摘要
将氮磷型阻燃剂(NPR)与脲醛树脂胶(UF)混和后,应用于阻燃胶合板的制备,探讨NPR添加量对胶合板含水率、胶合强度、浸渍剥离性能及阻燃性能的影响。结果表明,当阻燃剂添加量8%,固化剂添加量0.2%时,胶合板的含水率为7.8%,胶合强度达0.87 MPa,浸渍剥离合格率达93%,阻燃性能达到GB 8624-2012《建筑材料及制品燃烧性能分级》的B_1难燃级。
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.
