Description
Technical Field
The application relates to the technical field of heating non-combustible cigarettes, in particular to a cooling smoke tube.
Background
The highest temperature of the traditional cigarette is near thousand ℃ after lighting, a large amount of chemical substances can be released by high-temperature combustion and pyrolysis of the tobacco, and part of harmful ingredients are accumulated in a human body to a certain extent to cause damage to the health of the human body, so that various substitutes of the traditional cigarette, such as novel tobacco products such as buccal cigarettes, chewing cigarettes, electronic atomized cigarettes, heating non-combustible cigarettes (HnB cigarettes) and the like, are widely appeared in the market. In various novel tobacco products, the HnB cigarettes are similar to the traditional cigarettes in smoking quality and smoking habit, and have good application prospects.
However, when solid, liquid and gas with the same temperature are taken, the sensory temperature of a human body is sequentially increased, so that a consumer can feel a certain burning sensation when smoking HnB cigarettes, and certain damage is caused to the oral viscosity, tracheal mucosa and the like of the consumer, the burning sensation is even higher due to further shortening of the smoke heat exchange time in the later stage of smoking, the smoking quality of the cigarettes is influenced, and the method has great value for cooling research of heating non-burning cigarettes. At present, the cooling measures studied at home and abroad are mainly focused on two aspects of adding cooling materials and designing a cooling structure. The existing method for adding cooling materials is to add cooling materials such as heat absorbing materials, heat storage materials, heat conducting materials and the like into a cigarette filtering section to realize the transfer of smoke heat.
Such a low smoke temperature low resistance PLA tow filter stick and a method for preparing the same are disclosed in the patent document with publication number CN108523216SA, and the method for preparing the same comprises the steps of preparing a phase change material mixture, preparing a phase change material containing a fragrance substance, preparing a slow release fragrance filter stick and the like. According to the application, by combining the addition amount of the phase change material with the low-suction-resistance PLA tow filter stick, the overall suction taste of the cigarette and the heated non-combustible cigarette is improved through triple cooling, and the smoke temperature is reduced. The application uses PLA tow filter stick as carrier, loads phase change material containing aroma substances to achieve cooling effect, wherein the PLA polylactic acid glass transition temperature is about 70 ℃, glass transition can occur at the working temperature of heating cigarettes, melting or fusion bonding phenomenon can occur, and thus flue gas pore channels are blocked, and flue gas can not circulate smoothly.
To solve this problem, an improved cooling filter stick disclosed in the patent document with publication number CN108523220a and a low-temperature cigarette containing the same are disclosed, the cooling filter stick comprises a wrapping material layer and a cooling material sheet, the cooling material sheet is formed by compounding a supporting material layer and a polymer material layer, the cooling material sheet is configured to have a beam column with longitudinal gas passage channels arranged, the supporting material layer covers the surface of the polymer material layer, and the wrapping material layer wraps the cooling material sheet to form the beam column surface, so as to form the cooling filter stick. In this application, the polymer material layer retains its original shape when it is subjected to glass transition, wherein the material of the support material layer includes, but is not limited to, fiber, paper, heat-resistant and air-permeable polymer materials (PPS, PEEK, PI, etc.), metal materials, etc. However, fibers, paper, temperature-resistant and breathable polymer materials and the like have the problems of insufficient supporting strength and easy bending and deformation, and metal materials have the problems of no air holes and large cigarette smoke resistance.
Disclosure of Invention
The application aims to solve the problems and provides a cooling smoke tube.
The technical scheme for solving the problems is that the cooling smoke tube is formed by extruding a master batch into a tube shape and then drying the tube shape, wherein the master batch comprises smoke powder, hydroxypropyl methylcellulose, polyethylene glycol, glycerol and oleic acid.
In the application, a novel smoke tube is provided, the novel smoke tube can be used as a supporting outer layer of a heating cigarette cooling material, and compared with the supporting outer layer such as a fiber paper film in the prior art, the extruded and dried material has better deformation resistance, and the bending strength of the smoke tube is preferably 0.07-1.02Mpa. Compared with the metal support outer layer, the smoke tube has a porous structure, is favorable for absorbing the heat of the smoke in the smoke tube, and can effectively reduce the absorption resistance. Meanwhile, the smoke tube has good phase change property by combining and matching materials in the master batch, and has good cooling effect by matching with the porous structure, so that the smoke tube can be directly used as a cooling section for heating cigarettes without filling cooling materials, the cooling cost for heating the cigarettes is reduced, and a series of problems caused by melting phenomenon of the cooling materials in the working process are avoided.
