摘　　要：选择两种不同结构的硫化烯烃润滑添加剂(T321和LZ5340),采用四球摩擦磨损试验机考察了其极压和抗磨性能,并对比了二者的抗铜片腐蚀性能。结果表明:两种硫化烯烃均能有效降低基础油的摩擦系数和磨损率,显著提高油品的极压性能;T321的减摩、抗磨以及抗腐蚀性能均优于LZ5340,但其极压性能略差于LZ5340。采用气相-质谱联用仪(GC-MS)、核磁共振波谱仪(NMR)、红外光谱仪(IR)及元素分析仪对添加剂的组成和结构进行分析,研究两种不同类型硫化烯烃的结构和性能之间的构效关系,发现硫化烯烃的有效组分及活性硫含量的差异均对其性能产生影响。Two sulfurized olefin lubricating additives(T321 and LZ5340)with different structures were selected to investigate their extreme pressure and anti-wear properties by using four-ball friction and wear testing machines,and their copper strip corrosion resistance were compared.The results showed that two sulfuried olefins could effectively reduce the friction coefficient and wear rate of the base oil,and significantly improve the extreme pressure performance of the oil.Among them,T321 is superior to LZ5340 in anti-friction,wear resistance and copper strip corrosion resistance,but its extreme pressure performance was slightly worse than that of LZ5340.The composition and structure of the additives were analyzed by infrared spectroscopy(IR),gas chromatography-mass spectrometry(GC-MS),element analyzer and nuclear magnetic resonance spectroscopy(NMR).It was found that the difference of components and active sulfur content had direct influence on the properties of sulfurized olefin.The structure-activity relationship of two sulfurized olefins with different structures was systematically investigated,which could provide guidance for the application of sulfurized olefin lubricating additives.
