Description
本発明は、工業油組成物に関する。 TECHNICAL FIELD This invention relates to industrial oil compositions.
特許文献１には、基油として縮合リン酸エステルを含む難燃性潤滑油組成物が記載されている。具体的には、縮合リン酸エステルとしてビスフェノールＡビス（ジフェニルホスフェート）が用いられている。 Patent Document 1 describes a flame-retardant lubricating oil composition containing a condensed phosphate ester as a base oil. Specifically, bisphenol A bis(diphenyl phosphate) is used as the condensed phosphoric acid ester.
しかしながら、特許文献１の難燃性潤滑油組成物は、縮合リン酸エステルを含むため、他の鉱油または合成油を含む工業油組成物とは混ざり合わず、これら他の工業油組成物とは別に廃棄する必要がある。このように、取扱い性が悪いという問題がある。また、特許文献１の難燃性潤滑油組成物は、基油として縮合リン酸エステルを含むため、コストもかかるという問題がある。そこで、本発明の目的は、廃棄の際の取り扱いに優れており、コストも抑えられる工業油組成物を提供することにある。 However, since the flame-retardant lubricating oil composition of Patent Document 1 contains condensed phosphate ester, it does not mix with industrial oil compositions containing other mineral oils or synthetic oils, and is different from these other industrial oil compositions. Must be disposed of separately. As described above, there is a problem of poor handling. Furthermore, the flame-retardant lubricating oil composition of Patent Document 1 contains a condensed phosphate ester as a base oil, and therefore has the problem of being costly. SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide an industrial oil composition that is easy to handle at the time of disposal and is inexpensive.
本発明の工業油組成物は、基油として、トリメチロールプロパンエステル油および１００℃における動粘度が５ｃＳｔ以上であるパラフィン系炭化水素油から選ばれる少なくとも１種と、酸化防止剤として、下記式（Ｂ）で表される中性亜リン酸エステル誘導体および下記式（Ｃ）で表される２，６－ジ－ｔ－ブチルフェノール誘導体とを含む。 The industrial oil composition of the present invention contains, as a base oil, at least one selected from trimethylolpropane ester oil and paraffinic hydrocarbon oil having a kinematic viscosity of 5 cSt or more at 100°C, and, as an antioxidant, a neutral phosphite derivative represented by the following formula (B) and a 2,6-di-t-butylphenol derivative represented by the following formula (C).
（上記式（Ｂ）中、Ｒb21～Ｒb24は、それぞれ独立に、炭素原子数１０～１６の脂肪族炭化水素基を表し、Ｒb25～Ｒb28は、それぞれ独立に、炭素原子数１～６の直鎖もしくは分枝状のアルキル基を表し、Ｒb291およびＲb292は、それぞれ独立に、水素原子または炭素原子数１～５の直鎖もしくは分枝状のアルキル基を表し、Ｒb291およびＲb292の炭素原子数の合計は、１～５である。） (In the above formula (B), R b21 to R b24 each independently represent an aliphatic hydrocarbon group having 10 to 16 carbon atoms, and R b25 to R b28 each independently represent an aliphatic hydrocarbon group having 1 to 16 carbon atoms. 6 represents a straight chain or branched alkyl group, R b291 and R b292 each independently represent a hydrogen atom or a straight chain or branched alkyl group having 1 to 5 carbon atoms, and R b291 and The total number of carbon atoms in R b292 is 1 to 5.)
（上記式（Ｃ）中、Ｒc1は、炭素原子数１～１２の直鎖もしくは分枝状のアルキル基である。） (In the above formula (C), R c1 is a linear or branched alkyl group having 1 to 12 carbon atoms.)
本発明の工業油組成物は、廃棄の際の取り扱いに優れており、コストも抑えられる。 The industrial oil composition of the present invention is excellent in handling at the time of disposal, and costs can be reduced.
本発明を実施するための形態（実施形態）につき、詳細に説明する。以下の実施形態に記載した内容により本発明が限定されるものではない。また、以下に記載した構成要素には、当業者が容易に想定できるもの、実質的に同一のものが含まれる。さらに、以下に記載した構成は適宜組み合わせることが可能である。また、本発明の要旨を逸脱しない範囲で構成の種々の省略、置換または変更を行うことができる。 A mode (embodiment) for carrying out the present invention will be described in detail. The present invention is not limited to the contents described in the following embodiments. Further, the constituent elements described below include those that can be easily assumed by those skilled in the art and those that are substantially the same. Furthermore, the configurations described below can be combined as appropriate. Further, various omissions, substitutions, or changes in the configuration can be made without departing from the gist of the present invention.
