Problems solved by technology

However, there are certain technical problems in using natural amino acids directly for paper coating
When the amino acid aqueous solution is directly used for paper coating, there will be problems such as easy paper breakage, difficult operation, small coating amount, and low effective content of functional materials; Flying powder and defoaming will occur during the process of troughing the filter rods, which will seriously affect the production
However, in the prior art, there is no better way to load natural amino materials on coated paper

Abstract

The invention belongs to the technical field of cigarette harm reduction, and in particular relates to a functional coating material liquid, a preparation method of the coating material liquid and its application in cigarettes. The coating liquid is prepared by swelling and dissolving polyvinyl alcohol, adding amino material and diluent, heating and stirring. The advantage of the present invention is that the coating material liquid can reach a higher loading capacity on the raw material paper, even if the loading capacity is high, the amino material is not easy to cause powder flying and defoaming on the raw material paper. The invention can reduce the release of crotonaldehyde in mainstream smoke by more than 20%, and reduce the release of HCN by more than 50%. Meanwhile, the sensory evaluation results show that the sensory quality of cigarette smoking is not significantly affected. This result shows that the functional coating liquid provided by the present invention reduces the harmful substances in the mainstream smoke of cigarettes, and at the same time, does not significantly affect the smoking sensory quality of cigarettes, so it has good significance for popularization and application.

Description

technical field [0001] The invention belongs to the technical field of cigarette harm reduction, and in particular relates to a functional coating liquid, coated paper and their application in cigarettes. Background technique [0002] Coated paper has an important application in the production of cigarette filter rods. Tobacco science and technology workers prepare composite filter rods and special filter rods by loading functional materials on coated paper, which can be used to reduce the release of harmful components in mainstream cigarette smoke. At present, researchers have developed functional paper coated with metal complex materials and alkaline polymer materials, which are used in the production of cigarette filter rods and have achieved good results. However, in recent years, with the increasingly stringent requirements of food safety and hygiene standards, the safety requirements of smoking materials are also getting higher and higher, which greatly limits the app...
