摘　　要：采用综合热分析仪测试纳米铜、镍、锡和SiO2粉以及超细蛇纹石粉的差热分析曲线,研究了常用固体润滑添加剂的热稳定性,并用平氏毛细管黏度法研究了含不同质量分数纳米金属Cu-Ni-Sn粉、纳米SiO2粉和超细蛇纹石粉对基础油黏度及黏度指数的影响。结果表明:纳米铜、镍、锡和SiO2粉以及超细蛇纹石粉等几种固体润滑添加剂的热学性质比较稳定,在200℃以前不发生氧化现象,其对基础油的黏度和黏度指数没有影响,具备作为润滑油添加剂的条件。The thermal stability nickel, tin, SiO2 nano-particles and of common solid lubricating additives was ultra-fine serpentine powders which tested studied based on the DTA curves of copper, by synthesis thermo-analysis instrument. The influence of different mass fraction of Cu-Ni-Sn nano-particles, SiO2 nano-particles, ultra-fine serpentine powders on base oil viscosity and viscosity index（VI） was discussed by Ping＇ s capillary viscometer. The results show that copper, nickel, tin,SiO2 nano-particles and ultra-fine serpentine powders have relatively stable thermal properties, there is no oxidation phenomenon occured below 200℃ and they have no effect on the viscosity and viscosity index of base oil, and can be used as lubricant additives.
