| 摘 要： | 采用溶剂萃取,毛细管气相色谱质谱法分离鉴定了TDI聚氨酯塑胶跑道中的有机化合物,用总离子流色谱峰面积归一化方法进行定量。分离出70余个色谱峰,鉴定出53种化合物,占被测总量的94.48%。采用热裂解气相色谱质谱(PyGC/MS)技术分析了TDI聚氨酯塑胶跑道材料,鉴定出35种化合物。实验数据为检测聚氨酯塑胶跑道中有毒有害化学物质及产品质量控制提供了科学依据。

| Abstract: | Organic compounds in toluene diisocyanate (TDI) polyurethane were extracted with acetone and were detected by gas chromatography-mass spectrometry (GC/MS) with capillary column. The quantitative analysis was performed by square peaks obtained with total ion chromatography to normalization. More than seventy peaks were separated, and 53 kinds of compounds were identified, their composition account for 94.48% of the total components. The TDI polyurethane was detected by pyrolysis chromatography-mass spectrometry, 35 kinds of compounds were identified. These data can be applied to the establishment of scientific basis for the detection of harmful chemistries in TDI polyurethane and the control of the products in quality. |
