Method for preventing heat-not-burn fuming material from being affected with damp

The invention discloses a method for enabling a heat-not-burn fuming material not to be affected with damp easily, and belongs to the field of preparation and treatment of heat-not-burn fuming materials. Ethyl cellulose is dispersed in glycerin in a solvent conversion mode and then mixed with a tobacco concentrated solution, a reconstituted tobacco base is coated, glycerin gel is formed in reconstituted tobacco after a solvent is removed in a drying mode, and the heat-not-burn fuming material which is not prone to being affected with damp and high in tensile strength is obtained. According to the preparation method disclosed by the invention, the glycerin adsorbed by the heat-not-burn fuming material taking the paper-making reconstituted tobacco as a base material forms a gel structure, so that the problems that the surface of the heat-not-burn fuming material prepared by directly coating the reconstituted tobacco base with the glycerin is easy to absorb moisture, the physical strength is reduced and the heat
