Abstract

The invention discloses anti-wear anti-friction gear lubricating oil and a preparation method thereof. The prepared anti-wear anti-friction gear lubricating oil has high maximum anti-seize duty valueand excellent extreme pressure resistance, the friction coefficient at the load of 500N is low, and the antifriction performance is improved. After nano-zirconia is subjected to synergistic treatmentwith phosphate by utilizing petroleum sodium sulfonate, the dispersion performance is greatly improved, the nano-zirconia is difficult to aggregate and can be stably dispersed in the lubricating oil,and the anti-wear anti-friction effect is improved; and by modifying the nano-zirconia by utilizing manganese dioxide, the wear resistance and extreme pressure resistance of the nano-zirconia are improved, the compatibility of the nano-zirconia and the lubricating agent substrate is further promoted, and the anti-wear anti-friction, anticorrosive and antioxidant effects of the lubricating agent are improved.

Description

technical field [0001] The invention belongs to the technical field of gear lubricating oil, and in particular relates to an anti-wear and anti-friction gear lubricating oil and a preparation method thereof. Background technique [0002] Lubricants are widely used in aviation, automobile, machining, transportation, metallurgy, coal, construction, light industry and other industries. Gear transmission is one of the most important transmission methods in machinery. In order to prevent the gear from being worn and damaged during work, it is necessary to separate its working surface with lubricant to maintain the working efficiency of the gear mechanism and prolong its service life. According to relevant information, about 54% of mechanical failures are caused by lubrication problems, of which insufficient lubrication and improper lubrication account for 34.4% and 19.6% respectively. [0003] At present, the gear lubricating oil still has the problems of poor anti-extreme pres...
