Description
Technical Field
The invention relates to the field of heating non-combustible cigarettes, in particular to a cigarette core material of a heating non-combustible cigarette, a preparation method of the cigarette core material, the heating non-combustible cigarette and a heating non-combustible system.
Background
The heating non-combustible cigarette core material has no appearance of flake, filament, particle and other forms, and for the flake and filament cigarette core material, in order to ensure the sufficient heating by the heater, no matter ordered arrangement or disordered arrangement, the arrangement is tight, the contact surface is increased, so as to benefit the heat conduction, thus space can not be provided for the gathering of the smoke, and the smoke quantity of the consumer in the mouth is less, and the smoke concentration is low. The granular cigarette core material has the problems that although gaps are formed among granules, cigarette fragrance substances on the surface are easy to volatilize by heating, and the inside is difficult to overflow due to the binding of the outer surface.
In view of this, the present application is specifically made.
Disclosure of Invention
The invention aims to provide a cigarette core material for heating a non-combustible cigarette, a preparation method thereof, the non-combustible cigarette and a non-combustible heating system, so as to solve the problems.
In order to achieve the above purpose, the invention adopts the following technical scheme:
a cigarette core material for heating non-combustible cigarettes is spherical and has a porous structure.

preferably, the outer diameter of the core material is 0.6-2 mm;
preferably, the specific surface area of the core material is 0.25-0.4m2/g；
Preferably, the porosity of the core material is 31-72%.
Compared with pores of 10 microns or even larger, the micropores with the pore size range have larger cigarette fragrance loading capacity, and can better realize the slow release of cigarette fragrance (the cigarette fragrance is loaded on the surface and inside the porous macroporous particles, and as the heater continuously heats, cigarette fragrance substances on the surface volatilize firstly, and then volatilize in the pores, so that the slow release is realized). Too large a pore size can result in a reduced fragrance loading, which in turn reduces the smoking experience.
Alternatively, the pore diameter of the pores in the porous structure may be any value between 100nm, 200nm, 300nm, 400nm, 500nm, 600nm, 700nm, 800nm, 900nm, 1000nm, and 100-1000 nm; the outer diameter of the core material may be any value between 0.6mm, 0.8mm, 1mm, 1.2mm, 1.4mm, 1.6mm, 1.8mm, 2mm and 0.6-2 mm; the specific surface area of the core material may be 0.25m2/g、0.30m2/g、0.35m2/g、0.40m2G and 0.25-0.4m2Any value between/g; the porosity of the core material may be any value between 31%, 35%, 40%, 45%, 50%, 55%, 60%, 65%, 70%, 72%, and 31-72%.
A preparation method of the cigarette core material of the non-burning cigarette comprises the following steps:

Detailed Description
The terms as used herein:
"prepared from … …" is synonymous with "comprising". The terms "comprises," "comprising," "includes," "including," "has," "having," "contains," "containing," or any other variation thereof, as used herein, are intended to cover a non-exclusive inclusion. For example, a composition, process, method, article, or apparatus that comprises a list of elements is not necessarily limited to only those elements but may include other elements not expressly listed or inherent to such composition, process, method, article, or apparatus.
The conjunction "consisting of … …" excludes any unspecified elements, steps or components. If used in a claim, the phrase is intended to claim as closed, meaning that it does not contain materials other than those described, except for the conventional impurities associated therewith. When the phrase "consisting of … …" appears in a clause of the subject matter of the claims rather than immediately after the subject matter, it defines only the elements described in the clause; other elements are not excluded from the claims as a whole.
When an amount, concentration, or other value or parameter is expressed as a range, preferred range, or as a range of upper preferable values and lower preferable values, this is to be understood as specifically disclosing all ranges formed from any pair of any upper range limit or preferred value and any lower range limit or preferred value, regardless of whether ranges are separately disclosed. For example, when the range "1 ~ 5" is disclosed, the ranges described should be construed to include the ranges "1 ~ 4", "1 ~ 3", "1 ~ 2 and 4 ~ 5", "1 ~ 3 and 5", and the like. When a range of values is described herein, unless otherwise stated, the range is intended to include the endpoints thereof and all integers and fractions within the range.
In these examples, the parts and percentages are by mass unless otherwise indicated.
"part by mass" means a basic unit of measure indicating a mass ratio of a plurality of components, and 1 part may represent any unit mass, for example, 1g or 2.689 g. If we say that the part by mass of the component A is a part by mass and the part by mass of the component B is B part by mass, the ratio of the part by mass of the component A to the part by mass of the component B is a: b. alternatively, the mass of the A component is aK and the mass of the B component is bK (K is an arbitrary number, and represents a multiple factor). It is unmistakable that, unlike the parts by mass, the sum of the parts by mass of all the components is not limited to 100 parts.
"and/or" is used to indicate that one or both of the illustrated conditions may occur, e.g., a and/or B includes (a and B) and (a or B).
Embodiments of the present invention will be described in detail below with reference to specific examples, but those skilled in the art will appreciate that the following examples are only illustrative of the present invention and should not be construed as limiting the scope of the present invention. The examples, in which specific conditions are not specified, were conducted under conventional conditions or conditions recommended by the manufacturer. The reagents or apparatus used are not indicated by the manufacturer, and are all commercially available.
