Abstract

The invention discloses a preparation method and application of a nano MoS2-loaded carbon material compound. A carbon material is prepared from graphene, a carbon nanotube, fullerene C60 and fullereneC70. The nano MoS2-loaded carbon material compound prepared by the preparation method disclosed by the invention can form a stable dispersion system in synthetic lubricating oil, and shows excellentantiwear and friction reducing performance within a range of 50 to 125 DEG C.

Description

technical field [0001] The invention relates to a carbon material loaded nano-MoS 2 The preparation method and application of the compound. Background technique [0002] With the rapid development of science and technology, modern industrial equipment is faced with more severe service conditions, such as high speed, heavy load and high temperature, all of which will lead to an increase in the surface temperature of the friction pair. In the current lubricant service environment, there are many actual working conditions with temperatures higher than 200°C or 300°C. For example, for the next generation of high-temperature-resistant aircraft engine oil, it is expected to be able to adapt to the working temperature of 260-427°C. Many equipment in the metallurgical industry need to work Lubricating grease with a temperature as high as 200-300°C. In order to meet the lubrication requirements under high temperature and severe working conditions, many synthetic base oils, such as ...
