Problems solved by technology

[0003] At present, the most commonly used method for the above-mentioned PM2.5 pollution is filtration, such as protection through masks, filter elements of air purifiers, etc., but simple filtration methods have certain limitations, and are generally only effective for small inorganic solid particles. Organic PM2.5 is not effective; German Trittec anti-dust screens use special materials to genera...

Embodiment 1

[0028] Take 80 grams of deionized water, add 0.5 grams of 2-methyl-1-isothiazolin-3-one, stir well, add 12 grams of arginine, and slowly add the hydrophilic polymer hydroxyethyl Cellulose (HEC) 1 g and CaCl 2 0.5 grams, after stirring for 10 minutes, add 0.3 grams of octylphenol polyoxyethylene ether, 1.2 grams of mineral oil defoamer, then use 4.5 grams of triethanolamine to adjust the pH value to be alkaline, obtain PM2.5 capture agent, and finally PM2. 5 The capture agent is dip-coated on the filter element made of non-woven fabric, and after drying at room temperature, the PM2.5 air filter element is obtained.

Embodiment 2

[0030] Take 77 grams of deionized water, add 0.3 grams of 5-chloro-2-methyl-1-isothiazolin-3-one, stir evenly, add 14 grams of histidine, and slowly add hydrophilic polymer 1.2 grams of hydroxypropyl cellulose (HPC) and 0.6 grams of NaCl, after stirring for 10 minutes, add 0.4 grams of nonylphenol polyoxyethylene ether, 1.6 grams of silicone defoamer, and then use 5 grams of triethanolamine to adjust the pH to be alkaline properties, to obtain PM2.5 capture agent, and finally spray the PM2.5 capture agent on the paper filter element, and dry it at room temperature to obtain the PM2.5 air filter element.

Embodiment 3

[0032] Take 74 grams of deionized water, add 0.2 grams of Cathone, add 15 grams of arginine after stirring evenly, slowly add 5 grams of cold water-soluble PVA (1788) and 0.8 grams of KCl during stirring, add alkane after stirring for 10 minutes Base phenol polyoxyethylene ether 0.2 gram, metal soap defoamer 0.8 gram, then use 2-amino-2-methyl-1-propanol 4 grams to adjust the pH value to be alkaline, obtain PM2.5 capture agent, finally will The PM2.5 capture agent is sprayed on the activated carbon filter element, and after drying at room temperature, the PM2.5 air filter element is obtained.

Abstract

The invention discloses a PM2.5 air filter element and a preparation method thereof, and relates to the field of air purification. The PM2.5 air filter element comprises a filter element body and a PM2.5 capturing agent sprayed and coated on the filter element body, wherein the PM2.5 capturing agent uses water-soluble neutral or weak alkaline amino acid, polypeptide or low-molecular-weight protein as main raw materials; hydrophilic polymers and salt are used as the assistance; surfactants and polyamino compound are compounded for preparation. The dust can be effectively filtered; the capturing effect on organic harmful substances and sol type PM2.5 is obvious; the air purification effect is good; the cost is low; the filter element replacement or cleaning operation is simple. The PM2.5 air filter element can be widely applied to equipment such as an automobile air filter element or air purifier; the practical values are high.

Description

technical field [0001] The invention belongs to the field of air purification and relates to a PM2.5 air filter element and a preparation method thereof. Background technique [0002] PM2.5 is a pollutant that currently affects people's lives, especially in the northern regions, where there are often reports of PM2.5 bursting. The main components of PM2.5 are organic carbon compounds, sulfates, nitrates, ammonium salts, and elements such as sodium, magnesium, calcium, aluminum, iron, lead, zinc, arsenic, and cadmium. In addition to natural processes such as natural processes, mainly human emissions, such as the burning of fossil fuels (such as coal, petroleum products), the burning of biomass (crop straw, forest fires, etc.), garbage incineration, etc., as well as dust in industrial production, road pollution, etc. dust, construction site dust, kitchen fumes, etc. In addition, some emitted gas pollutants will also be transformed into PM2.5 in the air, such as sulfur dioxid...
