摘　　要：以涤纶织物为基材,对其化学镀铜后再化学镀镍–磷合金镀层。探讨了化学镀Ni–P合金工艺各因素对镀金属织物导电性和增重率的影响,通过正交试验优化了化学镀Ni–P合金工艺,并对镀Cu/Ni–P合金织物的结合牢度、耐蚀性和电磁屏蔽效能进行了表征。结果表明,涤纶基铜层表面化学镀Ni–P合金镀层的最优配方和工艺为:NiS O4·6H2O 26 g/L,Na H2PO2·H2O 24 g/L,Na3C6H5O730 g/L,Na2B4O7·10H2O 6 g/L,温度80°C,p H 11,时间25 min。最优工艺下制备的镀铜/镍–磷织物的结合强度高,耐腐蚀性和电磁屏蔽性能良好。Electroless copper plating followed by electroless nickel-phosphorous plating was conducted on polyester fabrics. The influences of different factors of electroless NiP alloy plating on the conductivity and weight gain rate of metal-plated fabric were discussed. The process parameters of electroless NiP plating were optimized by orthogonal test. The adhesion strength, corrosion resistance, and electromagnetic shielding property of Cu/Ni-P alloy-plated fabric were characterized. The optimal bath composition and operation conditions of electroless NiP alloy plating on copper-plated polyester substrate were obtained as follows： NiSOa 6H20 26 g/L, NaH2PO2 H20 24 g/L, Na3C6H5O7 30 g/L, Na2B4OT-10H20 6 g/L, temperature 80 ℃, pH 11, and time 25 min. The CufNi-P-plated fabric features strong adhesion strength and good corrosion resistance and electromagnetic shielding property.
