摘　　要：采用注塑成型制备的聚苯硫醚(PPS)树脂基材代替传统的金属基材,以降低磁力联轴器隔离套的涡流损耗,并添加纳米伊蒙黏土和玻璃纤维(GF)来提高PPS树脂的力学性能,探究了表面改性剂(钛酸酯偶联剂和环氧树脂)用量、纳米伊蒙黏土添加量和粒径以及GF添加量等对复合材料力学性能的影响。结果表明:当添加5%(质量分数)(粒径小于100 nm颗粒约为64%)、并经2%环氧树脂改性的纳米伊蒙黏土时,可明显改善复合材料冲击韧性,且缺口冲击强度提高了60.2%;在此基础上再加入30%的GF,明显增强了纳米伊蒙黏土–GF–PPS复合材料的拉伸强度和弯曲强度。对比了不同基材隔离套的涡流损耗,与金属基材隔离套相比,复合材料隔离套具有极低涡流损耗,在保证隔离套力学性能的同时,提高了传递效率。In order to reduce the eddy-current loss of isolation sleeve in magnetic coupling, a composite material with polyphenylene sulfide （PPS） resin and nano-sized illtite-smectite clay （I/S clay） and glass fiber was prepared via injection moulding instead of the conventional metal base material. The effects of modifier type （i.e., titanate coupling agent and epoxy resin） and content, content and particle size of the illtite-smectite clay, content of glass fiber on the mechanical properties of the composite material were investigated. The results show that the notched impact strength is increased by 60.2% after added 5% （in mass fraction） of nano-sized I/S clay with particle size less than 100 nm of 64%, and modified by 2% epoxy resin. Furthermore, the tensile strength and flexural strength of the composite material can be enhanced when glass fiber of 30% is added in the composite material. According to the eddy-current loss measured and simulated results, the nano-sized I/S clay-GF-PPS composite material for an isolation sleeve in magnetic coupling has a rather low eddy-current loss and a superior mechanical properties.
