Definitions
- the present invention relates to lubricating oil compositions which suppress the formation of sludge and which have excellent storage stability, low friction properties, small pressure transmission loss, low supply pressure loss in pipe-work, and low flammability.
- Hydraulic systems are distinguished in that the "oil" which is the motive power transmitting medium has low compressibility and so it is possible to use higher pressures and to increase the output with respect to the weight of a machine, and for many reasons such as the fact that the division, concentration and speed control of the motive power can be achieved easily, such oils are widely used in industrial applications.
- the Hydraulic Fluid Handbook page 31, published in 1985 by the Lubrication News Agency Co. Ltd., describes that the feed pressure loss in hydraulic pipe-work based on the Bernoulli ' s theorem is proportional to the density of the oil both in a vacuum pipe and in a vented pipe, elbow, branch pipe or linked pipe.
- the supply pressure loss can be reduced by reducing the density if the kinematic viscosity and the pipe-work are the same, and it is also shown that at the same time an improvement in flow-rate efficiency can be devised by reducing the density.
- the supply pressure loss in hydraulic pipe-work is converted to heat and sound etc., it is suggested that the generation of heat and noise are also suppressed by reducing the density. Since reduced friction also contributes to improving energy conservation, low friction properties to an extent where stick-slip does not arise in steel-steel situations is required.
- the present invention now surprisingly enables energy conservation to be achieved by improving the performance of monograde hydraulic oils as the hydraulic media for increasing the efficiency of hydraulic energy transmission.
- the present invention provides a lubricating oil composition
- a lubricating oil composition comprising lubricating oil base oil, wherein said composition has a kinematic viscosity at 40°C of from 18 to 60 mm 2 /s, a viscosity index of from 130 to 150 and a density at 15°C of from
- a lubricating oil composition in which not only has the density been reduced by about 10% when compared with the commercial industrial lubricating oil products of the same viscosity and which surprisingly has an energy conserving effect, but which also has a flash point of at least 250°C as measured by JIS K 2265 by using a narrow-cut base oil.
- the narrow-cut base oils having a high flash point for industrial lubricating oil products are very different in terms of their molecular weight distribution from the usual base oils used by those in the industry and the proportion of high molecular weight hydrocarbon components is very small. Consequently, the solubilities of lubricating oil additives which control various aspects of performance are very low and there is a disadvantage in that turbidity and precipitates are produced, and these materials cannot be used as industrial lubricating oils.
- the high molecular weight ashless dispersants used in the automobile lubricating oils cannot be used in hydraulic applications even at treat rates of less than 1 %wt., e.g. 0.1 %wt., due to emulsification in the presence of water, which is an undesirable property therefor.
- the solubility, the low friction properties and anti-rust properties when using a specified narrow-cut base oil in industrial lubricating oils with a view to increasing energy conservation and having a high flash point may be surprisingly improved by the use of a specific a ine compound.
- Japanese Unexamined Patent Application Laid Open 2002-338 983 there is disclosed a lubricating oil composition where an alkylamine has been added to a lubricating oil base oil, but the amount of anti-rust agent is greatly reduced by combining the alkylamines with the anti-rust agent and, as a result, the extreme pressure performance by the anti-rust agent is suppressed to the lowest level.
- the primary amine having a tertiary alkyl group in the present invention as the primary amine.
- the lubricating oil base oil used is preferably a base oil of which the minimum value of the kinematic viscosity at 40°C is preferably 8 mm /s and more desirably 10 mm 2 /s, and the maximum value of the kinematic viscosity at 40°C is preferably 60 mm 2 /s and more desirably 40 mm /s. It is also disclosed that from the viewpoint of minimising as far as possible the change in the damping force the viscosity index is preferably at least 80 and more desirably at least 95, but there is no disclosure of the lubricating oil base oil of the present invention.
- the lubricating oil base oil used is preferably a base oil of which the minimum value of the kinematic viscosity at 40°C is preferably 8 mm 2 /s and more desirably 10 mm 2 /s, and the maximum value of the kinematic viscosity at 40°C is preferably 60 mm 2 /s and more desirably 40 mm 2 /s. It is further disclosed that from the viewpoint of minimising as far as possible the change in the damping force the viscosity index is preferably at least 80 and more desirably at least 95, but there is no disclosure of the lubricating oil base oil of the present invention.
- the use of an oil of which the minimum value of the kinematic viscosity at 40°C is preferably 8 mm 2 /s and more desirably 10 mm /s, and the maximum value of the kinematic viscosity at 40°C is preferably 60 mm /s and more desirably 40 mm /s is desirable.
