Abstract
The utility model discloses a ternary composite filter tip of activated carbon fibres. The ternary composite filter tip of the activated carbon fibres is composed of a first common filter element segment, an activated carbon fibre filter segment and a second common filter segment, wherein the first common filter segment, the activated carbon fibre filter segment and the second common filter segment are covered by an outer layer forming paper and are connected in sequence. The activated carbon fibre filter segment is added to the ternary composite filter tip of the activated carbon fibres, and can carry out selective efficient absorption on benzo [a] pyrene, volatile aldehyde ketone series, phenol, hydrogen cyanide (HCN) and other harmful ingredients of cigarettes. The ternary composite filter tip of the activated carbon fibres is environment-friendly and has no additional poison. Due to the fact that the ternary filter tip of the activated carbon fibres is small in quantity and efficient, the inner sensory quality of the cigarettes is not affected, and at the same time, harm on human bodies from the cigarettes is reduced. The ternary filter tip of the activated carbon fibres is wide in application prospect in the filed of 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 NACF 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.As 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.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, it is undesirable to the harmful micromolecular adsorption efficiency of aromatic aldehyde equiconjugate polarity, and the suction type of harmful substance take physical absorption as main, has therefore been limited the raising of its adsorption efficiency.
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 NACF 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 NACF ternary composite filter tip, the first common filter core section, NACF filter core section and the second common filter core section that connect successively of being wrapped up by outer forming paper form.
Described NACF filter core section is base materials employed is polyacrylonitrile-radical or viscose-based active carbon fiber.
The length of described NACF filter core section is 2～5mm.
The described first common filter core section (1) is acetate fiber or polypropylene fibre filter core.
The described second common filter core section (3) is acetate fiber or polypropylene fibre filter core.
Beneficial effect: compared with prior art, the utlity model has following characteristics: by add NACF filter core section in the filter core section, 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.
Description of drawings
Fig. 1 is the structural representation of NACF 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, the NACF ternary composite filter tip, the first common filter core section 1, the common filter core section 3 of NACF filter core section 2 and second that connect successively of being wrapped up by outer forming paper form.NACF filter core section 2 length are 2～5mm, and base materials employed is polyacrylonitrile-radical or viscose-based active carbon fiber.The first common filter core section 1 and the second common filter core section 3 are acetate fiber or polypropylene fibre filter core.
NACF ternary composite filter tip of the present utility model by add NACF filter core section in the filter core section, 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.
