一种无氰镀银光亮剂及其电镀液制造技术

本发明专利技术涉及一种无氰镀银光亮剂及其电镀液，该种无氰镀银光亮剂以水为溶剂，主要成分为十二烷基二苯磺酸钠10-20g/L，β-萘酚聚氧乙烯醚15-30g/L，HEDTA0.8-2g/L，磷酸二氢钾0.5-3g/L，尿素5-15g/L，聚乙二醇3-18g/L，含硫杂环化合物40-80g/L，含氮羧酸5-15g/L。本发明专利技术的光亮剂不含氰化物，镀层镜面光亮，能达到氰化镀银同等效果，经过镀层性能测试发现，经过本无氰光亮镀银镀液电镀过的镀层不易变色，脆性小，附着力好，能满足不同应用方面对镀层的需求。

Non cyanide silver plating brightener and electroplating liquid thereof

The invention relates to a cyanide free silver plating brightener and electroplating solution, the cyanide free silver plating brightener with water as solvent, the main composition is twelve with two alkyl benzene sulfonic acid sodium 10-20g/L, beta naphthol polyoxyethylene ether 15-30g/L, HEDTA0.8-2g/L, 0.5-3g/L and 5-15g/L of urea, potassium dihydrogen phosphate, polyethylene glycol 3-18g/L, sulfur heterocyclic compounds containing nitrogen 40-80g/L carboxylic acid 5-15g/L. The invention of the cyanide free plating brightener, mirror light, can achieve the same effect of cyanide silver plating, after plating test showed that, after the non cyanide bright silver plating bath plating coating had no discoloration, brittleness, good adhesion, can meet the needs of different applications of the plating layer.
