preparation example Construction

[0040] The preparation method embodiment 1 of the color-changing adsorption material for cigarette filters of the present invention adopts the following steps:

[0041] 1) Fully swell polyvinyl alcohol 1788 in water, and then heat it to fully dissolve to obtain a polyvinyl alcohol solution, add sodium chloride to the polyvinyl alcohol solution to dissolve, and obtain a water phase; in the water phase, polyvinyl alcohol The mass fraction is 0.6%, and the mass fraction of sodium chloride is 7%;

[0042] Mix divinylbenzene, ethyl acrylate and liquid paraffin evenly in a mass ratio of 30:70:150, then add initiator azobisisobutyronitrile (azobisisobutyronitrile and ethyl acrylate and divinylbenzene 2% of the total mass) mix uniformly to obtain the oil phase;

[0043] Add the water phase into a 250ml three-necked flask equipped with a stirrer, reflux condenser and thermometer, raise the temperature to 40°C, add the oil phase under stirring, the mass ratio of the oil phase to the wa...

Embodiment 2

[0046] The preparation method embodiment 2 of the color-changing adsorption material for cigarette filters of the present invention adopts the following steps:

[0047] 1) Fully swell polyvinyl alcohol 1788 in water, and then heat it to fully dissolve to obtain a polyvinyl alcohol solution, add sodium chloride to the polyvinyl alcohol solution to dissolve, and obtain a water phase; in the water phase, polyvinyl alcohol The mass fraction is 1.2%, and the mass fraction of sodium chloride is 10%;

[0048] Mix divinylbenzene, ethyl methacrylate, liquid paraffin, and toluene in a mass ratio of 20:80:40:80, and then add the initiator azobisisobutyronitrile (azobisisobutyronitrile accounts for methacrylic acid 1% of the total mass of ethyl ester and divinylbenzene) mixed uniformly to obtain an oil phase;

[0049] Add the water phase into a 250ml three-necked flask equipped with a stirrer, a reflux condenser and a thermometer, raise the temperature to 40°C, add the oil phase under st...

Embodiment 3

[0052] The preparation method embodiment 3 of the color-changing adsorption material for cigarette filters of the present invention adopts the following steps:

[0053] 1) Fully swell polyvinyl alcohol 1788 in water, and then heat it to fully dissolve to obtain a polyvinyl alcohol solution, add sodium chloride to the polyvinyl alcohol solution to dissolve, and obtain a water phase; in the water phase, polyvinyl alcohol The mass fraction is 1.5%, and the mass fraction of sodium chloride is 10%;

[0054] Mix divinylbenzene, methyl methacrylate, and 120# gasoline in a mass ratio of 40:60:100, then add initiator azobisisobutyronitrile (azobisisobutyronitrile accounts for methyl methacrylate and 1.5% of the total mass of divinylbenzene) mixed uniformly to obtain an oil phase;

[0055] Add the water phase into a 250ml three-neck flask equipped with a stirrer, reflux condenser and thermometer, raise the temperature to 40°C, add the oil phase under stirring, the mass ratio of the oil...

Abstract

The invention relates to a discoloration adsorption material for a cigarette filter tip and a preparation method thereof, and the cigarette filter tip. The preparation of the discoloration adsorbent material for the cigarette filter tip includes the steps: 1) carrying out amination reaction of polyacrylate porous resin to produce aminated polyacrylate porous resin; and 2) uniformly mixing the obtained aminated polyacrylate porous resin of the step 1) and natural pigments in a solvent, and thus obtaining the product. After flue gas flows through the material, the loaded natural pigments have acertain adsorption effect on heavy metal elements and have obvious discoloration effect; the aminated polyacrylate porous resin has porous and surface amination characteristics, can play a role in selectively enhancing the adsorption effect of harmful components such as hydrogen cyanide and volatile carbonyl compounds in flue gas; the discoloration adsorption material has strong adsorption effectson various harmful components in the flue gas, and can make the filtration and harmful reduction effects of the cigarette filter tip more prominent.

Description

technical field [0001] The invention belongs to the field of functional materials for cigarette filters, and in particular relates to a color-changing adsorption material for cigarette filters, a preparation method thereof, and a cigarette filter. Background technique [0002] As an indispensable part of cigarette products, tobacco materials (cigarette paper, tipping paper, forming paper, filter rods, additives, and packaging materials, etc.) are not only the key factors that determine the quality of cigarette products, but also promote the reform and innovation of cigarette products , The core element of rapid development.
