Abstract

The invention relates to a pH responsive cigarette filter tip functional material and a preparation method thereof, and a cigarette filter tip. The preparation of the functional material includes thesteps: 1) carrying out amination reaction of polyacrylate porous resin to produce aminated polyacrylate porous resin; and 2) uniformly mixing the aminated polyacrylate porous resin and a pH indicationdiscoloration agent in water, and thus obtaining the product. The pH indication discoloration agent is any one of bromocresol green, bromocresol green sodium salt, bromothymol blue, Congo red, methylred or bromcresol purple. The cigarette filter tip functional material obtained by the method has obvious discoloration effect; at the same time, through cooperation of the porous structure of the material itself and the amino functional groups, the selective adsorption effect of volatile carbonyl compounds and hydrogen cyanide in flue gas is strengthened, the release amount of harmful componentsin the flue gas can be effectively reduced, and the harm reduction effect of cigarettes is more prominent.

Description

technical field [0001] The invention belongs to the field of cigarette filter functional materials, and in particular relates to a pH-responsive cigarette filter functional material, 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. The major breakthroughs and leaps in the development of the tobacco industry and tobacco products are inseparable from the innovation and application of tobacco materials. [0003] The application of filter materials has brought about the advent of filter cigarettes, which has effectively promoted the epoch-making leap of cigarette products; the application of vent...
