Definitions
- the present invention relates to a lubricating oil composition suitable for use for a main shaft of a machine tool.
- the main shaft of a machine tool is rotated at a high speed in order to raise the working speed of the machine tool.
- the functions of a lubricating oil used for the main shaft are cooling and lubrication of the main shaft, and the lubricating oil needs to have a low viscosity in order to attain high cooling efficiency. Wear resistance is also an important property required of the lubricating oil in order to cope with the impact load of the main shaft. In addition, in cold periods during winter, low temperature fluidity is also required in order to obtain good startability of the machine tool.
- lubricating oils used for machine tools are used not only for lubrication of shaft bearing parts, as mentioned above, but also for lubrication of gear parts, and the like, and in such cases, load-bearing properties are further required as an important property.
- the applicant of the present application has previously attained good results in developing a lubricating oil composition with excellent lubricating properties, which is capable of sufficiently exhibiting performance for a longtime even when used under conditions becoming increasingly severe with speeding up, pressure increase, and downsizing of industrial machines and of securing the lifetime of machines, by blending ⁇ -dithiophosphorylated propionic acid with a mineral oil or a synthetic oil, see for example Japanese Patent Application Publication No. 2002-265971.
- the inventors of the present invention have made various examinations and studies in order to obtain a lubricating oil composition which has even better lubricating properties and wear resistance as well as having a high flash point.
- a lubricating oil composition suitable for use for a main shaft of a machine tool is obtained by using, as a base oil for the lubricating oil composition, abase oil which comprises an oil containing 20 mass % to 49 mass % of n-paraffin components and 51 mass % to 80 mass % of i-paraffin components at a quantity of 90 mass % or more of the total quantity of the base oil and which has a kinematic viscosity at 40° C. of 1 to 5 mm 2 /s, and blending a small quantity of ⁇ -dithiophosphorylated propionic acid and/or an acidic phosphoric acid ester with the base oil.
- the lubricating oil composition of the present invention exhibits good lubricating properties with good low temperature fluidity at shaft bearings of machine tools, and the like, and also exhibits excellent wear resistance and a high flash point (COC) of 100° C. or higher, and can therefore be effectively used as a lubricating oil composition for a main shaft of a machine tool.
- COC high flash point
- the base oil of the present invention can be a paraffin-based base oil obtained by, for example, subjecting a kerosene/light oil fraction, which is obtained by atmospheric distillation of crude oil, to an appropriate combination of refining processes, such as hydrocracking.
- n-paraffin components and i-paraffin components are contained at fixed proportions, and among paraffin components, it is preferable for the content of n-paraffin components to be 20 mass % to 49 mass % and the content of i-paraffin components to be 51 mass % to 80 mass %, and more preferable for the content of n-paraffin components to be 20 mass % to 29 mass % and the content of i-paraffin components to be 71 mass % to 80 mass %.
- Base oil components constituted from these n-paraffin components and i-paraffin components account for 90 mass % or more, and preferably 95 mass % or more, of the total quantity of the base oil in the composition. Moreover, the remainder of the base oil may contain naphthene-based components and aromatic components, but if the total content of naphthene-based components and aromatic components exceeds 10 mass %, the flash point and oxidation stability deteriorate.
- the kinematic viscosity at 40° C. of this type of base oil is 0.5 to 10 mm 2 /s, and preferably 1 to 5 mm 2 /s.
- the total sulfur content in the base oil should be 10 ppm or less, and preferably 1 ppm or less, and the total nitrogen content in the base oil should be less than 10 ppm, and preferably less than 1 ppm.
- the number of hydrocarbon carbon atoms in the base oil having a kinematic viscosity at 40° C. of 1 to 5 mm 2 /s is distributed within the range 10 to 24.
- the number of carbon atoms in a base oil having a kinematic viscosity at 40° C. of 1.98 to 2.42 mm 2 /s is distributed within the range 12 to 16.
- GC-MS Gas chromatography mass spectrometry methods
- GC-MS is a method in which hydrocarbons, which have been separated according to retention time by gas chromatography, are subjected to mass spectrometry, in which the molecular weights and content proportions of the separated hydrocarbons are measured.
- the molecular weight of a paraffin component is 2n+2, and naphthene-based components and aromatic components having ring structures within the molecule do not have molecular weights of 2n+2.
- gas chromatography/flame ionization detection is one method of measuring the content values of straight chain n-paraffins and branched chain i-paraffins among paraffin components.
- n-paraffins and i-paraffins are separated according to number of carbon atoms by the difference in retention time between paraffins, and the content proportions thereof can be quantitatively determined according to detection area. Therefore, by measuring the proportions of n-paraffins in a C 10-24 fraction by means of GC-FID, it is possible to quantitatively determine the content of n-paraffins.
