双氰胺改性偶氮二甲酰胺在聚丙烯中的发泡特性研究

Foaming Behavior of Dicyandiamide Modified AC in Polypropytene Matrix

以偶氮二甲酰胺 (AC)为参照 ,通过TG、DSC、动态粘弹性分析和发泡体系熔体回弹高度差测试 ,研究双氰胺改性AC发泡剂的分解温度、放热量及其在各种聚丙烯基体中的发泡特性。

By contrast with azodicarbonamide (AC), the decomposition temperature and exotherm of dicyandiamide modified AC blowing agent and its foaming behavior in different polypropylene matrixes were studied by means of TG and DSC and test of dynamic viscoelastivity and difference of melt rebound height.
