Problems solved by technology

[0003] Nanomaterials have the characteristics of small size, high specific surface area and surface energy, so they are prone to agglomeration and deposition in solution, which affects practical applications
The extremely poor dispersion stability of most inorganic nanomaterials in base oil also limits their application as lubricating additives

Abstract

The invention discloses a preparation method of lubricating oil added with a nanomaterial. The preparation method comprises the following steps: (1) stirring nanosheets of a layered transition metal chalcogenide compound and an active modifier for mixing uniformity; (2) carrying out ultrasonic oscillation treatment on a material obtained in step (1) at 25-80 DEG C, and then stirring for 0.5-10 hours at room temperature to obtain a modified nanosheet mother liquor; (3) carrying out suction filtration on the nanosheet mother liquor, cleaning with an organic solvent to remove the residual activemodifier, and drying to obtain a modified nanosheet; (4) adding the modified nanosheet into base oil, and fully dispersing to obtain a main component; and (5) adding an assistant into the main component, and stirring to obtain the lubricating oil added with the nanomaterial.

Description

technical field [0001] The invention belongs to the technical field of nano lubricating oil, and in particular relates to a preparation method of lubricating oil added with nano material. Background technique [0002] With the continuous development of nano science and technology, more and more nano materials are used in lubrication systems, so the application field of nano lubricating additives has emerged. Five types are most commonly used as nano-lubricating additives: (1) zero-dimensional solid particles, such as silica nanoparticles, metal nanoparticles and metal oxide nanoparticles; (2) zero-dimensional hollow nanoparticles, such as fullerenes and Its derivatives, and WS2 / MoS2 hollow nanoparticles; (3) one-dimensional nanoparticles, such as carbon nanotubes, ZnS / WS2 / MoS2 metal sulfide nanorods, and Mo-S-I / Mg 2 B 2 o 5 Nanowires; (4) two-dimensional layered nanoparticles, such as metal disulfide salts, clays, layered binary hydroxides (LDHs), layered metal phosphates...
