Problems solved by technology

[0006] In this application, only the coating liquid containing the heat-conducting material is directly coated on the substrate, and there is no bonding effect between the raw materials in the coating liquid and the substrate. Therefore, in the subsequent drying operation, after the coating liquid is dried, , the thermally conductive material cannot be firmly bonded to the substrate, but is easily detached, resulting in a problem of poor modification effect

Abstract

The invention relates to the technical field of heat-not-burn cigarettes, in particular to a modification method of a heating cigarette substrate. The method comprises the following steps: dispersinga heat-conducting material in water to obtain a heat-conducting material water solution, and mixing the heat-conducting material water solution with a sodium alginate water solution; adding an acid solution into the mixed solution until the mixed solution becomes a suspension liquid coated with a heat conduction material due to reduction of the solubility of sodium alginate; spraying the suspension on a heated cigarette substrate; and drying to obtain the modified heating cigarette substrate. In the present application, the pH value of the mixed solution is directly changed through the acid solution; the dissolved sodium alginate is separated out; the heat conduction material is gradually coated in the precipitation process; when the sodium alginate coated with the heat conduction materialis in contact with a substrate containing calcium, the sodium alginate and divalent calcium ions are cross-linked to form a chelating structure, so that the sodium alginate coated with the heat conduction material is stably fixed in a substrate system, the operation is simple, and the heat conduction modification of the substrate is uniform and effective.

Description

technical field [0001] The invention relates to the technical field of heat-not-burn cigarettes, in particular to a method for modifying a base sheet of a heated cigarette. Background technique [0002] Electric heating cigarettes are a new type of tobacco product that has gradually emerged in recent years. After the heated cigarette is heated, a large amount of smoke-generating agent and aroma substances with tobacco smell enter the smoke, so that consumers can smoke the smoke without lighting the cigarette. In order to improve the satisfaction of smoke and enable consumers to experience a smoking experience similar to that of conventional cigarettes, it is necessary to increase the smoke volume of heated cigarettes. [0003] In the prior art, a variety of technologies have been developed to modify the heat conduction of heat-not-burn cigarettes to increase the smoke volume, such as a heat-conducting tobacco sheet for cigarettes and its preparation method and application d...
