Problems solved by technology

[0002] In recent years, the smog weather has become more and more serious, and PM2.5 has seriously exceeded the standard. The smog contains a large number of germs and dust, which poses a great threat to people's health. The current ordinary mask adsorbent is basically activated carbon. , but the adsorption and filtration effect of activated carbon on particulate pollutants is limited, and various organic waste gas pollutants in the atmosphere are gradually increasing. Activated carbon adsorbents cannot decompose and remove these pollutants. Even if they are adsorbed on masks, they will have an impact on human health. Therefore, In order to protect people's health, it is necessary to improve the mask adsorbent

Abstract

The invention relates to an anti-haze adsorbent which comprises the following materials in parts by weight: 80-90 parts of activated carbon, 0.2-0.3 part of ammonium bicarbonate, 6-8 parts of zeolite powder, 0.5-0.8 part of triene tetramine, 2-3 parts of tetragonal sulfate lepidocrocite, 10-15 parts of molecular sieve 5A, 2-3 parts of a polyvinyl acetal glue solution, 2-4 parts of coal ash, 2-4 parts of carboxymethylcellulose, 1-1.3 parts of allyl cyclodextrin, 130-150 parts of a 1 Mol / L sodium hydroxide solution, 140-160 parts of a 1 Mol / L calcium chloride solution, a proper amount of water, and 3-5 parts of an assistant. The adsorbent has an excellent adsorption effect on harmful gases, peculiar-smell air, and smoke of cigarettes, can inhibit bacteria at the same time, has excellent adsorbing and blocking effects on PM2.5, has an excellent anti-haze effect, and is suitable for a respirator. The adsorbent provided by the invention can prevent skin allergy, helps to refresh, and improves the filtering performance.

Description

technical field [0001] The invention relates to the field of adsorbents, in particular to an anti-smog adsorbent and a preparation method thereof. Background technique [0002] In recent years, the smog weather has become more and more serious, and PM2.5 has seriously exceeded the standard. The smog contains a large number of germs and dust, which poses a great threat to people's health. The current ordinary mask adsorbent is basically activated carbon. , but the adsorption and filtration effect of activated carbon on particulate pollutants is limited, and various organic waste gas pollutants in the atmosphere are gradually increasing. Activated carbon adsorbents cannot decompose and remove these pollutants. Even if they are adsorbed on masks, they will have an impact on human health. Therefore, In order to protect people's health, it is necessary to improve the mask adsorbent. Contents of the invention [0003] The object of the present invention is to provide a kind of ...
