红外光谱法/差示扫描量热法鉴别氯醚橡胶类型

摘要

用红外光谱法（FTIR）和差示扫描量热法（DSC）对氯醚橡胶生胶和硫化胶进行表征。结果表明，采用FTIR法，根据Beer-Lambert定律，可以准确鉴别氯醚橡胶生胶类型；采用DSC法测定的氯醚橡胶生胶和硫化胶Tg基本相同，可以以此作为鉴别氯醚橡胶的依据。%The raw rubber and vulcanizate of epichlorohydrin rubber (ECO) were characterized by infrared spectroscopy (FTIR) and differential scanning calorimetry (DSC). The results showed that FTIR could be used for accurate identiifcation of ECO type based on the Beer-Lambert law. DSC results showed that the Tg of raw ECO rubber and vulcanized ECO rubber were basically the same, which could also be used for identiifcation of epichlorohydrin rubber.
