摘　　要：制备了一种镍磷非晶态合金电磁屏蔽材料,并对制备工艺及其性能进行了初步的研究与探讨,选择了一条较为成功的工艺流程。选用已化学镀铜导电涤纶织物,经过电镀处理,得到稳定、光亮的非晶态镍磷镀层。利用正交试验方法,研究了镀液组成、温度、时间、pH值等对镀层的K/S值与电阻值的影响,优选出了最高K/S值和最低电阻值的工艺条件,分析了各因素对电沉积过程的影响。得出工艺条件:硫酸镍250g/L、氯化镍55g/L、次亚磷酸钠70g/L、硼酸45g/L、时间10min、温度65℃、pH=2.0。实验表明,此电镀镍磷非晶态合金柔性电磁屏蔽材料具有良好的导电性能及耐磨擦、耐腐蚀性能。An electromagnetic shielding material was made by electroplating amorphous nickel-phosphorous alloy on a fabric, and the preparation process was studied. Stable bright amorphous nickel-phosphorous alloy coating was obtained by electroplating on copper-coated terylene. The effects of electrolyte composition, temperature, time, and pH on the K/S value and resistance of the deposit were studied by orthogonal test, and the process parameters for optimum K/S value and Resistance were determined, which were as follows：NiSO4 250 g/L, NiCl2 55 g/L, NaHPO2 70 g/L, H3BO3 45 g/L, 10 min, 65 ℃, pH =2. 0. The experiments showed that this soft electromagnetic shielding fabric had a fine corrosion and abrasion resistance property.
