合成了具有特定表面张力的阳离子型聚丙烯酸酯和胺改性的环氧树脂 ,并制备成复合电泳涂料 ,通过电泳涂装制得复合涂膜。傅立叶红外光谱 (FT- IR)和 X光电子能谱 (XPS)的分析结果表明 ,涂膜为复合组成。聚丙烯酸酯主要分布在表层 ,环氧树脂主要分布在底层。而且两种树脂表面张力相差越大 ,复合涂膜的分层程度越显著 Synthesis of a specific surface tension of cationic polyacrylate and amine modified epoxy resin, and prepared into a composite electrophoretic coating, obtained by electrophoretic coating composite coating. Fourier transform infrared spectroscopy (FT-IR) and X-ray photoelectron spectroscopy (XPS) analysis showed that the coating composition for the composite. Polyacrylate is mainly distributed in the surface layer, the epoxy resin is mainly distributed in the bottom. And the greater the difference between the two kinds of resin surface tension, the more significant the degree of delamination of the composite coating
