Description
1.発明の分野
本発明は、金属加工液(metal working fluid)及びその使用に関する。より詳細には、本発明は、水性アルカリ性金属加工液及びその濃縮物、並びに微生物増殖の可能性を低減させながらそれらを使用するためのプロセスに関する。該プロセスは、水性アルカリ性金属加工液又は金属加工環境中のマイコバクテリウム(Mycobacterium)の存在を減少させる。
非水性、油性の機能性流体組成物のコストの増大及び処分の問題は、水性の機能性流体組成物の需要を加速させている。水性金属加工液は、その経済的な、環境上の、また安全上の利点のために、非水性金属加工液よりも重要性が高まっている。水性の金属加工液は、当技術分野でよく知られているチップ成形及び非チップ成形金属加工プロセス、例えば、穿孔、タッピング、ブローチング、研削、圧延、延伸、スピニング加工、フライス加工、曲げ加工、旋削、及びスタンピングに使用されている。
a)式Iaの各R1が、独立して、C6~C8アルキルであり得る、金属加工液;
b)式Ibの各R2が、独立して、C6~C7アルキルであり得る、金属加工液;
c)式Iaにおいて、C5~C10アルキルが、ジメチルヘキシル、エチルヘキシル、ヘプチル、又はオクチルを含む、金属加工液;
d)式Ibにおいて、C5~C8アルキルがペンタメチレンを含み、C6シクロアルキレンがシクロヘキシレンを含む、金属加工液;
e)水性アルカリ性金属加工液の総重量を基準として、約0.2~15重量%、好ましくは1~7重量%の少なくとも1種のアミンを含む、金属加工液;
f)エーテル基を含むアミン、トリアジン、ホウ素、ジシクロヘキシルアミン、及びそれらの組み合わせから選択される少なくとも1種の材料を含まない、金属加工液;
g)約0.2~20重量%の酸系pH緩衝剤、及び最大25重量%の非ゼロ量の有機アミンpH緩衝剤を含む、金属加工液;
h)水、少なくとも1種のpH緩衝剤、殺生物剤、消泡剤、及び任意選択で、腐食防止剤、乳化剤、又は潤滑剤添加物を、望ましくは、水性金属加工液の総重量を基準として、約0.05~2重量%の殺生物剤、約0.05~2重量%の消泡剤、約0.2~20重量%のpH緩衝剤、最大25重量%の非ゼロ量の乳化剤、又はそれらの組み合わせを含む、金属加工液;
i)最大50重量%の非ゼロ量の流体力学的潤滑剤添加物、最大40重量%の非ゼロ量の境界潤滑剤添加物、及び最大40重量%の非ゼロ量の極圧潤滑剤添加物を含む、金属加工液;
j)12~16個の炭素原子を有する有機カルボン酸、ベンゾトリアゾール、トリルトリアゾールのナトリウム塩、又はそれらの組み合わせを含む少なくとも1種の腐食防止剤を含む、金属加工液;
k)鋳鉄腐食防止剤、イエローメタル腐食防止剤、又はアルミニウム腐食防止剤、望ましくは、水性金属加工液の総重量を基準として、最大15質量%の非ゼロ量の鋳鉄腐食防止剤、最大5重量%の非ゼロ量のイエローメタル腐食防止剤、及び最大5重量%の非ゼロ量のアルミニウム腐食防止剤、のうちの1又は複数。
水性アルカリ性金属加工液は、少なくとも1種の式(Ia)、(Ib)、又は(Ic)のアミンを含む:
式IaにおけるR1は、独立して、C2~C18アルキル又はC4~C16アルキルであり得る。あるいは、R1は、独立して、C5~C12アルキルであり得る。好ましくは、少なくとも1つのR1がC6~C8アルキルである。さらにより好ましくは、式Iaのアミンは、ジメチルヘキシルアミン、2-エチルヘキシルアミン、ヘプチルアミン、又はオクチルアミンであり得る。
式IbにおけるR2は、独立して、C5~C8アルキル又はC6シクロヘキシレンであり得る。好ましくは、少なくとも1つのR2は、C7~C8アルキル又はシクロヘキサンである。さらにより好ましくは、式Ibのアミンは、2-メチルペンタン-1,5-ジアミン又は1,4-シクロヘキサンジアミンであり得る。)
最小発育阻止濃度試験(MIC)
静生物剤候補の最小発育阻止濃度(minimum inhibitory concentration)を決定するための接種ブロスは、金属加工環境で過去に使用されており、かつ細菌源としてグラム陰性細菌の存在の検査で過去に陽性を示した従来の水性半合成金属加工液を使用して、微生物産業で知られているように調製した。先ず金属加工液を培養して細菌の濃度を高め、接種物を生成した。次いで接種物を下記のように使用して、静生物剤候補を含有する金属加工液試料について最小発育阻止濃度試験を行い、金属加工液に対するアルキルアミンの阻害効果を評価した。
下記表Iに従って金属加工液を調製した:
実施例1~7及び比較例C1~C14は、アミン系静生物剤を、中間体中に、金属加工液の総重量を基準として3重量%の量で添加することによって調製した。実施例1~7及び比較例C1~C14中に添加したアミン系静生物剤の式を表IIに記載する。
実施例5はDCHAよりも優れていたが、本発明に係る実施例の中では最も僅差であった。スクリーニング試験において、DCHAに対して、同様の、しかし改善された性能を有する候補として、実施例5を、マイコバクテリウム接種金属加工液に対する静生物有効性を試験するために選択した。
