Technical Field
The invention relates to the technical field of cigarettes, in particular to a material for heating a non-burning cigarette shell and a preparation method of the cigarette shell.
Background
Cigarettes are the most common tobacco consumer products at present, and when the cigarettes ignite cut tobacco, aerosol with nicotine, tobacco cracking substances, additional spices and the like is generated, wherein the nicotine is a component which mainly brings pleasure and addiction to smokers. When the common cigarette releases nicotine, the aerosol of the common cigarette contains various harmful substances generated during combustion and cracking, including carbon monoxide, crotonaldehyde, tobacco-specific nitrosamines (TSNAs), benzopyrene and the like, and has certain health hazard to human bodies.
Electronic cigarettes have been developed rapidly in recent years, but electronic cigarettes are electronic products simulating cigarettes by heating and atomizing liquid tobacco tar or semisolid tobacco paste with heating wires, and have the same appearance, smoke, taste and sensation as cigarettes. The electronic cigarette is a product which is powered by a rechargeable lithium polymer battery to drive an atomizer, nicotine and the like are changed into steam through heating tobacco tar in an oil tank, and then a user can suck the electronic cigarette.
Research shows that the content of harmful substances in smoke generated by heating and non-burning tobacco is 80% lower than that of the traditional cigarette, because the heating temperature of the tobacco is far lower than the burning temperature of the tobacco, the release of the harmful substances is limited to a great extent, and therefore, the treatment mode of heating and non-burning tobacco products reduces the harm to smokers due to smoking, and attracts attention of all parties.
