摘　　要：对4种环保塑解剂DBD(A,B,C,D)进行成分剖析及塑解效果评价研究。结果表明:环保塑解剂DBD在气相色谱-质谱联用仪分析过程中主要分解产物为2-苯基苯并噻唑和2-巯基-N-苯基苯甲酰胺两种;环保塑解剂A和D的有机部分是单一有效成分DBD;环保塑解剂B和C则是由熔点高低不同的物理有机增塑剂成分与主体成分DBD复合而成;4种环保塑解剂塑解效果由高到低顺序为:环保塑解剂C、环保塑解剂B、环保塑解剂A、环保塑解剂D。The composition analysis and plasticizing effect evaluation of four environmental-friendly plasticizer DBD(A,B,C,D) were studied. The results showed that the main decomposition products of the environmental-friendly plasticizer DBD in the analysis result of gas chromatography-mass spectrometry were 2-phenylbenzothiazole and 2-mercapto-N-phenylbenzamide. The organic part of the environmental-friendly plasticizers A and D was a single effective component DBD. On the other hand, the environmental-friendly plasticizers B and C were composed of physical organic plasticizer components with different melting points besides main component DBD. The order of the plasticizing effect of those four environmental-friendly plasticizer from high to low was:C,B,A and D.
