Definitions
- the present invention relates to a silicone composition. More particularly, the invention relates to a silicone grease composition suitably used for the parts to be lubricated, to be more specific, the lubrication parts of the clutch, the torque limiter mechanism and the like where high coefficient of friction and excellent wear preventive characteristics are needed.
- the clutch of the engine starter is composed of a clutch outer, a clutch inner, a roller disposed in a wedge-like space formed between the clutch outer and the clutch inner to transmit the rotation of the clutch outer to the clutch inner, and a spring which works to urge the roller toward the narrower side of the wedge-like space.
- the roller moves toward the narrower side of the wedge-like space and is then caught between the clutch outer and the clutch inner, thereby transmitting the rotation to the clutch inner (torque-transmitted state). Accordingly, the grease composition used for such portions requires a high coefficient of friction to prevent the slippage of the clutch outer, the clutch inner and the roller.
- silicone grease compositions are conventionally known: a grease for the overrunning clutch ( JP (Hei) 7-35824 B ) where a base oil comprising a silicone oil has a coefficient of friction of 0.18 or more; grease compositions ( JP (Hei) 5-230486 A and JP (Hei) 6-279777 A ) comprising as the base oil organopolysiloxanes having a predetermined ratio of phenyl group or methyl group; and a traction grease composition ( JP 2003-176489 A ) comprising finely-divided particles of metallic oxide, a thickener, and a base oil containing a dimethyl silicone oil with a predetermined kinematic viscosity in an amount of 1 to 40 mass%.
- Those grease compositions make use of the advantages of the silicone oils that the coefficients of friction are high, and in addition, the surface tensions of the silicone oils range from 20 to 25 dyn/cm2, which are lower than those of other oils, so that a lubrication film may not readily be formed, thereby easily attaining to boundary lubrication.
- the clutch and the torque limiter mechanism are required to be smaller in size and lighter in weight in line with the recent tendency toward weight reduction in the automobile, and on the other hand, they are exposed to severer operating conditions. Especially, satisfactory torque transmission properties are demanded even when the operating conditions become more and more tough. For that reason, the grease composition is required to have a higher coefficient of friction. At the same time, the wear preventive characteristics are also needed when the grease composition is used for the clutch and the torque limiter mechanism.
- an object of the invention is to provide a silicone grease composition having improved frictional characteristics, without deterioration of the wear preventive characteristics.
- the inventors of the present invention contrived a grease composition having an increased coefficient of friction without decrease of the wear preventive characteristics by adding as the friction modifier a metallic oxide with a Mohs hardness of 6 or less.
- the invention provides a grease composition as shown below.
- a silicone grease composition where the frictional characteristics are improved without decrease of the wear preventive characteristics can be provided.
- a silicone oil is used for the base oil in the grease composition according to the invention.
- silicone oil examples include dimethyl silicone oil, methylphenyl silicone oil (phenyl-modified silicone oil), methyl hydrogen silicone oil, polyether-modified silicone oil, aralkyl-modified silicone oil, fluoroalkyl-modified silicone oil, alkyl-modified silicone oil, fatty acid ester-modified silicone oil, and the like.
- dimethyl silicone oil and methylphenyl silicone oil are preferably used.
- the silicone oil represented by the following general formula (1) is particularly preferable: (CH 3 ) 3 SiO-[-Si(R1)(R2)-O-]n - Si(CH 3 ) 3 (1) wherein R1 and R2 are each independently methyl group or phenyl group, the ratio of methyl group to the whole organic groups being 50 to 100 mol.%.
- the kinematic viscosity of the silicone oil is not particularly limited, but may preferably be in the range of 20 to 10,000 mm 2 /s, more preferably 50 to 2,000 mm 2 /s at 25°C.
- the kinematic viscosity of the silicone oil is less than 20 mm 2 /s, the base oil may easily separate from the grease.
- the kinematic viscosity exceeds 10,000 mm 2 /s, the torque will increase at low temperatures due to the viscosity resistance. In any case, the results are practically undesirable.
- R1 and R2 are each independently methyl group or phenyl group, the ratio of the methyl group to the whole organic groups being 50 to 100 mol.%.
- the ratio of the methyl group to the whole organic groups may preferably be 60 to 100 mol.%, more preferably 80 to 98 mol.%, and still more preferably 90 to 95 mol.%.
- the silicone oil may preferably be contained in an amount of 55 to 90 mass%, and more preferably 70 to 90 mass%, with respect to the total mass of the composition. Such a content of the silicone oil can favorably lead to high coefficient of friction.
- the silicone oil may be used in combination with other base oil components so long as the performance of the silicone oil may not be impaired.
- One or more base oil components selected from the group consisting of mineral oils, poly ⁇ -olefins, polybutene, alkylbenzene, animal and vegetable oils, organic acid esters, diesters, polyol esters, polyalkylene glycols, polyvinyl ethers, polyphenyl ethers, and alkylphenyl ethers can be used.
- the amount of other base oil component(s) that can be used in combination with the silicone oil may preferably be 0 to 50 mass% with respect to the mass of the silicone oil used for the base oil.
- the amount of other base oil component(s) may preferably be 0 to 20 mass%, more preferably 0 to 10 mass%, with respect to the mass of the lubricating base oil used in the invention. It is most preferable to use no other base oil component.
