Abstract
Description
回転式圧縮機は、従来の往復式と比較して、省資源や騒音、振動の対策および効率等の観点から、幅広く使用されている。一方、回転式圧縮機の潤滑条件は、潤滑油が高温高圧の空気やガスと接触することなど、往復式の場合より過酷であるため、熱安定性および酸化安定性の高い圧縮機油が望まれている。
一方、潤滑油に汎用的に用いられているフェノール系酸化防止剤(ジ-t-ブチル-p-クレゾール)は揮発し易く、また、変色度合いも大きいため、耐久性、ならびに油の変色抑制の観点から十分ではなかった。さらに、フェノール系酸化防止剤やアミン系酸化防止剤は、それ自体では十分な摩擦特性(耐焼付性、耐摩耗性)を有しておらず、潤滑性向上のためには、耐熱性や酸化安定性に乏しい硫黄/リンなどを含む摩擦調整剤を併用せざるを得なかった。
しかし、このジチオリン酸亜鉛は、分子中に金属分(亜鉛)とともに、リン分および硫黄分を多量に含んでいることから、ジチオリン酸亜鉛の分解物は硫酸や燐酸を発生する。そのため、ジチオリン酸亜鉛は、エンジン油中の塩基性化合物を消耗して潤滑油の劣化を促進し、更油期間を極端に短くすることがある(この現象は、いわゆる塩基価維持性が不充分であることを意味する)。また、ジチオリン酸亜鉛は高温条件でスラッジ化し、エンジン内部の清浄性を悪化することがあることも問題視されている。
このような状況から、ジチオリン酸亜鉛に変わる内燃機関用潤滑油に使用できる耐摩耗添加剤の出現が望まれている。
したがって、低金属分(すなわち、低硫酸灰分)、低リン分、さらには低硫黄分であっても内燃機関用潤滑油に要求される基本的に性能(耐摩耗性、清浄性、塩基価維持性など)を具備する内燃機関用潤滑油が切望されている。
〔1〕基油に、下記の一般式(1)で示す構造を有するリン化合物を配合してなる潤滑油組成物である。
〔2〕さらに、酸化防止剤、無灰系分散剤、金属系清浄剤、摩擦調整剤、極圧剤、防錆剤、粘度指数向上剤、流動点降下剤、金属不活性化剤、消泡剤、抗乳化剤及び着色剤から選ばれる少なくとも一種の添加剤を配合してなる〔1〕に記載の潤滑油組成物である。
〔3〕前記酸化防止剤が、アミン系酸化防止剤である〔2〕に記載の潤滑油組成物である。
〔4〕リン含有量が組成物基準で0.12質量%以下であり、かつ硫酸灰分が1.2質量%以下である〔1〕~〔3〕のいずれかに記載の潤滑油組成物である。
〔5〕前記基油における環分析による%CAが10以下で、硫黄分が300質量ppm以下であり、粘度指数が80以上である〔1〕~〔4〕のいずれかに記載の潤滑油組成物である。
〔6〕ガス圧縮機用である〔1〕~〔5〕のいずれかに記載の潤滑油組成物である。
〔7〕内燃機関用である〔1〕~〔5〕のいずれかに記載の潤滑油組成物である。
本発明で用いる基油としては、特に制限はなく、従来、潤滑油の基油として使用されている鉱油や合成油の中から任意のものを適宜選択して用いることができる。
上記鉱油としては、例えば、原油を常圧蒸留して得られる常圧残油を減圧蒸留して得られた潤滑油留分を、溶剤脱れき、溶剤抽出、水素化分解、溶剤脱ろう、接触脱ろう、水素化精製等の1つ以上の処理を行って精製した鉱油、あるいはワックス、GTL WAXを異性化することによって製造される鉱油等が挙げられる。
本発明においては、基油として、前記鉱油は一種を単独で用いてもよく、二種以上を組み合わせて用いてもよい。また、前記合成油を一種用いてもよく、二種以上を組み合わせて用いてもよい。更には、鉱油一種以上と合成油一種以上とを組み合わせて用いてもよい。
40℃における動粘度が1~1000mm2/sの範囲にあると圧縮機の自動変速機のギヤ軸受けやクラッチなどの摺動部における摩擦を十分に低減し得るとともに、低温特性も良好となる。また、100℃における動粘度が2~30mm2/sの範囲にあると蒸発損失が少なく、また粘性抵抗による動力損失が抑制され、燃費改善効果が得られる。
ここで、環分析による%CAとは、環分析n-d-M法にて算出した芳香族分の割合(百分率)を示す。また、硫黄分はJIS K 2541に準拠して測定した値である。
%CAが10以下で、硫黄分が300質量ppm以下の基油は、良好な酸化安定性を有し、酸価の上昇やスラッジの生成を抑制しうる潤滑油組成物を提供することができる。より好ましい%CAは3.0以下、さらに好ましくは1.0以下、特に好ましくは0.5以下である。また、より好ましい硫黄分は200質量ppm以下、さらに好ましくは100質量ppm以下であり、特に好ましくは30質量ppm以下である。
さらに、基油の粘度指数は、70以上が好ましく、より好ましくは100以上、さらに好ましくは120以上である。この粘度指数が70以上の基油は、温度の変化による粘度変化が小さい。

