Description
本発明は、潤滑防錆剤、特に、金属部材の潤滑、防錆に用いられて好適な潤滑防錆剤に関するものである。 The present invention relates to a lubrication and rust preventive, and more particularly to a lubrication and rust preventive suitable for use in lubrication and rust prevention of metal members.
鉱物油および有機溶剤を含み、缶スプレーにより金属部材に噴霧して当該金属部材の潤滑や防錆や、固着したネジ等の金属部材を緩めるために用いられる液状の潤滑防錆剤がある。
このような潤滑防錆剤に関し、３０〜９７質量％の炭化水素溶剤と、１〜３０質量％の揮発性シリコーンと、１〜３０質量％の炭化水素油及びこれらの混合物からなる群より選ばれる炭化水素基剤に可溶性の潤滑油を含む軽質潤滑剤がある（特許文献１）。また、冷凍機油組成物に関し、基油のＳＰ値と油溶性重合体のＳＰ値を特定した二酸化炭素冷媒用の冷凍機油組成物がある（特許文献２）。
There is a liquid lubricating rust preventive agent that contains mineral oil and an organic solvent, and is used to loosen a metal member such as a screw or the like, which is sprayed onto a metal member by can spraying to lubricate or rust the metal member.
With respect to such a lubricating antirust agent, it is selected from the group consisting of 30 to 97% by weight hydrocarbon solvent, 1 to 30% by weight volatile silicone, 1 to 30% by weight hydrocarbon oil and mixtures thereof. There is a light lubricant containing a lubricating oil soluble in a hydrocarbon base (Patent Document 1). Moreover, regarding the refrigerating machine oil composition, there is a refrigerating machine oil composition for carbon dioxide refrigerant in which the SP value of the base oil and the SP value of the oil-soluble polymer are specified (Patent Document 2).
潤滑防錆剤の特性の一つに、浸透性がある。浸透性が向上すれば、固着したネジ等の金属部材のミクロ的な隙間に潤滑防錆剤が浸透して、固着したネジ等の金属部材を従来よりも容易に、また、より短時間に緩めることができる。この点、引用文献１のような従来の潤滑防錆剤は、上記浸透性についてなお改良の余地があった。また、冷凍機油組成物は、潤滑防錆剤とは、用途も組成も特性も異なっていた。
そこで、本発明の目的は、浸透性を向上させた潤滑防錆剤を提供することにある。
One of the characteristics of a lubricating rust inhibitor is permeability. If the permeability is improved, the lubrication and rust preventive agent penetrates into the microscopic gaps of the metal member such as the fixed screw and loosens the metal member such as the fixed screw more easily and in a shorter time than before. be able to. In this regard, the conventional lubricating rust preventive agent such as cited document 1 still has room for improvement with respect to the permeability. Further, the refrigerator oil composition was different from the lubricating rust preventive agent in use, composition and characteristics.
Therefore, an object of the present invention is to provide a lubricating rust preventive having improved permeability.
本発明者は、潤滑防錆剤について鋭意研究を重ね、複数種の合成油を含み、個々の合成油のＳＰ値の差が特定値以上であることにより、浸透性を向上させることができることを見出し、本発明に至った。 The present inventor has conducted extensive research on lubricating rust preventives and includes a plurality of types of synthetic oils, and the difference in SP value of each synthetic oil is greater than or equal to a specific value, so that the permeability can be improved. The headline, the present invention has been reached.
上記知見に基づく本発明の潤滑防錆剤は、２種以上の合成油を含み、各合成油のＳＰ値のうち、最小のＳＰ値と最大のＳＰ値との差の絶対値が０．５以上であることを特徴とする。 The lubricating rust preventive agent of the present invention based on the above findings contains two or more kinds of synthetic oils, and the absolute value of the difference between the minimum SP value and the maximum SP value among the SP values of each synthetic oil is 0.5. It is the above.
本発明の潤滑防錆剤においては、上記合成油のうち、最小のＳＰ値が７〜９であり、最大のＳＰ値が９〜１１であることが好ましい。また、上記２種以上の合成油は、各合成油の４０℃における動粘度のうち、最小の動粘度と最大の動粘度との差の絶対値が５０ｍｍ２／ｓ以上であることが好ましい。
更に、上記２種以上の合成油を５〜５０質量％含むことが好ましい。また更に、本発明の潤滑防錆剤は、固体潤滑剤を含むことが好ましい。
In the lubricating rust preventive agent of the present invention, among the above synthetic oils, the minimum SP value is preferably 7 to 9, and the maximum SP value is preferably 9 to 11. Moreover, it is preferable that the absolute value of the difference of the minimum kinematic viscosity and the maximum kinematic viscosity is 50 mm < 2 > / s or more among the said 2 or more types of synthetic oil among kinematic viscosities at 40 degreeC of each synthetic oil.