実施形態の工業油組成物は、基油として、トリメチロールプロパンエステル油および１００℃における動粘度（ＪＩＳ Ｋ ２２８３）が５ｃＳｔ以上であるパラフィン系炭化水素油から選ばれる少なくとも１種を含む。実施形態の工業油組成物は、上記特定の基油を含むため、他の鉱油または合成油を含む工業油組成物とも混ざり合う。したがって、これら他の工業油組成物と一緒に廃棄することができ、取扱い性に優れる。さらに、基油として縮合リン酸エステルを含まないため、コストを抑えられ、環境への負担も低減できる利点がある。 The industrial oil composition of the embodiment contains at least one base oil selected from trimethylolpropane ester oil and paraffinic hydrocarbon oil having a kinematic viscosity (JIS K 2283) of 5 cSt or more at 100°C. Since the industrial oil composition of the embodiment contains the specific base oil, it also mixes with industrial oil compositions containing other mineral oils or synthetic oils. Therefore, it can be disposed of together with these other industrial oil compositions, and is easy to handle. Furthermore, since it does not contain condensed phosphate ester as a base oil, it has the advantage of being able to reduce costs and the burden on the environment.
ところで、摩擦接合ユニットを搭載した自動旋盤装置では、自動旋盤装置の装置自体の潤滑のための潤滑油組成物と、切削加工のための切削加工油組成物とが使用される。そして、上記自動旋盤装置では、摩擦接合時には金属を溶融するほどの高温になり、火花が飛び散る場合もある。 By the way, in an automatic lathe equipped with a friction welding unit, a lubricating oil composition for lubricating the automatic lathe itself and a cutting oil composition for cutting are used. In the automatic lathe device, the temperature becomes high enough to melt metal during friction welding, and sparks may fly.
上記自動旋盤装置において、実施形態の工業油組成物を潤滑油組成物として用いる場合（後述する実施形態１）、装置の使用に伴って、通常、上記工業油組成物が装置表面等にしみ出し得る。そのような状況で摩擦接合を行っても、実施形態の工業油組成物は、上記特定の基油を含むため、しみ出している上記工業油組成物への引火、火災の懸念が低減できる。また、上記自動旋盤装置において、実施形態の工業油組成物を切削加工油組成物として用いる場合（後述する実施形態２）、切削加工に伴って、通常、上記工業油組成物が装置周辺にも付着する。そのような状況で摩擦接合を行っても、実施形態の工業油組成物は、上記特定の基油を含むため、装置周辺に付着している上記工業油組成物への引火、火災の懸念が低減できる。 When the industrial oil composition of the embodiment is used as a lubricating oil composition in the automatic lathe device described above (Embodiment 1 described below), the industrial oil composition usually seeps out onto the surface of the device as the device is used. obtain. Even if friction bonding is performed in such a situation, since the industrial oil composition of the embodiment contains the above-mentioned specific base oil, concerns about ignition of the seeping industrial oil composition and fire can be reduced. In addition, when the industrial oil composition of the embodiment is used as a cutting oil composition in the automatic lathe apparatus (Embodiment 2 described later), the industrial oil composition is usually applied around the apparatus during the cutting process. adhere to. Even if friction bonding is performed in such a situation, since the industrial oil composition of the embodiment contains the above-mentioned specific base oil, there is a concern that the above-mentioned industrial oil composition adhering to the vicinity of the device may catch fire. Can be reduced.
また、摩擦接合ユニットを搭載した自動旋盤装置では、潤滑油組成物として、難燃性を有する、縮合リン酸エステルを含む従来の工業油組成物を用いることも可能である。ここで、環境を考慮して、切削加工油組成物として水溶性組成物が使用されていると、装置の使用に伴って、上記従来の工業油組成物と混ざり合って、縮合リン酸エステルが加水分解する問題が生じ得る。一方、潤滑油組成物として実施形態の工業油組成物を用いる場合は、基油にパラフィン系炭化水素油が含まれていれば、上記加水分解の問題が起こらない利点がある。なお、上記加水分解を好適に抑える観点から、基油１００質量％において、パラフィン系炭化水素油が７０質量％以上１００質量％以下の量で、トリメチロールプロパンエステル油が０質量％以上３０質量％以下の量で含まれていることが好ましい。さらに、基油としてパラフィン系炭化水素油のみを用いることがより好ましい。 Further, in an automatic lathe equipped with a friction bonding unit, it is also possible to use a conventional industrial oil composition containing a condensed phosphate ester and having flame retardancy as a lubricating oil composition. In consideration of the environment, if a water-soluble composition is used as the cutting oil composition, as the equipment is used, it will mix with the conventional industrial oil composition and produce condensed phosphate esters. Hydrolysis problems may arise. On the other hand, when using the industrial oil composition of the embodiment as a lubricating oil composition, there is an advantage that the above-mentioned hydrolysis problem does not occur if the base oil contains a paraffinic hydrocarbon oil. In addition, from the viewpoint of suppressing the above-mentioned hydrolysis, in 100% by mass of the base oil, paraffinic hydrocarbon oil is in an amount of 70% by mass or more and 100% by mass or less, and trimethylolpropane ester oil is in an amount of 0% by mass or more and 30% by mass. It is preferable that it is contained in the following amounts. Furthermore, it is more preferable to use only paraffinic hydrocarbon oil as the base oil.
