Problems solved by technology

Existing filter materials can effectively remove formaldehyde in the air. However, because aldehydes such as acetaldehyde and 2-nonenal are more stable than formaldehyde, it is more difficult to remove them. Poor ability
Moreover, in the existing filter materials, the capture agent used for deodorization usually has the problem that it is easy to decompose and deteriorate, so the validity period is short, and the ability to remove peculiar smell in a long-term manner is relatively poor.

preparation example Construction

[0043] An embodiment of the present invention discloses a method for preparing a deodorant, such as figure 1 As shown, the preparation method includes:

[0044] Step 1: prepare an aqueous solution containing at least sulfamic acid; mix at least sulfamic acid and water in a certain proportion to obtain an aqueous solution, and the mixing can be achieved by stirring or ultrasonication.

[0045] Step 2: The aqueous solution is attached to the solid carrier by spraying or dipping, and the solid carrier is dried to obtain a deodorant. Specifically, the aqueous solution can be sprayed onto the fixed support by a spraying machine, or the solid support can be immersed in the aqueous solution for a period of time, so that the aqueous solution can be attached to the solid support. The solid support to which the aqueous solution is attached can be placed in an oven or drying oven for drying.

[0046] The deodorant prepared by the method in this embodiment can effectively remove aldehyd...

Embodiment 1

[0071] The coal-based columnar activated carbon with a carbon tetrachloride adsorption value of 65% and a diameter of 2 mm was selected as a solid support, and the solid support was immersed in an aqueous solution with a concentration of sulfamic acid of 3%, the immersion time was not less than one minute, and then passed through The activated carbon is separated from the aqueous solution by centrifugal separation, and the deodorant can be prepared by hot air drying at a drying temperature of 60° C. and a moisture content of less than or equal to 12%.

Embodiment 2

[0073] The coal-based columnar activated carbon with a carbon tetrachloride adsorption value of 65% and a diameter of 2 mm was selected as the solid support, and the solid support was immersed in an aqueous solution with a sulfamic acid concentration of 3% and a 2-imidazolidinone concentration of 2%. The immersion time is not less than one minute, and then the activated carbon is separated from the aqueous solution by centrifugal separation, and then dried with hot air. The drying temperature is 60 ° C, and the moisture content is less than or equal to 12%.

Abstract

The invention discloses a preparation method of a deodorant, the deodorant and a deodorization filter screen. The preparation method comprises the following steps: step 1, preparing an aqueous solution at least containing sulfamic acid; and 2, attaching the aqueous solution to the solid supporter in a spraying or dipping manner, and drying the solid supporter to obtain the deodorant. The deodorant prepared by the method can effectively remove aldehydes in air, has a lasting effect, and is not easy to become sour.

Description

technical field [0001] The invention belongs to the technical field of fine chemicals, and particularly relates to a preparation method of a deodorant, a deodorant and a deodorant filter. Background technique [0002] In the face of deodorization problems such as modern home decoration and construction, the deodorization effect and effectiveness of gaseous pollutant filter materials are very important. Existing filter materials can effectively remove formaldehyde in the air, but because aldehydes such as acetaldehyde and 2-nonenal are more stable than formaldehyde, it is more difficult to remove, and existing filter materials often remove such aldehydes. Poor ability. Moreover, in the existing filter media, the scavenger used for deodorization usually has the problem of being easily decomposed and deteriorated, so the validity period is short, and the long-term odor removal ability is poor. SUMMARY OF THE INVENTION [0003] In view of the above problems, the present inve...
