Embodiment 1

[0026] Take the rush stem pith, after removing impurities and dust, soak in 0.5% chitosan aqueous solution by weight for 3 hours, filter to dry, then put the filtered rush stem pith in the drying equipment, and dry at 102±2°C After 2 hours, crush and sieve to obtain the required filter material with 20-40 mesh. The filter material is added into the filter rod in an amount of 5mg / 10mm to prepare a binary composite filter rod. When the binary compound filter rod is applied to cigarettes, it has the effect of reducing the irritation of cigarettes, and at the same time reduces tar by 40%, and reduces the hazard evaluation index of cigarettes by 15%.

Embodiment 2

[0028] Stem pith and corn pith are taken in a ratio of 1:1, and soaked in a polymer solution after removing impurities and dust. The polymer solution is prepared from 5% by weight water-soluble starch and polyvinylpyrrolidone aqueous solution according to the mass fraction ratio of 1:2. The soaking time is 5 hours, then the stem pith material is filtered and dried in a drying oven at 102±2°C for 1 hour, then the dried stem pith material is crushed and sieved to obtain the required filter material of 80-100 mesh. The filter material is added into the filter rod material according to the addition amount of 3mg / 10mm to prepare a binary composite filter rod. Applying the binary composite filter tip to cigarettes has no negative impact on the sensory quality of the cigarettes, while reducing tar by 20% and reducing the hazard evaluation index of cigarettes by 8%.

Embodiment 3

[0030] Take sunflower stem pith and green pod leaf stem pith according to the ratio of 1:2, after removing impurities and dust, soak in 20% gum arabic aqueous solution for 0.5h, filter, dry at 102±2°C for 3h, pulverize, pass through Sieve to obtain the desired filter material of 40-60 mesh. The filter material is added to the filter rod material in an amount of 10mg / 10mm to prepare a binary composite filter rod. Applying the binary composite filter tip to cigarettes has no negative impact on the sensory quality of the cigarettes, and simultaneously reduces tar by 56%, and reduces the hazard evaluation index of cigarettes by 30%.

Abstract

The invention relates to a preparation method of a natural filtering material for a filter tip. The preparation method comprises the following steps: taking the plant stem pith material, and soaking in a high-molecular solution, wherein the soaking time is 0.5-5 hours, and the high-molecular solution is the solution prepared by soaking one or more substances of chitosan, Arabic gum, peach gum, polyvinyl pyrrolidone and water-soluble starch into water according to the weight percentage of 0.5-20%; and then filtering, placing into an oven of 102+ / -2 DEG C to dry, wherein the drying time is 1-3 hours; and finally crushing the dry stem pith material into fine particles, sieving through a 20-100 meshed sieve, obtaining the natural filtering material for a filter tip. The filtering material prepared by the invention can be matched with the Chinese cigarette suction style, and has small negative influence to the Chinese cigarette and relatively higher filtering efficiency of smoke harmful substances.

Description

technical field [0001] The invention belongs to the technical field of cigarette material preparation, and in particular relates to a filter material used for a cigarette filter tip and a preparation method of the filter material. Background technique [0002] With the development of "low-tar, low-hazard" cigarettes, research on filter materials for cigarette composite filters has attracted more and more attention, but there are very few filter materials that are actually used in Chinese-style flue-cured cigarettes. The matching problem of cigarette smoking style, on the other hand, is the problem of the balance of the filter material itself. Such as activated carbon, which has a great influence on the style of Chinese cigarettes; inorganic materials such as diatomaceous earth and sepiolite, in addition to having many negative effects on cigarette production, will also cause cigarettes to produce some dusty smell and irritation; some natural materials such as tea powder Org...
