Abstract

The invention discloses a preparation method of a water-based lubricant for metal stamping, and belongs to the technical field of lubricants for metal stamping. The preparation method comprises the following steps: (1) preparing a mixture A: mixing components such as polyethylene glycol and sodium polyacrylate; (2) preparing a mixture B: heating the mixture A; (3) preparing a mixture C: adding components such as silica sol and polyacrylamide in the mixture B; (4) preparing the water-based lubricant: adding naphthalenesulfonate in the mixture C to prepare the lubricant. Through the creative component ratio, the lubricant has favorable anti-corrosion performance while ensuring the favorable lubricating property, and in addition, the lubricant is convenient to clean, and not only greatly reduces the cleaning labor intensity, but also endows a workpiece with a favorable degree of finish.

Description

technical field [0001] The invention relates to the technical field of metal stamping lubricants, in particular to a preparation method of 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 exi...
