Abstract

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.

Description

technical field [0001] The invention relates to the field of adsorption materials, in particular to a wear-resistant formaldehyde adsorption material and a preparation method thereof. Background technique [0002] Formaldehyde purification adsorbent refers to the adsorption material mainly used to absorb formaldehyde in household life, mainly including: activated silicon, activated carbon, activated alumina. [0003] When the concentration of formaldehyde is relatively high (for example, the new house has just been renovated), the method of ventilation can be used to discharge the formaldehyde outside, but physical methods such as ventilation can only reduce the concentration of formaldehyde, and cannot completely remove formaldehyde. [0004] The formaldehyde in the adhesive is released slowly, and the time to eliminate formaldehyde is longer, and the release period is as long as 3-15 years. The daily manifestation is that after a long time in the new house, when the door o...