- n-paraffins include n-decane, n-undecane, n-dodecane, n-tridecane, n-tetradecane, n-pentadecane, n-hexadecane, n-heptadecane, n-octadecane, n-nonadecane, n-eicosane, n-heneicosane, n-docosane, n-tricosane and n-tetracosane.
- a GTL (gas-to-liquid) base oil synthesised by a Fischer Tropsch polymerization method which is a technique for obtaining liquid fuels from natural gas, can be advantageously used as the base oil component of the present invention due to having an extremely low sulfur content and aromatic content, a high constituent proportion of paraffin components, exhibiting excellent oxidation stability and having extremely low evaporative losses compared to base oils obtained by refining crude oil.
- the viscosity characteristics of this GTL base oil should generally be a kinematic viscosity at 40° C. of 1.5 to 5.5 mm 2 /s, and preferably 1.98 to 2.42 mm 2 /s.
- the total sulfur content is generally less than 1 ppm, and the total nitrogen content is generally less than 1 ppm.
- SHELL GTL Solvent GS250TM is one example of this type of GTL base oil.
- This ⁇ -dithiophosphorylated propionic acid is a compound such as that represented by formula 1 below.
- R 1 represents a branched alkyl group having 3 to 8 carbon atoms
- R 2 represents a hydrogen atom or an alkyl group having 1 to 4 carbon atoms.
- R 1 can be a branched alkyl group such as an isopropyl group, a branched butyl group, a branched pentyl group, a branched hexyl group, a branched heptyl group or a branched octyl group.
- R 2 can be a hydrogen atom, a methyl group, an ethyl group, a propyl group, a butyl group, or the like, but a methyl group is particularly preferred.
- this type of compound examples include 3-(O,O-diisopropyl-dithiophosphoryl)-propionic acid, 3-(O,O-diisopropyl-dithiophosphoryl)-2-methyl-propionic acid, 3-(O,O-diisobutyl-dithiophosphoryl)-propionic acid and 3-(O,O-diisobutyl-dithiophosphoryl)-2-methyl-propionic acid.
- the ⁇ -dithiophosphorylated propionic acid should be used at a quantity of 0.01 mass % or more and less than 2 mass % relative to the total quantity of the lubricating oil composition.
- This acidic phosphoric acid ester is a compound such as that represented by formula 2 below.
- m denotes an integer of 1 or 2
- R denotes a straight chain or branched chain saturated or unsaturated hydrocarbon having 6 to 22 carbon atoms.
- this acidic phosphoric acid ester examples include oleyl acid phosphate, stearyl acid phosphate and 2-ethylhexyl acid phosphate.
- the acidic phosphoric acid ester should be used at a quantity of 0.01 mass % or more and less than 2 mass % relative to the total quantity of the lubricating oil composition.
- This acidic phosphoric acid ester can be used in combination with the ⁇ -dithiophosphorylated propionic acid.
- This type of oxygen-containing organic compound that is a solubilizing agent is at least one type of compound selected from among alcohols, esters, ethers, ketones, aldehydes, carbonates and derivatives thereof.
- polyalkylene glycols are particularly preferred.
- These polyalkylene glycols are compounds in which a plurality of alkylene glycols are polymerised, and are represented by formula 3 and formula 4 below, but are not particularly limited thereto.
- n is an integer between 2 and 4 and a is an integer.
- p and q are each an integer between 2 and 4, and s and t are both integers, but cannot both be 0).
- This PAG is a material having low oil solubility, and is therefore preferably at least one type of compound selected from among the group consisting of polyethylene glycol, polypropylene glycol and polybutylene glycol.
- the weight average molecular weight of the PAG is 200 to 10,000, preferably 200 to 6000, and more preferably 200 to 4000.
- weight average molecular weight is less than 200, solubility in the base oil is improved, but evaporative properties deteriorate, whereas if the weight average molecular weight exceeds 10,000, solubility in the base oil deteriorates.
- This PAG is a substance having low oil solubility, as mentioned above, and should therefore be contained at a quantity of 0.01 to 10.0 mass %, preferably 0.1 to 5.0%, and more preferably 0.1 to 3.0% relative to the total quantity of the lubricating oil composition.
- a variety of publicly known additives such as amine-based or phenol-based antioxidants, rust inhibitors, steric stabilizers, viscosity modifiers, dispersing agents, pour point depressants and anti-foaming agents, can be blended as appropriate in the lubricating oil composition of the present invention.
- the lubricating oil composition for a main shaft of a machine tool of the present invention will now be explained in greater detail through the use of working examples, comparative examples and base oil examples, but is in no way limited to these examples.
