Example Embodiment
[0023] Example 1:
[0024] 1) Add 20 grams of acidified activated carbon to 10 ml SOCl 2 In the liquid and reflux for 2 hours at 40 degrees Celsius, acyl chloride activated carbon will be obtained;
[0025] 2) Put 1 gram of nano-manganese dioxide into 100 ml of ethanol / water (the volume ratio of ethanol to water is 4:1) dispersant and stir for 30 minutes to obtain a manganese dioxide solution;
[0026] 3) Add 0.02 grams of aminosilane coupling agent to the manganese dioxide solution to obtain a nano-manganese dioxide solution modified by the silane coupling agent;
[0027] 4) Add the above acyl chloride activated carbon to the nano-manganese dioxide solution modified by the silane coupling agent, stir for 1 hour, and then vacuum filter;
[0028] 5) The product of step 4) is vacuum-dried at 120 degrees Celsius for 12 hours to obtain a long-lasting formaldehyde-removing air purifier filter element material.
[0029] Put the obtained filter element material and the same quality of activate...
