Problems solved by technology

[0005] However, the time for the smoke to pass through the filter is very short, and at the same time, the various components in the smoke are mixed together and pass through the filter in the form of aerosol. In addition to improving the taste or irritation, the existing additives cannot effectively remove harmful substances in the smoke , and the preparation process is complicated, so we consider using polymers including polyvinylpyrrolidone in additives

Abstract

The invention relates to an additive to reduce release of cigarette crotonaldehyde and a preparation method and application thereof. The additive comprises, by weight, 1-10 parts of a polymer, 0.5-1.5parts of a polymer, 0.5-1.5 parts of iodine particles, 0.5-10 parts of activated carbon, 10-100 parts of an alcohol solvent, and 10-100 parts of a complex solvent; the polymer is one or more of polyvinylpyrrolidone and N-vinylpyrrolidone-maleic acid copolymers having a molecular weight of 1000-1000000. Liquid adsorption modification is performed on the surface of activated carbon, so that material-smoke contact area is enlarged, and adsorption efficiency and capacity are increased for crotonaldehyde in smoke; after the additive is added to a filter tip, the content of crotonaldehyde in smokecan be significantly reduced, no significant influence is caused upon taste of cigarettes, and stimulation is improved.

Description

technical field [0001] The invention relates to an additive, especially an additive for reducing the release of crotonaldehyde from cigarettes, and also relates to a preparation method and application thereof, belonging to the field of tobacco. Background technique [0002] Cigarette smoke is a complex chemical system that is constantly changing. At present, there are more than 4,000 chemical substances in cigarette smoke that have been confirmed by research, of which more than 150 are potentially harmful to the human body. Crotonaldehyde is one of the main volatile carbonyl compounds in mainstream cigarette smoke. The substance is colorless and flammable, and has a strong irritating and tear-inducing effect on human eyes. Crotonaldehyde in smoke is inhaled into the body through the respiratory tract and digestive tract, causing certain harm to the human body, and has been listed as one of the main harmful substances in mainstream cigarette smoke. [0003] The production o...
