Description

Schmiermittel Konsistente Schmiermittel werden in der Regel aus verseiften Fetten und Mineral- oder synthetischen Ölen hergestellt. Es wurde auch schon vorgeschlagen, Gelfette herzustellen durch Zusätze von relativ kleinen :Mengen hochdisperser Kieselsäure zu Ölprodukten. Von solcher durch Zersetzung von flüchtigen Siliciumverbindungen, insbesondere Siliciumtetrachlorid, in der Gasphase in einer Flamme vermittels oxydierender oder hydrolysierender Mittel unter rascher Entfernung des festen Reaktionsproduktes aus der Flamme und Abkühlung auf Temperaturen oberhalb des Taupunktes der leicht kondensierbaren Reaktionsprodukte gewonnener Kieselsäure mit Teilchengrößen von unter 50 Hit genügen schon Zusätze von wenigen Prozenten, um dünnflüssige öle in steife Gallerten umzuwandeln.Lubricants Consistent lubricants are usually made from saponified Fats and mineral or synthetic oils. It has also been suggested Manufacture gel fats by adding relatively small amounts of highly dispersed silica to oil products. Of those by the decomposition of volatile silicon compounds, in particular silicon tetrachloride, oxidizing in the gas phase in a flame or hydrolyzing agents with rapid removal of the solid reaction product from the flame and cooling to temperatures above the dew point of the easy condensable reaction products obtained from silica with particle sizes of below 50 Hit, additions of just a few percent are sufficient to convert low-viscosity oils into to convert stiff jelly.

Es wurde nun gefunden, daß man auch durch Zusätze von sehr hochdispersen Rußsorten zu Ölen steife konsistente Schmiermittel herstellen kann. Insbesondere haben sich hierzu solche Rußsorten als brauchbar erwiesen, deren Teilchengröße unter 2o yft, vorzugsweise unter to H,H liegt.It has now been found that stiff, consistent lubricants can also be produced by adding very highly dispersed types of carbon black to oils. In particular, those types of carbon black have proven to be useful for this purpose, the particle size of which is below 20 yft, preferably below 1 to H, H.

Geeignet sind z. B. die bei der Erdgasverbrennung bei hohem Abbrand gewinnbaren höchstdispersen Rußsorten. Brauchbar sind auch solche hochdispersen Rußsorten, die zur Beeinflussung der Benetzbarkeit einer Nachbehandlung durch Glühen oder mit oxydierenden Mitteln, wie Salpetersäure oder Ozon, unterworfen waren.Suitable are e.g. B. the natural gas combustion with high burn-up recoverable highly dispersed types of carbon black. Such highly disperse ones can also be used Types of carbon black used to influence the wettability of an after-treatment by annealing or with oxidizing agents such as nitric acid or ozone.

Die Gelbildung wird außer von der Rußsorte von der chemischen Struktur der verwendeten Ausgangsöle beeinflu:ßt. Diese Öle können bevorzugt polare oder unpolare Kohlenwasserstoffe enthalten. In manchen Fällen ist die Anwesenheit größerer Anteile von verzweigten Kohlenwasserstoffen erwünscht, darunter auch von solchen mit relativ langen Kohlenstoffketten. Die Konsistenz derartiger Rußölgemische kann ferner beeinflußt werden durch die Benetzbarkeit der jeweiligen Rußsorte und/oder durch entsprechende Netzmittelzusätze.In addition to the type of carbon black, the formation of the gel depends on the chemical structure of the starting oils used. These oils can preferably be polar or Contain non-polar hydrocarbons. In some cases the presence is greater Parts of branched hydrocarbons desirable, including some with relatively long carbon chains. The consistency of such carbon black oil mixtures can are also influenced by the wettability of the respective type of carbon black and / or by adding appropriate wetting agents.

Besonders vorteilhaft ist die weitgehende Unabhängigkeit der Konsistenz solcher verdickter Öle oder Starrschmieren von der Temperatur. Es ist nach dem erfindungsgemäßen Verfahren, besonders bei der Verwendung tiefstockender Öle, möglich, sowohl gegen tiefe als gleichzeitig gegenüber hohen Temperaturen beständige konsistente Schmiermittel herzustellen.The extensive independence of the consistency is particularly advantageous such thickened oils or rigid smear from temperature. It is according to the invention Procedure, especially when using deep stock oils, possible both against deep and consistent lubricants that are also resistant to high temperatures to manufacture.

Es ist möglich, bei der mechanischen Anreibung derartiger Rußölgemische, die auf Walzenstühlen oder Farbreibmühlen erfolgen kann, Benetzungsmittel und/oder Dispergiermittel zuzusetzen. Auch die sonst übliche Mitverwendung von Alterungsschutzmitteln, hochmolekularen Verdickungsmitteln, Fetten, Wachsen, fettsauren Salzen, Graphit, Schutzkolloiden und Stabilisatoren ist unter Umständen empfehlenswert. Es ist ferner möglich, Gemische von hochdispersen Rußsorten mit hochdispersen Kieselsäuren und/oder anderen hochdispersen Stoffen zu verwenden. Das Ausmaß der verdickenden Wirkung ist aus der Nebeneinanderstellung folgender Angaben deutlich erkennbar: Ein zur Verdickung verwendetes Spindelöl besitzt eine Viskosität von 36 cP bei 2o°. Nach dem Zusatz von etwa 5 bis 6% einer höchstdispersen erfindungsgemäßen Rußsorte bildet das entstandene Gemisch eine steife standfeste Paste.It is possible during the mechanical grinding of such soot oil mixtures, which can be done on roller mills or color grinding mills, wetting agents and / or Add dispersant. Also the otherwise common use of anti-aging agents, high molecular weight thickeners, fats, waxes, fatty acid salts, graphite, Protective colloids and stabilizers may be recommended. It is further possible, mixtures of highly dispersed types of carbon black with highly dispersed silicas and / or to use other highly dispersed substances. The extent of the thickening effect can be clearly seen from the juxtaposition of the following information: A for Spindle oil used for thickening has a viscosity of 36 cP at 20 °. To the addition of about 5 to 6% of a highly dispersed type of carbon black according to the invention the resulting mixture is a stiff, firm paste.
