新型硅烷偶联剂Si69的TG-DTG分析

The TG DTG Study of New Type Silane Reinforcing Agent Si69

Ｓｉ６９是近年来开发的一种被认为是橡胶助剂中很有发展前途的新型硅烷偶联剂．通过对不同厂家生产的Ｓｉ６９试样进行ＴＧ－ＤＴＧ分析，结合ＧＣ－ＭＳ、Ｘ－ｒａｙＤｉｆｆｒａｃｔｉｏｎｄ的测定，我们得到一系列ＴＧ失重台阶和ＤＴＧ特征峰，并计算出Ｓｉ６９的组分含量，从而判别反应原料的纯度、产品质量的优劣，同时也可以辅证其它化学分析方法．

Si69 is consider of a boundless prospect silane reinforcing agent in the rubber auxiliary,which is developed in recent years.By studying the TG DTG curves of the various Si69,and analysing with GC MS and X ray diffraction,we get a serious characteristic peaks of TG/DTG,calculate the content of the component, and there fore judge the quality of the product.
