Description
Technical field
The invention belongs to cigarette field, be specifically related to a kind of method of thread carbon heat source material for cigarette that utilizes acid to prepare to use on low temperature cigarette.
Background technology
There are some researches show, nicotine and most tobacco flavor composition at a lower temperature (300 ~ 500 ℃) just can be transferred in flue gas.If cigarette temperature is reduced to 600 ℃ following (approximately 700 ℃ of tobacco burning-points), the multiple harmful components of flue gas can significantly reduce, and the impact that flavor component is subject to is relatively little.Therefore, a kind ofly use the cigarette that carbon heat source carries out destructive distillation tobacco component to be invented, wherein, what the Eclipse cigarette carbon heat source of R.J. Rainolds Tobacco CO. adopted is the mode of glass fibre parcel carbon-point, yet, carbon-point is that extruding forms, inner closely knit, for forming thermal current, need the ventilative glass fibre of outer parcel, there is research to think, this particle enables to be held back by filter tip material, but in the processes such as packing, be adsorbed onto on filter tip unavoidably, thereby cause sucking, health risk, simultaneously, the also more very thin carbonaceous filamentary material difficult point combustion of closely knit carbon-point.
Summary of the invention
The object of the invention is for above-mentioned deficiency, the preparation method of a kind of new cigarette with thread carbon heat source material is provided, carbon heat source prepared by employing the method is owing to being deposited in together when making carbon heat source, itself is loose, there is gap, thermal current can pass through smoothly, does not therefore need to adopt the glass fibre being detrimental to health to wrap up.
Above-mentioned purpose is achieved through the following technical solutions:
A kind ofly utilize acid to prepare the method for thread carbon heat source material for cigarette, comprise the following steps: sodium alginate or ammonium alginate or potassium alginate are mixed with carbon dust and water, stir furnishing jelly, wherein the mass ratio of sodium alginate or ammonium alginate or potassium alginate and carbon dust is 1:5-45, then described jelly is squeezed into silk thread, described silk thread is fully contacted with the acid solution of pH≤3, obtain solidfied material; Described solidfied material, through rinsing, dry, makes moisture reach 10-20%, obtains thread carbon heat source material for cigarette.
Preferably, described acid solution is selected from sulfuric acid, hydrochloric acid, nitric acid, oxalic acid, salicylic acid, tartaric acid, citric acid, malic acid or first aqueous acid.
Preferably, the granularity of described carbon dust is 100 orders.
Preferably, described silk thread diameter is 1-3mm.
Preferably, in the step that sodium alginate or ammonium alginate or potassium alginate mix with carbon dust and water, also comprise and add graphite powder, the mass ratio of described sodium alginate or ammonium alginate or potassium alginate and carbon dust and graphite powder is 1:5-45:0.4-3.6.Adding graphite powder is the heat transfer effect that is firing rear carbon in order to improve, and reduces ignition temperature, reduces CO and generates.
Preferably, in the step that sodium alginate or ammonium alginate or potassium alginate mix with carbon dust and water, also comprise and add CaCO
3, described sodium alginate or ammonium alginate or potassium alginate and carbon dust and CaCO
3mass ratio be 1:5-45:0.1-2.Add CaCO
3to produce in order to contribute to moulding and to reduce CO.
Preferably, in the step that sodium alginate or ammonium alginate or potassium alginate mix with carbon dust and water, also comprise and add Na
2cO
3the aqueous solution, described sodium alginate or ammonium alginate or potassium alginate and carbon dust and Na
2cO
3the mass ratio of solid is 1:5-45:0.05-1.Add Na
2cO
3in order to improve the combustibility of carbon dust after moulding.
Further preferably, in the step that sodium alginate or ammonium alginate or potassium alginate mix with carbon dust and water, also comprise and add graphite powder, CaCO
3and Na
2cO
3the aqueous solution, described sodium alginate or ammonium alginate or potassium alginate and carbon dust and graphite powder and CaCO
3with Na
2cO
3the mass ratio of solid is 1:5-45:0.4-3.6:0.1-2:0.05-1.
In order to improve igniting and sucking quality, in the step of mixing with carbon dust and water at sodium alginate, ammonium alginate or potassium alginate, can also add tobacco powder or tobacco extract or essence.
In the step that sodium alginate or ammonium alginate or potassium alginate mix with carbon dust and water, best sodium alginate or the mass ratio of ammonium alginate or potassium alginate and carbon dust and water are 1:20:100, now the modest viscosity of sodium alginate or ammonium alginate or the potassium alginate aqueous solution, can stir furnishing jelly with carbon dust at an easy rate.
The invention has the beneficial effects as follows:
1) while preparing, jelly is when contacting with acid solution or calcium salt soln, sodium alginate in jelly, ammonium alginate or potassium alginate and acid react, generate alginic acid, this compound is water insoluble, thereby form, wrapped up carbon dust, the solidfied material of the raw materials such as graphite powder, use this material, itself there is natural space in the latter made carbon heat source of chopping, flexible, be convenient to cigarette processing, and traditional carbon-point is extruding formation, inner closely knit, for forming the needs of ventilative and cigarette flexibility, skin will wrap up ventilative glass fibre, therefore the carbon heat source in the present invention no longer needs to wrap up with glass fibre, thereby the harm that has reduced glass fibre suction human body and caused.
2) because alginic acid carries out when there is chemical reaction with parcel with carbon dust, graphite powder etc. mixing of raw material, and be swift in response, after film forming, no longer there is viscosity, therefore the applicable industrial mass of carbon heat source material is processed continuously, and makes the thread rear carbon-point forming than extruding and more easily light.
3) the inventive method is simple, with short production cycle, and cost is low.
