该文合成了四异丙基硫代过氧二磷酸酯(TPDP)和二异丙基二硫代磷酸硫化氧钼(MoDDP),并在四球机上研究了TPDP的摩擦磨损性能及其对MoDDP抗磨减摩性能的影响.试验结果表明:(l)TPDP具有一定的抗磨作用,但无减摩作用;(2)TPDP对MoDDP的抗磨减摩性能具有协同作用.“,”In this paper, di- (iso -propyl) sulfurized oxymolybdenum dithiophosphate (MoDDP) and tetra (iso propyl) thioperoxy-diphosphate (TPDP) were synthesized and purified. The results show that TPDP is of synergistic effect on MoDDP s reducing wear and friction properities.
