Embodiment 1

[0038] 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.

[0039] 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.

[0040] 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...

Abstract

The invention discloses a water-based lubricant for metal stamping, belonging to the technical field of a lubricant for metal stamping. The water-based lubricant for metal stamping comprises the following components: polyethylene glycol, sodium polyacrylate, fatty acid amide, guar gum, sodium pyrophosphate, silica sol, polyacrylamide, dipotassium hydrogen phosphate, naphthalene sulfonate and water. According to the water-based lubricant for metal stamping and through the creative component proportion, the lubricant has good antirust performance while the good lubrication can be guaranteed; and in addition, the lubricant is convenient to clean, not only the cleaning labor intensity be greatly reduced, but also a workpiece has favorable smooth finish.

Description

technical field [0001] The invention relates to the technical field of metal stamping lubricants, in particular to a water-based lubricant for metal stamping. Background technique [0002] Stamping processing is a metal cold deformation processing method, which uses the power of conventional or special stamping equipment to directly deform the sheet metal in the mold to obtain product parts of a certain shape, size and performance. technology. Among them, sheet metal, mold and equipment are the three elements of stamping processing. Stamping has the advantages of high production efficiency, high product precision, and less raw material consumption. Due to such advantages, stamping has a wide range of applications in various fields of the national economy. [0003] Lubricants are essential in the stamping process. Lubricants not only increase the life of the die, but also improve the finish and reduce the precision of the workpiece. However, the existing oil-based lubrican...
