摘要
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迅速的分析方法。
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.
