SULFUR-FREE ANTI-WEAR, EXTREME PRESSURE AND ANTI-CORROSION ADDITIVES, AND METHODS FOR PRODUCING AND USES OF THE ADDITIVES

摘要

The present invention provides a sulfur-free composition containing phosphorous atoms, a first metal or metalloid element, and a second metal or metalloid element; and a process for synthesizing it comprising modification of a phosphorous compound using one or more functional groups, and interaction of the modified phosphorous compound with at least two kinds of metal compound and/or metalloid compounds. In specific embodiments, the phosphorous compound is diethylene glycol glycerine ester of triethyl phosphate (DEGGLYTEP) or diethylene glycol of triethyl phosphate (DEGTEP), the functional group is oleic acid, and the metal compounds are titanium alkoxide and aluminium alkoxide. Test results demonstrate that the sulfur-free composition synthesized using the process in the present invention is effective as anti-wear additive, extreme pressure additive and anti-corrosion additive in lubricants, and as anti-corrosion additive in coatings or paints.
