Abstract
The present invention relates to a substance for reducing the contents of tar, etc. in cigarette smoke. The substance comprises activated carbon or activated carbon fibers, various iron or ferrous compounds or various copper or cuprous compounds and rare earth compounds. People can feel comfortable when smoking cigarettes produced by the technique, and the contents of harmful substances comprising tar, nicotine, etc. in cigarette smoke can be effectively reduced, so the present invention satisfies smokers' requirements, reduces the harm to smokers, and has favorable social benefit.
Description
Technical field
The present invention relates to a kind of harmful substances that falls that reduces harmful substance contents such as tar in the cigarette smoke.
Background technology
Along with the rise of world's anti-smoking campaign and development and the consumer concern to " smoking is with healthy " problem, people will pay attention to smoker's health more in the cigarette process of consumption.Cigarette smoke is dimerous by gaseous substance and granule phase substance matter.Gaseous substance is meant particle diameter less than 0.2 micron particulate, comprising oxynitrides, hydrocarbon, organic steam, some bioactivators, excessive nitrogen and air etc.Granule phase substance matter mainly contains water, nicotine and tar, and tar is that organic substance in cigarette shreds imperfect combustion under anoxia condition produces, the complex compound of being made up of oxide, sulfide and the nitride etc. of multiple hydro carbons and hydrocarbon.Because of state's inner wrap strip is mainly fire-cured tobacco type, the tar content height of the tobacco leaf that is adopted own, compare with external blended type cigarette, falling burnt engineering difficulty more strengthens, yet, for adapting to the concern of Chinese Consumer's to health, the low harm of exploitation low tar cigarette is imperative, and how reducing tar and reducing harm is the important topic of current cigarette research.
Falling in the burnt research in the past, high saturating cigarette paper, forming paper, filter tip ventilation dilution technology and the composite tip sticks etc. of adopting more.It is not very remarkable using high saturating cigarette paper and forming paper effect; Filter tip ventilation dilution technology is influenced big when detecting content of material such as tar down at following puffing regimens (partly or entirely ventilate stop up); Domestic and international research report to composite tip stick is a lot, nearly all is that the big material of specific area is added the mouth rod, comes tar-reducing harm-reducing from the angle of absorption, as Chinese patent 90107292.3, adding mouth rods such as active carbons.In the research at home, it is carrier with the reconstituted tobacoo that the people is arranged, and adds in the cigarette falling burnt material, as Chinese patent 94113133.5, adding thin slices such as sepiolite is made cigarette, but it is not remarkable to fall burnt effect; US4286604 adds fiber after the charing to phosphate etc., and the back that fries batter in a thin layer adds cigarette, and its effect mainly is to reduce gaseous substance content, and it is also not obvious to fall burnt effect.
Summary of the invention
The purpose of this invention is to provide a kind of harmful substances that falls that reduces harmful substance contents such as tar in the cigarette smoke.
The objective of the invention is to realize by following manner:
The harmful substances that falls provided by the invention: form by active carbon or NACF, various iron or ferrous compound or various copper or cuprous compound, rare earth compound; Active carbon or NACF can be chosen any one kind of them in cigarette or be used simultaneously, fall that its total amount is 2-95% in the harmful substances; Iron or ferrous compound, copper or cuprous compound can be allocated arbitrarily in falling harmful substances, fall that total amount is 0.5-70% in the harmful substances; Falling harmful substances middle rare earth compounds content is 0.1-30%; By weight.
Described active carbon refers to wood activated charcoal, active fruit shell carbon, asphalt based active carbon and the active carbon that is come by other raw material preparing.
Described NACF refer to polyacrylonitrile based NACF, cellulose-based NACF, phenolic aldehyde be NACF, pitch be NACF, wooden be NACF.

Active carbon or NACF can be chosen any one kind of them in cigarette or be used simultaneously, fall that preferable range is 40-80% in the harmful substances; Iron or ferrous compound, copper or cuprous compound can be allocated arbitrarily in falling harmful substances, fall that preferable range is 15-55% in the harmful substances; , falling harmful substances middle rare earth compound preferable range content is 1-10%; By weight.
Falling harmful substances can add cigarette with the form of thin slice, can be made into extraordinary cigarette paper and is applied in the cigarette or directly and sprays in the pipe tobacco.
Falling the addition of harmful substances in cigarette is the 1-70% of pipe tobacco percentage by weight;
Compared with the prior art the present invention has remarkable advantage:
A. this production technology can be applied on the cigarette of different tar contents, and it is remarkable to fall burnt effect.
B. use the cigarette that this technology is produced, its tar content can be regulated according to falling the consumption of harmful substances in cigarette, and consumption is big more, and tar content is low more.
C. use the cigarette that this technology is produced, because its sufficient combustion, the fragrance matter that is discharged is good, the perfume quantity foot, and it is graceful more comfortable to inhale flavor.
D. the raw materials used cheapness of this technology prepares simple, easy to operate.
E. the cigarette that uses the present invention to produce, it is inhaled, and the flavor gracefulness is comfortable, harmful components significantly reduce, and it effectively reduces, and the tar percentage by weight had both satisfied smoker's hobby more than 20% in the cigarette smoke, significantly reduced harm again, had good social benefit smoker self.
The preparation that the present invention is proposed to fall harmful substances is illustrated below.
