【摘要】:為更準(zhǔn)確地定量泡沫中的揮發(fā)性有機(jī)化合物(VOC),對標(biāo)準(zhǔn)方法中的頂空分析條件進(jìn)行了優(yōu)化。結(jié)果表明:測定泡沫樣品時(shí),頂空瓶上部空間的大小對結(jié)果影響較大,20 m L頂空瓶0.4~0.5 g的稱樣量最有利于VOC的釋放。座椅泡沫在熱環(huán)境下釋放出了大量的VOC,經(jīng)質(zhì)譜定性為烷烴類、烯烴類、含氧化合物、含氯化合物、含氮化合物、芳香烴類有機(jī)化合物,其中包含氯苯等對人體健康具有高度危害的物質(zhì)。
[Abstract]:In order to more accurately quantify volatile organic compounds (VOCs) in foam, the headspace analysis conditions in the standard method were optimized. The results show that the size of the upper space in the headspace bottle has a great influence on the results when the foam sample is measured. The sample size of 0.4g 0.5 g in the 20ml headspace bottle is the most favorable for the release of VOC. The seat foam released a large number of VOCs in hot environment, which were characterized by mass spectrometry as alkanes, olefins, oxygenated compounds, chlorinated compounds, nitrogenous compounds, aromatic hydrocarbons, organic compounds. It contains chlorobenzene and other substances that are highly harmful to human health.
