preparation example Construction

[0026] The disclosure provides a method for preparing a cooling section of a heated cigarette containing layered perovskite, including the following steps:

[0027] Step (1): After dissolving the water-soluble polymer material, add layered perovskite, and stir evenly to obtain a mixed solution.

[0028] In order to improve the cooling efficiency, the mass ratio of the water-soluble polymer material and the layered perovskite in step (1) may be (5-7):(3-5).

[0029] In order to improve cooling efficiency, the water-soluble polymer material in step (1) may include at least one of polyvinyl alcohol, modified starch, hydroxypropyl cellulose, carboxymethyl cellulose and gelatin.

[0030] In order to improve cooling efficiency, the layered perovskite in step (1) can include (C 12 h 25 NH 3 ) 2 ZnCl 4 , (C 14 h 29 NH 3 ) 2 ZnCl 4 , (C 16 h 33 NH 3 ) 2 ZnCl 4 , (C 12 h 25 NH 3 ) 2 CoCl 4 , (C 14 h 29 NH 3 ) 2 ZnCl 4 , (C 16 h 33 NH 3 ) 2 CoCl 4 , 0(C 12 ...

Embodiment 1

[0042] 1. Dissolve 50 parts of polyvinyl alcohol 1799 in water, then add 50 parts of (C 12 h 25 NH 3 ) 2 ZnCl 4 After the powder is stirred evenly, a mixed solution with a mass concentration of 20 wt% is formed. Among them, (C 12 h 25 NH 3 ) 2 ZnCl 4 The phase transition temperature is 88°C, and the latent heat of phase transition is 97J / g.

[0043] 2. Coat the mixed solution on the surface of cellulose paper and dry at 80°C to obtain a composite cooling material with a coating thickness of 5um.

[0044] 3. The composite cooling material is embossed, wrapped with paper material, and cut into sections to obtain the cooling section S1 of the heated cigarette, and the embossed width is 1 mm.

[0045] The cooling section S1 is applied to the heated cigarette. When the smoke passes through the cooling section, the temperature of the smoke is reduced by 43°C, the inlet smoke temperature is 46.3°C, and the moisture content of the smoke is reduced, which effectively improves...

Embodiment 2

[0047] 1. Dissolve 65 parts of polyvinyl alcohol 1799 in water, then add 35 parts of (C 16 h 33 NH 3 ) 2 ZnCl 4 After the powder is stirred evenly, a mixed solution with a mass concentration of 15 wt% is formed. Among them, (C 16 h 33 NH 3 ) 2 ZnCl 4 The phase transition temperature is 99°C, and the latent heat of phase transition is 117J / g.

[0048] 2. Coat the mixed solution on the surface of cellulose paper and dry at 75°C to obtain a composite cooling material with a coating thickness of 3.5um.

[0049] 3. Emboss the composite cooling material, gather and wrap it with paper material, and cut into sections to obtain the cooling section S2 of the heated cigarette. The width of the embossing treatment is 1.5 mm.

[0050] The cooling section S2 is applied to the heated cigarette. When the smoke passes through the cooling section, the temperature of the smoke is reduced by 45.6°C, the inlet smoke temperature is 48.2°C, and the moisture content of the smoke is reduced,...

Abstract

The invention discloses a heating cigarette cooling section containing layered perovskite and a preparation method thereof, and the preparation method comprises the following steps: dissolving a water-soluble polymer material, adding the layered perovskite, and uniformly stirring to obtain a mixed solution; coating the surface of cellulose paper with the mixed solution, and drying to obtain a composite cooling material; and allowing the composite cooling material to be subjected to embossing treatment and gathering and wrapping treatment, and cutting into sections to obtain the heating cigarette cooling section. The preparation method of the heating cigarette cooling section containing the layered perovskite is simple in process and easy to apply on a large scale. The cooling section disclosed by the invention can absorb flue gas heat by using the solid-solid phase change behavior of the layered perovskite material, the phase change process is free from leakage, and the negative influence on the flue gas quality is avoided. The water-soluble polymer material can adsorb moisture in the flue gas, the moisture content of the flue gas is reduced, and the burning heat feeling of the inlet flue gas is further reduced.

Description

technical field [0001] The invention relates to the field of manufacturing heated cigarettes, in particular to a cooling section of a heated cigarette containing layered perovskite and a preparation method thereof. Background technique [0002] In recent years, as people pay more attention to smoking and health issues, the sales growth rate of traditional cigarettes has gradually declined, and new tobacco products such as heated cigarettes have received extensive attention and attention. Tobacco companies at home and abroad have increased their research and development efforts on heated cigarettes and launched a variety of heated cigarette products. [0003] Heated cigarettes use low-temperature heating of tobacco components to replace traditional cigarettes to release smoke. Therefore, compared with traditional cigarettes, the harmful substances in the smoke are greatly reduced, but at the same time, the smoke concentration is lower than that of traditional cigarettes. In ...
