The invention discloses a preparation method of a self-lubricating fabric liner composite material under a high-speed working condition, which comprises the steps of dispersing phenolic resin in an organic solvent, and ultrasonically dispersing graphite fluoride and lamellar basalt scales in the organic solvent to obtain a self-lubricating fabric impregnation liquid; then repeatedly dipping the blended fiber cloth after the plasma pretreatment into the self-lubricating fabric dipping solution, and drying; and finally, adhering the fabric to the surface of the metal base material by using phenolic resin, preserving heat, curing and forming to obtain the self-lubricating liner composite material. The invention takes phenolic resin as matrix resin, takes polytetrafluoroethylene-polyisophthaloyl metaphenylene diamine blended fabric as a reinforcing phase, and greatly improves the bearing capacity of the self-lubricating liner under high-speed working conditions based on the synergistic interface physical-chemical effect of graphite fluoride and lamellar basalt scales, reduces the friction coefficient between the self-lubricating liner and a friction couple, obviously improves the wear resistance and the lubricating property of the self-lubricating liner, and greatly prolongs the service life of the corresponding self-lubricating joint bearing. |
