Abstract
The invention discloses a carbonaceous heat source covered by a flame-retardant material. The carbonaceous heat source is composed of a carbonaceous heat source material which includes a plurality of triangular longitudinal runners therein and the flame-retardant material covering the periphery of the carbonaceous heat source material. By virtue of the flame-retardant covering layer, the problem that the carbonaceous heat source, when burnt, is easy to become fallen off is effectively avoided; and meanwhile, heat loss can be reduced to the greatest extent, and harm to human bodies in the case of the invasion of glass fibers when glass fibers and like heat-insulating materials are adopted to cover is avoided.
Description
One, technical field
The present invention relates to a kind of cigarette source materials, specifically a kind of carbon heat source coated by fire proofing, belongs 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 450-550 DEG C of ideal temperature) heated, effectively significantly can reduce multiple harmful components in flue gas.Its implementation is generally be separated physically with source materials by tobacco, and therefore, source materials is the core of its design.Wherein, carbon heat source material is because having safety and stability, quickness and high efficiency, the advantage such as cheap, one of main heating source becoming low temperature cigarette.For reducing thermal losses when carbon heat source burns, preventing it from coming off from smoking article, 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; The operation that glass fibre coated carbon heat source material require is extra has simultaneously been come, and this will certainly reduce production efficiency, increases cost.
Three, summary of the invention
The present invention aims to provide a kind of carbon heat source coated by fire proofing, to overcome the above-mentioned defect of the coated carbon heat source of glass, obtains the carbon heat source that a kind of production technology is simple, safe and reliable.
Technical solution problem of the present invention adopts following technical scheme:

Compared with the prior art, beneficial effect of the present invention is embodied in:
1, the present invention utilizes the coated carbon heat source of flame-retardant layer to avoid and usually in the process such as cigarette package, transport, falls to filter tip side by the carbon heat source that glass fibre is coated, thus avoids glass to suck the harm of human body.
2, whether flame-retardant layer clad of the present invention or not when thermal source burns, and easy ceramic, caducous problem when carbon heat source burns can be effectively prevent.
3, flame retardant cover of the present invention also has heat insulating function, can reduce the thermal losses of carbon heat source to greatest extent.
4, each materials safety of flame retardant cover of the present invention is nontoxic, source is sufficient, preparation is simple.
