Embodiment 1

[0018] With 2g of solid organic amine, adopt chemical coating method to make solid organic amine active component. Then, the solid organic amine active component was ground into 100-mesh powder, 183 g of aqueous pressure-sensitive adhesive solution was added, and fully stirred to form an active component emulsion. Burn 17g of 4mm columnar coal-based activated carbon at 105-110°C for 1 hour for pretreatment, then completely impregnate the activated carbon into the active component emulsion, and stir while adding. After being fully impregnated, filter out the activated carbon and dry it at 60°C.

Embodiment 2

[0020] 10g of solid organic amine was prepared into solid organic amine active component by chemical coating method. Then the solid organic amine active component was ground into 300-mesh powder, 183g of aqueous pressure-sensitive adhesive solution was added, and fully stirred to form an active component emulsion. Use a high-pressure spray gun to spray the active ingredient emulsion at 5 g / dm 2 Spray evenly on a 0.5cm thick sponge filter and dry at 70°C.

Embodiment 3

[0022] 10g of solid organic amine was prepared into solid organic amine active component by chemical coating method. Then the solid organic amine active component was ground into 300-mesh powder, 183g of aqueous pressure-sensitive adhesive solution was added, and fully stirred to form an active component emulsion. Use a high-pressure spray gun to spray the active ingredient emulsion at 2g / dm 2 Spray evenly on a 0.2cm thick synthetic fiber filter, and dry at 60°C. Fold the filter screen into a V-shaped structure to make a filter, increase the ventilation area per unit area of ​​the filter structure, reduce wind resistance, and improve purification efficiency.

[0023] test

[0024] It is 120m that the V-shaped structure filter that embodiment 3 is made is packed into air volume 3 / h air purification device, put 25m 3 Tested in an airtight cabin (equivalent to an ordinary bedroom). The initial formaldehyde gas concentration is 1.00mg / m 3 , the hydrogen chloride gas concent...

Abstract

The invention relates to a preparation method of a gas purification material, which can eliminate aldehydes, acidic gases and benzene series in air simultaneously. The preparation method comprises the following steps of: (1) preparing granular or powdered solid organic amine active ingredient by adopting a chemical coating method; (2) grinding the active ingredients into powder; (3) mixing the active ingredients with aqueous pressure-sensitive adhesive solution to prepare active ingredient emulsion; and (4) attaching the active ingredient emulsion on a carrier and drying. The invention can eliminate aldehydes, acidic gases and benzene series in the air simultaneously, has very remarkable purification effect and is convenient to use and very suitable for industrial and civil popularization.

Description

technical field [0001] The invention relates to a preparation method of a gas purification material, which can simultaneously remove aldehydes, acid gases and benzene series in the air. Background technique [0002] In recent years, with the improvement of living standards and the enhancement of health awareness, the problem of indoor and outdoor air pollution has attracted more and more attention. At the same time, the environmental protection industry related to gas pollution purification has also developed rapidly. Ordinary gas purification materials are only effective for one or one type of polluting gases, and the types of indoor or outdoor polluting gases are often very complex. It is necessary to purify several of the most common pollutants such as aldehydes, benzene series, and acid gases at the same time. It is necessary to mix several purification materials with different functions, which is not only troublesome to operate, but also may affect each other and reduce...
