Abstract
The invention provides an aldehyde-free plate. The aldehyde-free plate contains a manganese dioxide catalyst, and a preparing method of the manganese dioxide catalyst comprises the steps of dissolvinga raw material in water and performing a heating reaction to obtain the manganese dioxide catalyst. The raw material comprises potassium permanganate, manganese sulfate and a reducing agent. A bonding agent used by the aldehyde-free plate is urea formaldehyde type bonding agent. The aldehyde-free plate is aldehyde-free, environment-friendly, low in cost, simple in manufacturing process, and capable of effectively preventing or reducing releasing of f ormaldehyde in the bonding agent to the indoor environment.
