Abstract
Description
従来、水溶性加工油剤における耐腐敗防止性能を高める方法として、油剤のアルカリ度を高める方法が多く用いられており、そのためのアルカリ物質として、各種アミン化合物、例えば、シクロヘキシルアミン、ジシクロヘキシルアミン、アルカノールアミンなどが用いられてきた。これらの中でも、特に、ジシクロヘキシルアミンが、他のものより刺激臭が少なく耐腐敗防止性能においても有効であるとして広く用いられてきた。
しかしながら、近年、ジシクロヘキシルアミンが、人の健康や生態系に有害な恐れがある化学物質であるとして、PRTR(Pollutant Release and Transfer Register)法第1種指定化学物質に指定されたことから、その使用を控える動きがある。そのような状況の中でも、水溶性金属加工油剤の加工性能と耐腐敗防止性能を高めるためには、新たなアミン化合物が必要であった。
また、特許文献2では、4-メトキシ-2-メチルアニリン、N,N-ジメチルベンジルアミンなどの芳香族を含むアミン化合物が開示されている。さらに特許文献3では、トリエタノールアミン等、及びモノイソプロパノールアミン等並びにシクロヘキシルアミンを共に含有するアミン化合物が開示されている。
しかしながら、これらのアミン化合物には、前記ジシクロヘキシルアミンの性能を凌駕するものはなく、人の健康や生態系に害が少なく、しかも耐腐敗防止性能を高めるという本発明の目的を必ずしも充分に達成できるものではなかった。
(1)メチルジシクロヘキシルアミンを配合してなる水溶性加工油剤、
(2)さらに、脂肪酸類若しくは脂肪酸類誘導体を配合してなる上記(1)に記載の水溶性加工油剤、
(3)脂肪酸類若しくは脂肪酸類誘導体のメチルジシクロヘキシルアミン塩を配合してなる水溶性加工油剤、
を提供するものである。
当該メチルジシクロヘキシルアミンは、PRTR法第1種指定化学物質に指定された従来から使用されてきたジシクロヘキシルアミンと比べて毒性が極めて低い。毒性データは、第1表のとおりである。
1)US National Institute for Occupational Safety and Health Registry of Toxic Effects of Chemical Substances (RTECS) Database.
2)European Chemical Bureau,IUCLID Dataset(2000).
また、メチルジシクロヘキシルアミンは、毒性が低いとともに加工性能を従来より高める効果を有する。この効果は、メチルジシクロヘキシルアミンと加工油剤中に配合されて存在する種々の脂肪酸とがアミン石鹸(脂肪酸アミン塩)を形成し、それが加工性能を高める作用に寄与していると考えられる。
本発明においては、メチルジシクロヘキシルアミンの配合量(濃度)は、水で希釈する前の原液の水溶性加工油剤基準で1~50質量%であることが好ましく、3~30質量%であることがより好ましい。メチルジシクロヘキシルアミンの配合量(濃度)が、1質量%以上であれば、耐腐敗性能が良好に発現し、50質量%以下であれば、配合量に見合った性能が得られる。
脂肪酸類若しくは脂肪酸類誘導体を配合することによって、メチルジシクロヘキシルアミンなどと脂肪酸アミン塩を形成し、加工性能を高め、または乳化剤として作用して乳化安定性を高め、さらに防錆性を高める効果がある。
ここで用いる脂肪酸類若しくは脂肪酸類誘導体としては、例えば、いずれも炭素数8~30、好ましくは炭素数8~20の脂肪酸、ヒドロキシ脂肪酸、脂肪族ジカルボン酸、前記脂肪酸のダイマー酸、及び前記ヒドロキシ脂肪酸の重縮合物があげられ、それらの中から選ばれる一種又は2種以上の脂肪酸類若しくは脂肪酸類誘導体を配合することが好ましい。
前記脂肪酸、ヒドロキシ脂肪酸、脂肪族ジカルボン酸は、いずれも直鎖状若しくは分岐状のいずれであってもよく、また飽和又は不飽和のいずれでもよい。
また、脂肪酸類誘導体としてはダイマー酸やヒドロキシ脂肪酸の重縮合物(リシノール酸、12-ヒドロキシステアリン酸などの重縮合物、例えば2~6量体)などが挙げられる。
この方法であれば、水溶性加工油剤中に脂肪酸類アミン塩がより高濃度に存在し、加工性能や乳化安定性をより高めることができる場合がある。
なお、この反応は、例えば、AとB成分を、溶剤の存在下または、不存在下で、およそ室温~80℃の温度で、AとB成分を攪拌混合すればよい。
脂肪酸類若しくは脂肪酸類誘導体のアミン塩の配合量は、通常加工油剤(原液)全量基準で10~70質量%であることが好ましい。
前記塩基性化合物における有機アミン化合物としては、モノエタノールアミン、ジエタノールアミン、トリエタノールアミン、モノn-プロパノールアミン、ジ(n-プロパノール)アミン、トリ(n-プロパノール)アミン、モノイソプロパノールアミン、ジイソプロパノールアミン、トリイソプロパノールアミン、メチルイソプロパノールアミン、2-アミノ-2-メチル-1-プロパノール、N-メチルモノエタノールアミン、N-エチルモノエタノールアミン、N-n-ブチルモノエタノールアミン、N-t-ブチルモノエタノールアミン、N-シクロモノエタノールアミン、N-メチルジエタノールアミン、N-エチルジエタノールアミン、N-n-ブチルジエタノールアミン、N-t-ブチルジエタノールアミン、N-シクロヘキシルジエタノールアミンなどアルカノールアミン、及び、N-(2-ヒドロキシメチル)ピペラジン、N-(2-ヒドロキシエチル)ピペラジン、N-(2-ヒドロキシプロピル)ピペラジンなどのN-(2-ヒドロキシアルキル)ピペラジンなどのピペラジン化合物を挙げることができる。
また、アルカリ金属の水酸化物としては、水酸化ナトリウム、水酸化カリウム、水酸化リチウムなどが挙げられる。
これらの塩基性化合物は、水溶性加工油剤のアルカリ度を調整し、また、水溶性加工油剤中脂肪酸などとアミン塩やアルカリ金属塩を形成して加工性能の向上をもたらす効果がある。
この塩基性化合物の配合量は、通常他の配合成分による酸性成分を中和する中和当量近傍になるように選択すればよい。
前記ノニオン系界面活性剤としては、例えば、ポリオキシアルキレングリコール又はそのモノ、ジエーテル化合物、グリセリン若しくはそのアルキレンオキサイド付加物又はエーテル化合物等のポリオキシアルキレン系界面活性剤、カルボン酸とアルコールとのエステル、アルカノールアミンと脂肪酸又はカルボン酸とのアミド、アルキルアミンのアルキレンオキサイド付加物などが挙げられる。
