Abstract

The invention discloses extreme-pressure abrasion-resistant open gear oil which is prepared from the following components by weight: 20-40% of tackifier, 1-2% of rust inhibitor, 0.08-1% of antioxygen, 5-50ppm of anti-foaming agent, 0.05-0.4% of demulsifying agent, 0.002-1% of extreme-pressure abrasion-resistant agent, 0.2-2% of purification dispersant and the balance being base oil, wherein the extreme-pressure abrasion-resistant agent refers to nanometer grapheme. By adding the nanometer grapheme to serve as the extreme-pressure abrasion-resistant agent, the extreme-pressure abrasion resistance of the gear oil is improved, an abrasion-resistant effect is remarkable and the abrasion loss can be reduced by 52%; by utilizing effective adhesive, clearing agent, antirust corrosion-resistant additive and the antioxygen, the adhesion, viscosity-temperature characteristic and antioxidant rust resistance of the oil are ensured; and by adding the dispersant, the problem of blockage caused by poor dispersibility of the nanometer grapheme which serves as a solid extreme-pressure agent is solved.

Description

technical field [0001] The invention relates to a gear oil, in particular to an extreme pressure anti-wear open gear oil. Background technique [0002] The existing open gear oils generally use mineral oil as the base oil, in addition to various additives, such as detergent and dispersants, anti-oxidant and anti-corrosion agents, demulsifiers, anti-foaming agents, oily agents and extreme pressure anti-wear agents. Since gears are under heavy loads during operation, good extreme pressure and anti-wear performance is an important criterion for evaluating the quality of gear oils. [0003] Traditional extreme pressure antiwear agents are mainly sulfur-containing and phosphorus-containing. It is difficult to achieve a suitable balance between the extreme pressure and antiwear properties and high temperature stability of such compounds. At the same time, it has a negative impact on the anti-emulsification of the gear, which will reduce the strength of the oil film and cause crac...
