AEROSPACE ALUMINUM ALLOY EMULSIFIED CUTTING FLUID CAPABLE OF RETARDING COLOR CHANGE

An aerospace aluminum alloy emulsified cutting fluid capable of retarding color change, prepared by the following components by weight percentage: 50-52% of naphthenic oil, 3.3-4.3% of extreme pressure lubrication corrosion inhibitor, 12-13% of oil-based lubricant, 4-6% of petroleum sodium sulfonate, 2-3% of 2-amino-2-methyl-1-propanol, 5-6% of triethanolamine, 1-2% of dicarboxylic acid rust inhibitor, 2-3% of tall oil fatty acid, 5-6% of fatty alcohol polyoxyethylene ether AEO-5, 2-3% of Span 80, 0.3-0.4% of benzotriazole, 2-3% of fungicide, 0.3-0.4% of antifungal agent, 2-3% of coupling agent, 0.1-0.2% of defoamer, and 4-5% of water. The emulsified cutting fluid can improve, by the formulation of the cutting fluid itself, the discoloration of the cutting fluid due to corruption and miscellaneous oil pollution during long-term use. La présente invention concerne un fluide de coupe émulsionné en alliage d'aluminium aérospatial capable de retarder un changement de couleur, préparé à partir des composants suiva
