摘　　要：不施加任何胶黏剂,通过添加阻燃剂聚磷酸铵(APP)制造阻燃无胶高密度蔗渣碎料板。探讨APP含量对板材物理力学性能的影响,并利用热重分析和锥形量热分析对阻燃板材进行燃烧性能的表征。结果表明:APP的加入使板材强度有所下降,但板材强度仍能满足室内结构用板的标准要求;APP有效地抑制了蔗渣的受热分解,促进成炭;APP有效抑制了阻燃板燃烧时的热释放和烟释放。Without any adhesives, developed fire-retardant high-density binderless particleboard from bagasse by adding flame retardant ammonium polyphosphate（APP）.Explore the relationship between APP application amount and the board properties, and using TGA and CONE to investigate the combustion performance of flame retardant binderless particleboard.The results showed that：the addition of APP reduce board strength, but still meet the national standard GB/T 4897.4—2003.APP effectively suppresses thermal decomposition of bagasse, promote char formation.Addition of APP effectively inhibited heat release and smoke release of the board.
