Embodiment Construction

[0014] The present invention will be further explained below.

[0015] A kind of graphite lubricating coating for machinery, is made up of the raw material of following mass fraction:

[0016] Graphite oxide 20~30 parts

[0017] Surfactant 0.2~0.3 parts

[0018] AMP dispersant 0.5~1.5 parts

[0019] 0.2~0.4 parts of cellulose sodium salt

[0020] 5~7 parts of boron nitride

[0021] Molybdenum disulfide powder 2~4 parts

[0022] 400~440 parts of deionized water.

[0023] The preparation process is as follows: first make graphite oxide, AMP dispersant, surfactant, and cellulose sodium salt into an aqueous solution with a concentration of about 25%, then add it to a ceramic grinder, and grind at a controlled speed of 250 rpm for 3~4 hours, wait until the solution is dispersed homogeneously. Then add boron nitride and molybdenum disulfide powder, stir evenly, and send it to a mill for grinding for one hour to obtain this product, with a solid content of about 40% and a visc...

Abstract

The invention relates to a graphite lubricating coating material for machinery, wherein the graphite lubricating coating material mainly comprises graphite oxide, a surfactant, an AMP dispersant, a viscosity increasing agent, boron nitride and molybdenum disulfide powder. According to the present invention, the graphite lubricating coating material has stable gel-like shape and reliable stability,and can replace traditional mechanical lubricants such as butter and the like; by using the graphite oxide, the good lubricity is provided compared to the graphite lubricant; and by cleverly doping boron nitride and molybdenum disulfide powder into the coating material, the good thermal stability is provided.

Description

technical field [0001] The invention relates to a graphite lubricating coating for machinery. Background technique [0002] Lubricating equipment refers to the general term for a series of grease supply, grease discharge and ancillary devices that supply lubricant to lubricating parts. Mechanical equipment needs regular lubrication. In the past, the main method of lubrication was manual lubrication after a certain maintenance cycle was reached according to the working conditions of the equipment, such as buttering in popular terms. The operating environment of many large-scale mechanical equipment is relatively harsh, especially many mechanical friction pairs exposed to dusty environments and unable to use traditional lubrication methods such as lubricating oil and grease, which often lead to serious friction blockage of friction mechanism parts, Severe wear problems, and cause vibration and noise, reducing the safety reliability and service life of mechanical equipment. ...
