Description
Technical Field
The present invention relates to a grease composition and the like for imparting an optimum lubricating effect to a sliding portion of a resin material, particularly a polypropylene resin member.
Background
In general, as a lubricant used for a resin sliding portion of an in-vehicle component, grease containing various base oils has been proposed. For example, greases using a metal soap such as a lithium soap or a lithium complex soap, a solid lubricant such as polytetrafluoroethylene as a thickener, synthetic hydrocarbon oil, mineral oil, fluorine oil, silicone oil, or the like as a base oil, and optionally an antioxidant, a rust preventive, or the like are often used.
In particular, as a grease for resin having a low friction coefficient or a low torque, a grease containing various waxes has been proposed. For example, a grease which is excellent in low friction at a lubrication part and high durability by blending a mineral oil or a hydrocarbon-based synthetic oil as a base oil, a urea-based thickener and montan wax as a thickener in the base oil has been proposed (see japanese unexamined patent publication (kokai) No. 2002 371290). The grease is preferably used for a resin having an acid or acid derivative group and a polar group, such as a polyamide resin (nylon) or a polybutylene terephthalate resin. Although there is a concern that the grease using mineral oil or synthetic hydrocarbon oil as the base oil may cause swelling or cracking of the resin member, the synthetic oil grease of patent document 1 eliminates the risk of the above-mentioned partial resin.
On the other hand, when an ester or ether oil is used as the base oil, there is a risk of affecting the resin member, and it is preferable not to use it as the base oil or the main component (for example, refer to japanese patent application laid-open No. 2002-363589).
Neither of jp 2002-371290 and jp 2002-363589 describes whether or not there is an influence on a polypropylene resin as a representative crystalline resin, and does not eliminate the concern about the resin compatibility (swelling/dissolution, etc.) of the synthetic oil grease with respect to polypropylene. In addition, synthetic oil greases are generally sensitive to temperature changes, and in many cases have poor physical stability in low temperature environments. Therefore, improvements are also desired in this regard.
On the other hand, as the grease excellent in resin resistance and temperature characteristics, a fluorine oil grease is exemplified. Although the fluorine oil grease can be used for all resins and can be used in a wide temperature range, it is difficult to impart various functions (e.g., rust preventive function) by additives. Therefore, the rust inhibitive performance is inferior to that of a synthetic oil grease to which the additive can impart a function. But also expensive.
Next, as a grease excellent in resin resistance and temperature characteristics, a silicone oil grease is also exemplified. However, in the case of silicone oil, it is inherently difficult to obtain a low friction purified product, and it is also difficult to impart a rust-preventive function because a liquid petroleum additive is hardly dissolved. In particular, when the low molecular weight component of the silicone oil contained in the silicone oil grease volatilizes and adheres to the contact portion, there is a risk of poor current conduction due to formation of an insulator. As a result, it is difficult to apply the present invention to vehicle-mounted components requiring electrical safety.
Disclosure of Invention
Problems to be solved by the invention
The purpose of the present invention is to provide a grease composition or the like which has material compatibility with a crystalline resin such as polypropylene or the like even in the case of a synthetic oil grease, can be used in a wide temperature range from high temperatures to low temperatures, and has excellent low-temperature characteristics.
Means for solving the problems
As a result of intensive studies to solve the above problems, the present inventors have found that the kinematic viscosity at 40 ℃ is 100mm2When a polyalkyl alcohol or a polyalkylene alcohol (hereinafter referred to as "multimolecular hydrocarbon alcohol") having a viscosity of at most s is used as the base oil, the synthetic oil grease containing the thickener has material compatibility with a crystalline resin such as polypropylene, can be used in a wide temperature range from high temperatures to low temperatures, and has excellent low-temperature characteristics. Thus, in the present grease composition, the shear stress at-40 ℃ is less than 9000Pa, and low torque properties can be achieved. When the shear stress at-40 ℃ in a low-temperature environment exceeds 9000Pa, an increase in torque at the time of actual use is unavoidable, and energy loss due to friction increases, and thus the steel is not suitable for actual use.
Further, by using the above-mentioned polyhydric hydrocarbon alcohol as the base oil, functions can be imparted by various additives used in the synthetic oil grease, and in particular, a rust preventive agent can be added, so that it can be used in combination with a metal member, a metal contact, or the like.

