Abstract

The invention provides a gear oil composition and a preparation method thereof. The gear oil composition comprises the following components in percentage by total weight of100%: 78.5-98.39% of base oil, preferably 85-97%, and more preferably 91-95%, 0.1-4% of a sulfur-containing extreme pressure agent, preferably 0.5-2%, 0.1-4% of a phosphorus-containing anti-wear agent, preferably 0.5-2%, 0.1-3% of fatty acid, preferably 0.3-2%, 0.1-1% of alkylsilane, preferably 0.5-1%, 0.3-6% of hydrophilic fumed silica, preferably 0.5-3%, 0.01-0.5% of a metal deactivator, preferably 0.03-0.1%, 0.3-3% of an antioxidant, preferably 0.5-1.5%. The gear oil composition provided by the invention sufficiently utilizes the wear reduction function of the hydrophilic fumed silica and the extreme pressure anti-wear functions of the sulfur-containing extreme pressure agent and the phosphorus-containing anti-wear agent, and is a gear oil composition with integrated functions of wear reduction, wear resistance, extreme pressure resistance, oxidation resistance and corrosion resistance.

Description

technical field

[0001] The invention relates to a gear oil composition and a preparation method thereof, belonging to the field of lubricating oil. Background technique

[0002] Gear oil is one of the three major varieties of lubricating oil, which plays a vital role in the power transmission of various equipment. Due to the heavy load of gears during work, good extreme pressure and anti-wear properties are one of the most important characteristics of gear oils. Especially with the development of machinery towards high-load, high-temperature, and high-pressure operations, it is very important for industrial The load-bearing capacity and anti-friction and anti-wear properties of gear oil are increasingly required to prevent tooth surface wear, abrasion, sintering, etc., thereby prolonging its service life and improving power transmission efficiency.
