Document Type and Number:
WIPO Patent Application WO/2021/134939
Kind Code:
A1
Abstract:
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.
