Energetic material for cigarette and low-temperature heating cigarette

Abstract

The invention discloses an energetic material for a cigarette and a low-temperature heated cigarette, wherein the energetic material for the cigarette is processed by mixing the following raw materials in percentage by mass: 40-55% of an oxidizing agent, 25-35% of combustible agent, 5-20% of a binding agent and 3.5-20% of other adjuvant materials; a pentagram-shaped copper barrel (13) is arranged in a heat source area (1) of the low-temperature heated cigarette; five points of the pentagram-shaped copper barrel (13) are connected to the wall of an insulating ceramic sleeve (5); and the energetic material (10) fills the pentagram-shaped copper barrel (13). The energetic material disclosed by the invention is relatively easily combustible, and the combustion speed and temperature are controllable; heat energy released from the combustion is effectively transmitted to air in the modes of transfer and radiation only; and formed hot air flows to an aerosol generating agent and tobacco shreds and is capable of heating the aerosol generating agent and the tobacco shreds, so that smoke is generated.

Description

technical field [0001] The invention relates to an energetic material for cigarettes and a low-temperature heating cigarette, belonging to the field of new tobacco products. Background technique [0002] Low-temperature heating cigarettes generally convey satisfaction and tobacco aroma to consumers by heating non-burning tobacco. Their appearance and consumption methods are also similar to traditional cigarettes, which to a certain extent adapt to and satisfy consumers' physiological needs and psychological needs. This "heat not burn" method enables the tobacco to be heated only at a lower temperature (ideal temperature range 300-500°C), avoiding the generation of a large number of harmful compounds caused by the high temperature environment when the tobacco is burned, and because there is basically no side effects No second-hand smoke will be generated, no impact on the public environment, and the contradiction between smoking and smoking bans in public places will be alle...

Problems solved by technology

Although carbonaceous heat source materials have become one of the main heat sources for low-temperature cigarettes due to their advantages of safety, stability, speed and efficiency, and low price, at present, they still suffer from excessive CO release, difficulty in igniting, easy shedding, and easy ignition of shredded tobacco. And other issues

Although some problems can be solved by formula composition change, physical structure design and processing technology adjustment, it will also bring new problems. For example, the addition of micro-nano materials in patents 101098635B, CN1039711A, and CN1100453A reduces the amount of CO released, but it brings Reliance on the safety of low-temperature cigarettes; Patents CN102458165A, US4881556, CN101420876A, CN89104936.3, CN1100453A and CN103263084A etc. increase the surface area of ​​carbonaceous heat source materials by setting multiple longitudinal passages, and improve combustion sufficiency and ignitability , but it brings difficulties and challenges to the processing; patents such as CN102458165A, US4714082 and CN1886069A use glass fiber and other heat insulating materials to wrap the carbon heat source, avoiding the problem of easy falling off, but the glass fiber will inevitably fall off and be absorbed during packaging and transportation. To the side of the filter, the smoker may inhale the glass fiber into the body, which is harmful to health

In addition, although the carbonaceous heat source is not in direct contact with the tobacco, the high-temperature airflow (greater than 800°C) generated by the combustion of the carbonaceous heat source may ignite the shredded tobacco, and once the shredded tobacco is burned, it will release a large amount of harmful components

Therefore, it is hoped to find a new type of heat source material to replace the carbonaceous heat source material, so as to fundamentally solve the problems of high CO production, difficult ignition, and easy fall off of the heat source.
