[0015] The present invention also provides a preparation method of the activated composite adsorption type air purifier, comprising the following steps:
[0016] (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;
[0017] (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;
[0018] (3) Calcining the intermediate product 2 at 300-500...
