Description
本発明は、水溶性金属加工油、およびそれを水で希釈した金属加工用クーラントに関する。 The present invention relates to a water-soluble metalworking oil and a metalworking coolant obtained by diluting it with water.
金属加工に用いられる金属加工油剤には油系(油性)と水系(水性)があるが、冷却性、浸潤性に優れ、火災の危険がない水性タイプが多用されている。
特に、研削用途では油剤の冷却性が重要なため、鉱油を含まないソリューション系油剤が多用される(例えば特許文献1参照)。ソリューション系油剤は、冷却性、耐腐敗性は良好であるが、潤滑性に関しては不水系、エマルション系、ソルブル系に劣る。潤滑性の不足は、加工面粗度の悪化や砥石寿命の低下、または研削焼けの原因ともなる。
そこで、ソリューション系油剤に潤滑性を付与するため、油剤にポリアルキレングリコール(PAG)を配合することが行われている(特許文献2、3参照)。
Metalworking fluids used in metalworking are classified into oil-based (oil-based) and water-based (water-based), but water-based types that are excellent in cooling and infiltration properties and do not pose a fire hazard are frequently used.
In particular, since the cooling property of the oil agent is important in grinding applications, a solution-based oil agent that does not contain mineral oil is frequently used (for example, see Patent Document 1). Solution oils have good cooling and rot resistance, but are inferior to non-water, emulsion, and solve systems in terms of lubricity. Insufficient lubricity causes deterioration of the machined surface roughness, reduction of the grinding wheel life, or grinding burn.
Then, in order to provide lubricity to a solution type oil agent, polyalkylene glycol (PAG) is mix | blended with an oil agent (refer patent document 2, 3).
特許文献2、3に記載のソリューション系油剤では、PAGの配合量を増やすことにより潤滑性は良好となる。しかし、PAGを多量に配合しても潤滑性を上げるには限界がある。そのため、厳しい加工条件では砥石と被削材間の摩擦係数が大きくなり、砥石寿命の低下や研削焼けが起こる。 In the solution oils described in Patent Documents 2 and 3, the lubricity is improved by increasing the blending amount of PAG. However, there is a limit to improving the lubricity even if a large amount of PAG is blended. For this reason, under severe processing conditions, the coefficient of friction between the grindstone and the work material increases, resulting in a decrease in the grindstone life and grinding burn.
本発明は、厳しい加工条件でも潤滑性および耐摩耗性に優れる水溶性金属加工油、およびそれを水で希釈してなる金属加工用クーラントを提供することを目的とする。 An object of the present invention is to provide a water-soluble metal working oil that is excellent in lubricity and wear resistance even under severe working conditions, and a metal working coolant obtained by diluting it with water.
本発明者らは、スルフィド構造を有するジカルボン酸と長鎖カルボン酸を併用した系において、むしろPAGを除いた方が潤滑性と耐摩耗性の双方に優れることを見いだした。本発明は、この知見をもとに完成されたものである。

R 3 —COOH (2)
Here, R 3 is a hydrocarbon group having 11 or more carbon atoms. The hydrocarbon group may be linear or branched and may be saturated or unsaturated. From the viewpoints of lubricity and wear resistance, tall oil fatty acids are preferred.
Specific examples of the long chain carboxylic acid include lauric acid, stearic acid, oleic acid, linoleic acid, linolenic acid, erucic acid, palmitic acid, ricinoleic acid, hydroxy fatty acids (eg, ricinoleic acid, 12-hydroxystearic acid, etc. ), Arachidic acid, behenic acid, melissic acid, isostearic acid, soybean oil fatty acid extracted from oil and fat, coconut oil fatty acid, rapeseed oil fatty acid, tall oil fatty acid (C18) and the like.