また、摩擦接合ユニットを搭載した自動旋盤装置では、切削加工油組成物として、難燃性を有する、縮合リン酸エステルを含む従来の工業油組成物を用いることも可能である。ここで、潤滑油組成物として鉱油を含む組成物が使用されていると、装置の使用に伴って、しみ出してきた潤滑油組成物と上記従来の工業油組成物とが混ざり合えず、上記従来の工業油組成物が表面被膜を形成する。上記従来の工業油組成物は、難燃性を有しているが、表面被膜となっていると、摩擦接合時の引火を防ぎきれない懸念がある。一方、切削加工油組成物として実施形態の工業油組成物を用いる場合は、上記基油を含むため、しみ出してきた鉱油を含む潤滑油組成物と混ざり合うことができる。このため、摩擦接合時の引火の懸念が好適に低減できる。 Furthermore, in an automatic lathe equipped with a friction bonding unit, it is also possible to use a conventional industrial oil composition containing a condensed phosphate ester and having flame retardancy as the cutting oil composition. Here, if a composition containing mineral oil is used as the lubricating oil composition, the lubricating oil composition that has seeped out and the above conventional industrial oil composition cannot mix with the use of the equipment, and the above-mentioned conventional industrial oil composition cannot mix. Conventional industrial oil compositions form surface coatings. The conventional industrial oil compositions described above have flame retardancy, but if they form a surface film, there is a concern that they will not be able to prevent ignition during friction welding. On the other hand, when the industrial oil composition of the embodiment is used as the cutting oil composition, since it contains the above-mentioned base oil, it can mix with the lubricating oil composition containing seeped mineral oil. Therefore, concerns about ignition during friction welding can be suitably reduced.
＜実施形態１の工業油組成物＞
実施形態１の工業油組成物は、機械潤滑に好適に用いられる。実施形態１の工業油組成物は、基油と、酸化防止剤と、ミスト防止剤と、油性剤と、金属不活性剤とを含む。
<Industrial oil composition of Embodiment 1>
The industrial oil composition of Embodiment 1 is suitably used for machine lubrication. The industrial oil composition of Embodiment 1 includes a base oil, an antioxidant, a mist inhibitor, an oily agent, and a metal deactivator.
実施形態１の工業油組成物は、基油として、トリメチロールプロパンエステル油および１００℃における動粘度（ＪＩＳ Ｋ ２２８３）が５ｃＳｔ以上であるパラフィン系炭化水素油から選ばれる少なくとも１種を含む。すなわち、基油として、トリメチロールプロパンエステル油およびパラフィン系炭化水素油のいずれか一方を含んでいてもよく、トリメチロールプロパンエステル油およびパラフィン系炭化水素油の両方を含んでいてもよい。実施形態１の工業油組成物は、このような基油を含むため、上述のように、取扱い性に優れ、コストを抑えられる利点がある。また、基油として、トリメチロールプロパンエステル油を用いると、添加剤の選択の幅が広がる利点がある。一方、基油として、パラフィン系炭化水素油を用いると、機械を構成する金属を溶解し難い利点がある。 The industrial oil composition of Embodiment 1 contains, as a base oil, at least one selected from trimethylolpropane ester oil and paraffinic hydrocarbon oil having a kinematic viscosity (JIS K 2283) at 100° C. of 5 cSt or more. That is, the base oil may contain either one of trimethylolpropane ester oil or paraffinic hydrocarbon oil, or may contain both trimethylolpropane ester oil and paraffinic hydrocarbon oil. Since the industrial oil composition of Embodiment 1 contains such a base oil, it has the advantages of excellent handling properties and reduced costs, as described above. Furthermore, the use of trimethylolpropane ester oil as the base oil has the advantage of widening the range of additives to choose from. On the other hand, when paraffinic hydrocarbon oil is used as the base oil, it has the advantage that it does not easily dissolve the metals that make up the machine.
上記基油は、下記の要件（１）、（２）を満たすことができる。
（１）２５０℃に加熱した基油に、火炎を接触させた際に、燃焼を継続しない。
（２）２５０℃に加熱した基油に、７００℃に加熱した金属棒を浸漬させた際に、引火しない。

The above base oil can satisfy the following requirements (1) and (2).
(1) When a flame is brought into contact with base oil heated to 250°C, combustion does not continue.
(2) When a metal rod heated to 700°C is immersed in base oil heated to 250°C, it will not catch fire.

また、上記基油に、後述する添加剤を後述する好ましい量で加えた工業油組成物も、通常、上記要件（１）、（２）を満たす。このような工業油組成物は、準難燃性の工業油組成物ということができ、安定して機械を潤滑可能である。 Further, an industrial oil composition obtained by adding the below-mentioned additives in the below-mentioned preferred amounts to the above-mentioned base oil also usually satisfies the above-mentioned requirements (1) and (2). Such an industrial oil composition can be called a semi-flame-retardant industrial oil composition, and can stably lubricate machines.

