本組成物において、下記式(1)で示される構造を有するエーテル系化合物が基油として好ましく挙げられる。
Ra―〔(ORb)n―(B)―(ORc)k〕x―Rd (1)
ここで、式中、Ra、Rdはそれぞれ水素原子、炭素数1から10までのアルキル基、炭素数2から10までのアシル基または結合部2個から6個までを有する炭素数1から10までの炭化水素基、Rb、Rcはそれぞれ炭素数2から4までのアルキレン基、n、kは0から20までの整数であり、xは1から6までの整数である。(B)は、下記式(2)で示されるモノマー単位を3以上含んだ重合部である。
エーテル系化合物としては、次の末端構造を有するもの、すなわち末端が、式(1)においてRaが水素原子、n=0であり、かつ残りの末端が、Rdが水素原子、k=0で表される構造を有するものが合成反応の安定性の点で好ましい。特に、ポリプロピレングリコールとポリエチルビニルエーテルとの共重合体、ポリエチレングリコールとポリエチルビニルエーテルとの共重合体が好ましい。
本発明においては、上述した各基油(鉱油、合成系基油)は単独でも混合して用いてもよいが、いずれの場合でも、好ましい100℃動粘度は1mm2/s以上50mm2/s以下であり、より好ましくは3mm2/s以上50mm2/s以下であり、さらに好ましくは5mm2/s以上30mm2/s以下であり、特に好ましくは5mm2/s以上20mm2/s以下である。
本組成物における基油の粘度指数は、好ましくは60以上であり、より好ましくは80以上であり、さらに好ましくは100以上である。
本添加剤は、冷媒および本組成物が冷凍機(冷凍システム)から漏れた場合に漏洩検出剤として機能する。すなわち、ビフェニル構造やスチルベン構造のような共役系を有する炭化水素化合物は、紫外線を当てることにより蛍光を発するので、漏れ箇所を容易に見つけることができる。しかも、本添加剤を配合してなる潤滑油組成物および冷媒からなる系は熱的にも化学的にも安定である。
上述した炭化水素化合物の好ましい配合量(添加量)は、潤滑油組成物基準で、0.001質量%以上10質量%以下が好ましく、より好ましくは0.001質量%以上1質量%以下、さらに好ましくは0.001質量%以上0.5質量%以下、最も好ましくは0.001質量%以上0.1質量%以下である。配合量がこの下限値よりも少ないと、冷凍機から本組成物が漏出しても蛍光量が少なく、漏洩箇所がわかりにくくなるおそれがある。一方、上限値よりも多く配合しても漏洩検出剤としての効果の向上は特になくむしろ本組成物の安定性を阻害するおそれがある。
CpOqFrRs (A)
(式中、Rは、Cl、Br、Iまたは水素を示し、pは1から6まで、qは0から2まで、rは1から14まで、sは0から13までの整数である。ただし、qが0の場合は、pは2から6までであり、分子中に炭素-炭素不飽和結合を1以上有する。)
この飽和HFCとしては、炭素数1から4までのアルカンのフッ化物が好ましく、特に炭素数1か2のメタンやエタンのフッ化物であるトリフルオロメタン、ジフルオロメタン、1,1-ジフルオロエタン、1,1,1-トリフルオロエタン、1,1,2-トリフルオロエタン、1,1,1,2-テトラフルオロエタン、1,1,2,2-テトラフルオロエタン、1,1,1,2,2-ペンタフルオロエタンが好適である。
また、当該飽和HFCを上述の(A)化合物冷媒と混合して使用する場合は、その配合量は、冷媒全量に基づき、30質量%以下が好ましく、より好ましくは20質量%以下、さらに好ましくは10質量%以下である。
分子式(A)は、分子中の元素の種類と数を示すものであり、式(A)は、炭素原子Cの数pが1から6までである含フッ素有機化合物を表している。炭素数が1から6までの含フッ素有機化合物であれば、冷媒として要求される沸点、凝固点、蒸発潜熱などの物理的、化学的性質を有することができる。
分子式(A)において、Cpで表されるp個の炭素原子の結合形態は、炭素-炭素単結合、炭素-炭素二重結合等の不飽和結合、炭素―酸素二重結合などが含まれる。炭素-炭素の不飽和結合は、安定性の点から、炭素-炭素二重結合であることが好ましく、その数は1以上であるが、1であるものが好ましい。
分子式(A)において、Oqで表されるq個の酸素原子の結合形態は、エーテル基、水酸基またはカルボニル基に由来する酸素であることが好ましい。この酸素原子の数qは、2であってもよく、2個のエーテル基や水酸基等を有する場合も含まれる。Oqにおけるqが0であり分子中に酸素原子を含まない場合は、pは2から6までであって、分子中に炭素-炭素二重結合等の不飽和結合を1以上有する。すなわち、Cpで表されるp個の炭素原子の結合形態の少なくとも1つは、炭素-炭素不飽和結合であることが必要である。
分子式(A)において、Rは、Cl、Br、Iまたは水素を表し、これらのいずれであってもよいが、オゾン層を破壊する恐れが小さいことから、Rは、水素であることが好ましい。
上記のとおり、分子式(A)で表される含フッ素有機化合物としては、不飽和フッ化炭化水素化合物、フッ化エーテル化合物、フッ化アルコール化合物およびフッ化ケトン化合物などが好適なものとして挙げられる。