- the viscosity index is preferably at least 80 and more desirably at least 95, but there is no disclosure of the fact that the viscosity index is at least 130 and the density is not more than 0.84 g.cm -3 a s in the case of the lubricating oil base oil of the present invention.
- the present invention surprisingly provides a lubricating oil composition with which the formation of sludge is suppressed even when the usual lubricating oil additives are compounded, which has excellent storage stability, which has low friction properties, with which the pressure transmission loss is small, with which the supply pressure loss in pipe-work is small, and which has low flammability.
- the present invention provides a lubricating oil composition
- a lubricating oil composition comprising lubricating oil base oil, wherein said composition has a kinematic viscosity at 40°C of from 18 to 60 mm 2 /s, a viscosity index of from 130 to 150, a density at 15°C of from 0.80 to 0.84 g.cm -3 and a flash point of at least 220°C as measured by JIS K 2265.
- the lubricating oil composition may further comprise a primary amine which has a Cg to C20 tertiary alkyl group which can be represented by general formula (1) below
- the lubricating oil composition of the present invention may conveniently have from 0.001 to 5.0 parts by weight of the primary amine represented by general formula (1) is compounded per 100 parts by weight of the lubricating oil composition.
- the present invention further provides a hydraulic oil, a machine tool oil, a gear oil, a compressor oil, a turbine oil, a bearing oil and a heat transfer fluid wherein lubricating oil additives are compounded into the lubricating oil composition of the present invention.
- the lubricating oil base oil component from which the lubricating oil composition of the present invention is constituted is a base oil which comprises petroleum- based and/or synthetic hydrocarbons.
- the lubricating oil compositions of the present invention have the same kinematic viscosity, viscosity index, density and flash point of the lubricating oil base oil because of the major effect provided by the properties of the base oil which is compounded therein.
- the kinematic viscosity at 40°C measured on the basis of the test method laid down in JIS K 2283 is generally from 18 to 60 mm /s, preferably from 25 to 53 mm /s, and more preferably from 28 to 51 mm 2 /s. If the kinematic viscosity at 40°C is higher than 60 mm /s then even though the density is low, the supply pressure loss in hydraulic equipment pipe-work is considerable and the energy conserving performance is inevitably poor. Furthermore, if it is less than 18 mm 2 /s then not only is it impossible to maintain a flash point of at least 250°C, but then there are also types of equipment in which problems arise with wear resistance and this is undesirable.
- the kinematic viscosity at 40°C referred to herein corresponds to ISO VG32 and ISO VG46 in the viscosity distribution of industrial lubricating oils as defined in ISO 3448 and ASTM D 2422.
- a high viscosity index signifies that the temperature dependence of the lubricating oil viscosity is small and, for example, the temperature of the hydraulic oil when hydraulic equipment is first started is low and, while a hydraulic oil which has a low viscosity index will have a high viscosity, a hydraulic oil which has a high viscosity index will have a low viscosity at low temperature and it is possible to reduce the power consumption on start-up.
- the viscosity index as defined in JIS K 2283 is generally from 130 to 150, preferably from 132 to 150 and most desirably from 135 to 150.
- the viscosity index at 40°C is 46 mm /s and the viscosity index is 110
- the kinematic viscosity at 10°C is 283.06 mm 2 /s
- the viscosity index is 130
- the kinematic viscosity at 10°C is 250.1 mm /s and if the viscosity index is 135 then it is 242.98 mm 2 /s and the room temperature viscosity changes markedly according to the viscosity index, and since the electrical power consumption also increases in accordance with the kinematic viscosity, a high viscosity index is also desirable for reducing the power consumption on start-up.
- the density at 15°C of the lubricating oil base oil measured by the method for measuring the density of lubricating oil defined in JIS K 2249 is generally from 0.80 to 0.84 g.cm -3 , preferably from 0.81 to 0.84 g.cm -3 , more desirably from 0.815 to 0.835 g.cm -3 and most desirably from 0.820 to 0.830 g.cm -3 .
- hydraulic equipment generally operates at an oil temperature of from 40 to 60°C, but in the case of a density at 15°C of 0.84 g.cm -3 , the density, when calculated using the density calculation method indicated in JIS K 2249, at 40°C is 0.8233 g.cm -3 , at 50°C is
- 0.8167 g.cm -3 and at 60°C is 0.8100 g.cm -3 , and so the density at 40°C is preferably not more than 0.8167 g.cm -3 , the density at 50°C is preferably not more than
- 0.8167 g.cm -3 and the density at 60°C is preferably not more than 0.8100 g.cm -3 .
