[0002] Construction machinery is an important part of the equipment industry. In a nutshell, the mechanical equipment necessary for comprehensive mechanized construction projects required for earthwork construction projects, road surface construction and maintenance, mobile lifting and unloading operations, and various construction projects is called As engineering machinery, it is mainly used in national defense construction projects, transportation construction, energy industry construction and production, mining and other raw material industry construction and production, agriculture, forestry and water conservancy construction, industrial and civil construction, urban construction, environmental protection and other fields. Friction is a kind of It is an inevitable natural phenomenon that the fuel used to reduce the friction and wear of mechanical parts accounts for 1 / 3 of the total fuel consumption. In addition, friction can also cause useless loss of mechanical energy, shorten the life of the machine, and reduce the mechanical efficiency; in order to solve the above It is particularly important to find substances that can reduce friction and wear, so lubricating oil is often added, and in order to improve the tribological properties of lubricating oil, appropriate additives are often added to lubricating oil, but commercial lubricating oil additives mostly contain P, S and other harmful elements, therefore, it is of great significance to find more environmentally friendly and economical lubricating oil additives

[0003] The anti-wear agent and anti-friction agent added in the prior art are not very effective in anti-wear and anti-friction, and the anti-oxidation effect is not very obvious, which limits the technical development of lubricating oil in construction machinery
