preparation example Construction

[0039] The present invention also provides a preparation method of a gearbox lubricant composition, comprising the step of mixing the components of the composition.

[0040] Preferably, the method comprises the steps of:

[0041] (1) Pour the base oil into the stainless steel blending kettle, stir evenly, and heat up to 70-90°C;

[0042] (2) Pour the adhesive into the stainless steel mixing kettle, keep warm and stir evenly for 20-30 minutes;

[0043] (3) Pour polyurea-based grease into a stainless steel blending kettle, keep warm and stir evenly for 30-40 minutes;

[0044] (4) Cool down to 45-55°C, put anti-micropitting additives, extreme pressure anti-wear agents, antioxidants, and friction modifiers into the stainless steel blending kettle, keep warm and stir evenly for 30-40 minutes;

[0045] (5) The material in the stainless steel blending kettle is beaten out, and the finished composition is obtained after grinding.

Embodiment 1

[0048] Mix 42 parts of pentaerythritol ester base oil (U.S. Hatco company, brand: HATCOL3320, the same below) with 5 parts of cyclohexane diisocyanate (Yutai Haina Environmental Protection Technology Co., Ltd., brand: MDI-100), and heat to Dissolved at 75°C to obtain the first solution; 45 parts of pentaerythritol ester base oil and 4 parts of octadecylamine (Sichuan Tianyu Oleochemical Co., Ltd., brand: 9518) were mixed, heated to 75°C, and then 2 parts of aniline ( Dongying Longxing Chemical Co., Ltd., brand: aniline) and 2 parts of methylaniline (Shanghai Yiji Industrial Co., Ltd., brand: methylaniline), stir evenly to obtain the second solution; inject the first solution into the second solution Mix and stir at a constant temperature, then raise the temperature to 160°C, heat and stir to obtain polyurea-based grease.

[0049] Pour 23.5 parts of base oil polyalphaolefin (ExxonMobil Company of the United States, brand SPEOTRASYN40, the same below) and 25 parts of dipentaeryt...

Embodiment 2

[0051] Pour 23.5 parts of base oil polyalphaolefin and 25 parts of dipentaerythritol ester into a stainless steel blending kettle, stir evenly and raise the temperature to 80°C; put 8 parts of adhesive polyisobutylene PB24000 and double ester Priolube39867 parts into a stainless steel blending kettle, and heat evenly Stir for 30 minutes; put 30 parts of polyurea-based grease (preparation method is the same as in Example 1) into the blending kettle, keep warm and stir evenly for 40 minutes; 2.5 parts of phosphoric acid, 1 part of extreme pressure anti-wear agent methylene bis-dibutyl dithiocarbamate (Vanderbilt Company of the United States, brand Vanlube7723, the same below), 1 part of amine phosphate compound, antioxidant P, 1 part of p-octyl diphenylamine (Vanderbilt Company of the United States, brand Vanlube81, the same below), 1 part of friction modifier epoxy oleate (Wroda Company of the United Kingdom, brand PerfadFM3339, the same below), and inject The blending kettle w...

Abstract

The invention discloses a gearbox lubricating agent composition and a preparation method thereof. The gearbox lubricating agent composition comprises the following components in 100% of the total mass: 20-40% of polyurea-based lubricating grease, 20-50% of base oil, 2-4% of micro-pitting resistant additive, 1-3% of anti-wear reagent at extreme pressure, 1-5% of antioxidant, 10-20% of adhesive and 1-2% of friction modifier. The gearbox lubricating agent disclosed by the invention has excellent lubricating performance and can be used for reducing the temperature of a gearbox and avoiding the damage to a certain degree to a gear due to overhigh temperature; the gearbox lubricating agent composition has excellent low-speed and heavy-duty shear stability; according to the gearbox lubricating agent composition, the replacement period of a gearbox lubricating agent is prolonged, and the production cost is reduced; the pitting on the gear surface of the gear inside the gearbox can be effectively restricted; the gearbox lubricating agent disclosed by the invention has no any corrosion to a sealing member of the gearbox; furthermore, the risk of the lubricating agent leakage in the gearbox is eliminated.

Description

technical field [0001] The invention relates to a gearbox lubricant composition and a preparation method thereof, in particular to an anti-leakage lubricant composition applied to a gearbox reducer and a preparation method thereof, and belongs to the technical field of lubricants. Background technique [0002] The reducer is generally used for low-speed and high-torque transmission equipment. The motor, internal combustion engine or other high-speed running power is used to achieve the purpose of deceleration through the gear with a small number of teeth on the input shaft of the reducer and the large gear on the output shaft. The specific mechanism is to use the speed converter of the gear to reduce the number of revolutions of the motor to the desired number of revolutions and obtain a larger torque mechanism. Reducers are widely used in electric power, metallurgy, cement, petroleum machinery, chemical machinery and other industries, and have almost become the basis of var...
