摘要
采用自制导电涤纶织物和棉织物,通过在交联剂中均匀分散导电粉末制得屏蔽涂料,采用涂敷方法得到电磁波屏蔽织物。讨论了导电粒子种类与质量分数对涂层表面比电阻、涂层的屏蔽性能等的影响。结果表明:采用三明治型涂敷方式,每层涂层中导电粉末的质量分数分别为银粉70%、石墨60%,涂层的总厚度40～60μm,所得屏蔽织物的屏蔽效能最优,在30～1500MHz内平均达30dB,织物的手感保持良好,有工业化前景。
The conductive shielding coating was prepared by coating of conductive polyester fabrics and cotton fabrics with conductive powder. The effects of conductive powder types and quality content on the surface specific resistance and coating shielding properties of the conductive shielding coating were studied. The results showed that using sandwich-type coating method, the typical conductive powder scores for the quality of 70 % Ag, graphite 60 %, coating thickness of 40-60 μm, the shielding fabric obtained had optimum shielding effective, 30 dB within an average of 30-1 500 MHz, fabric had good hand and indusrialization prospects.
