Embodiment 1

[0029] 500g particle diameter is the nano-silica of 20nm, and 500g particle diameter is the nanometer ferric oxide of 10nm to be added in the concentrated solution (concentration is 40%) of the paper-making method tobacco sheet of 100Kg, under the rotating speed of 2000rmp at stirring speed , after being fully dispersed and uniform, it is prepared as a coating solution.

[0030] Apply the above-mentioned coating solution containing compound additives evenly to the base sheet of 100Kg paper-making tobacco sheet by means of coating, after drying, slice into paper-making tobacco sheet, finally cut into shreds, roll into cigarettes, and measure the cigarette smoke The content of phenol and 3,4-benzo[a]pyrene in the air, the research results show that the additive can reduce the content of phenol and 3,4-benzo[a]pyrene in the smoke of paper-making tobacco sheet cigarettes respectively : The phenol content decreased by 66.7%, and the total amount decreased from 4.1μg / Cigarette to 1....

Embodiment 2

[0032] 500g particle diameter is the zeolite powder of 20nm, and 500g particle diameter is the nanometer iron sesquioxide of 10nm to be added in the concentrate (concentration is 40%) of the papermaking method tobacco sheet of 100Kg, under the rotating speed of 2000rmp at stirring speed, After fully and uniformly dispersed, a coating liquid is prepared.

[0033] Apply the above-mentioned coating solution containing compound additives evenly to the base sheet of 100Kg paper-making tobacco sheet by means of coating, after drying, slice into paper-making tobacco sheet, finally cut into shreds, roll into cigarettes, and measure the cigarette smoke The content of phenol and 3,4-benzo[a]pyrene in the air. The research results show that the additive can reduce the content of phenol and 3,4-benzo[a]pyrene in the smoke of paper-making tobacco sheet cigarettes respectively: The content of phenol was reduced by 55%, and the total amount was reduced from 4.1μg / Cigarette to 1.84μg / Cigarette,...

Abstract

The invention relates to a method for preparing a tobacco sheet capable of reducing harmful substances in smoke, which comprises the following steps of: (1) after extracting tobacco powder and tobacco stalks, which are used as the raw materials, by hot water or 75 to 95 mass percent of ethanol, concentrating into tobacco concentrated solution with the solid content of 20 to 55 percent; (2) adding 0.05 to 5 mass percent of metallic oxide, metal salt and a mixture in any ratio into the tobacco concentrated solution; (3) adding 0.05 to 8 percent of inorganic mineral adsorbing material into the tobacco concentrated solution to obtain a composite additive; and (4) coating the tobacco concentrated solution added with the composite additive on a substrate of the tobacco sheet. When the tobacco sheet prepared by the method is burnt, on one hand, the pyrolysis process in the burning process can be catalyzed and the generation of benzene ring substances and the like can be reduced, and on the other hand, generated particle substances with high molecular mass, particularly substances containing benzene rings, are adsorbed into a pore structure of the additive, so that the aim of avoiding the harmful substances being sucked into the mouth is fulfilled.

Description

technical field [0001] The invention belongs to the technical field of tobacco sheet production by papermaking, in particular to a method for preparing tobacco sheet capable of reducing harmful substances in smoke. Background technique [0002] Modern scientific research shows that the direct harm caused by cigarette smoke to the human body is: the gas phase mainly contains carbon monoxide, nitrogen oxides, volatile aromatic hydrocarbons, hydrogen cyanide, volatile aldehydes and ketone compounds, etc.; Aromatic hydrocarbons, N-nitrosamines, phenolic substances, free radicals, certain heterocyclic compounds, heavy metals and radioactive substances, etc. How to selectively reduce the harmful substances in cigarette smoke has been a difficult problem that has plagued the tobacco industry for a long time. At present, the reduction of harmful components in cigarette smoke is generally achieved by reducing the amount of tar released from cigarettes. For this reason, whether it i...