Furthermore, it is preferable that 5-50 mass% of said 2 or more types of synthetic oil is included. Furthermore, the lubricating rust preventive agent of the present invention preferably contains a solid lubricant.
本発明によれば、潤滑防錆剤の浸透性を向上させることができる。 According to the present invention, the permeability of the lubricating rust inhibitor can be improved.
以下、本発明の潤滑防錆剤をより具体的に説明する。本発明の潤滑防錆剤は、２種以上の合成油を含み、各合成油のＳＰ値のうち、最小のＳＰ値と最大のＳＰ値との差の絶対値が０．５以上である。 Hereinafter, the lubricating rust preventive agent of the present invention will be described more specifically. The lubricating rust preventive agent of the present invention contains two or more kinds of synthetic oils, and the absolute value of the difference between the minimum SP value and the maximum SP value among the SP values of each synthetic oil is 0.5 or more.
本発明の潤滑防錆剤は、２種以上の合成油を含有する。合成油は鉱物油に比べて潤滑防錆剤を純度高く製造することができ、よって、不純物による油切れを抑制して高い潤滑性を得ることができる。また、合成油は、精製により良好な流動性が得られ、これにより、隙間における高い浸透性を得ることができる。 The lubricating rust preventive agent of the present invention contains two or more synthetic oils. Synthetic oil can produce a lubrication and rust preventive with a higher purity than mineral oil, and therefore can prevent oil shortage due to impurities and obtain high lubricity. Synthetic oil can be obtained with good fluidity by refining, whereby high permeability in the gap can be obtained.
合成油は、ポリα−オレフィン、ポリブテン、ポリオールエステル、二塩基酸エステル、リン酸エステル、ポリフェニルエーテル、アルキルベンゼン、アルキルナフタレン、ポリオキシアルキレングリコール、ネオペンチルグリコール、トリメチロールプロパン、ペンタエリスリトール、更にはヒンダードエステルなどのオレフィン系、エステル系、その他の合成油を挙げることができる。より好ましくは、モノエステル、ジエステル、ポリオールエステル、脂肪酸エステル、ヒンダードエステル等のエステル系合成油である。 Synthetic oils include poly α-olefins, polybutenes, polyol esters, dibasic acid esters, phosphate esters, polyphenyl ethers, alkylbenzenes, alkylnaphthalenes, polyoxyalkylene glycols, neopentyl glycols, trimethylolpropane, pentaerythritol, and more Examples include olefins such as hindered esters, esters, and other synthetic oils. More preferred are ester synthetic oils such as monoesters, diesters, polyol esters, fatty acid esters and hindered esters.
本発明の潤滑防錆剤は、２種以上の合成油の各合成油のＳＰ値（溶解パラメータ）のうち、最小のＳＰ値と最大のＳＰ値との差の絶対値が０．５以上である。このことは、潤滑防錆剤に含まれる２種以上の合成油のうち最大のＳＰを有する合成油と、最小のＳＰ値を有する合成油との、ＳＰ値の差（絶対値）が０．５以上であることを意味する。
なお、個々の合成油のＳＰ値は、計算法又は実験法により算出することができる。
The lubricating anticorrosive agent of the present invention has an absolute value of the difference between the minimum SP value and the maximum SP value of 0.5 or more among the SP values (solubility parameters) of each synthetic oil of two or more synthetic oils. is there. This is because the difference (absolute value) in SP value between the synthetic oil having the largest SP and the synthetic oil having the smallest SP value among the two or more kinds of synthetic oils contained in the lubricating rust preventive is 0. Means 5 or more.
The SP value of each synthetic oil can be calculated by a calculation method or an experimental method.
