采用热重和裂解气相色谱-质谱分析方法剖析轮胎硫化胶

通过裂解气相色谱－质谱（PGC－MS）和热重分析（TGA）等方法，对轮胎不同部位的硫化胶进行了一系列彻底地分析。成功利用PGC－MS确定了多组份橡胶的并用比，另外PGC－MS方法也是一种简单而迅速地测定促进剂和防老剂的方法，这种方法不需对硫化胶进行预处理。用TGA的方法可测定硫化胶的含胶率，碳黑含量，抽出物含量以及灰分含量。在轮胎硫化胶分析中与传统的繁琐的化学分析相比，PGC－MS和TGA被证明是一种准确而导致的分析方法。

Analyzing vulcanized rubber by using TGA and HRPyGC-MS

By using HRPyGC-MS and TGA,a series of thorough analysis of vulcanized rubber taken from different parts of tire were conducted. The HRPyGC-MS was successfully used to determine the blend ratio of multi-component rubber.Also, it is a rapid and simple method to characterization the accelerator and aging retarder, without need to pre-extract the rubber sample. The rubber content, black content extract content and ash content can be determined by TGA. Compared with traditional complicated chemical analysis of tire, the HRPyGC-MS and TGA proved to be accurate and rapid characterization method of vulcanized tire rubber.
