Description

technical field [0001] The invention relates to a synthetic cutting fluid containing nano-particle molybdenum sulfide and a preparation method thereof, belonging to the technical field of metal cutting fluids. Background technique [0002] Metal cutting fluid is a kind of industrial liquid used for cooling and lubricating in metal cutting process, such as cutting, grinding and cutting. Rust and other effects, and can effectively extend the tool life. Because the existing traditional oil-based cutting fluid contains more base oil, it not only causes a great waste of energy, but also has a serious impact on the environment and endangers the personal health of operators. With the enhancement of people's awareness of environmental sanitation, the traditional oil-based cutting fluid is gradually developing towards the green and environment-friendly water-based cutting fluid. Contents of the invention [0003] In view of the deficiencies in the prior art, one of the objectives...
