Description
(i)基油、水、金属塩基、および錯形成剤を含むスラリーを調製する工程であって、スラリー中の水:固体の重量比が0.15:1〜1.5:1の範囲である;
(ii)少なくとも1,000,000s−1の剪断頻度(a shear frequency)にてスラリーに剪断を加える工程;
(iii)工程(ii)から得られるスラリーをC10−C24の飽和もしくは不飽和脂肪酸またはこれらの誘導体に加えて鹸化反応を起こさせる工程であって、鹸化反応は少なくとも80℃の温度で行われる;
(iv)工程(iii)から生じる鹸化生成物から水を除去する工程;
(v)工程(iv)から得られる生成物を少なくとも190℃の温度に加熱する工程;および
(vi)工程(v)から得られる生成物を200〜150℃の範囲の温度に冷却して金属錯体グリース組成物を形成させる工程;を含む、金属錯体グリース組成物の製造方法が提供される。
驚くべきことに、本発明の製造方法は、水を蒸発させるのに必要とされるベンティング時間の短縮、全バッチ時間の短縮、よりエネルギー効率の高い製造プロセス、および生産性の上昇をもたらすということが見出された。
スラリーは、専用のスラリータンク中にて調製される。このスラリータンクは、固体(例えば、水酸化リチウム、ホウ酸、水酸化カルシウム、およびサリチル酸等)と液体(水、基油、および添加剤等)を一緒に加えて分散液もしくは“懸濁液”を調製する容器であって、次いでこの分散液もしくは“懸濁液”がオートクレーブに移送される。
本発明において使用する基油は、40℃(ASTM D445に従って)にて10〜2000mm2/sの動粘度を有するのが好ましい。
本発明の製造方法の第1の工程において作製されるスラリーは水を含む。スラリー中の水:固体の重量比は0.15:1〜1.5:1の範囲であり、好ましくは0.2:1〜1:1の範囲であり、さらに好ましくは0.2:1〜0.6:1の範囲である。驚くべきことに、本発明の製造方法により、比較的低レベルの水を加えることが可能となり、これに応じてベンティング時間が短縮される、ということが見出された。
本発明の製造方法の第2の必須工程では、スラリーが少なくとも1,000,000s−1の剪断頻度にて処理される。本発明での好ましい剪断頻度は少なくとも1,500,000s−1であり、さらに好ましくは少なくとも1,800,000s−1であり、さらに好ましくは少なくとも2,000,000s−1である。
少なくとも1,000,000s−1の剪断頻度をスラリーに加えると、スラリー中に存在する固体(例えば、リチウム塩基や錯形成剤)の粒径が、固体粒子の少なくとも90%が最大でも50μmの粒径を有するように低下するので好ましい。スラリー中に存在する固体の粒径を、0.0001μm〜200μmの範囲の平均粒径に減少させるのが好ましく、1μm〜75μmの範囲の平均粒径に減少させるのがさらに好ましく、3μm〜50μmの範囲の平均粒径に減少させるのがさらに好ましい。
高剪断ミキサーが内部スクリーンと外部スクリーンを有する場合、少なくとも1,000,000s−1の剪断頻度をもたらすのは一般に外部スクリーンである。
(1)Silverson社から市販の、モデル番号312/450MSを有する二重スクリーン角穴高剪断ミキサー;4個の内側ローターブレード、12個の外側ローターブレード、300RPMの駆動速度、7.5kWの出力定格、50Hzの周波数、12.4m/sの内側ローター先端速度、17.95m/sの外側ローター先端速度、435483s−1の内側剪断頻度、および2143393s−1の外側剪断頻度を有する;
(2)Silverson社から市販の、モデル番号450/600MSを有する二重スクリーン角穴高剪断ミキサー;4個の内側ローターブレードと12個の外側ローターブレード、300RPMの駆動速度、15kWの出力定格、50Hzの周波数、17.95m/sの内側ローター先端速度12.4m/s、23.95m/sの外側ローター先端速度、714464s−1の内側剪断頻度、および3320558s−1の外側剪断頻度を有する。
本発明の製造方法の第3の工程では、工程(ii)から得られるスラリーを、C10−C24の飽和または不飽和の脂肪酸もしくはその誘導体と接触させて、鹸化反応を起こさせる。鹸化反応は、少なくとも80℃(好ましくは少なくとも100℃)の温度で行われる。本明細書で使用している“鹸化反応”という用語は錯体形成反応を含む。さらに、本明細書で使用している“鹸化生成物”という用語は錯化生成物を含む。
表1に示すような配合処方のグリース組成物を、下記の調製方法を使用して作製した。第1の工程では、基油(全基油の10重量%の量にて)、水酸化リチウム一水和物、および水をスラリー容器に加えることによってスラリーを作製した。水:固体の重量比は約0.2〜0.4:1であった。二重スクリーン角穴を有するインライン高剪断ミキサーを使用してスラリーを20分混合した。使用したミキサーは、Silverson社から市販の、モデル番号312/450MSを有する二重スクリーン角穴高剪断ミキサーであり、4個の内側ローターブレード、12個の外側ローターブレード、300RPMの駆動速度、7.5kWの出力定格、50Hzの周波数、12.4m/sの内側ローター先端速度、17.95m/sの外側ローター先端速度、435483s−1の内側剪断頻度、および2143393s−1の外側剪断頻度を有する。ホウ酸と分散剤をスラリーに加え、再び高剪断ミキシングを行った。得られたスラリーを、基油(全基油の約50重量%の量にて)と予備溶融した12−ヒドロキシステアリン酸を含有するオートクレーブに移した。スラリータンクと高剪断ミキサー再循環ラインを基油で2回フラッシングし、フラッシング液をオートクレーブに移した。
仕上がったグリース組成物の種々の特性を、表2に示す標準的な試験法を使用して測定した。
表1に示すような配合処方のリチウム錯体グリースを、スラリーを作製するのに従来の低剪断速度のパドル/スターラー型ミキサーを使用したこと以外は、実質的に同じ調製方法を使用して作製した。さらに、水:固体の重量比は約1.5:1であった。
実施例1に対するバッチ時間は、比較例1に対するバッチ時間より47分短かった。このバッチ時間の差は、実施例1において必要とされる水の量がより少ないために、実施例1に対するベンティング時間と加熱時間がより短いことによるものであった。47分の時間節約は、比較例1と比べて実施例1に関して大幅な生産性向上をもたらす。このような大幅な生産性向上は、比較例1と実施例1との間のわずかな配合処方差によるものであるはずがない。
