Description

Wärmebeständiges, öl- und fettfreies, wasserlösliches Phosphat und Borat enthaltendes Schmiermittel Zusatz zum Patent: 1050 486 Gegenstand des Hauptpatents 1050 486 ist die Verwendung eines bei der Temperatur von Lager-oder Gleitstellen geschmolzenen Gemischs eines Alkalitetraborats mit einem Meta-, Ortho- oder Pyrophosphat eines Alkalimetalls als Schmiermittel zum Schmieren von hohen Temperaturen ausgesetzten Lager- und Gleitstellen von Metallteilen, insbesondere von warm zu verformenden metallischen Werkstücken.Heat-resistant, oil- and fat-free, water-soluble phosphate and Borate-containing lubricant Patent addendum: 1050 486 Subject matter of the main patent 1050 486 is the use of one at the temperature of bearing or sliding points molten mixture of an alkali tetraborate with a meta-, ortho- or pyrophosphate an alkali metal as a lubricant for lubricating exposed to high temperatures Bearing and sliding points of metal parts, in particular of those that are hot to be deformed metallic workpieces.

Gemische der genannten Zusammensetzung beginnen bereits bei einer verhältnismäßig niedrigen, weit unter dem Schmelzpunkt ihrer Bestandteile liegenden Temperatur (z. B. bei 300° C) zu erweichen, bilden also eutektoide Schmelzen, die bei weiterer Erwärmung vom zähflüssigen in den niederviskosen Zustand übergehen und innerhalb eines großen Temperaturbereichs, der bis 1000° C und darüber reicht, beständig sind und schmierend wirken. Die Gemische können in Form einer Schmelze auf die zu schmierende Fläche aufgebracht, aber auch als trockenes Pulver oder in wäßriger Lösung aufgetragen werden, wobei im letzteren Fall das Wasser nur als Lösungsmittel und Träger dient und eine besonders schnelle und gleichmäßige Verteilung des Schmiermittels begünstigt. Unabhängig von der Art des Auftragens bildet das Gemisch - beim Auftragen in Lösung nach Verdampfen des Lösungsmittels - auf dem heißen, gegebenenfalls gemeinsam mit ihm erhitzten Werkstück eine eutektoide Schmelze, die die benutzte Fläche zunächst entzundert und alsdann auf dem blanken Metall einen gleichmäßig und einwandfrei haftenden Schmiermittelfilm bildet, der bis zu hohen Temperaturen von 1000° C und mehr beständig ist.Mixtures of the composition mentioned start with one relatively low, well below the melting point of their constituents Temperature (e.g. at 300 ° C) to soften, so form eutectoid melts, the with further heating change from the viscous to the low-viscosity state and within a wide temperature range up to 1000 ° C and above, are stable and have a lubricating effect. The mixtures can be in the form of a melt Applied to the surface to be lubricated, but also as a dry powder or in aqueous solution can be applied, in the latter case the water only as a solvent and carrier and a particularly fast and even distribution of the lubricant favored. Regardless of the type of application, the mixture forms - when applied in solution after evaporation of the solvent - on the hot, optionally together with it heated workpiece a eutectoid melt, which the used surface initially descaled and then on the bare metal one evenly and flawlessly adhesive film of lubricant forms, which can up to high temperatures of 1000 ° C and is more permanent.

Es wurde nun gefunden, daß sich für die im Hauptpatent genannten Verwendungszwecke, vor allem also zum Schmieren von hohen Temperaturen ausgesetzten Lager- und Gleitstellen von Metallteilen ein Alkaliphosphat enthaltendes Salzgemisch noch besser eignet, in dem das Alkalitetraborat teilweise durch das Sulfat oder Chlorid eines Alkalimetalls oder das Magnesium ersetzt ist. Auch derart zusammengesetzte Salzgemische, die bei Erwärmung auf eine unterhalb der Anwendungstemperatur liegende Temperatur erweichen, im wirksamen Temperaturbereich also schmelzflüssig sind, bilden auf der jeweiligen Unterlage einen geschlossenen und gut haftenden Film und wirken zunderlösend.It has now been found that for the purposes mentioned in the main patent, especially for the lubrication of bearings and sliding points exposed to high temperatures of metal parts, a salt mixture containing alkali phosphate is even more suitable, in which the alkali tetraborate is partially replaced by the sulfate or chloride of an alkali metal or the magnesium is replaced. Also such a composite salt mixture, which at Soften the heating to a temperature below the application temperature, are therefore molten in the effective temperature range, form on the respective Underlay a closed and well-adhering film and have a scale-dissolving effect.

Demgemäß wird erfindungsgemäß für die Verwendung als Schmiermittel nach dem Patent 1050486 ein Salzgemisch vorgeschlagen, worin das Alkalitetraborat teilweise durch das Sulfat oder Chlorid eines Alkalimetalls oder des Magnesiums ersetzt ist. Die erfindungsgemäße Verwendung von Schmelzen der genannten Salzgemische als Schmiermittel ist nicht nur auf die Warmverarbeitung von Metallen beschränkt, sondern beispielsweise auch bei von im Betrieb hohen Temperaturen ausgesetzten Maschinen-und Vorrichtungsteilen möglich.Accordingly, the present invention is for use as a lubricant proposed a salt mixture according to patent 1050486, wherein the alkali tetraborate partly by the sulfate or chloride of an alkali metal or magnesium is replaced. The use according to the invention of melts of the salt mixtures mentioned as a lubricant is not limited to the hot processing of metals, but also, for example, in the case of machines and equipment exposed to high temperatures during operation Device parts possible.

Die Zeichnung gibt ein Erweichungsdiagramm für unter die Erfindung fallende Salzgemische dar, in denen das Natriumtetraborat jeweils zur Hälfte durch Natriumsulfat ersetzt ist. Aus ihm ist zu ersehen, daß diese Mischungen eutektoide Schmelzen bilden, deren Erweichung je nach Mischungsverhältnis schon bei etwa 420° C beginnt, während bei anderen Zusammensetzungen die Erweichung erst bei höheren Temperaturen einsetzt. Es ist also leicht möglich, durch geeignete Auswahl der Komponenten und durch Änderung der prozentualen Zusammensetzung das Schmiermittel für die vorgesehene Verwendung entsprechend anzupassen.The drawing gives a softening diagram for under the invention falling salt mixtures, in which the sodium tetraborate is half through Sodium sulfate is replaced. It can be seen from it that these mixtures are eutectoid Melts form, their softening, depending on the mixing ratio, at around 420 ° C begins, while with other compositions the softening only begins at higher ones Temperatures sets in. It is therefore easily possible through a suitable selection of the components and by changing the percentage composition the lubricant for the intended Adjust usage accordingly.

Wie Versuche ergeben haben, sind die Schmiereigenschaften der hier vorgeschlagenen Gemische, vorzugsweise der Alkalimetallsulfat-Phosphat-Gemische, besser als die der Gemische nach dem Hauptpatent, und zwar besonders bei der Verformung von legierten Stählen. Außerdem sind die Alkalimetall- und Magnesiumsulfate und -chloride wesentlich billiger als Alkalitetraborate.As tests have shown, the lubricating properties are here proposed mixtures, preferably the alkali metal sulfate-phosphate mixtures, better than that of the mixtures according to the main patent, especially when it comes to deformation of alloy steels. Also, the alkali metal and magnesium sulfates and -chloride much cheaper than alkali tetraborate.
