Abstract

The invention discloses a preparation method of a tungsten diselenide nano-clathrate. The preparation method is as follows: tungsten powder and selenium powder which are in a certain molar ratio and graphite are used, absolute alcohol is added to prepare raw material mixture, the mixture is processed to form paste, and the paste performs solid-phase synthesis under a certain condition to obtain the tungsten diselenide nano-clathrate with a core-shell structure. The product has uniform size and large specific surface area; the product still has good mechanical properties and wear resistance under extreme conditions such as high temperature and high pressure and has good dispersibility in macromolecular composite and other composites; and the product is a lubricating material with good performance, has simple preparation process, controllable parameters and safe and environmentally friendly production process and is particularly suitable for large-scale industrial production.

Description

technical field

[0001] The invention relates to a preparation method of a lubricating material, more specifically, a preparation method of a tungsten diselenide nano inclusion compound. Background technique

[0002] WS 2 Is a similar graphite, molybdenum disulfide (MoS 2 ) solid lubricating material with a layered structure, its thermal conductivity is about one hundred thousandth of that of diamond with the best thermal conductivity, and it is the material with the lowest thermal conductivity in the world, so it has the characteristics of high temperature resistance and corrosion resistance. The performance of vacuum exhaust is also better than that of graphite and molybdenum disulfide. It can be used under severe working conditions such as heavy load, corrosive medium, vacuum, and high temperature. It has broad application prospects in aerospace and other fields. In addition, due to its high conversion efficiency and stability, it is also an excellent semiconductor mater...
