Description

Verfahren zur Herstellung von Kernölen für Gießereizwecke. Die Erfindung betrifft ein Verfahren zur Herstellung von Kernöl für Gießereizwecke.Process for the production of seed oils for foundry purposes. The invention relates to a process for the production of seed oil for foundry purposes.

Als Kernöl zur Herstellung von Sandkernen für Gießereizwecke wurde bisher fast ausschließlich Leinöl verwendet.As a seed oil for the production of sand cores for foundry purposes was Until now, linseed oil has been used almost exclusively.

Man hat auch bereits vorgeschlagen, als Bindemittel für Kern- und Formsand, Pech, Teer oder Petroleum zu verwenden.It has also already been proposed as a binder for core and Use molding sand, pitch, tar, or kerosene.

Auch die Verwendung von Fettpech in Mischung mit Mineralöl oder mit Teeröl bilden bereits den Gegenstand älterer Verfahren.Also the use of fat pitch mixed with mineral oil or with Tar oil are already the subject of older processes.

Versuche haberiFnun hergeben, daß sich mit besonders gutem Erfolge oxydierte Teeröle als Kernöl verwenden lassen: Oxydierte Teeröle haben die Eigenschaft, sich mit Formsand leichter innig mischen zu lassen als Pech und Teer, so daß man ohne Hinzufügung anderer Stoffe vollkommen homogene Mischungen erhält, die in ihrer Wirkung den Mischungen mit Leinöl vollkommen gleichkommen.Attempts have now given that up with particularly good results Have oxidized tar oils used as seed oil: Oxidized tar oils have the property to mix more easily with molding sand than pitch and tar, so that one without the addition of other substances completely homogeneous mixtures obtained in their Effect exactly the same as the mixtures with linseed oil.

Außerdem aber verharzen Teeröle durch die Oxydation im gewissen Umfang und erhalten daher eine bessere Bindekraft als nicht oxydierte Öle dieser Art. Infolgedessen springen die Kerne, die mit oxydiertem Teeröl hergestellt worden sind, viel weniger leicht als bei Benutzung der bisher bekannten Ersatzmittel für Leinöl.In addition, tar oils gum up to a certain extent due to oxidation and therefore obtain better binding strength than unoxidized oils of this type. As a result the kernels made with oxidized tar oil jump much less easier than when using the previously known substitutes for linseed oil.

Zur Ausführung des Verfahrens verfährt man in der Weise, daß Teeröl beliebiger Herkunft mit Luft, Sauerstoff oder anderen Oxydationsmitteln so lange behandelt wird, bis ein zähflüssiger bis harziger Körper entsteht.To carry out the process one proceeds in such a way that tar oil of any origin with air, oxygen or other oxidizing agents for so long is treated until a viscous to resinous body is formed.

Den oxydierten Teerölen können auch Peche beliebiger ,Herkunft zugesetzt werden.Pitch of any origin can also be added to the oxidized tar oils will.

Vor der Oxydation kann man den Teerölen auch noch andere Öle zusetzen, die leichter oxydierbar sind, insbesondere fette Öle, wie Leinöl, Maisöl und Trane. Diese Öle wirken dann gewissermaßen als Katalysator, indem die Oxydation des Gesamtproduktes leichter und schneller vor sich geht.Before the oxidation, other oils can also be added to the tar oils, which are more easily oxidized, especially fatty oils such as linseed oil, corn oil and trane. These oils then act as a kind of catalyst by oxidizing the overall product is easier and faster.
