Abstract
The utility model discloses a binary composite filter stick capable of selectively reducing hydrocyanic acid emission amount in cigarette smoke. The composite filter stick comprises a filter element (1) as well as an inner coating layer (2) and an outer coating layer (3) which are sequentially coated on the filter element. The composite filter stick is characterized in that: the filter element (1) is of a binary composite filter element and consists of acetate fiber sections (1a) which are spaced at intervals and charging sections (1b) composed of acetate fibers and water-holding materials, wherein the water-holding materials in the charging sections are obtained by porous activated aluminum oxide treated by polyvinyl alcohol alkali solution or by porous hydrophilic vinyl polymer HW-65F treated by carboxymethyl starch solution. Compared with the prior art, the binary composite filter stick has the remarkable characteristic of selectively reducing the harmful hydrocyanic acid in the cigarette smoke as high as above 30 percent, so as to achieve the purpose of reducing the cigarette harmfulness.
Description
Technical field
The utility model relates to a kind of filter stick that is used to make cigarette filter, especially a kind of alternative binary compound filter candle that reduces hydrogen cyanide burst size in the cigarette mainstream flue gas.
Background technology
At present, cigarette filter mostly is single acetate fiber monobasic filter stick greatly, and the harmful substance that reduces in the cigarette smoke is had certain effect.Growing interest along with smoking and health problem, countries in the world are more and more paid attention to the exploitation of filter tip material and filter structures cigarette, the purpose that some functional elements reach lowering harm and decreasing coking has appearred adding in filter stick, 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.The highly basic material that patent CN200920223706.9 makes the porous hydroxyapatite of chlorination trimethylamine groups acethydrazide modification adds in the vinegar fibre and obtains the binary composite filter tip, the alternative hydrogen cyanide burst size that reduces in the cigarette mainstream flue gas.Therefore but the highly basic material that relates in this patent does not possess water holding capacity preferably, to the reduction effect of HCN in the cigarette smoke less stable with standing time.
Summary of the invention
A kind of alternative binary compound filter candle that reduces hydrogen cyanide burst size in the cigarette mainstream flue gas that the purpose of this utility model is developed at existing problem in the above-mentioned prior art just, it can the selectivity reducing cigarette main flume in hydrogen cyanide, and amplitude reaches more than 30%.
The purpose of this utility model is achieved through the following technical solutions:
The alternative binary compound filter candle that reduces hydrogen cyanide burst size in the cigarette smoke of the present utility model comprises filter core and is wrapped in interior integument on the filter core successively, the outer wrapping layer, wherein: described filter core is the binary composite filter element, it is to be made of with the feeding section that water-keeping material constitutes acetate fiber section that is provided with at interval and acetate fiber, the water-keeping material that water-keeping material that the water-keeping material in the wherein said feeding section obtains for the porous active aluminium oxide that adopts the polyvinyl alcohol aqueous slkali to handle or the porous hydrophilic sex ethylene based polyalcohol HW-65F that adopts the processing of CMS aqueous slkali obtain.
In the utility model, described water-keeping material is sprayed on the acetate silk by the method for spilling dispersion of loosing.
The cigarette that the cellulose acetate filter rod of prior art makes under identical working condition is a control sample, with adopt the polyvinyl alcohol aqueous slkali to handle the porous active aluminium oxide in the utility model to make binary compound filter candle and make cigarette sample and compare, the measurement result of hydrogen cyanide burst size is as shown in table 1 below in its main flume.

(addition 40mg/cig)
The beneficial effects of the utility model are as follows:
Outstanding feature of the present utility model is the hydrogen cyanide burst size in can the selectivity reducing cigarette main flume, and amplitude reaches more than 30%, thereby reaches the purpose of effective reduction cigarette harmfulness.
Description of drawings
Accompanying drawing is a structure chart of the present utility model.
The specific embodiment
The utility model is further described below in conjunction with accompanying drawing:
As shown in the figure: the alternative binary compound filter candle that reduces hydrogen cyanide burst size in the cigarette smoke of the present utility model comprises filter core 1 and is wrapped in interior integument 2 on the filter core successively, outer wrapping layer 3, wherein: described filter core 1 is the binary composite filter element, it is to be made of with the feeding section 1b that water-keeping material constitutes acetate fiber section 1a that is provided with at interval and acetate fiber, the water-keeping material that water-keeping material that the water-keeping material in the wherein said feeding section obtains for the porous active aluminium oxide that adopts the polyvinyl alcohol aqueous slkali to handle or the porous hydrophilic sex ethylene based polyalcohol HW-65F that adopts the processing of CMS aqueous slkali obtain.
