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 components in the smoke are mixed together and pass through the filter in the form of aerosols.
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, which cannot quickly and selectively reduce the content of crotonaldehyde in the smoke

Abstract

The invention relates to a compound additive for reducing the amount of crotonaldehyde released in flue gas, a preparation method and application thereof. The compound additive comprises the following raw materials in parts by weight: 1-20 parts of a polymer, 0.1-5 parts of a phosphoric acid compound, a polyol 0.1-5 parts and 20-50 parts of solvent; Described polymer is one or more of polyvinylpyrrolidone and vinylpyrrolidone-maleic acid copolymer with molecular weight of 1000-1000000. The present invention can rapidly and selectively reduce the content of crotonaldehyde in smoke by selecting suitable ligands for PVP, and has remarkable effect.

Description

technical field [0001] The invention relates to a compound additive, in particular to a compound additive for reducing the release of crotonaldehyde in smoke, and also relates to a preparation method and application thereof, belonging to the field of cigarettes. Background technique [0002] Cigarette smoke is produced by the combustion, distillation and cracking of tobacco and its auxiliary materials during the smoking process of cigarettes. It is a rather complex mixture. After the publication of the first list of harmful substances in cigarette smoke, the relationship between smoking and health The relationship is gradually being paid attention to by the public. At present, tar reduction and harm reduction have become the main subject of cigarette industry technology research. Although tar reduction can improve the safety of cigarette smoke to a certain extent, tar reduction is to reduce the particle phase components non-selectively. When the tar content of cigarettes is...
