Abstract
A smoke filtering material for the smoking tool to decrease tar and harmful components is a cellular one and contains starch (100 Wt. Portions), PVC (15-25), citric acid (2-10), gypsum (5-15) and wooden pulp fibers (5-15). Its advantages are high effect and easy degradation.
Description
(1) technical field
The present invention relates to a kind of cellular flue filtering material, also relate to a kind of preparation method of described filtering material.
(2) background technology
Existing cigarette filter tip materials for example polypropylene fibre class filter-tip material is the difficult degradation material, is difficult to degraded in a century, causes the great difficult problem of white pollution.In addition, the existing filter stick tow combinations of directions of making is a S shape, can't stop alkoxy radical in the flue gas, and is relatively poor to the filter effect of harmful substance in the flue gas.
(3) summary of the invention
The flue filtering material that provides a kind of filter effect high is provided the object of the invention.
Flue filtering material of the present invention is characterized in that described material is cellular and comprises following components by part by weight:
100 parts of starch,
15～25 parts of polyvinyl alcohol,
2～10 parts of citric acids,
5～15 parts of gypsums,
5～15 parts of wood pulp celluloses.
Described starch, gypsum (CaSO
42H
2O), citric acid, wood pulp cellulose all belong to natural degradation material, polyvinyl alcohol is a water-soluble polymer, it and calcium sulfate, citric acid blend can improve degradation speed, thereby flue filtering material of the present invention is easy to degraded.This material also preferably contains 1～5 part of shitosan, and shitosan can be accelerated the degradation rate of material significantly, and shitosan combines with wood pulp cellulose and makes filtering material become bulk simultaneously, increases elasticity.
Be recommended in the triacetyl glycerine that adds 0.5～1 part in the component of described flue filtering material again, because flue filtering material hardens easily, show through inventor's experiment, the triacetyl glycerine that in this flue filtering material component, adds 0.5～1 part, can prevent that this filtering material from hardening, to guarantee that flue filtering material energy Da is to the hardness standard of tobacco business to cigarette filter.
Flue filtering material of the present invention, preferably form by following components by part by weight:
100 parts of starch,
15～25 parts of polyvinyl alcohol,
3～8 parts of citric acids,
5～15 parts of gypsums,
5～12 parts of wood pulp celluloses
1～3 part of shitosan.
Flue filtering material of the present invention, most preferably form by following components by part by weight:
100 parts of starch,
20 parts of polyvinyl alcohol,
5 parts of citric acids,
10 parts of gypsums,
8 parts of wood pulp celluloses,
1～3 part of shitosan,
0.5～1 part of triacetyl glycerine.
The present invention also provides a kind of preparation method of above-mentioned flue filtering material, and described preparation method comprises the steps: all components is mixed, through the double screw extruder granulation; Then particle is placed single screw extrusion machine to be heated to 140～160 ℃ of foaming, promptly get described flue filtering material through extruding again.
For technological operation in producing more convenient, usually in the time of also can in flue filtering material, containing triacetyl glycerine, earlier all components except that triacetyl glycerine is mixed, make flue filtering material by foregoing method, again the triacetyl glycerine in the component is sprayed on described filtering material surface.
Preferably, at the filter rod mould of described single screw extrusion machine head installation Φ 7.6～7.7mm, particle is extruded through single screw extrusion machine can obtain cigarette filter rod finished product.
The present invention is a base-material with starch/polyvinyl alcohol, is composite foamable agent with citric acid/gypsum, and wood pulp cellulose has played the effect of supporting the filter structures skeleton as filler.Described starch is preferably with potato or the pure starch of corn, because of purity of starch height wherein, strengthened frothing percentage thereby can dissolve and merge mutually with blowing agent at 70 ℃～80 ℃, can certainly adopt wood powder, paper powder.Citric acid, gypsum are that solid acid (and the gypsum powder can be used as the nucleator in the foaming system) the two material blend chance water of moderate strength is complete reaction, impel amylofermentation to produce the fine even bubble of carbon dioxide, thereby make the composite foaming and intumescing, and form cellular dense micro-hole structure, wood pulp cellulose is filled in the effect of playing the support frame structure in the foaming tissue, prevent that abscess from shrinking, thereby make filtering material have good intensity, prevented material bending, bad phenomenon such as distortion.
During very moment smoking gas, harmful substance such as solid formation, aerosol enters human oral cavity with the flue gas thermal current in the flue gas, and the obstruction rate of existing third fibre, sour fibre bundle filter structure is 10～25%.And micropore is fine and close evenly in the alveolate texture of the present invention, in the flue gas alkoxy radical extremely difficulty penetrate alveolate texture, the obstruction rate is 30～80%.Flue filtering material of the present invention is eliminated substantially to nanogram level harmful substances such as nitrosamines, hydrazine, vinyl chloride, benzanthracene, pyrene, benzene.Elimination factor 50～80% to Gamma Magnitude harmful substances such as nitrogen oxide, hydrogen cyanide, catechol, formaldehyde, methacrylaldehyde.Elimination factor to class milligram level harmful substances such as tar and polycyclic aromatic hydrocarbon, nicotine, carbon monoxide, acetaldehyde is 30～60%.Therefore, filtering material of the present invention is that stop on popularity ground to the harmful substance in the flue gas, and it is fairly obvious to eliminate effect.
Flue filtering material of the present invention can be as the filter stick of cigarette.Filter stick can be directly installed on and do the filter tip use on the cigarette, also can be socketed on the common filter tip, can also be installed in mouth biting type exhaust gases passes or the pipe type exhaust gases passes, in addition, filter stick of the present invention can also be compound with other filtering material be polynary combined filtration rod (referring to Fig. 1～7).Filter stick voltage drop value be generally 3300～3800Pa, meet the tobacco business standard fully.
In addition, often need to add spices in the tobacco product to improve its peculiar smell.A kind of method is that spices is directly added in the pipe tobacco, but spices at high temperature can cracking so that can be changed the smell of original spices.Another method is that the cotton that the moisture absorption of impregnated with fragrances is stronger embeds in the filter stick tow, but prepares technical the acquiring a certain degree of difficulty of this fragrant line filter tip.And filter stick of the present invention is a honeycomb microporous structure, extremely strong hygroscopicity is arranged, only need natural or synthetic spices is sprayed on cellular cigarette filter tip, can play the ideal effect of perfuming, the method perfuming ratio can be arbitrarily adjustable, and technology is very simple, and is easy to operate, sick behind the perfuming, can keep original fragrance during mouth smoking gas.
Common cigarette moisture-sensitive is mouldy, and cellular flue filtering material of the present invention has extremely strong moisture pick-up properties, and it is mouldy to prevent that cigarette from making moist.
Flue filtering material of the present invention has overcome poor filtration effect, has been difficult for the shortcoming of degraded, filter stick of the present invention is applied in the smoking set exhaust gases passes, have and significantly, popularity fall Jiao, reducing poison function, but and in 3 years natural degradation go back to nature.
