Problems solved by technology

It is worth noting that on the one hand, carbon nanotube materials are expensive, the preparation process is complicated, and it is not easy to promote and apply industrially; on the other hand, they do not have significant adsorption and removal effects on harmful components such as hydrocyanic acid, crotonaldehyde, ammonia, and NNK.
In addition, the safety of its use has yet to be further determined

Embodiment 1

[0018] Titanium dioxide nanotubes are used as the additive material for the binary composite filter, sieved to 50-300 mesh particles, and the addition amount is 20mg / cig. The cigarette without any filter modification material is used as the control sample, and it is smoked according to the standard Smoking conditions Carry out a cigarette smoking test on a smoking machine, and follow the standards YC / T255-2008, YC / T254-2008, GB / T21130-2007, GB / T 23228-2008, YC / T 377-2010 and YC / T 403 -In 2011, we carried out the detection of phenol, crotonaldehyde, benzopyrene, NNK, ammonia and hydrocyanic acid release in mainstream smoke. The analysis results are shown in Table 1.

Embodiment 2

[0020] Use cuprous oxide doped titanium dioxide nanotubes as a binary composite filter additive material, sieving to 50-300 mesh particles, the addition amount is 10mg / cig. The cigarette without any filter modification material is used as a control Samples, in accordance with the standard smoking conditions on the cigarette smoking test, and in accordance with the standards YC / T255-2008, YC / T254-2008, GB / T21130-2007, GB / T 23228-2008, YC / T 377-2010 In conjunction with YC / T 403-2011, conduct mainstream smoke detection of phenol, crotonaldehyde, benzopyrene, NNK, ammonia and hydrocyanic acid release. The analysis results are shown in Table 1.

Embodiment 3

[0022] The zirconium-doped titanium dioxide nanotubes are used as the additive material for the binary composite filter, and they are sieved to 50-300 mesh particles, and the addition amount is 30mg / cig. The cigarette without any filter modification material is used as the control sample. Carry out the cigarette smoking test on the smoking machine according to the standard smoking conditions, and follow the standards YC / T255-2008, YC / T254-2008, GB / T21130-2007, GB / T 23228-2008, YC / T 377-2010 and YC / T 403-2011 Detects the release of phenol, crotonaldehyde, benzopyrene, NNK, ammonia and hydrocyanic acid in mainstream smoke. The analysis results are shown in Table 1.

Abstract

The invention discloses a filter tip capable of reducing the releasing amount of harmful ingredients of mainstream cigarette smoke. The filter tip comprises a titanium dioxide nano tube additive, wherein the content of an additive in each filter tip is 10-30 mg; the pore diameter of a titanium dioxide nano tube is in a range of 1.5-30 nm. The titanium dioxide nano tube additive is a compound of one or more than two of the titanium dioxide nano tube, a cuprous oxide coped titanium dioxide nano tube, an iron oxide doped titanium dioxide nano tube, an aluminum doped titanium dioxide nano tube, a zirconium doped titanium dioxide nano tube and a boron doped titanium dioxide nano tube according to any ratio. With the adoption of the filter tip, the releasing amount of the harmful ingredients including hydrocyanic acid, benzopyrene, phenol, crotonaldehyde, ammonia and NNK (nitrosamine) in the mainstream smoke can be reduced by more than 30%.

Description

Technical field: [0001] The invention belongs to the technical field of harm reduction and coke reduction in the tobacco industry, and specifically relates to a filter that can reduce the release of harmful components in mainstream cigarette smoke. Background technique: [0002] At this stage, the tobacco industry is facing multiple pressures from the World Health Organization 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, and the safety requirements for cigarettes Increasingly, improving the safety of cigarettes and reducing the release of harmful components in cigarette smoke are the development direction of international cigarette technology and an inevitable demand for the development of Chinese cigarettes. The release of seven harmful components in cigarettes: carbon monoxide, hydrocyanic acid, phenylpropiony...
