摘要

聚苯硫醚是一种热稳定性好、结晶度高的聚合物。本文总结了聚苯硫醚及其复合材料与常规固体润滑剂的摩擦磨损研究结果,以确定该材料作为固体润滑剂添加剂的适用性。聚合物本身具有很高的摩擦系数。磨损率随着负载和速度的增加而增加。添加固体润滑剂添加剂有助于改善聚合物的摩擦和磨损。添加MoS2- sb2o3和PTFE的复合材料比添加石墨和MoS2石墨的复合材料效果更好。复合材料的磨损率随载荷和转速的增加而增加;但载荷和速度对摩擦的影响很小。

The effect of lubricant additives on friction and wear studies of polyphenylene sulphide
Polyphenylene sulphide is a polymer with good thermal stability and high crystallinity. This paper summarizes the results of friction and wear studies of polyphenylene sulphide and its composites made with conventional solid lubricants to ascertain the suitability of the material as a matrix for solid lubricant additives. The polymer itself has a high coefficient of friction. Wear rate increases with load and speed. Addition of solid lubricant additives helps in improving the friction and wear of the polymer. Composites with MoS2-Sb2O3 and PTFE gave better results than composites made by the addition of graphite and MoS2 graphite. Wear rate of these composites increased with load and speed; but load and speed had little effect on friction.
