Adsorbent used for face masks and preparation method thereof

Abstract

The invention provides an adsorbent used for face masks. The adsorbent is prepared from the following raw materials in parts by weight: 80-90 parts of activated carbon, 1-1.5 parts of sesbania cannabina powder, 2-3 parts of expanded graphite, 130-150 parts of 1 Mol / L sodium hydroxide solution, 140-160 parts of 1 Mol / L calcium chloride solution, 1-2 parts of organic silica gel, 1-1.6 parts of lanthanum oxide, 2-3 parts of aluminium hydroxide, 10-15 parts of kaolin, 1-2 parts of cellulose sodium, 1-2 parts of lignin, 2-3 parts of citric acid, 2-3 parts of iron oxide, 0.5-0.8 part of sodium silicate, a proper amount of water and 3-5 parts of auxiliary. The adsorbent has good barrier effects on bacteria and PM2.5 in the air, can be used for catalytically oxidizing harmful substances, such as formaldehyde and the like, can be also used for sterilization, does not affect the air permeability, and is suitable for hazy weathers at present. By using the auxiliary, skin allergy can be prevented, refreshment can be achieved, and the filtration performance can be improved.

Description

technical field [0001] The invention relates to the field of adsorbents, in particular to an adsorbent for masks 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 an adsorbe...
