Description
Technical Field
The invention belongs to the technical field of nano antiwear agents, and particularly relates to a novel nano antiwear agent and a production device thereof.
Background
Nanomaterials have received much attention due to their special physical and chemical properties and have been primarily used in many fields. In the field of tribology, a great deal of research has been conducted on nanoparticle lubricating oil additives. It has been found that various nano-metal particles as additives are effective in improving the anti-friction, anti-wear and extreme pressure properties of oils. It is noted that the nano metal particle additive with high chemical activity and surface activity is difficult to maintain chemical and physical stability for a long time during the storage and use of the lubricating oil, and the easy agglomeration property of the nano metal particles makes it difficult to maintain dispersion stability for a long time in the lubricating oil, which greatly limits the application of the nano metal particle lubricating oil additive. The previous research shows that an organic molecule modification layer can be introduced on the surface of the nano metal particles by virtue of the chemical adsorption property of the organic micromolecule ligand to the solid surface, so that the dispersion stability of the nano metal particles in lubricating oil is remarkably improved by endowing the surface with hydrophobic and oleophilic properties; meanwhile, the chemical and physical stability of the nano metal particles after surface modification treatment is also greatly improved. Therefore, the surface modified nano metal particles have great application potential as lubricating oil additives.
