摘　　要：以镁系无机胶粘剂和均匀混合的麦秸和木材碎料为原料,采用热压工艺,制备麦秸/木材均质复合无机碎料板。利用导热系数测定仪、锥形量热仪对比研究了普通有机胶粘剂胶合麦秸板、麦秸无机碎料板、木材无机碎料板以及麦秸/木材均质复合无机碎料板的阻燃抑烟性能。结果表明,与普通有机胶粘剂胶合麦秸板相比,无机胶粘剂能显著降低板材的热释放和烟释放;麦秸/木材均质复合无机碎料板的热释放速率(HRR)、总热释放量(THR)、烟生成速率(SPR)、总烟生成量(TSP)和质量损失均高于麦秸无机碎料板而低于木材无机碎料板,点燃时间(TTI)小于麦秸无机碎料板而大于木材无机碎料板,麦秸/木材均质复合无机碎料板具有良好的阻燃抑烟性能。With Mg-based inorganic adhesive and uniform mixed particles of wheat straw and wood as materials？ inorganic particleboard with a uniform mixture of wheat straw and wood was prepared by hot-pressing technology. Cone calorimeter and thermal conductivity measure instrument were used for the comparative study of flame retardancy and smoke suppression of ordinary wheat straw particleboard？ wheat straw inorganic parti-cleboard？ wood inorganic particleboard and inorganic particleboard with a uniform mixture of wheat straw and wood. The results show that compared with ordinary wheat straw particleboard,inorganic adhesive can significantly reduce the release of heat and smoke. Heat release rate（H R R ） ,total heat release（TH R ） 9 smoke production rate（SPR） ？ total smoke production （TSP ） and mass loss of inorganic particleboard with a uniform mixture of wheat straw and wood are higher than wheat straw inorganic particleboard but lower than wood inorganic particleboard and time to ignition（TTI ）o f that is shorter than wheat straw inorganic particleboard but longer than wood inorganic particleboard,indicating that inorganic particleboard with a uniform mixture of wheat straw and wood has a good effect on flame retardancy and smoke suppression.
