Problems solved by technology

There are also some so-called electric heating cigarettes suitable for regular size cigarettes (about 8mm in diameter, 50-60mm in length) on the market, but in fact there are only heating devices and no special cigarettes. The smoke produced is often harsh and difficult to swallow

Embodiment 1～5

[0049] According to the formula and process in Table 1, mix guar gum, plant fiber, and metal powder, and then carry out wet copying molding to obtain a heat-conducting sheet base. In embodiment 1~5, the metal powder that selects is copper powder, and density ρ is 8.9g / m 3 , with a particle size of 8 μm.

[0051]

[0052]

[0053] At the same time, the electron microscope scanning is carried out on the thermal conductive sheet, and it can be seen from the electron microscope lens that the copper powder particles in the thermal conductive sheet base are closely combined with the fibers through the bonding of the adhesive; the copper powder particles are in contact with each other, which can form a local The heat conduction chains, the heat conduction chains are connected and penetrate each other to form a heat conduction network that runs through the entire heat conduction sheet, so that the heat conduction performance of the heat conduction sheet is signif...

Embodiment 6～9

[0054] The preparation of embodiment 6~9 heat-conducting material

[0055] According to the formula and process in Table 2, 10 grams of binder, 100 grams of plant fiber, ρ×A×10 -6 Gram of metal powder (where ρ is the density of metal powder, the unit is g / m 3 , A is the conversion factor, and the value of A is 1.5) Carry out wet copying molding to obtain a heat-conducting sheet base.

[0057]

Embodiment 10

[0060] The mensuration of embodiment 10 thermal conductivity

[0061] The thermal conductivity of the heat-conducting sheet bases of Examples 1-9, Comparative Examples 1, 2 and 3, the paper base of Comparative Example 4, and several commercially available cigarette sheets for non-burning cigarettes were measured.

[0062] The thermal conductivity is calculated according to the following formula:

[0063] TC=α×ρ×C

[0064] In the formula, TC is the thermal conductivity (w m-1 K-1), α is the thermal diffusivity (m2 s-1), and ρ is the density (kg m -3 ), C is the specific heat capacity (J·kg-1·K-1).

[0065] Measurement of thermal diffusivity α: measured with LFA457 analyzer at 30°C;

[0066] Density ρ: determined by the weight and size of the sample;

[0067] Specific heat capacity C: Measured with DSC 200F3 at 30°C.

Abstract

The invention discloses a heat-not-burn cigarette cut tobacco module and a preparation method thereof. The heat-not-burn cigarette cut tobacco module comprises a heat conductive cut tobacco structurecoiling around the central axis of the cut tobacco module, wherein the heat conductive cut tobacco structure comprises a heat conductive piece base and a tobacco sheet alternately; the heat conductivepiece base is prepared from raw materials including plant fiber, metal powder and an adhesive by wet papermaking and overpressure treatment. The heat-not-burn cigarette cut tobacco module combines the heat conductive piece base and the tobacco sheet, heat can be transmitted to the tobacco sheet more quickly and more uniformly by means of high heat conductivity of the heat conductive piece base, and aroma concentration and aroma fullness of a heat-not-burn cigarette during smoking are improved obviously, The scheme is applicable to both central heating type heat-not-burn cigarettes and peripheral heating type heat-not-burn cigarettes.

Description

technical field [0001] The invention relates to the field of cigarette technology, in particular to a shredded tobacco module of a heat-not-burn cigarette and a preparation method thereof. Background technique [0002] When a cigarette is burned, it will produce a lot of harmful substances, such as: tar, carbon monoxide, etc., which will endanger the health of smokers and the surrounding people in severe cases. Therefore, how to reduce the release of harmful substances in cigarettes is an urgent problem. [0003] Heat-not-burn cigarettes (such as electric heating cigarettes and charcoal heating cigarettes), because the cut tobacco is heated at a lower temperature, the release of harmful substances is significantly lower than that of conventional cigarettes; and this low-temperature cigarette has less sidestream smoke, which is harmful to the environment. The impact is also small. Therefore, this heat-not-burn low-temperature cigarette is sought after by more and more consum...
