汽车罩光清漆的固化和降解机理研究(Ⅱ)——用色谱质谱,核磁共振和红外光谱等方法研究罩光清漆的主要成分和结构

Studies on the Mechanism of Solidification and Degradation of Automobile Clear Coating (Ⅱ)——Study on the analysis of the main components and structure of the clear coating by GC/MS, NMR and IR

罩光清漆的色谱质谱 (GC/MS) ,13 C ,1H液体高分辨核磁共振 (NMR)和红外光谱 (IR)等多种方法的综合分析结果表明 ,新型汽车涂料主要是由丙烯酸丁酯 ,丙烯酸 1,2 丙二醇酯等形成的丙烯酸酯共聚物和部分丁氧基化的三聚氰胺甲醛树酯交联剂所组成 ,它们溶解在由多种有机溶剂组成的混合溶剂中 .

Using high resolution 13 C, 1H NMR combined with GC/MS and IR, the comprehensive analysis results of the clear coating show that the new type automobile coating is mainly composed of the copolymer contained butyl acrylates and 1,2 propanediol acrylate and the crosslinker butylated melamine formaldehyde resin, which can be solved in a few kinds of organic solvents.
