Abstract
The invention discloses a carbonaceous heat source integrating self-extinguishing and anti-falloff functions. The carbonaceous heat source is of a cylindrical structure which is 10-20mm long; one end of the carbonaceous heat source is freely hung, called a free section, and the other end is fixed, called a fixed section; the ratio of the length of the fixed section to the length of the entire carbonaceous heat source is 1 to 4; and an expansive layer, which is 500-1500 [micro]m thick and is equal to the fixed section in length, covers the surface of the fixed section. The carbonaceous heat source disclosed by the invention is applicable to low-temperature heated cigarettes; and the carbonaceous heat source is capable of avoiding harm to human bodies in the case of the invasion of glass fibers when the cigarettes are covered by glass fibers and like heat-insulating materials and is also capable of avoiding the problem that rest parts of the cigarettes are ignited by the burning carbonaceous heat source which is to be burnt out.
Description
One, technical field
The present invention relates to a kind of having concurrently from putting out the carbon heat source with anti-drop function, belonging to novel tobacco arts.
Two, background technology
Satisfaction and tobacco flavor are generally passed to consumer by the mode heating not burning tobacco by low-temperature heat type cigarette, adapt to and meet the physiological requirements of consumer to a certain extent, simultaneously the mode of " heating do not burn " make tobacco only at a lower temperature (the interval 300-500 DEG C of ideal temperature) heated, effectively significantly can reduce multiple harmful components in flue gas.Its implementation is generally be separated physically with thermal source by tobacco, and therefore, thermal source is the core of its design.Wherein, carbon heat source is because having safety and stability, quickness and high efficiency, the advantage such as cheap, one of main heating source becoming low temperature cigarette.Be easy to for making carbon heat source light, and make heat effectively pass to spices section, carbon heat source in design General Requirements has higher porosity and high specific surface area, easily collapses and comes off when this makes carbon heat source burn.For preventing carbon heat source from coming off, patent CN102458165A, US4714082 and CN1886069A all carry out coated with glass fibre sleeve.But glass fibre can come off unavoidably and be adsorbed to that side of filter tip in the processes such as packed and transported, make smoker may in glass fibre suction body, health risk.In addition, when carbon heat source after-flame, it is desirable to certainly to put out, can not to ignite the remainder of low-temperature heat type cigarette to prevent carbon heat source.Patent CN1040496A then proposes a kind of thermal source that makes from the way put out, namely fixes thermal source securely with a clip enough large with carbon heat source contact area, and thermal source can oneself put out due to the under-supply generation of air when being burned to clip position.But so far, do not have a kind of simultaneously having concurrently certainly can put out the relevant report with the carbon heat source of anti-drop function.
Three, summary of the invention
For addressing the deficiencies of the prior art, the present invention proposes and a kind ofly have concurrently from putting out the carbon heat source with anti-drop function, coated section of this carbon heat source is heated can Self-expanding, effectively inhibits heat to collapse the problem causing carbon heat source to come off.
Technical solution problem of the present invention adopts following technical scheme:
The present invention has concurrently from putting out the carbon heat source with anti-drop function, it is characterized in that: described carbon heat source is the cylindric of length 10 ~ 20mm, its one end is freely unsettled, be called free segment, the other end is fixed, be called canned paragraph, the ratio of described canned paragraph length and whole carbon heat source length is 1:4.Being fixed herein refers to that carbon heat source is fixed with flue gas forming region in cigarette.
Described carbon heat source has 5 ~ 10 polygonal starlike vertical passages.
The raw material of described carbon heat source is constructed as follows by mass percentage:
Described binding agent is that guar gum and potassium alginate form with mass ratio 1:2.
With mould said components mixed and make the cylindrical heat source with 5 ~ 10 polygonal starlike vertical passages.
In Surface coating thick layer 500-1500 μm, the expanding layer that length is equal with canned paragraph length of described canned paragraph.The cylindric side that the surface of canned paragraph mentioned here comprises canned paragraph and the cylindric bottom surface be connected with flue gas forming region.
Described expanding layer is heated Self-expanding, and its raw material is constructed as follows by mass percentage:
Binding material 10-40%, vermiculite power 30-60%, graphite powder 15-50%, processing aid 0.5-2%.
Described binding material is at least one in alginate, carboxymethyl cellulose and salt thereof, pectin and salt, carragheen and salt thereof, guar gum, starch; Described salt is sodium salt, sylvite or ammonium salt.
Namely described vermiculite power starts to expand more than 150 DEG C.
The particle diameter of described vermiculite power is 100-500 order.
The particle diameter of described graphite powder is 100-300 order.
Described processing aid is at least one in tobacco tar, corn oil, soybean oil, peanut oil, paraffin oil.
The present invention has concurrently from putting out the preparation method with the carbon heat source of anti-drop function, it is characterized in that:
Thick 500 ~ 1500 μm, the satchel of internal diameter 2.5-5mm is made after binding material, vermiculite power, graphite powder and processing aid being sent into extruder mixing, and it is closely wrapped in canned paragraph one end of carbon heat source, obtain having concurrently from putting out the carbon heat source with anti-drop function.
Compared with the prior art, beneficial effect of the present invention is embodied in:
1, expanding layer is heated and can be expanded, the problem that effectively inhibit heat to collapse to cause carbon heat source to come off, and avoids the harm that the glass using the coated carbon heat source of the heat-insulating materials such as glass fibre to cause sucks human body.
2, during carbon heat source freedom unsettled section of after-flame, during intumescent layers, can heat be absorbed, and the contact of carbon heat source and outside air can be reduced after expanding, thus make carbon heat source from putting out, guarantee that the remainder of smoking article can not be lighted.
3, expanding layer materials safety is nontoxic, source is sufficient, easy to prepare.
