| Abstract: | A low toxic urea-formaldehyde resin(UF)which was modified by melamine was synthesized in preparing process of UF. The results showed that the solid content was 49.88% and the free formaldehyde content was 0.202 6% for low toxic UF. The statictuneintensity was 22.6 MPa, elastic modulus was 2 056 MPa, interior bonding strength was 0.58 MPa and thickness expanded ratio after absorbing water 2 h was 2.57% for the bamboo particleboard pressed by low toxic UF adhesive. The low toxic UF was an adhesive for wood wi... |
