Abstract

The invention discloses a preparation method of a high-and-low-temperature-resistant micro-nano lubricating material, and belongs to the technical field of lubricating materials. According to the method, firstly, cobalt nitrate and iron nitrate are dissolved and mixed; evaporative crystallization is performed to obtain uniform crystals; then, the uniform crystals are mixed with urea; through ball milling, mixed crystal powder is obtained; cooled marsh gas liquid is used as a cooling medium; oxygen is used as conveying gas; the mixed crystal powder is subjected to meltallizing in a high-energy flame spray gun through an oxyacetylene torch and enters the cooling medium to obtain micro-nano scale hollow microsphere powder; the hollow microsphere powder is uniformly mixed with surfactants such as Tween-20, and polyoxyethylene lauryl ether through heating; then, the mixture is uniformly dispersed with basic oil through ultrasound when the mixture is still hot; cooling is performed, so that the hollow microsphere powder absorbs lubricating oil; then, the temperature is raised again, and the cooling is performed again; the absorption is further performed; after the curing, the high-and-low-temperature-resistant micro-nano lubricating material is obtained. The obtained lubricating material has the advantages that the uniform dispersion is performed in high-temperature environment; the oxidation cannot easily occur; the adhesion does not occur under a low-temperature condition; the lubricating performance is excellent; wide application values are realized.
