Traditional oil-based cutting fluids hardly meet the severe operation conditions.Hence, a kind of emulsion as extreme pressure emulsion cutting fluid was developed, which consisted of lubricant, antirust additive, stabilizer, refined mineral oil, biocide and water etc.The selection of antirust additives, oiliness additives, extreme ressure additives were discussed detailedly.The optimal composition of emulsion cutting fluid was 59.9%(mass fractions)30th transformer oil, 10.0% tetrapolyricinoleate, 5.0% dialkyl pentasulfide, 10.0% antirust compound package, 2.0% AMP-95 amine, 8.0% EN-50 emulsifier, 3.0% MBM fungicide, 2.0% 145 coupling agent and 0.1% MS 575 defoamer.The properties and characters of this new type of emulsion cutting fluid and imported similar products on the market were compared and researched.Results showed that this new type of emulsion cutting fluid was transparent and stable with good performances such as antirust, lubricating, refrigerating and cleaning properties.
