さび止め油は、金属材料が各種加工され、または洗浄等された後に、金属材料表面に被膜させることがある。加工油、洗浄液などが水系のものである場合、加工油、洗浄液が原因となってサビが発生するのを防止するために、さび止め油は、加工油や洗浄液を金属表面から除去した上で金属表面に被膜させる必要がある。 In general, a metal material made of a metal such as iron is applied with rust prevention oil on the metal surface in order to prevent rust and stain from being generated on the metal surface during the manufacturing process or after the product is shipped. On the other hand, the metal material is subjected to various types of processing such as cutting and pressing using a processing oil, and may be cleaned using a cleaning liquid during the manufacturing process.
The rust preventive oil may be coated on the surface of the metal material after the metal material is variously processed or cleaned. If the processing oil or cleaning fluid is water-based, rust prevention oil must be removed after removing the processing oil or cleaning fluid from the metal surface in order to prevent rusting due to the processing oil or cleaning fluid. It is necessary to coat the metal surface.

On the other hand, the metal material is subjected to various types of processing such as cutting and pressing using a processing oil, and may be cleaned using a cleaning liquid during the manufacturing process.
The rust preventive oil may be coated on the surface of the metal material after the metal material is variously processed or cleaned.

It is necessary to coat the metal surface.
したがって、水系の加工液等を用いた後にさび止め油を被膜する場合には、通常、水除去性に優れた油剤を塗布して水分を除去した後、防錆性に優れたさび止め油を金属表面に塗布する。なお、水除去性とは、金属表面に付着した水と金属の間に添加剤が入り込み、金属表面から水を除去する性能をいう。水除去性に優れた油剤としては、例えば、特許文献1に記載されるように、非水溶媒と、カチオン活性剤、又は高級アミン若しくはそのカルボン酸塩等からなる界面活性剤とを含む水置換剤が知られている。
Therefore, when coating rust-preventing oil after using water-based processing fluid, etc., after removing water by applying an oil agent with excellent water removal properties, rust-preventing oil with excellent rust prevention properties is usually applied.

As an oil agent having excellent water removability, for example, as described in Patent Document 1, a water replacement containing a non-aqueous solvent and a surfactant composed of a cationic surfactant, a higher amine or a carboxylate thereof, or the like. Agents are known.
また、工程を簡略化するために、水除去性に優れた油剤等を塗布して水分を除去する工程を省略することも試みられている。この場合、さび止め油は、暴露環境下における防錆性のみならず、水除去性も良好にする必要がある。そのようなさび止め油を提供することを目的として、従来、低粘度鉱油と、高粘度鉱油と、脂肪酸アミン塩と、エステルと、ザルコシン型化合物等の防錆剤とを含有するさび止め油が開発されている(例えば、特許文献2参照)。
Also, in order to simplify the process, an attempt has been made to omit the process of removing moisture by applying an oil agent or the like excellent in water removability. In this case, it is necessary that the rust preventive oil not only has rust prevention properties in an exposed environment but also has good water removability. For the purpose of providing such rust-preventing oil, conventionally, a rust-preventing oil containing a low-viscosity mineral oil, a high-viscosity mineral oil, a fatty acid amine salt, an ester, and a rust inhibitor such as a sarcosine-type compound, It has been developed (see, for example, Patent Document 2).
しかし、水除去性を付与するための添加剤(水除去剤)と、防錆性を付与するための添加剤(防錆剤)は、いずれも金属表面に吸着することで、水除去性や防錆性を付与している。そのため、水除去性と防錆性の両立を図るために、水除去剤と防錆剤の両方をさび止め油に配合すると、これらは金属表面に競争吸着してしまうと考えられており、一般的に、水除去性と防錆性の両立を図るのは困難である。
例えば特許文献2に開示されるさび止め油組成物でも、脂肪酸アミン塩が水除去剤の働きをすると考えられ、水除去剤と防錆剤の両方が配合されるが、暴露環境下における防錆性を十分に高めることは難しい。 However, the additive (water removing agent) for imparting water removability and the additive (rust preventing agent) for imparting rust prevention property are both adsorbed on the metal surface, Rust prevention is given. Therefore, in order to achieve both water-removability and rust-preventive properties, it is thought that when both a water-removing agent and a rust-preventing agent are blended with rust-preventing oil, these will be competitively adsorbed on the metal surface. In particular, it is difficult to achieve both water removability and rust prevention.
For example, in the rust-preventing oil composition disclosed in Patent Document 2, it is considered that the fatty acid amine salt functions as a water removing agent, and both the water removing agent and the rust preventive agent are blended. It is difficult to increase sex sufficiently.

さらに、さび止め油組成物を金属材料に塗布するとき、例えば、金属材料をさび止め油組成物に浸漬するが、浸漬時に金属材料表面に付着していた水分がさび止め油組成物に混入することがある。したがって、さび止め油組成物に混入した水をさび止め油組成物から分離して除去するために、さび止め油組成物には実用的には水分離性が必要とされる。
本発明は、以上の事情に鑑みてなされたものであり、本発明の課題は、水除去性、防錆性、及び水分離性を良好にすることが可能なさび止め油組成物を提供することである。 Furthermore, when applying a rust preventive oil composition to a metal material, for example, the metal material is immersed in the rust preventive oil composition, but moisture adhering to the surface of the metal material at the time of immersion is mixed into the rust preventive oil composition. Sometimes. Therefore, in order to separate and remove the water mixed in the rust preventive oil composition from the rust preventive oil composition, the rust preventive oil composition practically requires water separability.
This invention is made | formed in view of the above situation, The subject of this invention provides the rust prevention oil composition which can make water removal property, rust prevention property, and water separation property favorable. That is.
