Latest Patents
Ojima's latest patents include advancements in metal lubricants containing a bridge complex. These lubricants are designed to quickly and easily form a lubricating layer on metal surfaces before plastic processing. The primary lubricating agent features a bridge complex with at least two central metal atoms, where a first multidentate ligand connects these atoms. Additionally, a second multidentate ligand is bound to one of the central metal atoms, providing coordination with metal atoms while maintaining partial coordination. Furthermore, a third multidentate ligand may include sulfur atoms that are coordinated to the central metal atom.
Another significant patent involves water-based lubricants that contain sulfur as a coordinating atom. This aqueous lubricant forms effective lubricating films on metal surfaces without the use of oil. It is created by suspending a metal chelate compound in water, which has a polydentate or multidentate chelate ligand with sulfur as a coordinating atom. When applied, these lubricants produce metal sulfides that enhance lubrication through tribo-chemical reactions.
