Topic.In recent years, it is reduction cigarette harmfulness, protects the health of smoking consumer, expanded widely in Harm reduction techniques field
Research, is a kind of method more commonly used by adding harm reduction material or sorbing material in tobacco or filter tip.
Phenol is larger to health effect a kind of pernicious gas in cigarette mainstream flue gas, although existing portion in the prior art
Research of the minute hand to sorbing material used in phenol in reduction cigarette mainstream flue gas, but there is not yet preferably add such material
Being added in filter tip is used to adsorb, reduce the composite filter tip of phenol release amount in cigarette mainstream flue gas.
In the prior art, it is mostly single acetate fiber unitary filter stick for manufacture cigarette filter, to reduction cigarette
Although the harmful substance of main flume have certain effect, absorption harmful substance when exist it is non-selective, and harm reduction effect compared with
For limited defect.Molecularly imprinted polymer (Molecularly Imprinted Polymer, MIP) is one kind by function
Monomer is polymerize in the presence of crosslinking agent around template molecule（Template molecule is removed after the completion of polymerization）Resulting space
The Polymer adsorption material that structure and binding site are matched completely with template molecule.Molecular imprinted polymer on surface (Surface
Molecularly Imprinted Polymer, SMIP) it is, using silica gel, organic polymer or capillary etc. as carrier, to utilize
The polymer that molecular imprinting technology is prepared, its recognition site is fixed on surfaces of carrier materials, beneficial to elution and recognition template
Molecule, and have the advantages that stable mechanical performance, mass transfer rate are fast, monodispersity is good and particle diameter distribution is uniform.Should due to utilizing
Polymeric material prepared by technology and template molecule have preferable adhesion, thus targetedly can adsorb or reduce predetermined substance and contain
Amount.But in the prior art there is not yet preferably utilizing harmful substance, especially targeted use in the specific reduction cigarette of the technology
In the relevant report of cigarette filter stick.
The content of the invention
The application purpose is the fine binary composite filter of vinegar for providing phenol in a kind of alternative reduction cigarette mainstream flue gas

Details are as follows for the technical scheme that the application is taken.
A kind of fine binary compound filter candle of the vinegar for reducing phenol in cigarette mainstream flue gas, the filter stick includes filter core, is wrapped in
Interior integument and outer casing on filter core；Wherein filter core be binary composite filter element, by acetate fiber section and be loaded with phenol-point
Son sieve molecular imprinted polymer on surface（SMIP）The acetate fiber section of material is uniformly alternate to be bonded.
The fine binary compound filter candle of the vinegar for reducing phenol in cigarette mainstream flue gas, with the conventional cigarette filter stick of 25mm length
Exemplified by, it is loaded with phenol-molecular sieve surface molecularly imprinted polymer（SMIP）The a length of 15mm of acetate fiber section of material, load capacity
For 10 ~ 30mg, specific for example, 20mg.
Phenol described herein-molecular sieve surface molecularly imprinted polymer（SMIP）Material, is prepared according to prior art
Form, be specifically for example prepared from by hydrothermal synthesis method, during preparation, specifically for example：With γ-（Methacryloxypropyl）Propyl group three
Methoxy silane（γ-MPS）The molecular sieve of modification is carrier, using phenol as template molecule, with 4-vinylpridine（4-Vpy）For
Function monomer, with azodiisobutyronitrile（AIBN）For initiator, with ethylene glycol dimethacrylate（EGDMA）For crosslinking agent,
It is prepared from by hydrothermal synthesis method.
Phenol-molecular sieve surface molecularly imprinted polymer employed in the application（SMIP）Material, it is special for phenol
Design, can specifically bind with phenol, it is adsorbed, and its preparation method is simple and easy to apply, prepares with low cost.Used
After in cigarette filter rod, examined through preliminary experiment, the material has preferable selection to the phenol material in cigarette mainstream flue gas
Property suction-operated, maximum reduction amplitude can preferably reduce harmful substance-phenol in main flume up to 30%, show
Preferable application value.
Brief description of the drawings
Fig. 1 is the fine binary compound filter candle structural representation of vinegar provided herein.
Embodiment
Explanation is further explained to the utility model below in conjunction with the accompanying drawings.
Embodiment
As shown in figure 1, the fine binary compound filter candle of the vinegar for reducing phenol in cigarette mainstream flue gas provided herein, bag
Include filter core 1, the interior integument 2 being wrapped on filter core and outer casing 3；Wherein filter core 1 is binary composite filter element, by acetate fiber
Section 1（a）Be loaded with phenol-molecular sieve surface molecularly imprinted polymer（SMIP）The acetate fiber section 1 of material（b）It is uniform alternate
It is bonded.
The acetate fiber section 1（b）It is by by phenol-molecular sieve surface molecularly imprinted polymer（SMIP）Material is uniform
