Problems solved by technology

[0005] However, the time for the smoke to pass through the filter is very short, and at the same time, the components in the smoke are mixed together and pass through the filter in the form of aerosol. The existing additives cannot fully contact with the smoke, which affects the adsorption efficiency and capacity of harmful components.
For phenol, the existing additives cannot quickly and selectively absorb. At the same time, in addition to improving the taste or irritation, the existing additives cannot effectively remove harmful substances in the smoke, especially for phenol, and the preparation Complex process

Embodiment 1

[0025] The preparation method of the composite material that reduces the amount of phenol release in the flue gas of the present embodiment is carried out as follows:

[0026] In 50g of 4wt% polyethylene glycol-water solution, add 3g of coconut shell activated carbon, ultrasonic 10min, take out and drain, then join in the configured 60g of 5wt% polymer-water solution, the polymer is molecular weight of 10000 Vinylpyrrolidone-maleic acid copolymer, after ultrasonication for 5 minutes to make it uniform, take it out and dry it, which is the required polyvinylpyrrolidone-activated carbon composite material product.

[0027] 50 mg of the above composite material was added to the cigarette tip rod.

[0028] Smoke composition analysis was carried out on the prepared cigarettes, wherein the blank sample was a cigarette without any materials added, and the control sample was a cigarette directly added with the same weight and the same amount of activated carbon.

[0029] It can be se...

Embodiment 2

[0033] The preparation method of the composite material that reduces the amount of phenol release in the flue gas of the present embodiment is carried out as follows:

[0034] In 100g of 1wt% fatty acid sodium-triacetin solution, add 1g of sawdust activated carbon, ultrasonic 5min, take out and drain, then join in the configured 100g of 5wt% polyvinylpyrrolidone-triacetin solution, The molecular weight of polyvinylpyrrolidone is 1000. After ultrasonication for 5 minutes to make it uniform, take it out and dry it, which is the required polyvinylpyrrolidone-activated carbon composite material product.

[0035] 100 mg of the above composite material was added to the cigarette tip rod.

[0036] The smoke components of the prepared cigarettes were analyzed, and the results are shown in Table 2. The blank sample was a cigarette without any materials added, and the control sample 2 was a cigarette directly added with the same weight of activated carbon.

[0037] It can be seen from ...

Embodiment 3

[0041] The preparation method of the composite material that reduces the amount of phenol release in the flue gas of the present embodiment is carried out as follows:

[0042] Add 10g of walnut shell activated carbon in the 30wt% Span and sodium lauryl sulfate-ethanol solution of 100g, wherein, Span is 15g, sodium lauryl sulfate is 15g, ultrasonic 20min, take out and drain, then Add it to the prepared 100g of 10wt% polymer-ethanol solution, the polymer is polyvinylpyrrolidone with a molecular weight of 1,000,000, after ultrasonication for 30 minutes, take it out and dry it, which is the required polyvinylpyrrolidone-activated carbon composite material product .

[0043] 10 mg of the above composite material was added to the cigarette tip rod.

[0044] The smoke components of the prepared cigarettes were analyzed, and the results are shown in Table 3. The blank sample was a cigarette without any materials added, and the control 3 samples were cigarettes directly added with the...

Abstract

The present invention relates to a composite material for reducing phenol emission from flue gas and a preparation method and application thereof. The preparation method comprises the following stepsof (1), preparation of polymer solution, (2), preparation of surfactant solution and (3), preparation of composite materials. The composite material for reducing phenol emission from flue gas is combined with PVP and activated carbon, the contact area between the PVP and the flue gas is effectively improved, the adsorption efficiency and capacity of phenol in the flue gas by the composite materialfor reducing phenol emission from flue gas are improved. The phenol content in the flue gas is quickly and selectively reduced, and the phenol content in the flue gas can be obviously reduced, and obvious influence on the smoking of cigarettes is not produced, and at the same time the irritation is improved. Besides, the composite material for reducing phenol emission from flue gas is simple in preparation and low in cost.

Description

technical field [0001] The invention relates to a composite material, in particular to a composite material for reducing the release of phenol in smoke, and also relates to a preparation method and application thereof, belonging to the field of tobacco. Background technique [0002] Since the early 1950s, when the Royal Society of Medicine first reported the official report on the health hazards of smoking, smoking and health issues have always been highly valued by governments, the tobacco industry and the medical profession. In recent years, with the active promotion of the World Health Organization (WHO), many governments and various anti-smoking groups, the "Framework Convention on Tobacco Control" formulated by WHO not only stipulates that governments should adopt and implement effective legislation, administration and Other measures prevent and reduce tobacco consumption, nicotine addiction and exposure to tobacco smoke, etc., and also require restrictions on the conte...
