Description
Technical Field
The invention belongs to the technical field of gear oil reinforcing agents, and particularly relates to a nano graphene extreme pressure antiwear restoration additive.
Background
The essence of the rubbing process is the consumption of energy and the loss of material, and it is reported that 50% to 70% of the world's energy is lost due to rubbing. 80% of machine failures are due to wear of parts. Lubrication is one of the most effective ways for friction reduction and wear resistance, and according to related organization statistics, energy loss caused by friction in the world can be reduced by 50% of the energy loss through selection of lubricants. Every improvement in the quality of the lubricant is almost the result of additive development, and most lubricants are improved by adding a plurality of lubricant additives, and the traditional additives achieve good tribological performance through physical or chemical adsorption and chemical reaction, but cannot achieve zero abrasion of materials and repair of damage to the materials.
The development of industrial gear oils relies primarily on improvements in base oil processing depth and additive performance. The base oil component generally accounts for more than 90% of the gear oil, so that the improvement of the performance of the base oil can greatly improve the performance of the industrial gear oil. Domestic and foreign researches show that the hydrogenation and isomerization dewaxing process can obtain base oil with high viscosity index and excellent oxidation resistance. Gear oil additives are important components of gear oil, and generally have three functions: protecting metal surfaces, protecting the lubricating oil itself and improving the lubricating oil performance. With the rapid development of industrial technology, a single type gear oil additive cannot meet the requirements of modern industry, and the existing gear oil additive product mainly appears in the form of a compound type additive. The gear oil additive with excellent comprehensive performance is obtained by reasonably matching single agents with excellent performance so as to meet the requirements of actual working conditions.
With the intensive research on antiwear and antifriction lubricant additives, many researchers have proposed the concept of lubricant additives with self-repairing function in order to make the material have the function of automatically repairing the worn surface during the friction process. However, in the prior art, the lubricating additive with the self-repairing function is relatively rare, and the scheme aims to provide the gear oil reinforcing agent which is capable of increasing the pressure resistance of the gear oil, prolonging the service life of the gear oil and having the self-repairing function on the basis of not changing the effect of the original gear oil.
Disclosure of Invention
Aiming at the situation and overcoming the defects of the prior art, the invention provides the nano graphene extreme pressure anti-wear repair additive which is safe, non-toxic and non-dangerous in the preparation process, increases the pressure resistance of the gear oil, prolongs the service life of the original gear oil, re-forms a film on the surface of the metal gear, enables the surface of the metal friction pair to be changed from the original sliding friction into rolling friction, increases the extreme pressure capability of the surface of the friction pair by times, and has a quick repair effect on tiny wound surfaces generated by friction.
