A lubricant is a lubricant that enables mechanical equipment to reduce friction during operation and is composed of a base oil and additives. The role of additives is to make the lubricant more functional. Conventional lubricants have limited lubricating capacity, and in order to improve the performance of lubricants, additives containing sulfur, phosphorus, and chlorine are usually added, but the use of such additives puts tremendous pressure on the environment. And graphene lubricant additive to improve the status quo, the graphene lubricant additives applied to lubricants, can play a friction reduction, anti-wear, anti-pressure and other functions. Graphene is a new type of carbon nanomaterials, light weight, high strength, excellent electrical and thermal conductivity, and graphene layer to layer can be sliding, anti-wear is stronger, and gradually be used in the field of lubricants.
In order to more intuitive reflection, we produced a graphene lubricant additives experimental comparison video
Graphene additives form a composite protective film in the lubricant, and this film lubrication mechanism can effectively reduce the friction factor and extend engine life. When the lubricant base oil is working, its lubrication is in a critical state, there are dry friction and film lubrication at the same time; when there is an appropriate quality fraction of graphene involved in lubrication, film lubrication dominates.
In the sliding process, the instantaneous high temperature can even melt the nanoparticles and repair the defects on the sliding surface. In addition, the carburization function of graphene can repair metal wear marks at a certain temperature and form a graphene protective film on the metal surface, thus protecting the normal operation of the engine.
Graphene has an ultra-thin lamellar structure and excellent mechanical properties, and these properties have drawn attention to its application in lubricant additives. The appropriate amount of graphene as a lubricant additive can not only significantly reduce the coefficient of friction, but also improve the lubricant’s high-temperature compression resistance and anti-friction and anti-wear performance.
Due to the very small molecular particles of graphene, there is a strong intermolecular force between the graphene layers, which makes it able to form a stable lubrication film on the surface of the friction partner, thus transforming the sliding friction into rolling friction.
Graphene has excellent lubrication performance, but its dispersion in the lubricant is poor, easy to agglomerate, and needs to be evenly and stably dispersed in the base lubricant with the aid of dispersants.
For the dispersion of graphene, CCT has developed a high-performance graphene dispersion preparation technology, which can synchronize the exfoliation preparation and functionalization modification of graphene, solving a major problem of graphene application in the field of lubrication.For the dispersion of graphene, CCT has developed a high-performance graphene dispersion preparation technology, which can synchronize the exfoliation preparation and functionalization modification of graphene, solving a major problem of graphene application in the field of lubrication.
