The intermediate dibutyldithiocarbamate sodium was synthesized by dibutyl amine,carbon bisulfide and sodium hydroxide.With this intermediate,the chlorinated paraffin-52（T302） was modified through nucleophilic substitution.The target product was characterized by IR,thermogravimetric analysis and elemental analysis.Four ball wear tester,multi-specimen test system,rotary bomb oxidation method and pressurized differential scanning calorimeter were employed to evaluate the tribological and antioxidative performances of the synthesized additive in base oil HVI 150.The results show that the additive T302G has good lubricity and auxiliary antioxidative fuction.
