Embodiment 1
[0019] (1) First aminate the zeolite molecular sieve: put a 250ml three-neck flask into a constant temperature water bath, take 100ml of toluene into the three-necked flask, weigh 10ml of silane coupling agent KH-550, and put 10g of zeolite molecular sieve into In the flask, stir at room temperature for 15 minutes to fully dissolve it in toluene. Then the water bath was heated to 85°C, reacted for 4h and condensed to reflux. After the reaction, the reaction solution was cooled to room temperature, then centrifuged and washed with toluene for 3 times, and the final centrifuged product was placed in a drying oven at 35° C. for 10 h in vacuum to obtain an aminated zeolite molecular sieve.
[0020] (2) Synthesis of air-purifying functional filler: fix the three-necked bottle on an iron stand with a stirrer, add 1g of salicylic acid and 1g of citric acid into the three-necked bottle, then add 80ml of DMF to the beaker, start the stirrer, The rotating speed is 260r / min, after stirr...
