preparation example Construction

[0017] The present invention also provides a preparation method of the activated composite adsorption air filter, comprising the following steps:

[0018] (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;

[0019] (2) After polyepichlorohydrin dimethylamine is uniformly dispersed in water, intermediate product 1 is added, ultrasonically reacted for 15-25 minutes, and then centrifugally washed and dried to obtain intermediate product 2;

[0020] (3) Roasting the intermediate product 2 at 300-500° C. for...

Abstract

The invention relates to the technical field of automobile spare parts, in particular to an activated composite adsorption air filter core and a preparation method thereof. The activated composite adsorption air filter core is prepared from the following substances by weight: 200-500 weight parts of wood pulp fiber, 20-50 weight parts of a zeolite-like imidazole framework material, 3-12 weight parts of organic titanate, 1-5 weight parts of organic silicate ester, 6-20 weight parts of polyepichlorohydrin dimethylamine, 5-15 weight parts of cetyltrimethylammonium bromide, 1-10 weight parts of apH regulator and 10-50 weight parts of a solvent. The activated composite adsorption air filter core provided by the invention has excellent catalytic performance, can effectively adsorb pollutants inthe air and achieve in situ degradation on pollutants, thus having 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 an activated composite adsorption air filter element and a preparation method thereof. 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 ca...
