Description
Technical field
The present invention relates to technical field of cigarettes, specifically a kind of modified cover of the crosslinking of Hydroxy-Ni-Al containing nanomorphic takes off
Stone additives of filter tip and its application.
Background technique
In recent years, with the raising required safety cigarette, the content of harmful matter in cigarette how is reduced, is had become
The topic of tobacco business and medical field general concern；Harm reduction techniques tar reduction also increasingly shows its importance.It is added using filter tip
Agent is a kind of extraordinary lowering harm and decreasing coking means.Although the research at present about cigarette adsorbent material is also more and more, really
The only active carbon additive of large-scale use.
Montmorillonite is a kind of excellent porous modified substrate material, has distributed in nature extensive, cheap, safe nothing
A variety of advantages such as evil.001 crystal face interlayer of montmorillonite is very small, by cation exchange, by the metal ion exchanged of needs into
Enter interlayer, form intercalation compound, the metallic compound of interlayer is rendered as the shape of Nano grade due to the limitation of interfloor height
State.The material better heat stability will not decompose under typical temperature.Most of all, montmorillonite is as a kind of food additives
And medical substance, there is good security guarantee.
Summary of the invention
The object of the present invention is to provide a kind of Hydroxy-Ni-Al containing nanomorphic crosslinking modified montmorillonite used additives of filter tip and its
Using, its specific surface area with higher can adsorb most of ingredient in flue gas, especially to ammonia in cigarette smoke etc. at
The burst size divided has good inhibiting effect.
The technical scheme is that
With Ni-Al crosslinking column-supporting agent na-montmorillonite interlayer carry out it is pillared after, be fixed on 001 crystal face interlayer of montmorillonite, obtain
The modified montmorillonite used additives of filter tip (Ni/Al (OH)-M) of the crosslinking of Hydroxy-Ni-Al containing nanomorphic.
Specifically sequentially include the following steps:
1) synthesis of na-montmorillonite: 100g montmorillonite is added in 1500mL water, sufficiently after swelling, is heated to 85 DEG C and is added
5g NaOH and 5g Na2SO43h is reacted, filters and washs 5 times, is ground after dry spare.
2) .Ni-Al is crosslinked the preparation of column-supporting agent: preparing the NiCl of 0.2mol/L respectively2With the AlCl of 0.2mol/L3It is water-soluble
Liquid stirs 2 h after 1:6 mixing by volume.The NaOH solution of 75 ml 0.4mol/L is instilled 100 with the speed of 1 ml/min
mlNiCl2And AlCl3Aqueous solution in, persistently stir 6 h stand 24 h of aging, all be added dropwise and whipping process in 60 DEG C of water-baths
In the environment of carry out.
3) takes 5g na-montmorillonite to be added in 500 ml deionized waters, persistently stirs 1h, to montmorillonite complete swelling
Afterwards, the good Ni-Al of 50 ml agings is added and is crosslinked column-supporting agent, and is vigorously stirred after 3 h stand 12 h and filters, is washed with deionization
It washs to no chloride ion (AgNO3Solution detection), and it is dry at 80 DEG C.
4) calcines dried Hydroxy-Ni-Al Pillared Montmorillonite sample (being abbreviated as Ni/Al (OH)-M) at 400 DEG C
3 H-shapeds are at stable Ni/Al2O3-M。
Wherein nickel, aluminium plasma are firmly strapped in 001 crystal face interlayer of montmorillonite in the form of hydroxyl compound, very
Hardly possible is detached from.Wherein due to stronger, the pillared significant effect of rigidity of nickel ion, the material of bigger serface can be obtained, and aluminium from
Son can effectively remove the Lewis alkaline components in flue gas, further, since hydroxyl is deposited since the Lewis of its own is acid
There is certain water retention property in, the material, flue gas moisture feeling can be improved.
In order to illustrate the Hydroxy-Ni-Al containing nanomorphic crosslinking modified montmorillonite used additives of filter tip the advantages of, the present invention text
With unmodified raw material montmorillonite (M) and the cross-linking modified montmorillonite of oxidation state nickel-aluminum formed after high-temperature calcination in this
(Ni/Al2O3- M) it is that comparison is illustrated.
The application of the modified montmorillonite used additives of filter tip of the above-mentioned crosslinking of Hydroxy-Ni-Al containing nanomorphic, can add described
Agent is added to be added in cigarette filter in a manner of particle；It can also be used with dry coating in the enterprising enforcement of filter tip forming paper.
