Hydroxyalkyl dithiocarbamates, their borated esters and lubricants, functional fluids, greases and aqueous compositions containing the same

摘要

This invention relates to a lubricating composition comprising a major amount of an oil of lubricating viscosity and (A) a minor amount of at least one hydroxyalkyl dithiocarbamate or at least one borate thereof, wherein the dithiocarbamate is derived from an amine other than an alkyl or alkenylsuccinimide. In another aspect the invention relates to a lubricating composition comprising a major amount of an oil of lubricating viscosity, a hydroxyalkyl dithiocarbamate or a borate thereof, and (B) at least one sulfur compound or (C) at least one phosphorus or boron antiwear or extreme pressure agent. The invention also relates to greases, functional fluids and aqueous fluids containing the hydroxyalkyl dithiocarbamates and borates thereof. The lubricants and fluids have improved antiwear and extreme pressure properties including providing improved antiscuff protection.
