硝基纤维素片化学镀铜工艺研究

Condition Study of Electroless Copper Plating for Nitrocellulose

利用正交实验对硝基纤维素片化学镀铜工艺进行优化,初步确定导电性能优先时最佳工艺条件为c(Cu2+)=5g/L,c(HCHO)=5mL/L,c(NaKC4H4O6.4H2O)=30g/L。对表面金属化的硝基纤维素片进行差热分析以及对镀层进行电阻测定的结果表明,镀层与硝基纤维素片有较好的相容性,镀层有良好的导电性。

The process conditions of electroless copper plating for nitrocellulose are optimized by orthogonal tests. Considering the conductivity of copper layer first, the optimum composition is c（Cu^2＋）=5 g/L, c（HCHO）=5 mL/L, c（NaKC4H4O6·4H2O）=30 g/L. Results indicate that copper layer and nitrocellulose are compatible by DTA method, and conductivity of the copper layer is good through the measurement of its resistance.
