采用模压烧结工艺制备了不同质量分数的聚苯硫醚(PPS)和二硫化钼(MoS2)填充聚四氟乙烯(PTFE)密封材料,并探讨了PPS含量对PPS/MoS2/PTFE密封材料的维氏硬度、压缩回弹性能等的影响。结果表明,PPS含量的不同对PPS/MoS2/PTFE密封材料的性能具有显著影响。随着PPS填充量的增加,PPS/MoS2/PTFE密封材料的维氏硬度逐渐增大,压缩率逐渐降低,回弹率逐渐升高。
The polytetrafluoroethylene (PTFE) sealant filled with polyphenylene sulfide (PPS) and molybdenum disulfide (MoS2) was prepared by molding and sintering process, and the influence of PPS content on the microstructure and mechanical properties of PPS / MoS2 / PTFE sealant Hardness, compression resilience and other effects. The results show that the different PPS content has a significant effect on the performance of PPS / MoS2 / PTFE sealing materials. With the increase of PPS loading, the Vickers hardness of PPS / MoS2 / PTFE sealing material gradually increases, the compressibility decreases and the rebound rate gradually increases.