- the thickener used for the grease composition of the invention is not particularly limited. Specific examples include soap type thickeners such as lithium soaps and lithium complex soaps, urea type thickeners such as diurea compounds, inorganic thickeners such as organoclay and silica, organic thickeners such as polytetrafluoroethylene and melamine cyanurate, and the like. At least one selected from the above-mentioned group may be used. It is preferable to select from the group consisting of silica, lithium soaps, lithium complex soaps and urea compounds. In particular, the urea compounds are preferable.
- diurea compounds are preferable, and in particular the diurea compounds represented by the following general formula (2) are preferred: R3-NHCONH-R4-NHCONH-R5 (2) wherein R3 and R5, which may be the same or different from each other, each represent a residue of monovalent hydrocarbon groups having 4 to 20 carbon atoms, for example, aliphatic hydrocarbon groups, alicyclic hydrocarbon groups and aromatic hydrocarbon groups; and R4 is a bivalent aromatic hydrocarbon group having 6 to 15 carbon atoms.
- the above-mentioned diurea thickener can be obtained by reacting a predetermined diisocyanate with a predetermined monoamine in the base oil, for example.
- a predetermined diisocyanate include diphenylmethane-4,4'-diisocyanate and tolylene diisocyanate.
- the monoamine include aliphatic amines, aromatic amines and alicyclic amines, or the mixtures thereof.
- Specific examples of the aliphatic amines include octylamine, dodecylamine, hexadecylamine, octadecylamine, and oleylamine.
- Specific examples of the aromatic amines include aniline and p-toluidine.
- alicyclic amines include cyclohexylamine.
- cyclohexylamine, octylamine, dodecylamine, hexadecylamine, octadecylamine, or the mixture thereof may preferably be used for preparation of the diurea thickener.
- alicyclic aliphatic diurea compounds are preferred which can be obtained by using cyclohexylamine together with octylamine, dodecylamine, hexadecylamine, octadecylamine or the mixture thereof.
- alicyclic aliphatic diurea compounds obtained from cyclohexylamine and octadecylamine, or the mixtures thereof are particularly preferable.
- a mixture of the following three kinds of diurea compounds represented by formula (2-1), (2-2) and (2-3) (where R is octadecyl group) is most preferable.
- the content of the thickener which may appropriately be adjusted in accordance with the desired consistency is generally 2 to 35 mass%, preferably 5 to 30 mass%, and more preferably 10 to 25 mass%.
- the resultant product becomes a liquid, which cannot be used as a grease.
- the content of the thickener exceeds 35 mass%, the resultant grease is not practically desirable because the grease is so hard that the torque will increase at low temperatures.
- the grease composition of the invention comprises as the friction modifier a metallic oxide with a Mohs hardness of 6 or less.
- the addition of the metallic oxide as the friction modifier can increase the coefficient of friction because the oil film becomes easy to break due to the metallic oxide entering into the surfaces to be lubricated. Even when the lubrication member is made of steel, use of the metallic oxide with a Mohs hardness of 6 or less can increase the coefficient of friction, with damage to the steel being minimized.
- magnesium oxide, potassium oxide, calcium oxide, scandium oxide, titanium oxide, vanadium oxide, chromium oxide, manganese oxide, iron oxide, cobalt oxide, nickel oxide, copper oxide, zinc oxide, gallium oxide, germanium oxide, strontium oxide, yttrium oxide, zirconium oxide, niobium oxide, molybdenum oxide, technetium oxide, ruthenium oxide, rhodium oxide, palladium oxide, silver oxide, indium oxide, tin oxide, antimony oxide, tellurium oxide, barium oxide, hafnium oxide, tantalum oxide, tungsten oxide, rhenium oxide, lead oxide, and silicon oxide can be used.
- magnesium oxide, zinc oxide and molybdenum oxide are preferable.
- the Mohs hardness of the metallic oxide is preferably 6 or less, more preferably 2 to 6, and still more preferably 4 to 6.
- the Mohs hardness of more than 6 is not favorable because the abrasion will become harsh during the idling operation in the torque non-transmitted state.
- the metallic oxide may preferably have an average particle diameter of 10 ⁇ m or less, more preferably 5 ⁇ m or less, and still more preferably 2 ⁇ m or less. When the average particle diameter exceeds 10 ⁇ m, it becomes difficult for the metallic oxide particles to come between the surfaces to be lubricated, and therefore a sufficient effect cannot be expected.
- the BET conversion method by N 2 -adsorption may be used to determine the average particle diameter herein used.
- the metallic oxide may preferably be contained in an amount of 0.1 to 10.0 mass%, more preferably 0.3 to 7.0 mass%, still more preferably 0.5 to 5.0 mass%, and most preferably 1.0 to 3.0 mass%, based on the total mass of the composition.
- 0.1 mass% a sufficient effect cannot be expected.
- the content of the metallic oxide exceeds 10.0 mass%, the cost will be disadvantageous because the effect is saturated.
- auxiliary additives may be used alone or in combination.
- the auxiliary additives may be added if necessary, and in this case, the contents may be 0.01 to 10 mass% generally. However, the contents of those additives are not particularly limited as far as the effects of the invention are not degraded.
- the grease composition of the invention may preferably have a worked penetration of 200 to 400, more preferably 230 to 380, and most preferably 250 to 350.
- the silicone grease composition comprises; a mixture of three kinds of diurea compounds represented by the above-mentioned formulas (2-1), (2-2) and (2-3) as a thickener, a base oil consisting of the silicone oil represented by the above-mentioned formula (1), with no other base oil component being added, and magnesium oxide, zinc oxide or molybdenum oxide as a friction modifier.