本加工油は、上記した(A)成分と(B)成分を、水に配合して原液としたものであるが、ポリアルキレングリコール(PAG)を含まない。ただし、不純物として本発明の効果を損なわない程度のわずかな混入は本発明の実施として認められる。
本加工油(原液)は、加工油全量基準で、(A)成分と(B)成分を合わせた配合量が4質量%以上40質量%以下であることが好ましく、より好ましい配合量は5質量%以上15質量%以下である。
(A)成分と(B)成分を合わせた配合量が4質量%未満であると、現場での本加工油使用時に水による希釈率が高すぎた場合、潤滑性の低下(摩擦係数の上昇)を招くおそれがある。一方、(A)成分と(B)成分を合わせた配合量が40質量%を超えると原液安定性が低下するおそれがある。ここで、原液安定性とは、相分離、固体の不溶解、析出等で原液の均一性がなくなることをいう。
This processing oil is obtained by blending the above components (A) and (B) with water to make a stock solution, but does not contain polyalkylene glycol (PAG). However, slight contamination that does not impair the effects of the present invention as impurities is recognized as an implementation of the present invention.
The total amount of the processing oil (stock solution) based on the total amount of the processing oil is preferably 4% by mass or more and 40% by mass or less, and more preferably 5% by mass, including the component (A) and the component (B). % To 15% by mass.
When the blending amount of the component (A) and the component (B) is less than 4% by mass, if the dilution ratio with water is too high when the processing oil is used on site, the lubricity decreases (the friction coefficient increases). ). On the other hand, when the blending amount of the component (A) and the component (B) exceeds 40% by mass, the stock solution stability may decrease. Here, the stock solution stability means that the stock solution is not uniform due to phase separation, solid insolubility, precipitation, or the like.
原液調製用の水の割合は加工油全量基準で20質量%以上75質量%以下が好ましい。水の割合が20質量%未満であると、(A)成分と(B)成分の溶解が困難となり、原液の調製が煩雑となる。また、原液調製用の水の割合が75質量%を超えると、原液としての保管量や輸送量が過大となりハンドリング性が低下する。
なお、本加工油(原液)は、そのままの濃度で使用してもよいが、好ましくは水で2倍以上200倍以下、より好ましくは5倍以上100倍以下の比率(容量比)に希釈され金属加工用クーラントとして使用される。
The proportion of water for preparing the stock solution is preferably 20% by mass or more and 75% by mass or less based on the total amount of processing oil. When the proportion of water is less than 20% by mass, it becomes difficult to dissolve the components (A) and (B), and the preparation of the stock solution becomes complicated. Moreover, when the ratio of the water for stock solution preparation exceeds 75 mass%, the storage amount and transport amount as stock solution will become excessive, and handling property will fall.
The processing oil (stock solution) may be used as it is, but is preferably diluted with water to a ratio (volume ratio) of 2 to 200 times, more preferably 5 to 100 times. Used as coolant for metal processing.
〔その他の成分〕
本加工油には、(C)成分としてノニオン系界面活性剤をさらに配合することが好ましい。このような界面活性剤を配合することにより、本加工油の濡れ性が向上し砥石と被削材との間に本加工油が浸透しやすくなる。
(C)成分としては、その効果の観点よりアセチレングリコール系界面活性剤が特に好ましい。このようなアセチレングリコール系界面活性剤としては、例えば、特開2011−12249号公報に記載されているアセチレングリコールやそのアルキレンオキサイド付加物を好適に使用可能である。例えば、アセチレングリコールEO付加物が好適である。市販品としては、エアープロダクツアンドケミカルズ製のダイノール604、サーフィノール420、サーフィノール465などが挙げられる。
(C)成分の配合量としては、原液全量基準で0.1質量%以上20質量%以下であることが好ましく、1質量%以上10質量%以下であることがより好ましい。(C)成分の配合量が多すぎると希釈時の消泡性が悪化する。
[Other ingredients]
It is preferable to further mix a nonionic surfactant as the component (C) in the processing oil. By blending such a surfactant, the wettability of the processing oil is improved and the processing oil can easily penetrate between the grindstone and the work material.
