Tribological and Oxidation Properties Study of a Kind of Sodium Sulfonate-Modified Nano Carbonate Sodium
The tribological properties of a high base value sodium sulfonate-modified nano carbonate sodium as lubricating oil additive were introduced in this paper, and its antioxidant collaboration property with ashless antioxidant was evaluation by using pressure differential scanning calorimetry(PDSC). The results show that the product possesses good tribological properties, thermal stability, and a good synergistic antioxidation effect with ashless antioxidant, and mainly to increase oxidation free energy of base oil.
