressive strengths, which result in largely different technical properties, however, the oil absorbency in certain compressive strengths remains relative. Another advantage should also be the particularly good resistance to rotting of the invention Material should be emphasized, so that any oil sucked up by him during a possible rotting pre- " ganges cannot be released again.
