聚酯酰亚胺漆包线漆的组分分析

用甲醇醇解法将聚酯酰亚胺降解成小分子化合物。用气质联用仪（GC-MS）对蒸馏出来的溶剂和醇解液进行检测，用红外光谱、原子发射光谱对漆包线漆中的固体成分进行分析，最终得到该种漆包线漆的化学组分。分析结果为：该种聚酯酰亚胺是由对苯二甲酸，乙二醇，偏苯三甲酸和4，4’-二胺基二苯基甲烷合成的；溶剂主要是苯酚，1，2，3-三甲基苯和1-乙基-2，3-二甲基苯组成；助剂为正肽酸丁酯。

Composition Analysis of Polyesterimide Enameled Wire Varnish

Polyesterimide can be converted into small molecular compounds by using methanolysis method.The structure and composition of polyesterimide enameled wire varnish were analyzed by means of gas chromatograph-mass spectroscopy(GC-MS),Fourier-transform infrared spectroscopy(FTIR) and atom emission spectrum.The results showed that polyesterimide was synthesized from terephthalic acid,glycol,trimellitic acid and 4,4′-diaminophenyl methane;the solvents used was a mixture of phenol,1,2,3-trimithyl benzene and 1-ethyl-2,3-dimethyl benzene.The additive used was tetrebuty titanate.