Detailed Description
A grease composition according to an embodiment of the present invention will be described. In the present grease composition, a multimolecular hydrocarbon alcohol is used as the base oil. The term "multimolecular hydrocarbon alcohol" is specifically defined as at least one of a polyalkyl alcohol and a polyalkylene alcohol. For example, it can be produced by polymerizing an alkyl alcohol or an alkylene alcohol. The alkyl group or alkylene group in the polyhydric hydrocarbon alcohol may be optionally straight-chain or branched, and the number of main chains (carbon number) n is preferably 2 to 5. For example, the representative examples include an ethyl group, a propyl group, a butyl group, and a pentyl group in the case of a linear alkyl group, and an ethylene group, a propylene group, a butylene group, and a pentylene group in the case of a linear alkylene group. In the case of a branched chain, one or more hydrogen atoms of the above-mentioned linear alkyl group or alkylene group are typically substituted with an alkyl group such as a methyl group, an ethyl group, an n-propyl group, an isopropyl group, an n-butyl group, an isobutyl group, or a tert-butyl group.
In addition, the alkyl group or alkylene group as the main chain of the multimolecular hydrocarbon alcohol used as the base oil in the grease composition has a polymer (low molecular polymer or high molecular polymer such as dimer, trimer or oligomer), and more preferably has a low molecular polymer structure. Examples thereof include a monohydric alcohol type having one alcohol group at the end of the main chain of the polyhydric hydrocarbon alcohol, a dihydric alcohol type having two alcohol groups, a polyhydric alcohol type having three or more alcohol groups, and the like, and the number thereof may be any. The number of the multi-molecular hydrocarbon-based alcohols is not limited to one, and a plurality of kinds may be used in combination.
The used multi-molecular hydrocarbon alcohol has a kinematic viscosity of 100mm at 40 deg.C2The ratio of the water to the water is less than s. The grease composition is produced by adding a thickener to the multimolecular hydrocarbon alcohol.
The grease composition can be adjusted so that it has a shear rate of 30s at-40 deg.C-1The shear stress at that time is 9000Pa or less.

As the thickener used in the grease composition of the present embodiment, a known thickener can be used. For example, fluororesin systems, melamine cyanurate, metal soaps, and the like can be used. As the fluororesin, any one or two of PTFE, PVDF, PVF (homopolymer group), and a fluororesin copolymer (e.g., PTFE copolymer, PFA, FEP, ETFE, ECTFE) are preferable. PTFE or PTFE as the main component is particularly preferable. When used in the present embodiment, the average particle size is preferably 0.1 to 30 μm. In this case, the weight ratio of the fluororesin to the multimolecular hydrocarbon alcohol as the base oil is preferably in the range of 2: 8-5: 5, in the above range. The amount of the fluororesin contained in the grease obtained by using the grease composition is preferably 5 to 50% by mass, more preferably 10 to 40% by mass. Examples of the fluorine resins include commercially available KTL, KT-300M of KT series, KTL-400M, KTL-600M, KTL-450, KTL-610, KTL-620, KTL-20N, KTL-10N, KTL-8N, KTL-4N, KTL-2N, KTL-8F, KTL-500F (manufactured by Xyomura corporation), Dry film RA, RA/IPA, RA/W, RA/IPA, 2000/IPA, LW-1200 (manufactured by Kemmo corporation, ケマーズ), DYNEON (registered trademark) 1700, TF1705, TF1750, TF9201Z, TF9205, TF9207Z (manufactured by 3M Japan Co., Ltd.), Ceal Lufbe (セフラルルーブ) (registered trademark) I, TF (manufactured by Japan Kagaku corporation, セントラル), Alpolynitro (アルゴフロン) (registered trademark) I, Katsubishi (manufactured by Japan Katsui corporation, Kogyoki Katsuba Kaisha), Katsuba (Katsuba (Katsuba (Ka, The same examples as those of L101-1, L106, L203, L206, L600, Polymist (ポリミスト) (registered trademark) F284, F5A, F5AEX, XPP511, XPP515, XPP535, XPP538, XPP552 (manufactured by Nippon Seisakusho K.K.

