Abstract
The present invention relates to modified polypropylene tow for cigarettes, which has better filtering performance for harmful ingredients in smoke gas, and the requirements of cigarette filter material can be met. Hence, the present invention has high developing speed in China; but the pure polypropylene filter can not meet the requirements of harmfulless cigarettes, and meanwhile, as too much nicotine is filtered, a smoker can not obtain the due stimulation and the exhilaration. The present invention provides the modified polypropylene tow for cigarettes, namely that modifying additive is used for modifying the polypropylene tow, and thereby, the purpose of selective filtration is achieved. Compared with the pure polypropylene tow, the filtering performance for the nicotine is reduced by 18.6%, the filtering performance for tar is improved by 16.4%, the filtering performance for the benzo pyrene of the main carcinogenesis ingredient in the tar is improved by 80.6%, the harmfulless requirement is met, and the bar forming rate is improved by 10.6%.
Description
The modified polypropylene tow for cigarette of selective cut-off filter and production method the present invention relates to polypropylene (PP) modification, relate in particular to the modification of the fibre beam for polypropylene cigarette of selective cut-off filter.
Polypropylene tows is the linear high polymer of typical pure carbon hydrogen compound, and this polymer has cut-off filter preferably to the tar in the flue gas, nicotine, BaP, polycyclic aromatic hydrocarbon etc., can satisfy the requirement of cigarette filter material.Therefore, since 1986, come into one's own in states such as the U.S., Britain, Italy, Czech, especially China's development is very fast.But because existing polypropylene cigaratte filter does not also reach the low toxicity requirement to the cut-off filter of tar in the flue gas and main carcinogenic composition BaP, and too strong to the cut-off filter of the nicotine in the flue gas, make the smoker can not get due stimulations excitement.Existing polypropylene tows rod making rate is not high simultaneously.
Purpose of the present invention is exactly the above-mentioned shortcoming that exists at existing polypropylene cigaratte filter, a kind of selectively cut-off filtered modulated polypropene tow that has is provided, cigaratte filter with its manufacturing, different components in the flue gas had optionally cut-off filter, raising reduces the cut-off filter to nicotine to the cut-off filter of tar and BaP.Simultaneously, rod making rate is improved.
The present invention is achieved in that
With polypropylene (PP) and the blend of three kinds of macromolecule atactic polymers of property-modifying additive A.B.C, A, B, the chemical formula of C is:
Wherein: R1R2 is a hydrogen, sulphonate-base, many hydroxyls ester group, hydroxyl;
R3 is that hydrogen or carbon number are the alkyl of 1-7;
R4R5R6 is hydrogen, many hydroxyls ester group, ester group, hydroxyl, alkyl;
M, N, X, Y, Z are any positive integer.By any formula rate (weight ratio) mixing in following 7 kinds of prescriptions.
A∶PP＝0.3～2.0∶100；
B∶PP＝1.0～8.0∶100；
C∶PP＝0.3～5.0∶100；
A∶B∶PP＝0.3～2.0∶1.0～8.0∶100；
A∶C∶PP＝0.3～2.0∶0.3～5.0∶100；
B∶C∶PP＝1.0～8.0∶0.3～5.0∶100；
A∶B∶C∶PP＝0.3～2.0∶1.0～8.0∶0.3
～5.0∶100。Be spun into modulated polypropene tow through spinning-drawing machine.Also additive can be made master batch in advance; the formula rate of master batch (weight ratio) is: in above-mentioned formula rate; polyacrylic consumption is only got 3-10 part; the consumption of additive is constant; melt extrude through screw extruder; make master batch: with remaining polypropylene 97-90 part and master batch mixing, be spun into modulated polypropene tow then through spinning-drawing machine.The spinning spinneret orifice is a trilobal cross, and hole count is 10194 holes, and spinneret orifice draw ratio L/d is 3.57, and the spinning degree is 270 ℃, and the spinning nozzle draw ratio is 80-110 times, and the after-drawing multiple is 2.5-3.5 times, 90-125 ℃ of after-drawing temperature.
When the adding proportion of property-modifying additive is higher than aforementioned proportion, will cause difficulty in spinning, fracture of wire appears.When its adding proportion is lower than aforementioned proportion, will not cause modified effect good or to no effect.
Above-mentioned polypropylene and property-modifying additive formula rate (weight ratio) are more preferably:
A∶PP＝0.5～0.9∶100；
B∶PP＝1.5～6.0∶100；
C∶PP＝0.5～3.0∶100；
A∶B∶PP＝0.5～0.9∶1.5～6.0∶100；
A∶C∶PP＝0.5～0.9∶0.5～3.0∶100；
B∶C∶PP＝1.5～6.0∶0.5～3.0∶100；
A∶B∶C∶PP＝0.5～0.9∶1.5～6.0∶0.5
～3.0∶100。
This modulated polypropene tow is compared with the cigaratte filter of existing polypropylene tows manufacturing, modulated polypropene tow structurally has a large amount of micropores, crack and hole, on chemical property, have tar cut-off filter raising 16.4%, to the cut-off filter raising 80.6% of BaP, to nicotine cut-off filter minimizing 18.6%, the total cut-off filter raising 15.2% of smoke components, thereby reach the purpose of cut-off filter and low toxicity selectively of the composition in the flue gas, rod making rate improves 10.6%.Its performance has approached or has surpassed the cellulose acetate filter performance.
