Heating cigarette core material and preparation method thereof

The invention provides a heating cigarette core material and a preparation method thereof. According to the preparation method of the heating cigarette core material, the fiber papermaking sheet base is adopted as a carrier, the two-stage transfer coating and six-section tunnel type continuous low-temperature drying technology is applied, and the prepared heating cigarette core material has the advantages of being large in tensile strength, good in on-machine performance, high in coating rate, large in loading capacity, large in fuming amount, obvious in characteristic fragrance, good in stability and the like; the prepared heating cigarette core material can remarkably improve the smoking thickness and satisfaction and improve the smoking sensory quality. The tensile strength of the prepared heating cigarette core material can reach 400 N/m or above, the on-machine adaptability is good, and the requirement for quantitative production is met. 本发明提供一种加热卷烟芯材及其制备方法。本发明的加热卷烟芯材制备方法采用纤维抄造片基为载体，运用两级转移涂布、六段隧道式连续低温干燥技
