Abstract

The invention relates to a compound cigarette filter tip which comprises a filter tip section close to the lip end, a filter tip section close to the tobacco shred end and wrapping paper. The filter tip section close to the lip end is provided with a fiber filtration layer, the filter tip section close to the tobacco shred end is provided with a metal sintered porous filtration layer, the metal sintered porous filtration layer is a micro-filtration element made from a metal powder sintered porous filtration material, the metal powder sintered porous filtration material is prepared by using metal particles as a raw material, one-time formation is achieved through a formation technology after pretreatment, and the metal powder sintered porous filtration material is formed after sintering. The filtration material is high in filtration precision, good in filtration effect, uniform in structure and good in reproducibility, so that the compound cigarette filter tip does not deform, has the very good filtration effect on nicotine, tar, nitrosamine and other non-gaseous-phase toxic and harmful substances, does not absorb beneficial aroma components in cigarettes, is high in melting point, does not cause overburning producing cancerogens, prevents scorch and toxic smoke (produced due to scorch of the filter tip), has a good cooling effect and makes cigarettes having a cool and refreshing taste.

Description

technical field [0001] The invention belongs to the field of filter tips, in particular to a composite filter tip for cigarettes. Background technique [0002] When the smoke burns, hundreds of chemical substances harmful to the human body will be produced, including dozens of carcinogens such as nicotine, tar, and nitrosamines. The smoke formed when cigarettes burn is composed of cyanide, acrolein, formaldehyde, acetaldehyde, various organic substances, etc. The average diameter of these particles is 0.2-0.4μm, and the particle concentration is 10-1000mg / cm 3 about. At present, cigarette filters are mainly made of acetate fiber, polypropylene silk or pure paper. In order to enhance the filtering effect, the length of the filter is generally increased. Currently, the length of the filter generally ranges from 20mm to 30mm. Commonly used single-type cigarette filters have disadvantages such as insufficient filtering capacity of harmful components such as tar and nicotine, e...