Note that a part of the fluororesin may contain perfluorooctanoic acid (PFOA) and its salt and a PFOA-related substance (hereinafter referred to as perfluorooctanoic acid or the like). Due to the revision of the REACH (chemical registration, evaluation, approval, and restriction) restricted subject matter by EC (european commission), the production and marketing of perfluorooctanoic acid and the like may be prohibited in the future. As a method for producing the perfluorooctanoic acid-free product, for example, there are polymerization methods such as bulk polymerization, suspension polymerization, precipitation polymerization, emulsion polymerization, and solution polymerization, and methods for removing the perfluorooctanoic acid by treatment after the polymerization, but in the present embodiment, the perfluorooctanoic acid-free product can be used regardless of whether it contains PFOA or not.
The melamine cyanurate is a white powder composed of an addition product of melamine and cyanuric acid. In the case of use in the present embodiment, the average particle diameter is preferably 30 μm or less. Specifically, melamine cyanurate ProFlame-MC15, MC25 (manufactured by Novista corporation, ノヴィスタ), MC-4000, MC-4500, MC-6000 (manufactured by Nissan chemical industries), MELAPUR (registered trademark) MC25, and melamine cyanurate 200/70 (manufactured by Pasteur corporation) can be cited.
As the metal soap-based thickener, a thickener comprising a metal carboxylate can be used. As the carboxylic acid, a carboxylic acid derivative having a hydroxyl group or the like can be used. The carboxylic acid may be an aliphatic carboxylic acid such as stearic acid or azelaic acid, or an aromatic carboxylic acid such as terephthalic acid. Preferably a monovalent aliphatic carboxylic acid having 12 to 20 carbon atoms or a divalent aliphatic carboxylic acid having 6 to 14 carbon atoms. Most preferred are monovalent aliphatic carboxylic acids containing one hydroxyl group. The metal is preferably an alkali metal such as lithium or sodium; alkaline earth metals such as calcium; amphoteric metals such as aluminum. In particular, lithium is preferably used.
The content of these thickeners can be arbitrarily adjusted. For example, when melamine cyanurate is used, the content weight of the melamine cyanurate is the same as or less than the weight of the base oil, i.e., the weight of the base oil. Specifically, when the total weight of the polyvalent hydrocarbon alcohol and the melamine cyanurate is 100% by weight, the amount of the melamine cyanurate is preferably 5 to 50% by weight, more preferably 10 to 40% by weight. When both a fluororesin and melamine cyanurate are used as the thickener, the total content of both is the same as or less than that of the base oil, i.e., the base oil. Specifically, when the total weight of the multimolecular hydrocarbon alcohol and the thickener (melamine cyanurate and fluororesin) is 100% by weight, the amount of the thickener (melamine cyanurate and fluororesin) is preferably 5 to 50% by weight, more preferably 10 to 50% by weight, still more preferably 10 to 40% by weight, and still more preferably 20 to 40% by weight.
In addition, in the case where a metal soap is used as the thickener, the weight ratio of the metal soap to the polyhydric hydrocarbon-based alcohol as the base oil is preferably 5: 95-50: 50, or less. When the total amount of the grease composition is 100 wt%, it is preferably 5 to 20 wt%. Further, in the case where both a fluororesin and a metal soap are used as the thickener, the weight ratio of the total weight of the thickener (the fluororesin and the metal soap) to the multi-molecular hydrocarbon-based alcohol as the base oil is in the range of 1: 9-5: 5, in the above range. In addition, in the case where both melamine cyanurate and a metal soap are used as the thickener, the weight ratio of the total weight of the thickener (melamine cyanurate and metal soap) to the multi-molecular hydrocarbon-based alcohol as the base oil is in the range of 1: 9-5: 5, in the above range.
When the amount of these thickeners added is too small, the resulting grease-like material tends to be unable to obtain a predetermined consistency. If too much, the low temperature characteristics of the grease tend to deteriorate.
In the present embodiment, it is desirable that the range of consistency be, in the NLGI scale, the range of consistency No. 2 (280 ± 15) from consistency No. 1 (325 ± 15) to consistency No. 3 (235 ± 15). When the consistency is too low, an increase in viscous resistance and an increase in torque cannot be avoided. In addition, when the consistency is too high, it becomes difficult to stably fix the grease to the coated surface.
The grease composition of the present embodiment is a composition in which the base oil of each component described above is blended with a thickener, and various additives can be appropriately blended as necessary. For example, antioxidants, extreme pressure agents, rust inhibitors, metal deactivators, metal detergents, oiliness improvers, friction and wear reducers, viscosity index improvers, pour point depressants, surfactants, conductive agents, antifoaming agents, colorants, and the like.
