Problems solved by technology

[0002] Water-based metalworking fluids have been rapidly developed due to their excellent cooling, cleaning, rust resistance, economy and safety, and are widely used in metal processing fields such as cutting, grinding, calendering, stamping and tapping. , lubricating additives are an important part of water-based metalworking fluids; with the continuous strengthening of human environmental awareness and environmental protection legislation, the environmental pollution caused by mineral oil-based lubricating additives has attracted more and more attention. Water-based lubricants have It does not burn, its specific heat and thermal conductivity are greater than that of oil, clean, and cheap. It is continuously developed as a new type of green lubricating additive, and is widely used in metal processing and hydraulic transmission. It is an ideal lubricant for industrial equipment. It is the focus of the development of working fluids and process fluids. However, the current water-based lubricating additives have problems such as poor lubricity, stability and corrosion resistance, and their use is limited.
