摘要:
Reaction products of hydrocarbylsuccinic anhydrides, polyamines and triazoles, as exemplified by XRT 2143A, have been found to be effective rust/corrosion inhibiting, thermal stabilizing and superior dispersant additives with excellent cleanliness feature for fuels and lubricants. Enhanced antioxidancy is also observed upon boration of these reaction products.
摘要:
The invention concerns an additive package for a lubricating fluid or grease containing an effective amount of a phosphorus-containing antiwear additive, the improvement comprising the absence of primary, secondary, tertiary, cyclic low molecular weight aliphatic amines with a carbon number of C30 or less.
摘要:
The invention relates to compositions suitable as additive packages for lubricants and other functional fluids, the composition comprising sulfur-containing extreme pressure components, phosphorus-containing anti-wear additives, a triazole-containing species. A preferred use is in industrial gear oils. In embodiments, enhance protection in the areas of bearing wear and micropitting are obtained.
