Abstract

The invention relates to the technical field of industrial lubricating oil, and discloses a preparation method of fireproof, flame-retardant, and wear-resistant hydraulic oil. The method comprises thefollowing steps: respectively putting 70-80 parts of base oil and 15-20 parts of pentaerythritol tetraisooctanoate into a blending kettle according to mass percentage for blending, and then heating,mixing and stirring uniformly. The preparation method of the fireproof, flame-retardant, and wear-resistant hydraulic oil improves degree of fusion between the raw materials and improves the quality of the product, by putting 70-80 parts of the base oil and 15-20 parts of pentaerythritol tetraisooctanoate into a blending kettle, first heating the blending kettle, and then stirring uniformly. By putting 1-2 parts of tritolyl phosphate, 3-5 parts of zinc dialkyl dithiophosphate, 0.5-0.1 part of thiadiazole derivative, 2-4 parts of polymethacrylate, 1-2 parts of barium dinonylnaphthalenesulfonate, and 0.2-0.3 part of methylsilicone oil in the blending kettle, controlling the temperature at 50-60 DEG C, stirring for 1-2 hours, the various raw materials are thoroughly mixed at suitable temperature; and multi-functional components are added for stirring.

Description

technical field [0001] The invention relates to the technical field of industrial lubricating oil, in particular to a preparation method of a fire-proof, flame-retardant and wear-resistant hydraulic oil. Background technique [0002] Hydraulic oil is the hydraulic medium used in the hydraulic system using liquid pressure energy. It plays the role of energy transmission, anti-wear, system lubrication, anti-corrosion, anti-rust and cooling in the hydraulic system. For hydraulic oil, it should first meet the requirements of the hydraulic device. Requirements for liquid viscosity at working temperature and starting temperature, since the viscosity change of lubricating oil is directly related to hydraulic action, transmission efficiency and transmission accuracy, it is also required that the viscosity-temperature performance and shear stability of the oil should meet the requirements of different uses various needs. [0003] According to Chinese patent CN 104263480 A, a fire-re...