The trimethylolpropane ester constituting the trimethylolpropane ester oil may be a full ester or a partial ester. Trimethylolpropane ester is specifically an ester of trimethylolpropane and a straight chain or branched fatty acid having 4 to 18 carbon atoms. Trimethylolpropane esters may be used alone or in combination of two or more. Examples of trimethylolpropane esters include trimethylolpropane valerate heptanoate mixed triester, trimethylolpropane linolenic acid monoester, trimethylolpropane linolenic acid diester, trimethylolpropane linolenic acid triester, and trimethylolpropane stearate monoester. , trimethylolpropane stearate diester, trimethylolpropane stearate triester, trimethylolpropane oleate monoester, trimethylolpropane oleate diester, trimethylolpropane oleate triester, trimethylolpropane isostearate monoester, trimethylolpropane Examples include isostearic acid diester and trimethylolpropane isostearic acid triester. Among these, trimethylolpropane oleate triester (trimethylolpropane trioleate) is preferably used because it has a high kinematic viscosity at 100° C. but has good ability to spread to the cutting edge.

Specifically, 1-decene trimer, 1-undecene trimer, 1-dodecene trimer, 1-tridecene trimer, 1-tetradecene trimer, 1-hexene and 1 - Examples include copolymers with pentene. Further, the paraffinic hydrocarbon oil preferably has a kinematic viscosity at 100° C. of 5 cSt or more and 15 cSt or less. More specifically, poly(1-decene) (PAO5, kinematic viscosity at 100° C.: 5 cSt) is preferably used because of its low evaporation rate. In addition, poly(1-decene) (PAO6, kinematic viscosity at 100° C.: 6 cSt) and poly(1-decene) (PAO19, kinematic viscosity at 100° C.: 10 cSt) are also preferably used.
実施形態１の工業油組成物は、酸化防止剤として、中性亜リン酸エステル誘導体および２，６-ジ－ｔ－ブチルフェノール誘導体を含む。酸化防止剤として上記２種類を組み合わせて用いるため、工業油組成物の使用時に、酸化防止剤の分子が破壊され難くなり、酸化防止剤の消費を抑制できる。中性亜リン酸エステル誘導体および２，６-ジ－ｔ－ブチルフェノール誘導体をそれぞれ単独で用いるよりも、酸化防止剤の消費を抑制できる。したがって、工業油組成物の酸化防止能を長期に渡り持続できる。すなわち、実施形態１の工業油組成物は酸化安定性に優れ、粘度変化も抑制され、長期間使用可能となる。高温で使用する工業油組成物は、酸化防止機能を有することが重要となる。上記２種類の酸化防止剤の組み合わせによれば、工業油組成物を高温で使用する際にも、酸化防止機能を長期に渡って持続できる。 The industrial oil composition of Embodiment 1 includes a neutral phosphite derivative and a 2,6-di-t-butylphenol derivative as antioxidants. Since the above two types of antioxidants are used in combination, the molecules of the antioxidant are less likely to be destroyed when the industrial oil composition is used, and consumption of the antioxidant can be suppressed. Consumption of antioxidant can be suppressed more than using each of the neutral phosphite derivative and the 2,6-di-t-butylphenol derivative alone. Therefore, the antioxidant ability of the industrial oil composition can be maintained for a long period of time. That is, the industrial oil composition of Embodiment 1 has excellent oxidation stability, suppresses viscosity change, and can be used for a long period of time. It is important for industrial oil compositions used at high temperatures to have an antioxidant function. According to the combination of the above two types of antioxidants, the antioxidant function can be maintained for a long period of time even when the industrial oil composition is used at high temperatures.
中性亜リン酸エステル誘導体は、下記式（Ｂ）で表される。中性亜リン酸エステル誘導体は、１種単独で用いても、２種以上を併用してもよい。中性亜リン酸エステル誘導体は、２量体であるため、蒸発しにくく、効率よく酸化防止性能を発揮できる。 The neutral phosphite derivative is represented by the following formula (B). The neutral phosphite derivatives may be used alone or in combination of two or more. Since the neutral phosphite derivative is a dimer, it is difficult to evaporate and can efficiently exhibit antioxidant performance.
式（Ｂ）中、Ｒb21～Ｒb24は、それぞれ独立に、炭素原子数１０～１６の脂肪族炭化水素基を表す。 In formula (B), R b21 to R b24 each independently represent an aliphatic hydrocarbon group having 10 to 16 carbon atoms.
炭素原子数１０～１６の脂肪族炭化水素基は、直鎖、分枝または環状の脂肪族炭化水素基であってもよく、飽和または不飽和の脂肪族炭化水素基であってもよい。炭素原子数１０～１６の脂肪族炭化水素基としては、具体的にはデシル基、ウンデシル基、ドデシル基、トリデシル基、テトラデシル基、ペンタデシル基、ヘキサデシル基（セチル基）などの直鎖状のアルキル基が好適に用いられる。 The aliphatic hydrocarbon group having 10 to 16 carbon atoms may be a linear, branched or cyclic aliphatic hydrocarbon group, or may be a saturated or unsaturated aliphatic hydrocarbon group.

