摘　　要：颗粒型加热卷烟烟芯段与加热元件匹配时,需在烟支中添加阻隔固件以避免烟芯材料掉落,文章利用聚乙烯醇(PVA)制备得到可生物降解的加热卷烟用阻隔固件材料。采用熔融共混法,添加不同比例的改性黄麻纤维制备得到聚乙烯醇复合材料,并研究黄麻纤维对聚乙烯醇热力学性能的影响。研究结果显示:改性后的黄麻纤维与PVA基体的相容性明显提升,并促进了复合材料的耐热性能与导热性能的提升;改性黄麻纤维的加入改善了PVA复合材料的耐热性能,维卡软化温度明显提升;改性黄麻纤维的添加提升了PVA/黄麻纤维复合材料的热稳定性。甘油溶胀的PVA/改性黄麻复合材料是生物基多功能热安全阻隔固件的优秀备选材料之一。When the core segment of granular heating cigarette is matched with the heating element, barrier firmware should be added to the cigarette to avoid the dropping of the core material. In this paper, biodegradable barrier firmware for heating cigarette was prepared by using polyvinyl alcohol(PVA). Polyvinyl alcohol(PVA) composites were prepared by melting blending method and adding different proportions of modified jute fiber, and the effect of jute fiber on the thermodynamic properties of PVA was studied. The results showed that the compatibility between the modified jute fiber and PVA matrix was improved obviously, and the heat-resistance and thermal conductivity of the composites were improved. The addition of modified jute fiber improves the heat resistance of PVA composite, and the vicat softening temperature is obviously increased. The addition of modified jute fiber improves the thermal stability of PVA/jute fiber composites. Glycerol swelling PVA/modified jute composite is one of the excellent candidate materials for bio-based multi-function thermal safety barrier firmware.
