Abstract
The utility model relates to a kind of nitrogen-doped nanometer carbon pipe composite cigarette filter tip.This filter tip is mainly made up of filtering bodies and outsourcing paper web, and wherein said filtering bodies part is divided into again two-stage structure, and one section is the nitrogen-doped nanometer carbon pipeline section of nearly cigarette section, and another section is the cellulose acetate segment of nearly mouth section.Described nitrogen-doped nanometer carbon pipeline section is made up of nitrogen-doped nanometer carbon pipe and acetate silk, and described external packing paper web is coated on filtering bodies outside and forms described cigarette filter.The utility model nitrogen-doped nanometer carbon pipe composite cigarette filter tip can less affect cigarette mouthfeel in, effectively adsorb the harmful substance in flue gas, reduce the impact of harmful substances in flue gas on health.
Description
Technical field
The utility model relates to a kind of nitrogen-doped carbon nanometer pipe composite cigarette filter tip, for reducing the oxious component in flue gas.
Background technology
In the main flume producing in cigarette burning process, contain a large amount of chemical substances, comprise tar, nicotine, ammonia (NH3), hydrogen cyanide (HCN), low molecule aldehyde material (acetaldehyde, propionic aldehyde, crotonaldehyde etc.) and volatile gas (VOC) etc., after these chemical substances are mutual miscible, enter in smoker's body by cigaratte filter rear section with aerocolloidal form.The effect of cigaratte filter is mainly that mutual collision aggegation frequency and the suction-operated by increasing smoke particles reduces the harmful components that enter human body.
At present, commercial cigarettes adopts acetate silk as filter tip conventionally, for further reducing volatility, half volatile organic poison, in some cigarette filters, add part active component, as porous activated carbon, facts have proved that porous activated carbon is removing in cigarette smoke in part harmful substance, also removed in the lump some aromatic compounds in flue gas and cause fragrance deficiency, affect cigarette local flavor; Chitin (license notification number CN200941810Y), the young powder of tea (number of patent application 201210540305.2) are as cigarette filter, the taste of its active component self is compared with malleable cigarette local flavor, therefore add suitable active component in effectively adsorbing harmful substances from flue gases, the less cigarette filter that affects cigarette mouthfeel and quality becomes this area technical problem in the urgent need to address.
Utility model content
The utility model discloses a kind of nitrogen-doped carbon nanometer pipe composite cigarette filter tip, be intended to overcome that cigaratte filter in prior art exists affects cigarette mouthfeel, can not effectively adsorb the drawback of the harmful substance in flue gas simultaneously, the nitrogen-doped carbon nanometer pipe composite cigarette filter tip of the utility model design, not only the adsorbance of harmful substances from flue gases is improved greatly, effectively reduce the harm to health, and can keep the original quality of cigarette and fragrance.
Technical solutions of the utility model are achieved in that
A kind of nitrogen-doped carbon nanometer pipe composite cigarette filter tip, formed by filtering bodies, outsourcing paper web, it is characterized in that: described filtering bodies is two-stage structure, comprise the nitrogen-doped nanometer carbon pipeline section of nearly pipe tobacco section and the cellulose acetate segment of nearly mouth section, the nitrogen-doped nanometer carbon pipeline section of described nearly cigarette section is made up of nitrogen-doped nanometer carbon pipe and acetate silk, nitrogen-doped nanometer carbon pipe is evenly distributed on described acetate silk, and outsourcing paper web is coated on the described cigaratte filter of the outer formation of filtering bodies.
The length of described nitrogen-doped nanometer carbon pipeline section is 1.0-2.2 centimetre.
Described nitrogen-doped nanometer pipeline section, the addition of nitrogen-doped nanometer carbon pipe is 0.5-2mg/mm.
Described nitrogen-doped nanometer carbon pipeline section, the mass ratio of nitrogen and CNT is: 0.1-1.
The utlity model has following advantage and good effect:
1. nitrogen-doped nanometer carbon pipe good stability, specific area is large, surface pore compound with regular structure is complete, simultaneously owing to introducing more avtive spot after nitrating on surface, have the absorption of aroma substance in cigarette few, to the high feature of Selective adsorption of particle tar material and aldehydes matter etc. in smog.Less affect cigarette local flavor in, effectively reduce tar material and harmful substance contents in smog, thereby protect better smoker's health.
2. nitrogen-doped nanometer carbon pipe is to no toxic biological, and with chemical bonding, on acetate silk surface, difficult drop-off, can make desirable filter tip composite.
Brief description of the drawings

Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is elaborated.
A kind of nitrogen-doped carbon nanometer pipe composite cigarette filter tip, structure as shown in Figure 1, is made up of filtering bodies 2, outsourcing paper web 1.Described filtering bodies 2 is two-stage structure, comprises the nitrogen-doped nanometer carbon pipeline section 21 of nearly pipe tobacco section and the cellulose acetate segment 22 of nearly mouth section, and the nitrogen-doped nanometer carbon pipeline section 21 of described nearly cigarette section, is made up of nitrogen-doped nanometer carbon pipe 211 and acetate silk 212.
As shown in Figure 2, nitrogen-doped nanometer carbon pipe 211 is evenly distributed on described acetate silk 212.
Outsourcing paper web 1 is coated on outside filtering bodies 2, forms described cigaratte filter.
Wherein: the length of nitrogen-doped nanometer carbon pipeline section is 1.0-2.2 centimetre; The addition of nitrogen-doped nanometer carbon pipe is 0.5-2mg/mm; The nitrogen of nitrogen-doped carbon nanometer pipe section and the mass ratio of CNT are: 0.1-1.
When smoking, light cigarette, flue gas is after nitrogen-doped nanometer carbon pipeline section 21, due to nitrogen-doped carbon nanometer pipe good stability, specific area is large, and surface pore compound with regular structure is complete, simultaneously owing to introducing more avtive spot after nitrating on surface, particle tar material in smog and the adsorbance of aldehyde material are improved greatly, can less affect cigarette local flavor in, effectively reduce harmful substances from flue gases content; Again through the cellulose acetate segment 22 of nearly mouth section, further filtering out harmful matter, thus protect better smoker's health.
