Abstract

The invention discloses a formaldehyde absorbing agent. The formaldehyde absorbing agent is prepared from, by mass, 20-23 parts of tannin, 3-4 parts of diisopropylbenzene hydroperoxide, 15-18 parts of deacetylated chitin, 5-6 parts of iron white powder, 12-14 parts of calcium carbonate powder, 5-6 parts of barium stearate, 2-3 parts of 10, 10'-oxybis-phenoxarsine, 3-4 parts of acetylation diacid double starch sodium, 15-16 parts of nitromethane, 10-12 parts of aniline, 6-7 parts of edible seaweed powder, 8-9 parts of diatomite, 10-12 parts of nanometer titania, 5-6 parts of aluminium oxide and 60-62 parts of deionized water. The raw materials of the formaldehyde absorbing agent are subjected to a chemical reaction and a synergistic effect, and the formaldehyde absorbing rate is significantly improved compared with an existing formaldehyde absorbing agent; various functions of moisture absorption, deodorization, mildew and fungus resistance and the like are achieved, no secondary pollution is produced, the product is stable in performance, good in dispersity and long in storage time.

Description

technical field [0001] The invention relates to a formaldehyde absorbent and a preparation method thereof, belonging to the field of air purification. Background technique [0002] With the development of the economy and the improvement of people's living standards, a large number of new houses have been built, and the interior decoration has become more and more exquisite. my country's "Indoor Air Quality Standards" stipulates that the maximum allowable concentration of formaldehyde in the living room is 0.10mg / m 3 , the vast majority of newly renovated homes have indoor formaldehyde concentrations exceeding the standard by several to ten times within 5 to 10 months after the renovation is completed. Residents usually adopt relatively passive methods such as opening windows for ventilation or waiting for a period of time to live again, causing extreme damage to life. Big inconvenience. [0003] Formaldehyde has a strong stimulating effect on human skin and mucous membrane...
