Adsorption material for cigarette filter-tip and preparation method thereof

Abstract

The invention discloses an adsorbing material for cigarette filter and the preparation method. Fresh grapefruit peel is prepared and cleaned, and impurities and dirt are removed. The grapefruit peel is soaked in hydrogen chloride solution and added into hydrogen peroxide accounting for 0.1 to 2 permillage of the solution with the concentration of 30 percent, and then heated to the temperature ranging from 40 to 50 DEG C, kept at constant temperature for 8 hours, and filtered. After being cleaned by clear water, the grapefruit peel is dried under the condition of 50 to 60 DEG C for 5 to 8 hours, comminuted to form fine particles and filtered through a sieve with 20 to 80 meshes, thus obtaining the absorbing material required. Since natural plant material is adopted, the prepared absorbing material has quite good tenacity, which is beneficial to the formation of a filter stick and the production of cigarettes, and does not cause the wear of equipment; the absorbing particles has loose and porous cavum structure and comparatively large specific surface area, and is applied to the cigarette filter so as to be capable of effectively removing injurious ingredients, such as tar, NNK, benzo(a)pyrene, etc.

Description

technical field [0001] The invention belongs to the technical field of cigarette production and relates to a cigarette filter, in particular to a novel adsorption material for the cigarette filter. At the same time, the invention also relates to a preparation method of the adsorption material. Background technique [0002] At present, the international cigarette market is showing a tendency to accelerate the development of "low-tar, low-hazard" cigarettes, while my country clearly stated in 2005 that the tar content of national famous and high-quality cigarettes has been reduced to about 12mg / stick on average, and cigarettes higher than 15mg / stick are not Allowed to enter the market for sale. At the same time, the domestic tobacco industry has further clarified the substances in the Hoffman list. The National Bureau pointed out that CO, HCN, NNK, NH 3 The release of seven harmful components, benzo[a]pyrene, phenol and crotonaldehyde, can effectively characterize the biohaza...

AI Technical Summary

Problems solved by technology

[0009] First, due to the high strength of these materials, in the process of cutting the filter rod after forming and cigarette rolling and cutting, the wear and tear on the cutting blade is relatively large, resulting in an increase in equipment costs and downtime accidents

[0010] Second, due to the lack of toughness of these materials, it is easy to generate dust due to abrasion during cigarette manufacturing and transportation

On the one hand, these dusts will enter the mouth of smokers with the smoke, endangering the health of smokers; on the other hand, because the aroma style of Chinese-style flue-cured tobacco cigarettes is mainly elegant, these dusts are mixed in the smoke, causing cigarettes to produce varying degrees of Miscellaneous odors, such as "earth smell", "charcoal smell", etc.

[0011] Third, in the process of cigarette production, packaging, and transportation, some adsorbent materials will fall off from the filter tip and enter the shredded tobacco, which will affect the combustion performance and state of the cigarette, and cause instability in the smoking quality of the cigarette.

[0012] Fourth, the unqualified cigarettes that appear in the cigarette production process are easily polluted by the above-mentioned adsorbent materials during the recycling process. Therefore, the unqualified products of composite filter stick cigarettes made of these adsorbent materials are generally not recycled. Waste disposal, resulting in loss of raw materials

[0013] The existence of the above problems has seriously restricted the wide application of composite filters on Chinese cigarettes
