The present invention adds tetramethylol glycoluril which is a four functional monomer having four methylol groups (-CH_2OH) into an amino-based(urea-formaldehyde or melamine-urea-formaldehyde) adhesive which has super E0 (KS standard) of emission amount of formaldehyde used to generate a fiberboard and a particle board, thereby improving physical properties of the fiberboard and the particle board of high density and low density. |
