Problems solved by technology

[0003] Although the smoke of heat-not-burn cigarettes is relatively close to that of traditional cigarettes, there is still a big gap in sensory quality compared with traditional cigarettes
In particular, the smoke quality of heat-not-burn cigarettes is not strong enough, which affects the user's smoking experience and needs further improvement
In addition, during the smoking process of heat-not-burn cigarettes or other tobacco products, the smoke temperature is high, local overheating, and heating are uneven, which affects the user's smoking experience

Abstract

The invention provides a cigarette core material for heating incombustible cigarettes. The cigarette core material is prepared from the following components in percentage by weight: 10-50% of tobaccofiber and tobacco powder, 5-30% of wood pulp fibers, 5-30% of one or more of hemp fibers, bamboo fibers, soybean fibers, cocoon fibers, cotton fibers, polylactic acid fibers and modified cellulose fibers, 10-50% of tobacco essence, 10-30% of smoke producing agent, 1-10% of heat conduction material, 1-10% of phase change absorption material and 1-20% of paper coating component which is selected from one or more of a hydrophobic material, a microcapsule suspension and an essence suspension containing the tobacco powder. According to the cigarette core material, the heat conduction material is added, so that the heat can be uniformly conducted; the cigarette core paper is uniformly heated in the heating process; in addition, the phase change absorption material is used and is capable of achieving phase change and absorbing heat under the heated condition so as to prevent the cigarette core material paper from being locally overheated in the heating process.

Description

technical field [0001] The invention relates to the field of tobacco products, in particular to a smoke core material for heat-not-burn cigarettes and a preparation method thereof. Background technique [0002] Heat-not-burn cigarettes are a new type of tobacco product that has emerged rapidly in recent years. Its main feature is to use an external heat source to heat tobacco instead of burning tobacco, so that the aroma components and other substances in tobacco are released. Because tobacco products do not participate in combustion, a large amount of harmful components due to pyrolysis are avoided. While consumers are satisfied, the harm to the human body is reduced, and environmental pollution is reduced. According to the research results, the aerosol of heat-not-burn cigarettes is more than 90% less harmful than that of traditional cigarettes, and can provide a level of nicotine that is basically equivalent to that of cigarettes. [0003] Although the smoke of heat-not...
