Description
本発明は、水溶性金属加工油剤に関する。更に詳しくは、切削・研削油、塑性加工油、防錆・洗浄油、焼き入れ油などの水溶性金属加工油剤に関する。 The present invention relates to a water-soluble metalworking fluid. More specifically, the present invention relates to a water-soluble metal processing oil such as cutting / grinding oil, plastic processing oil, rust prevention / cleaning oil, quenching oil, and the like.
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）、鉱油（鉱物油）、油脂、脂肪酸、脂肪酸エステル、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。 Water-soluble processing oils used when processing metals include solution types, soluble types, and emulsion types. These are all water, alkaline substances (inorganic alkali / organic amine compounds), mineral oil (mineral oil), fats and oils, fatty acids, fatty acid esters, extreme pressure additives, surfactants, antifoaming agents, metal anticorrosives, antioxidants It contains antiseptic / antifungal agent (bactericidal agent) and the like as a composition component. These additives are produced by appropriately blending depending on the workpiece to be processed, processing conditions and other conditions.
これ等の油剤は通常、水で２〜１００倍に希釈して使用される。（希釈され使用される状態の液を以下クーラントと呼ぶ。）このクーラントには加工性に関する一次性能と作業性に関する防錆性、耐微生物劣化性、人に無害であること、などの二次性能が要求される。（耐微生物劣化性とは、微生物に因る腐敗に対する耐性のことであり、以下耐腐敗性と呼ぶ。）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、クーラントが腐敗し悪臭を発生するため周囲の作業環境を悪化させるという問題がある。 These oils are usually used diluted 2 to 100 times with water. (Liquid in a state in which it is diluted and used is hereinafter referred to as coolant.) This coolant has secondary performance such as primary performance related to workability and rust prevention related to workability, microbial degradation resistance, and harmless to humans. Is required. (Microbial degradation resistance refers to resistance to spoilage caused by microorganisms and is hereinafter referred to as spoilage resistance.) In coolants, organic substances (including nitrogen compounds) contained in oil components and processing machinery The problem is that the working environment and the lubricating oil mixed from the plant are used as nutrients by bacteria and fungi, so that the coolant rots and generates a foul odor, which worsens the surrounding work environment.
また、微生物劣化により、アルカリ性が損なわれ、被加工物の発錆問題になることがしばしばある。腐敗対策として、水溶性加工油剤中の有機アミンや防腐剤・防黴剤の種類の選定や増量が行われてきた。 Moreover, due to microbial degradation, the alkalinity is often impaired, resulting in a problem of rusting of the workpiece. As countermeasures against spoilage, selection and increase of types of organic amines and preservatives / antifungal agents in water-soluble processing oils have been carried out.
特に、防腐防黴という観点から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（特許文献１〜４）。しかし、それらはアルカリ性が強すぎ、肌荒れの問題または、近年のＰＲＴＲ法に区分されるなど安全に使用できないものであった。 In particular, amine compounds such as cyclohexylamine, dicyclohexylamine, benzylamine, dibenzylamine, xylenediamine, and N-aminopropylpiperazine have been used from the viewpoint of antiseptic and mildewing (Patent Documents 1 to 4). However, they are too alkaline and cannot be used safely, such as the problem of rough skin or the recent PRTR method.
本発明の目的は、上記問題点を解決するためになされたものであり、微生物によるクーラントの劣化に伴う発錆問題や腐敗による作業環境の悪化を防止するものである。
また、腐敗が原因で廃液とされていたクーラントの寿命を延長できることで、地球環境にも優しい加工油剤が提供される。
The object of the present invention is to solve the above-mentioned problems, and is intended to prevent the problem of rusting due to the deterioration of coolant by microorganisms and the deterioration of the working environment due to decay.
In addition, since the life of the coolant that has become waste liquid due to decay can be extended, a processing oil that is friendly to the global environment is provided.
本発明者らは、上記目的を達成すべく鋭意研究を重ねた結果、細菌対策として1,3,5-トリアジンなどのトリアジン化合物を真菌類対策としてＮ−ブチル−１，２−ベンゾイソチアゾリン−３−オンを併用し、且つアルカリ性を強めるため第１級、第２級有機アミンを特定量組み合わせることによって、相乗効果として抗菌スペクトルが広がり微生物による劣化に対し非常に有効な水溶性加工油剤を完成するに至った。 As a result of intensive studies to achieve the above object, the inventors of the present invention have used triazine compounds such as 1,3,5-triazine as a countermeasure against bacteria and N-butyl-1,2-benzisothiazoline-3 as a countermeasure against fungi. -Combined use of ON and specific amounts of primary and secondary organic amines to enhance alkalinity, and as a synergistic effect, the antibacterial spectrum spreads and a water-soluble processing oil that is extremely effective against deterioration by microorganisms is completed.

