Abstract

The invention relates to a solid lubricant and a preparation method thereof, and belongs to the technical field of lubricant preparation. The preparation method comprises the steps of preparing a solid lubricant matrix, loading a soft metal lubricant into the solid lubricant matrix through a vacuum hot pressing method to prepare a solid lubricant crude product, and finally carrying out orthosilicic acid precipitation and hydrolysis modification on the surface of the solid lubricant crude product to finally prepare a solid lubricant finished product. The solid lubricant finished product prepared by the invention is excellent in mechanical strength, good in lubricating effect and wide in application prospect.

Description

technical field [0001] The invention relates to a solid lubricant and a preparation method thereof, belonging to the technical field of lubricant preparation. Background technique [0002] At present, solid lubrication is to replace lubricating grease with solid micropowder, thin film or composite material, and isolate the friction surface of relative motion to achieve the purpose of reducing friction and wear resistance. With the advancement of modern science and technology, in order to solve the mechanical lubrication problems under special working conditions such as high load, high vacuum, high and low temperature, strong radiation and strong corrosion, solid lubricating materials have been developed from a single micropowder, adhesive film or unit material. As a composite material composed of multiple components, the research on its mechanism of action and application methods has been developed rapidly, and many new techniques and technologies for the preparation and app...
