Tall oleic acid diethanolamide was synthesized from refined tall oil and diethanolamine as main raw material mixed, and the tribological performance of its waterbased 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%.
