Embodiment 1

[0038] Weigh 20g of n-octadecane after melting, disperse with 20g of polyvinylpyrrolidone, 1g of cetearyl polyglucoside and 0.5g of polysorbate-80 in 100g of water, ultrasonicate for 3 hours to form a stable emulsion, add 2g of activated carbon to disperse evenly Finally, add 100mL of 17% sodium sulfate aqueous solution at a rate of 20mL / min, obtain a solid after sedimentation, filtration, and drying, and pulverize into particles of about 30 meshes to obtain the cooling particles. From its DSC curve ( figure 1 ) shows that the phase transition temperature of the cooling particles is 61.6°C, and the phase transition enthalpy is 108 J / g. Weigh 100 mg / piece of cooling particles to prepare a composite filter rod, and wrap it into the rear end of a heat-not-burn cigarette rod to obtain a cigarette sample. see figure 2 , the cigarette sample includes a tobacco segment 1, a hollow filter rod segment 2, a first cellulose acetate filter rod segment 3, a cooling segment 4 and a secon...

Embodiment 2

[0040]Weigh 20g of cetyl alcohol and disperse it with 40g of polyvinylpyrrolidone and 1g of cetyl polyglucoside after melting in 200g of water / ethanol binary solution (the mass ratio of water to ethanol is 1:1). Stir at a speed of 3000 rpm for 12 hours to form a stable emulsion, add 0.5g of expanded graphite to disperse evenly, then add 200mL of a 15% magnesium sulfate aqueous solution at a rate of 10mL / min, and obtain a solid after deposition, filtration, and drying , crushed into particles of about 30 meshes to obtain the cooling particles. Weigh 50 mg / piece of cooling particles to prepare a composite filter rod, and wrap it into the rear end of a heat-not-burn cigarette rod to obtain a cigarette sample. The structure of the cigarette sample in this example is the same as that in Example 1, the only difference is that the cigarette smoke cooling particles provided in this example are added in the cooling section, and the added amount is 50 mg / cigarette.

Embodiment 3

[0042] Weigh 20g of octadecanoic acid and disperse with 10g of polyvinylpyrrolidone, 2g of polysorbate-80 and 0.5g of cetyl glucoside after melting in 100g of water / ethanol binary solution (the mass ratio of water to ethanol is 1:4) , Ultrasound 4 hours to form a stable emulsion, add 0.2g carbon nanotubes to disperse evenly, then add 100mL ammonium sulfate aqueous solution with a concentration of 12% at a rate of 15mL / min, obtain a solid after deposition, filtration, and drying, and crush it into 30 The particles of about mesh are obtained to obtain the cooling particles. Weigh 80 mg / piece of cooling particles to prepare a composite filter rod, and wrap it into the rear end of a heat-not-burn cigarette rod to obtain a cigarette sample. The structure of the cigarette sample in this example is the same as the cigarette sample in Example 1, the only difference is that the cigarette smoke cooling particles provided in this example are added in the cooling section, and the addition...

Abstract

The invention discloses cigarette smoke cooling particles as well as a preparation method and application thereof. The cooling particles comprise an inner core and an outer shell wrapping the inner core, the outer shell comprises a water-soluble polymer and a heat conduction material, and the inner core comprises an organic phase change compound. When high-temperature flue gas flows through the cooling particles, the organic phase change compound can absorb a large amount of heat to reduce the temperature of the flue gas; as the organic phase change compound is coated by the shell, the organicphase change compound is blocked in the shell after absorbing heat and melting, and the shell can prevent the organic phase change compound from overflowing out of the filter stick in the phase change process; the bad smell of the organic phase-change compound can be blocked in the shell, so that the negative influence of the bad smell on the smoke can be avoided; the heat conduction material inthe shell plays a good role in heat conduction, so that the heat of the flue gas can be quickly transferred to the organic phase change compound, the heat conduction capability of the cooling particles can be improved, and the heat absorption efficiency of the organic phase change compound is enhanced.

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 smoke cooling particle and a preparation method and 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. Comp...
