Problems solved by technology

[0003] The traditional method of eliminating indoor harmful gases and odors is mainly the adsorption method, which uses some substances with adsorption capacity to adsorb formaldehyde, ammonia, benzene, toluene and other harmful components in the indoor air to achieve the purpose of eliminating pollution. Physical adsorption is the main method, which has the problems of poor adsorption selectivity and long processing time; and if the adsorption material is not post-treated in time, the temperature rises or the storage time is long, harmful gases such as formaldehyde will be released again, polluting surroundings

Embodiment 1

[0017] (1) Preparation of water-absorbent resin

[0018] Calculated in parts by weight, fully disperse 3 parts of sodium acrylate, 5 parts of sodium maleate, and 3 parts of ethyl dimethylaminoacrylate into 35 parts of water to form a mixture, drop the resulting mixture into 50 parts of silicone oil and heat up to 75 Fully react at ℃, filter after reaction, and the filter cake is water-absorbent resin;

[0019] (2) Calculated in parts by weight, fully disperse 6 parts of sodium perchlorate, 10 parts of sodium glycerophosphate, 4 parts of potassium bisulfate, and 16 parts of glycerin in 32 parts of water, and add to it in step (1) to obtain 32 parts of the water-absorbent resin, let stand until the water-absorbent resin is fully absorbed, and then filter the water-absorbent resin to obtain a loaded air purifier.

Embodiment 2

[0021] (1) Preparation of water-absorbent resin

[0022] Calculated in parts by weight, fully disperse 4 parts of acrylic acid, 5 parts of sodium maleate, and 3.5 parts of styrene into 30 parts of water to form a mixture, drop the resulting mixture into 35 parts of silicone oil, and then raise the temperature to 75°C to fully react. After filtering, the filter cake is the water-absorbing resin;

[0023] (2) Calculated in parts by weight, fully disperse 9 parts of potassium perchlorate, 10 parts of sodium glycerophosphate, 5 parts of potassium bisulfate, and 20 parts of propylene glycol in 26 parts of water, and add the water-absorbing powder obtained in step (1) to it. 30 parts of resin, let stand until the water-absorbing resin is fully absorbed, and then filter out the water-absorbing resin to obtain a loaded air purifier.

Abstract

The invention belongs to the technical field of air purification treatment, and particularly relates to a supported air purifying agent and a preparation method thereof, wherein the air purifying agent comprises perchlorate, sodium glycerophosphate, bisulfate, an organic solvent, a water-absorbing resin and water, can adsorb formaldehyde, ammonia gas, benzene and other harmful gases in the air, performs chemical treatment on part of the harmful gases, and has significantly improved elimination capacity on multiple harmful components.

Description

technical field [0001] The invention belongs to the technical field of air purification treatment, and in particular relates to a loaded air purifier and a preparation method thereof. Background technique [0002] Some toxic gases such as formaldehyde and benzene will be produced during indoor decoration. If the indoor concentration is too high, it will cause great harm to the human body, especially for pregnant women, children and the elderly. [0003] The traditional method of eliminating indoor harmful gases and odors is mainly the adsorption method, which uses some substances with adsorption capacity to adsorb formaldehyde, ammonia, benzene, toluene and other harmful components in the indoor air to achieve the purpose of eliminating pollution. Physical adsorption is the main method, which has the problems of poor adsorption selectivity and long processing time; and if the adsorption material is not post-treated in time, the temperature rises or the storage time is long, ...