中性亜リン酸エステルは、Ｒb25～Ｒb28に特定の置換基を有しているため、酸化防止性能に加えて、耐摩耗性にも優れる。これは、Ｒb25～Ｒb28に特定の置換基を有していると、摺動部に付着させた工業油組成物の膜がより強固になるためであると考えられる。 Since the neutral phosphite has specific substituents on R b25 to R b28 , it has excellent anti-oxidation properties and excellent wear resistance. This is thought to be because when R b25 to R b28 have specific substituents, the film of the industrial oil composition attached to the sliding part becomes stronger.
特に、Ｒb25およびＲb27が炭素原子数１～６、好ましくは１～３の直鎖状のアルキル基であり、Ｒb26およびＲb28が炭素原子数３～６、好ましくは３～４の分枝状のアルキル基であると、耐摩耗性の改善の効果がより高まる。 In particular, R b25 and R b27 are linear alkyl groups having 1 to 6 carbon atoms, preferably 1 to 3 carbon atoms, and R b26 and R b28 are linear alkyl groups having 3 to 6 carbon atoms, preferably 3 to 4 carbon atoms. A branched alkyl group is more effective in improving wear resistance.

ただし、Ｒb291およびＲb292の炭素原子数の合計は、１～５である。したがって、たとえばＲb291が水素原子のときは、Ｒb292は炭素原子数１～５の直鎖もしくは分枝状のアルキル基であり、Ｒb291がメチル基のときは、Ｒb292は炭素原子数１～４の直鎖もしくは分枝状のアルキル基であり、Ｒb291がエチル基のときは、Ｒb292は炭素原子数２～３の直鎖もしくは分枝状のアルキル基である。 However, the total number of carbon atoms of R b291 and R b292 is 1 to 5. Therefore, for example, when R b291 is a hydrogen atom, R b292 is a straight chain or branched alkyl group having 1 to 5 carbon atoms, and when R b291 is a methyl group, R b292 is a carbon atom number 1. -4 straight chain or branched alkyl group, and when R b291 is an ethyl group, R b292 is a straight chain or branched alkyl group having 2 to 3 carbon atoms.
工業油組成物の膜がより強固になるため、Ｒb291が水素原子であり、Ｒb292が炭素原子数１～５の直鎖もしくは分枝状のアルキル基であることがより好ましい。 Since the film of the industrial oil composition becomes stronger, it is more preferable that R b291 is a hydrogen atom and R b292 is a straight chain or branched alkyl group having 1 to 5 carbon atoms.

式（Ｃ）中、Ｒc1は、炭素原子数１～１２の直鎖もしくは分枝状のアルキル基である。炭素原子数１～１２の直鎖もしくは分枝状のアルキル基としては、メチル基、エチル基、ｎ－プロピル基、イソプロピル基、ｎ－ブチル基、ｓｅｃ－ブチル基、ｔ－ブチル基、イソブチル基、ｎ－ペンチル基、イソペンチル基、ｔ－ペンチル基、ネオペンチル基、ヘキシル基、ヘプチル基、イソヘプチル基、ｎ－オクチル基、イソオクチル基、２－エチルヘキシル基、ノニル基、デシル基が挙げられる。上記アルキル基であると、２，６-ジ－ｔ－ブチルフェノール誘導体の相溶性が向上する。 In formula (C), R c1 is a straight or branched alkyl group having 1 to 12 carbon atoms. Examples of linear or branched alkyl groups having 1 to 12 carbon atoms include methyl group, ethyl group, n-propyl group, isopropyl group, n-butyl group, sec-butyl group, t-butyl group, and isobutyl group. , n-pentyl group, isopentyl group, t-pentyl group, neopentyl group, hexyl group, heptyl group, isoheptyl group, n-octyl group, isooctyl group, 2-ethylhexyl group, nonyl group, and decyl group.

Use of hindered amine compounds can further improve the antioxidant function of industrial oil compositions. Further, when the industrial oil composition is used at high temperatures, the antioxidant function can be further improved. The details of the antioxidant are the same as those described in Embodiment 1, including the preferred range, amount, reason, etc.
実施形態２の工業油組成物は、ミスト防止剤として、炭化水素系高分子化合物を含む。炭化水素系高分子化合物を用いると、高温での工業油組成物の使用時に、ミストの発生を好適に抑えられる。ミスト防止剤の詳細については、好ましい範囲、量、理由なども含め、実施形態１で説明したものと同様である。 The industrial oil composition of Embodiment 2 contains a hydrocarbon-based polymer compound as a mist inhibitor. When a hydrocarbon-based polymer compound is used, generation of mist can be suitably suppressed when an industrial oil composition is used at high temperatures. The details of the mist inhibitor are the same as those described in Embodiment 1, including the preferred range, amount, reason, etc.
