<p>The present invention relates to an oil-soluble phosphonium dithiocabamate-based ionic liquid, a method for preparing the same, and a rolling oil composition having the same. More specifically, the ionic liquid is represented by chemical formula 1 consisting of a phosphonium cation and a dithiocabamate anion, and has excellent thermal stability, low-temperature fluidity, heat resistance, and abrasion resistance, thereby being added to the rolling oil composition in such a manner that the rolling oil composition has a high flash point, a low pour point, and excellent load resistance, abrasion resistance, and frictional coefficient. In the chemical formula 1, R′, R′′, and R_1 to R_4 are same as defined in the specification.</p> |
