Problems solved by technology

[0002] Gear oil is mainly made of petroleum lubricating oil base oil or synthetic lubricating oil, and it is an important lubricating oil prepared by adding extreme pressure anti-wear agent and oily agent. Gear oil for automobile transmission is mainly used for gears in automobile transmission transmission device to prevent tooth surface wear, abrasion, sintering, etc., prolong its service life, and improve power transmission efficiency; most of the current common automotive gear oils are not good enough in anti-oxidation and anti-rust performance, and the extreme pressure and anti-wear properties of gear oils poor sex

Abstract

The invention provides a gear oil formula. The formula comprises the following raw materials in percentage by weight: 5 to 15 percent of hydrotreated base oil, 1 to 5 percent of sodium sulfite, 1 to 10 percent of sodium dodecylbenzene carbonate, 5 to 15 percent of butylated hydroxytoluene, 3 to 9 percent of potassium metaborate, 2 to 3 percent of polydimethylsiloxane, 1 to 5 percent of oleamide, 11 to 19 percent of extreme pressure anti-wear agents, 5 to 7 percent of antioxidant preservatives, 3 to 5 percent of metal passivators, 3 to 5 percent of anti-rust agents, 1 to 5 percent of anti-foaming agents, 5 to 10 percent of oiliness agents, 1 to 1.5 percent of viscosity index improving agents, 4 to 5 percent of demulsifiers and 2 to 4 percent of nanometer diamond. The gear oil has very highextreme pressure anti-wear property and has high anti-oxidization performance.

Description

technical field [0001] The invention is a formula of gear oil. Background technique [0002] Gear oil is mainly made of petroleum lubricating oil base oil or synthetic lubricating oil, and it is an important lubricating oil prepared by adding extreme pressure anti-wear agent and oily agent. Gear oil for automobile transmission is mainly used for gears in automobile transmission Transmission device to prevent tooth surface wear, abrasion, sintering, etc., prolong its service life, and improve power transmission efficiency; most of the current common automotive gear oils are not good enough in anti-oxidation and anti-rust performance, and the extreme pressure and anti-wear properties of gear oils Poor sex. Contents of the invention [0003] Aiming at the above-mentioned problems in the prior art, the present invention provides a formula of gear oil, which has strong extreme pressure and anti-wear properties, and has strong anti-oxidation properties. [0004] In order to ac...
