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 gram of acrylic acid, 0.05 gram of sodium persulfate, 0.001 gram of N,N'-methylenebisacrylamide, 0.005 gram of graphene oxide into 10 gram of water, stir evenly, sonicate at 20°C for 20 minutes, and add In a shaped mold, protected by nitrogen, heated to 50°C, reacted for 6 hours, taken out, added water to wash and swell for 48 hours, and then freeze-dried at -50°C for 1 hour; after taking it out, spray it with tobacco aroma substances to obtain graphite Olefin-polymer composite airgel filter flavor sticks. Adding the obtained round spice stick into the filter tip to prepare a cigarette, the tar amount in the smoke is reduced, the refreshing feeling is enhanced, and the comfort and the elegant feeling of the smoke are enhanced.

Embodiment 2

[0028] Add 1 gram of acrylamide, 0.005 gram of ammonium persulfate, 0.01 gram of N,N'-methylene bisacrylamide, 0.005 gram of graphene oxide into 50 grams of water, stir evenly, ultrasonically treat for 20 minutes at 20°C, and add to a triangular mold , under nitrogen protection, heated to 70°C, the reaction time is 0.5 hours, taken out, added methanol cleaning agent to wash the swelling balance for 12 hours, and then freeze-dried at -10°C for 6 hours; after taking out, impregnated with tobacco extract isolate, That is, the graphene-polymer composite airgel filter fragrance stick is obtained. Adding the obtained triangular spice sticks into the filter tip to prepare cigarettes, the amount of tar in the smoke is reduced, the amount of aroma is increased, and the comfort and elegance 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 into 20 g of water, stir evenly, and ultrasonically treat at 20°C After 20 minutes, put it into a pentagonal mold, protect it with nitrogen, heat it 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 dry it supercritically 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 airgel filter fragrance stick. Adding the obtained pentagonal spice stick into a filter tip to prepare a cigarette, the smoke tar amount is reduced, the aroma amount is increased, the refreshing 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 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...
