Abstract

The invention provides a cigarette holder filtering material and a preparation method thereof. The preparation method includes the following steps: taking peanut shells to perform crushing, adding deionized water to perform soaking, and performing filtering and drying so that peanut shell powder can be obtained; adding the peanut shell powder into a nitric acid solution, performing water-bath heating and stirring, performing filtering, washing filter residue with the deionized water until the pH is in neutrality, and performing drying to obtain activated peanut shell powder; adding a sodium chloride and sodium silicate aqueous solution into the activated peanut shell powder, performing stirring, and slowly dropping hydrochloric acid to adjust the pH to acidity; performing heating after reaction, performing aging, performing centrifugal separation, washing the filter residue with the deionized water and ethanol, and drying the filter residue to obtain a powdery product; and adding the powdery product into a lysine solution, performing stirring reaction, and performing filtering to obtain the cigarette holder filtering material. The provided cigarette holder filtering material has good adsorption effect on lead, cadmium, mercury, tar, nicotine, HCN, benzo(a)pyrene, etc., so that the cigarette holder filtering material has excellent capability of reducing harmful substances; and cigarette styles are not changed, so that the feeling and quality of cigarettes has no substantial differences.

Description

technical field [0001] The invention relates to a cigarette tip filter material and a preparation method thereof, belonging to the technical field of cigarette materials. Background technique [0002] Cigarette combustion will produce more than 6,000 chemical substances, of which there are more than 600 harmful substances in the smoke produced by combustion, including carbon monoxide, nicotine, nitrosamines, tar, phenol, hydrogen cyanide, crotonaldehyde, benzopyrene , benzoanthracene, heavy metal elements lead, cadmium, arsenic, etc. These substances enter the human body along with the smoke and deposit in the lungs and other organs of the human body, leading to chronic poisoning of human organs, tissue lesions, and various serious diseases such as lung cancer. [0003] Cigarette filters are one of the effective means to reduce the harm of cigarettes. Cut tobacco and cigarette paper are burned to produce smoke, which is filtered through cigarette filters to form smoke smoked...