As the component (C), an acetylene glycol surfactant is particularly preferable from the viewpoint of its effect. As such an acetylene glycol-based surfactant, for example, acetylene glycol and its alkylene oxide adduct described in JP2011-12249A can be suitably used. For example, an acetylene glycol EO adduct is suitable. Examples of commercially available products include Dynol 604, Surfynol 420, Surfynol 465 and the like manufactured by Air Products and Chemicals.
The amount of component (C) is preferably 0.1% by mass or more and 20% by mass or less, more preferably 1% by mass or more and 10% by mass or less, based on the total amount of the stock solution. (C) When there are too many compounding quantities of a component, the defoaming property at the time of dilution will deteriorate.
本加工油には、(D)成分として、さらにアルカノールアミンを配合することが好ましい。このアルカノールアミンは、上述の(A)成分あるいは(B)成分と反応し、アルカノールアミンカルボン酸塩となって潤滑性をより高める。また、アルカノールアミンは、防錆剤としても機能する。
アルカノールアミンとしては、特に制限はなく、一級、二級、および三級アミンを組み合わせて使用することができる。ただし、一級アミンのみを使用するとアミンの揮発性が高く、臭気性の点で作業環境を悪化するおそれがある。それ故、一級アミンを使用する際は、二級アミンや三級アミンを組み合わせることが好ましい。また、臭気性の観点より三級アミンが好ましい。
The processing oil preferably further contains alkanolamine as component (D). This alkanolamine reacts with the above-mentioned component (A) or component (B) to become an alkanolamine carboxylate and further improve the lubricity. Alkanolamine also functions as a rust inhibitor.
The alkanolamine is not particularly limited, and primary, secondary, and tertiary amines can be used in combination. However, if only a primary amine is used, the amine is highly volatile, and the working environment may be deteriorated in terms of odor. Therefore, when a primary amine is used, it is preferable to combine a secondary amine or a tertiary amine. A tertiary amine is preferred from the viewpoint of odor.
一級アミンの具体例としては、例えば、1−アミノ−2−プロパノール、2−アミノ−2−メチル−1−プロパノール、1−アミノ−2−ブタノール、2−アミノ−1−プロパノール、3−アミノ−2−ブタノールなどが挙げられる。これらの中でも、鉄に対する防錆性の点で1−アミノ−2−プロパノールや2−アミノ−2−メチル−1−プロパノールが特に好ましい。本加工油においては、上記した成分は1種用いてもよく、2種以上を用いてもよい。
二級アミンの具体例としては、例えばジエタノールアミン、ジ(n−プロパノール)アミン、ジイソプロパノールアミン、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−シクロモノエタノールアミン、N−n−プロピルモノエタノールアミン、N−i−プロピ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−i−ブチルモノエタノールアミン、およびN−t−ブチルモノエタノールアミンなどが挙げられる。本加工油においては、上記した成分は1種用いてもよく、2種以上を用いてもよい。
Specific examples of the primary amine include, for example, 1-amino-2-propanol, 2-amino-2-methyl-1-propanol, 1-amino-2-butanol, 2-amino-1-propanol, and 3-amino- Examples include 2-butanol. Among these, 1-amino-2-propanol and 2-amino-2-methyl-1-propanol are particularly preferable from the viewpoint of rust prevention against iron. In this processing oil, the above-described components may be used singly or in combination of two or more.
Specific examples of the secondary amine include, for example, diethanolamine, di (n-propanol) amine, diisopropanolamine, N-methylmonoethanolamine, N-ethylmonoethanolamine, N-cyclomonoethanolamine, Nn-propyl. Examples thereof include monoethanolamine, Ni-propyl monoethanolamine, Nn-butyl monoethanolamine, Ni-butyl monoethanolamine, and Nt-butyl monoethanolamine. In this processing oil, the above-described components may be used singly or in combination of two or more.
