NOVELTY - Composite die-doped B-N nano-graphene oxide/calcium tungstate/silica stamping die lubricating fluid comprises extreme pressure agent, dispersant, rust inhibitor and deionized water. The extreme pressure agent comprises B-N-doped nano-graphene oxide, nano-calcium tungstate and nano-silica. The dispersing agent comprises crosslinked polyvinylpyrrolidone, sodium polyacrylate, ethanol, carboxymethylcellulose and sodium tripolyphosphate. The rust inhibitor comprises petroleum sulfonate and triethanolamine borate. The weight percentage of each component is: 0.1-2 pts. wt. B-N nano graphene oxide, 0.1-1 pts. wt. nano silica, 0.1-3 pts. wt. nano-calcium tungstate, 0.5-2.5 pts. wt. crosslinked Polyvinylpyrrolidone, 0.2-2.5 pts. wt. sodium polyacrylate,1.5-3 pts. wt. ethanol, 1-5 pts. wt. carboxymethylcellulose, 0.1-3 pts. wt. petroleum sulfonate, 0.2-3 pts. wt. triethanolamine borate, 0.5-3 pts. wt. sodium tripolyphosphate and deionized water (balance). USE - Used as composite die-doped B-N nano-graphene oxide/calcium tungstate/silica stamping die lubricating fluid. ADVANTAGE - The lubricating fluid has good stability, antibacterial effect, corrosion inhibition effect, rust prevention effect and excellent lubricity. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing lubricant adding dispersant, rust inhibitor and deionized water to the reaction vessel, heating and stirring, adding extreme pressure agent, when the temperature reaches 60-80 degrees C, keep warming and continuing to stir for 25-40 minutes, stop heating and continuing to stir to room temperature.
