Description
Diese Erfindung betrifft eine Schmierölzusammensetzung, insbesondere eine Schmierölzusammensetzung mit hervorragenden reibungsvermindernden Eigenschaften unter unterschiedlichen Gleitbedingungen, die auch den Beibehalt dieser reibungsvermindernden Eigenschaften über einen längeren Zeitraum selbst in Gegenwart von Stickoxidgas ermöglicht, und insbesondere eine Schmierölzusammensetzung, die als Schmieröl für Verbrennungsmotoren geeignet ist.This invention relates to a lubricating oil composition, in particular, to a lubricating oil composition having excellent friction-reducing properties under various sliding conditions, which also enables the maintenance of these friction-reducing properties over a prolonged period of time even in the presence of nitrogen oxide gas, and in particular to a lubricating oil composition suitable as a lubricating oil for internal combustion engines.
In Kraftübertragungsgeräten wie Verbrennungsmotoren, Automatikgetrieben, Stoßdämpfern und Kraftsteuerungssystemen wird Schmieröl verwendet, um ihren Betrieb reibungsärmer zu gestalten. Insbesondere Schmieröl für einen Verbrennungsmotor muß reibungsarme Schmierung hauptsächlich auf verschiedenen gleitenden Oberflächen unter unterschiedlichen Bedingungen liefern, wie Kolbenringen, Zylinderauskleidungen, Lagern für Kurbelwelle und Pleuelstange, Ventilbetriebsmechanismen einschließlich Nockenwellen und Ventilhebern und dergleichen. Für ein Schmieröl für einen Verbrennungsmotor werden reibungsvermindernde Eigenschaften unter unterschiedlichen Gleitbedingungen als unverzichtbar angesehen.In power transmission devices such as internal combustion engines, automatic transmissions, shock absorbers and power control systems, lubricating oil is used to make their operation less frictional. In particular, lubricating oil for an internal combustion engine is required to provide low-friction lubrication mainly to various sliding surfaces under different conditions, such as piston rings, cylinder liners, bearings for crankshaft and connecting rod, valve operating mechanisms including camshafts and valve lifters, and the like. For a lubricating oil for an internal combustion engine, friction-reducing properties under different sliding conditions are considered indispensable.
Zudem gibt es, wenn man mit dem neueren Trend zu Motoren mit höheren Leistungen wie höheren Kilometerzahlen pro Treibstoffeinheit und höherer Leistungsabgabe und schärferen Betriebsbedingungen mithält, eine verstärkte Nachfrage nach besserer Schmierleistung. Wenn andererseits Verbrennungsgas selbst teilweise als Blowby-Gas in einem Verbrennungsmotor zwischen Kolben und Zylinder in ein Kurbelgehäuse leckt, zerstört Stickoxidgas, das in erheblich hoher Konzentration in dem Verbrennungsgas zusammen mit Sauerstoff in dem Blowby-Gas enthalten ist, ein Schmieröl für den Verbrennungsmotor. Aufgrund der Ent wicklung in Richtung Verbrennungsmotoren mit höherer Leistung in den letzten Jahren enthält Verbrennungsgas, das in ein Kurbelgehäuse leckt, Stickoxidgas in einer höheren Konzentration. Es ist daher extrem wichtig für ein Schmieröl für einen Verbrennungsmotor, einen niedrigen Reibungskoeffizienten unter verschiedenen Gleitbedingungen zu liefern und zudem einen solchen niedrigen Reibungskoeffizienten über einen längeren Zeitraum aufrechtzuerhalten.In addition, keeping up with the recent trend of engines with higher performances such as higher mileage per unit of fuel and higher power output and more severe operating conditions, there is an increased demand for better lubricating performance. On the other hand, when combustion gas itself partially leaks into a crankcase as blow-by gas in an internal combustion engine between piston and cylinder, nitrogen oxide gas contained in a considerably high concentration in the combustion gas together with oxygen in the blow-by gas destroys a lubricating oil for the internal combustion engine. Due to the de With the development toward higher power internal combustion engines in recent years, combustion gas leaking into a crankcase contains nitrogen oxide gas in a higher concentration. It is therefore extremely important for a lubricating oil for an internal combustion engine to provide a low coefficient of friction under various sliding conditions and also to maintain such a low coefficient of friction over a longer period of time.
