摘　　要：在聚丙烯(PP)原料中添加除味剂LDV1040,通过熔融加工工艺制得改性PP颗粒。采用扫描电子显微镜(SEM)观察改性前后PP颗粒的微观形貌,对改性前后的PP颗粒进行傅里叶变换红外光谱(FTIR)分析,并测试不同LDV1040质量分数对PP颗粒气味等级、挥发性有机化合物(VOC)含量、甲醛含量及热稳定性的影响。研究结果表明:在PP原料中添加除味剂LDV1040,可制得低气味、热稳定性好的PP颗粒。Modified polypropylene(PP)particles were obtained through melting process by adding deodorizer LDV1040 into PP.Scanning electron microscope(SEM)was used to observe the microstructure of PP particles before and after modification.Then,the PP particles were analyzed by Fourier transform infrared spectroscopy(FTIR),and the effects of different LDV1040 mass fractions on the odor level,volatile organic compounds(VOC)content,formaldehyde content and thermal stability of PP particles were tested.The results showed that by adding deodorizer LDV1040 to PP,modified PP particles with low-odor and good thermal stability could be prepared.
