Abstract
The present invention relates to modified polypropylene tow for cigarette.Fibre beam for polypropylene cigarette has cut-off filter preferably to the harmful components in the flue gas, can satisfy the requirement of cigarette filter material.Therefore, very fast in China's development.But the virgin pp filter tip can't satisfy the requirement of cigarette low toxicity, because too much to the nicotine cut-off filter, it is excited to make the smoker can not obtain due stimulation simultaneously.Modified polypropylene tow for cigarette provided by the invention promptly makes the polyacrylic fibres beam modifying with property-modifying additive, thereby reaches the purpose of cut-off filter selectively.Compare with the virgin pp tow, the cut-off filter of nicotine has been reduced by 18.6%, the tar cut-off filter has been improved 16.4%, especially the cut-off filter to main carcinogenic composition BaP in the tar has improved 80.6%, has reached the low toxicity requirement.And rod making rate has improved 10.6%.
Description
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 three kinds of macromolecule atactic polymers of property-modifying additive A.B.C, its chemical formula is:
Wherein: R
1, R
2Hydrogen, sulphonate-base, many hydroxyls ester group, hydroxyl;
R
3For hydrogen or carbon number are the alkyl of 1-7;
R
4.R
5.R
6Be hydrogen, many hydroxyls ester group, ester group, hydroxyl, alkyl;
M.N.X.Y.Z counts arbitrarily.
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, and the consumption of additive is constant, melt extrudes through screw extruder, makes 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 composition purpose of cut-off filter and low toxicity selectively in the flue gas, rod making rate improves 10.6%.Its performance has approached or has surpassed the cellulose acetate filter performance.
