Embodiment 1

[0023] Cellulose Amination and Cellulose Pelleting

[0024] Add 10g of cellulose and 42g of urea into the reactor for stirring, add 300ml of water and 600ml of xylene, heat at 110°C to separate the water, react for 5 hours, and then raise the temperature. Wash with water, wash with alcohol, separate liquid, remove all organic solvents, and generate cellulose particles. Infrared characterization shows that there are amino groups on the modified cellulose. Take 30-40 mg of the prepared modified cellulose balls and add them to the cigarette filter, analyze the cigarette smoke, and reduce the harmful components of phenols in the cigarette smoke by 19%. Reduce cigarette tar by 2.7mg.

Embodiment 2

[0026] Preparation of cellulose spheres

[0027] Add 10g of cellulose, 42g of urea and 2g of sodium carbonate into the reactor and stir, add 300ml of water and 600ml of cyclohexane, heat at 110°C to separate the water, react for 5 hours, and then raise the temperature. Wash with water, wash with alcohol, separate liquid, remove all organic solvents, and generate cellulose particles. It looks like figure 1 . Add 30-40 mg of the prepared cellulose balls into the cigarette filter, analyze the cigarette smoke, and reduce the cigarette tar by 2.0 mg.

Embodiment 3

[0029] Preparation of cellulose spheres

[0030] Add 10g of cellulose and 2g of calcium carbonate into the reactor and stir, add 300ml of water and 600ml of xylene, heat at 110°C to separate the water, react for 5 hours, then raise the temperature, and remove 90% of the water by dividing the water. Wash with water, wash with alcohol, separate liquid, remove all organic solvents, and generate cellulose particles. Add 30-40 mg of the prepared cellulose balls to the cigarette filter, analyze the cigarette smoke, and reduce the total particle phase of the cigarette by 1.9 mg.

Abstract

The invention discloses tar and harm reducing cellulose balls for cigarette filter tip and preparation thereof. Through mutual winding of cellulose fibers, mass ball-shaped cellulose is caked. The groups of the modified fibers in a cellulose forming ball process achieve the purpose of chemically adsorbing harmful components of the cigarette smoke; cellulose balls with high adsorption capability are added into an acetate fiber filter stick to effectively reduce the harmful components in the cigarette smoke; and the ball-shaped cellulose can effectively adsorb the total particulate matter in the cigarette smoke.

Description

technical field [0001] The technical field relates to a kind of cellulose spherical particles which can effectively reduce harmful components in cigarette smoke and have adsorption effect when applied to cigarettes, and a preparation method thereof. Background technique [0002] Since the 1950s, harm reduction and tar reduction technology has always been the focus, hotspot and difficulty in the research of the international tobacco industry. Since the 1990s, there has been a new wave of tobacco control in the world. Some major developed countries in the world have successively imposed strict restrictions on the tar, nicotine and CO content of commercially available cigarettes. Chinese-style cigarettes are the development direction of Chinese cigarettes proposed in a timely manner under the background of China's accession to the WTO and the "Framework Convention on Tobacco Control" in combination with my country's national conditions. It is necessary to focus on Chinese-styl...
