preparation example Construction

[0028] The preparation method of cigarette filter tip adsorption material provided by the invention comprises the following steps:

[0029] 1) subjecting the polymer porous adsorption resin to an amination reaction to obtain an aminated polymer porous adsorption resin;

[0030] 2) The aminated polymer porous adsorption resin is modified by complexing copper ions to obtain the final product.

[0031] The complex modification of copper ions includes mixing the aminated polymer porous adsorption resin with a solution containing copper ions.

[0032] The mixing is to add the aminated polymer porous adsorption resin into the solution containing copper ions and stir for 3-12 hours.

[0033] The copper ion complex modification further includes mixing the aminated polymer porous adsorption resin with the solution containing copper ions, separating the solid from the liquid, and drying the obtained solid at 40-60°C. The time of the drying treatment is 3-6 hours.

[0034] The copper ...

Embodiment 1

[0064] The preparation method of the cigarette filter adsorption material of the present embodiment comprises the following steps:

Abstract

The invention discloses an adsorption material of a cigarette filter, a preparation method of the adsorption material and the cigarette filter, and belongs to the technical field of cigarette filters.The preparation method comprises the steps that polymer porous adsorbent resin is subjected to an amination reaction to obtain amination polymer porous adsorbent resin; the amination polymer porous adsorbent resin is subjected to cupric ion complexing modification, and the adsorption material is prepared. The adsorption material of the cigarette filter can selectively reduce harmful components ofhydrogen cyanide, volatile carbonyl compounds and the like in main stream smoke, wherein the hydrogen cyanide is selectively reduced by 30-80%, and the total content of the volatile carbonyl compounds is selectively reduced by 20-50%; stimulation of the cigarette can be effectively reduced, and the sensory quality of the cigarette is improved; after a transparent composite filter stick is appliedto the cigarette, a consumer can directly observe the process that functional materials become yellow green from blue after harmful components in smoke are selectively adsorbed, and the novel performance of appearance of the cigarette and understanding of the consumer for the technological content of the cigarette are enhanced.

Description

technical field [0001] The invention relates to a cigarette filter adsorption material, a preparation method thereof and a cigarette filter, belonging to the technical field of cigarette filters. Background technique [0002] With the increasing attention to smoking and health issues, countries around the world are paying more and more attention to the development of cigarette filter materials and filter structures, and some functional materials have been added to filter rods to achieve the purpose of reducing tar and harm, such as The Chinese invention patent application with the application publication number CN101396170A discloses a composite cigarette filter made of modified adsorption material particles, which can remove some harmful components. The Chinese utility model patent with the authorized notification number CN201108028Y adds amine-based materials made of surfactants to cellulose acetate to obtain binary composite filters, which can selectively reduce harmful v...
