Abstract

The invention discloses a preparation method of a self-lubricating bearing material. Cu-BTC porous particles and pretreated nano-silicon spheres are first prepared; finally, porous carbon spheres areprepared; the prepared Cu-BTC porous particles and porous carbon spheres are mixed and added into an oleic acid lubricant and agitated, the mixture is then put into a vacuum oven and treated, centrifugal treatment is carried out after treatment is complete, and obtained precipitate is washed by adopting n-hexane and dried, so that composite porous oily particles are obtained; the prepared composite porous oily particles are added into mixed resin of epoxy resin and polyimide, agitating and mixing are performed, and a curing agent is added, and after uniform agitation, the mixture is put into amold and cured, so that a self-lubricating layer material is obtained; the surface of stainless steel as a substrate is polished, the prepared self-lubricating layer material is then directly stuck on the surface of the polished stainless steel, and thereby the self-lubricating bearing material is prepared. The properties of the self-lubricating bearing material prepared by the preparation methodare excellent, and the preparation cost is low.

Description

Technical field: [0001] The invention relates to the field of self-lubricating materials, in particular to a preparation method of self-lubricating bearing materials. Background technique: [0002] Due to the limitations of traditional lubrication methods for bearings, self-lubrication technology for bearings has become a future trend. The metal-based inlaid solid self-lubricating bearing material can realize self-lubrication without refueling or refueling at long intervals, and can realize self-lubrication under harsh working conditions such as high temperature, low temperature, pollution, corrosion, fresh water or sea water, vacuum, radiation, etc. And it has incomparable advantages such as low friction coefficient, small wear and long life. Among them, the solid lubricating material can effectively reduce friction and wear through the lubricating transfer film produced by friction with the pair friction parts, successfully breaking through the limitations of traditional ...