本発明の潤滑防錆剤は、最小のＳＰ値と最大のＳＰ値との差の絶対値が０．５以上であることにより良好な潤滑性を維持しつつ、浸透性を向上させることができる。その理由は、必ずしも明らかではないが、潤滑防錆剤が金属部材の表面に付着したときに、当該潤滑防錆剤に含まれる２種以上の合成油のうち、最大のＳＰを有する合成油が、潤滑防錆剤被膜の厚さ方向で金属部材の表面に近い側に位置し、最小のＳＰを有する合成油が、金属部材の表面に遠い側に位置し、被膜内で分層のような態様を示し、これにより、主に最大のＳＰを有する合成油による浸透性の向上と、主に最小のＳＰを有する合成油による潤滑性の維持とを、高いレベルで両立することができると考えられる。 The lubricating rust preventive agent of the present invention can improve the permeability while maintaining good lubricity when the absolute value of the difference between the minimum SP value and the maximum SP value is 0.5 or more. . The reason is not necessarily clear, but when the lubricating rust preventive agent adheres to the surface of the metal member, among the two or more synthetic oils contained in the lubricating rust preventive agent, the synthetic oil having the largest SP is The synthetic oil having the smallest SP is located on the side far from the surface of the metal member in the thickness direction of the lubricating rust preventive film, and is located on the side far from the surface of the metal member. In this aspect, it is considered that the improvement in permeability by the synthetic oil mainly having the largest SP and the maintenance of the lubricity by the synthetic oil mainly having the smallest SP can be achieved at a high level. It is done.
２種以上の合成油の各合成油のＳＰ値（溶解パラメータ）のうち、最小のＳＰ値と最大のＳＰ値との差の絶対値は、０．５以上で本発明で所期した効果が十分に得られ、好ましくは０．８以上であり、より好ましくは１．２以上である。 The absolute value of the difference between the minimum SP value and the maximum SP value among the SP values (solubility parameters) of each synthetic oil of two or more synthetic oils is 0.5 or more, and the effect expected in the present invention is obtained. It is sufficiently obtained, preferably 0.8 or more, and more preferably 1.2 or more.
本発明の潤滑防錆剤に含まれる２種以上の合成油のうち、最小のＳＰ値を示すものは、そのＳＰ値が７〜９程度であることが好ましい。また、本発明の潤滑防錆剤に含まれる２種以上の合成油のうち、最大のＳＰ値を示すものは、そのＳＰ値が９〜１１程度であることが好ましい。複数の合成油のうち、最小のＳＰ値を有するものと、最大の有するものとが、上記の好適なＳＰ値を有し、かつ、上述した最小のＳＰ値と最大のＳＰ値との差の絶対値が０．８以上であることが好ましい。 Of the two or more kinds of synthetic oils contained in the lubricating rust preventive of the present invention, those showing the minimum SP value preferably have an SP value of about 7-9. Of the two or more kinds of synthetic oils contained in the lubricating rust preventive of the present invention, those showing the maximum SP value preferably have an SP value of about 9-11. Among the plurality of synthetic oils, those having the minimum SP value and those having the maximum have the above-mentioned preferred SP values, and the difference between the above-mentioned minimum SP value and the maximum SP value The absolute value is preferably 0.8 or more.
本発明の潤滑防錆剤は、各合成油の４０℃における動粘度のうち、最小の動粘度と最大の動粘度との差の絶対値が５０ｍｍ２／ｓ以上であることが好ましい。このことは、潤滑防錆剤に含まれる２種以上の合成油のうち最大の動粘度を有する合成油と、最小の動粘度を有する合成油との、動粘度の差（絶対値）が５０ｍｍ２／ｓ以上であることを意味する。 In the lubricating rust preventive agent of the present invention, the absolute value of the difference between the minimum kinematic viscosity and the maximum kinematic viscosity among the kinematic viscosities of each synthetic oil at 40 ° C. is preferably 50 mm 2 / s or more. This is because the difference (absolute value) in kinematic viscosity between the synthetic oil having the maximum kinematic viscosity and the synthetic oil having the minimum kinematic viscosity among the two or more types of synthetic oils contained in the lubricating rust preventive is 50 mm. It means 2 / s or more.
