Abstract

Tall oleic acid diethanolamide was synthesized from refined tall oil and diethanolamine as main raw material mixed, and the tribological performance of its waterbased lubricant additive produced by mixing with molar ratio of 1∶1 was studied. The behaviors of extreme pressure and anti-attrition for different concentrations of additives were examined by testing on a four-ball tester, and the pH value and rust protection performance were measured according to GB-T6144-2010. Results show that water base extreme pressure performance can be improved by using tall oleic acid diethanolamide, and PB value is up to 1020 N for 5% lubricant, the higher concentration, the better the antifriction performance. pH meets the requirements of national standard, and rust protection reaches to A level as concentration up to 3%.