実施形態２の工業油組成物は、極圧剤として、硫黄化合物を含む。具体的には活性硫黄化合物を含む。実施形態２の工業油組成物に活性硫黄化合物が含まれていると、高温で使用する際にも、加工性が向上できる。また、実施形態２の工業油組成物は、金属不活性剤として、チアジアゾール誘導体を含む。実施形態２の工業油組成物にチアジアゾール誘導体が含まれていると、高温で使用する際にも、金属表面が保護でき、腐食を防止できる。また、銅系金属の加工も可能となる。実施形態２の工業油組成物においては、上記特定の極圧剤および金属不活性剤を組み合わせているため、より長期に渡って金属を加工できる。 The industrial oil composition of Embodiment 2 contains a sulfur compound as an extreme pressure agent. Specifically, it contains active sulfur compounds. When the industrial oil composition of Embodiment 2 contains an active sulfur compound, processability can be improved even when used at high temperatures. Moreover, the industrial oil composition of Embodiment 2 contains a thiadiazole derivative as a metal deactivator. When the industrial oil composition of Embodiment 2 contains a thiadiazole derivative, the metal surface can be protected and corrosion can be prevented even when used at high temperatures. It also becomes possible to process copper-based metals. In the industrial oil composition of Embodiment 2, since the specific extreme pressure agent and metal deactivator are combined, metals can be processed for a longer period of time.
活性硫黄化合物は、分子内に活性硫黄を含有する化合物であればよい。ここで、活性硫黄化合物とは、たとえば、硫黄原子を含有し金属原子およびリン原子を含有しない化合物のうち、硫黄含量が１質量％になるように精製鉱油で希釈したものについて、ＪＩＳ Ｋ２５１３（石油製品－銅板腐食試験方法；試験管法、１００℃で１時間加熱）に準じて測定した銅板腐食が２～４であるものをいう。なお、一方、硫黄原子を含有し金属原子およびリン原子を含有しない化合物のうち、上記の試験法で、銅板腐食が１である化合物を不活性硫黄化合物という。活性硫黄化合物としては、ポリサルファイド、硫化油脂、粉末硫黄、硫化鉱油、硫化エステル、硫化オレフィンが挙げられる。これらのうちで、硫化オレフィンが好適に用いられる。活性硫黄化合物は、１種単独で用いても、２種以上を併用してもよい。これらの活性硫黄化合物と、原料や硫黄含量が近似していても、製造条件等により、不活性硫黄化合物である場合がある。 The active sulfur compound may be any compound containing active sulfur in its molecule. Here, the active sulfur compound refers to, for example, a compound containing a sulfur atom but no metal atom or phosphorus atom, which is diluted with refined mineral oil so that the sulfur content is 1% by mass, according to JIS K2513 (Petroleum Product - Copper plate corrosion test method: test tube method, heating at 100°C for 1 hour). On the other hand, among compounds containing a sulfur atom but not containing a metal atom or a phosphorus atom, a compound whose copper plate corrosion rate is 1 in the above test method is referred to as an inert sulfur compound. Active sulfur compounds include polysulfides, sulfurized oils and fats, powdered sulfur, sulfurized mineral oils, sulfurized esters, and sulfurized olefins. Among these, sulfurized olefins are preferably used. The active sulfur compounds may be used alone or in combination of two or more. Even if the raw materials and sulfur content are similar to these active sulfur compounds, they may be inactive sulfur compounds depending on manufacturing conditions and the like.
チアジアゾール誘導体は、好ましくは２，５－ビス（アルキルジチオ）－１，３，４－チアジアゾールであり、下記式（Ｆ）で表される。このようなチアジアゾール誘導体が含まれていると、高温で使用する際にも、腐食をより防止できる。 The thiadiazole derivative is preferably 2,5-bis(alkyldithio)-1,3,4-thiadiazole, and is represented by the following formula (F). When such a thiadiazole derivative is contained, corrosion can be further prevented even when used at high temperatures.
上記式（Ｆ）中、Ｒf1およびＲf2は、それぞれ独立に、炭素原子数１～２０のアルキル基を示し、ａおよびｂは、それぞれ独立に、１、２または３を表す。チアジアゾール誘導体は、１種単独で用いても、２種以上を併用してもよい。 In the above formula (F), R f1 and R f2 each independently represent an alkyl group having 1 to 20 carbon atoms, and a and b each independently represent 1, 2 or 3. Thiadiazole derivatives may be used alone or in combination of two or more.
実施形態２の工業油組成物において、基油１００質量部に対して、硫黄化合物は、０．０１質量部以上５質量部以下の量で含まれることが好ましい。また、実施形態２の工業油組成物において、基油１００質量部に対して、チアジアゾール誘導体は、０．０１質量部以上５質量部以下の量で含まれることが好ましい。 In the industrial oil composition of embodiment 2, the sulfur compound is preferably contained in an amount of 0.01 parts by mass or more and 5 parts by mass or less per 100 parts by mass of the base oil. Also, in the industrial oil composition of embodiment 2, the thiadiazole derivative is preferably contained in an amount of 0.01 parts by mass or more and 5 parts by mass or less per 100 parts by mass of the base oil.
