Smoking material for low-temperature nonflammable cigarette and preparing method thereof

The invention relates to a smoking material for a low-temperature nonflammable cigarette and a preparing method of the smoking material for the low-temperature nonflammable cigarette. The preparing method of the smoking material comprises the steps that tobacco raw materials are smashed into powder, after particles are made from the powder through microwave expansion, the particles are sufficiently and evenly mixed with fragrant plant particles, a tobacco flavor, a starch tackiness agent, propylene glycol and a tobacco starch humectant, then a semi-finished smoking material is obtained, and the smoking material is obtained finally by conducting pressing forming through a die. According to the smoking material for the low-temperature nonflammable cigarette and the preparing method of the smoking material for the low-temperature nonflammable cigarette, by conducting microwave expansion on the tobacco raw materials and designing a formula reasonably, the content of the wood flavor in the tobacco raw materials can be greatly reduced, and sensual comfort of smoking can be improved remarkably; meanwhile, the square tobacco expansion particles and the round tobacco expansion particles which are mixed in two shape proportions serve as the main materials, the hollow special-shaped bar-shaped or sheet materials with multiple ducts are arranged, in this way, the heating area and the heating uniformity of the smoking material can be improved greatly, and smoke can be formed rapidly at a relatively low heating temperature. During formula design, the environment-friendly materials such as the starch humectant and starch glue are used, and therefore smoking safety is improved.
