Abstract

The granulate comprises comminuted (hard foam), polyurethane resin, and can be used to remove oil from streets or floors, or break oil/water emulsions with subsequent binding of the oil component.

Description

verfahren zum Binden von Öl oder ähnlichen Stoffen" Die Erfindung bezieht sich auf ein Verfahren zum Binden von verschüttetem oder ausgelaufenem Öl auf Straßen oder Fabrikböden sowie auf eine Möglichkeit zum Beseitigen von in Wasserläufe eingedrungenem Öl bzw. zum Trennen von Öl- Wasseremulsionen mit gleichzeitigem Abbinden der Ölbestandteile durch ausfällbare Feststoffe. method for binding oil or similar substances "The invention refers to a method of binding spilled or leaked oil on streets or factory floors, as well as a way of eliminating in watercourses penetrated oil or to separate oil-water emulsions with simultaneous setting the oil components through precipitable solids.

Insbesondere für den zuletzt genannten Anwendungsfall ist ein Bindemittel erforderlich, das wasserabweisend ist, sich also nicht mit Wasser vollsaugen kann sondern seine volle Saugfähigkeit für das Aufnehmen der ölhaltigen Bestandteile beibehält.A binder is particularly useful for the last-mentioned application required, which is water-repellent, so cannot soak up with water but its full absorbency for the absorption of the oil-containing components maintains.

Diese Aufgabe wird gemäß der vorliegenden Erfindung dadurch gelöst, daß auf oder in die Flüssigkeit ein hochporöses, wasserabweisendes Granulat auf- bzw. eingebracht wird, wobei dieses Granulat aus nach dem Aushärten zerkleinertem PUR-Hartschaum besteht. Der wesentliche Vorteil dieses Granulats liegt darin, daß er völlig wasserabstoßend ist, ölige Bestandteile hingegen schwammartig aufsaugt.According to the present invention, this object is achieved by that on or in the liquid a highly porous, water-repellent granulate or is introduced, these granules being made from comminuted after hardening PUR rigid foam. The main advantage of these granules is that it is completely water-repellent, but absorbs oily components like a sponge.

Ein weiterer Vorteil ist noch darin zu erblicken, daß die bei der Herstellung von PUR-Formkörpern anfallenden Abfälle, insbesondere die Angußtrichter, deren Beseitigung bisher Schwierigkeiten bereitete, weil das Material weder verrottet noch in einfacher Weise verbrennt, bei Anwendung der vorliegenden Erfindung zu einem Granulat verarbeitet werden kann, welches nach seiner Verwendung als Olbindemittel in einfacher Weise und fast rückstandsfrei verbrennt.Another advantage can be seen in the fact that the Manufacture of PUR moldings incurring waste, in particular the sprue funnel, the elimination of which has previously caused difficulties because the material does not rot still burns in a simple manner when applied the present Invention can be processed into a granulate, which after its use burns as an oil binder in a simple manner and with almost no residue.
