| 采用十二烷基苯磺酸钠表面活性剂对Accu Lube LB 2000基础油进行改性处理来提高其电导率，获得了适用于静电喷雾润滑的润滑液。通过目标网状法检测改性润滑液的荷电性能，利用四球摩擦磨损试验分析润滑液流量、时间和载荷对静电喷雾润滑摩擦磨损性能的影响。结果表明，表面活性剂溶液体积含量为5%的润滑液具有较稳定的乳化状态，且电导率可达到6.5×10 -5 S/m，能满足静电喷雾润滑的荷电要求；与普通喷雾润滑相比，静电喷雾润滑在不同润滑液流量与载荷下均能获得更好的减摩抗磨性能，尤其是在润滑液流量为5 mL/h和载荷为147 N下作用效果更显著。 |

| The Accu Lube LB 2000 base oil was modified by sodium dodecyl benzene sulfonate to obtain the lubricants suited for the electrostatic spraying lubrication，which had a higher conductivity. The charged performance of conductivity modified lubricants was detected by the method of target meshing, based on which the effect of cutting fluids flow, time and load on the properties of the friction and wear were evaluated by using the four ball friction wear testing experiment. The result showed that the lubricants had a stable emulsified state and met the charged requirements because its conductivity could reach 6.5×10-5 S/m when the concentration of surfactant was at 5%，the better tribological characteristics can be obtained by electrostatic spraying lubrication compared with the normal spraying lubrication at different flows and loads, especially getting more obvious at the flow of 5 mL/h and the load of 147 N. |