Hexahydro-1,3,5-tris (2-hydroxyethyl) -1,3,5-triazine is preferred. The triazine compound also includes a commercially available triazine preservative, and for example, Dodigen NJ (manufactured by Clariant Japan), Suneye Back P (manufactured by Sanai Oil Co., Ltd.), and the like can be suitably used.
トリアジン化合物とＮ−ブチル−１，２−ベンゾイソチアゾリン−３−オンを併用すると、耐腐敗性が向上する。 When a triazine compound and N-butyl-1,2-benzisothiazolin-3-one are used in combination, the rot resistance is improved.
配合量は、水溶性金属加工油（原液）全量基準でトリアジン化合物が０．５〜６重量％であり、１．０〜４．０重量％が好ましい。６重量％を越えるトリアジン化合物は、臭気や肌荒れが問題になる可能性があるため好ましくない。また、０．５重量％未満のトリアジン化合物では防腐効果が低下するため好ましくない。 The blending amount of the triazine compound is 0.5 to 6% by weight, preferably 1.0 to 4.0% by weight, based on the total amount of the water-soluble metalworking oil (stock solution). Triazine compounds exceeding 6% by weight are not preferred because odors and rough skin may become problems. Further, a triazine compound of less than 0.5% by weight is not preferable because the antiseptic effect is lowered.
基本的にトリアジン化合物は使用にあたっての希釈液状態で５００〜１０００ｐｐｍ含有される様配合する。

次に（Ｂ）第１級及び第２級有機アミンについて説明する。 Next, (B) primary and secondary organic amines will be described.
有機アミンは、ｐＨを上げることによりアルカリ的防錆・耐腐敗性の観点から配合している。一般に第1級アミンは、ｐＨの保持性は高く、防錆効果・及び耐細菌類に対して有効であるが肌荒れの観点からあまり多く使用できない。また第２級アミンは、防錆効果を高めるため、全体のアルカリ量を保持する為に配合される。 The organic amine is blended from the viewpoint of alkaline rust prevention and rot resistance by raising the pH. In general, primary amines have high pH retention and are effective against rust prevention and bacteria resistance, but cannot be used much from the viewpoint of rough skin. Further, the secondary amine is blended in order to maintain the entire alkali amount in order to enhance the rust prevention effect.
有機アミンは、第１級、第２級のものから選択される。第１級有機アミンとしては、モノエタノールアミン、ジグリコールアミン、モノイソプロパノールアミン、2-アミノ2-メチルプロパノールなど、第２級有機アミンとしては、ジエタノールアミン、ジイソプロパノールアミン、Ｎ−ブチルエタノールアミン、Ｎ−メチルエタノールアミン、Ｎ−エチルエタノールアミン、２−（sec−ブチルアミノ）エタノール、などが挙げられる。その中から第１級有機アミンとしてモノイソプロパノールアミン、２−アミノ−２−メチルプロパノール、ジグリコールアミン、第２級有機アミンとしてジエタノールアミン、Ｎ−メチルエタノールアミン、Ｎ−ブチルエタノールアミン、２−（sec−ブチルアミノ）エタノールが好ましい。 The organic amine is selected from primary and secondary ones.

When the total amount of the primary organic amine and / or the secondary organic amine exceeds 60% by weight, it is not preferable in terms of rough skin and cost. Further, if the total amount of the primary organic amine and / or the secondary organic amine is less than 1% by weight, it is not preferable because rust prevention and rot resistance are not recognized.
The amount of the organic amine is determined in consideration of the diluent concentration and use, rust prevention, and rot resistance in use.
