低温热固型锌铬酸盐转化涂层的研究

Study of the Thermosetting Chromate Conversion Films on Zinc at Low Temperature

研究了热固型锌铬酸盐转化涂层（ＴＣＣＦ）的涂覆液中，加入０．５％～３％（质量百分数）低分子有机酸的反应促进剂，在２００℃固化可得到传统的３００℃固化涂层同样好的防蚀效果，并通过各种分析测得涂层的组成及分布几乎一样的结果。

By adding 0 5%～3% low molecule of organic acid of action promotor to the masking liquid of the thermosetting chromate conversion films on zinc (TCCF),and thermosetting at 200℃, the result is mostly similar to that obtained by thermosetting the coating at 300℃. There is,therefore,the evidence and the possibility to decrease the thermosetting temperature.
