The cure and degradation processes of the clear coating were studied by 13 C CP/MAS and GHPD/MAS NMR.
利用13 C交叉极化 (CP)和门控高功率去偶 (GHPD)二个脉冲序列的魔角旋转核磁共振 (MASNMR)技术表征了汽车罩光清漆的固化和降解过程 ,研究结果表明涂料在固化后形成的丙烯酸酯 三聚氰胺交联 ,经较长时间的紫外线曝晒 ,逐步降解 ,生成少量的三聚氰胺 三聚氰胺交联和丙烯酸酯 丙烯酸酯交
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.
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 。
The main components of the clear coating imported were obtained using high resolution 13 C NMR, 1H NMR combined with GC/MS, IR and GPC.
利用液体高分辨 13 C、1H核磁共振 (NMR) ,结合色谱质谱 (GC/ MS)、红外光谱 (IR)和凝胶色谱 (GPC)等多种手段分析了由国外进口的罩光清漆中的漆料和溶剂的主要成分 ,并对漆料中的高分子共聚物和交联剂的配比进行了定量估算 ,进而分析了它们在溶液中可能存在的结构。
