[0003] In the prior art, although the addition of adsorbent materials to cigarette filter materials is an important means to reduce the hazards of smoking, the addition of adsorbent materials in the prior art is often the addition of a single material, and it is difficult to selectively reduce harmful components without reducing the aroma. purpose of ingredients

Embodiment Construction
[0021] A method for preparing cigarette filter paper with selective adsorption function, comprising the following steps:
[0022] (1) Acidification treatment of sepiolite:
[0023] 40 parts by weight of sepiolite are superfinely crushed, added to 320 parts of distilled water, stirred at room temperature for 6 hours to hydrate, left to stand for 40 minutes, filtered and dried, added to a certain concentration of strong acid solution, mixed evenly, in Hot acid treatment was carried out at 75°C for 12 hours, and after standing for precipitation, it was washed several times with deionized water, filtered by suction and dried in an oven to obtain acidified modified sepiolite;
[0024] (2) Preparation of cationic modified starch:
[0025] Add 8 parts of starch, 8 parts of acrylic acid and 2 parts of 0.01mol / L cerium ammonium nitrate aqueous solution into the reaction tank, react at 80°C for 1.5 hours, let it stand and cool to 45°C, add 0.8 parts of ammonium persulfate, and fill wit...

The invention discloses a preparation method of paper of a cigarette filter with a preferential adsorption function. In the preparation method, sepiolite modified by acidification is used, so that a part of channels in a sepiolite crystal are communicated with one another, the inner aperture and the porosity are increased, the specific surface area of the sepiolite crystal is increased, and the adsorption property of the sepiolite is improved; due to the addition of the sepiolite, the filter has preferential adsorption capacity and can preferentially adsorb polar compounds that are harmful tohealth in smoke, such as nitriles, acetone, acrolein and the like, and the filter can slightly adsorb non-polar compounds, such as aromatic compounds including methyl furan, dimethyl furan and the like, so that cigarettes are richer in fragrance.
Description
technical field [0001] The invention relates to the technical field of cigarette filter material processing, in particular to a method for preparing cigarette filter paper with selective adsorption function. Background technique [0002] As people pay more and more attention to smoking and health issues, low-tar and low-harm cigarettes are becoming more and more popular and promoted. Harmful components in mainstream cigarette smoke account for less than 1% of tar, most of which are aroma components, which can bring pleasure and physiological satisfaction to consumers, so to some extent, harm reduction The significance is greater than that of reducing focus. Therefore, for Chinese-style cigarettes, the State Tobacco Monopoly Administration proposed that "the harmful components in tar are only a very small part of it. When the tar reduction reaches a certain level, it is the research in this field to take measures to selectively reduce the harmful components of cigarettes." ...
