Embodiment 1
[0024] A water-based lubricant for metal stamping in this embodiment, each component is composed of the following parts by mass: polyethylene glycol 22 kg, sodium polyacrylate 25 kg, fatty acid amide 26 kg, gull gum 12 kg, sodium pyrophosphate 4 kg, 5 kg of silica sol, 21 kg of polyacrylamide, 2 kg of dipotassium hydrogen phosphate, 3 kg of naphthalene sulfonate, and 880 kg of water.
[0025] It is worth noting that the polyethylene glycol makes the lubricant have good lubricating properties, and the polyethylene glycol is PEG-3000. The molecular weight of the sodium polyacrylate is 2000-3000, and the fatty amide is also called N.N-bishydroxyethyl alkylamide, coconut acid diethanolamide, coconut oil diethanolamide and the like.
[0026] In addition, it must be noted that the guar gum is a water-soluble polymer, and its chemical name is guar gum hydroxypropyltrimethylammonium chloride. The sodium pyrophosphate in this example is also called tetrasodium phosphate, sodium pyroph...
