研制了一种锌基合金电镀添加剂EA-2。采用FTIR分析了EA-2的结构，并对其分散能力、覆盖能力、光亮整平能力等性能进行了一系列的测试。结果表明：EA-2能明显提高镀液的稳定性，所得镀层具有平整、光亮、致密、结合力强等优良特性。
Additive EA-2 for zinc based alloy electroplating was synthesized. Properties of EA-2 were determined such as the abilities of leveling, brightening and throwing power. The results show that bath stability is greatly improved by addition of EA-2. Bright, compact and uniform zinc or zinc based alloy deposits with good adhesion are obtained.
