Embodiment 1
[0029] The tobacco materials suitable for smoking provided in this embodiment are calculated in parts by mass, and the specific dosage of each material is: 20 parts of tobacco stem powder, 30 parts of tobacco water extract, 30 parts of glycerin, and 2 parts of aluminum oxide powder , 2.5 parts of polyethylene glycol (molecular weight 2000), 3 parts of sodium carboxymethyl cellulose;
[0030] The tobacco stem powder is the tobacco stem in the cigarette production process, and the particle size is 40 mesh;
[0031] The alumina powder has a particle size of 100 mesh;
[0032] The tobacco water extract can be prepared by using specific similar commercially available products, or it can be prepared by referring to the following method: take the waste tobacco powder in the cigarette production process, add water after drying according to the ratio of material to liquid 1:3 (w / w) , After extraction at 90°C for 2 hours, the solid-liquid separation was performed, and the filtrate was ...
Embodiment 2
[0041] The tobacco material suitable for smoking provided by the present embodiment, in parts by mass, the specific consumption of each material is: 30 parts of tobacco powder, 40 parts of tobacco 70% ethanol extract, 20 parts of propylene glycol, 0.2 part of graphene powder , polyethylene glycol (molecular weight 3000) 2 parts, hydroxypropyl cellulose sodium 5 parts;

Abstract
The invention belongs to the technical field of tobacco, and in particular relates to a tobacco material for smoking and a preparation method thereof. The tobacco material is sheet-like or film-like, with a thickness of 0.1-2mm; it is made of tobacco powder, tobacco extract, aerosol generating agent, heat-conducting material, polyethylene glycol and adhesive; in parts by mass, each The specific dosage of materials is: 10~50 parts of tobacco powder, 20~50 parts of tobacco extract, 10~30 parts of aerosol generating agent, 0.1~5 parts of thermal conductive material, 1~5 parts of polyethylene glycol, 1 part of adhesive ~5 servings. The advantages of the present invention mainly include: the heating condition of the tobacco material is improved by loading the heat-conducting material in the tobacco material, and the smoke concentration is better improved; the heating uniformity of the tobacco material is improved by uniformly dispersing the heat-conducting material in the polyethylene glycol solution, The uniformity of smoke release is significantly improved; the range of tobacco materials is widely used.
Description
technical field [0001] The invention belongs to the technical field of tobacco, and in particular relates to a tobacco material for smoking and a preparation method thereof. Background technique [0002] As the intensity of tobacco control continues to increase globally, the international tobacco field has been committed to seeking the direction of future tobacco product development. Heat-not-burn tobacco products are a new type of tobacco products, which produce smoke for consumers to smoke in a non-combustible state. Compared with traditional cigarettes, the smoking temperature is significantly lower, and sidestream smoke and some harmful components are obvious. It has obvious advantages in reducing environmental pollution and health risks. However, since the smoking temperature of heat-not-burn tobacco products is significantly lower than that of traditional cigarettes, the degree of pyrolysis reaction of tobacco materials is relatively limited, and the performance of mo...