実施形態２の工業油組成物は、通常、銅板腐食試験（ＪＩＳ Ｋ ２５１３）において、変色番号が２以内の結果が得られる。なお、銅板腐食試験では、具体的には、実施形態２の工業油組成物に、よく磨いた銅板を浸し、１００℃で３時間保った後、銅板を取り出し洗浄して、銅板腐食標準と比較する。 The industrial oil composition of embodiment 2 usually achieves a discoloration number of 2 or less in the copper plate corrosion test (JIS K 2513). Specifically, in the copper plate corrosion test, a well-polished copper plate is immersed in the industrial oil composition of embodiment 2 and kept at 100°C for 3 hours, after which the copper plate is removed, washed, and compared with the copper plate corrosion standard.
また、実施形態２の工業油組成物は、通常、耐圧性（ＡＳＴＭ Ｄ ２７８３）が１６０ｋｇｆ以上であり、摩擦係数（振り子式摩擦試験）が０．１５以下である。 Further, the industrial oil composition of Embodiment 2 usually has a pressure resistance (ASTM D 2783) of 160 kgf or more and a friction coefficient (pendulum friction test) of 0.15 or less.
実施形態２の工業油組成物は、上述した成分を適宜混合して調製することができる。 The industrial oil composition of Embodiment 2 can be prepared by appropriately mixing the above-mentioned components.
実施形態２の工業油組成物によれば、上述のように、室温のみならず高温においても高い安定性を発揮できるため、長期に渡って金属を加工できる。さらに、上述のように、たとえば摩擦接合ユニットを搭載した自動旋盤装置にも好ましく用いられる。具体的には、切削加工に用いる工業油組成物は、通常、装置周辺にも付着する。切削加工に続いて摩擦接合を行うと、金属を溶融するほどの高温になったり、火花が飛び散ったりすることがある。そのような場合にも、工業油組成物への引火による火災の懸念が低減できる。 According to the industrial oil composition of Embodiment 2, as described above, it can exhibit high stability not only at room temperature but also at high temperatures, so that metals can be processed over a long period of time. Furthermore, as mentioned above, it is preferably used, for example, in an automatic lathe device equipped with a friction welding unit. Specifically, industrial oil compositions used for cutting usually adhere to the periphery of the equipment. When friction welding is performed after cutting, the temperature can be high enough to melt the metal, and sparks can fly. Even in such a case, concerns about fire due to ignition of the industrial oil composition can be reduced.
ところで、自動旋盤装置（具体的には摩擦接合ユニットを搭載した自動旋盤装置）においては、実施形態１の工業油組成物および実施形態２の工業油組成物を併用することが好ましい。すなわち、実施形態１の工業油組成物により、機械を潤滑し、実施形態２の工業油組成物により、切削加工を行うことが好ましい。これにより、実施形態１の工業油組成物および実施形態２の工業油組成物が、装置の稼働時に分離せずに混和する利点がある。 By the way, in an automatic lathe device (specifically, an automatic lathe device equipped with a friction bonding unit), it is preferable to use the industrial oil composition of Embodiment 1 and the industrial oil composition of Embodiment 2 together. That is, it is preferable that the industrial oil composition of Embodiment 1 lubricates the machine and the industrial oil composition of Embodiment 2 performs cutting. This has the advantage that the industrial oil composition of Embodiment 1 and the industrial oil composition of Embodiment 2 are mixed without being separated during operation of the apparatus.
＜その他の実施形態の工業油組成物＞ <Industrial oil compositions of other embodiments>
その他の実施形態の工業油組成物として、実施形態１、２の工業油組成物に、さらに、その他の添加剤が含まれていてもよい。その他の添加剤としては、塩素化パラフィンが挙げられる。その他の添加剤は、工業油組成物について長期の使用等の効果を妨げない範囲で含まれていることが好ましい。 As industrial oil compositions of other embodiments, the industrial oil compositions of Embodiments 1 and 2 may further contain other additives. Other additives include chlorinated paraffins. It is preferable that other additives are included in the industrial oil composition to the extent that they do not impede the effects of long-term use.
また、その他の実施形態の工業油組成物としては、実施形態１の工業油組成物に対して、ミスト防止剤、油性剤および金属不活性剤の少なくとも１種を含まない組成物であってもよい。 In addition, the industrial oil composition of other embodiments may be a composition that does not contain at least one of a mist preventive agent, an oily agent, and a metal deactivator compared to the industrial oil composition of Embodiment 1. good.
