High-efficiency cigarette filter tip containing nano-carbon material

Abstract

The invention provides a high-efficiency cigarette filter core containing a nano-carbon material and a cigarette filter tip prepared from the same. The cigarette filter core is characterized in that nano-carbon particles which are absorbed on fiber bundles, are subjected to surface modification and have rich active groups and high specific surface area can remove a plurality of free radicals as well as poisonous and harmful substances such as benzopyrene (a, b) and partial cigarette tar in cigarette smoke through physical and chemical absorption when the cigarette smoke passes through the fiber bundles of the filter core of the filter tip. To improve the action effect, one or more auxiliary substances can be synchronously absorbed on the fiber bundles. The filter core does not affect the unique taste and filtration aeration of cigarettes during the smoking, and can effectively remove a plurality of the poisonous and harmful substances in the smoke and improve the mouthfeel at the sametime. The filter core can be used for producing disposable cigarette filter tips, filter tips on the cigarettes, and filter tips in matroospipes to reduce the hazard caused by smoking.

Description

Technical field: [0001] The invention relates to a cigarette filter tip loaded with carbon nanometer material. In particular, it refers to a novel cigarette filter element which is simple to manufacture, environmentally friendly, non-toxic, high-efficiency, adjustable in effect and low in cost, and is especially suitable for large-scale production and the filter tip made of it. The filter element can be used as a disposable cigarette holder, and can also be used as a filter tip on a cigarette, or used in a tobacco pipe. Background technique [0002] As we all know, smoking is harmful to health. With the improvement of living standards, smokers pay more and more attention to their health. As a big smoking country, China has produced many types of cigarette filters or filter elements, some loaded with organic hydrogel materials, and some loaded with porous silicon. As for the material texture, a considerable part is loaded with carbon materials, including activated carbon, a...

Problems solved by technology

Some use special organic solvents to "dissolve" carbon materials, which is easy to load, but it is easy to cause air pollution or danger when drying, and the equipment requirements are high and the cost is high

Some solutions are to load silica, aluminosilicate, some divalent or trivalent cations, or heme on the porous carbon material. The effect is really good, but the preparation process is complicated and the cost is high. difficulty
