Abstract
The invention discloses a grapheme type fiber cigarette filter and a preparation method thereof. The filter comprises a fiber carrier, wherein the fiber carrier is provided with a grapheme type material for absorbing harmful components in smoke. The filter loads the grapheme type material on a carbon fiber or acetate fiber carrier; and the carrier is added in the filter by adopting the binary filter production mode in the existing industries to produce a compound filter for absorbing harmful substances in the smoke which is generated when cigarettes are smoked. The filter applies unique phi absorption characteristics and higher surface active atom ratio of novel two-dimensional nanometer materials to efficiently absorb benzo [a] pyrene, volatile aldehyde ketone type cancer promoting molecules, phenol and HCN (Hydrogen Cyanide) under the condition of smaller adding quantity, so that the filter is environment-friendly and has no additional poison; as the amount is small and the effect is high, the harm of the cigarettes to human bodies is reduced under the condition of not influencing the inherent sensory quality of the cigarettes. And at the same time, the method has the advantages of simple technique, large-scale production and low cost, and has wide application foreground in the cigarette field of harm reduction and tar reduction.
Description
Technical field
The present invention relates to technical field of cigarettes, be specifically related to a kind of Graphene fiber cigarette filter and preparation method thereof.
Background technology
Produce NH in the cigarette burning process
3, the harmful substances such as CO, phenol, benzo [a] pyrene, HCN, crotonaldehyde, methyl nitrosamine pyridine radicals butanone (NNK), when suction, enter human body with flue gas and work the mischief.Cigarette filter can stop these materials to enter human body to a certain extent.
At first, cigarette filter is take single fibrous material as main, and is low to the adsorption efficiency of harmful substance; Afterwards, along with the development of material technology, the fibrous material of body phase composite fibre, ion-exchange fibre, metal or doped metallic oxide, nano carbon sol etc. were used to make by different way cigarette filter.As in CN101019692A, disclose a kind of in cellulose acetate equably blending account for the filter tip of the NACF of its certain weight proportion, improved filter stick or filter tip to the adsorption efficiency of volatilization and half volatile harmful substance in the main flume; In CN1652703A, a kind of filter tip is disclosed, this filter tip contains the fiber of a branch of energy loaded particle thing, bead or powder, helps reduce flue gas composition.These methods have all reduced the harmful components in the cigarette mainstream flue gas to a certain extent, but because traditional macromolecular material or metallochemistry material itself have the characteristics such as poor selectivity, low, the active conjugation of polarity site are few, take physical absorption as main, lower to the adsorption efficiency of harmful substances in flue gas to the suction type of harmful substance.
Along with the development of nanometer technology, nano material is applied to the every field of productive life gradually.Nano composite material is applied to the research of harmful components in the selective absorption cigarette mainstream flue gas shows up prominently, although very limited, all obtained good effect.(Feng Shouai etc., the nanometer SiO such as Feng Shouai
2The research of harmful components in the selective absorption cigarette mainstream flue gas, the material Leader, 2011,25,44-46) reported nanometer SiO the end of the year 2011
2Make dispersion liquid and be injected in the mouth rod, the result show benzo in the flue gas [a] pyrene, phenol and crotonaldehyde content more than 8%; Xu Yihua makes efficient tobacco filters (patent No.200810063747. 6) with nano carbon sol, thinks that effect is fine.Although nano carbon sol has more adsorption activity site, also have simultaneously complicated components, the surface atom number does not reach best with the ratio of total atom number, and to the shortcomings such as poor selectivity of absorbed component.
Graphene (Graphene) be a kind of by carbon atom with sp
2Hybridized orbit forms the brand-new two-dimensional nano material of cellular regular hexagon lattice, except the characteristic with common nano material, also has unique p key conjugation suction-operated and chemical catalysis activity.It was found the rear global research boom that evoked rapidly, and the finder also obtained Nobel Prize in physics in 2010.It is prize-winning, and the Graphene that has its source in has extremely good character in absorption, catalysis etc. aspect numerous.Graphene oxide (Graphene oxide) is the direct derivative of Graphene, and Graphene has the character of improvement relatively, such as surface rich abundant hydroxyl and carboxyl functional group, has better water-soluble than Graphene.In addition, (comprise the H-p effect, p-p effect, p except the good p suction-operated that has kept non-oxide Graphene
Cation-p effect, cation-p effect, anion-p effect, and non-polar gas-p effect) and catalytic property outside, also easily with hydroxyl, amino, carboxyl isopolarity group formation hydrogen bond, polar molecule is had better characterization of adsorption.Therefore Graphene and graphene oxide have good selective absorption effect to conjugated molecule, base, porphyrin, aldehyde ketone molecule etc.In addition, (B. Huang, Z. Li, Z. Liu, G. Zhou, S. Hao, J.Wu, B. Gu, W. Duan, the J. Phys. Chem. C 2008,112,13443 such as B. Huang.) report Graphene regular hexagon lattice and NH
3The molecular size coupling, the gas molecules such as adsorbable nitrogen oxide.
At present, Graphene and graphene oxide are applied to every field in a plurality of fields, but so far, Graphene and graphene oxide fall burnt field at Harm reduction techniques and there is not yet Patents and bibliographical information, also do not obtain introducing and using.The of new generation two-dimensional nano material of the present invention take Graphene as representative is applied to Harm reduction techniques and falls Jiao and will bring new breakthrough as the cigarette technology.
Summary of the invention
Goal of the invention: for the deficiencies in the prior art, the purpose of this invention is to provide a kind of Graphene fiber cigarette filter and preparation method thereof, the harmful substance that produces in the flue gas during efficient selective absorption cigarette smoking, do not affecting in the cigarette in the aesthetic quality, reducing smoking to the harm of human body.
Technical scheme: in order to realize the foregoing invention purpose, the technical solution used in the present invention is as follows:
