摘要: 采用实时直接分析-高分辨质谱-独立成分分析(DART-HRMS-ICA)法对改性聚硫橡胶样品的热解行为进行研究.首先进行DART检测条件的优化,然后在该优化条件下,对在不同离子源温度条件下得到的2个独立成分(IC-1和IC-2)进行ICA解析.结果表明,当样品传输速度为0.5 mm/s,离子源栅极电压为150 V时,样品的离子采集效果和离子化的信号强度都较好;样品在200℃以下时较为稳定;IC-1在200℃时开始受热分解,在350℃时可持续分解为以IC-2为表征的其他较小分子量组成的特征组分.改性聚硫橡胶在常温环境中具有很好的热稳定性,能够广泛应用于工业生产.

Abstract: The thermal decomposition behavior of modified polysulfide rubber (MPR) was investigated by direct analysis in real time-high resolution mass spectrometry (DART-HRMS) independent component analysis (ICA). The DART conditions were optimized, and then two independent component (IC-1 and IC-2) obtained with different ion source temperature under the optimal conditions were processed by ICA. The results showed that ion collection effect of the sample and ionization signal strength were better when sample transmission speed was 0.5 mm/s and ion source grid voltage was 150 V. The sample had good stability when the temperature was lower than 200℃. IC-1 began to decompose at 200℃, and the sample could be decomposed as IC-2 which could characterize the components with lower molecular weights at 350℃. Modified polysulfide rubber had good thermal stability at room temperature environment, and could be widely used in industrial production.
