摘　　要：利用红外-热重联用技术研究了淀粉基塑料,并与聚丙烯树脂、马铃薯淀粉作了全面比较,确定了淀粉基塑料在TG曲线中的失重率和分解温度以及在红外光谱图热分解产物的特征吸收峰。结果表明,淀粉基塑料热解主要分为两步,两者失重互不影响,确定其材质为聚丙烯树脂与马铃薯淀粉,最后计算出淀粉基塑料中淀粉含量大约为50. 6%。Fourier transform infrared spectroscopy( FTIR)-thermogravimetry( TG) combined technology was used to study starchbased plastics,and a comprehensive comparison with polypropylene and potato starch was performed to determine the weight loss rate and decomposition temperature of starch-based plastics in the TG curves and the characteristics of thermal decomposition products in the infrared spectrum. The absorption peak shows that the pyrolysis of starch-based plastics is mainly divided into two steps,and the weight loss of the two could not affect each other. The materials are polypropylene and potato starch. Finally,the starch content in starch-based plastics is calculated to be about 50. 6%.
