Definitions
- the present invention relates to a lubricating composition and, more particularly, to a high temperature grease composition used for the lubrication of various machines and apparatuses such as automobiles, electric appliances, construction machines and machine tools as well as bearings and to a lubricating oil composition used for a long period of time under high temperatures in oil hydraulic, compression and vacuum pumps, bearings, gears, etc.
- a lubricating composition is widely used in various machines such as automobiles, electric appliances, construction machines and machine tools. Such machines have been demanded year by year for meeting requirements of compact size, high output, light weight and simple maintenance. As a consequence, lubricating conditions of lubricating compositions become severe more and more.
- To make a machine compact in size and high in output is to reduce the dimension thereof when the output thereof is the same. When the dimension is reduced, the heat energy discharged from surfaces of the machine is reduced to cause an increase of the temperature of a lubrication section thereof.
- a material that has low heat conductivity such as a non-metal. This results in a further increase of the temperature.
- Simple maintenance has the same meaning as extension of service life. To extend the oxidation life, the lubrication characteristics must be kept for a long time. In this circumstance, there is a demand for a lubricating composition having a long oxidation life so that the lubricating characteristics thereof can be maintained for a long period of time, particularly a high temperature grease composition having a high dropping point and a high temperature lubricating oil composition.
- Patent Document 1 discloses a grease containing a metal deactivator for plastics and a lithium salt of a hydroxyfatty acid, a dilithium salt of an aliphatic dicarboxylic acid or a lithium salt of an aliphatic monocarboxylic acid.
- Patent Document 2 discloses a grease composition including a base oil of a synthetic lube oil, a thickening agent of a urea compound, (a) an aromatic amine compound and (b) a hindered ester compound and further containing (c) at least one compound selected from phthalimide compounds and phosphoric ester compounds having an aromatic ring.
- Patent Document 3 discloses a grease composition containing a base oil, a thickening agent, an antioxidant and an aromatic dibasic acid or a metal salt of an aromatic dibasic acid (excluding lithium terephthalate).
- Patent Document 4 discloses a grease composition obtained by compounding a thickening agent composed of a C 12 to C 24 fatty acid having at least one hydroxyl group and a lithium salt of a C 2 to C 12 aliphatic dicarboxylic acid into a base oil which contains, as essential ingredients, a mineral oil having a kinematic viscosity at 40°C of 300 to 500 mm 2 /s and a synthetic hydrocarbon oil having a kinematic viscosity at 40°C of 20 to 300 mm 2 /s and which has a kinematic viscosity at 40°C of 60 to 200 mm 2 /s.
- Patent Document 5 discloses a lubricating composition for rolling bearings which contains (a) a urethane prepolymer having an isocyanate group content of 6 to 10 % by weight, (b) a grease selected from a metal soap type grease and a non-metal soap type grease, and (c) an amine curing agent, and which has a hardness after curing of 60 to 85 in International Rubber Hardness Degree (IRHD).
- IRHD International Rubber Hardness Degree

It is preferred that the aromatic carboxylic acid and/or C 2 to C 12 aliphatic dicarboxylic acid be present in an amount of 20 to 90 % by mass based on a total mass of the fatty acid and/or C 12 to C 24 hydroxyfatty acid having at least one hydroxyl group and the aromatic carboxylic acid and/or C 2 to C 12 aliphatic dicarboxylic acid. This is because a thickening agent having good thermal stability may be obtained and a grease composition having a long service life at high temperatures may be advantageously obtainable when the amount is within the range of 20 to 90 % by mass.
- a urea compound or bentonite treated with an organic compound may be used.
- the urea compound used as the thickening agent there may be mentioned a diurea compound, a triurea compound, a tetraurea compound and a urea-urethane compound. Because the urea compound has excellent heat resistance and water resistance and is particularly excellent in stability at high temperatures, it is suitably used in a high temperature environment.
- the diurea compound there may be mentioned, for example, a compound represented by the formula R 8 NHCONHR 9 NHCONHR 8 (wherein R 8 represents a straight chained or branched, saturated or unsaturated C 6 to C 24 alkyl group and R 9 represents a divalent C 6 to C 15 aromatic hydrocarbon group).
- the typical diurea compound may be obtained by reaction of a diisocyanate with a monoamine.
- the diisocyanate may be, for example, diphenylmethane diiocyanate, phenylene diisocyanate, diphenyl diisocyanate, phenyl diisocyanate or tolylene diisocyanate.
- the monoamine may be, for example, octylamine, dodecylamine, hexadecylamine, cyclohexylamine, aniline, toluidine, octadecylamine or oleylamine.

- the oxidation life is a time period taken for the ratio (I 720 )/(I 1710 ) of the transmittance at 720 cm -1 to the transmittance at 1710cm -1 to be 1.2 or more.
- Oil separation was measured in accordance with JIS K2220, but using a measuring temperature of 180°C.
- a tester (ASTM D3336) was continuously operated at 10,000 rpm and at 180°C.
- the bearing life is a time period (in hours) for the tester to become no longer operable due to "burning".
- a sample (1 g) was allowed to stand in the vessel at 170°C for 48 hours.
- the amount of the oil remaining in the vessel was then measured, from which an oil remaining percent was calculated.
- air was continuously fed to the vessel at a flow rate of 10 L/hr. The greater the oil remaining percent, the less likely the thermal decomposition is to occur, i.e. the better is the stability at high temperatures.
- the lubricating oil was allowed to stand and cool at room temperature.
- the vessel was then slanted to determine the fluidity with naked eyes.
- the grease compositions of Example. 1 and Comparative Examples 3, 6 and 8 were each measured for the above-described bearing life.