- a lubricating oil composition which has low friction properties contributes to energy conservation, it is preferred that there are low friction properties such that stick-slip does not occur in steel- steel situations.
- the flash point of the lubricating oil base oil as measured using the Cleveland formula defined in JIS K 2265 is generally at least
- JIS K 2265 is 8°C, a value of at least 258°C is most desirable for ensuring an actual flash point of at least
- any of the petroleum-based lubricating oil base oils x ⁇ ich have the properties outlined above can be conveniently used in the present invention. However, in general these properties cannot be realised with solvent refined base oils and ordinary hydrogenation refined base oils.
- the narrow-cut base oils wherein the molecular weight distribution of the hydrocarbons in the base oil is very narrow can be cited as base oils which do satisfy these conditions.

- these three types of narrow-cut base oil are used individually or in the form of mixtures so as to provide the prescribed viscosity. Such narrow-cut oils also exhibit especially good volatilisation resistance.
- composition of these narrow-cut base oils is such that with the method of measurement laid down in ASTM D 3238, the aromatic content (%CA) is not more than 0.1 wt% and the paraffin content (%Cp) is at least 85 wt%, the iso-paraf in content is at least 80 wt%, the elemental sulphur content is not more than 50 ppm, the elemental nitrogen content is not more than 5 ppm, the total polar material is not more than 1% and the properties are: refractive index at least 1.45, aniline point at least 120°C and they are colourless and transparent, being classified as L0.5 using the colour test method laid down in ASTM D 1500.

- the sample oil was introduced into a clear gloss bottle and left to stand in the dark in the open air in winter with a view to evaluating solubility, and those where there was no turbidity or precipitate formation were adjudged to have passed the test.
- the open air temperature varied gradually between 5 and -5°C.
- the lubricating oil compositions of the present invention have excellent thermal oxidation stability, lubricating properties and filtration characteristics from the viewpoint of both the safety aspects and the actual performance of the compositions. It will be appreciated that the kinematic viscosity at 40°C, viscosity index and density of the fluids in the above tables are resultant from the base oil used therein.
- Example 11 and Comparative Examples 16 to 18 are resultant from the base oil used therein.
- Example 11 The formulations tested in Example 11 and Comparative Examples 16-18 were as described in Table 6:
- test conditions were designed to mimic industrial applications where possible.
- a HBM torque transducer was used to take measurements of torque, along with calibrated speed and input power readings and the mechanical efficiency was calculated.
- the first test assessed the effects (predicted as no effect) that the relationship between altering swash plate angle or drive speed have on pump efficiency.
- the swash plate was set at different angles and then given running conditions achieved, set flow rate, speed, temperature and pressure so that the displacement of the pump was the only variable. Efficiency calculations were then performed on the data gathered and any effect was found to be below the scope of the measuring equipment, hence the relationship is assumed to be negligible. All other tests were run by differing the drive speed, with a constant swash plate angle to maintain a constant flow.
- Denison hydraulic piston pump rig used to assess hydraulic fluids and pump efficiency, including electrical fault-finding and calibration of the torque transducer.
- a contact box with an over-current switch controls the rig, and a dial linked to an electronic control box allows the drive shaft speed to be adjusted.
- Fluid temperature is varied between room temperature and 80°C.
- Pressure is varied between 0 Bar and 130 Bar under normal test conditions, using a manual screw-in valve.
- Periodically maintenance and cleaning may be required, such as fluid changes and adjustments to the swash plate.
- Example 11 has not only a higher VI than the conventional anti-wear hydraulic oil of Comparative Example 16, but also has a significantly lower density.
- Example 11 surprisingly has the highest relative efficiency as the pump requires less energy per unit of fluid pumped. It would be expected in real systems where a much higher proportion of pipework exists that the benefit would be of the order of 5% or more, which could be determined by monitoring electricity consumption.
- the present invention makes it possible to make use of narrow-cut base oils in industrial lubricating oils to increase energy conservation and raise the flash point where necessary and to provide lubricating oil compositions which, when compared with commercial industrial lubricating oils of the same viscosity, have a density reduced by some 10% and which surprisingly have an energy conserving effect.
- lubricating oil compositions of the present invention may be used in a wide range of industrial lubricating oils, such as hydraulic oils, machine tool oils, gear oils, compressor oils, turbine oils, bearing oils, heat transfer fluids and greases.
