Description
Kernöl für Gießereizwecke. Die Erfindung betrifft ein Kernöl für Gießereizwecke sowie Verfahren zur Herstellung desselben.Pumpkin seed oil for foundry purposes. The invention relates to a seed oil for foundry purposes and methods of making the same.
Bisher wurde als Kernöl, das zur Herstellung von Sandkernen für Gießereizwecke dient, mit gutem Erfolge in der Regel Leinöl verwendet.So far it has been used as a kernel oil for the production of sand cores for foundry purposes usually used with good results linseed oil.
Man hat auch bereits vorgeschlagen, an Stelle von Leinöl Fettpeche in Mischung mit Mineralölen zu verwenden.It has also already been suggested that fat pitch be used instead of linseed oil to be used in a mixture with mineral oils.
Es hat sich nun gezeigt, daß man an Stelle von Mineralölen auch Teeröle in Mischung mit Fettpechen mit Erfolg als Kernöl verwenden kann.It has now been shown that tar oils can also be used instead of mineral oils in a mixture with fat pitch can be used successfully as seed oil.
Teeröle bieten gegenüber Mineralölen den Vorzug, daß sie billiger und leichter zugänglich sind als diese. Außerdem verharzen Teeröle bei der hohen Backtemperatur und erteilen hierbei dem Sand eine gewisse Bindekraft und Festigkeit. Bei Mineralölen tritt diese Wirkung nicht ein, weil Mineralöle nicht so leicht verharzen wie Teeröle. Die Kerne, die mit Mineralöl hergestellt sind, springen daher leichter als solche, zu denen Teeröle verwendet worden sind.Tar oils have the advantage over mineral oils that they are cheaper and are more accessible than these. In addition, tar oils gum up at the high Baking temperature and give the sand a certain binding force and strength. This effect does not occur with mineral oils because mineral oils do not resinify so easily like tar oils. The kernels made with mineral oil therefore jump more easily than those to which tar oils have been used.
Nach der Erfindung werden daher als Lösung oder Emulgierungsmittel für Fettpeche Teeröle beliebiger Herkunft verwendet.According to the invention, therefore, as a solution or emulsifying agent used for fat pitch tar oils of any origin.
Der Mischung oder Lösung können auch Harze, Harzöle oder harzartige Körper zugesetzt «-erden, beispielsweise Kumaronharz. Unter Umständen ist auch der Zusatz von Emulsionsmitteln empfehlenswert, oder solche Stoffe, welche die Emulsionsfähigkeit erhöhen.The mixture or solution can also contain resins, rosin oils or resinous ones Body added to earth, for example coumarone resin. Under certain circumstances it is also The addition of emulsifying agents is recommended, or substances that make the product emulsifiable raise.
Als besonders zweckmäßig hat sich eine Mischung von zwei Teilen Stearinpech mit ein bis zwei Teilen Kumaronharz und etwa drei bis fünf Teilen Teeröl erwiesen.A mixture of two parts of stearic pitch has proven to be particularly useful with one to two parts of coumarone resin and about three to five parts of tar oil.
Ausführungsbeispiele i. 5o kg Stearinpech werden in 5o kg Teeröl ausgelöst. Diese Lösung wird dann in dem gewünschten Prozentsatz der Sandmasse zugesetzt. Im übrigen verfährt man genau wie bei Verwendung von Leinöl.Embodiments i. 50 kg of stearic pitch are dissolved in 50 kg of tar oil. This solution is then added to the sand mass in the desired percentage. in the The rest of the process is exactly the same as when using linseed oil.
2. 3o kg Stearinpech und 25 g zähflüssiges Kumaronharz werden in 50 kg Teeröl gelöst. ,2. 30 kg of stearic pitch and 25 g of viscous coumarone resin are dissolved in 50 kg of tar oil. ,
