The formaldehyde catching agent is prepared from, by mass, 2-6 parts of sodium sulfite, 4-8 parts of hydrochloric acid, 20-40 parts of native starch slurry, 5-10 parts of sodium hydroxide, 3-9 parts of sodium sulfate, 2-6 parts of epoxypropane, 20-25 parts of tannic acid, 3-5 parts of diisopropylbenzene hydroperoxide, 14-17 parts of deacetylated chitin, 4-6 parts of titanium dioxide, 10-13 parts of calcium carbonate powder, 4-6 parts of barium stearate, 14-16 parts of nitromethane, 11-14 parts of phenylamine, 9-11 parts of diatomite, 4-6 parts of aluminum oxide, 6-8 parts of diatomite composite catalysts, 10-14 parts of graphite powder, 8-10 parts of p-phenylenediamine, 4-6 parts of phenol, 6-8 parts of ferric chloride and 60-100 parts of deionized water.

Description

technical field [0001] The invention relates to a formaldehyde scavenger 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 / m3. Most of the newly renovated homes have indoor formaldehyde concentrations that exceed the standard by several to ten times within 5 to 10 months after the completion of the decoration. Usually adopt methods such as relatively passive opening window to ventilate or wait for a period of time to live again, cause great inconvenience to life. [0003] Formaldehyde has a strong stimulating effect on human skin and mucous membranes, and can cause selective damage to vi...
