この加工品を塗装する場合、多くはプレス油を除く工
程（脱脂工程）を通し、金属面を清浄にして塗装してい
る。When painting this processed product, in most cases, a process for removing press oil (degreasing process) is performed to clean the metal surface before painting.
近年、塗装工程の合理化の検討が盛んに行なわれるよ
うになり、まず脱脂工程の簡略化が強く要望されてい
る。In recent years, studies on rationalization of the painting process have been actively carried out, and there is a strong demand for simplification of the degreasing process.
脱脂工程を簡略化すると当然金属面にプレス油が残る
ことがあり、塗装された塗膜が十分金属と密着せず十分
な塗膜性能を発揮できないことになる。If the degreasing process is simplified, the press oil may naturally remain on the metal surface, and the applied coating film may not sufficiently adhere to the metal, failing to exhibit sufficient coating film performance.
本発明は、従来使用されているプレス油と同等または
それ以上の潤滑特性をもち、かつ金属面に残存しても塗
膜性能に害を及ぼさない組成物を提供するにある。The present invention is to provide a composition having a lubricating property equal to or higher than that of a conventionally used press oil and having no adverse effect on coating film performance even if it remains on a metal surface.

型に積層し、長期プレス安定性に障害を及ぼしたり、プ
レス後の成型品上に残存し、塗膜外観、密着、塗膜性能
をそこなうものであってはならない。The water-based lubricating oil composition of the present invention is laminated on a press die by evaporation of water, impairs long-term press stability, or remains on a molded product after pressing, and thus the coating film appearance, adhesion, and coating film performance are improved. It shouldn't be bad.
また潤滑性能を維持するのに適当な粘度を保ちながら
プレス後塗装品表面に固形残存物の量がほとんど残らな
いように工夫したものである。Further, it is devised so that the amount of solid residue hardly remains on the surface of the coated article after pressing while maintaining an appropriate viscosity for maintaining the lubricating performance.
更に、万一プレス潤滑剤残存物が塗膜に混入しても塗
膜性能に害を及ぼさないように工夫したものである。Furthermore, even if the residue of the press lubricant is mixed in the coating film, it is devised so as not to damage the coating film performance.