<実施例A1~A6、比較例A1~A4>
各実施例および比較例において、それぞれ以下に示す基油および添加剤を用いて表1に示す組成を有する潤滑油組成物(以下、「試料油」ともいう)を調製した。
(1)鉱油:API分類 GI、動粘度(40℃) 29.28mm2/s
(2)鉱油:API分類 GII、動粘度(40℃) 30.98mm2/s

6-[3-(3-t-ブチル-4-ヒドロキシ-5-メチルフェニル)プロポキシ]-2,4,8,10-テトラ-t-ブチルジベンズ[d,f][1,3,2]-ジオキサホスフェピン
(2)酸化防止剤B:ジオクチルジフェニルアミン
(3)酸化防止剤C:オクチルフェニルナフチルアミン

(5)その他:防錆剤(アルケニルコハク酸エステル)、金属不活性化剤(ベンゾトリアゾール)、消泡剤(ジメチルシリコーン)
(潤滑性試験(耐摩耗性試験および耐荷重性試験))
・耐摩耗性試験(シェル摩耗試験):
ASTM D 2783に準拠して、荷重192N、回転数1200rpm、油温80℃、試験時間60分の条件で行った。1/2インチ球3個の摩耗痕径を平均して平均摩耗痕径を算出した。
・耐荷重性試験(シェルEP試験):
ASTM D 2783に準拠して、回転数1800rpm、室温の条件で行った。最大非焼付荷重(LNL)と融着荷重(WL)から荷重摩耗指数(LWI)を求めた。この値が大きいほど耐荷重性が良好である。
JIS K 2540に準拠して行った。具体的には、試料油を150℃で168時間保持した後の動粘度、酸価およびミリポア量を測定した。各項目は、以下のようにして測定した。
・動粘度:JIS K 2283に準拠して測定した。新油に比べてこの値が高くなるほど増粘傾向があると言える。
・酸価:JIS K 2501に準拠して測定した。新油に比べてこの値が高くなるほど酸化劣化が進行しているとわかる。
・ミリポア量:孔径0.8μmのメンブランフィルターを用い、熱安定度試験後の試料油を減圧下にて100mlろ過する。ろ過前後のフィルター質量から、フィルターに捕捉された試料油不溶物の量を測定する。この値が高ければ高いほど試料油不溶分(スラッジ)が多いことがわかる。
JIS K 2514に準拠して行った。具体的には、試料油を165.5℃に保ち、鋼-銅触媒存在の下、1300rpmで強制攪拌し、周りの空気を攪拌により試料油内に取り込みながら96時間保持した。その後、前記した熱安定度試験と同様の方法で試料油の動粘度、酸価およびミリポア量を測定した。ISOTは、試料油を加速的に酸化劣化させる試験であるため、前記した熱安定度試験よりも空気による酸化の影響がより顕著に現れる。
また、実施例A6の試料油は、ガス圧縮機用として一般的な添加剤をさらに配合したものであるが、本発明の主要な構成要素である特定の酸化防止剤の効果が阻害されることもなく、上記した各特性が維持されていることがわかる。
これに対して、比較例A1~A4の試料油では、酸化防止剤として、DBPCやアミン系酸化防止剤のような汎用の酸化防止剤しか配合されておらず、本発明における特定の酸化防止剤が配合されていないので、潤滑性、熱安定性および酸化安定性に劣るとともに、スラッジの発生も顕著である。
