Problems solved by technology

However, because the composition of Chinese herbal medicine is very complex, adding it to shredded tobacco and directly participating in the combustion is likely to affect the taste of the smoke, and sometimes increase the content of other harmful components
However, there are relatively few reports on adding herbal preparations such as Chinese herbal medicines to cigarette filters, and most of the reports apply herbal preparations such as Chinese herbal medicines and other materials to cigarette filters by simply mixing and adding them together, which is difficult to achieve. Uniformity of compositional structure throughout the additive

Embodiment 1

[0051] Add 10.1 grams of dimethylaminoethyl methacrylate into a round-bottomed flask containing 8.0 milliliters of benzyl bromide (or one of bromoethane, bromobutane, or hexadecane bromide), and add 20.0 milliliters of acetone, at 30 Reaction at ℃ for 12 hours to prepare quaternary ammonium salt type polymerizable monomer dimethylbenzylmethacryloyloxyethylammonium bromide (or dimethylethylmethacryloyloxyethylammonium bromide, dimethyl One of butyl methacryloyl oxyethyl ammonium bromide and dimethyl hexadecyl methacryloyl oxyethyl ammonium bromide). The structures of the prepared quaternary ammonium salt type polymerizable monomers were all proved by infrared spectrum characterization analysis.

[0052] Among them, the infrared spectrum characteristic signal peaks of dimethyl benzyl methacryloxyethyl ammonium bromide: 3004, 1722, 1634, 959cm -1 ; The infrared spectrum characteristic signal peak of dimethyl ethyl methacryloyloxyethyl ammonium bromide: 1720, 1634, 959cm -1 ; Th...

Embodiment 2

[0055] Four kinds of quaternary ammonium salt type polymerizable monomers (0.02mol) prepared in Example 1 were added respectively in the polymerization tube containing distilled water, and an appropriate amount of potassium persulfate aqueous solution (mass percentage concentration was 1%) was added thereto, The four kinds of quaternary ammonium salt type polycations were respectively prepared by passing nitrogen protection and reacting at 70° C. for 6 hours. The structure of the prepared polycation is proved by characterization analysis such as infrared spectrum.

[0056] Among them, the infrared spectrum characteristic signal peaks of polydimethylbenzylmethacryloxyethylammonium bromide: 3385, 1727, 1149cm -1 ; The infrared spectrum characteristic signal peak of polydimethylethylmethacryloxyethylammonium bromide: 3373, 1728, 1456cm -1 ; The infrared spectrum characteristic signal peak of polydimethylbutylmethacryloxyethyl ammonium bromide: 3447,1728,1467cm -1 ; The infrared...

Embodiment 3

[0059] Add 30.0 ml of acrylic acid, 130.0 ml of vinyl acetate, 3.2 g of mercury acetate, a small amount of copper acetate and 0.3 ml of concentrated sulfuric acid into a three-necked flask, stir at 50°C, and react for 3 hours to prepare acryloxy vinyl propionate . The structure of the prepared product was determined by characterization analysis such as infrared spectroscopy.

[0060] After infrared spectrum characterization analysis, the prepared product has infrared spectrum characteristic signal peaks of acryloyloxy vinyl propionate: 3100, 1759, 1731, 1647, 1409, 1058, 985cm -1 , indicating the successful preparation of vinyl acryloxypropionate.

Abstract

The invention discloses a polyanion composite material for reducing benzo (a) pyrene contained in cigarette smoke and a preparation method. The polyanion composite material is alternately provided with polycations and functional polycations on the surface of a porous material, and a start layer arranged on the surface of the porous material is a polycation layer; and the polyanion composite material can be used as an additive inside a cigarette filter and is used for preparing the cigarette filter. The polyanion composite material is used for the cigarette filter and can effectively reduce the content of the benzo (a) pyrene contained in the cigarette smoke; and in addition, compared with commercial cigarettes with same specifications, the content of the benzo (a) pyrene contained in the smoke of a sampling cigarette containing the polyanion composite material is reduced by 15-45 percent.

Description

technical field [0001] The invention relates to the technical field of cigarette tar reduction and harm reduction, in particular to a polyanion composite material for reducing the content of benzo[a]pyrene in cigarette smoke and a preparation method thereof. Background technique [0002] Since the 1950s, society has paid more and more attention to smoking and health issues, especially after the launch of the "Framework Convention on Tobacco Control" formulated by the World Health Organization (WHO) and signed by governments of member states, to reduce the impact of tobacco products on The harm to human health has become an inevitable trend in the development of the international cigarette industry. Polycyclic aromatic hydrocarbons are the most important carcinogens in cigarette smoke, among which benzo[a]pyrene has the strongest carcinogenic activity. Therefore, how to effectively reduce the content of polycyclic aromatic hydrocarbons in cigarette smoke, especially the cont...