For example, as the antioxidant, a phenol compound, an aromatic amine compound, or the like can be used.
As the extreme pressure agent, olefin sulfide, sulfurized fats and oils, methyl trichlorostearate, naphthalene chloride, benzyl iodide, fluoroalkyl polysiloxane, lead naphthenate, and the like can be used.
Examples of the rust inhibitor include carboxylic acids such as stearic acid, dicarboxylic acids, metal soaps, amine carboxylates, metal salts of heavy sulfonic acids, and carboxylic acid partial esters of polyhydric alcohols.
As the metal deactivator, benzotriazole, benzimidazole, or the like can be used, and as the metal detergent, alkaline earth metal sulfonate, alkaline earth metal phenol ester, alkaline earth metal salicylate, or the like can be used.
As the oiliness improver, fatty acid, aliphatic alcohol, ester, fat and oil, and the like can be used.
As the friction wear reducing agent, zinc, sulfur, phosphorus, amine, ester, or the like can be used.
As the viscosity index improver, a polymethacrylate, an ethylene-propylene copolymer, a styrene-isoprene copolymer, a hydrogenated product of a styrene-isoprene copolymer, polyisobutylene, or the like can be used.
As the pour point depressant, polyalkylacrylate, polybutene, polyalkylstyrene, polyvinyl acetate, etc. can be used.
As the surfactant, a sulfonate, an amine sulfate salt, an aliphatic amine salt, an aliphatic ammonium salt, a sorbitan fatty acid ester, a polyoxyethylene glycol ester, or the like can be used.
As the conductive agent, graphite, metal powder, or the like can be used. As the defoaming agent, silicone oil or the like can be used. As the colorant, various pigments, dyes, and the like can be used.
The grease composition of the present embodiment may further contain a known solid lubricant. As the solid lubricant, various substances such as boron nitride, molybdenum disulfide, graphite, fluorine-containing copolymer, and the like can be used. These may be used alone or in combination of two or more. The average particle size of these solid lubricants is preferably about 30 μm as in the case of the thickener.
In addition to the solid lubricant, an inorganic filler, an organic filler, or the like may be added to impart functions such as conductivity and vibration-proof effect. As the inorganic filler, known ones such as metal oxides, metal sulfides, sulfur oxides, carbon oxides, nitrides, carbides, corundum, and artificial diamond can be used. As the organic filler, fine particles of various resin or rubber components can be used. In addition, a hybrid of inorganic and organic materials or a complex structure can also be suitably used.
The grease composition of the present embodiment can be obtained as a complex base oil type grease composition by mixing and using a fluorine grease according to the use. The "plural base oil type" refers to a hybrid type grease composition containing a multimolecular hydrocarbon alcohol and a base oil of a type other than the multimolecular hydrocarbon alcohol. The mixing ratio can be arbitrarily changed depending on the application. In particular, in the case of a complex base oil type grease composition, a better effect can be obtained by selecting a metal soap as a thickener thereof. This is because the metal soap is suitable as a thickener for both the grease composition of the present embodiment, which uses a multimolecular hydrocarbon alcohol as a base oil, and the fluorine grease.
The grease composition of the present embodiment or the complex base oil type grease composition can be produced by a usual method. For example, a method of adding a base oil, a thickener and appropriate additives, and kneading and dispersing the mixture as necessary is exemplified. The kneading and dispersion can be carried out by using a known roll MILL, colloid MILL, ball MILL, nano sand MILL (DYNO-MILL, ダイノーミル), or the like.
The grease composition or the multiple base oil type grease composition according to the present embodiment may be diluted with an appropriate organic solvent and used. In the present embodiment, this is defined as a lubricant composition (or a grease diluting liquid). As the organic solvent, general solvents can be widely used, and particularly, hydrocarbon-based or fluorine-based solvents are preferable.
Examples of the hydrocarbon solvent include acetone, methanol, ethanol, n-propanol, isopropanol, Petroleum naphtha (Petroleum benzin), Petroleum ether, ligroin (ligroin, リグロイン), methyl acetate, ethyl acetate, butyl acetate, isobutyl acetate, toluene, xylene, benzene, tetrahydrofuran, tetrachloroethylene, dichloroethane, 1,1, 1-trichloroethane, ethylene glycol monomethyl ether, methyl ethyl ketone, diethyl ether, dibutyl ether, and the like. One or a mixture of two or more of these solvents can be used for dilution.
