Description

Druckfeste Schmieröle, insbesondere auf Mineralölbasis Die Erfindung betrifft die Zusammensetzung druckfester, mit Wasser emulgierter Schmieröle, insbesondere auf Mineralölbasis.Pressure-resistant lubricating oils, especially those based on mineral oil. The invention relates in particular to the composition of pressure-resistant lubricating oils emulsified with water based on mineral oil.

Es ist bekannt, daß viele Mineralschmieröle eine geringe bis mäßige Druckfestigkeit des Ölfilms ergeben. Zwecks Steigerung der Druckfestigkeit hat man dem Mineralschmieröl bisher Zusätze verschiedener Art einzeln oder. zu mehreren beigegeben, wie Bleiseifen oder organische Schwefel-, Halogen- und Phosphorverbindungen. Die so behandelten Schmieröle rufen im Betriebe häufig Korrosionen an den geschmierten Aggregaten hervor und wirken großenteils auf Gummi erhärtend.It is known that many mineral lubricating oils have a low to moderate Result in compressive strength of the oil film. In order to increase the compressive strength one has The mineral lubricating oil so far additives of various kinds individually or. to several added, such as lead soaps or organic sulfur, halogen and phosphorus compounds. The lubricating oils treated in this way often cause corrosion in the company Aggregates and have a largely hardening effect on rubber.

Auf Grund der Erfindung wird die Druckfestigkeit des Ölfilms von Mineralschmierölen ohne solche chemische Zusätze erhöht, indem das Öl mit 0,5 Volumprozent Wasser emulgiert wird. Bei einer besonderen Ausführungsweise der Erfindung wird gleichzeitig mit dem Wasser Luft in das Öl eingebracht. Ferner ist vorgesehen, daß dem Wasser stabilisierende und rostschützende Zusätze beigegeben werden. Das Wasser wird zweckmäßig mittels Ultraschalls in das Öl eingebracht.Based on the invention, the compressive strength of the oil film of mineral lubricating oils without such chemical additives is increased by emulsifying the oil with 0.5 percent by volume of water. In a particular embodiment of the invention, air is introduced into the oil at the same time as the water. It is also provided that stabilizing and rust-preventing additives are added to the water. The water is expediently introduced into the oil by means of ultrasound.

Bei den bekannten Schmierölen mit einem Wassergehalt von o,z bis o,5 °/o ist das Wasser, das mit dem Schmieröl nicht emulgiert ist, als unerwünschte Verunreinigung anzusehen.In the case of the known lubricating oils with a water content of o, z to o, 5 ° / o the water that is not emulsified with the lubricating oil is considered undesirable To look at pollution.

Es sind Schmieröl-Wasser-Emulsionen bekannt, die neben Wasser Stoffe, wie Kalk, Pottasche, Seife, Wachs u. dgl. enthalten oder bis zur Hälfte und mehr aus Wasser bestehen. Diese Emulsionen stellen natürlich nur ganz speziell verwendbare Schmiermittel dar, die als Motorenöl kaum und als Getriebeöl überhaupt nicht in Betracht kommen.Lubricating oil-water emulsions are known which, in addition to water, contain substances such as lime, potash, soap, wax and the like. Contain up to half or more consist of water. Of course, these emulsions are only particularly useful Lubricants that are hardly used as engine oil and not at all as gear oil Come into consideration.

Auf Grund der Erfindung wurden bei den handelsüblichen Motorenölen Shell X, Arctic und Veedol HD g02 auf der Ahnen-Wieland-Prüfmaschine Vergleichswerte gemäß folgender Aufstellung erhalten: A = Ausgangszustand, E = emulgiert (o,5 Volumprozent Wasser) Druckfestigkeit in kg/"",. bei Normal- temperatur bei 75 bis 9o ° C A- I E A I E - Shell X ........... 300 735' i80 63o Arctic ............ 240 io8o 18o 66o Veedol HD g02 .... 36o 1050 18o goo Demgegenüber beträgt z. B. die Druckfestigkeit des Höchstdruck- (Hypoid) Öles Esso XP go, gemessen auf der Almen-Wieland-Ölprüfmaschine bei Normaltemperatur 110o kg[cm2.On the basis of the invention, comparative values were obtained with the commercially available engine oils Shell X, Arctic and Veedol HD g02 on the Ahnen-Wieland testing machine according to the following table: A = initial state, E = emulsified (0.5 volume percent water) Compressive strength in kg / "" ,. at normal temperature at 75 to 9o ° C A - IE AIE - Shell X ........... 300 735 'i80 63o Arctic ............ 240 io8o 18o 66o Veedol HD g02 .... 36o 1050 18o goo In contrast, z. B. the compressive strength of the maximum pressure (hypoid) oil Esso XP go, measured on the Almen-Wieland oil testing machine at normal temperature 110o kg [cm2.

Für die Druckfestigkeit des Ölfilms der drei obengenannten Öle ergeben sich demnach folgende Verhältniszahlen Normal- temperatur 75 E bezogen auf die Druckfestigkeit im Ausgangszustand A E A bei Normal- b# l 9o ° `1 tempe- 75 C ratur - x ShelI X ...... i 2,4 O,6 ?',i 3,5 Arctic ....... 1 4,5 0,75 2,75 3,75 Veedol HD g02 1 7,9 o,5 2,5 5,0 Unter diesen Umständen ist es z. B: möglich, ein solches Öl während der Einlaufperiode von Getrieben an Stelle von Ölen mit Hochdruckzusätzen zu verwenden, wobei der ungünstige Einfuß der Hochdruckzusätze auf die Getriebewerkstoffe ausgeschaltet wird.The following ratios result for the compressive strength of the oil film of the three above-mentioned oils normal temperature 7 5 E. based on the Compressive strength in Initial state AEA at Normal- b # l 9o ° `1 tempe- 75 C rature - x ShelI X ...... i 2.4 O, 6 ? ', I 3.5 Arctic ....... 1 4.5 0.75 2.75 3.75 Veedol HD g02 1 7.9 o, 5 2.5 5.0 Under these circumstances it is e.g. B: possible to use such an oil during the running-in period of gearboxes instead of oils with high pressure additives, whereby the unfavorable influence of high pressure additives on the gearbox materials is eliminated.

Ferner kann die Wirtschaftlichkeit der synthetischen Ölgewinnung auf Grund der Erfindung gesteigert werden, da nunmehr die großenteils anfallenden Öle geringer Druckfestigkeit besser als Schmieröle verwertet werden können.It can also increase the economics of synthetic oil production Due to the invention are increased, since now the largely resulting oils lower compressive strength can be better recycled than lubricating oils.
