Cigarette tar filter material and preparation method thereof

Abstract

The invention relates to a cigarette tar filter material and a preparation method thereof and belongs to the technical field of tar filter materials. The cigarette tar filter material comprises 10-15parts of methyl styrene, 20-30 parts of n-butyl methacrylate, 3-5 parts of acrylonitrile, 15-20 parts of stearyl methylacrylate, 15-20 parts of p-diphenylsulfone methylacrylate, 3-5 parts of divinylbenzene, 0.5-1 part of neopentyl glycol dimethacrylate, 30-50 parts of diethylbenzene, 20-30 parts of No. 120 gasoline, 1-3 parts of dibenzoyl peroxide, 5-10 parts of polyvinyl alcohol, 1-3 parts of gelatin, 3-5 parts of methylene blue, 15-20 parts of sodium carbonate, and 500-800 parts of deionized water. A cigarette filter tip made with tar-absorbing resin produced herein is capable of effectivelyremoving harmful substances in cigarette, with inherent aroma of cigarette retained to maximum extent.

Description

technical field [0001] The invention relates to a filter material and a preparation method thereof. More specifically, the invention relates to a cigarette tar filter material and a preparation method thereof, belonging to the technical field of tar filter materials. Background technique [0002] Cigarettes produce not only nicotine but also tar when they are burned. Studies have shown that tar contains about 0.6% of carcinogens. Such as 2-naphthylamine, 4-aminobiphenyl, 3,4-benzopyrene and other condensed aromatic hydrocarbons, phenols, aromatic amines and nitrosamines, etc., which seriously endanger human health. How to effectively reduce the amount of tar is not only one of the hotspots of tobacco science and technology workers, but also a concern of consumers. The filter tip can effectively intercept the harmful components produced when smoking tobacco, and has become an indispensable part of low-tar cigarettes. However, the addition of adsorbents in the filter has an...

Although these adsorbents can reduce the amount of tar and nicotine or selectively adsorb some components, they have no obvious effect on increasing the ratio of nicotine and tar to the ratio of nicotine and tar and reducing polycyclic aromatic hydrocarbons while reducing the amount of tar and nicotine, and they cannot be well To preserve the inherent flavor of cigarettes
