Definitions
- the present invention relates to a lubricating oil composition. More specifically, the present invention relates to a lubricating oil composition to which a fluorine-containing organophosphorus compound is added to improve abrasion resistance and anti-corrosion properties of a mating material.
- Fluorine-containing organophosphorus compounds are known to have good effects of improving solvent resistance, chemical resistance, mold release, abrasion resistance, and friction resistance. Compounds are used for applications such as release agents and additives.
- fluorine-containing organophosphorus compounds are phosphoric acid ester type or phosphonic acid ester type having a linear perfluoroalkyl group, but oils such as perfluoropolyether oil, trifluorochloroethylene polymer oil, etc. Due to poor compatibility with water, its use in oils and greases is limited.
- JP-A-6-136379 describes a phosphoric ester type having a perfluoropolyester group, which dissolves in fluorine oil and has excellent lubricity. Hydrogen-containing groups and phosphoric acid groups form a C-0-P bond, which tends to cause hydrolysis, resulting in poor heat resistance and durability. The heat resistance cannot be exhibited. Disclosure of the invention
- An object of the present invention is a lubricating oil composition to which a fluorine-containing organic phosphorus compound is added, which has improved abrasion resistance, mackerel resistance, etc., without impairing the heat resistance inherent in fluorine oil and fluorine grease.
- An object of the present invention is to provide a perfluoropolyether base oil having a general formula
- Perfluoropolyether base oil has the general formula
- Rf a perfluoroalkyl group having 1 to 3 carbon atoms p, q, r: 0 or a positive integer
- perfluoropolyether base oils can be used alone or as a mixture, but when used as a lubricating oil or grease, the viscosity (JIS K-2283; 40 ° C) of about 5 to; 1500 thighs 2 / sec, preferably about 10-: 1500 thighs 2 / sec is desirable.
- Those with a viscosity less than this have a large amount of evaporation, and are specified by three types of grease for JIS rolling bearings required for heat-resistant grease. Will not satisfy the condition of the amount of evaporation (1.5% or less).
- the pour point JIS K-2283
- the bearing will not rotate at the time of low temperature startup in the normal method, and heating will be required to make it usable. Therefore, it is not suitable for use as a general grease.
- the perfluoropolyether group (Rf) of phosphonic acid or its ester which is a fluorine-containing organic phosphorus compound added to these perfluoropolyether base oils, has the general formula
- the OR 'group is preferably a hydroxyl group, a lower alkoxyl group or a perfluoro lower alkoxyl group.
- phosphonic acids or esters thereof are used in such a proportion that they occupy 0.1 to 20% by weight, preferably 0.5 to 5% by weight in the composition.
- Such a ratio is used in the grease composition to which the thickener is added. If the addition ratio is lower than this, the desired effect required for the lubricant cannot be obtained, while if it is used at a higher ratio, the performance corresponding to the cost performance cannot be obtained.
- the weight starts to decrease from about 150 ° C, but even at 250 ° C, about 50 ° remains, whereas for the corresponding phosphate ester, the weight starts to decrease from about 75 ° C, Furthermore, the thermal analysis results show that the temperature rapidly decreases from about 170 ° C and completely disappears at about 225 ° C, confirming the heat resistance of the phosphonate ester.
- the lubricating oil composition comprising each of the above components can be sufficiently used as a fluorine oil, but can be effectively used as a grease in consideration of sealing properties. In this case, a thickener is added to this.
- thickener examples include polytetrafluoroethylene (PTFE), tetrafluoroethylene-hexafluoropropene copolymer (FEP), tetrafluoroethylene-perfluoro (alkyl vinyl ether) copolymer, and tetrafluoroethylene- Organic resins such as ethylene copolymers, fluorine resins such as polyvinylidene fluoride, metal (composite) soaps such as Li, Ca, Ba, and Al, clays such as silica and benton, polyamides, polyimides, polypropylene, polyethylene, and polyurea Molecular substances and the like are used.
- PTFE polytetrafluoroethylene
- FEP tetrafluoroethylene-hexafluoropropene copolymer
- alkyl vinyl ether alkyl vinyl ether copolymer
- tetrafluoroethylene- Organic resins such as ethylene copolymers, fluorine resins such as
- thickeners are used in the grease composition in an amount of about 1 to 50% by weight, preferably about 3 to 35% by weight. If the addition ratio is less than this, the grease easily leaks, and the grease's original function of sealing cannot be exhibited. On the other hand, if it is used at a higher ratio, the grease composition becomes too hard, so that sufficient lubricity cannot be exhibited.
- an antioxidant per 100 parts by weight of the grease composition, for example, 2,6-ditert-butyl-4-methylphenol, 4, V-methylenebis Phenolic compounds such as (2,6-ditert-butylphenol), alkyldiphenylamines (alkyl groups having 4 to 20 carbon atoms), triffe
- amine antioxidants such as nilamine, phenyl-hy-naphthylamine, phenothiazine, alkylated phenyl-hy-naphthylamine, phenylthiazine, and alkylated phenothiazine alone or in combination of two or more.
- the lubricating oil composition is prepared by adding a phosphonic acid or its ester, a fluorine-containing organic phosphorus compound, to a perfluoropolyether base oil and mixing and dissolving it simply by stirring. be able to.
- a phosphonic acid or its ester a fluorine-containing organic phosphorus compound
- a perfluoropolyether base oil a perfluoropolyether base oil
- mixing and dissolving it simply by stirring be able to.
- the following preparation method is employed for the grease composition.
- the thickening agent is a metal (composite) soap
- a perfluoropolyether base oil and a fatty acid are added to a reaction vessel capable of heating and stirring, and dissolved by heating.
- Specimen SUJ2 (l / 2 inch), 20 class, number of rotations: 20 times / sec, load: 392.3N (40kgf), temperature: room temperature, time: 60 minutes using a seal four-ball testing machine The test was performed, and the diameter of the wear scar after the test was measured.
- a wet test specimen (material: SPCC-SB, dimensions: 1.2x60x80) is immersed in the lubricating oil composition, and temperature: 49 ⁇ 1 ° Humidity: suspended in a test machine tank of 95% or more for 100 hours Hold. After the test is completed, remove the test piece and check the degree of occurrence of mackerel. The degree of occurrence is indicated by the grade described below.
- ⁇ Occurrence II
- the lubricating oil composition and the grease composition according to the present invention have improved abrasion resistance and anti-blue property without deteriorating the heat resistance inherent in the fluorine oil and the fluorine grease.
