| 摘要 |
A synthetic metal working lubricant characterized by an absence of mineral oil but which is water immiscible and dispersible in water to form oil-in-water emulsions in which said lubricant is in the discontinuous phase is prepared using polybutenes, also referred to as polyisobutylenes, having an average molecular weight within the range of approximately 320-610 constituting a principal ingredient in combination with polyethylene glycol mono- and/or diesters of higher carboxylic acids or mixtures of such acids containing 8 to 22 carbon atoms in an acyclic or branched carbon chain and/or higher fatty acids containing 8-22 carbon atoms together with optional corrosion inhibiting agents which are effective in inhibiting corrosion of ferrous and non-ferrous metals to which the lubricant is applied for the purpose of working such metals.
