| 摘 要： | 针对日益严重的电磁环境污染问题,根据电磁波屏蔽材料对电磁波作用原理,用镍粉和金属纤维作为复合填料,以丙烯酸树脂作粘结剂,按照涂料制备的方法,制备了一种能屏蔽电磁波的复合涂料。将其应用在某有线电视网和电子工作间,进行对比法测试,结果表明:在射频段,该材料将有线电视传输网设备中的干扰场强度降低了40%~50%,在电子工作间上的屏蔽效能达到了30~50dB。

| Abstract: | To solve problem of electromagnetic pollution, a Ni-based composite shielding coating has been prepared based on the electromagnetic shielding principle. Nickel and metal fiber are used as composite fillers, and acrylic resin as binder. The coating is designed for use in some community antenna television (CATV) nets and shielding workshops. The antitheses testing results show that with the material, electromagnetic field strength reduces by 40%~50% in the CATV nets, the shielding effectiveness in shielding workshops reaches 30~50 dB. |