上述した最小の動粘度と最大の動粘度との差の絶対値が５０ｍｍ２／ｓ以上であることにより、より浸透性が向上する。より好ましくは、最小の動粘度と最大の動粘度との差の絶対値が８０ｍｍ２／ｓ以上である。
なお、個々の合成油の４０℃における動粘度は、浸透性を考慮すると、潤滑防錆剤中の合成油が希釈剤により希釈されるとしても、あまりに大きな動粘度は好ましくなく、それぞれ１〜２００ｍｍ２／ｓ程度であることが好ましい。
When the absolute value of the difference between the minimum kinematic viscosity and the maximum kinematic viscosity is 50 mm 2 / s or more, the permeability is further improved. More preferably, the absolute value of the difference between the minimum kinematic viscosity and the maximum kinematic viscosity is 80 mm 2 / s or more.
The kinematic viscosity at 40 ° C. of each synthetic oil is not preferable even if the synthetic oil in the lubricating rust preventive agent is diluted with a diluent, considering penetrability. It is preferably about 2 / s.
本発明の潤滑防錆剤は、２種以上の合成油を合計で５〜５０質量％含むことが好ましい。５質量％以上を含むことにより、浸透性の向上と、潤滑性と、防錆性とが十分に得られる。５０質量％以下であることにより、他の成分との兼ね合いで十分な浸透性の向上と、潤滑性と、防錆性とが得られる。より好ましくは１０〜４０質量％程度である。
なお、個々の合成油の配合量については、上述した合計量の範囲内で適宜に調整すればよい。
The lubricating rust preventive agent of the present invention preferably contains 5 to 50% by mass of two or more synthetic oils in total. By including 5 mass% or more, the permeability improvement, lubricity, and rust prevention property are fully obtained. By being 50 mass% or less, sufficient permeability improvement, lubricity, and rust prevention can be obtained in consideration of other components. More preferably, it is about 10-40 mass%.
In addition, what is necessary is just to adjust suitably about the compounding quantity of each synthetic oil within the range of the total amount mentioned above.
本発明の潤滑防錆剤は、合成油以外の成分を含むことができる。合成油以外の成分としては、例えば水置換剤や表面張力低下剤や希釈剤や固体潤滑剤等が挙げられる。 The lubricating rust preventive agent of the present invention can contain components other than synthetic oil. Examples of components other than synthetic oils include water displacement agents, surface tension reducing agents, diluents, solid lubricants, and the like.
水置換剤は、潤滑防錆剤を塗布する対象物としての金属部材の表面から水分を除去して防錆効果を向上させる。水置換剤は、例えば各種の界面活性剤を用いることができる。表面張力低下剤は、浸透性を高め、また分散性を向上させる。希釈剤は、炭酸ガスやＬＰＧガス等を用いたスプレー缶で潤滑防錆剤を噴霧できるように潤滑防錆剤の成分を希釈して浸透性を高める。固体潤滑剤は、潤滑性を向上させる。 The water displacement agent removes moisture from the surface of the metal member as an object to which the lubricating rust preventive agent is applied to improve the rust prevention effect. As the water displacement agent, for example, various surfactants can be used. The surface tension reducing agent increases permeability and improves dispersibility. The diluent increases the permeability by diluting the components of the lubricating rust inhibitor so that the lubricant can be sprayed with a spray can using carbon dioxide gas, LPG gas, or the like. A solid lubricant improves lubricity.
固体潤滑剤は、炭素系ナノ粒子からなることが好ましい。フラーレン等の炭素系ナノ粒子は、一次粒子の粒径が小さく、金属部材のわずかな隙間にも固体潤滑剤が浸入することができ、金属部材の摩擦を低下して、潤滑性を向上させることができる。フラーレンは、Ｃ６０や高次フラーレンを用いることができる。炭素系ナノ粒子は、分散剤を含む潤滑防錆剤中に一次粒子として分散していることが好ましい。一次粒子径は、好ましくは１μｍ未満である。 The solid lubricant is preferably composed of carbon-based nanoparticles. Carbon-based nanoparticles such as fullerene have a small primary particle size, and a solid lubricant can enter even a slight gap between metal members, reducing the friction of metal members and improving lubricity. Can do. As the fullerene, C 60 or higher order fullerene can be used. The carbon-based nanoparticles are preferably dispersed as primary particles in a lubricating rust inhibitor containing a dispersant. The primary particle size is preferably less than 1 μm.