Da an jedem geschmierten reibenden Teil eines Verbrennungsmotors ein wesentlicher Energieverlust stattfindet, muß einem Schmieröl konventionellerweise Reibungsmodifizierungsmittel zugesetzt werden, um den Reibungsverlust zu vermindern und die Kilometerleistung pro Kraftstoffeinheit zu verbessern. Als beispielhafte Reibungsmodifizierungsmittel werden allgemein Organomolybdänverbindungen, Fettsäureester, Alkylamine und dergleichen verwendet. Für eine beispielhafte Schmierölzusammensetzung, die eine Organomolybdänverbindung einsetzt, kann beispielsweise auf die japanische offengelegte Patentanmeldung (Kokai) Nr. SHO 59- 122597 (EP-A-0 113 045) verwiesen werden. Dieser Veröffentlichung zufolge wird eine Schmierölzusammensetzung vorgeschlagen, die (a) Molybdänoxysulfid-Organophosphorthioat und/oder Molybdändithiocarbamat und (b) Zinkdithiophosphat kombiniert verwendet. Die in den Veröffentlichungen offenbarte Schmierölzusammensetzung hat einen niedrigen Reibungskoeffizienten und zeigt reibungsvermindernde Effekte in dem anfänglichen Stadium ihrer Verwendung, weist jedoch den Nachteil auf, daß sie ihre Wirkungen nicht während ihrer Verwendung über einen längeren Zeitraum aufrechterhalten kann, insbesondere in Anwesenheit von Stickoxidgas.Since a substantial energy loss occurs at each lubricated rubbing part of an internal combustion engine, friction modifiers must conventionally be added to a lubricating oil to reduce friction loss and improve mileage per unit of fuel. As exemplary friction modifiers, organomolybdenum compounds, fatty acid esters, alkylamines and the like are generally used. For an exemplary lubricating oil composition employing an organomolybdenum compound, reference may be made, for example, to Japanese Patent Application Laid-Open (Kokai) No. SHO 59-122597 (EP-A-0 113 045). According to this publication, a lubricating oil composition is proposed which uses (a) molybdenum oxysulfide organophosphorothioate and/or molybdenum dithiocarbamate and (b) zinc dithiophosphate in combination. The lubricating oil composition disclosed in the publications has a low friction coefficient and exhibits friction-reducing effects in the initial stage of its use, but has the disadvantage that it cannot maintain its effects during its use over a longer period of time, particularly in the presence of nitrogen oxide gas.
Andererseits offenbart die japanische offengelegte Patentanmeldung (Kokai) Nr. HEI 8-73878 (EP-A-0 699 739) eine Motorölzusammensetzung, die (a) Molybdändithiocarbamat und (b) Zinkdithiophosphat und ferner (c) aschefreies Organopolysulfid kombiniert einsetzt, wobei beansprucht wird, daß sie einen niedrigen Reibungskoeffizienten über einen längeren Zeitraum aufrechterhalten kann. Diese Schmierölzusammensetzung wird jedoch von dem Problem begleitet, daß der Reibungskoeffizient im niedrigen Gleitgeschwindigkeitsbereich unter hin- und hergehender Reibung höher wird. Sie wird daher nicht als eine ausreichende Qualität zur Verwendung unter sich verändernden Bedingungen aufweisend angesehen, wie als Schmieröl für einen Verbrennungsmotor eines Autos, in dem die Gleitbedingungen erheblich variieren.On the other hand, Japanese Patent Application Laid-Open (Kokai) No. HEI 8-73878 (EP-A-0 699 739) discloses an engine oil composition which uses (a) molybdenum dithiocarbamate and (b) zinc dithiophosphate and further (c) ashless organopolysulfide in combination, claiming that it can maintain a low friction coefficient for a long period of time. However, this lubricating oil composition is not approved by the It is accompanied by a problem that the friction coefficient becomes higher in the low sliding speed range under reciprocating friction. It is therefore not considered to be of sufficient quality for use under changing conditions, such as a lubricating oil for an internal combustion engine of an automobile in which the sliding conditions vary considerably.
