Example Embodiment

[0024] Example 1:

[0025] First, pour 76% base oil and 19% α-olefin into a blending kettle with a stirrer to make α-olefin synthetic oil, and then add 2.0% phosphorous bisoctyl zinc salt and 1.0 according to the mass fraction. % Tricresol phosphate, 1.0% 2,6-di-tert-butyl mixed phenol, stirred at 50-60°C for 30 minutes, and then added 0.25% heptadecenylpyrazolinenyl succinate, 0.25% organic sulfonic acid calcium salt and 0.5% polymethacrylate are stirred at 70-80°C for 90-120 minutes until the mixture is completely dissolved and uniform and transparent.

Example Embodiment

[0026] Example 2:

[0027] First, pour 78% base oil and 17% α-olefin into a blending kettle with a stirrer and mix slightly to make α-olefin synthetic oil, and then add 1.6% thion butyl octyl zinc salt and 0.8% according to the mass fraction. Triphenyl thiophosphate, 1.0% 2,6-di-tert-butyl-p-cresol, 0.5% dinonyldiphenylamine, 0.5% thiadiazole derivatives, stirred at 50-60°C for 30 minutes; Then add 0.1% dodecenyl succinic acid, 0.15% barium dinonylnaphthalene sulfonate and 0.35% polymethacrylate, stir at 70-80℃ for 90-120 minutes, until the mixture is completely dissolved and uniformly transparent .

Example Embodiment

[0028] Example 3:

[0029] First, pour 76% base oil and 20% α-olefin into a blending kettle with a stirrer and mix slightly to make α-olefin synthetic oil; then add 1.5% thionyl butyl octyl zinc salt and 0.7% according to the mass fraction. Tricresyl phosphate, 1.0% 2,6-di-tert-butyl mixed phenol, stirred at 50-60℃ for 30 minutes; then add 0.1% heptadecenylpyrazolinenyl succinate, 0.3 % Organic sulfonate calcium salt, 0.4% polymethacrylate, stirred at 70-80°C for 90-120 minutes, until the mixture is completely dissolved and uniform and transparent.

Abstract

The present invention discloses a lubricating oil capable of resisting high pressure and resisting high temperature oxidation for deep-weel electric pump and its preparation method. Its composition includes base oil, alpha-olefin synthetic oil, at least an antioxidant corrosion-resisting agent, extreme pressure phosphorus or sulfur contained ashless antiwear agent, amine high-temperature antioxidant and metal deactivator, metal cleaning agent, rust-resisting agent and pour point reducer. Said invention also can be used for making hydraulic transmission mechanical lubricating oil.

Description

technical field [0001] The invention relates to a lubricating oil for hydraulic transmission and a preparation method thereof, in particular to a high-pressure, high-temperature, oxidation-resistant and wear-resistant hydraulic lubricating oil for deep well electric pumps. Background technique [0002] Existing anti-wear hydraulic oil compound agent has "Lub.Eng." 1990, the anti-wear hydraulic oil compound agent introduced in 1 "The Evolution of petroleum Based Hydraulic Fluids" (Kent.B.Grover) has LZS5178, when the dosage is When it is 0.85-1.20% (mass fraction), it reaches Denision HF-0, HF-1, HF-2 international standards. The anti-wear hydraulic oil compound agent developed by Beijing Institute of Petrochemical Sciences has a dosage of 2.0% (mass), and the anti-wear hydraulic oil compound agent developed by Nanjing Edison Company has a dosage of 0.85% (mass). The above lubricating oils either have good wear resistance, high pressure resistance, or high temperature oxidat...
