Description
Sehneid- und Kühldispersion. Schneid- und Kühldispersionen werden im allgemeinen unter Verwendung von Ölen und Fetten hergestellt. Es wurde nun gefunden, dass als derartige Dispersionen, wie sie bei der spanabhebenden oder spanlosen Formung Verwendung finden, sich besonders solche eignen, bei denen in einer Wasserglaslösung Graphit fein verteilt ist. Die Schutzwirkung beruht darauf, dass es gelingt, den feinverteil ten Graphit auch in einer verdünnten Was serglaslösung im Schwebezustand zu erhal ten.
Die Wasserglaslösung wirkt für den kol loidalen Graphit als Träger und ermöglicht die Ausbildung eines feinen Schutz- bezw. Schmierfilmes.
Vorteilhaft wird Wasserglas in einem Anteil angewendet, der das Fünf- bis Sechs fache des Graphitzusatzes beträgt. Die Her stellung der Dispersion erfolgt zweckmässig unter Erwärmung, wobei noch ein Dispergie- rungsmittel zugesetzt werden kann. Hierfär hat sich zum Beispiel eine geringe Menge von Mineralöl als besonders geeignet erwiesen. Auch kann der Zusatz eines Wasserenthär- tungsmittels erfolgen.
<I>Ausführungsbeispiel:</I> 90 g handelsübliche Natronwasserglas- lösung werden in einem Rührwerk unter Zu satz von etwa 15 bis 20 g Graphit auf 90 erhitzt, wobei 5 g Mineralöl bezw. ein an derer fetthaltiger Emulgator zugesetzt wer den kann.
Nach Herstellung der Dispersion wird ein an sich bekanntes Wasserenthärtungsmittel zugesetzt.
Auf diese Weise ergibt sich ein Konzen trat, das sofort gebrauchsfertig ist und das je nach dem Anwendungszweck ohne Schwie rigkeiten beliebig mit Wasser verdünnt wer den kann. Die Handhabung ist etwa die glei che wie bei den bekannten Bohr- und Schneid emulsionen, doch ergibt sich eine bedeutende Ersparnis an öligen und fettigen Anteilen. Die Dispersion zeigt neben der Schmierwir kung auch eine hohe Kühlwirkung.
Cutting and cooling dispersion. Cutting and cooling dispersions are generally made using oils and fats. It has now been found that dispersions of this type, such as those used in machining or non-cutting shaping, are particularly suitable in which graphite is finely distributed in a waterglass solution. The protective effect is based on the fact that it is possible to keep the finely divided graphite in a suspended state even in a dilute waterglass solution.
The water glass solution acts as a carrier for the colloidal graphite and enables the formation of a fine protective or Lubricating film.
Water glass is advantageously used in a proportion that is five to six times the amount of graphite added. The dispersion is expediently prepared with heating, it being possible to add a dispersing agent. A small amount of mineral oil, for example, has proven particularly suitable for this purpose. A water softener can also be added.
<I> Exemplary embodiment: </I> 90 g of commercially available soda waterglass solution are heated to 90 in a stirrer with the addition of about 15 to 20 g of graphite, with 5 g of mineral oil respectively. another fat-containing emulsifier can be added.
After the dispersion has been prepared, a water softener known per se is added.
In this way, the result is a concentrate that is immediately ready for use and that, depending on the intended use, can be diluted with water as desired without difficulty. The handling is about the same as with the known drilling and cutting emulsions, but there is a significant saving in oily and greasy components. In addition to the lubricating effect, the dispersion also has a high cooling effect.