In Anbetracht der oben beschriebenen Situationen der bislang entwickelten Schmieröle mit reibungsvermindernden Eigenschaften hat die vorliegende Erfindung die Aufgabe, eine Schmierölzusammensetzung zu schaffen, die reibungsvermindernde Eigenschaften aufrechterhalten kann, selbst wenn die Gleitbedingungen in einem Verbrennungsmotor erheblich variieren, und die solche reibungsvermindernden Eigenschaften über einen längeren Zeitraum aufrechterhalten kann, insbesondere sogar in Anwesenheit von Stickoxidgas.In view of the above-described situations of the lubricating oils having friction reducing properties developed so far, the present invention has an object to provide a lubricating oil composition which can maintain friction reducing properties even when the sliding conditions in an internal combustion engine vary considerably and which can maintain such friction reducing properties over a long period of time, particularly even in the presence of nitrogen oxide gas.
Zur Lösung der oben beschriebenen Probleme haben die Erfinder intensiv geforscht. Als Resultat ist gefunden worden, daß eine Kombination aus Organomonosulfidverbindung und Organopolysulfid mit Organomolybdänverbindung es ermöglicht, niedrige Reibungskoeffizienten unter verschiedenen Gleitbedingungen zu liefern und zudem die reibungsvermindernden Eigenschaften im Gebrauch über einen längeren Zeitraum aufrechtzuerhalten. Dieser Fund hat nun zur Fertigstellung der vorliegenden Erfindung geführt.To solve the problems described above, the inventors have conducted intensive research. As a result, it has been found that a combination of organomonosulfide compound and organopolysulfide with organomolybdenum compound makes it possible to provide low friction coefficients under various sliding conditions and also to maintain the friction-reducing properties in use over a longer period of time. This discovery has now led to the completion of the present invention.

However, alkyl groups are not limited to those given as examples, and as one of the two hydrocarbon groups, an alkyl group having an even longer chain may be used, provided that the average carbon number of the two hydrocarbon groups falls within a range of 1 to 20.

Andererseits kann ein Anteil über 2000 ppm keine zusätzlichen Reibungsverminderungseffekte entsprechend der Erhöhung bringen und fördert zudem die Korrosion, wodurch sich ein praktisches Problem entwickelt.The content of the organomonosulfide compound is in the range of 80 to 1800, preferably 100 ppm to 1500 ppm as sulfur content (S).

On the other hand, a content of more than 2000 ppm cannot bring about additional friction reducing effects corresponding to the increase and also promotes corrosion, thereby developing a practical problem.

Hinsichtlich der so erhaltenen Schmierölzusammensetzungen wurden Reibungscharakteristika von Frischölen und gebrauchten Ölen nach NOx-Oxidationstests nach dem folgenden Testverfahren bewertet.Lubricating oil compositions were prepared by mixing additives in proportions shown in Table 1 and Table 2 into the base oil described above. With respect to the lubricating oil compositions thus obtained, friction characteristics of fresh oils and used oils were evaluated after NOx oxidation tests according to the following test method.
Reibungskoeffizienten von jedem der Frischöle und gebrauchten Öle wurden unter den folgenden Testbedingungen mittels eines sich hin und her bewegenden Reibungstesters gemessen, um ihre Reibungscharakteristika unter verschiedenen Reibungsbedingungen zu bestimmen. Als Reibungskoeffizient wurde jeweils ein Wert verwendet, der nach einer Testzeit von 20 Minuten erhalten wurde.Friction coefficients of each of the fresh oils and used oils were measured under the following test conditions using a reciprocating friction tester to determine their friction characteristics under various friction conditions. A value obtained after a test time of 20 minutes was used as the friction coefficient in each case.
