| abstract |
The present invention provides a water-soluble metal processing oil composition that is used in metal processing such as cutting, grinding, and plastic processing, has excellent microbial degradation resistance, and can sufficiently suppress the occurrence of decay and wrinkles. The water-soluble metal processing oil composition includes an alkylenediamineoxyalkylene adduct represented by the following general formula (1) (for example, ethylene oxide adduct of trimethylenediamine, ethylene oxide adduct of hexamethylenediamine, etc.) ). [Wherein R 1 , R 2 , R 3 and R 4 are each a hydrogen atom or —R 5 —H, and at least one of R 1 , R 2 , R 3 and R 4 is -R is a 5 -H. R 5 is a (poly) oxyalkylene group. x is an integer of 3-12. ] [Selection figure] None |
