Description
Technical field
The present invention relates to the manufacturing of cigarette or cigarette holder, be specifically related to the preparation method of the controlled cigarette filter rod of a kind of absorption property.
Background technology
The development of tobacco product and the application of cigarette additive have very close relationship.As far back as 16th century in the discovery of America by Columbus New World, Mexican American Indian had begun to add the mandarin orange mandarin oil to strengthen fragrance in tobacco at that time.The U.S. has all occurred the cigarette of spices and essence, Japan in 1850 respectively in nineteen twenty, and China is at the flavouring essence for tobacco that begins to occur odor types such as banana, Rum 20th century around the thirties.Fragrance is accepted by the people by tobacco is easier, and is pursuing the same of low tar content, how to guarantee that mouthfeel is without prejudice, and multiple odor additive becomes the successful key of cigarette enterprise.Under the overall situation of global Tobacco Control campaign, the burst size that improves harmful components in cigarette security, the reduction cigarette smoke is the developing direction of international cigarette technology, also is the inevitable demand of development Chinese style cigarette.
The research in existing cigarette additive field and use mainly concentrates on harm reduction, seasoning and the two has both three aspects, be main direction of studying with harm reduction or seasoning function again wherein, because the realization of simple function is relatively easy, correlation technique is comparatively ripe, but the research in above-mentioned two fields at present has the extramalization tendency, has some drawbacks.
The deficiency of harm reduction additive and relevant art:
At first, in order to reduce the harmful substance contents in the flue gas, pursue the high absorption property of filter stick, often realize by the interpolation of in filter stick, carrying out adsorbent, generally be to adopt the material that absorption property is good to be undertaken compound by various means and cigarette filter rod, active carbon for example, active carbon is a kind of comparatively widely as using in the cigarette sorbing material at present, its application mode mainly contains two kinds, a kind of is to be applied on the filter stick formation paper, but because flue gas mostly passes through in the middle of filter stick, forming paper is as the material of parcel filter stick, it is limited to add superincumbent charcoal absorption effect, so use less.
Another kind is that active carbon is placed in the filter stick, has the following disadvantages: 1. if directly add in the filter stick tow, activated carbon granule easily drops, and pollutes cigarette and props up production equipment.2. if the form of activated carbon granule with group is embedded in the filter stick, can have a strong impact on the resistance to suction that cigarette props up; As " CN201120409136.X monobasic active carbon cellulose acetate filter rod ", its filter core is distributed with the activated carbon granule group of some cryptomeres on axis, this technology is active carbon to be concentrated insert the filter stick center again after being one, though can reduce active carbon to the pollution of equipment and environment, can increase resistance to suction and make a large amount of moisture of cigarette smoke loss.3. above dual mode also exists: be to improve absorption property, the addition of active carbon is too much, and too concentrated, can cause the moisture loss in the flue gas serious, and is dry easily when cigarette props up suction, and the taste of cigarette is impacted; Reduce influence to flue gas moisture etc. if adopt to reduce the mode of activated carbon dosage, can relate to wire-beam forming, plasticizer spray solidify, change that the shaping paper bag is wrapped up in series of process parameter controlled condition such as bonding, during special the if cigarette filter stick of corresponding different model brand, these arts demands are frequently changed, and can have a strong impact on the ordinary production of enterprise.
Secondly, in recent years the relatively application of popular chitin fiber tow, normally the chitin fiber tow is added in the filter stick, but also exist and too pursue absorption property and ignore deficiency to cigarette taste-affect, as " a kind of coaxial core filter tip core material and preparation method thereof 200810058692X ", the diameter of chitin fiber heart yearn is limited 0.5-5mm, be because it mainly pursues the absorption property that improves filter stick, having ignored the chitin fiber that adds in the filter stick too much can cause a devastating effect to cigarette smoke, the serious original taste of cigarette that disturbs, make cigarette almost not have use value, also has the increase of chitin fiber consumption, certainly will increase the cost that single cigarette props up, too high cost can make cigarette enterprise not will consider this scheme of employing, and its practicality will be had a greatly reduced quality.
The deficiency of flavouring additive and relevant art:
Show according to related data, at present, the cigarette additive that possesses seasoning function that in cigarette, uses, mainly comprise pure tobacco oil, the extraction essential oil of spice berry, multiple synthetic perfume, participate in the uncertainty that burning brings in order to eliminate above-mentioned substance in use, basically all be that these additives are added filter stick, utilizing it to meet hot volatile characteristic sneaks in the flue gas, reach the adjusting smoke perfume, the purpose of taste, in fact, why the audient is more for cigarette, one of important factor is exactly itself to have unique fragrance, and under the prerequisite that guarantees security, state is exactly keep itself fragrance pure preferably, introduce too much odor additive and tend to water down the local flavor of tobacco itself, and the security of some additives also can't guarantee.
The improvement of tobacco plasticizer:
Triacetyl glycerine is a kind of important auxiliary agent in the filter tip forming process, and the Dichlorodiphenyl Acetate fibre bundle plays the effect of bonding curing, makes filter rod have better elastic, gas permeability and suitable hardness.
All the time, Dichlorodiphenyl Acetate fiber Study of Plasticizer mainly concentrates on improves its plasticising processability aspect, to its make filter stick have aspect the suitable absorption property research seldom.Mentioned with peppermint sustained release agent modification plasticizer making peppermint cigarette as Chinese patent CN1672600; Chinese patent CN1356071 mixes with plasticizer with the food additives with various local flavor styles such as perfume (or spice), sweet, sour, bitter, sufferings makes filter stick have perfume (or spice), sweet, sour, bitter, hot style; Chinese patent 200610163807.2 is made up of triacetyl glycerine and modifier, described modifier is tobacco extract, natural class essence and flavoring agent and synthetic class spices, and tobacco extract is selected from molecular clock Red River cigarette absolute oil, molecular clock stone forest cigarette absolute oil, carbon dioxide supercritical extraction Turkey cigarette absolute oil etc.; Natural class essence and flavoring agent is selected from vanilla beans extract, tomato extract, peppermint wet goods; Synthetic class spices is selected from Megastigmatrienone, vanilla lactone, ethyl maltol, Clary sage lactone, damascenone, fanesol, irisone, menthyl lactate etc., is used for effectively improving richness and the elegant sense of cigarette flavor.The main purpose of this technology is to improve the sucking quality of cigarette, and the substance classes of its interpolation is too much, and complex manufacturing does not relate to plasticizer is improved, to reach the research that makes filter stick possess suitable absorption property and flue gas moisture is lost little aspect.
Seek a kind of active carbon with good adsorption properties to be added in the cigarette filter rod, reach and make filter stick possess suitable absorption property, little to the flue gas moisture loss, and the method for adjustment of filter stick absorption property is simpler, is to solve the active demand of cigarette filter rod absorption property and flue gas quality balance for a long time to the little method of whole filter stick production technology influence.
