摘要:
为探索锦纶化学镀银前处理的最优工艺条件,试验采用钯催化化学镀银的方法,按除油、粗化、敏化、活化顺序逐步处理锦纶纤维,着重探讨锦纶化学镀银前处理工艺中每一步的最佳温度、质量分数和时间,最后对前处理纤维和镀银纤维进行测试和表征。研究表明,最佳前处理工艺条件为除油:温度为40 ℃、质量分数为60 %乙醇溶液和时间为90 min;粗化:温度为40℃、质量分数为15 %盐酸溶液和时间为90min;敏化:温度为40 ℃、质量分数为2 %盐酸及0.6 %氯化亚锡和时间为50min;活化:温度为40 ℃、质量分数为0.05 %氯化钯和时间为50min;采用此工艺的镀银纤维清洗失银率、电阻、强力损失率和镀银率分别为2.5 %、0.4 Ω、17.5 %和28.48%。
Abstract:
In order to explore the optimum pre-treatment conditions for the preparation of electroless silver plat ing of polyamide fibers, the method of electroless silver plating catalyzed by palladium was adopted. P olyamide fibers were treated gradually by oil cleaning, coarsening, sensitization and activation. The optimal temperature, mass fraction and treatment time in each process were investigated. Finally, pre-treated fibers and silver-plated polyamide fibers were tested and characterized. It was found that the optimal pretreatment conditions were as follows: oil cleaning: 60% wt ethanol solution , time 90 minutes, temperature of 40 ℃; coarsening: 40 ℃, 15 % wt hydrochloric acid solution , time 90 minutes; sensitization, 2% wt hydrochloric acid and 0.6 % wt stannous chloride , time 50 minutes , temperature 40 ℃; activation, 40 ℃, 0.05 %wt palladium chloride , time 50 minutes. By using these pre-treatment parameters, the silver loss rate after cleaning , resistance, strength loss and silver plating content were 2.5 %, 0.4 Ω, 17.5 % and 28.48%, respectively.
