The electric automobile lubricating oil composition provided by the invention comprises the following components: (a) an ashless dispersant; (B) a viscosity index improver; (C) extreme pressure antiwear agent; (D) an antioxidant; (E) a benzotriazine metal deactivator; (F) a lubricating base oil; the structure of the benzotriazine derivative is shown as a formula (I): Wherein R 1、R2 is independently selected from the group consisting of C 4～C20 linear or branched alkyl, R 3 is selected from the group consisting of H, C 1～C10 linear or branched alkyl, halogen, R 4 COO-, linear or branched alkyl of C 1～C10 substituted with halogen or R 4 COO-, and R 4 is selected from the group consisting of C 1～C10 linear or branched alkyl. The electric automobile lubricating oil composition has excellent electrical insulation performance, high bearing performance and copper corrosion resistance.
Description
Technical Field
The invention relates to a lubricating oil composition, in particular to an electric automobile lubricating oil composition and a preparation method thereof.
Background
Under the large background of the double-carbon strategic target, electric automobiles are rapidly developed. The technical development requirements of small-size light-weight and low energy consumption of the electric automobile enable the motor and the transmission system to be in an integrated design, so that the motor and the transmission system share one set of lubrication system to become the development trend of the lubrication oil product of the electric automobile. The highest rotating speed of the motor can reach over 20000r/min, and the higher input rotating speed brings harsh requirements to the wear resistance and the bearing performance of the transmission system. In addition, a large amount of insulating materials and copper wires are wrapped in the motor, so that the electric automobile oil product is also required to have good electrical insulation and copper corrosion resistance.
In general, high load bearing and corrosion protection properties of oil products are contradictory. The introduction of extreme pressure antiwear agents has a great influence on the corrosion performance of oil products, for example, the introduction of very small amounts of sulfur-containing extreme pressure antiwear agents causes great corrosion to copper. Therefore, how to balance the high bearing performance and copper corrosion resistance of the electric automobile lubricating oil product is an important point and a difficult point in the development of the electric automobile lubricating oil product. In order to obtain a lubricating oil composition having a satisfactory performance, development of high-performance additives and formulation techniques are required.
At present, research reports on the lubricating oil composition of the electric automobile are reported at home and abroad.
CN 113454193a discloses a lubricating oil composition comprising alkaline earth metal detergent, sulfur compound, ZDDP and other phosphorus compounds, which has better wear resistance and sintering resistance.
CN110225962a discloses a lubricating oil composition comprising one or more thiadiazole compounds, which improves the seizure and copper corrosion resistance of the oil.
CN1102234744a discloses a lubricating oil composition comprising a polymethacrylate viscosity index improver of specific structure, an antiwear agent with antiwear and extreme pressure functions and an extreme pressure agent, resulting in a lubricating oil composition with better fatigue resistance and shear stability.
The above documents relate to an electric car lubricating oil composition to which a metal-containing or sulfur-containing compound is added for improving the wear resistance and load bearing properties of the composition, but the introduction of ash and sulfur elements is disadvantageous from the standpoint of environmental protection and compatibility with motor insulation materials, and thus has a certain limitation in its application.
Disclosure of Invention
