采用不锈钢纤维( SSF)填充丙烯腈-丁二烯-苯乙烯塑料制备导电工程塑料,并测试材料的物理和电磁屏蔽吸收性能.结果表明,SSF质量分数为15％时,能较好地兼顾材料的物理性能与加工难度,且在强电磁源主要频段有20 dB以上的屏蔽效能.低频磁场屏蔽效能测试结果表明,材料对低频磁场影响甚微,不影响地雷磁引信正常工作.该材料有助于提高磁引信地雷在高功率电磁环境下的生存能力.%A new kinds of conductive engineering material was prepared, by using stainless steel fibers ( SSF ) to fill acrylonitrile-butadiene-styrenecopolymer, and physical properties and electromagnetic shielding and absorptive capabilities of the new materials were tested. The results showed that when the mass fraction of SSF was 15%, the new material was better balanced between the physical properties and the difficulty of processing. The electromagnetic shielding effect was more than 20 dB in main frequency band of high power microwave sources. The test of shielding effect in low frequency magnetic field showed that the new material had few influence on low frequency magnetic field and magnetic fuze of landmine could normally work. The new material could promote the viability of landmine with magnetic fuze in high power electromagnetic environment.
