Abstract

The invention relates to an aluminum alloy cutting fluid and a preparation method thereof. The aluminum alloy cutting fluid is characterized by being prepared from the following raw materials in percentage by weight: 15-30% of naphthenic oil, 5-8% of borate containing sulfur and nitrogen, 3-5% of potassium borate, 2-4% of triethanolamine oleate, 4-8% of a non-ionic surfactant, 2-4% of an anionic surfactant, 1-3% of a corrosion inhibitor, 1-3% of an antirust agent, 0.5-2% of a stabilizer, 0.1-1.0% of a defoaming agent, 0.1-0.5% of a composite fungicide and the balance of deionized water. The aluminum alloy cutting fluid provided by the invention has good extreme pressure antiwear property, corrosion resistance, defoaming performance and stability, does not damage a cutting tool and is friction-free and wear-free to a workpiece, separation is easy during cutting, service life is long, and no pungent smell, low toxicity, environmental friendliness and easiness in cleaning and degradation are realized; and the aluminum alloy cutting fluid also has excellent cleaning and cooling performance and can rapidly take away a tremendous amount of heat and cutting powder produced during high-speed cutting processing.

Description

technical field [0001] The invention belongs to the technical field of metal cutting fluid, in particular to an aluminum alloy cutting fluid and a preparation method thereof. Background technique [0002] In the prior art, the aluminum alloy has low density, but relatively high strength and good plasticity. It can be processed into various profiles, has excellent thermal conductivity and good corrosion resistance, and is widely used in industry. inferior to steel. However, aluminum alloys have strong chemical activity, soft texture, and strong viscosity. Problems such as sticking to the knife and discoloration are prone to occur during processing. Therefore, the demand for special cutting fluids for aluminum alloy processing is also increasing. At present, during the use of aluminum alloy cutting fluids on the market, there will be oily soap in the diluent and slow emulsification speed. The incompletely emulsified oil droplets will be adsorbed on the surface of the workpiec...
