[0051] The present invention also provides a method for preparing a heat-not-burn cigarette wick material, wherein the heat-not-burn cigarette wick material is the above-mentioned heat-not-burn cigarette wick material, and the preparation method includes:
[0052] The tobacco raw material is pulverized and sieved to obtain tobacco powder;
[0053] The plant fiber is formed into a plurality of single fibers through non-hydrolyzed fibers, and then a substrate is formed through an air former;
[0054] Mixing the cigarette powder, the smoking agent, the auxiliary material and water to obtain a coating liquid;
[0055] The coating liquid is sprayed and dried on the substrate.
[0056] Preferably, the particle size of the smoke powder is 40-400 mesh, such as 40 mesh, 80 mesh, 100 mesh, 150 mesh, 200 mesh, 250 mesh, 300 mesh, 350 mesh or 400 mesh, etc.
[0057] Preferably, the length of the single fiber is 0.5-3.0 mm, such as 0.5 mm, 1.0 mm, 1.5 mm, 2.0 mm, 2.5 mm or 3.0 mm, and th...

[0062] Example 1
[0063] A heat-not-burn cigarette core material comprises the following raw materials in parts by weight: 10 parts of unbleached wood pulp fibers, 49 parts of flue-cured tobacco leaf monomer (Yunyan 85), 40 parts of glycerin and 1 part of ethyl cellulose.
[0064] The preparation method of the heat-not-burn cigarette wick material comprises the following steps:
[0065] (1) Preparation of tobacco powder: take the flue-cured tobacco leaf monomer with a moisture content of less than 10%, pass through a 40-mesh sieve after being pulverized by a pulverizer, and set aside for later use;
[0066] (2) preparation of coating liquid: evenly mix the prepared cigarette powder with glycerin, guar gum and an appropriate amount of water to form a coating liquid with a solid content of 25%, for subsequent use;
[0067] (3) Preparation of base sheet: after defibrating the unbleached wood pulp fibers into several single fibers with a length of 0.5 mm, the base sheet is forme...

[0069] Example 2
[0070] A heat-not-burn cigarette wick material, comprising the following raw materials in parts by weight: 20 parts of unbleached wood pulp fibers, 70 parts of flue-cured tobacco leaf group (K326, Yunyan 85, Hongda), 5 parts of glycerin and guar gum 5 servings.
[0071] The preparation method of the heat-not-burn cigarette wick material comprises the following steps:
[0072] (1) Preparation of tobacco powder: take the flue-cured tobacco leaf group with moisture control below 10%, pass through a 250-mesh sieve after being pulverized by a pulverizer, and set aside for later use;
[0073] (2) preparation of coating liquid: evenly mix the prepared cigarette powder with glycerin, guar gum and an appropriate amount of water to form a coating liquid with a solid content of 5%, for subsequent use;
[0074] (3) Preparation of base sheet: after defibrating the unbleached wood pulp fiber into several single fibers with a length of 1.0 mm, the base sheet is formed by...