以下、これらの化合物のうち不飽和フッ化炭化水素化合物について詳細に説明する。
このような不飽和フッ化炭化水素化合物として好ましくは、例えば、炭素数2から6までの直鎖状または分岐状の鎖状オレフィンや炭素数4から6までの環状オレフィンのフッ素化物を挙げることができる。
具体的には、1個から3個までのフッ素原子が導入されたエチレン、1個から5個までのフッ素原子が導入されたプロペン、1個から7個までのフッ素原子が導入されたブテン類、1個から9個までのフッ素原子が導入されたペンテン類、1個から11個までのフッ素原子が導入されたヘキセン類、1個から5個までのフッ素原子が導入されたシクロブテン、1個から7個までのフッ素原子が導入されたシクロペンテン、1個から9個までのフッ素原子が導入されたシクロヘキセンなどが挙げられる。
また、炭素数1か2の飽和フッ化炭化水素冷媒と炭素数3の不飽和フッ化炭化水素冷媒との組み合わせも好適に用いられる。このような組み合わせとしては、例えば前記のHFO1234yfとCH2F2(HFC32)との組み合わせ、HFO1234zeとHFC32との組み合わせ、HFO1234yfとCHF2CH3(HFC152a)との組み合わせ、およびHFO1234zeとHFC152aとの組み合わせなどを挙げることができる。
極圧剤としては、リン酸エステル、酸性リン酸エステル、亜リン酸エステル、酸性亜リン酸エステルおよびこれらのアミン塩などのリン系極圧剤、カルボン酸の金属塩、硫化油脂、硫化脂肪酸、硫化エステル、硫化オレフィン、ジヒドロカルビルポリサルファイド、チオカーバメート類、チオテルペン類、およびジアルキルチオジプロピオネート類などの硫黄系極圧剤を挙げることができる。
上記極圧剤の配合量は、潤滑性および安定性の点から、組成物全量に基づき、0.001質量%以上10質量%以下が好ましい。
上記油性剤の配合量は、組成物全量に基づき、0.01質量%以上10質量%以下が好ましい。
また、その好ましい配合量は、効果およびスラッジ発生の抑制の点から、組成物全量に基づき、0.005質量%以上5質量%以下である。
金属不活性化剤としては、例えばN-[N’,N’-ジアルキル(炭素数3から12までのアルキル基)アミノメチル]トルトリアゾールなどを挙げることができ、前記消泡剤としては、例えばシリコーン油やフッ素化シリコーン油などを挙げることができる。
本組成物を使用する冷凍機では、前記各種冷媒と本組成物の使用量について、冷媒/本組成物の質量比で99/1~10/90、更に95/5~30/70の範囲にあることが好ましい。冷媒の量が上記範囲よりも少ない場合は冷凍能力の低下が見られ、また上記範囲よりも多い場合は潤滑性能が低下し好ましくない。
また、この冷凍システムにおいては、システム内の水分含有量は500質量ppm以下が好ましく、300質量ppm以下がより好ましい。また、残存空気分圧は、13kPa以下が好ましく、10kPa以下さらには5kPa以下がより好ましい。
〔実施例1~10および比較例1~5〕
表1、2に示す配合組成の潤滑油組成物を調製し、以下に示す熱安定性試験により組成物の熱的・化学的安定性を評価した。
内容積200mLのオートクレーブに、組成物/冷媒(30g/30gの比率、組成物中の水分500質量ppm)と、鉄、銅およびアルミニウムからなる金属触媒を充填して封管し(空気25mL)、温度175℃の条件にて168時間保持後、酸価を測定した。なお、酸価は、JIS K2501に規定される「潤滑油中和試験方法」に準拠し、電位差法により測定した。
冷媒としては、HFO1234yf(2,3,3,3-テトラフルオロプロペン)を用いた。
PAG:ポリオキシプロピレングリコールジメチルエーテル、100℃動粘度:9.25mm2/s
PVE:ポリビニルエーテル、100℃動粘度:15.97mm2/s
ECP:ポリビニルエーテル-ポリアルキレングリコール共重合物(モル比1:1)、100℃動粘度:9.56mm2/s
POE:ポリオールエステル、40℃動粘度:68.5mm2/s
漏洩検出剤1:p-ビス(o-メチルスチル)ベンゼン
漏洩検出剤2:2,5,2’’’,5’’’-テトラメチル-p-クオーターフェニル
漏洩検出剤3:2’’,3,3’,3’’’-テトラメチル-1,1’:4’,1’’:4’’,1’’’-クアテルベンゼン
漏洩検出剤4:2-(4-tert-ブチルフェニル)-5-(4-ビフェニリル)-1,3,4-オキサジアゾール
なお、表中のその他添加剤は酸化防止剤、酸捕捉剤、酸素捕捉剤、および極圧剤である。
表1の結果より、添加剤としてビフェニル構造あるいはスチルベン構造を有する炭化水素化合物を配合した潤滑油組成物と冷媒とを混合した系である実施例1~10では、いずれも酸価はほとんど高くなっておらず、熱的・化学的安定性が高いことがわかる。
一方、表2の結果より、実施例で用いた添加剤とは異なる構造を有する添加剤を配合した比較例1~5では、いずれも酸価が高くなっており熱的・化学的安定性が十分でないことがわかる。
以上の結果より、所定の添加剤を配合した本発明の冷凍機用潤滑油組成物は、不安定な構造を有する冷媒を用いた冷凍機に適用しても長期間安定して冷媒の漏れ検出が可能であることが理解される。
