Alkaloid composite filter tip addition material capable of reducing hydrocyanic acid in cigarette mainstream smoke

Abstract

The invention relates to filter tip addition material capable of selectively reducing the release amount of hydrocyanic acid in cigarette mainstream smoke and a preparation method thereof, new material which can effectively adsorb acidic gas can be obtained by loading plant alkaloids onto activated carbon fiber, the alkaloids are extracted from one or multiple Chinese herbal medicines of golden thread, amur corktree bark, root of Anhwei barberry and leatherleaf mahonia leaf and have anti-bacterial and anti-tumor activity, the extracted alkaloids are dissolved in 0.01%-0.1% of sodium hydroxidesolution and loaded on the activated carbon fiber by heating and stirring, then water washing and drying are further performed, and modified activated carbon fiber material containing basic groups isfinally obtained. The material is added into cigarette filter sticks and can reduce the content of the hydrocyanic acid in the cigarette mainstream smoke by more than 25%, and reduce the tar content by more than 25%, and an alkaloid additive has the characteristics of high boiling point, no smell, safety in administration and the like; simultaneously, as the selected activated carbon fiber material can stably adhere the alkaloids, the adverse effects to the organoleptic quality of cigarettes can be avoided, and the purposes of reducing harm and reducing tar can be further achieved.

Description

technical field [0001] The invention belongs to the technical field of cigarette materials, and in particular relates to a filter tip additive material for selectively reducing the release of hydrocyanic acid and tar in mainstream smoke of cigarettes, a preparation method and application thereof. Applying the material to cigarette filters can effectively reduce the content of hydrocyanic acid and tar in mainstream smoke without negatively affecting the sensory quality of cigarettes. Background technique [0002] Hydrocyanic acid (HCN) is a colorless toxic gas or liquid with a bitter almond smell. It has a low boiling point and is volatile. It exists in the form of a gas at room temperature. The threshold value of human body is only 10ppm. It is a very active inhibitor of several human respiratory enzymes. At the same time, it can combine with ferricytochrome oxidase in the human body to generate cyanide ferricytochrome oxidase and lose the function of transferring oxygen, ca...

Problems solved by technology

The absorption method mainly adopts alkali absorption and complex absorption. Since all of them are absorbed by chemical reagents, the additive has potential smoking safety problems (such as patent document CN101669678). Use trimethylaminoacetylhydrazide chloride or (2-bromoethyl) trimethyl ammonium bromide, patent document CN101524186 uses transition metal hydrochloride), the adsorption method mainly uses granular activated carbon, silica gel and metal oxides to adsorb hydrogen cyanide, but activated carbon fibers treated with alkaloids are used in cigarette filters at the same time The use of absorption and adsorption methods to reduce the release of hydrocyanic acid in mainstream cigarette smoke has not been reported, and because the appearance of activated carbon fibers is similar to that of acetate fibers, it is relatively easy to meet the requirements for use on filters, so the invention of activated carbon fibers Making alkaloid composite cigarette filter after modification
