Embodiment 1

[0025] Disperse 10g of amino-functionalized multi-walled carbon nanotubes evenly in water, then slowly add 3g of chitosan to it, ultrasonically disperse it for 5 minutes, transfer it to a watering can with pressure, and evenly spray it on the surface of 87g shredded tobacco. The shredded tobacco was dried at 60° C. for 6 hours to obtain the shredded tobacco of the corresponding carbonaceous material. Then roll the shredded tobacco into a cigarette filter base rod, and compound it with the cellulose acetate base rod at a ratio of 10:15 to form a cigarette filter rod. The tobacco material part is placed in the shredded tobacco section, and the length is 10 mm.

Embodiment 2

[0027] Disperse 10g of amino-functionalized multi-walled carbon nanotubes evenly in water, then slowly add 3g of xanthan gum to it, ultrasonically disperse it for 5 minutes, transfer it to a watering can with pressure, and evenly spray it on the surface of 85g of expanded tobacco stems, The treated expanded shredded tobacco stems were dried at 80° C. for 3 hours to obtain the corresponding expanded shredded tobacco stems of carbonaceous material. Then the expanded shredded tobacco stem is rolled into a cigarette filter rod base rod, which is compounded with the acetate fiber base rod at a ratio of 10:15 to form a cigarette filter rod, and the tobacco material part is placed in the shredded tobacco section with a length of 10 mm.

Embodiment 3

[0029] Disperse 15g of multi-walled carbon nanotubes evenly in water, then slowly add 5g of guar gum to it, ultrasonically disperse for 10 minutes, transfer to a watering can with pressure, spray evenly on the surface of 80g of shredded tobacco stems, and put the processed The shredded tobacco stems were dried at 80° C. for 3 hours to obtain shredded tobacco stems of corresponding carbonaceous materials. Then the shredded tobacco stem is rolled into a cigarette filter rod base rod, which is composited with the acetate fiber base rod at a ratio of 10:15 to form a cigarette filter rod.

Abstract

The invention discloses a cigarette filter tip reducing carbonyl compounds in the cigarette mainstream smoke and a manufacture method thereof. The filter tip comprises at least one fiber filtering bar unit segment and at least one carbonyl reducing filtering bar unit segment in a compounded manner. The manufacture method includes dispersing carbon material in water through ultrasonic, adding adhesive material for ultrasonic dispersion, spraying the obtained dispersion mixed liquid to the surface of tobacco material, drying, and obtaining the compound material; manufacturing a filtering bar unit segment through the compound material, and manufacturing the filter tip with the fiber filtering bar unit segment in a compounded manner. The filter tip is capable of reducing the carbonyl compounds in the cigarette mainstream smoke effectively and selectively, and the cigarette taste and quality are not influenced; the filter tip manufacture method is simple and low in cost, and the industrial production can be met.

Description

technical field [0001] The invention relates to a cigarette filter capable of reducing aldehyde compounds in cigarette mainstream smoke and a preparation method thereof, belonging to the technical field of cigarette filter preparation. Background technique [0002] Part of the volatile small molecular aldehyde compounds produced during the combustion of cigarettes, such as formaldehyde, acetaldehyde, propionaldehyde, acrolein, crotonaldehyde, etc., may bring bad smell to cigarettes and have adverse effects on consumers' health , among which substances such as formaldehyde, acrolein and crotonaldehyde can cause lung diseases. Therefore, reducing as much as possible the aldehyde compounds in the smoke that have adverse effects on the quality of cigarettes has always been the direction of efforts of tobacco researchers. [0003] In order to increase the smoking safety of cigarettes, the research in the field of reducing tar and harm of cigarettes is constantly deepening. Ordi...
