Abstract

The present disclosure provides a modified deodorant urea-formaldehyde (UF) resin and use thereof, as well as a particleboard and a preparation method thereof, and relates to the technical field of wood-based panels. Raw materials for preparing the modified deodorant UF resin provided by the present disclosure include: melamine-modified UF resin (MUF), aluminum ammonium sulfate dodecahydrate, wax, and water. Raw materials for preparing the MUF include: urea, formaldehyde, and melamine. When the modified deodorant UF resin provided by the present disclosure is used to prepare wood-based panels, the aluminum ammonium sulfate dodecahydrate losses 12 crystal water during hot pressing to form a metastable structure NHAl(SO), in which NHcan react with the formaldehyde to reduce formaldehyde emission, and NHand Alcan absorb hydroxyl groups of organic substances to form hydrogen bonds to reduce odor of the wood-based panels.
