Embodiment 1

[0035] Weigh 70g of polylactic acid and feed it into a screw extruder to melt, extrude and granulate to obtain 1-2mm cooling granules. Utilize this cooling particle to prepare cooling nozzle stick ( figure 1 ), the circumference of the cigarette is 24.0mm, the length of the tobacco section 1 is 15mm, the length of the polylactic acid particle section 2 is 12mm, and the length of the solid filter tip 3 is 8mm. Smoking in ISO mode was carried out on a single-hole smoking machine (puffing time was 2 s, puffing interval was 58 s, and the puffing volume was 35 mL per puff), and the smoke temperature of the filter was detected online by a cigarette gas phase temperature detector. for 47 o C, 10% shrinkage.

Embodiment 2

[0037] Take by weighing 70g polylactic acid, 5g graphene, 8g calcium carbonate whisker, 12g calcium nitrate hydrate and 5g aluminum powder (diameter is 0.5mm) and mix evenly, send into the screw extruder and melt and extrude granulation, obtain 1~ 2mm cooling particles. Utilize this cooling particle to prepare cooling nozzle stick ( figure 1 ), the circumference of the cigarette is 23.0mm, the length of the tobacco section 1 is 14mm, the length of the modified polylactic acid particle cooling section 5 is 15mm, and the length of the solid filter tip 3 is 8mm. Smoking in ISO mode was carried out on a single-hole smoking machine (puffing time was 2 s, puffing interval was 58 s, and the puffing volume was 35 mL per puff), and the smoke temperature of the filter was detected online by a cigarette gas phase temperature detector. The test results show that compared with Example 1, the composite filter with phase change material has a significant effect on reducing the smoke tempera...

Embodiment 3

[0039] Weigh 65g of polylactic acid, 7g of montmorillonite, 11g of carbon fiber, 10g of sodium sulfate hydrate, and 7g of copper powder, mix them evenly, and send them into a screw extruder for melt extrusion and granulation to obtain a cooling line with a diameter of 0.5mm. The cooling wires are bundled to obtain the cooling nozzle stick ( figure 2), the circumference of the cigarette is 23.0mm, the length of the tobacco section 1 is 14mm, the length of the modified polymer fiber cooling section 5 is 15mm, and the length of the solid filter tip 3 is 8mm. Smoking in ISO mode was carried out on a single-hole smoking machine (puffing time was 2 s, puffing interval was 58 s, and the puffing volume was 35 mL per puff), and the temperature of filter smoke was detected online by a cigarette gas temperature detector. The test results show that compared with Example 1, the composite filter with phase change material has a significant effect on reducing the smoke temperature, from 47°...

Abstract

The invention discloses a heat-not-burn cigarette smoke cooling material and its application, wherein the heat-not-burn cigarette smoke cooling material is obtained by screw extrusion processing of the following raw materials according to the mass percentage: 50-75% polymer, layered nano 5-15% of materials, 4-15% of fibrous nano-materials, 5-10% of phase-change materials, and 3-10% of metal powders. Due to the addition of layered nanomaterials and fibrous nanomaterials, the cigarette smoke cooling material of the present invention exhibits high heat-resistant shrinkage, which avoids the defect of polylactic acid cooling materials being heat-shrinkable; the addition of exogenous phase-change materials makes it It has a better cooling effect; in addition, the cooling material has a low interception rate of smoke and basically does not affect the smoking experience.

Description

technical field [0001] The invention relates to a heat-not-burn cigarette smoke cooling material and an application thereof, belonging to the field of novel tobacco products. Background technique [0002] A large number of studies have shown that nicotine and most flavor components can be released from tobacco and transferred to smoke at a relatively low temperature (250-500oC). Excessively high temperatures will not increase the types and types of harmful components in smoke. content, it will also convert the aroma components into harmful substances. Therefore, if the temperature of the cigarette is lowered below 500oC, which is the so-called "tobacco is heated but not burned", various harmful components of the smoke can be greatly reduced, while the impact on the aroma components is relatively small, and some aroma components may even be affected by heat. Solution decreases and increases. [0003] Based on this idea, a new concept tobacco product of "tobacco heating but ...
