preparation example Construction

[0012] The present invention also provides a kind of preparation method of described photocatalyst-based composite air cleaner, comprising the following steps:

[0013] (1) Mix organic silicate and organic titanate evenly to obtain mixed sol A, then add the zeolite-like imidazole skeleton material into mixed sol A, and ultrasonically disperse for 20 to 45 minutes to obtain mixed sol B, and then Add cetyltrimethylammonium bromide solution dropwise to the mixed sol B. After the dropwise addition, add a pH regulator to adjust the pH of the system to 5.3-6.2, and then seal the mixed system at 100-160°C for 1 ~4h, the product was washed and dried by centrifugation to obtain intermediate product 1;

[0014] (2) After uniformly dispersing polyepichlorohydrin dimethylamine in water, add intermediate product 1, then add redox graphene suspension, after ultrasonic reaction for 15-25 minutes, stir for 3-12 hours, then centrifuge, wash and dry, The intermediate product 2 is obtained;

Abstract

The invention relates to the technical field of air purification, in particular to a photocatalyst-based composite air purifying agent. The photocatalyst-based composite air purifying agent is prepared from the following substances by weight: 20-50 weight parts of an IRMOFs material, 3-12 weight parts of organic titanate, 1-5 weight parts of organic silicate, 6-20 weight parts of polyepichlorohydrin dimethylamine, 5-15 weight parts of cetyl trimethyl ammonium bromide, 5-15 weight parts of reduced graphene oxide, 1-10 weight parts of a pH regulator, and 10-50 weight parts of a solvent. The photocatalyst-based composite air purifying agent provided by the invention has excellent catalytic performance, has catalytic degradation effect on a variety of toxic and harmful substances existing in the air, and has broad application prospects in the air purification field.

Description

technical field [0001] The invention relates to the technical field of air purification, in particular to a photocatalyst-based composite air purifier. Background technique [0002] The quality of indoor air is an important factor affecting human health and thoughts and emotions. When the concentration of VOCs (volatile organic compounds) in the indoor air is too high, it is easy to cause acute poisoning. In mild cases, headache, dizziness, cough, nausea, vomiting, or drunkenness will occur; in severe cases, liver poisoning and even coma will occur soon , and some may be life-threatening. Living in a room polluted by VOCs for a long time can cause chronic poisoning, damage the liver and nervous system, cause general weakness, drowsiness, and itchy skin. Some may also cause endocrine disorders and affect sexual function; benzene and xylene can also damage the system and even cause leukemia. At present, it has been identified as a carcinogenic and teratogenic substance by t...
