Problems solved by technology

[0005] In recent years, domestic iron and steel processing enterprises are facing more and more environmental protection pressure. The traditional oil-based oil-in-water (O / W) emulsion will produce a large amount of sludge and waste liquid during long-term recycling. These wastes It will cause great pollution to the production operation and the surrounding environment
In contrast, environmentally friendly water-based lubricants have excellent economy, cooling and safety characteristics, and have been widely used in cutting, drawing, grinding and other metal processing and hydraulic transmission fields, but water-based nano Rolling fluids as process lubricants during rolling are still in the field of research

preparation example Construction

[0022] A preparation method of highly dispersed nano molybdenum disulfide water-based rolling liquid, comprising the steps of:

[0023] 1) Add deionized water into the reaction kettle, add nano-molybdenum disulfide, sodium polyacrylate and sodium hexametaphosphate during the stirring process; heat the solution to 60-80°C to realize surface modification of nano-molybdenum disulfide particles and scattered;

[0024] 2) Heat the solution containing the modified molybdenum disulfide nanoparticles to 75-80°C for heat preservation, and keep stirring for 30-40 minutes; then add benzotriazole, sodium dodecylbenzenesulfonate, triethanolamine , sodium molybdate, and trisodium phosphate, heated to 80-85°C, and stirred for 35-45 minutes; then added aqueous borate and polyvinylpyrrolidone, stopped heating, and continued to stir to room temperature;

[0025]3) Ultrasonic dispersion of the solution obtained in step 2) for 30 to 45 minutes, and the finally obtained black solution is a highly...

Abstract

The invention relates to a high-dispersity nano molybdenum disulfide water-based rolling fluid and a preparation method thereof. Nano molybdenum disulfide with the particle size smaller than 50 nm, sodium polyacrylate and sodium hexametaphosphate are selected as a surface modifier and a dispersing agent, benzotriazole, sodium dodecyl benzene sulfonate, triethanolamine, sodium molybdate and trisodium phosphate are compounded to serve as an anti-rust agent, water-based boric acid ester and polyvinylpyrrolidone are used as extreme pressure agents, and deionized water is added to form the water-based nano rolling liquid with high dispersity and lubricating property. The novel molybdenum disulfide water-based nano rolling liquid is adopted to replace a traditional oil-in-water (O / W) emulsion, the development direction of energy conservation, consumption reduction, clean production and environmental protection of current metallurgical enterprises is better met, and the overall level of the steel industry in China can be improved.

Description

technical field [0001] The invention relates to the technical field of lubricant preparation, in particular to a highly dispersive nanometer molybdenum disulfide water-based rolling liquid used for lubrication in strip steel production of a cold tandem rolling mill and a preparation method thereof. Background technique [0002] Water-based lubricants have the advantages of excellent cooling performance, flame retardant, and environmental protection. Many countries are vigorously developing water-based lubricants, especially in the hydraulic and metal processing industries. Compared with oil-based lubricants, existing water-based lubricants have problems such as poor lubricity and corrosion resistance, which to a certain extent limit the development and application of water-based lubricants. With the development of nanomaterials, it provides a new idea to solve the above problems in water-based lubricants. Nanoparticles have special physical and chemical properties such as s...
