Embodiment Construction

[0031] The air purifier of the embodiment of the present invention comprises the following raw materials in proportion by weight: 50-70 parts by weight of modified activated carbon; 30-50 parts by weight of mesoporous polydivinylbenzene (PDVB); parts by weight; 0.25-0.65 parts by weight of ivy extract; and 0.55-1.25 parts by weight of aloe extract.

[0032] The raw materials used in the examples of the present invention can be purchased in the market.

[0033] Among them, mesoporous polydivinylbenzene is preferably self-synthesized by solvothermal method. Specifically, dissolve 20g of divinylbenzene (DVB) in 400ml of tetrahydrofuran (THF), then add 0.5g of azobisisobutyronitrile (AIBN), stir at room temperature for 4 hours, then transfer to a crystallization kettle, and crystallize at 110°C After cooling for 48 hours, granular mesoporous polydivinylbenzene resin was obtained. The prepared resin has a pore size of 3-5nm and a specific surface area of ​​1219m 2 / g, pore volum...

Abstract

The invention provides an air purifying agent and a preparation method thereof, and an air purification module. The air purifying agent is prepared from the following raw materials in parts by weight: 50-70 parts by weight of modified activated carbon, 30-50 parts by weight of mesoporous polydivinylbenzene, 20-25 parts by weight of a nano controlled-release carrier, 0.25-0.65 part by weight of an ivy extract and 0.55-1.25 parts by weight of an aloe extract. The invention also provides the preparation method of the air purifying agent and the air purification module having the air purifying agent. By reasonably selecting the types and ratio of the raw materials of the air purifying agent, the air purifying agent is capable of effectively reducing the content of volatile organic compounds (VOC) in the air.

Description

technical field [0001] The invention relates to the technical field of air purification, in particular to an air purifier, a preparation method thereof and an air purification module. Background technique [0002] Volatile organic compounds (volatile organic compounds, referred to as VOC) are one of the most serious organic pollutants in the air. Because of their low concentration but many types, they are generally not expressed one by one. TVOC is used to express the total quantity. TVOCs include formaldehyde, benzene, p / m / o-xylene, styrene, ethylbenzene, butyl acetate, trichloroethylene, chloroform, undecane, etc. Indoor construction and decoration materials are the main sources of TVOC in the air. [0003] The function of the refrigerator is to provide a low temperature environment to prolong the storage time of items. For the internal environment of the refrigerator, food preservation, sterilization and deodorization are mainly considered at present. Not enough atten...
