Embodiment Construction
[0017] The production method of the light-weight thermal insulation wall panel for purifying air of the present embodiment has the following specific steps to prepare:
[0018] (1) Pulverize kaolin; add the pulverized kaolin to 10 times the weight of potassium acetate solution, stir magnetically at room temperature for 4 days, filter, wash, and centrifuge, and dry the centrifuged product in an electric blast drying oven for 24 hours ; Transfer the dried product to a muffle furnace and heat it up to 800°C for 4 hours, then cool it under natural conditions, ball mill it for 20 minutes, and pass through a 150-mesh sieve to obtain high-temperature expanded kaolin;
[0019] (2) Add n-butyl titanate to absolute ethanol, stir at room temperature for 4 hours, add high-temperature expanded kaolin, ultrasonically oscillate for 6 hours, filter, wash the filter cake with absolute ethanol and water for 3 times, and place in a vacuum oven at 65°C Dry for 20 hours, put the dried product into...