Der Reibungstest wurde durchgeführt, indem ein Ölfilm eines Probeöls auf einer Scheibe gebildet wurde, ein Zylinder auf den Ölfilm getan wurde und dann der Zylinder horizontal über eine festgelegte Breite unter einer festgelegten Last oszilliert wurde. DIN100CR&sub6; (HRc62, entsprechend JIS SUJ2) wurde als Material für sowohl den Zylinder als auch die Scheibe verwendet. Testbedingungen The friction test was carried out by forming an oil film of a sample oil on a disk, placing a cylinder on the oil film and then the cylinder was oscillated horizontally over a specified width under a specified load. DIN100CR₆ (HRc62, corresponding to JIS SUJ2) was used as the material for both the cylinder and the disk. Test conditions

Beispiele 1 bis 10 betreffen erfindungsgemäße Schmierölzusammensetzungen mit hohen reibungsvermindernden Eigenschaften wie in Tabelle 1 gezeigt.Examples 1 to 10 relate to lubricating oil compositions according to the invention with high friction-reducing properties as shown in Table 1.
Beispiele 1 bis 3 zeigen Schmierölzusammensetzungen mit hohen reibungsvermindernden Eigenschaften, wobei jede erhalten wurde, indem 150 Neutralöl als Basisöl gewählt wurde, C&sub8;MoDTC [Molybdänoxysulfid-N,N-di(2-ethylhexyl)dithiocarbamat]als Organomolybdänverbindung eingesetzt wurde und die Organomonosulfid verbindung und die Organopolysulfidverbindung in Kombination verwendet wurden.Examples 1 to 3 show lubricating oil compositions having high friction reducing properties, each obtained by choosing 150 neutral oil as the base oil, using C�8 MoDTC [molybdenum oxysulfide-N,N-di(2-ethylhexyl)dithiocarbamate] as the organomolybdenum compound, and the organomonosulfide compound and the organopolysulfide compound were used in combination.
Beispiele 4 bis 6 präsentieren Schmierölzusammensetzungen mit hohen reibungsvermindernden Eigenschaften, wobei jede erhalten wurde, indem als Organomolybdänverbindung CBMoDTP [Molybdänoxysulfid-N,N-di(2-ethylhexyl)phosphorthioat] anstelle von C&sub8;MoDTC in den Beispielen 1 bis 3 eingesetzt wurde und die Organomonosulfidverbindung und die Organopolysulfidverbindung in Kombination verwendet wurden.Examples 4 to 6 present lubricating oil compositions with high friction reducing properties, each of which was obtained by using as the organomolybdenum compound CBMoDTP [molybdenum oxysulfide-N,N-di(2-ethylhexyl)phosphorothioate] in place of C8MoDTC in Examples 1 to 3 and using the organomonosulfide compound and the organopolysulfide compound in combination.
Ferner zeigen Beispiele 7 bis 10 Schmierölzusammensetzungen mit hohen reibungsvermindernden Eigenschaften, wobei jede von ihnen erhalten wurde, indem als Organomolybdänverbindung sowohl C&sub8;MoDTC als auch C&sub8;MoDTP in Kombination eingesetzt wurden und die Organomonosulfidverbindung und die Organopolysulfidverbindung in Kombination verwendet wurden.Further, Examples 7 to 10 show lubricating oil compositions having high friction reducing properties, each of which was obtained by using, as the organomolybdenum compound, both C₈MoDTC and C₈MoDTP in combination and using the organomonosulfide compound and the organopolysulfide compound in combination.
