Description
他の目的は、潤滑組成物、特にグリースの代りの製造方法を提供することである。
(a)任意に1種以上の添加剤を含有する基油組成物を供給する(provide)工程、
(b)1種以上のアルキル置換キノリン又はそのオリゴマー誘導体の溶剤溶液を供給する工程、及び
(c)工程(b)の溶液を150℃未満の温度で工程(a)の基油組成物に添加する工程、
を少なくとも含む潤滑組成物、特にグリースの製造方法を提供することにより得られる。
(但し、R1〜R8は、独立に水素又は炭素原子数1〜8のアルキル基から選択され、nは0、1、2又は3である)
を有する。
また前記溶液に供給される1種以上のアルキル置換キノリンの溶解度は、ASTM D893で測定して0.1%未満であることが好ましい。
本発明方法に使用される溶剤に関しては特別の制限はなく、各種の慣用の溶媒が都合良く使用できる。
一例として、ポリアルキレングリコール(PAG)は、モノマー単位として、炭素原子数が1〜6のアルキレンオキシド単位(−R−O−)を表すことができる。
複合エステルは、多価アルコールと、1価酸及びC4〜C12ジカルボン酸のような2価酸との比例(proportional)エステル化により製造できる。この方法では二量体及び三量体が形成される。アルコール基としてネオペンチルグリコール及び/又はトリメチロールプロパンを用いる場合の複合エステルが好ましい。
鉱油としては、液体石油、及び溶剤処理又は酸処理した、パラフィン性、ナフテン性又はパラフィン性/ナフテン性混合型の鉱物性潤滑油(更に水素化仕上げ法及び/又は脱蝋により更に精製してよい)が含まれる。
本発明において“グループI”基油、“グループII”基油及び“グループIII”基油とは、米国石油協会(API)基準I、II及びIIIの定義による潤滑油基油を意味する。このようなAPI基準は、APIパブリケーション1509、第15版、付録E、2002年4月に定義されている。
以下に本発明を下記実施例を参照して説明するが、これらの実施例は本発明の範囲をいかなる方法でも限定することを意図するものではない。
溶液A:
2,2,4−トリメチル−1,2−ジヒドロキノリンオリゴマー(固体;Rhein Chemie Rheinau GmbHから“Additin RC7010”の商品名で得られる)を添加する前にポリアルキレングリコール(The Dow Chemical Company,米国から“Oxilube 504”の商品名で得られる)を100℃に加熱して、2,2,4−トリメチル−1,2−ジヒドロキノリンオリゴマーの50%m/mポリアルキレングリコール溶液500mlを製造した。2,2,4−トリメチル−1,2−ジヒドロキノリンオリゴマーを約2分間に亘ってゆっくり添加し、更にこれを添加する前に液体中に分散させた。こうして得られた混合物を100℃で更に30分間撹拌した。安定な均質溶液が形成された。
溶液Aと同様に、2,2,4−トリメチル−1,2−ジヒドロキノリンオリゴマーの50%m/mポリグリコール(The Dow Chemical Company,米国から“Synalox 50−50B”の商品名で得られる)溶液500mlを製造した。安定な均質溶液が形成された。
前記溶液A(50ml)及び従来のグリース基材(4950g)を用いてグリースを製造した。
従来のグリース基材は、リチウム錯体増粘剤 約10%m/mと、SN 500及びブライトストック(ASTM D445による40℃での粘度=180mm2/g)をブレンドしたパラフィン性鉱物基油約90%m/mとを含有する。また従来のグリース基材は、耐摩耗剤(ジアルキルジチオ燐酸亜鉛)、極圧添加剤(硫化エステル)及び錆防止剤(ナフテン酸亜鉛)も含有する。
得られたグリースは、視覚検査で明確な欠陥は見られなかった。塊も形成されなかった。また12カ月の保存後、グリースからの2,2,4−トリメチル−1,2−ジヒドロキノリンオリゴマーの分離は起こらなかった。
得られたグリースの他の特性を下記表Iに示す。
実施例1と同様に、溶液Bを用いてグリースを製造した。
得られたグリースは、視覚検査で明確な欠陥は見られなかった。塊も形成されなかった。また12カ月の保存後、グリースからの2,2,4−トリメチル−1,2−ジヒドロキノリンオリゴマー 2,2,4−トリメチル−1,2−ジヒドロキノリンの分離は起こらなかった。実施例1と同様、実施例2のグリースも機械的安定性、油保留性及び水安定性の所望特性を示した。
2,2,4−トリメチル−1,2−ジヒドロキノリンオリゴマー(溶剤なし)及び実施例1、2の同じグリース基材を用いてグリースを製造した。
グリース基材を約160℃に加熱した。次いで、この固体2,2,4−トリメチル−1,2−ジヒドロキノリンオリゴマーの一部を加熱グリース基材に加え、この温度で約10分間放置した。この混合物が約60℃の温度に達するまで、実験室用櫂形撹拌機を用いて混合を行った。
得られたグリースは、視覚検査で明確な欠陥は見られなかった。塊も形成されなかった。
加熱を(約160℃の代りに)約60℃とした他は、比較例1と同様に、グリースを製造した。
固体2,2,4−トリメチル−1,2−ジヒドロキノリンオリゴマーをグリース基材中に分散できず、比較例2のグリースを例えばグリース分配システムに使用した場合は、厳しいフィルター目詰まりが起こる。
実施例から判るように、本発明は、アルキル置換キノリン又はそのオリゴマー誘導体をかなり低温で添加しても、なお所望特性を有する判定なグリースを得ることができる。これが健康及び安全の観点からも、また実際の製造上の観点からも非常に望ましいことは言うまでもない。
これに関連して、アルキル置換キノリン又はそのオリゴマー誘導体を添加中、溶剤を使用しない(比較例2参照)と、安定なグリースが得られないことが注目される。
