この実施例において他に記載がない限り、%表示は重量%に関する。イオン液体の添加により、残りの基油のパーセント割合は、他に記載がない限り相応して低下する。
グリース組成物の製造のために、基油としてトリメリト/ピロメリト酸エステルからなる混合物77質量%、イオン液体としてのMPBイミド10質量%、増粘剤としてポリ尿素又は二尿素8質量%及び添加物として腐食防止剤、酸化防止剤及び摩耗防止剤5質量%を混合する。このイオン液体は、基油中で前記増粘剤のin situ製造の後で混合され、高圧ホモジナイザー、三本ロール機又は他の適当な方法を用いて均質化する。
L10=73h
L50=222h
β=1.7
で、本発明によるグリース組成物が、転がり軸受用グリースのための騒音試験の要求及びDIN基準を満たすだけでなく、この値を大きく上回る結果を示した。
グリース組成物の製造のために、基油としてのポリ−α−オレフィンからなる混合物79質量%、増粘剤としてのリチウム単純セッケン17質量%、添加物4質量%からなるグリースに、さらにイオン液体としてMPBイミド10〜30質量%を添加する。このイオン液体は、冷間で、リチウムセッケングリースのin situ製造の後にベース油に添加し、撹拌し、均質化にロール処理した。
この実施例中で、合成炭化水素、合成エステル、芳香族ジイソシアナート、脂肪族モノアミンからなる転がり軸受用グリースに基づき標準グリースを製造し、これにMBPイミド10%を添加して、ROF転がり軸受用グリース試験装置中で試験する。この試験を用いて調査されたグリース組成物の寿命を測定し、かつグリースの高い使用温度を転がり軸受中で高い回転数でかつ標準的に低い軸方向及び半径方向の荷重で測定する。試験軸受として、深溝ボールベアリング6204−2Z−C3/VM104を使用し、前記ボールベアリングはアキシャル荷重で100N及びラジアル荷重で200Nの負荷、180001/minの回転数、160℃の温度にさらし、並びに1.5cm3の充填量で負荷した。イオン液体なしの前記グリース組成物は、186時間のL50値を有するが、前記グリース組成物は717時間のL50値を有することを示す。これは、イオン液体を有するグリース組成物の寿命の明らかな改善を示す。
この実施例中では、DIN51350によるVKA溶接力を測定する。このために、合成エステル、ペルフルオロポリエーテル(PFPE)、芳香族ジイソシアナート及び脂肪族及び芳香族アミンからなる混合物からなる転がり軸受用グリースを使用した。次のグリース組成物を、次にVKA−溶接力試験にかけた。
グリース1: ペルフルオロポリエーテルを有する標準
グリース2: 2.5%EMIMイミドを有するペルフルオロポリエーテルなしの標準
グリース3: 5%EMIMイミドを有するペルフルオロポリエーテルなしの標準
グリース4: 7.5%EMIMイミドを有するペルフルオロポリエーテルなしの標準
グリース5: 10%EMIMイミドを有するペルフルオロポリエーテルなしの標準
この実施例中では、DIN51350によるVKA溶接力を測定する。このために、標準組成として合成エステル、芳香族ジイソシアナート及び脂肪族アミンからなる転がり軸受用グリースを使用した。次のグリース組成物を、次にVKA−溶接力試験にかけた。
グリース1: イオン液体なしの標準
グリース2: 5%EMIMイミドを添加した標準、(油代用物)
グリース3: 10%EMIMイミドを添加した標準、(油代用物)
さらに、イオン液体の添加により温度負荷でのグリースの硬化が抑制できるかどうかを試験した。
この実施例において、イオン液体を添加する場合のホイールベアリンググリースの改善を調査する。特に貨物自動車用のホイールベアリングは、熱的にも荷重に関しても高い要求が課せられている。前記車両は、例えば山道の下り走行の際に常にブレーキをかけなければならない場合、特に高い熱的負荷が生じる。この負荷のシミュレーションのために、周期的温度切り替えを特徴とするFE8転がり軸受試験を実施する。
グリース1: 標準配合
グリース2: 標準+5%HDPイミド
これらのグリース組成物を次の表10に示す試験にかけた。
グリース3: 標準+1%HDPイミド
グリース4: 標準+2%HDPイミド
グリース5: 標準+3%HDPイミド
グリース6: 標準+1%N−エチル−3−メチルピリジニウム−ノナフルオロブタンスルホナート
グリース7: 標準+2%N−エチル−3−メチルピリジニウム−ノナフルオロブタンスルホナート
グリース8: 標準+3%N−エチル−3−メチルピリジニウム−ノナフルオロブタンスルホナート
