摘要:
During mechanical working, an aqueous lubricant composition is used as a lubricating and cooling agent, which contains an ether phosphate as a lubricating agent. A concentrate suitable for use as a lubricant after dilution with water is also described.
摘要:
Hydrocarbon oils containing 1 to 10% emulsified water are provided, having as the emulsifier:(a) a nonionic surface-active ethylene oxide adduct having the general formula: ##STR1## in which: n.sub.1 =1 to 5;n.sub.2 =a number selected to give a polyethylene glycol chain in a weight percent within the range from about 50 to about 60% by weight of the adduct;R=alkyl of from about one to about twenty-four carbon atoms, the alkylphenyl group having from about twelve to about thirty carbon atoms; and(b) the calcium salt of dodecylbenzene sulphonic acid.The weight ratio nonionic surface-active ethylene oxide adduct to calcium salt of dodecylbenzene sulphonic acid is from about 80:20 to about 40:60. The emulsifier emulsifies from 1 to 10% by weight of water in the hydrocarbon oil.
