PURPOSE:A water-soluble oil for skinpass rolling that contains a water-soluble cation obtained by neutralizing a condensation product between a specific aliphatic dicarboxylic acid and a specific polyamine with a specific oxyacid of phosphorus and a water-soluble anticorrosive, thus having lubricating and cleaning actions. CONSTITUTION:The objective fluid for skinpass rolling contains (A) a water- soluble anticorrosive and (B) a water-soluble cation which is obtained by neutralizing a condensation product between (i) an aliphatic dicarboxylic acid of 6- 22 carbon atoms and at least one polyamine selected from (ii) compounds of formula I -III (R1-R4, R7 are H 1-3C alkyl; R5, R6 are 1-4C alkylene; n is 3-5) and hydroxyl-containing basic nitrogen compounds such as ethylaminoethanolamine and 1,3-diamino-2-propanol, with (iii) at least one oxyacid of phosphorus selected from phosphoric, phosphorous and pyrophosphoric acid and the compound of formula IV. EFFECT:The final anticorrosive oil can be applied uniformly, without causing stickiness and at a low cost. |
