Embodiment 1

[0022] Particle classification (micron)

Embodiment 2

[0024] Weigh 1000g of molybdenum disulfide coarse powder and put it into a stirring mill, then put in 5kgΦ5mm~10mm zirconia balls, then add 800ml of industrial ethanol, after ball milling for 40h, take out the slurry, dry and heat at 80°C. Put 1000g of dried molybdenum disulfide into a polyurethane ball mill tank, and then put it into a Φ30mm polyurethane core-spun ball, and continue ball milling for 2 hours to produce a finished product.

Embodiment 3

[0026] Weigh 1000g of molybdenum disulfide coarse powder and put it into the stirring mill, then put in 8kgΦ5mm~10mm zirconia balls, then add 900ml of industrial ethanol, after ball milling for 30h, take out the slurry, dry and heat at 80°C. Put 1000g of dried molybdenum disulfide into a polyurethane ball mill tank, and then put it into a Φ30mm polyurethane core-spun ball, and continue ball milling for 2 hours to produce a finished product.

Abstract

The invention relates to a method to manufacture molybdenum disulfide powder. The process includes the following steps: adding ball mill medium, large aggregate molybdenum disulfide powder, disperse liquid into high power whisking burnishing-machine to take waterproof pulverization; drying the slurry by blast dryer; and taking the second pulverization on the ball mill. The invention solves the problem of returning to coarse phenomenon of superfine powder existing in drying process.

Description

Technical field: [0001] The invention relates to an ultra-fine processing technology of molybdenum disulfide powder, which can realize industrial production, and the technology can be widely used in the ultra-fine processing of non-metallic powder with a layered structure. Background technique: [0002] As a functional filler in coatings, ultrafine flaky powders have been the focus of research in the field of pigments and fillers at home and abroad in recent years. Due to the characteristics of the ultrafine powder itself, it will greatly improve the comprehensive properties of the coating such as density, surface finish and bonding force, and the "labyrinth" effect of the two-dimensional nano flake powder in the coating, all of which make this Ultrafine two-dimensional nanopowders are increasingly becoming the focus of coating researchers. [0003] In order to prepare a sealing, self-lubricating and anti-wear coating for the engine lubricating oil casing, it is necessary t...
