Description
本発明は水溶性金属加工油剤のカビの繁茂を抑制するための防黴剤、それを含有する水溶性金属加工油剤組成物及びクーラントに関する。
本発明の水溶性金属加工油剤とは、水に希釈して使用される切削・研削油剤、塑性加工油剤、防錆・洗浄油剤、焼き入れ油剤などを示す。
The present invention relates to an antifungal agent for suppressing the growth of mold of a water-soluble metalworking fluid, a water-soluble metalworking fluid composition containing the same, and a coolant.
The water-soluble metalworking fluid of the present invention refers to a cutting / grinding fluid, a plastic working fluid, a rust preventive / cleaning fluid, a quenching fluid, etc. used after being diluted in water.
金属を加工する際に使用される水溶性加工油剤には、ソリューション型、ソリュブル型、エマルション型等がある。これらはいずれも水、アルカリ性物質（無機アルカリ、有機アミン化合物等）、鉱油（鉱物油等）、油脂、有機酸、有機酸エステル、極圧添加剤、界面活性剤、消泡剤、金属防食剤、酸化防止剤、防腐・防黴剤（殺菌剤等）等を組成成分として含んでいる。これ等の添加剤は加工対象被加工材、加工条件その他の条件に応じて適宜配合して製造される。一般に、水溶性加工油剤は、これを原液として、通常、水で２〜１００倍程度に希釈して使用される。以下、この水希釈された状態の液を、クーラントと言う。 Water-soluble processing oils used when processing metals include solution types, soluble types, and emulsion types. These are all water, alkaline substances (inorganic alkalis, organic amine compounds, etc.), mineral oils (mineral oils, etc.), fats and oils, organic acids, organic acid esters, extreme pressure additives, surfactants, antifoaming agents, metal anticorrosives Further, it contains antioxidants, antiseptic / antifungal agents (such as bactericides), and the like as composition components. These additives are produced by appropriately blending depending on the workpiece to be processed, processing conditions and other conditions. In general, a water-soluble processing oil is usually used as a stock solution diluted with water to about 2 to 100 times. Hereinafter, the liquid diluted with water is referred to as coolant.
クーラントでは、油剤成分中に含まれている有機物（窒素化合物を含む）や加工用機械から混入してくる作動油・潤滑油などを、細菌類・真菌類が栄養源とすることで、悪臭を発生し周囲の作業環境を悪化させるという問題がある。
またクーラントタンク壁面や配管内にカビが繁茂するとノズル詰まりが生じる、切屑に絡み付きクーラント汚れの原因となる、電気系統にカビが付着することで短絡を引き起こす。このようなカビの発生は工作物の品質低下や、配管内のカビの除去や電気系統の修理のために作業を中断せざるを得ないため、生産性の低下が生じている。
In the coolant, malodors are produced by bacteria and fungi as nutrient sources for organic substances (including nitrogen compounds) contained in oil components and hydraulic oils and lubricating oils mixed from processing machines. There is a problem that it occurs and worsens the surrounding work environment.
In addition, when mold grows in the coolant tank wall surface or piping, nozzle clogging occurs, tangled chips, and coolant contamination, causing mold to adhere to the electrical system and causing a short circuit. The occurrence of such mold causes a reduction in the quality of the workpiece, and the work must be interrupted to remove mold in the pipe and repair the electrical system, resulting in a decrease in productivity.
配管等におけるカビの繁茂を防ぐ観点から、クーラントには防黴剤、有機アミンの添加やその他成分によって防黴処理されていた。有機アミンにはシクロヘキシルアミン、ジシクロヘキシルアミン、ベンジルアミン、ジベンジルアミン、キシレンジアミン、N-アミノプロピルピペラジンなどのアミン化合物がこれまで利用されてきた。しかしながら、一般的に防黴剤は分解や不活性化により効果が時間とともに減少していく。更に従来の有機アミンを用いる場合は細菌類に対して一定の効果は有しているものの、カビに対しては抗菌性が弱く、カビの繁茂に対しては満足する結果を得ることができなかった。有機アミンを大量に含有すればカビの繁茂を抑制し得る一方、刺激性が増大することになり好ましくない。有機アミンを含有する先行技術文献は、アルキルアミンの潤滑剤としては特許文献１にジメチルラウリルアミンを含有することを特徴とするコンベヤー潤滑剤組成物の開示がある。水溶性金属加工油剤としては特許文献２にアルカノールアミンを含有することを、特許文献３にビス（２−ジメチルアミノエチル）エーテルを含有することを特徴とする特徴とする金属加工油剤の開示がある。しかしながらこの潤滑成分、水溶性金属加工油剤を使用した場合、特許文献１及び２には優れた潤滑性および加工性を発揮できるとの記載があり、特許文献３には優れた防錆性を発揮できるとあるが、カビの繁茂を抑制するかどうか記載も示唆もない。 From the viewpoint of preventing the growth of mold in piping and the like, the coolant has been subjected to antifungal treatment by adding an antifungal agent, an organic amine or other components. As organic amines, amine compounds such as cyclohexylamine, dicyclohexylamine, benzylamine, dibenzylamine, xylenediamine, and N-aminopropylpiperazine have been used. However, in general, the effect of antifungal agents decreases with time due to decomposition and inactivation. Furthermore, when conventional organic amines are used, they have a certain effect on bacteria, but their antibacterial properties are weak against mold, and satisfactory results cannot be obtained for mold overgrowth. It was. If organic amine is contained in a large amount, mold growth can be suppressed, but irritation increases, which is not preferable. Prior art documents containing organic amines disclose a conveyor lubricant composition characterized in that dimethyl laurylamine is contained in Patent Document 1 as an alkylamine lubricant. As a water-soluble metalworking fluid, Patent Document 2 discloses an alkanolamine, and Patent Document 3 discloses a metalworking fluid characterized by containing bis (2-dimethylaminoethyl) ether. . However, when this lubricating component and a water-soluble metalworking fluid are used, Patent Documents 1 and 2 describe that excellent lubricity and workability can be demonstrated, and Patent Document 3 exhibits excellent rust prevention properties. There is no description or suggestion on whether to suppress mold growth.
