Problems solved by technology

The existing additive technology mainly adds additives to shredded tobacco and filter sticks, but when added to shredded tobacco, the additives will participate in the combustion at the same time as the cigarette is sucked, which will not only lose the proper effect of reducing harm and increasing flavor, but also may cause Decomposition produces new harmful substances

Embodiment 1

[0026] Add 1 g of acrylic acid, 0.05 g of sodium persulfate, 0.001 g of N,N'-methylenebisacrylamide, and 0.005 g of graphene oxide to 10 g of water, stir well, ultrasonically treat it at 20°C for 20 min, add a circular In the mold, pass nitrogen protection, heat to 50 ° C, react for 6 hours, take out, add water to wash and swell balance for 48 hours, and then freeze-dry at -50 ° C for 1 hour; after taking out, spray with the tobacco flavor material to obtain graphite. Ethene-polymer composite aerogel filter fragrance stick. The obtained round flavor stick is added to the filter tip to prepare a cigarette, the tar content of the smoke is reduced, the cool feeling is enhanced, and the comfort and the elegant feeling of the smoke are enhanced.

Embodiment 2

[0028] Add 1 g of acrylamide, 0.005 g of ammonium persulfate, 0.01 g of N,N'-methylenebisacrylamide, and 0.005 g of graphene oxide into 50 g of water, stir evenly, ultrasonically treat it at 20°C for 20 minutes, and add it to a triangular mold In the medium, nitrogen protection, heated to 70 ℃, the reaction time is 0.5 hours, take out, add methanol cleaning agent to clean and swell for 12 hours, and then freeze-dry at -10 ℃ for 6 hours; That is, the graphene-polymer composite aerogel filter fragrance stick is obtained. The obtained triangular spice stick is added to the filter tip to prepare a cigarette, the tar content of the smoke is reduced, the aroma volume is increased, and the comfort and elegant feeling of the smoke are enhanced.

Embodiment 3

[0030] Add 0.5 g of acrylamide, 0.5 g of acrylic acid, 0.025 g of potassium persulfate, 0.015 g of N,N'-methylenebisacrylamide, and 0.015 g of graphene oxide to 20 g of water, stir well, and ultrasonically treat at 20°C 20min, put it into the pentagonal mold, pass nitrogen protection, heat to 60 °C, the reaction time is 5 hours, take it out, add acetone cleaning agent to clean and swell for 30 hours, and then supercritically dry with carbon dioxide, the supercritical condition is 30 °C, 7 MPa , dried for 48 hours, taken out and sprayed with fragrance substances extracted from plants such as flowers and plants to obtain a graphene-polymer composite aerogel filter tip fragrance stick. The obtained pentagonal flavor stick is added to the filter tip to prepare a cigarette, the tar amount of the smoke is reduced, the aroma amount is increased, the cool feeling is enhanced, and the smoke comfort and elegant feeling are enhanced.

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 aerogel filter tip fragrance 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 limits on the amount of tar in cigarette smoke, and the tobacco industry in various countries has also invested a lot of effort in the research of technology to reduce cigarette tar, and has made great progress. In recent years, with the extensive publicity of smoking and health issues in China, people's quality concept of cigarette production and consumption has also undergone a huge change, and smokers' safety awareness of smoking has been 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 its harmful components in ...
