Embodiment 1

[0042] Weigh 10g of polyvinyl alcohol 1788 (polyvinyl alcohol with a degree of polymerization of 1700 and a degree of alcoholysis of 88%) and add it to 100g of deionized water to prepare an aqueous solution of polyvinyl alcohol with a mass fraction of 10%, mechanically stirring at 95°C After the polyvinyl alcohol is completely dissolved, add 10 g of polyethylene glycol 4000, mechanically stir for 2 hours to form a uniform dispersion system, and stand at 60 ° C for 30 minutes for defoaming. Then pour the uniformly dispersed system into a stainless steel mold, freeze at -20°C for 12 hours, and thaw at room temperature for 6 hours. This freeze-thaw is a cycle. After 3 cycles, the polyvinyl alcohol cross-linked gel system is obtained. The polyvinyl alcohol cross-linked gel system is lyophilized to remove ionized water, and finally crushed into particles of about 20 meshes to obtain cigarette cooling gel particles.

[0046] Weigh 10g of polyvinyl alcohol 1799 (polyvinyl alcohol with a degree of polymerization of 1700 and a degree of alcoholysis of 99%) and add it to 190g of deionized water to prepare an aqueous solution of polyvinyl alcohol with a mass fraction of 5%, mechanically stirring at 95°C After the polyvinyl alcohol is completely dissolved, add 10g of polyethylene glycol 2000 and 10g of erythritol, mechanically stir for 2 hours to form a uniform dispersion system, and stand at 60°C for 30 minutes for defoaming. Then pour the uniformly dispersed system into a stainless steel mold, freeze at -20°C for 12 hours, and thaw at room temperature for 6 hours. This freeze-thaw is a cycle. After 5 cycles, the polyvinyl alcohol cross-linked gel system is obtained. The polyvinyl alcohol cross-linked gel body is freeze-dried to remove water, and finally crushed into particles of about 20 meshes to obtain cigarette cooling gel particles.

Abstract

The invention discloses cigarette cooling gel particles and application thereof. The cigarette cooling gel particles comprise a base material and a water-soluble phase-change material, the water-soluble phase-change material is immobilized on the base material, the base material comprises polyvinyl alcohol, and the water-soluble phase-change material comprises one or more of polyethylene glycol, sugar alcohol, sodium sulfate decahydrate, calcium chloride hexahydrate and potassium chloride. The water-soluble phase-change material is immobilized in the base material, so that the problem of leakage of the phase-change material in the phase conversion process in the prior art is solved. Besides, the polyvinyl alcohol in the base material can be converted from a glassy state to a high-elastic state in a smoke temperature interval and can absorb a certain amount of heat, so that the overall heat absorption capacity of the cigarette cooling gel particles is further improved.

Description

technical field [0001] The invention relates to the technical field of cigarettes, in particular to heat-not-burn tobacco products, and more specifically, to a cigarette cooling gel particle and an application thereof. Background technique [0002] In recent years, new tobacco products have achieved rapid development. Among them, heat-not-burn tobacco products have a good development prospect because their smoking habits are closest to traditional cigarette products. The heat-not-burn tobacco technology uses an external heating element to heat the tobacco substrate at a temperature of 200-400°C, and the shredded tobacco or sheet produces distillation and pyrolysis products in a non-combustible state. However, due to the large area of ​​the heating package and the single way of heat dissipation, the inlet temperature of the high-temperature atomized flue gas is relatively high, which brings problems of burning sensation and unpleasant aftertaste. Compared with traditional ci...
