摘要
研究裂解气相色谱-质谱法定量分析硫化胶中的丁苯橡胶(SBR)成分。结果表明:裂解气相色谱-质谱中的苯乙烯(St)、1,4-丁二烯(BD)和1,2-BD特征峰面积与其含量具有相关性,选择合适的标准曲线进行SBR中St,1,4-BD和1,2-BD的定量,测定结果具有较好的准确性和重复性。
The component of styrene butadiene rubber(SBR)in vulcanizates was determined by using pyrolysis gas chromatography-mass spectrometry.The results showed that,the characteristic peak areas of styrene(St),1,4-butadiene(BD)and 1,2-BD in the pyrolysis gas chromatography-mass spectrometry were correlated with their contents.Therefore,the contents of St,1,4-BD and 1,2-BD in the SBR vulcanizates could be quantitatively determined by comparing their corresponding characteristic peak areas to the standard curves.It was confirmed that the analysis results had good accuracy and repeatability.
