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. That is to say, 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. Moreover, since 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 and a primary amine which has a C 8 to C 20 tertiary alkyl group which can be represented by general formula (1) below wherein x is an integer of value from 1 to 17, y is an integer of value from 1 to 17, z is an integer of value from 1 to 17, and x + y + z is an integer of value from 7 to 19, 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 0.80 to 0.84 g.cm -3 .
  • 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 amine 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.

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.

  • 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.

  • These anti-rust agents can be conveniently used individually or in the form of a combination of a number of types in amounts within the range of from 0.01 to 2 parts by weight per 100 parts by weight, of lubricating oil composition
  • anti-emulsification agents used generally as lubricating oil additives can be conveniently used as anti-emulsification agents in the lubricating oil compositions of the present invention. They can be conveniently used in amounts within the range of from 0.0005 to 0.5 part by weight, per 100 parts by weight of lubricating oil composition.
  • the lubricating oil compositions of the present invention can be used as industrial lubricating oils and, in particular, as hydraulic oils. Moreover, they are also useful as heat transfer fluids, machine tool oils, gear oils, compressor oils, turbine oils, bearing oils and greases in view of their surprising ability to eliminate the pressure loss in hydraulic pipe-work.
  • the sample oil was coated between steel test pieces moved at a slip rate of 12.7 mm/minute with a loading of 22.4 kgf using a stick-slip tester produced by the Cincinnati Milacron Co. (formerly ASTM D 2877) and whether or not sticking occurred was assessed in order to evaluate the low-friction - energy conserving properties of the sample oil.
  • Lubricating oils where stick-slip occurred had a high coefficient of friction and were unsatisfactory in terms of energy conservation and therefore assessed a failure.
  • 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. Moreover, 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.
  • Example 11 Comp. Ex. 16 Comp. Ex. 17 Comp. Ex. 18 Formulation Type Formulation according to the present invention containing 98.97 %wt. of Base Oil 4, 0.03 %wt. of Amine 2.
  • the balance was made up of standard additive components.
  • Anti-wear hydraulic oil according to WO-A-00/63325 .
  • Synthetic biodegradable lubricant Synthetic biodegradable lubricant.
  • Viscosity Modifier improved multigrade hydraulic conventional anti-wear hydraulic fluid.
  • Mineral-oil based (HVI). A commercially available ISO VG 46 environmentally acceptable hydraulic fluid consisting of synthetic esters (HEES) and ashless additives. ISO VG 46. Mineral-oil based (HVI). Ester-based.
  • 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.
  • 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.
