AI Technical Summary
Technical Problem
Ionic liquids have low solubility in non-polar base oils and are potentially corrosive, which affects their application in automotive transmission fluids.
Method used
An ionic liquid friction-reducing and anti-wear additive with a specific structure is prepared through an ion exchange reaction. It combines antioxidants, detergents, and corrosion inhibitors to form a protective film that provides multi-point and multi-mode synergistic lubrication, thereby improving solubility and anti-wear performance.
Benefits of technology
It functions as a friction modifier under low loads and as an extreme pressure anti-wear agent under high loads, improving lubrication performance and service life, while being environmentally friendly and free of sulfur, phosphorus, and halogens.