Vergleichsbeispiele 1 bis 6 betreffen Schmierölzusammensetzungen, von denen jede die Organomolybdänverbindung allein oder die Organomolybdänverbindung und die Organomonosulfidverbindung und/oder Organopolysulfid verwendeten, wobei der Anteil/die Anteile jedoch außerhalb des entsprechenden Bereichs bzw. der entsprechenden Bereiche der Erfindung wie in Tabelle 2 gezeigt lag bzw. lagen. Vergleichsbeispiel 1 betrifft eine Schmierölzusammensetzung, die nur C&sub8;MoDTC als Organomolybdänverbindung einsetzte und weder Organomonosulfidverbindung noch Organopolysulfidverbindung verwendete. Verglichen mit der Schmierölzusammensetzung aus Beispiel 1 enthielt die Schmierölzusammensetzung von Vergleichsbeispiel 1 C&sub8;MoDTC in dem gleichen Anteil als Additiv, enthielt aber nicht die oben beschriebene Schwefelverbindung als Additiv. Es wird daher gezeigt, daß das Frischöl und das gebrauchte Öl beide hohe Reibungskoeffizienten hatten und der unter den Bedingungen 1 erhaltene Reibungskoeffizient besonders hoch war. Vergleichsbeispiel 2 betrifft eine Schmierölzusammensetzung, die C&sub8;MS als Organomonosulfidverbindung und C&sub8;DS als Organopolysulfidverbindung verwendete, der Anteil an C&sub8;MS betrug jedoch 50 ppm und lag somit außerhalb des Proportionsbereichs der erfindungsgemäß verwendeten Organomonosulfidverbindung. Obwohl die Organomonosulfidverbindung und die Organopolysulfidverbindung in Kombination verwendet wurden, zeigt Vergleichsbeispiel 2, daß der Reibungskoeffizient unter den Bedingungen 1 hoch wird, selbst wenn der Anteil an Organomonosulfidverbindung unter dem spezifizierten Niveau liegt. Andererseits wird aus Vergleichsbeispiel 3 beobachtet, daß der Reibungskoeffizient unter den Bedingungen 2 hoch wird, wenn der Anteil an Organopolysulfidverbindung unter dem spezifizierten Niveau liegt. Vergleichsbeispiel 4 betrifft eine Schmierölzusammensetzung, die C&sub8;MoDTP statt C&sub8;MoDTC enthält, der Anteil an DPDS betrug jedoch 40 ppm und lag damit unter dem spezifizierten Niveau. Der Reibungskoeffizient unter den Bedingungen 2 ist extrem hoch. Vergleichsbeispiele 5 und 6 betreffen Schmierölzusammensetzungen, in denen der Anteil der Organomolybdänverbindung unter dem spezifizierten Niveau lag. Sowohl die Frischöle als auch die gebrauchten Öle zeigten extrem hohe Reibungskoeffizienten.Comparative Examples 1 to 6 relate to lubricating oil compositions each of which used the organomolybdenum compound alone or the organomolybdenum compound and the organomonosulfide compound and/or organopolysulfide, but the proportion(s) were outside the corresponding range(s) of the invention as shown in Table 2. Comparative Example 1 relates to a lubricating oil composition which used only C₈MoDTC as the organomolybdenum compound and used neither organomonosulfide compound nor organopolysulfide compound. Compared with the lubricating oil composition of Example 1, the lubricating oil composition of Comparative Example 1 contained C₈MoDTC in the same proportion as an additive, but did not contain the above-described sulfur compound as an additive. It is therefore shown that the fresh oil and the used oil both had high friction coefficients, and the friction coefficient obtained under Conditions 1 was particularly high. Comparative Example 2 relates to a lubricating oil composition using C�8MS as organomonosulfide compound and C�8DS as organopolysulfide compound, the proportion of However, C8MS was 50 ppm, which was outside the proportion range of the organomonosulfide compound used in the present invention. Although the organomonosulfide compound and the organopolysulfide compound were used in combination, Comparative Example 2 shows that the friction coefficient under the condition 1 becomes high even when the proportion of the organomonosulfide compound is below the specified level. On the other hand, it is observed from Comparative Example 3 that the friction coefficient under the condition 2 becomes high when the proportion of the organopolysulfide compound is below the specified level. Comparative Example 4 relates to a lubricating oil composition containing C8MoDTP instead of C8MoDTC, but the proportion of DPDS was 40 ppm, which was below the specified level. The friction coefficient under the condition 2 is extremely high. Comparative Examples 5 and 6 relate to lubricating oil compositions in which the proportion of the organomolybdenum compound was below the specified level. Both the fresh oils and the used oils showed extremely high friction coefficients.
