Abstract
The utility model discloses a polyacrylonitrile group activated carbon fiber concentric core ternary composite filter trip. The polyacrylonitrile group activated carbon fiber concentric core ternary composite filter trip is composed of first cellulose acetate fiber element sections which are packaged by outer layer molding papers and are connected with each other in sequence, concentric filter element sections and second cellulose acetate fiber element sections. The concentric filter element sections are cellulose acetate fiber concentric filter element sections. A concentric inner core made of the polyacrylonitrile group activated carbon fiber is arranged inside each concentric filter element section. By means of the adoption of the ternary composite filter trip which is made of cellulose acetate fiber element sections and the cellulose acetate fiber element sections with the concentric inner core made of the polyacrylonitrile group activated carbon fiber, the concentric core ternary composite filter trip can effectively reduce the tar content of cigarettes and achieve selective and efficient absorption of harmful ingredients of the cigarettes, such as benzo (a) pyrene, volatile aldoketones, phenol, hydrogen cyanide (HCN) and tobacco-specific nitrosamines, thus being green and environment-protecting and having no additional poisons. Due the fact that dose is few and efficiency is high, the harm of human body can be reduced and the taste of the cigarettes can be guaranteed to the greatest extent at the same time. Therefore, the polyacrylonitrile group activated carbon fiber concentric core ternary composite filter trip has wide application prospects in the field of reducing harm-reduction and tar reduction of the cigarettes.
Description
Technical field
The present invention relates to technical field of cigarettes, be specifically related to a kind of polyacrylonitrile radical active carbon fiber concentric ternary composite filter tip.
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), enter human body with flue gas and work the mischief when suction.Cigarette filter can stop these materials to enter human body to a certain extent.
Since first came out in nineteen thirty as the cigarette filter of adsorbent filtering medium with cotton in the world, through people's research and extension, filter tip cigarette output had accounted for more than 73% of world's cigarette total output at present, and developed country reaches more than 95%.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.
Chinese patent application 200710087127.1 announced 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 main flume; A kind of filter tip (Chinese patent application 03811336.8) has been invented by Switzerland Philip Morris, and this filter tip contains the fiber of a branch of energy loaded particle thing, bead or powder, helps reduce flue gas composition.ZL200820081632.5 has announced a kind of tri compound mouth rod, is comprised of two sections acetate fiber filter cores and one section space, and the tealeaves particle between the space after filling active carbon or pulverizing plays the effect to harmful substances in flue gas absorption.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, polarity is low, active conjugation site is few; adsorption efficiency to some harmfulness compositions in flue gas is undesirable; and; in mouth rod machining process; add particle or pulverous adsorbent, easily cause airborne dust, also exist adsorbent to fill the problems such as even not in filter tip.
The utility model content
Goal of the invention: for the deficiencies in the prior art, the purpose of this utility model is to provide a kind of polyacrylonitrile radical active carbon fiber concentric ternary composite filter tip, the harmful substance that produces in flue gas during efficient selective absorption cigarette smoking, do not affecting in 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:
A kind of polyacrylonitrile radical active carbon fiber concentric ternary composite filter tip, the first acetate fiber filter core section, coaxial filter core section and the second acetate fiber filter core section that connect successively of being wrapped up by outer forming paper form; Described coaxial filter core section is the coaxial filter core section of acetate fiber, is provided with the coaxial inner core of polyacrylonitrile radical active carbon fiber in coaxial filter core section.
The strip polyacrylonitrile radical active carbon fiber bar that described coaxial inner core is cut into by the polyacrylonitrile radical active carbon fiber felt.
The thickness of described polyacrylonitrile radical active carbon fiber felt is 2～5mm, and the width of cutting rear polyacrylonitrile radical active carbon fiber bar is 1～3mm.
The described length that is enclosed with the coaxial filter core section of the coaxial inner core of polyacrylonitrile radical active carbon fiber is 6～10mm.
Be equipped with the internal layer forming paper on described the first acetate fiber filter core section, coaxial filter core section and the second acetate fiber filter core section.
Beneficial effect: compared with prior art, the utlity model has following characteristics: make ternary composite filter tip by adopting acetate fiber filter core section to combine with the acetate fiber filter core section with the coaxial inner core of polyacrylonitrile radical active carbon fiber, can carry out efficient adsorption to benzo [a] pyrene, volatile aldehyde ketone, phenol, HCN; Environmental protection is poisoned without additional, because amount is few efficient, has reduced the harm of cigarette to human body in cigarette not affecting in the aesthetic quality; Falling burnt field at Harm reduction techniques has broad application prospects.
Description of drawings
Fig. 1 is the structural representation of polyacrylonitrile radical active carbon fiber concentric ternary composite filter tip.
The specific embodiment
Below in conjunction with concrete accompanying drawing, the utility model is described further.
As shown in Figure 1, polyacrylonitrile radical active carbon fiber concentric ternary composite filter tip, in the outer forming paper of this mouth rod, be enclosed with three kinds of filter core sections, be wherein the first acetate fiber filter core section 3 near the pipe tobacco end, middle one section is to have the coaxial filter core section 2 of the coaxial inner core 4 of polyacrylonitrile radical active carbon fiber, and the second acetate fiber filter core section 1 of close mouth end; The main material of coaxial filter core section 2 is acetate fiber, axially has the coaxial inner core 4 of polyacrylonitrile radical active carbon fiber, the coaxial inner core 4 of polyacrylonitrile radical active carbon fiber is cut by the polyacrylonitrile radical active carbon fiber felt and into strips, the thickness of felt is 2～5mm, the width of polyacrylonitrile radical active carbon fiber bar is 1～3mm, and nitric acid dousing 0.5～1h that carbon fiber felt used rolls front use 1～3mol/L processes.The length of coaxial filter core section 2 is 6～10mm.
Polyacrylonitrile radical active carbon fiber concentric ternary composite filter tip of the present utility model, make ternary composite filter tip by adopting acetate fiber filter core section to combine with the acetate fiber filter core section with the coaxial inner core of polyacrylonitrile radical active carbon fiber, can carry out efficient adsorption to benzo [a] pyrene, the short cancer molecule of volatile aldehyde ketone, phenol, HCN; Environmental protection is poisoned without additional, because amount is few efficient, has reduced the harm of cigarette to human body in cigarette not affecting in the aesthetic quality; Falling burnt field at Harm reduction techniques has broad application prospects.
