Abstract

The invention discloses a cigarette filter rod capable of reducing the content of volatile carbonyl compounds in cigarette smoke and a preparation method of the cigarette filter rod. The cigarette filter rod is characterized in that mesoporous alumina particles capable of obviously reducing the content of the volatile carbonyl compounds in the cigarette smoke are added in a common cellulore filter rod to form the binary or ternary compound cellulore filter rod. The grain size of mesoporous alumina is 20-60 meshes, the average pore size of the mesoporous alumina is 10nm to 30nm, the BET surface area of the mesoporous alumina is 100-300 m<2> / g, and the crystal form of the mesoporous alumina is gamma-type alumina. The additive amount of the mesoporous alumina in the binary compound filter rod of each piece of cigarette is 10-40 mg / piece, and the additive amount of the mesoporous alumina in the ternary compound filter rod of each piece of cigarette is 70-120 mg / piece. Because of a specific acid environment of the smoke and molecular structure features of the carbonyl compounds, the mesoporous alumina can perform preferential adsorption on the volatile carbonyl compounds in the cigarette smoke by virtue of an electrostatic adsorption function and a nano-pore confinement effect, thereby achieving the purpose of alleviating the harm of the cigarette.

Description

technical field [0001] The invention relates to the field of manufacturing and processing of cigarette materials, in particular to a cigarette filter rod capable of reducing the content of volatile carbonyl compounds in cigarette smoke and a preparation method thereof. Background technique [0002] The health damage of smoking has become a global concern. Smoke contains a variety of harmful components, and volatile carbonyl compounds are one of the most important types, and they are listed among the 44 harmful substances in smoke listed in the Hofman list. Volatile carbonyl compounds in flue gas mainly include eight compounds including formaldehyde, acetaldehyde, acetone, acrolein, propionaldehyde, crotonaldehyde, 2-butanone and butyraldehyde, which have strong cilia toxicity and long-term exposure will cause Chronic rhinitis, nervous system dysfunction, etc. Among them, formaldehyde, acrolein and crotonaldehyde have carcinogenic effects on animals and humans. Volatile ca...
