Self-lubricating organic-inorganic coating material as well as preparation method and use method thereof

The invention relates to the technical field of polymer coatings, in particular to the field of IPC C08L79, and more particularly relates to a self-lubricating organic-inorganic coating material as well as a preparation method and a use method thereof, and the self-lubricating organic-inorganic coating material comprises the following components in parts by weight: 70-130 parts of a high-temperature-resistant polymer, 5-30 parts of inorganic reinforced fibers, 0.5-4 parts of a carbon-based nano material and 20-50 parts of a solvent. The weight ratio of the inorganic reinforced fiber to the carbon-based nano material is (4-8): 1, so that the wear resistance of the coating can be effectively improved; the carbon-based nano material comprises graphene, and the inorganic reinforced fiber comprises ceramic fiber, so that the high-temperature wear resistance of the coating can be further improved, and meanwhile, the service life of the coating is prolonged; and the graphene with the layer number of 3-8 and the shee
