Embodiment 1

[0021] Prepare CFRs:

[0022] Add 3.68g of curcumin, 30mL of dimethylformamide, 20mL of triethylamine, and 5mL of 37% formaldehyde into the three-necked flask, and heat at 80°C for 24 hours. A brown reaction solution was obtained, and a brown precipitate was obtained after cooling; it was washed with deionized water and dried in vacuum for 6 hours.

Embodiment 2

[0025] Under the action of ultrasound, add 0.1g of CFR to 50g of deionized water. After the dispersion is uniform, add 100g of sodium alginate to the solution and stir evenly; move the wet granules into an oven, bake at 110°C for 4 hours, cool to room temperature naturally, sieve to remove the fine powder and take 40-60 mesh granules to wait use.

[0026] The prepared additive is added to the cigarette filter tip at 40 mg / piece, and the smoke test results show that the material can effectively reduce the phenol content in the smoke by 15.3%.

Embodiment 3

[0028] Under the action of ultrasound, add 0.5g CFR to 50g deionized water. After the dispersion is uniform, slowly add the solution to 100g of sodium alginate and stir evenly at the same time; move the wet particles into the oven, bake at 100°C for 6 hours, cool to room temperature naturally, sift to remove the fine powder and take 40-60 mesh Granules are ready to use.

[0029] The prepared additive is added to the cigarette filter tip at 40 mg / piece, and the smoke test results show that the material can effectively reduce the phenol content in the smoke by 25.1%.

Abstract

The invention discloses a cigarette filter additive capable of lowering phenol content in mainstream smoke and a preparation method and application of the cigarette filter additive. The cigarette filter additive is a composite formed by loading curcumin formaldehyde resin on a solid carrier. The preparation method includes dispersing the curcumin formaldehyde resin in water and adding in the carrier for soaking prior to filtering and drying to obtain the cigarette filter additive. The cigarette filter additive is good in chemical stability and safe to human bodies, the phenol content in the mainstream smoke can be lowered effectively by adding the cigarette filter additive to a cigarette filter; in addition, the preparation process and operation of the cigarette filter additive are simplified, and industrial production is satisfied.

Description

technical field [0001] The invention relates to a cigarette filter rod additive capable of reducing phenol content in mainstream smoke, a preparation method and application thereof, and belongs to the field of cigarette manufacturing. Background technique [0002] Cigarette combustion is a complex reaction. As one of the main components in smoke, there are 40 kinds of phenolic compounds, the most important of which include phenol and catechol. The phenolic compounds in cigarette smoke mainly come from the polyphenols in tobacco leaves. Cleavage of phenolic compounds (chlorogenic acid and rutin), there is evidence that the presence of phenolic substances can significantly increase the carcinogenic activity of polycyclic aromatic hydrocarbons, especially phenol, o, m, hydroquinone, o, m, p Cresols are the most harmful phenols. Among them, catechol in the smoke condensate can assist in promoting cancer, and some phenols have a strong stimulating effect on the skin and respirato...
