Preparation method for molybdenum disulfide base lubricating coat

Abstract

The invention relates to a preparation method of a molybdenum disulfide-based lubricating coating, which relates to the technical field of chemical composition application. It is to wash, dry and phosphate the workpiece to be coated; then use molybdenum disulfide as a lubricant, epoxy resin as a binder, banana water as a diluent, and ethylenediamine as a curing agent. The prepared molybdenum disulfide-based lubricating coating is coated on the surface of the workpiece; under normal temperature conditions, it is naturally dried for 20-30 minutes to form a molybdenum disulfide-based lubricating coating. Compared with the prior art, it has the advantages of simple and convenient production process, low production cost and good product quality.

Description

technical field

[0001] The invention relates to a preparation method of a molybdenum disulfide-based lubricating coating, which relates to the application technical field of chemical compositions. Background technique

[0002] During the long-term use of the friction pair of the mechanical workpiece, due to the different degrees of friction between the two contact surfaces, the surface of the friction pair will be worn to varying degrees, which will affect the accuracy and operating efficiency of the workpiece in severe cases. It has been found that coating the molybdenum disulfide-based lubricating coating on the surface of the workpiece friction pair can effectively protect the friction pair from wear and reduce wear.

[0003] In the prior art, CN1420147 discloses a molybdenum disulfide-based high temperature resistant lubricating coating. Although the coating has wear-resisting, load-bearing and lubricating effects, there are also many types of raw materials required and...
