The invention discloses a preparation method of a wear-resisting formaldehyde adsorption material. The preparation method comprises the following steps: (1) weighing hydroxypropyl ammonium hydrogen carbonate, ethylene glycol, leucine, bentonite, ground quartz, aluminum oxide, ammonium hydrogen carbonate, menthol and tetrahydrofuran and adding into a reaction kettle provided with a stirrer and a thermograph; raising the temperature to 40 DEG C-60 DEG C and stirring for 30min-50min; adding de-ionized water and continually stirring for 30min-50min; (2) weighing diatomite, rock wool, magnesium oxide and Portland cement and drying at a constant temperature of 90 DEG C-110 DEG C, and mixing a mixture with a product which is uniformly stirred in the step (2); and (3) putting the product mixed in the step (2) into a vacuum drying box and drying at 30 DEG C-40 DEG C for one night to obtain the wear-resisting formaldehyde absorption material. The formaldehyde removing rate of the product is up to 97.8%-99.5%; the product has the advantages of high wearing resistance, long service life, capability of being repeatedly utilized, and environmental protection, wide adsorption speed and wide adsorption range; after the product is put into a sealed space with the formaldehyde content of 400microg/m<3>-500microg/m<3> for 24h-48h, the concentration of formaldehyde is 2 microg/m<3>-8 microg/m<3>; and the preparation method is simple, the cost is low, the operability is high and the wear-resisting formaldehyde adsorption material can be widely produced and continuously replace an existing material.
