Problems solved by technology

In the past few decades, cutting fluid mainly used mineral oil emulsion as one of the main cutting fluid products, but with the gradual enhancement of people's awareness of environmental protection, the country's environmental protection has become increasingly strict, and mineral oil emulsion Products used as cutting fluids are gradually unable to meet environmental protection requirements. The main reason is that such products contain a large amount of mineral oil and emulsifiers, which cause great pollution to water bodies. In the later wastewater treatment, it is difficult to deal with them efficiently. , the cost is extremely high, and the treatment process is complicated. This problem has been plaguing the relevant personnel in the metal processing industry and sewage treatment
Although polyether-type lubricants have made great progress in lubricating performance compared with glycerin-type, polyethylene glycol-type, and borate-type lubricants, they still cannot meet high-precision metal machining, and polyether-type lubricants Lubricants are not resistant to alkaline systems, so polyether lubricants have not been able to be effectively promoted and used

Description

technical field [0001] The invention relates to the technical field of lubricants, in particular to a novel polyether ester nonionic surfactant and a preparation method thereof. Background technique [0002] The metal machining industry occupies a pivotal position in the national basic industry, with an annual output value of about hundreds of billions of yuan. In the metal machining industry, it is always inseparable from the corresponding lubricant - cutting fluid. Cutting fluid is an essential additive in the metal machining industry. It mainly plays the role of lubrication, cooling, and rust prevention, and can greatly improve the efficiency of metal machining. In the past few decades, cutting fluid mainly used mineral oil emulsion as one of the main cutting fluid products, but with the gradual enhancement of people's awareness of environmental protection, the country's environmental protection has become increasingly strict, and mineral oil emulsion Products used as c...