The present invention is added a certain amount of containing nanometer under the premise of not changing the recipe ingredient of cigarette in cigarette filter
The modified montmorillonite used additives of filter tip of state Hydroxy-Ni-Al crosslinking；Experiment test is added through scanning electron microscope, physical absorption and cigarette,
Montmorillonite material its 001 crystal face interlamellar spacing after pillared significantly increases, and can effectively adsorb smoke components, and to ammonia etc.
Lewis alkaline components form selective absorption effect.The additives of filter tip has plasticity strong, and adsorption effect is good, and can be formed
The advantages that selective absorption, and it is cheap, it is applicable in efficient.
Detailed description of the invention
Fig. 1 is the modified montmorillonite used additives of filter tip amplification of the crosslinking of Hydroxy-Ni-Al containing nanomorphic of the present invention
SEM figure under 10000 times.
Fig. 2 is M, Ni/Al2O3The N of-M and Ni/Al (OH)-M2Physical absorption-desorption curve figure.
Specific embodiment
Ni/Al (OH)-M and Ni/Al2O3The synthesis of-M
1) synthesis of na-montmorillonite: 100g montmorillonite is added in 1500mL water, sufficiently after swelling, is heated to 85 DEG C and is added
5g NaOH and 5g Na2SO43h is reacted, filters and washs 5 times, is ground after dry spare.
2) .Ni-Al is crosslinked the preparation of column-supporting agent: preparing the NiCl of 0.2mol/L respectively2With the AlCl of 0.2mol/L3It is water-soluble
Liquid stirs 2 h after 1:6 mixing by volume.The NaOH solution of 75 ml 0.4mol/L is instilled 100 with the speed of 1 ml/min
mlNiCl2And AlCl3Aqueous solution in, persistently stir 6 h stand 24 h of aging.It is all added dropwise and whipping process is in 60 DEG C of water-baths
In the environment of carry out.
3) takes 5g na-montmorillonite to be added in 500 ml deionized waters, persistently stirs 1h, to montmorillonite complete swelling
Afterwards, the good Ni-Al of 50 ml agings is added and is crosslinked column-supporting agent, and is vigorously stirred after 3 h stand 12 h and filters, is washed with deionization
It washs to no chloride ion (AgNO3Solution detection), and it is dry at 80 DEG C.
4) calcines dried Hydroxy-Ni-Al Pillared Montmorillonite sample (being abbreviated as Ni/Al (OH)-M) at 400 DEG C
3 H-shapeds are at stable Ni/Al2O3-M。
Gained pillared montmorillonite material is the tiny solid powder of particle, and in order to characterize its microscopic appearance, we are to Ni/Al
(OH)-M has carried out scanning electron microscope (SEM) test.In the case where amplifying 10000 times, common agglomerated particle size generally exists
2-4 μm or so.
To Ni/Al (OH)-M, Ni/Al2O3- M and raw material montmorillonite M carries out N2Physical absorption test, gained adsorption-desorption
Curve is as shown in Fig. 2.The adsorption-desorption curve of three kinds of montmorillonite materials is integrally all rendered as IV type thermoisopleth, lag loop
It is rendered as H3 type.Therefore, pillared modification does not substantially change that the intrinsic feature of montmorillonite is laminar structured, and pore structure is with slit-type
Based on hole.It is the BET specific surface area data of each sample shown in table 1.
Table 1 M, Fe (OH)-M and Fe2O3The BET specific surface area of-M
| Sample name | BET specific surface area (m2/ g) |
| M | 39.63 |
| Ni/Al(OH)-M | 157.24 |
| Ni/Al2O3-M | 103.64 |
It can be seen that the Ni/Al formed after either Ni/Al (OH)-M is still calcined from the data in table 12O3- M, comparison are covered
De- stone raw material M, BET specific surface area and micropore specific area suffer from and significantly increase, and wherein Ni/Al (OH)-M increases
It is more obvious.
Using relevant criterion detection method respectively to M, Ni/Al (the OH)-M and Ni/Al that joined 5mg2O3The cigarette sample of-M
Product have carried out flue gas absorption test.In contrast to M and Ni/Al2O3- M, Ni/Al (OH)-M can significantly reduce total phase in flue gas
