Embodiment

[0013] The specific process steps for preparing molybdenum disulfide are carried out in three steps

[0014] A. Preliminary preparation; wash the workpiece with metal cleaning agent, rinse with water, and dry it; conventional medium temperature phosphating treatment, the thickness of the phosphating layer is 0.01mm.

[0015] B. Coating preparation: According to the weight ratio of 2:1, take molybdenum disulfide and epoxy resin for blending; dilute with banana water, and adjust its viscosity. Every time you adjust, you need to use a viscometer to detect it. The viscosity is 20 seconds, and 2% of ethylenediamine is added by weight percentage, and stirred evenly; filtered twice with a 700-mesh screen to prepare a molybdenum disulfide-based lubricating coating.

[0016] C. Coating method: Take the paint and apply it evenly on the surface of the workpiece that has been phosphated by brushing. The amount of paint is 120g / m 2 , the dry film thickness is 25 μm; at intervals of 10 hou...

Abstract

The invention discloses a preparation method of molybdenum sulfide base lubricant coating, relating to the application technical field of chemical compound. The procedures of the invention are: cleaning the workpiece which is to be coated, and then drying and parkerizing; the molybdenum sulfide base lubricant dope is made with molybdenum sulfide as lubricant, epoxy resin as caking agent, banana oil as diluting agent and ethylenediamine as firming agent, the molybdenum sulfide base lubricant dope is then pasted on the surface of the workpiece; at the normal temperature, the molybdenum sulfide base lubricant coating is prepared with the molybdenum sulfide base lubricant dope naturally dried for 20 to 30 min. As compared with the prior art, the invention has the advantages of convenient art, low 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...
