以杨木刨花和无机胶黏剂为主要原料,通过冷压成型工艺制备了无机杨木刨花板,研究了不同施胶量和密度对无机杨木刨花板物理力学性能的影响,通过XRD和SEM分析了不同施胶量及密度对无机杨木刨花板性能的影响机制,同时通过锥型量热仪分析了无机杨木刨花板的阻燃抑烟性能。结果表明:一方面,随着施胶量增大,无机杨木刨花板静曲强度(MOR)和弹性模量(MOE)先增大后减小,同时,内结合强度(IB)逐渐增大,24 h吸水厚度膨胀率(TS)逐渐减小。施胶量为57%时MOR和MOE分别达到最大值21.5 MPa和4 360 MPa,施胶量为65%时IB达到最大值2.61MPa, 24 h TS达到最小值3.36%。随着施胶量增大,燃烧的峰值热释放速率(HRR)降低,...

With poplar particles and inorganic adhesive as main raw materials, inorganic poplar particleboard was prepared by cold pressing technology. The effect of different adhesive consumption and density on physical and mechanical properties of inorganic poplar particleboard was studied. XRD and SEM were used to analyze influencing mechanism of inorganic poplar particleboard's properties with different adhesive consumption and densities. At the same time, the fire retardancy and smoke suppression characteristics of inorganic poplar particleboard were...