上記実施例及び比較例の潤滑防錆剤について、以下の浸透性試験及び潤滑性試験を行って性能を評価した。
＜浸透性試験＞
長さ３ｃｍのＭ６サイズの六角ナットのネジ孔に、長さ２．５ｃｍの雄ネジをネジ結合させた試験片を用意した。別途、ろ紙を用意した。水平台上にろ紙を置き、このろ紙上に試験片を、六角ナットのネジ穴の貫通方向が垂直方向になるように立てて置いた。試験片がろ紙上に立てられた状態で、六角ナットのネジ穴の上端には、雄ネジの上端の高さの差により深さ０．５ｃｍの窪みが形成されていた。この窪みに各実施例及び比較例の潤滑防錆剤を各々１００マイクロリットル、すなわち０．１ｃｍ３滴下し、潤滑防錆剤が六角ナットと雄ネジとの間の螺合部分の隙間を浸透し、六角ナットの下端から染み出て、ろ紙に達したことを目視で確認した。潤滑防錆剤の滴下から、ろ紙へ到達までの時間を浸透時間として計測した。この浸透時間を表１に併記する。
About the lubricating rust preventive agent of the said Example and comparative example, the following permeability test and the lubricity test were done, and performance was evaluated.
<Penetration test>
A test piece was prepared by screwing a male screw having a length of 2.5 cm into a screw hole of a M6 size hexagonal nut having a length of 3 cm. Separately, a filter paper was prepared. A filter paper was placed on a horizontal table, and a test piece was placed on this filter paper in such a way that the direction of the threaded hole of the hexagon nut was perpendicular. With the test piece standing on the filter paper, a recess having a depth of 0.5 cm was formed at the upper end of the screw hole of the hexagonal nut due to the height difference of the upper end of the male screw. 100 microliters, that is, 0.1 cm 3 each of the lubricating rust preventive agent of each of the examples and the comparative examples is dropped into this recess, and the lubricating rust preventive agent penetrates through the gap at the screwed portion between the hexagon nut and the male screw. It was confirmed visually that it oozed out from the lower end of the hex nut and reached the filter paper. The time from dripping the lubricating rust inhibitor to reaching the filter paper was measured as the permeation time. This penetration time is also shown in Table 1.
表１から、複数の合成油を用い、それらの合成油のＳＰ値の差が０．５以上の実施例１〜３は、合成油を１種のみで用いた比較例１〜３よりも浸透時間が短かった。 From Table 1, Examples 1 to 3 using a plurality of synthetic oils and having a difference in SP value of 0.5 or more of those synthetic oils penetrated more than Comparative Examples 1 to 3 using only one kind of synthetic oil. The time was short.
＜潤滑性試験＞
曽田式振子試験機により潤滑油の油性を評価する方法として、油の摩擦係数を測定した。より具体的に、振子の減衰振動を利用して、各種の潤滑油の境界油膜状態における油性を評価するための比較基準となる摩擦係数を求めた。摩擦係数の計算式は次のとおりであった。
ｆ＝Ｃ×（Ａ０−Ａｎ）／ｎ
ここに、ｆは摩擦係数、ｎは振動回数、Ａ０は初期振幅、Ａｎは各振動回数目の振れ角、Ｃは比例定数であった。求めた摩擦係数の値が小さければ油の油性効果があるといえる。
<Lubricity test>
The friction coefficient of the oil was measured as a method for evaluating the oiliness of the lubricating oil using the Kamata pendulum tester. More specifically, a friction coefficient serving as a reference for evaluating the oil properties of the boundary oil film states of various lubricating oils was determined using the damping vibration of the pendulum. The formula for calculating the coefficient of friction was as follows.
f = C × (A0−An) / n
Here, f is the friction coefficient, n is the number of vibrations, A0 is the initial amplitude, An is the deflection angle at each vibration number, and C is a proportionality constant. If the value of the obtained coefficient of friction is small, it can be said that there is an oily effect of the oil.
上述した曽田式振子試験機により実施例１〜３、比較例１〜３の摩擦係数を測定したところ、実施例１〜３の潤滑防錆剤は、比較例１〜３の潤滑防錆剤の摩擦係数と同程度であり、各実施例の潤滑性は従来例と同程度を維持できていることが分かった。 When the friction coefficients of Examples 1 to 3 and Comparative Examples 1 to 3 were measured using the Kamata-type pendulum tester described above, the lubricating rust preventives of Examples 1 to 3 were the same as the lubricating rust preventives of Comparative Examples 1 to 3. The coefficient of friction was almost the same, and it was found that the lubricity of each example could be maintained at the same level as the conventional example.
