Description
Technical Field
The invention relates to the technical field of heating non-combustible cigarettes, in particular to a porous material functional tube, a preparation method thereof and an aerosol generating product containing the porous material functional tube.
Background
With consumer importance on health problems and the increasing demand for personalized experience of cigarette products, the tobacco industry is continuously responding to consumer demand upgrading, and various smoking articles with tar and harm reducing effects are developed. Wherein, the heating cigarette is different from the traditional cigarette product in the cigarette heating mode, so that the heating cigarette can provide healthier smoking experience while meeting the sensory requirements of consumers on the cigarette product.
Existing integrated aerosol-generating articles include an outer tube, an aerosol-generating substrate packed within the outer tube, and other functional units for cooling, flavoring or fuming functions.
The aerosol generating substrate of the existing integrated aerosol generating product is usually prepared by mixing tobacco powder or tobacco particles, a fuming agent and a binder into slurry, then obtaining a tobacco core strip through an extrusion or molding mode, and then cutting into a plurality of tobacco core rods, which has the problems that in order to ensure that the tobacco core rods at the cutting position are not deformed and not collapsed in the cutting process, the tobacco core rods need to have certain hardness, but the tobacco core rods are extremely fragile due to the overlarge hardness, and the tobacco core rods are easy to break in the filling and packaging process or the use process, so the two difficult problems of excessively small hardness, difficult cutting and excessively large hardness and easy breaking exist. In addition, the use of a large amount of binder during the formation of the smoke generating material powder or tobacco particles is required, and the binder becomes hard after curing, which is also responsible for the excessive hardness of the overall tobacco rod.
The perfuming of the filter unit is usually achieved by adding the fragranced beads inside. There are still numerous problems with this approach: firstly, the adding form of the flavoring substances is limited in selection range, and only the flavoring substances which are easy to form explosion beads can be added. Secondly, consumers realize flavoring by pinching the explosion beads during sucking, but as the explosion beads are instantaneously pinched and exploded, the flavoring substances in the interior are instantaneously released during pinching and explosion, so that the flavor is thick in the early stage of sucking, and the flavoring substances remain in the later stage of sucking, so that the quality of the flavor is inconsistent before and after sucking.
It is therefore desirable to develop new forms of filter unit perfuming means, as well as to solve the problem of the unitary aerosol-generating substrate rod being too stiff and to ensure that the cut does not collapse or deform.
The present invention has been made to solve the above problems.
Disclosure of Invention
The invention provides a porous material functional tube which comprises a porous material, a flavoring substance and/or a fuming substance, supporting fibers and a binder.
Preferably, the porous material comprises activated carbon, ceramic molecular sieve-based inorganic material, or polymer-based organic material, or plant natural porous material.
Preferably, the flavouring substance comprises menthol, ionone, ethyl maltol, vanillin, rose absolute flavour or a tobacco extract or a nicotine salt.
Preferably, the smoking material comprises one or more of glycerol or propylene glycol.
Preferably, the pipe wall thickness of the porous material functional pipe is 0.8mm-1.5mm.
Preferably, the support fibers are selected from plant fibers including one or more of the pulp fibers commonly used in the art, such as fluff pulp fibers, or wood pulp fibers, wherein the wood pulp fibers may be selected from commonly used wood pulp fibers such as birch, poplar, or pine.
Preferably, the porous material functional tube is configured as a tube body with one or more axial airflow channels. When the hollow pipe body is a common hollow pipe body, the hollow pipe body is provided with one axial airflow channel, and when the hollow pipe body is internally provided with a structure with a cross-shaped or Y-shaped cross section, the hollow pipe body is provided with a plurality of axial airflow channels.
The second aspect of the invention provides a preparation method of the porous material functional tube according to the first aspect of the invention, comprising the following steps:
(1) The porous material firstly adsorbs the flavoring substances and/or fuming substances;
(2) Mixing the porous material adsorbed with the flavoring substances and/or the fuming substances with the support fibers, then adding the adhesive into the mixture, and mixing to obtain mixed slurry;
(3) The mixed slurry is molded by extrusion or molding to obtain the porous material functional tube.
Preferably, in step (1), the porous material is in the form of a powder having a mesh size of 80-500 mesh, wherein the loading of the flavouring and/or fuming substance is 40-80% by weight of the porous material; in the step (2), the binder comprises a water-soluble binder, and the length of the support fiber mixed with the porous material is 0.5mm to 5mm.
The length of the plant fiber added to the porous material functional tube is defined herein, and is not the length of the plant fiber raw material, because the plant fiber used in the market at present is usually agglomerated for storage and transportation, and the process of defibration is needed when the plant fiber is used, that is, the agglomerated plant fiber needs to be loosened, and the process can adopt the following two methods: firstly, soaking the plant fibers agglomerated into water, after the plant fibers are untwisted, carrying out wet grinding until the required fiber length is obtained, and at the moment, the untwisted plant fibers are dehydrated again because the plant fibers mixed with the porous material cannot contain a large amount of water. And secondly, directly dry-grinding the agglomerated plant fibers until the required fiber length is obtained, and mixing the agglomerated plant fibers with a porous material.
