A kind of preparation method of filter material of cigarette
Technical field
The invention belongs to cigarette auxiliary material technical field, particularly the filtering material that adds in the cigarette filter and this preparation methods.
Background technology
Pipe tobacco and cigarette paper produce flue gas by burning, the cigarette filter flue gas that dams, the flue gas that finally forms the consumer and sucked.Filter tip becomes one of key link that reduces cigarette harm.The form of filter tip is rich and varied at present has excellent filter tip in binary composite filter tip, ternary composite filter tip, hollow filter tip, the rod, spices line filter tip and adsorbs line filter tip etc.Because the consumer strengthens day by day to the requirement of cigarette control harmfulness, become the research link of a key by the harm of cigarette filter attenuating cigarette.Wherein the burnt technology of falling on the basis of as far as possible losing the cigarette odor-absorbing style less is one of focus of paying close attention to.
By physical method, as the resistance to suction that increases filter tip, to regulate single total dawn at dawn, increase method such as ventilation rate be to reach reduction tar, reduces the function of harm, but to cigarette to suck the style influence bigger, and the scope of an adjustment is arranged.
Chinese patent application " rush cigarette with filter tip ", application number: 200420104785.9, disclose a kind of one or more rush by the cigarette with filter tip of cigarette filter axially-aligned in the mouth rod, mentioned this filter tip in the invention and can obviously reduce the cigarette harmfulness.But the rush structure is fluffy, frangible, do not have at present technology and equipment can with its according to the filter tip axially-aligned in the acetate fiber or the third fine mouth rod, can't industrialization.
Chinese patent application " method of structure with same quality and different profile with double formworks synchronously forming nano selenium super ", application number: 200510027805.6 and Chinese patent application " method of structure with same quality and different profile with double formworks synchronously barium salt nano-superstructure ", application number: 200510027806.0 utilize the template of rush as nano material preparation, do not relate to the adsorption function of flue gas aspect.But this shows to have abundant nano grade pore in the rush, this absorption to flue gas is very favourable.Chinese patent application " a kind of filtering material for cigarette filter tip and preparation method thereof ", application number 200710066121.6 discloses a kind of with the technology that joins after the granulation of microwave expansion offal in the mouth rod, the cabo particle flue gas that this technology is used can not pass, can only walk around, thereby have only simple interception function for flue gas aerosol, so it is very limited to lower tar.
At present the actual adsorption particle that uses is mainly activated carbon granule in cigarette, and its little molecule ability of damming is stronger, the harm that can lower cigarette, but it is very limited to lowering tar, and carbon granule can drop to the plume end and causes influencing cigarette odor-absorbing.
And report multiple falls burnt additive such as porous-starch, silicates as (sepiolite, bentonite, medical stone, zeolite and molecular screen material that some are synthetic or the like), tar and harmful components all there is separately advantage, but these materials all have the adding technology complexity, can introduce the deficiency of assorted gas after the burning.
Therefore, how by the sorbing material of natural plants, producing not obvious influence and inhale flavor and can reduce the material of coke tar in cigarette and harmful components, and have the availability of mouth rod suitability for industrialized production, is the product technology that present cigarette product very needs.
Summary of the invention
Purpose of the present invention is intended to overcome the defective of prior art, and providing a kind of is the cigarette adsorption particle of feedstock production with rush, and can effectively reduce the preparation method of the filter material of cigarette of tar and harmful ingredients in flue gas.
The preparation method of filter material of cigarette of the present invention, as raw material, by the cigarette adsorption particle that technologies such as load-carrying processing, drying, granulation form, its preparation method is with rush:
A, raw material: screening does not have and to go mouldy, color at milk yellow to the rush between the yellow;
B, rush are ingressed, length≤1cm;
C, the load-carrying agent is soluble in water adds on the rush;
D, stir normal temperature and pressure storage 1~12 hour down;
E, with steps d gained rush oven dry, dry to moisture≤8%;
F, the rush granulation after will drying, 95% particle is less than 10 orders;
G, the load-carrying agent is soluble in water adds step f gained to less than on the 10 order rush particles;
H, stir normal temperature and pressure storage 1~12 hour down;
I, with step h gained rush oven dry, dry to moisture≤8%;
J, with the granulation once more of rush particle, grade promptly gets described filter material of cigarette at 20~100 orders with interior.
The addition of the described load-carrying agent of step c is: the weight part ratio of raw material and load-carrying agent is 1: 1~5.
The described oven dry of step e is a microwave drying.
The addition of the described load-carrying agent of step g is: the weight part ratio of raw material and load-carrying agent is 1: 1~5.
The described oven dry of step I is a microwave drying.
The described grade of step j is at 20~100 purpose rush particles, and proportion is at 1.5~4g/cm
3Between.
Step j is described with the granulation once more of rush particle, and grade is at 25~80 orders, and the proportion of rush particle is 2~4g/cm

The preparation method of filter material of cigarette of the present invention, described load-carrying agent is a kind of in NaCl, natrium citricum, potassium citrate, natrium malicum, the potassium malate.
Load-carrying agent of the present invention is two kinds in NaCl, natrium citricum, potassium citrate, natrium malicum, the potassium malate, and it mixes part than being: 1: 1-5.
Load-carrying agent of the present invention be in NaCl, natrium citricum, potassium citrate, natrium malicum, the potassium malate more than two kinds.
The preparation method of filter material of cigarette of the present invention prepared and the rush particle, directly add in the mouth rod of cigarette, addition is that every millimeter proboscis rod adds 0.5mg~2.0mg.
The filter material of cigarette that adopts the method for the invention preparation and get, the rush microstructure is a space network, has aeration preferably, the tubule support of Gou Chenging also has the aperture simultaneously.And tube wall has been used to the template that nano material is made, and it is a large amount of nanometer level microporous to prove that its surface has.Flue gas is easier to pass network structure, and is adsorbed by rich hole tubulose, thereby reaches the effect of tar adsorption.But rush proportion own kicks the beam, and its granule has tangible agglomeration, and can not add in the mouth rod.Rush itself has a kind of blue foreign smell, can influence the suction flavor of cigarette, and the aesthetic quality is had negative effect, can not directly use in cigarette.Raw material of the present invention uses rush, after the load-carrying processing, crystal in the network structure plays the effect of flow-disturbing flue gas, the load-carrying agent of Jia Ruing simultaneously itself has the function that absorbs harmful ingredients in flue gas, can assist to fall evil, and particle proportion increases, agglomeration alleviates, after the microwave treatment, the blue foreign smell of rush is removed, thereby has formed a kind of new material that adds in cigarette filter tip simultaneously.
The preparation method of filter material of cigarette of the present invention, granular materials derives from the natural plants rush, and rush has possessed adsorbs flue gas characteristic preferably, can reduce by 7%~15% tar; After load-carrying, microwave treatment, the rush particle is less to cigarette odor-absorbing influence, and the load-carrying agent of being adopted has simultaneously and collaboratively falls harmful effect, can effectively significantly reduce tar and harmful ingredients in flue gas on the basis of cigarette odor-absorbing not being had obvious influence.The rush particle that preparation gets according to the method for the invention directly can directly use in conjunction with present mouth rod forming technology, and industrial applications is convenient.
