摘要
对比了多种防锡变色剂的效果，发现月桂胺是一种优良的防锡变色剂。月桂胺处理镀锡层的最佳条件为：月桂胺２．５ｇ／Ｌ；ｐＨ＝８；７０℃；１０ｍｉｎ。ＸＰＳ和ＡＥＳ分析结果表明，月桂胺中的氮与锡表面发生配位作用并在锡表面形成耐蚀性保护膜。从膜的ＡＥＳ元素深度分布曲线的恒定区求得配合物膜的组成（Ａ．Ｃ．％）为：Ｏ３９．０％；Ｓｎ４８．７％；Ｎ７．９％；Ｃ４．４％。
By comparison of the antitarnishing effects of various agents, the laurylamine was found to be an excellent antitaranishing agent for tinplate. The optimum conditions of treatment were laurylamine 2.5g/L; pH=8.70℃; 10min. The results of XPS and AES analyses showed that on tinplate surface an anticorrosive coordination compound film of laurylamine was formed, and N atoms in laurylamine molecule were coordinated with Sn (II). The relative atomic percent contents (A.C.%) of the film calculated at the constat elemental composition section of the AES profile curves were O 39.0%; Sn 48.7%; N 7.9%; C 4.4%.
