Abstract

The invention relates to a graphene-polymer composite aerogel filter perfume rod and a preparation method there, which belongs to the technical field of cigarette. The method comprises the following steps: graphene, an initiator, acrylic acid or acrylamide or a mixture, and a cross-linking agent are added in an aqueous solution and reacted to obtain a gel stick, after desolventizing, the required perfume rod s obtained by dipping essence perfume. The graphene-polymer composite aerogel is in a porous network structure, and has high specific surface area and is in favor of adsorption of essence perfume. Due to excellent physical and chemical performance of the graphene material, the graphene-polymer composite aerogel has good interception effect to flue gas. The cost of used raw material is low, operation is simple, appearance is novel, different fragrance and flavour of cigarette can be endowed by loading different essence perfume, and the filter perfume rod has good market application prospect.

Description

technical field

[0001] The invention relates to a graphene-polymer composite airgel filter spice stick and a preparation method thereof, belonging to the technical field of cigarettes. Background technique

[0002] At present, many countries in the world have made clear legal restrictions on the amount of tar in cigarette smoke, and the tobacco circles of various countries have also invested a lot of energy in the research of reducing cigarette tar technology, and have made great progress. In recent years, with the widespread publicity of smoking and health issues in China, people's perceptions of the quality of cigarette production and consumption have also undergone tremendous changes, and smokers' awareness of smoking safety has greatly improved. Reasonably reducing the tar content of cigarette products will meet the requirements of consumers and help improve the market adaptability and competitiveness of products. How to significantly reduce the tar and harmful componen...
