The filter contains layered double hydroxide additive, and the content of the additive in each filter is 10-30 mg. The cigarette filter containing layered double hydroxide is one or a compound of more than two at arbitrary proportion in magnalium layered double hydroxide, magnesium-iron layered double hydroxide, zinc-aluminum layered double hydroxide, zinc-iron layered double hydroxide and ferronickel layered double hydroxide. As for the cigarette prepared by the filter provided by the invention, the emission of the harmful ingredients such as hydrocyanic acid, benzopyrene, phenol, crotonaldehyde, ammonia and NNK in the cigarette mainstream smoke can be reduced by more than 25%.
Description
Technical field:
The invention belongs to the lowering harm and decreasing coking technical field of tobacco industry, be specifically related to a kind of cigarette filter that contains layered double-hydroxide that reduces cigarette mainstream flue gas harmful components burst size.
Background technology:
Present stage, tobacco business was faced with the multiple pressure of the World Health Organization and [Tobacco Control framework treaty]; On the other hand, along with improving constantly of living standard and quality of life, the contradiction between smoking and the health becomes increasingly conspicuous; To the cigarette security require increasingly high; Improve the cigarette security, the burst size that reduces harmful components in the cigarette smoke is the developing direction of international cigarette technology, also is the inevitable demand of development Chinese style cigarette.Seven kinds of harmful components carbon monoxide, hydrogen cyanide, Benzpyrene, phenol, crotonaldehyde, ammonia and 4-(methyl nitrosamino group) in the cigarette-4-(3-pyridine radicals)-1-butanone (NNK) burst size can effectively characterize cigarette mainstream flue gas biohazard property, and effectively reducing by seven kinds of harmful components is key problem in technology of realizing further lowering harm and decreasing coking work.
At present, exploitation has the research focus that the new material of tar and harm reducing function is current tobacco science and technology.Layered double-hydroxide (LDH) is one type and fills the lamellar compound that commutative anion constitutes by positively charged layers of metal hydroxides and interlayer.It is several to several nanometers that the interlamellar spacing of layered double-hydroxide is generally zero point, has strong covalent bond effect in the layer, and interlayer then is a kind of weak interaction force, as Van der Waals force with (or) electrostatic force.Layered double-hydroxide generally has micropore and meso-hole structure, and interlayer ion is prone to exchanged, and under certain conditions, some material (atom, molecule or ion) can overcome the active force between each layer of bedded substance and insert bedding void, forms intercalation compound.Layered double-hydroxide is applied to the many industries of national economy as high-performance catalysis material, sorbing material, infrared absorbing material, barrier material, biomaterial, medical material, parting material and functional aid material etc., and also demonstrates wide application prospect in fields such as functional materials such as light, electricity, magnetic and chemical industry micro elements.But also do not see related patent U.S. Patent No. and the bibliographical information used in cigarette lowering harm and decreasing coking field about it at present.Develop the layered double-hydroxide material that can be applicable to the tobacco business production and can significantly reduce cigarette mainstream flue gas harmful components burst size, have positive impetus for the lifting of tobacco business lowering harm and decreasing coking technical research level.
Summary of the invention:
For avoiding the existing in prior technology weak point, the purpose of this invention is to provide simple, the steady quality of a kind of production technology, can effectively reduce the cigarette filter of hydrogen cyanide in the cigarette mainstream flue gas, Benzpyrene, phenol, crotonaldehyde, ammonia and NNK burst size.
Technical solution problem of the present invention adopts following technical scheme:
A kind of cigarette filter that contains layered double-hydroxide that reduces cigarette mainstream flue gas harmful components burst size contains the layered double-hydroxide additive in the said filter tip, the content of said additive in every filter tip is 10-30mg.Adopt this kind filter tip cigarette to become cigarette to prop up, can effectively reduce hydrogen cyanide in the cigarette mainstream flue gas, Benzpyrene, phenol, crotonaldehyde, ammonia and NNK burst size.
Said filter tip is the binary composite filter tip; Alternately arrange by A section and B section and compoundly to constitute; Said A section is common acetate fiber section, and said B section is the acetate fiber section that contains layered double-hydroxide, and said B section is dispersed in by layered double-hydroxide that loose acetate fibres is intrafascicular to be formed.And the length ratio of said A section and B section is 1: 2～1, and the end of filter tip is the A section, and it is the B section that the front end of filter tip promptly contacts the pipe tobacco end.
Layered double-hydroxide is a kind of or any two above arbitrary proportion compounds of magnalium laminar double-hydroxide, magnesium iron layered double-hydroxide, zinc-aluminium layered double-hydroxide, zinc-iron layered double-hydroxide, ferronickel layered double-hydroxide.
Layered double-hydroxide interlayer anion is selected from carbonate particle or nitrate ion.
Layered double-hydroxide particle size range is 40-300nm; Granularity is the 50-300 order.
The layered double-hydroxide material is following as the principle that additives of filter tip reduces the cigarette mainstream flue gas harmful components: stratiform double-hydroxide material has micropore and meso-hole structure on the one hand, has stronger suction-operated for the harmful components in the main flume; On the other hand, layered double-hydroxide has many characteristics such as intercalation property, acid-base catalysis and redox catalysis between interlayer ion interchangeability, laminate, can effectively catch and catalyzed conversion harmful components in the main flume.
Compared with present technology, beneficial effect of the present invention is embodied in:
1, harm reduction effect is obvious.The layered double-hydroxide material that the present invention selected for use under the adding proportion scope of every filter tip 10-30mg, can reach and reduce in the main flume harmful components hydrogen cyanide, Benzpyrene, phenol, crotonaldehyde, ammonia and NNK burst size more than 25%.
2, the present invention does not have negative effect to the smoking property of cigarette quality.
3, the interpolation implementation is simple.In whole interpolation process, need not increase any production equipment, can not change existing production of cigarettes processing technology yet, technical implementation way is simple.
4, raw material is safe in utilization, and wide material sources, is easy to buying.
Below, the present invention is described further through the specific embodiment.
