Description

Schmier- und Gleitmittel Zusatz zur Patentanmeldung B 31055 IVc / 23 c Gegenstand derHauptpatentanmeldungB 31055 IVc/23c ist die Verwendung von in bekannter Weise aus Ammoniumsulfomolybdaten oder Ammoniumsulfowolframaten erhältlichem Molybdändisulfid oder Wolframdisulfid als Schmier- und Gleitmittel.Lubricants and lubricants addendum to patent application B 31055 IVc / 23 c The subject of the main patent application B 31055 IVc / 23c is the use of in known manner from ammonium sulfomolybdates or ammonium sulfotungstates obtainable Molybdenum disulfide or tungsten disulfide as a lubricant and lubricant.

Es wurde gefunden, daß man besonders gute Schmier-und Gleitmittel erhält, wenn man ein Molybdändisulfid oder Wolframdisulfid gemäß der Hauptpatentanmeldung B 31055 I V c/23 c in Mischung mit einem natürlichen Molybdändisulfid verwendet, wobei das synthetische Disulfid in einer Korngröße unterhalb 40,u und das natürliche Molybdändisulfid in einer Körnung zwischen 40 und 80,u vorliegen muß.It has been found that particularly good lubricants and lubricants are obtained if a molybdenum disulfide or tungsten disulfide according to the main patent application B 31055 IV c / 23 c is used in a mixture with a natural molybdenum disulfide, the synthetic disulfide having a grain size below 40, u and the natural molybdenum disulphide must be present in a grain size between 40 and 80 u.

Die nach der Hauptpatentanmeldung B 31055IV c/23 c als Schmier- und Gleitmittel verwendeten Molybdän- und Wolframdisulfide werden in bekannter Weise, z. B. aus durch Behandlung wäßriger Lösungen von Ammoniummolybdat bzw. Ammoniumwolframat mit Schwefelwasserstoff oder geeigneten Sulfiden erhaltenen Ammoniumsulfomolybdaten bzw. -wolframaten durch deren Erhitzen auf Temperaturen von oberhalb 250°, insbesondere 400 bis 600°, in einem Gasstrom von z. B. Stickstoff, Ammoniak, Kohlendioxyd, insbesondere aber Wasserstoff, erhalten.According to the main patent application B 31055IV c / 23 c as lubricating and Molybdenum and tungsten disulfides used in lubricants are used in a known manner, z. B. from by treating aqueous solutions of ammonium molybdate or ammonium tungstate ammonium sulfomolybdates obtained with hydrogen sulfide or suitable sulfides or tungstates by heating them to temperatures above 250 °, in particular 400 to 600 °, in a gas stream of z. B. nitrogen, ammonia, carbon dioxide, in particular but get hydrogen.

Diese synthetischen Disulfide werden durch Zerkleinerung in an sich bekannten Mahlvorrichtungen auf eine Korngröße von unterhalb 40,u, zweckmäßig zwischen 1 und 30,u, vorteilhaft 1 und 10,u, gebracht, während für das natürliche Molybdändisulfid im allgemeinen Korngrößen zwischen 40 und 80,u, insbesondere 50 und 70,u gewählt werden. Nur bei Mischungen der beiden Komponenten in den genannten Korngrößen wird die verbesserte Schmierwirkung erzielt. Die synthetischen Disulfide werden dem natürlichen Molybdändisulfid in einer Menge von 5 bis 50 Gewichtsprozent, vorteilhaft von 15 bis 40 Gewichtsprozent, zugegeben.These synthetic disulfides are broken down by crushing in themselves known grinding devices to a grain size of below 40, u, expediently between 1 and 30, u, advantageously 1 and 10, u, while for the natural molybdenum disulfide generally grain sizes between 40 and 80, u, in particular 50 and 70, u are selected will. Only when the two components are mixed in the specified grain sizes the improved lubricating effect achieved. The synthetic disulfides become the natural ones Molybdenum disulfide in an amount of 5 to 50 percent by weight, advantageously 15 up to 40 percent by weight, added.

Diese Gemische können gegebenenfalls auch unter Zusatz von Graphit und/oder festen hochmolekularen temperaturbeständigen Polymerisaten wie Polyvinylchlorid, Polyamiden, polymerisierten Olefinen, Harnstoffpolymerisaten als Schmier- und Gleitmittel verwendet werden.These mixtures can optionally also with the addition of graphite and / or solid, high molecular weight, temperature-resistant polymers such as polyvinyl chloride, Polyamides, polymerized olefins, urea polymers as lubricants and lubricants be used.

Beispiel In eine wäßrige Lösung, die 200/, Molybdänsäure und 15 % Ammoniak enthält, wird bei 50° Schwefelwasserstoff bis zur Sättigung eingeleitet. Die Lösung wird anschließend auf Zimmertemperatur abgekühlt. Die dabei ausfallenden rotvioletten Nadeln des Ammoniumsulfomolybdats werden abgesaugt, mit Stickstoff abgeblasen, langsam getrocknet und schließlich im trockenen Wasserstoffstrom bei 600° zu Molybdändisulfid zersetzt. Dieses Disulfid wird dann auf eine Körnung von 1 bis 5,u gemahlen.EXAMPLE In an aqueous solution containing 200 % molybdic acid and 15% ammonia, hydrogen sulphide is passed at 50 ° until it is saturated. The solution is then cooled to room temperature. The red-violet needles of ammonium sulfomolybdate which precipitate out are filtered off with suction, blown off with nitrogen, slowly dried and finally decomposed in a stream of dry hydrogen at 600 ° to form molybdenum disulfide. This disulfide is then ground to a grain size of 1 to 5 microns.

Das so erzeugte Pulver wird in einer Menge von 25 Gewichtsprozent einem natürlichen Molybdändisulfid von einer Körnung von 50 bis 70,u zugegeben.The powder thus produced is used in an amount of 25 percent by weight a natural molybdenum disulphide with a grain size of 50 to 70 µ added.

In der Almen-Wieland-Maschine ergibt die Mischung eine Endbelastung von 2300 kg bei 350 kg Reibungskraft. Bei derselben Reibungskraft verträgt das natürliche Molybdändisulfid für sich allein nur eine Belastung von 2000 kg. Die Mischung ermöglicht also eine höhere Belastung und gibt einen niederen Reibungskoeffizienten von 0,152 gegen 0,175.In the Almen-Wieland machine, the mixture results in a final load of 2300 kg at 350 kg friction force. The natural can tolerate the same frictional force Molybdenum disulphide alone only carries a load of 2000 kg. The mix makes it possible thus a higher load and gives a lower coefficient of friction of 0.152 against 0.175.
