Multifunctional Lubricant Additive Improves Lubrication and Antioxidation Properties of Tung Oil

It is of considerable significance to develop efficient and environmentally friendly machinery lubricant additives because the increasing depletion petrochemical resources severe environmental problems. Herein, we proposed a facile strategy synthesize multifunctional vegetable oil-based via lignin derivative vanillin coupled amine diethyl phosphite produce lubricating additive with both extreme pressure antioxidant properties. Compared pure tung oil, performance oil significantly improved after adding additives. Adding 1.0 wt% reduced friction wear coefficient volume, oxidation induction time was much longer than oil.
