Description

Technical Field

[0001] The invention relates to the technical field of cutting fluids, and in particular to a fully synthetic aluminum alloy high-gloss cutting fluid and a preparation method thereof. Background Art

[0002] Cutting fluid is an industrial liquid used in the process of metal cutting, grinding and grinding to cool and lubricate cutting tools and workpieces. It is particularly important in the processing of aluminum alloys. Aluminum alloy is a material with low density, high strength, excellent plasticity and corrosion resistance. It is mainly composed of alloy elements such as copper, zinc, manganese, silicon and magnesium. Its industrial application is second only to steel. It is widely used in aerospace, automobile manufacturing, chemical industry and other fields. Due to the low melting point, small elastic modulus and soft texture of aluminum alloy, it is easy to stick to the knife during processing. The aluminum chips generated during processing gather near the blade, which increases the difficulty of processing. It is more likely to produce welding on the blade under high temperature and high speed. The thermal expansion coefficient of aluminum alloy is high. The huge heat generated during high-speed processing can easily cause deformation of the workpiece. When processing aluminum alloys, attention should be paid to cooling. Therefore, the cutting process requires cutting fluid for cooling.

[0003] Cutting fluids are divided into oil-based cutting fluids and water-based cutting fluids. Water-based cutting fluids can be divided into emulsions, semi-synthetic cutting fluids and fully synthetic cutting fluids. The advantage of fully synthetic cutting fluids is their efficient thermal conductivity, which can quickly absorb and take away heat from the cutting area, keep the cutting area at a low temperature, and prevent thermal deformation and cracks in aluminum alloys caused by high temperatures.

[0004] Due to the material properties of aluminum alloy, the friction between the tool and the surface of the aluminum alloy during processing will cause the aluminum alloy processing surface to be oxidized or corroded, affecting the quality of the aluminum alloy processing surface.

[0005] Therefore, it is necessary to provide a new technical solution to overcome the above-mentioned defects. Summary of the invention

[0006] The object of the present invention is to provide a fully synthetic aluminum alloy high-gloss cutting fluid and a preparation method thereof which can effectively solve the above-mentioned technical problems.