Examples of the fluorine-based solvent include perfluorocarbon, hydrofluorocarbon, hydrofluorocarbonchlorocarbon, hydrofluoroether, perfluoropolyether, hydrofluoroolefin, and hydrofluorochloroolefin. One or a mixture of two or more of these solvents can be used for dilution.
The hydrocarbon-based solvent and the fluorine-based solvent may be mixed at an arbitrary ratio according to the application or the coating method. In addition, the solvent may be mixed with a water-soluble solvent such as alcohol or glycol.
The resin member to which the grease composition, the complex base oil type grease composition, or the grease diluting liquid of the present embodiment is applied is not particularly limited as long as it is a crystalline resin. Here, the crystalline resin means a resin having a large proportion of crystal sites in the resin component. The crystallized resin has a glass transition point and has a large molding shrinkage rate due to crystallization after molding. Specific examples thereof include polyethylene, polypropylene, polyamide, polyoxymethylene, polybutylene terephthalate, and polyphenylene sulfide. However, among these resins, a resin having a relatively large amount of a component which becomes a crystalline portion is more preferable, and a resin which is not a blend with a rubber component or an amorphous resin is preferable. The present embodiment is particularly preferably applied to polypropylene having high versatility as a crystalline resin member.
For example, the present invention is applicable to various members requiring self-lubrication, low-temperature characteristics, and the like, such as a slide rail sliding portion, a gear, a bearing, and an electrical contact of a precision device. The grease composition, the complex base oil type grease composition, or the grease diluting liquid according to the present embodiment can be applied to moving bodies such as automobiles, bicycles, and electric cars; crystalline resin parts such as audio/video equipment and information equipment; between the resin member and the metal member or the metal member; and a sliding portion of a member using ceramics. That is, although a general resin has weak resistance to an oil component in grease, the present invention can be applied to a sliding portion made of a crystalline resin.
The grease composition, the multiple base oil type grease composition, or the grease diluted solution according to the present embodiment can be formed into a lubricating film by a general method. Specifically, the lubricating film can be formed on the sliding member and the portion thereof by a method of coating the sliding member with a grease composition, a complex base oil type grease composition, or a grease diluting solution using a brush, a spray, or a dispenser, a method of immersing the sliding member in a grease composition, a complex base oil type grease composition, or a grease diluting solution, or the like.
The coating amount on the sliding member can be adjusted appropriately according to the position, and the thickness of the coating film is preferably about 0.1 to 3000 μm.
When the grease composition, the multiple base oil type grease composition or the grease diluted solution has a thick coating film or is applied in a large amount, these components exude from the sliding member, and adversely affect other members, which is not preferable. In addition, when the coating film is thin or the coating amount is small, these components are depleted, and an appropriate lubricating effect cannot be obtained.
The present invention will be specifically described below based on examples. However, the present invention is not limited thereto.

From the above results, it is understood that in the grease composition and the grease diluted solution within the range of the present example, the shear stress at low temperature can be stably maintained at 9000Pa or less, and no adverse effect on the polypropylene resin is observed. Thus, a grease composition and a grease diluted solution which are suitable for use with crystalline resins such as polypropylene even in hydrocarbon-based greases and have excellent low-temperature characteristics can be provided.
On the other hand, as shown in the results of comparative examples, it was difficult to maintain the state of the grease at low temperature in the compositions and base oil materials other than those of the present examples, and the shear stress could not be measured. In addition, it is inevitable that base oils other than polyalkyl alcohols affect polypropylene.
The grease composition of the present invention can additionally exhibit various functions by adding any additives and the like. As an example, in the compositions of examples 1 to 31 in which the antioxidant was added, the rust preventive effect on iron in the brine immersion was further confirmed in addition to the sufficient effect. This makes it possible to use the lubricant for lubrication and rust prevention of metal parts, and to use the lubricant as a lubricant suitable for both resins and metals. Conventionally, in the case of using the present invention for a composite member of a metal and a crystalline resin, it is necessary to use a lubricant for each material or to coat the composite member with a mask separately. As described above, the present invention can be extended to a part, a new field, or a commercial product, which has been difficult to use, by providing a function.
Further, since the grease is derived from a synthetic oil, it can be diluted and dispersed in various general solvents, and can be used as a quick-drying lubricant and also for film coating.
As described above, the present invention can provide a grease composition and a grease dilution that can be widely used. The present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the scope of the present invention.
