摘　　要：合成了两种含有双黄原酸酯结构的润滑油添加剂,通过核磁共振、红外光谱、元素分析等技术手段表征了产物的结构,测定了合成产物的气味等级、油溶性、铜片腐蚀性能、极压抗磨性,以及试验钢球磨斑表面的元素组成与赋存状态。结果表明:合成的两种黄原酸酯多硫化物均具有良好的油溶性、铜片腐蚀性能和极压抗磨性能,且气味较小;黄原酸酯多硫化物比黄原酸酯二硫化物的极压性能更优;两种黄原酸酯硫化物的极压抗磨性能均优于硫化异丁烯。Two kinds of lubricating oil additives containing bisxanthate structure were synthesized and characterized by nuclear magnetic resonance(NMR),infrared spectroscopy(IR),elemental analysis and other technical means.The odor grade,oil solubility,and copper corrosion properties were tested,and the tribological properties in 150N base oil were investigated by a four-ball friction and wear tester.The elemental composition and chemical state of the wear scar surface were analyzed by X-ray photoelectron spectroscopy(XPS).The results showed that both xanthogen polysulfides had good oil solubility and low odor as lubricant additives,and had good copper corrosion properties and extreme pressure and anti-wear properties.The antiwear properties of xanthate disulfides were better than those of xanthate polysulfides.The extreme pressure properties of xanthate polysulfides were better than those of xanthate disulfides.The extreme pressure and antiwear properties of both additives were better than that of isobutenyl sulfide under the same conditions.
