A lubricant composition comprises (1) at least one member selected from the group consisting of carboxylic acid compounds each obtained by the addition of an oxyalkylene group to a hydroxyl group of a hydroxy carboxylic acid and alkali metal salts and amine salts thereof; and (2) at least one base oil selected from the group consisting of alkyl benzene, normal paraffin, isoparaffin and &agr;-olefin. The lubricant composition is highly resistant to putrefaction when it is used as a metal-processing oil composition and shows excellent cutting characteristics in the metal-processing, which requires an extremely high lubricating action, such as form-rolling tap and deep hole boring. Moreover, the composition makes operations such as metal-processing operations easy since the liquid obtained by diluting it with water is transparent or translucent.
一种润滑油组合物包括:(1) 至少一种选自羧酸化合物组的成员,每种羧酸化合物都是通过在羟基羧酸的羟基上添加一个氧亚烷基和碱金属盐及其胺盐而得到的;(2) 至少一种选自烷基苯、普通石蜡、异链烷烃和&agr;-烯烃组的基础油。该润滑油组合物在用作金属加工油组合物时具有很强的抗腐化性,在需要极高润滑作用的金属加工(如轧制丝锥和深孔镗孔)中表现出优异的切削特性。此外,由于用水稀释后得到的液体是透明或半透明的,因此这种组合物可以使金属加工等操作变得简单。
