Problems solved by technology

However, if the same fungicide is used for a long time, the microorganisms will develop drug resistance, and the current fungicide is very toxic. After long-term contact, it will be absorbed from the skin of the human body, causing chronic poisoning and seriously endangering human health.

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 fluids, and in particular relates to an aluminum alloy cutting fluid and a preparation method thereof. Background technique [0002] In the prior art, aluminum alloys have low density, but relatively high strength, good plasticity, can be processed into various profiles, have excellent thermal conductivity and good corrosion resistance, and are widely used in industry. second to steel. However, aluminum alloys have strong chemical activity, soft texture and strong viscosity, and are prone to problems such as sticking and discoloration during processing. Therefore, the demand for special cutting fluids for aluminum alloy processing is also increasing. In the process of using the aluminum alloy cutting fluid on the market at present, the diluent will have oil soap, the emulsification speed will become slow, etc., and the oil droplets that are not fully emulsified will be adsorbed on the surfa...
