TSSC发泡剂分解活化机理的红外光谱分析

Study on infrared spectra of TSSC blowing agent activation mechanism

利用红外光谱技术对不同物质如氧化锌、硬脂酸锌与TSSC(对甲苯磺酰胺基脲)配位进行分析。结果表明:与未处理TSSC相比,其CO伸缩振动、C—NH伸缩振动、—SO2伸缩振动、S—N伸缩振动以及N—H面内变形振动吸收峰发生偏移;TSSC与锌化合物发生了配位,使得TSSC热分解更容易。

Coordination could be analyzed between different substances such as zinc oxide or zinc stearate and TSSC （p-Toluenesulfonyl semicarbazide） by use of Infrared spectroscopy. The results showed that, compared with untreated TSSC, C =O stretching vibration, C-NH stretching vibration ,-S02 stretching vibration, S-N stretching vibration, N-H in-plane deformation vibration absorption peak shifted after coordination process. The coordination between TSSC and zinc compounds made it easier for thermal decomposition of TSSC.
