▎ 摘  要

NOVELTY - Preparing conjugated heat transfer modified cellulose thermally conductive adhesive, comprises (i) mixing the conjugated thermally conductive material with the soluble cellulose, and blending and granulating to obtain the modified cellulose after esterification; (ii) adding modified cellulose into a solvent, mixing, and concentrating to obtain the obtained product. USE - The adhesive is used to prepare heat-conducting enhanced tobacco sheet, tobacco or heated tobacco products. ADVANTAGE - The conjugated heat-transfer modified cellulose heat-conducting glue has high heat conducting performance, and effectively blocks the risk of the transfer of the heat conductive material to the human body during the smoking process of the tobacco. The covalent bond of the material is fixed, and the high thermal conductivity of the conjugated thermal conductive material is used to form a functional cellulose material with high thermal conductivity, which can be used to improve the thermal conductivity of tobacco and its cigarette products. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: conjugated heat transfer modified cellulose thermally conductive adhesive; heat-conducting enhanced tobacco sheet, formed by cutting the heat-conducting enhanced tobacco sheet, or formed by spraying and curing the conjugated heat transfer modified cellulose heat-conducting adhesive on the surface of the shredded tobacco; and heating cigarette with enhanced heat conduction, comprises shredded tobacco with enhanced heat conduction.