三級アミンの具体例としては、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、トリエタノールアミン、N−シクロヘキシルジエタノールアミン、N−n−プロピルジエタノールアミン、N−i−プロピ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−i−ブチルジエタノールアミン、およびN−t−ブチルジエタノールアミンなどが挙げられる。上記した成分は1種用いてもよく、2種以上を用いてもよい。 Specific examples of the tertiary amine include N-methyldiethanolamine, N-ethyldiethanolamine, triethanolamine, N-cyclohexyldiethanolamine, Nn-propyldiethanolamine, Ni-propyldiethanolamine, Nn-butyldiethanolamine, N -I-butyldiethanolamine, Nt-butyldiethanolamine and the like. One kind of the above-described components may be used, or two or more kinds may be used.
上述の(D)成分の配合量は、加工油(原液)全量基準で20質量%以上55質量%以下であることが好ましい。(D)成分の配合量が20質量%未満であると、現場での本加工油使用時に水による希釈率が高すぎた場合、防錆性の低下を招いてしまうおそれがある。一方、(D)成分の配合量が55質量%を超えると原液安定性が低下する。
ここで、防錆性を高めるため、防錆剤として硫黄を含有しないカルボン酸を(D)成分と併用することが好ましい。このようなカルボン酸としては、消泡性の観点および硬水安定性の観点より、炭素原子数8から10までのカプロン酸、ノナン酸、イソノナン酸、トリメチルヘキサン酸、ネオデカン酸、およびデカン酸などのようなモノカルボン酸や、炭素原子数9から12までのノナン二酸、ウンデカン二酸、セバシン酸、およびドデカン二酸などのようなジカルボン酸が好ましく挙げられる。
特に上記したトリメチルヘキサン酸は、加工油(原液)を水で希釈した時、固形物が液面にできるのを低減する効果(硬水安定性)に優れている。
また、カルボン酸の主鎖を構成するアルキル基としては耐腐敗性の点で分岐構造を有するものが好ましい。カルボン酸としては二塩基酸を用いた方が塩として用いた場合に防錆性に優れるが、原液の安定性(不溶化しにくいこと)の観点より、二塩基酸と一塩基酸とを混合して使用することが好ましい。
The blending amount of the component (D) is preferably 20% by mass or more and 55% by mass or less based on the total amount of processing oil (stock solution). When the blending amount of the component (D) is less than 20% by mass, if the dilution ratio with water is too high when the processing oil is used in the field, the rust prevention property may be lowered. On the other hand, when the blending amount of the component (D) exceeds 55% by mass, the stock solution stability is lowered.
Here, in order to improve rust prevention property, it is preferable to use together with (D) component carboxylic acid which does not contain sulfur as a rust preventive agent. Examples of such carboxylic acids include caproic acid, nonanoic acid, isononanoic acid, trimethylhexanoic acid, neodecanoic acid, and decanoic acid having 8 to 10 carbon atoms from the viewpoint of defoaming property and stability of hard water. Preferred are monocarboxylic acids such as these, and dicarboxylic acids such as nonanedioic acid having 9 to 12 carbon atoms, undecanedioic acid, sebacic acid, and dodecanedioic acid.
In particular, the above-described trimethylhexanoic acid is excellent in the effect (hard water stability) of reducing the formation of a solid on the liquid surface when the processing oil (stock solution) is diluted with water.
Moreover, as an alkyl group which comprises the principal chain of carboxylic acid, what has a branched structure is preferable at the point of decay resistance. As the carboxylic acid, dibasic acid is superior in rust prevention when used as a salt, but from the viewpoint of stability of the stock solution (hard to insolubilize), dibasic acid and monobasic acid are mixed. Are preferably used.
また、本加工油には、本発明の目的を阻害しない範囲で各種公知の添加剤を適宜配合することができる。例えば、極圧剤、油性剤、殺菌剤(防腐剤)、金属不活性化剤、および消泡剤などである。