The principle of the masterbatch with phase change property is that: polyethylene glycol, glycerol and oleic acid are excellent phase-change energy storage materials, but the phase-change process belongs to solid-liquid phase change, and the phase-change energy storage materials become liquid completely when heated to a temperature higher than the phase-change temperature, so that the transportation, storage and application of the phase-change materials are not facilitated. Therefore, the hydroxypropyl methylcellulose is added into the phase-change material, and is used as a polymer containing a large amount of hydroxyl groups, so that a plurality of crosslinking points can be provided for the phase-change material, and the hydroxypropyl methylcellulose is used as a curing agent of the phase-change material, is subjected to physical entanglement and chemical crosslinking with the phase-change material, and can play a role in binding the phase-change material, so that the phase-change material maintains the original shape (solid state) before and after phase change, and the shaped phase-change material is formed.
As the preferable mode of the application, the master batch comprises 70-80wt% of tobacco powder, 4-7wt% of hydroxypropyl methyl cellulose, 1-2 wt% of polyethylene glycol, 2-4 wt% of glycerol, 3-5 wt% of oleic acid and the balance of water.
As a preferred aspect of the present application, the master batch is prepared by: mixing tobacco powder, hydroxypropyl methylcellulose, polyethylene glycol, glycerol, oleic acid and water to obtain a mixture, and performing mud refining treatment on the mixture.
The mud-refining process is commonly used in the ceramic firing process, and means that the particle size of the material particles is reduced by a series of means, and each material is uniformly mixed, including a mode of mechanically refining mud by a mud-refining machine and a mode of manually refining mud.
Preferably, the inner cavity of the smoke tube is provided with a spacer to divide the inner cavity of the smoke tube into a plurality of smoke channels, and the spacer is formed by drying after the master batch is extruded. The structural design of the spacer can further improve the strength of the smoke tube. The surface area of the inner cavity of the smoke tube can be increased through a plurality of smoke channels formed by the spacers, so that more smoke can be contacted with the smoke tube when the smoke tube is used independently, and the cooling effect is improved; the smoke tube is also enabled to provide a plurality of fixing points for the cooling material in the smoke tube when the smoke tube is used for supporting the outer layer of the cooling material, the cooling material can be dispersed, the surface area of the cooling material is improved, and the cooling effect can be improved.
In order to further increase the pore structure on the smoke tube, the hydroxypropyl methylcellulose is preferably modified hydroxypropyl methylcellulose, and the modified hydroxypropyl methylcellulose is a composite material with hydroxypropyl methylcellulose as a shell and polyvinyl chloride as a core. As a preferred aspect of the present application, the modified hydroxypropyl methylcellulose is prepared by the steps of: respectively dissolving hydroxypropyl methylcellulose and polyvinyl chloride in tetrahydrofuran to obtain hydroxypropyl methylcellulose solution and polyvinyl chloride solution; the polyvinyl chloride solution was added dropwise to the hydroxypropyl methylcellulose solution with stirring, and then tetrahydrofuran was removed by heating.
The coefficient of thermal expansion and cold contraction of the polyvinyl chloride is about 80, and the polyvinyl chloride is easy to deform under different temperature conditions. Preferably, when the master batch is extruded into a tube shape, the extrusion temperature is 100-150 ℃; the drying temperature is 20-30deg.C during drying. By utilizing the characteristic, when the master batch is extruded, the polyvinyl chloride is heated to expand to drive the volume of the whole modified hydroxypropyl methylcellulose particles to expand, when the master batch is cooled after extrusion, the shrinkage degree of the polyvinyl chloride is large, and the shrinkage degree of the hydroxypropyl methylcellulose shell is small, so that the hydroxypropyl methylcellulose shell forms a pore structure between polyvinyl chloride cores.
In order to avoid swelling of the polyvinyl chloride closing the pore structure upon suction, it is therefore preferred to remove the polyvinyl chloride after the pore structure has been formed. In the preparation process of the master batch, sodium chloride and urea are added to pug obtained by pug while rolling to obtain a primary material, and the primary material is covered with a polyethylene film and then aged for 24-48 hours to obtain the master batch. Wherein, sodium chloride and urea mainly provide nutrition sources for the growth of stale microorganisms, and as the optimization of the application, the mixing mass ratio of the pug, the sodium chloride and the urea is 1000: (1-5): (1-5).
The aging is to promote the decay of organic matters in the pug to generate organic acid under the action of bacteria, so that the content of humic acid substances is increased and the decomposition of polyvinyl chloride is promoted. Meanwhile, the generated organic acid can be matched with urea added into the generated gas, and holes can be formed on pug in the gas escaping process, so that the hole quantity is improved.
The application has the beneficial effects that:
1. the application provides a cooling material composition and a smoke tube prepared by extrusion drying of the composition, and the smoke tube has good deformation resistance and a multi-cavity structure on a physical level; in the chemical aspect, the smoke tube has good phase change performance, so that the smoke tube can be used as a supporting outer layer of a heating cigarette cooling material, not only can a supporting effect be provided, but also the suction resistance can not be reduced; the heat-insulating material can also be directly used as a cooling section for heating cigarettes, and has good cooling effect.
2. The raw material of the smoke tube is mainly tobacco, and the smoke tube has the body fragrance of tobacco, and can release fragrance in the smoke passing process.
