Abstract
A modified activated carbon fiber (ACF), TiO2-Pd-Cu based ACF, for filtering out the tar, nicotin, CO, benzo(a) pyrene, fatty aldehyde, etc from the smoke of cigarette is prepared through adding ethanediol monomether into the solution of titanium sulfate, stirring, adding ACF, heating, adding the saturated solution of ammonium dicarbonate, regulating pH value, baking ACF, sintering, cooling, immersing in the aqueous solution of PbCl2 and CuCl, baking and cooling.
Description
Technical field
The present invention relates to a kind of cigarette filter with filtering material and preparation method thereof, is that harmful modified active carbon fiber and preparation method thereof falls in a kind of tobacco smoke filter element that is used for specifically.
Background technology
Contain harmful substances such as tar, CO in the cigarette smoke, the present above-mentioned two kinds of component contents of most of homemade Virginian-type cigarettes are respectively: 15～17mg/ and prop up, and 14～16mg/ props up.On May 21st, 2003, " Framework Convention on Tobacco Control " passes in the 56th World Health Assembly.On November 10th, 2003, Chinese Government's signature " Framework Convention on Tobacco Control ", the Chinese government promises to undertake that the box mark tar content of producing later on July 1st, 2004 must not enter the selling market at the cigarette more than 15 milligrams/; And the average tar content that makes homemade cigarette gradually be reduced to 12 Bos grams/about.Yet both contained some harmful substances in the tar, and contained the harmless fragrance matter of many kinds again, and reduced the content of T/N too much, and will have a strong impact on the fragrance of cigarette and jealous, the consumer is difficult to accept.Therefore, under the prerequisite that keeps intrinsic fragrance of cigarette and style and features such as jealous, as far as possible selectivity, remove harmful substance in the cigarette smoke in proportion, be the research direction of this area, also be the target always pursued of tobacco business for a long time.At harmful substance in the Virginian-type cigarette flue gas, people have carried out a large amount of theories and experimental study, have developed many harmful technology of falling.NACF is a kind of new and effective sorbing material, has obtained using widely and demonstrating good growth momentum in fields such as waste gas pollution control and treatment, air cleaning and waste water controls.The U.S., Japan etc. have developed NACF or composite active carbon fibre cigarette filter, though it has tangible filter effect to tar, nicotine, fatty aldehyde material etc., but relatively poor to strong carcinogen benzo [a] pyrene filter effect, CO then almost there is not clean-up effect.In addition, because it can not reduce T/N in proportion, thereby the fragrance of cigarette there is considerable influence.Domesticly developed the binary compound filter candle that contains the nano-noble metal catalysis material and be applied to production of cigarettes, be intended to reduce the CO in the cigarette smoke, but too high because of its cost, and the suction security is difficult to guarantee, so do not obtain large-scale application as yet.
Summary of the invention
Technical problem to be solved by this invention is to remedy the defective that prior art exists, provide a kind of and keeping intrinsic fragrance of Virginian-type cigarette and style and features such as jealous, under the prerequisite without any side effects, can reduce content of harmful such as tar, nicotine in the cigarette smoke in proportion, alternative again benzo [a] pyrene of removing also has modified active carbon fiber of tangible removal effect and preparation method thereof simultaneously to CO.
The present invention is used for tobacco smoke filter element and falls harmful modified active carbon fiber, is TiO
2-Pd-Cu based active carbon fiber (TiO
2-Pd-Cu base ACF), promptly on NACF load nano-TiO
2And Pd, Cu element.
Described NACF makes with following method:
In being 2～5% titanium sulfate solution, the titanium sulfate mass fraction adds glycol monoethyl ether; the addition of glycol monoethyl ether is 0.3～0.5% of a titanium sulfate solution quality; back adding NACF (ACF) stirs; the addition of ACF is 2～3% of a titanium sulfate solution quality; be heated to 85～95 ℃; after 1～1.5 hour, add the ammonium hydrogencarbonate saturated solution; regulate pH value to 5～6 of feed liquid; with deionized water rinsing to pH to 6.5～7.5; taking out ACF toasted 1～2 hour under 120～150 ℃ of conditions; under the situation of ammonia (normal pressure) protection,, be cooled to the normal temperature below 40 ℃ then 400～500 ℃ sintering temperature 1～1.5 hour.The ACF that obtains puts into PdCl
2In the CuCl mixed aqueous solution, PdCl in this mixed aqueous solution
2Be respectively 0.04%～0.1% and 0.2%～0.5% with the mass fraction of CuCl, all the other are water.The addition of ACF is PdCl
2With 1～2% of CuCl mixed aqueous solution quality, flood after 2～3 hours, in 120～150 ℃ baking oven, kept 3～6 hours, cooling makes TiO then
2-Pd-Cu base ACF.
Described NACF is a viscose-based active carbon fiber.
The present invention is used for the preparation method that harmful modified active carbon fiber falls in tobacco smoke filter element:
In being 2～5% titanium sulfate solution, the titanium sulfate mass fraction adds glycol monoethyl ether; the addition of glycol monoethyl ether is 0.3～0.5% of a titanium sulfate solution quality; back adding NACF (ACF) stirs; the addition of ACF is 2～3% of a titanium sulfate solution quality; be heated to 85～95 ℃; after 1～1.5 hour, add the ammonium hydrogencarbonate saturated solution; regulate pH value to 5～6 of feed liquid; with deionized water rinsing to pH to 6.5～7.5; taking out ACF toasted 1～2 hour under 120～150 ℃ of conditions; under the situation of nitrogen (normal pressure) protection,, be cooled to the normal temperature below 40 ℃ then 400～500 ℃ sintering temperature 1～1.5 hour.The ACF that obtains puts into PdCl
2In the CuCl mixed aqueous solution, PdCl in this mixed aqueous solution
2Be respectively 0.04%～0.1% and 0.2%～0.5% with the mass fraction of CuCl, all the other are water.The addition of ACF is PdCl
2With 1～2% of CuCl mixed aqueous solution quality, flood after 2～3 hours, in 120～150 ℃ baking oven, kept 3～6 hours, cooling makes TiO then
2-Pd-Cu base ACF.
Harmful modified active carbon fiber falls in the tobacco smoke filter element that is used for the inventive method preparation, make the cigarette composite filter-tip with acetate fiber or polypropylene fiber by certain segmentation scales, do not changing cigarette flavor and jealous, under the prerequisite without any side effects, can make tar, nicotine, carbon monoxide, benzo [a] pyrene and fatty aldehyde material in the cigarette smoke reduce 20-30%, 15-20%, 10-20%, 17-40%, 45-50% respectively simultaneously, both kept the intrinsic style and features of cigarette, make flue gas pureer and milder, greatly reduce the harmfulness of cigarette again.
