Abstract

The invention discloses a solid lubricating film. The solid lubricating film is characterized by being prepared from the following components in percentage by weight: 36 to 75 percent of a solid lubricant, 10 to 30 percent of talcum powder, 10 to 30 percent of an adhesive, 5 to 20 percent of an improver and 1 to 5 percent of a curing agent; the solid lubricant is prepared from at least two kinds of graphite, boron nitride and molybdenum disulfide; the improver is light magnesium oxide; the adhesive is phenolic resin; the curing agent is urotropin. The invention also discloses a preparation method of the solid lubricating film. According to the scheme, by using the phenolic resin as a carrier, and using the polyethylene glycol 200 as a dispersing agent, the solid lubricating film has a good wetting effect; on the basis of the characteristic of forming gradient lubrication by adding the molybdenum disulfide, the graphite, the boron nitride, the talcum powder and the like, the light magnesium oxide is added, so that the solid lubricating film has high temperature resistance, low temperature resistance, corrosion resistance and good thermal conductivity; meanwhile, the solid lubricating film has unique properties of better filling performance, relatively-high activity, relatively-high adsorption capacity, no toxicity. no harm and the like.

Description

technical field [0001] The patent of the present invention relates to the technical field of solid lubrication, in particular to a high temperature resistant solid lubricating film. Background technique [0002] Dry film lubrication is a technology that firmly bonds solid lubricants, wear-resistant additives, etc. to the moving friction surface with the help of binders to play the role of wear resistance, lubrication, and protection. It is a material that forms a dry solid lubricating dry film Known as a dry film lubricant. The dry film formed by the dry film lubricant can act as a solid lubricant under dry friction conditions, and can also be shared with lubricating oil, grease, and paste. At the same time, it also acts as an anti-corrosion protective film. It is widely used in aviation, aerospace, machinery, Friction parts in transportation, petrochemical, construction, shipbuilding, electronics and other industrial sectors. [0003] Dry film lubricants mostly use polyme...
