According to the method, EDTA-a-Na gamma-Al2O3 mesoporous composite materials are prepared with the dipping method, the EDTA-a-Na gamma-Al2O3 mesoporous composite materials are added into the cigarette filter rod, the release amount of chromium and the release amount of cadmium in cigarette mainstream smoke can be reduced accordingly, and the cigarette filter rod has the good effect on selective reduction of damage of cigarettes.
Description
Technical field
The present invention relates to cigarette filter rod technical field, be specifically related to a kind of containing EDTA-4Na/ γ-Al2O3The preparation method of cigarette filter rod.
Background technology
] tobacco cartridge made the tobacco product of strip, also known as cigarette, medicated cigarette, cigarette by Medicated cigarette (cigarette) with cigarette paper.Have filter tip cigarette and without mouth Medicated cigarette, have again flat taste and dense taste point.It is in 1890 that Medicated cigarette initially enters Chinese commodity market, and manufacture of setting up factories then starts from 1893, and production and marketing increases year by year.From 1980, Chinese cigarette yield occupied the first place of countries in the world so far, and 1989 annual productions are 3195.06 ten thousand casees (50,000/case).Medicated cigarette can produce the substantial amounts of material worked the mischief in combustion, including lead (Pb), nickel (Ni), hydrargyrum (Hg), cadmium (Cd), arsenic (As), selenium (Se), chromium (Cr) etc., wherein, chromium (Cr) is the heavy metal element that a kind of toxicity is higher, it may interfere with the reduction-oxidation progress of cell, also or with nucleic acid combine, cause that important enzyme system function is disturbed to stimulate digestion and respiratory tract, damage lungs and kidney, the nickel (Ni) in Nicotiana tabacum L. carbon monoxide in smog is combined, and smoker can be made to be susceptible to suffer from pulmonary carcinoma.Arsenic (As), especially trivalent arsenic, toxicity is high, and the As2O3 of 20mg then can be lethal.Selenium (Se) is useful to human body when keeping appropriate, too high, can cause the symptoms such as cardiorenal function obstacle, alopecia, diarrhoea.Lead (Pb) typically can cause intestinal mutation, causes hypertension, causes the symptoms such as anemia.Cadmium (Cd) then can disturb albumen, interference calcium, also can cause oxidative damage.Hydrargyrum (Hg) is very big to brain vision nerve damage.Containing 0.01 milligram in natural water every liter water, will strongly be poisoned.Hydrargyrum drinking water containing trace, is eaten for a long time and can cause retention toxicosis.
At present, the main method reducing the heavy metal in Medicated cigarette has improvement tobacco planting condition, improvement Nicotiana tabacum L. preventing from heavy metal gene, improvement Cigarette processing technique, application tobacco shred additive, novel harm reduction filter tip etc..But the regional soil property of cigarette is planted in extensive change and tobacco planting condition is extremely difficult, change cigarette processing technique limited to reducing Medicated cigarette content of beary metal effect, therefore tobacco shred additive is applied, the heavy metal release amount that novel harm reduction filter tip reduces in cigarette smoke is most effective feasible method, there is patent No. CN102835736A that chitosan does adsorbent the most at present and be applied to cigarette filter rod reduction tobacco heavy metal, or EDTA-4Na aqueous solution is processed Nicotiana tabacum L. or processes filter stick, also have and the blended absorbent adsorption layer of activated carbon and calcium hydroxide is applied in filter tip, but find no the extraordinary Application of micron of mesic hole compound in cigarette filter rod.
Summary of the invention
It is an object of the invention to, for prior art, it is provided that a kind of containing EDTA-4Na/ γ-Al2O3The preparation method of cigarette filter rod.
For achieving the above object, the present invention takes techniques below scheme: a kind of containing EDTA-4Na/ γ-Al2O3The preparation method of cigarette filter rod, comprise the following steps:
(1)EDTA-4Na/γ-Al2O3The preparation of mesic hole compound: take γ-Al2O3Granule, pulverizes, and crosses 40～80 mesh sieves, dries 2～3h in 110～150 DEG C, by EDTA-4Na H2O is dissolved in deionized water, with dried γ-Al2O3It is stirred at room temperature 45～50h, then moves to stir under 80 DEG C of constant temperature 30min, stirring thing is being filtered, the solid obtained is being dried, then solid is placed in EDTA-4Na H2O aqueous solution repeats absorption-filtration-drying and i.e. obtains EDTA-4Na/ γ-Al for 3 times2O3Mesic hole compound,
(2) preparation of binary compound filter candle: acetate silk bag is opened and placed in filter-stick forming device, arranges parameter for charging segment length 10mm, and do not feed segment length 15mm, simultaneously by forming paper, PUR, interior bonding wire glue, etc. the γ-Al of mass ratio2O3Granule and EDTA-4Na/ γ-Al2O3Mesic hole compound mixing preparation puts in place, and by plucker roller and loosening device, tow is fully deployed, uniformly apply γ-Al by plasticizer application system to fully deployed tow2O3Granule and EDTA-4Na/ γ-Al2O3Mesic hole compound mixture, feed segment length 10mm, is drawn in by the tow applying plasticizer, it is formed paper bag during by opium pipe part to wrap up in, forms cylindrical shape filter bar, cylindrical shape is filtered bar and cuts the filter stick into 100mm, filter stick is compiled by tray filling machine, is distributed into capsule.
Wherein, described EDTA-4Na H2O with the ratio of deionized water is: 1g:15～25ml.
Wherein, described EDTA-4Na H2The deionized water solution of O and γ-Al2O3Mixing ratio be: 20～25ml:10g.
Wherein, the monofilament linear density of described vinegar fiber bundle is 3.33dtex～3.56ktex, and monofilament cross section is Y type.
Wherein, the described γ-Al waiting mass ratio2O3Granule and EDTA-4Na/ γ-Al2O3The feeding quantity of mesic hole compound mixture is 1～2mg/mm.
Further, in Medicated cigarette in heavy metal be mainly presented in aerosol or metal-oxide, filter tip acetate fiber again is constituted, and heavy metal thing is without obvious adsorption effect, and EDTA-4Na/ γ-Al2O3Porous material, surface area is big, and superfine little aerosol and metal-oxide can enter in its duct, and heavy metal particulate is the most electrically charged, is trapped by electrostatic interaction, with the addition of EDTA-4Na/ γ-Al in filter plug in duct or during particle surface2O3After mesic hole compound, the burst size of Cr and Cd in flue gas can be made to reduce.
Further, EDTA-4Na/ γ-Al2O3For important metal complex, almost can be with all of metal generation complexing, aerosol or metal oxide microparticle at EDTA-4Na/ γ-Al2O3Duct in addition to adsorbed retaining, heavy metal therein can also and EDTA4+Occur complex reaction to be trapped, thus reduce the burst size of Cr and Cd in cigarette flue gas.
Further, EDTA-4Na/ γ-Al2O3Mesic hole compound is as the extraordinary nano material of medium porosity assembling system, there is specific surface area big, the advantages such as high adsorption capacity, it is applied in Medicated cigarette with the form of additive, after making Medicated cigarette can will reduce TPM in main flume, nicotine, moisture and tar content, moreover it is possible to optionally retain and be catalyzed harmful components.
The invention has the beneficial effects as follows: the present invention uses infusion process to prepare EDTA-4Na/ γ-Al2O3Mesoporous composite material, and made an addition in cigarette filter rod, the burst size of the chromium in cigarette mainstream flue gas and cadmium can be made to reduce, this cigarette filter rod has good effect for the selective harm reduction of Medicated cigarette.
