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。
PPS resin substrate prepared by injection molding instead of the traditional metal substrate, to reduce the eddy current loss of the magnetic clutch isolation sleeve, and add nano-Yimeng clay and glass fiber (GF) to improve the PPS resin The effects of the amount of surface modifier (titanate coupling agent and epoxy resin), the amount and particle size of nanometer clay and the amount of GF added on the mechanical properties of the composites were investigated. The results show that the impact toughness of composites can be obviously improved when adding 5% (mass fraction) (about 64% particle size less than 100 nm) particles modified by 2% epoxy resin, and the notch Impact strength increased by 60.2%; on the basis of adding 30% of GF, significantly enhanced the tensile strength and flexural strength of nano-Yimeng clay-GF-PPS composites. Compared with the eddy current loss of different substrate isolating sleeves, compared with the metal substrate isolating sleeves, the composite isolating sleeves have very low eddy current loss, which improves the transmission efficiency while ensuring the mechanical properties of the isolating sleeves.
