しかしながら、後述するように極圧剤が金属表面に皮膜を形成するような極圧潤滑条件に至るまでに、炭化水素、もしくは潤滑油組成物を構成する他の有機成分が加熱、せん断により極圧潤滑条件以前に炭化してしまい、金属表面に炭化物被膜を形成する可能性がある。
本発明の潤滑油組成物は工業用潤滑油(ギア油、作動油)およびグリース用基油として用いることが可能である。また、上述したように、本発明の潤滑油組成物は剪断安定性、低温粘度特性および耐マイクロピッチング性能に優れるため、風力発電機用潤滑油として特に好適に用いられる。なお、剪断安定性および耐マイクロピッチング性能に優れていると、風力発電機用ギアに用いたときにメンテナンスフリーとすることができる。また、低温粘度特性に優れていることは、風力から電力へのエネルギー変換効率の観点からも好ましい。
(i)90~10質量%の100℃における動粘度が45mm2/s以下であり、1-デセンから導かれる構成単位を60mol%以上含み、かつ酸価が0.1mgKOH/g未満である(共)重合体
(ii)5~85質量%の100℃における動粘度が35mm2/s以上1,500mm2/s以下であり、1-オクテンから導かれる構成単位を90mol%以上含み、かつゲルパーミエーションクロマトグラフィーにより測定された分子量分布が1.8以下である(共)重合体
(iii)5~15質量%の100℃における動粘度が20mm2/s以下である脂肪酸エステル
(ただし、(i)~(iii)の合計を100質量%とする。)
上記潤滑油組成物は、特定の(i)デセン(共)重合体に特定の(ii)オクテン(共)重合体を組み合わせているため、剪断安定性、低温粘度特性および温度粘度特性に優れる。また、ホウ素含有量が特定の範囲にあるため、耐マイクロピッチング性能および低温粘度特性に優れる。
数平均分子量(Mn)および分子量分布(Mw/Mn)は、島津製作所製のGPC(クロマトパックC-R4A)を用い以下のようにして測定した。分離カラムとして、TSKG6000H XL、G4000H XL、G3000H XL、G2000H XLを用い、カラム温度を40℃とし、移動相にはテトラヒドロフラン(和光純薬社製)を用い、展開速度を0.8ml/分とし、試料濃度を0.2質量%とし、試料注入量を20マイクロリットルとし、検出器として示差屈折計を用いた。標準ポリスチレンとしては、東ソー社製のものを用いた。
100℃および40℃での動粘度、並びに粘度指数はJIS K2283に記載の方法により、測定、算出した。
潤滑油組成物の剪断安定性はDIN 52350-6に記載の方法に準拠し、KRL剪断安定性試験機を用いて評価した。配合油を60℃で20hrの間、剪断条件下(1450rpm)におき、試験前後での40℃での動粘度の低下率を評価した。
-30℃粘度は、ASTM D2983に準拠して、ブルックフィールド粘度計により測定した。測定による誤差を考慮し、-30℃粘度は以下の3段階に分類した。
中:80,000超~100,000mPa・s
低:80,000mPa・s以下
-30℃粘度は100,000mPa・s以下であれば、-40℃程度までの極低温下において良好な潤滑性が維持可能であり、優れた省燃費性・エネルギー変換効率を示す。特に80,000mPa・s以下であると極めて優れた省燃費性・エネルギー変換効率を示す。-30℃において100,000mPa・sを超えると、極低温環境下においての省燃費性・エネルギー変換効率は乏しくなる。
駆動技術研究連盟(FVA)により規定されたFVA-54/7マイクロピッチング試験により、不合格負荷段階を測定した。不合格負荷段階が10以上であれば、優れた耐マイクロピッチング性能を示す。
(i)100℃における動粘度が45mm2/s以下であり、1-デセンからなるデセン(共)重合体として、NESTE OIL社製のポリ-α-オレフィン(PAO)、NEXBASE2006(100℃における動粘度、6mm2/s)を用いた。JIS K2501に従い測定した酸価は0.1mgKOH/g未満であった。
(ii)1-オクテンをモノマーとするオクテン(共)重合体は、以下の重合例により製造した。
窒素雰囲気下、200mlの3口フラスコにリチウムシクロペンタジエン5.9g(81.9mmol)を加え、脱水ジエチルエーテル100mlをさらに加えて攪拌した。このスラリー溶液をアイスバスで冷却し、4'-メチルアセトフェノン10.0g(74.5mmol)を滴下した。その後室温で20時間攪拌し、得られた溶液を希塩酸水溶液でクエンチした。ヘキサン50mlを添加し、この有機層を水で洗浄後、無水硫酸マグネシウムで乾燥した。溶媒を留去し、得られた粘性液体をヘキサンでカラムクロマトグラフィー分離し、赤色粘性液体の目的物を得た(収量9.8g、収率72%)。
