| 摘 要： | 采用气相色谱-质谱法(GC-MS)对3种软聚氯乙(烯S-PVC)试样的挥发性有机物进行了测试,分析了产生气味的物质。结果表明:试样产生的挥发性有机物为烃类化合物、醇和醛、酯等羰基化合物,产生气味的化合物主要是羰基化合物;添加抗氧剂可阻止增塑剂和其他烃类的氧化,减少S-PVC塑料气味的产生。

| Abstract: | The volatile organic compounds in 3 kinds of soft polyvinyl chloride(S-PVC) samples were tested by gas chromatography-mass spectrometer(GC-MS).The materials that give out odour were analyzed.The results show that the volatile organic compounds in the samples are hydrocarbon,alcohol and carbonyl compounds(such as aldehyde and ester),and the compounds that give out odour are mainly carbonyl compounds;the addition of antioxidant can inhibit the oxidization of plasticizers and other hydrocarbons,and then decrease the odour in S-PVC. |
