摘要
利用高温热分解乙酸镍的方法对涤纶织物进行活化,分析了无钯活化工艺对Ni-Fe-P镀覆织物表面电阻的影响,并确定了无钯活化的优化工艺条件;测试了涤纶铁镍镀覆织物的表面电阻,利用XDR对活化层、镀层的晶体结构进行表征,并采用DSC分析活化剂的活化机理。结果表明,优化的活化工艺为:m(乙酸镍)∶m(次亚磷酸钠)∶m(水)=1.5∶2∶30,205℃高温活化5 min,镀覆织物的电阻达到0.55Ω/□,电阻最小可达0.12Ω/□。铁镍镀层均匀性和连续性较好。
Polyester fabric is activated by decomposition of nickel acetate at high temperature. The influ- ences of palladium-free activation process on the surface resistance of Ni-Fe-P coated fabrics are ana- lyzed, and the optimized process conditions for the palladium-free activation are determined. The sur- face resistance of the iron-nickel coated PET fabric is tested. The crystal structure of the activation layer and coating layer are characterized by XDR, and the activation mechanism of the activator is analyzed by DSC. The results show that, the optimal activation process is： m[CH3COO）2Ni] ： rn（NaH2PO2） ： m（H2O）= 1.5：2：30, activation at 205 ℃ for 5 rain. The surface resistance of the coated fabric is 0.55Ω/□, and the minimum resistance is 0.12Ω/□. The Ni-Fe plating and coating of PET fabric is uniform and continuity.
