Abstract
Sulfur-free green lubricant additives have received more attention in industrial production. In this study, tri-octyldodecyl phosphonium diisooctyl phosphate （P/P）with UiO-66 composite environmentally friendly lubricating additives were synthesized. The tribological properties of P/P with UiO-66 composite additive in polyalphaolefin-6 (PAO-6) heavy were systematically conducted. The outcomes showed that 1 % P/P@3000 UiO-66 additive had excellent friction reduction and antiwear properties. This was mainly due to the adsorption of oil-soluble P/P on the surface and within the pores of UiO-66, which effectively reduced the tendency of agglomeration of UiO-66 formed a good synergistic effect. Consequently, a favorable and stable balling effect was achieved, thereby preserving the integrity of the lubricant film, resulting in significantly reducing wear from shear and abrasive.
