Description
One, technical field
The present invention relates to a kind of carbon heat sources for having both self-extinguishment and anti-drop function, belong to new tobacco products field.
Two, background technique
Low-temperature heat type cigarette, which is generally passed to satisfaction and tobacco flavor by way of heating not burning tobacco, to disappear
Fei Zhe adapts to and meets to a certain extent the physiological requirements of consumer, and the mode of " heating is not burnt " makes tobacco only simultaneously
(300-500 DEG C of ideal temperature section) is heated at a lower temperature, can effectively be greatly reduced in flue gas it is a variety of it is harmful at
Point.Its implementation is usually to be physically isolated tobacco and heat source, and therefore, heat source is the core of its design.Wherein, carbonaceous
Heat source because have many advantages, such as safety and stability, quickly and efficiently, it is cheap, it has also become one of main heating source of low temperature cigarette.To make
Carbon heat source is easy to light, and heat is made effectively to pass to fragrance section, and carbon heat source generally requires higher hole in design
Gap rate and high specific surface area are easy to collapse and fall off when this makes carbon heat source burn.To prevent carbon heat source from falling off, patent
CN102458165A, US4714082 and CN1886069A are coated with glass fibre sleeve.But glass fibre exists
Can inevitably fall off during packed and transported etc. and be adsorbed to that side of filter tip, make smoker may in glass fibre suction body,
Harm health.In addition, in carbon heat source after-flame, it is desirable to be able to self-extinguishment, to prevent carbon heat source from will not ignite low-temperature heat type
The rest part of cigarette.Patent CN 1040496A then proposes a kind of method for making heat source self-extinguishment, i.e., is connect with one with carbon heat source
The sufficiently large clip of contacting surface product securely fixes heat source, and heat source can be due to the insufficient supply of air when being burned to clip position
Self-extinguishment occurs.But so far, without a kind of relevant report of carbon heat source for having both energy self-extinguishment and anti-drop function simultaneously.
Three, summary of the invention
For the defect for solving the prior art, the invention proposes a kind of carbon heat source for having both self-extinguishment and anti-drop function,
The problem of heated meeting Self-expanding of the cladding section of the carbon heat source, effectively inhibiting heat to collapse causes carbon heat source to fall off.
The present invention solves technical problem and adopts the following technical scheme that
The present invention has both the carbon heat source of self-extinguishment and anti-drop function, it is characterised in that: the carbon heat source is length 10
~20mm's is cylindric, and one end is freely hanging, referred to as free segment, and the other end is fixed, referred to as fixed section, the fixed section
The ratio of length and entire carbon heat source length is 1:4.Being fixed herein refers to that carbon heat source is formed in cigarette with flue gas
Area is fixed.
The carbon heat source has 5~10 polygonal starlike vertical passages.
The raw material of the carbon heat source constitutes as follows by mass percentage:
The binder is that guar gum and potassium alginate are formed with mass ratio 1:2.
Said components are mixed with mold and the cylindrical heat source with 5~10 polygonal starlike vertical passages is made.
500-1500 μm of a thickness, the expanding layer of length and fixed section equal length are coated on the surface of the fixed section.
The surface of fixed section mentioned here includes the cylindric side of fixed section and forms the cylindric bottom that area is connected with flue gas
Face.
The expanding layer is heated Self-expanding, and raw material constitutes as follows by mass percentage:
Binding material 10-40%, vermiculite power 30-60%, graphite powder 15-50%, processing aid 0.5-2%.
The binding material is alginate, carboxymethyl cellulose and its salt, pectin and its salt, carragheen and its salt, melon
At least one of your glue, starch;The salt is sodium salt, sylvite or ammonium salt.
Expansion takes place at 150 DEG C or more in the vermiculite power.
The partial size of the vermiculite power is 100-500 mesh.
The partial size of the graphite powder is 100-300 mesh.
The processing aid is at least one of tobacco tar, corn oil, soybean oil, peanut oil, paraffin oil.
The present invention has both the preparation method of the carbon heat source of self-extinguishment and anti-drop function, it is characterised in that:
Binding material, vermiculite power, graphite powder and processing aid feeding extruder are mixed evenly to prepare 500~1500 μ of thickness
M, the satchel of internal diameter 2.5-5mm, and by its tight in fixed section one end of carbon heat source, it obtains having both self-extinguishment and prevent
The carbon heat source for the function that falls off.
Compared with the prior art, the beneficial effects of the present invention are embodied in:
1, the problem of expanding layer is heated to expand, and effectively inhibiting heat to collapse causes carbon heat source to fall off, avoids use
The harm of glass sucking human body caused by the cladding carbon heat source of the heat-insulating materials such as glass fibre.
2, carbon heat source freely hanging section after-flame when, whens intumescent layers, can absorb heat, and can reduce carbonaceous after expanding
Contact of the heat source with outside air, to make carbon heat source self-extinguishment, it is ensured that the rest part of smoking article will not be ignited.
3, expanding layer materials safety is nontoxic, source is sufficient, it is convenient to prepare.