Vergleichsbeispiel 7 betrifft Schmierölzusammensetzungen, in denen jeweils C&sub8;MoDTC als Organomolybdänverbindung in dem gleichen Anteil wie in Beispiel 1 zugegeben wurde, aber nur die Organomonosulfidverbindung (C&sub8;MS) verwendet wurde und keine Organopolysulfidverbindung in Kombination verwendet wurde.Comparative Example 7 relates to lubricating oil compositions, in each of which C8MoDTC was added as an organomolybdenum compound in the same proportion as in Example 1, but only the organomonosulfide compound (C8MS) was used and no organopolysulfide compound was used in combination.
Vergleichsbeispiel 8 betrifft eine Schmierölzusammensetzung, in der nur die Organopolysulfidverbindung (C&sub8;DS) verwendet wurde und kein Organomonosulfid in Kombination verwendet wurde. Das Frischöl und das gebrauchte Öl hatten beide hohe Reibungskoeffizienten. Es sei daher darauf hingewiesen, daß die kombinierte Verwendung von Organomonosulfidverbindung und Organopolysulfidverbindung unabdingbar ist, um reibungsvermindernde Effekte zu erhalten.Comparative Example 8 relates to a lubricating oil composition in which only the organopolysulfide compound (C8DS) was used and no organomonosulfide was used in combination. The fresh oil and the used oil both had high friction coefficients. It should therefore be noted that the combined use of organomonosulfide compound and organopolysulfide compound is indispensable in order to obtain friction-reducing effects.
Gemäß Vergleichsbeispiel 9 wird andererseits eine Schmierölzusammensetzung gezeigt, die sowohl die Organomonosulfidverbindung (C&sub8;MS) als auch die Organopolysulfidverbindung (C&sub8;DS) enthielt, aber keine Organomolybdänverbindung verwendete. Es ist offensichtlich, daß keine ausreichenden reibungsvermindernden Effekte erhalten werden können, wenn keine Organomolybdänverbindung verwendet wird.On the other hand, according to Comparative Example 9, there is shown a lubricating oil composition containing both the organomonosulfide compound (C₈MS) and the organopolysulfide compound (C₈DS) but not using an organomolybdenum compound. It is obvious that no sufficient friction reducing Effects can be obtained if no organomolybdenum compound is used.
Es ist somit ersichtlich, daß diese Erfindung eine Schmierölzusammensetzung liefert, die erhalten wird, indem als wesentliche Komponenten Organomolybdänverbindung, Organomonosulfidverbindung und Organopolysulfidverbindung jeweils in spezifizierten Anteilen zugesetzt werden. Die Schmierölzusammensetzung hat hervorragende reibungsvermindernde Eigenschaften unter verschiedenen Gleitbedingungen von unterschiedlichen Gleitgeschwindigkeiten und sogar in Anwesenheit von Stickoxidgas und kann Sauerstoffbeständigkeit zeigen, um reibungsvermindernde Eigenschaften beizubehalten. Die erfindungsgemäße Schmierölzusammensetzung ist daher geeignet als Schmieröl für Verbrennungsmotoren, Automatikgetriebe, Stoßdämpfer und Kraftsteuerungssysteme, insbesondere für Verbrennungsmotoren. Tabelle 1 It is thus seen that this invention provides a lubricating oil composition obtained by adding, as essential components, organomolybdenum compound, organomonosulfide compound and organopolysulfide compound each in specified proportions. The lubricating oil composition has excellent friction reducing properties under various sliding conditions of different sliding speeds and even in the presence of nitrogen oxide gas, and can exhibit oxygen resistance to maintain friction reducing properties. The lubricating oil composition of the present invention is therefore suitable as lubricating oil for internal combustion engines, automatic transmissions, shock absorbers and power control systems, particularly for internal combustion engines.
