目的 针对目前国内外生物降解塑料产品快速组分分析方法的空白，建立生物降解塑料制品组分分离及鉴定方法。方法 通过采用红外光谱分析(FTIR)、差示量热扫描(DSC)和热重分析(TGA)方法，研究生物降解塑料产品快速组分分析方法。结果 结合FTIR和DSC对树脂组分进行鉴定，结合FTIR和TGA对填料组分进行鉴定，建立了生物降解塑料产品快速组分分析方法。结论 通过本研究可以开展生物降解塑料制品快速组分分析工作，为广大企业提供质量控制技术服务，为监管部门提供监管技术支持，具有重要的现实意义。

The work aims to establish a component separation and identification method of biodegradable plastic products to deal with the blank of rapid component analysis methods of biodegradable plastic products at home and abroad. In this work, a rapid component analysis method of biodegradable plastic products was established through infrared spectroscopy (FTIR), differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA). FTIR and DSC were used to identify resin components, FTIR and TGA were used to identify filler components, and a rapid component analysis method for biodegradable plastic products was established Through this research, rapid component analysis of biodegradable plastic products is carried out. It provides quality control technical services for the majority of enterprises, and provides regulatory technical support for regulatory authorities, which has important practical significance.
