Abstract
The utility model discloses a binary composite filtering rod capable of selectively reducing volatile organic compounds in main stream smoke. The composite filtering rod comprises a filter element and an inner wrapping layer and an outer wrapping layer which are wrapped around the filter element sequentially, the filter element is a binary composite filter element which is composed of cellulose acetate fiber sections and composite sections composed of cellulose acetate fibers and particles made of chitosan-modified carbon mesoporous materials, and the cellulose acetate fiber sections and the composite sections are arranged at intervals. Compared with the prior art, the filtering rod has the advantages that the binary composite structure is adopted, and the composite sections which are arranged at intervals with the cellulose acetate fiber sections and composed of the cellulose acetate fibers and the particles made of the chitosan-modified carbon mesoporous materials are used for effectively and selectively reducing over 35% of five kinds of the volatile organic compounds, such as 1,3-butadiene, isoprene, benzene, methylbenzene and vinyl cyanide, in the main stream smoke of cigarettes, so that the danger of the cigarettes is reduced, and the original taste and the smoking quality of the cigarettes are kept. By the aid of the two outer wrapping layers which are wrapped around the filter element, the structure of the binary composite filtering rod is stable.
Description
Technical field
The utility model relates to the filter stick of making cigarette filter, especially a kind of binary compound filter candle that reduces volatile compound in the cigarette smoke.
Background technology
Contain a large amount of VOC (VOC) in the cigarette mainstream flue gas, this class material is gaseous state or liquid state at normal temperatures, and is generally poisonous, and penetrating odor is arranged.In 44 kinds of cigarette smoke harmful components listing in the Hoffmann list, volatile organic component has 5 kinds, is respectively 1,3-butadiene, isoprene, benzene, toluene, propylene are fine, wherein benzene is human carcinogen's thing, and 1,3-butadiene, isoprene and propylene are fine to be the possible carcinogenic substance of human body.
Existing cigarette filter great majority are single acetate fiber monobasic filter stick, the harmful substance that reduces in the cigarette smoke had certain effect, also have at present and in filter stick, add some functional materials and reduce harmful components in the flue gas, disclose the cigarette composite filter tip that a kind of modified absorbing material granules is made as patent CN101396170, can improve the cigarette smoking quality and can remove the part harmful components.The amido material that patent CN201108028 makes surfactant adds in the vinegar fibre and obtains the binary composite filter tip, alternatively reduces volatile carbonyl compound harmful in the cigarette smoke.CN 201869771 U disclose a kind of alternative binary compound filter candle that reduces phenol burst size in the cigarette mainstream flue gas, and amplitude can reach more than 25%.But existing these filter sticks are harmful VOC in the selectivity reducing cigarette fume (1,3-butadiene, isoprene, benzene, toluene, propylene are fine) simultaneously all.
The utility model content
At the above-mentioned problems in the prior art, the utility model patent provides the binary compound filter candle of VOC in the firm selective reduction main flume of a kind of structure, this filter stick can selectivity reducing cigarette fume in 5 kinds of VOCs, and can keep the original taste of cigarette and sucking quality.
The technical scheme that its technical problem that solves the utility model adopts is:
The selective binary compound filter candle that reduces VOC in the main flume is characterized in that: described composite filter comprises filter core and is wrapped in interior integument, outer wrapping layer on the filter core successively; Described filter core is the binary composite filter element, and described binary composite filter element is to be made of the composite log that the acetate fiber section that arranges at interval and acetate fiber add chitin modified carbon mesoporous material particle.
Further, acetate fiber adds the composite log of chitin modified carbon mesoporous material particle by diffusing being spread across on the acetate silk of granular chitin modified carbon mesoporous material formed.
Compared with prior art, the beneficial effects of the utility model are:
The utility model filter stick adopts the binary composite construction, utilize composite log that acetate fiber with the setting of acetate fiber spacer segment adds chitin modified carbon mesoporous material particle effectively can the selectivity reducing cigarette main flume in VOC in 5, as: 1,3-butadiene, isoprene, benzene, toluene, propylene are fine, amplitude reaches more than 35%, and then reach the purpose that reduces cigarette harmfulness, and can keep the original taste of cigarette and sucking quality.The integument of outer two-layer parcel filter core makes the structure of the utility model binary compound filter candle more firm.
Description of drawings
Fig. 1 is the structural representation of the utility model binary compound filter candle.
The sequence number of primary clustering explanation in the accompanying drawing:
Integument, 4-outer wrapping layer, 5-acetate fiber section, 6-acetate fiber add the composite log of chitin modified carbon mesoporous material particle in the granular chitin modified carbon mesoporous material of 1-, 2-filter core, the 3-.
The specific embodiment
As shown in Figure 1, the binary compound filter candle of VOC comprises filter core 2 and is wrapped in interior integument 3, outer wrapping layer 4 on the filter core 2 successively in the utility model selectivity reducing cigarette main flume; Interior integument 3 is wrapped on the binary composite filter element 2, and outer wrapping layer 4 is wrapped on the interior integument 3.Described filter core 2 is the binary composite filter element, and described binary composite filter element is to be made of the composite log 6 that the acetate fiber section 5 that arranges at interval and acetate fiber add chitin modified carbon mesoporous material particle.
In the utility model, the composite log 6 that acetate fiber adds chitin modified carbon mesoporous material particle forms by loosing to be spread across on the acetate silk with granular chitin modified carbon mesoporous material 1.Employed chitin modified carbon mesoporous material is about to the end product that 0.1-0.2 g shitosan, 1.0-3.0 g mesoporous carbon obtain after the mechanical agitation 2-4 h reaction in 0.01-0.05 mol/L hydrochloric acid solution.Now the cigarette with acetate fiber monobasic filter stick under the identical working condition is control sample, adopts shown in the following subordinate list of result of 5 kinds of VOCs in the binary compound filter candle selectivity reducing cigarette main flume of the utility model structure.
The chitin modified carbon mesoporous material of subordinate list reduces the result of 5 kinds of VOC burst sizes.
Above embodiment only is explanation technological thought of the present utility model; can not limit protection domain of the present utility model with this; every according to the technological thought that the utility model proposes, as to do on the technical scheme basis any change all falls within the utility model protection domain.
