The invention relates to the field of metal surface treatment agents, and particularly discloses a low-friction-coefficient stabilizer and a preparation method thereof. The low-friction-coefficient stabilizer is prepared from the following raw materials in parts by weight: 65 to 80 parts of base oil, 4 to 6 parts of polyether modified polysiloxane, 1.5 to 3.5 parts of oleylamine modified composite lubricating filler, 1 to 2 parts of silicone oil, 0.1 to 0.3 part of antioxidant, 0.5 to 1.5 parts of molybdenum dialkyl dithiophosphate, 0.1 to 0.2 part of antirust agent and 0.2 to 0.4 part of dispersing agent, raw materials of the oleylamine modified composite lubricating filler comprise a composite filler and oleylamine accounting for 5-10% of the mass of the composite filler, wherein the composite filler comprises carbon-coated molybdenum disulfide and dimethyl imidazole cobalt-coated nano cerium dioxide in a mass ratio of (3-4.5): (4-5). The stabilizer has the advantage of being good in lubricating effect under the working conditions of high temperature and high pressure.
