Cigarette filter tip adsorbing material and preparation method thereof

Abstract

The invention discloses a cigarette filter tip adsorbing material and a preparation method thereof. The adsorbing material has a porous structure and is processed by pickling shaddock skin inner layer, drying, crushing and granulating. The adsorbing material can effectively filter out tar, nitrosamine, benzopyrene and other hazardous substances generated during cigarette burning, thereby well protecting smoker health, has no off-flavor or off-odor when cigarette smoke gas passes, can also improve smoking mouthfeel and cigarette grade, has good processability and is favorable to manufacture of the cigarette filter tip adopting the material.

Description

technical field [0001] The invention belongs to the technical field of cigarette production, and in particular relates to a plant-type adsorption material used for cigarette filters and a preparation method thereof. Background technique [0002] The smoke released by tobacco burning contains more than 3,800 known chemical substances, most of which are harmful to the human body, including carbon monoxide, nicotine and other alkaloids, amines, nitriles, phenols, aldehydes, nitrogen oxides, and more Aromatic hydrocarbons, heterocyclic compounds, heavy metal elements, etc. Smoking can cause serious harm to human health. The advent of filter cigarettes in the 1960s has effectively reduced the amount of tar in cigarettes. Most of the current cigarettes have filters, which are generally of a single-layer structure, that is, the filter is directly wrapped with filter wrapping paper, and the filter is generally made of cellulose acetate tow. . However, the traditional filter tip i...

Patent CN 101317695 discloses an absorbent material for cigarette filters and its preparation method, that is, grapefruit peels are processed into absorbent materials for cigarette filters after acid oxidation treatment, but the method uses the whole grapefruit peels as raw materials, and does not use The outer yellow skin (also known as the oil bubble layer) of grapefruit peel is removed and directly processed, and there are the following problems: the oil bubble layer is relatively dense, basically has no adsorption capacity, and will hinder the adsorption performance of other parts of the material; during processing and storage It is easy to produce peculiar smell and miscellaneous smell, which affects the quality of the final product; the oil bubble layer shrinks after drying and the color is easily browned, and the appearance of the product is not good; and the oil bubble layer is the characteristic aroma of grapefruit---the only part where grapefruit essential oil exists, and is rich in Contains functional ingredients such as naringin, if not utilized is also a waste of resources

Moreover, it is treated with a solution containing strong acid and hydrogen peroxide, which requires high equipment requirements, dangerous operation, large amount of wastewater discharge, and a small amount of chemical substances may remain in the final material, which will have miscellaneous odors when applied to cigarette filters. , affecting the overall flavor of the cigarette
