Nitrogen-phosphorous fire retardant(NPR) was combined with urea-formaldehyde(UF) resin for preparing plywood samples. Moisture content, bonding strength, immersion-peel performance and fire resistance were tested. The results showed that with 8% of NPR content and 0.2%of NH4 Cl content, the moisture content, bonding strength and qualified rate of immersion-peel test were 7.8%, 0.87 MPa and93%, respectively. The fire retardant performance of the samples met the requirement of the National Standard GB 8624-2012 for the B1 grade.
