Problems solved by technology

The phenolic compounds in cigarette smoke mainly come from the cracking of polyphenols in tobacco leaves. Catechol in smoke has auxiliary carcinogenic effect, and phenolic substances have a relatively strong stimulating effect on the respiratory mucosa, which affects the smoking of cigarettes. suction quality

Embodiment 1

[0023] The total concentration of surfactant in the solution is 0.04-0.4mol / l to prepare a surfactant aqueous solution, and then the carbon nanotubes (the length to diameter ratio of carbon nanotubes is 10 3 -10 6 ) Adding to the aqueous solution of surfactant and ultrasonic to form a uniformly dispersed and stable suspension to obtain the finished additive product.

Embodiment 2

[0025] First prepare a 0.1 mol / l sodium lauryl sulfate solution, add multi-walled carbon nanotubes in an amount of 10.0 mg / ml, and ultrasonically disperse them uniformly. The added amount of carbon nanotube additives is 15% of the weight of the tobacco leaf. According to the weight of the tobacco leaf, a certain amount of multi-walled carbon nanotube / sodium lauryl sulfate solution is mixed with the pre-prepared additive flavor, and sprayed on the tobacco leaf. After being rolled into cigarettes, ignited and analyzed the target chemical components in mainstream smoke. Compared with control cigarettes, tar was reduced by 3.9%, benzo[a]pyrene was reduced by 8.2%, phenol was reduced by 3.8%, and catechol was reduced by 4.7%. .

Embodiment 3

[0027] First prepare a 0.1 mol / l sodium dodecylbenzene sulfonate solution, add multi-walled carbon nanotubes in an amount of 10.0 mg / ml, and make it uniformly dispersed by ultrasound. The added amount of carbon nanotube additives is 15% of the weight of the tobacco leaf. %, according to the weight of the tobacco leaf, a certain amount of multi-walled carbon nanotube / sodium dodecylbenzene sulfonate solution is mixed with the pre-prepared additive flavor, and sprayed on the tobacco leaf. After being rolled into cigarettes, ignited and analyzed the target chemical components in mainstream smoke. Compared with control cigarettes, tar was reduced by 3.4%, benzo[a]pyrene was reduced by 6.2%, phenol was reduced by 3.0%, and catechol was reduced by 3.5%. .

Abstract

The invention relates to a cigarette additive and cigarette prepared by the additive. The additive can lower the tar contents in cigarette flue gas and can selectively absorb harmful substances such as polycyclic aromatics, phenols and the like in cigarette flue gas. The additive is carbon nanometer pipe preparation dispersed in water solution of surface active agent. The preparation is taken as cigarette cut tobacco additive and is sprayed on tobacco leaves in the cigarette production material feeding technique process according to 1 to 25% of the weight of the cut tobacco, and carbon nanometer pipes are evenly and dispersedly absorbed on the surface of the cut tobacco after silk drying processing. The additive can remove 6.2-38.8% of polycyclic aromatics such as Benzo(a)pyrene and the like and 3.0 to 28.3% of carbolic acid and catechol in cigarette main flow flue gas, and also can lower the tar contents in flue gas for 3.4 to 20.4%, and the original color and flavor of cut tobacco are not changed basically.

Description

Technical field [0001] The invention belongs to the field of cigarette processing, and in particular relates to a cigarette additive for reducing harmful components in cigarette smoke and cigarettes made therefrom. technical background [0002] At this stage, the tobacco industry is facing multiple pressures from the World Health Organization (WHO) and the "Tobacco Control Framework Treaty". On the other hand, with the continuous improvement of living standards and quality of life, the contradiction between smoking and health has become increasingly prominent. The requirements for sex are also getting higher and higher. Reducing the amount of tar in cigarette smoke, especially reducing the harmful components in smoke, is an important task facing the tobacco industry. [0003] Cigarette burning is a very complex reaction. There are many harmful components in mainstream smoke that have carcinogenic or synergistic carcinogenic effects, such as polycyclic aromatic hydrocarbons represen...
