Description

A kind of paper-vinegar binary compound filter candle for reducing ammonia of main stream smoke of cigarette

Technical field

The utility model belongs to cigarette filter rod manufacturing technology field, and in particular to one kind can reduce ammonia of main stream smoke of cigarette Paper-vinegar binary compound filter candle.

Background technology

With the continuous improvement of common people's health perception, smoking has become worldwide important class at present with health problem 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.

Ammonia is larger to health effect a kind of pernicious gas in cigarette mainstream flue gas, although existing part in the prior art For the research of sorbing material used in reduction ammonia of main stream smoke of cigarette, and certain technique effect is obtained, but with regard to practical application For, it is still necessary to the application with regard to new sorbing material and its in cigarette is further studied, so as to be cigarette quality Stable improve establishes good application foundation.

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 non-selective and harm reduction effect compared with For limited defect.

Aluminium dihydrogen tripolyphosphate is a kind of big solid acid of the weak and acid degree of acid strength, water is insoluble in, with layer structure. Study and thought, aluminium dihydrogen tripolyphosphate can carry out many physics and chemical bond and friendship with the amino molecule in gas phase Change, at present to aluminium dihydrogen tripolyphosphate to the existing part of theory research of the adsorption dynamics adsorption kinetics of ammonia.But it is existing for practical application Have in technology there is not yet preferably making an addition to such material in filter tip is used to adsorb, reduces ammonia of main stream smoke of cigarette release Amount, is especially used for relevant report prepared by filter stick by the material.

The content of the invention

The utility model purpose is the paper-vinegar for providing the ammonia being harmful in a kind of alternative reduction cigarette mainstream flue gas Binary compound filter candle, so as to be laid the foundation for the stable improvement of cigarette quality.

Technical solution adopted in the utility model is as described below.

A kind of paper-vinegar binary compound filter candle for reducing ammonia of main stream smoke of cigarette, the filter stick includes filter core, is wrapped in Interior integument and outer casing on filter core；Wherein filter core is binary composite filter element, by acetate fiber section and being coated with trimerization phosphorus The cellulose paper section of acid dihydride aluminum is uniformly alternate to be bonded.

Paper-vinegar the binary compound filter candle for reducing ammonia of main stream smoke of cigarette, with the conventional cigarette filter stick of 25mm length Exemplified by, the fibrous paper segment length for being coated with aluminium dihydrogen tripolyphosphate material is 15mm, and the coating weight of aluminium dihydrogen tripolyphosphate material is 20 ~ 30mg, specifically for example, 25mg.

Aluminium dihydrogen tripolyphosphate material described herein, prepares according to prior art, specifically for example passes through hydro-thermal Method is prepared from, and preparation process is specially：Aluminium hydroxide and water are mixed and added in reactor first, be heated with stirring to 90 DEG C ~ 100 DEG C, the phosphoric acid solution of certain molar weight is added, reaction obtains translucent thick liquid material after 1 hour；While hot by these materials It is put into 300 DEG C of Muffle furnaces, continues heat condensation 10 hours；Most afterwards through aquation, 100 DEG C dry, and grinding and sieving is trimerization Aluminium dihydrogen phosphate white powder.

The aluminium dihydrogen tripolyphosphate material, when being coated on cellulose paper material, its particle diameter is generally 40 ~ 60 Mesh.

In general, aluminium dihydrogen tripolyphosphate material employed in the application, its preparation method is simple and easy to apply, prepares cost It is cheap.By using it for preparing after composite cigarette filter stick, specific selectivity is shown to ammonia of main stream smoke of cigarette and is inhaled Attached effect.Determined through Preliminary detection, the utility model provides binary compound filter candle, can preferably reduce cigarette mainstream flue gas Middle ammonia burst size, reduction amplitude preferably realizes the purpose of reduction cigarette harmfulness, pushed away with certain up to 30% or so Wide application value.

Brief description of the drawings

Fig. 1 is paper provided by the utility model-vinegar binary compound filter candle structural representation.

Embodiment

Explanation is further explained to the utility model below in conjunction with the accompanying drawings.

Embodiment

As shown in figure 1, the paper for reducing ammonia of main stream smoke of cigarette-vinegar binary compound filter candle 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）With the cellulose paper section 1 for being coated with aluminium dihydrogen tripolyphosphate material（B）It is uniformly alternate to be bonded.

Prepared using hydrothermal synthesis method after aluminium dihydrogen tripolyphosphate material, crushed through 40 ~ 60 mesh, be spread evenly across cellulose After paper material, the fibre that filter stick regular size is herein described aluminium dihydrogen tripolyphosphate material is rolled into according to prior art The plain paper section 1 of dimension（B）.

To examine the technique effect of binary compound filter candle provided herein in reduction cigarette smoke in terms of ammonia content, Inventor has carried out further experiment detection, is briefly discussed below.

By taking the long binary compound filter candles of certain branch 100mm as an example, wherein conventional acetate fiber section 40mm, is coated with tripolyphosphate The fibrous paper segment length 60mm of dihydro aluminum, the particle diameter of aluminium dihydrogen tripolyphosphate material is 40-60 mesh, coating weight 100mg.

Under the same terms, the cigarette using the common cellulose acetate filter rod prepared by prior art as control sample, with added with The cigarette sample for the aluminium dihydrogen tripolyphosphate material binary compound filter candle that the present embodiment is provided be test sample, with certain brand into Exemplified by product cigarette, after using the suction of auto-pumping cigarette machine, ammonia of main stream smoke of cigarette and releasing content of coke tar are determined. Specific measurement result is as shown in the table：

。

It can be seen that using after binary compound filter candle provided by the utility model, released in tar from upper table testing result High-volume without in the case of significant change, ammonia of main stream smoke of cigarette burst size averagely reduces 30.8%.

In general, the utility model is directed to ammonia particular design contained in cigarette mainstream flue gas, to cigarette main flue There is ammonia in gas preferable selective absorption to act on, and can preferably reduce the harmful substance in main flume, thus tool There is certain application value.