Preferably, the addition amount of the supporting fiber is 5-10% of the total mass of the mixed slurry, and the addition amount of the binder is 50-70% of the total mass of the mixed slurry.
A third aspect of the invention relates to an aerosol-generating article comprising a functional tube of porous material according to the first aspect of the invention for use in a filter rod and/or a tobacco rod of an aerosol-generating article.
The filter rod herein refers to a filter rod unit other than a plug rod, and when the porous material functional tube is used for a filter rod of an aerosol-generating article, the filter rod of the aerosol-generating article may have an acetate tow filter segment, an empty tube segment, or the like, in addition to the porous material functional tube of the present invention.
The aerosol-generating article comprising the tobacco rod of the present invention is particularly suitable for heating modes other than central heating, such as circumferential heating, air flow heating, etc., because the tobacco rod with a central passage used for central heating in the prior art is reduced in volume due to loss of a fuming agent, etc., after being heated, the tobacco rod is contracted inwards, which causes the sucked tobacco rod to be stuck to a heating rod, and is difficult to clean. The present invention recognizes this problem, and uses the rod for heating cigarettes other than central heating, such as circumferential heating and airflow heating.
Compared with the prior art, the invention has the following beneficial effects:
1. the porous material functional tube takes the porous material as a main body, and the porous material is used for adsorbing the flavoring substances or the fuming substances to realize the flavoring or fuming effect, so that the flavoring substances or the fuming substances can be added independently or simultaneously for the filtering section, and the fuming substances or simultaneously for the fuming section.
The advantage of its separate addition of the flavouring substance for the filter stage is that: the method expands the selection range and form of the flavoring substances, and is not limited to the flavoring by the explosion beads, and any flavoring substances can be adsorbed in the porous material. In addition, the flavoring substances are adsorbed into the porous material, so that the flavoring substances in the porous material are slowly released in the sucking process, the slow release of the flavoring substances can be realized by the flavoring in the form, and the consistency of the quality of the fragrance before and after the sucking is ensured. Furthermore, on the basis, the flavoring substances and the smoke substances can be simultaneously added for the filtering section, and the smoke substances in the filtering section can supplement the smoke quantity in the later period of suction.
The advantage of adding the fuming substance alone for the fuming section is that: the porous material can adsorb a large amount of the smoking agent, thereby achieving the supply of the amount of smoke without the need to add tobacco dust or tobacco. Further, on this basis, can also add aroma-enhancing substance and fuming substance simultaneously and be used for the section of fuming, owing to the section of fuming temperature is higher, so introduce aroma-enhancing substance into the section of fuming more in favor of the release of aroma-enhancing substance to improve aroma effect, in addition, the characteristic flavor flue gas of different flavor types can be realized to different aroma-enhancing substances, and add aroma-enhancing substance and fuming substance at the section of fuming, can make characteristic flavor and flue gas mix more even, the aroma harmony is better.
2. The porous material functional tube takes the supporting fiber as the molding auxiliary material, and the addition of the supporting fiber has the following advantages: (1) The support fiber has higher sugar content, and the addition of the support fiber can produce an adhesive effect on the porous material, so that the use amount of the adhesive is reduced, the porous material is ensured to be adhered into a rod, and the problem that the functional tube of the porous material becomes hard and brittle after the adhesive is solidified is solved. (2) The supporting fiber can play a role in supporting the porous material functional tube and prevent the porous material from collapsing and deforming when the porous material flavored long strip is cut into the porous material functional tube. (3) The support fiber is odorless and the suction does not affect the smoke being sucked.
3. Because the porous material functional tube is integrally formed, when the porous material functional tube is used as a smoke generating section, the porous material functional tube can be directly compounded with other elements together with forming paper without using cigarette paper or forming paper, or can be filled into the paper tube together. When the porous material functional tube is used as a filter rod, forming paper can be omitted. When the porous material function tube is used as a plug rod, the cigarette paper can be omitted.
4. The porous material functional pipe has the structure of a pipe body with one or more axial airflow channels. In order to increase the flow area of smoke, the conventional smoke core rod is generally provided with a groove at the periphery as an axial channel, but the invention discovers that when the smoke core rod is compounded with other units by a compounding machine, the smoke core rod is picked up by a roller of the compounding machine through suction, and the contact area between a smoke suction port of the roller and the smoke core rod is too small due to the groove at the periphery, so that the smoke core rod is difficult to suck, and the problem of falling frequently occurs. Therefore, the cigarette core section structure is in a circular tube shape with a plurality of axial channels in the center, and the periphery of the cigarette core section structure is not provided with axial grooves, so that the contact area between the air suction inlet of the roller and the cigarette core rod is increased, and the air suction inlet of the roller can be ensured to more stably suck the cigarette core rod.
5. The porous material functional rod has higher adsorption capacity for flavoring substances and fuming substances, so that the porous material functional rod has higher fragrance carrying capacity compared with reconstituted tobacco sheets or acetate fiber tows.
