AC发泡剂分解活化机理的红外光谱分析

Study on Infrared Spectra of AC Blowing Agent Activation Mechanism

利用红外光谱对氧化锌、硬脂酸锌与偶氮二甲酰胺(AC)配位进行分析。结果表明:AC经配位处理后,其C═O伸缩振动吸收峰、C—N═伸缩振动吸收峰、N═N伸缩振动吸收峰发生偏移。AC与锌化合物发生了配位,使其热分解更容易进行。

The coordination between zinc oxide or zinc stearate and AC（azodicarbonamide） was analyzed by use of infrared spectroscopy.The results show that： after AC is coordination treated,the C═O stretching vibration absorption peak,C-N═ stretching vibration absorption peak and N═N stretching vibration absorption peak shift.The coordination between AC and zinc compounds makes thermal decomposition of AC become easier.
