Water-based lubricant and preparing method of the same based on nanometer tungsten disulfide

Abstract

The invention discloses a water-based lubricant based on nanometer tungsten disulfide, which comprises the following components and contents, by weight, 1% to 15% of nanometer tungsten disulfide, 1% to 10% of solid lubricant, 0.2% to 3% of antirust agent, 10% to 40% of aqueous stearic acid, 10% to 20% of waterborne zinc stearate, 0.4% to 4% of emulsifying stabilizer, 0.01% to 0.05% of defoaming agent, and 8% to 77% of water. The constituent content of the components sums up to 100%. The preparing method of the water-based lubricant and a usage method thereof are disclosed. The water-based lubricant based on the nanometer tungsten disulfide has the advantages of being good in the lubrication effect of the water-based lubricant, large in elongation coefficient, environment-friendly and unpolluted, and wide in applying scope. In addition, the preparing method of the water-based lubricant and the use method and process steps thereof are simple and fast so as to improve the production efficiency and benefit the environmental protection.

Description

technical field

[0001] The invention belongs to the technical field of lubricant preparation, in particular to a water-based lubricant based on nanometer tungsten disulfide and a preparation method thereof. Background technique

[0002] In the process of metal plastic forming, the resistance of tissue tangential movement is generated between the contact surfaces when the metal to be processed and the mold move relative to each other, that is, the external friction force. The existence of external friction will increase the force and energy required for processing, so the metal surface must be lubricated. If the lubrication of the metal surface does not meet the requirements, it will aggravate the wear of the mold, and the phenomenon of adhesion and abrasion on the surface of the workpiece will occur. Therefore, lubrication and plastic forming are closely related, and the development of lubrication technology can promote the development of metal cold plastic forming. [000...
