Embodiment 1

[0032] Weigh 20g of polyethylene glycol 4000 and 30g of polyacrylic acid and disperse them in 50g of water, ultrasonicate for 3 hours to form a uniform system, cast into a film, volatilize the solvent (water) and dry to obtain a cooling composite film. figure 1 Be the scanning electron microscope picture (SEM) of the cross-section of the cooling composite thin film of the present embodiment, figure 2 Be the SEM figure of the cooling composite film surface of the present embodiment, by figure 1 and figure 2 It can be seen that the phase change component (polyethylene glycol) has been uniformly immobilized in the cooling composite film substrate. The cooling composite film is rolled into a sheet with wrinkles, and the sheet is made into a cooling filter rod through a paper nozzle rod forming process, and the cooling filter rod is cut into cooling sections with a length of 15 mm. The cooling section is placed between the tobacco section and the cellulose acetate filter sectio...

Embodiment 2

[0034] Weigh 20g of palmitic alcohol and 10g of polyethylene oxide and disperse them in 100g of water / ethanol binary solution (the mass ratio of water to ethanol is 1:1), stir mechanically at a stirring speed of 1000 rpm for 6 hours to form a uniform system, and cast Form a film, volatilize the solvent (water and ethanol) and dry to obtain a cooling composite film. image 3 Be the SEM figure of the cooling composite film surface of the present embodiment, by image 3 It can be seen that the phase change material (palmityl alcohol) has been uniformly immobilized in the cooling composite film substrate. The cooling composite film is rolled into a sheet with wrinkles, and the sheet is made into a cooling filter rod through a paper nozzle rod forming process, and the cooling filter rod is cut into cooling sections with a length of 15 mm. The cooling section is placed between the tobacco section and the cellulose acetate filter section of the heat-not-burn cigarette to obtain a ci...

Embodiment 3

[0036] The mixed solution that takes by weighing 10g stearic acid and certain volume is formed by 5g formaldehyde, 8g phenol, 1g sodium hydroxide, 1.2g resorcinol, 0.13g petroleum sodium sulfonate is dispersed in 50g water / ethanol binary solution ( The mass ratio of water to ethanol is 4:1), and the volume ratio of the mixed solution to the water / ethanol binary solution is 2:1. After ultrasonically forming a stable emulsion, it is heated to 75°C for 4 hours, cooled to room temperature, and then cast into a film, the solvents (water and ethanol) were evaporated and dried to obtain a cooling composite film. The cooling composite film is rolled into a sheet with wrinkles, and the sheet is made into a cooling filter rod through a paper nozzle rod forming process, and the cooling filter rod is cut into cooling sections with a length of 15 mm. The cooling section is placed between the tobacco section and the cellulose acetate filter section of the heat-not-burn cigarette to obtain a...

Abstract

The invention discloses a cigarette cooling composite film and application thereof. The cooling composite film comprises a film carrier and a phase change component immobilized on the film carrier, the film carrier comprises a water-soluble polymer, an alcohol-soluble polymer, or a polymer polymerized in situ in an aqueous solution. Through the immobilization effect of the film carrier, the overflow phenomenon of the phase change component in the phase change process can be inhibited. The cooling composite film is applied to heating non-combustible cigarettes, the problem of poor smoking feeling caused by leakage of phase change components is avoided while the temperature of mainstream smoke is reduced, the smoking quality of products is improved, and the smoking experience of consumers isimproved.

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 composite film and its application. 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 cigarett...
