PM2.5 adsorbent and preparation method thereof

Abstract

The invention provides a PM2.5 adsorbent. The PM2.5 adsorbent is prepared from the following raw materials in parts by weight: 80-90 parts of activated carbon, 3-4 parts of sodium silicate, 0.2-0.3 part of potassium permanganate, 3-4 parts of siderite powder, 1.5-2 parts of shaddock peel powder, 1-2 parts of polyacrylate emulsion, 2-3 parts of nano zinc oxide, 1-2 parts of lactic acid, 1-2 parts of strontium carbonate, 7-11 parts of bentonite, 1-2 parts of pore-enlarging agent, 130-150 parts of 1Mol / L sodium hydroxide solution, 140-160 parts of 1Mol / L calcium chloride solution, a proper amount of water and 3-5 parts of auxiliary. The adsorbent has good adsorbability and good air purification effects, has good adsorption effects on bacteria, formaldehyde and PM2.5 in the air, can achieve the effect of catalytically oxidizing harmful substances, such as formaldehyde and the like by using nano zinc oxide, and can achieve the effect of sterilization. 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 a PM2.5 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 PM2.5...