あるいは、実施形態２の工業油組成物に対して、ミスト防止剤および金属不活性剤の少なくとも１種を含まない組成物であってもよい。実施形態２の工業油組成物において、上述した金属不活性剤を含まない場合は、銅系金属以外、たとえば鉄を含む金属の加工に好適に用いることができる。また、実施形態２の工業油組成物において、上述した金属不活性剤を含まない場合は、極圧剤として、活性硫黄化合物の代わりに不活性硫黄化合物を用いてもよい。 Alternatively, the industrial oil composition of Embodiment 2 may be a composition that does not contain at least one of a mist inhibitor and a metal deactivator. When the industrial oil composition of Embodiment 2 does not contain the metal deactivator described above, it can be suitably used for processing metals other than copper-based metals, such as metals containing iron. Moreover, in the industrial oil composition of Embodiment 2, when the above-mentioned metal deactivator is not included, an inert sulfur compound may be used as the extreme pressure agent instead of the active sulfur compound.
いずれの工業油組成物も、酸化防止機能に優れ、常温のみならず高温で長期にわたって使用可能である。 All industrial oil compositions have excellent antioxidant properties and can be used not only at room temperature but also at high temperatures for a long period of time.

[Evaluation method and evaluation results]
[Flammability]
Specifically, the following evaluation tests (1) and (2) were conducted as evaluation tests for flammability.
(1) The evaluation target was heated to 250°C and brought into contact with the flame of a utility lighter for 1 to 2 seconds. At this time, it was investigated whether the subject to be evaluated would catch fire. The test was judged as passing if it did not catch fire, and failing if it caught fire.
(2) Heat a metal rod (diameter 4.5 mm, length 86 mm) in advance for 30 seconds at 1400 to 1600°C with a torch (product name: Strong wind-resistant burner power torch RZ-840AK, manufactured by Shinfuji Burner Co., Ltd.). I kept it. As a result, the metal rod was heated to 700°C or higher. The evaluation object was heated to 250° C., and the metal rod that had been previously heated as described above was immersed therein. At this time, it was investigated whether the subject to be evaluated would catch fire. The test was judged as passing if it did not catch fire, and failing if it caught fire.

[Antioxidant function]
First, two cylindrical disks (diameter 30 mm, thickness 5 mm, manufactured by SUJ2) were prepared. The industrial oil composition obtained in the example was applied to the bottom surface of one disk, and the bottom surface of the other disk was superimposed on the applied industrial oil composition. Two stacked disks were immersed in the industrial oil composition obtained in the example heated to 80° C. in a container with the bottom surface perpendicular to the ground. Next, while pressing the other disk against the one disk under a pressure of 150 kg, the one disk was rotated at 1000 rpm for 3 or 6 hours. In this way, industrial oil compositions were made that were subjected to a 3 or 6 hour thermal history.
Next, a pendulum type friction test was performed on the industrial oil composition that had undergone a thermal history of 3 hours or 6 hours to determine the friction coefficient. Specifically, the industrial oil composition present between the disks after rotation for 3 or 6 hours and the industrial oil composition in the container were combined and used in a pendulum friction test. Furthermore, the coefficient of friction was similarly determined for the industrial oil composition obtained in the example in the as-produced state (state without thermal history).
Table 5 shows the results.

さらに、チタン部品の製造後、摩擦接合ユニットを用いて、チタン部材の摩擦接合を行った。この際、火花が散っても自動旋盤装置やその周囲に付着している工業油組成物に引火することなく、安全に行うことができた。
なお、実施例１－１で得られた工業油組成物の代わりに、実施例１－２～１－１０、２－１～２－１２で得られた工業油組成物を使用した場合、また、実施例３－１で得られた工業油組成物の代わりに、実施例３－２、４－１～４－３で得られた工業油組成物を使用した場合も、上記と同様の結果が得られた。
[Lubricity/workability]
In a prototype machine equipped with a friction bonding unit in an automatic lathe (product name: Cincom L32, manufactured by Citizen Machinery Co., Ltd.), the industrial oil composition obtained in Example 1-1 was applied to the sliding part of the automatic lathe. Using the industrial oil composition obtained in Example 3-1 during cutting, a titanium member was cut to produce 100 titanium parts. Furthermore, when the sliding parts of the automatic lathe were observed after manufacturing the titanium parts, no wear was observed. It was found that the industrial oil composition obtained in Example 3-1 could appropriately cut titanium parts, and that the industrial oil composition obtained in Example 1-1 could appropriately lubricate sliding parts. .
Furthermore, after manufacturing the titanium parts, friction welding of the titanium members was performed using a friction welding unit. At this time, even if sparks were scattered, the process could be carried out safely without igniting the automatic lathe equipment or the industrial oil composition attached to its surroundings.
In addition, when the industrial oil composition obtained in Examples 1-2 to 1-10 and 2-1 to 2-12 is used instead of the industrial oil composition obtained in Example 1-1, , the same results as above were obtained when the industrial oil compositions obtained in Examples 3-2 and 4-1 to 4-3 were used instead of the industrial oil composition obtained in Example 3-1. was gotten.
