摘　　要：制定了红麻秆(Hibiscus cannabinus)材料在无任何添加剂的条件下制作无胶碎料板的相关工艺,探讨了红麻杆无胶碎料板的密度与其物理力学性能(静曲强度、内结合强度、吸水厚度膨胀率)间的关系,根据国家标准GB/T4897.2-2003干燥状态下使用的普通刨花板要求评价了红麻杆无胶碎料板的性能,结果表明:当密度大于0.7g/cm3时,红麻秆无胶碎料板的性能即能够满足标准要求。并使用傅里叶红外光谱研究了其在热压过程中的官能团变化,进而初步分析红麻秆无胶碎料板的胶合机理。Study was made on manufacture technology of binderless particleboard from kenaf （ Hibiscus cannabmus ） stalk without any additive under high temperature and pressure. The detection of tested boards demonstrated that mechanical properties, including bending strength, internal bond strength and thickness swelling rate increased with density of the board, and when board density reached 0.7 g/cm^3, it showed that the tested board met the requirements of the national standard. And change of functional groups during the hot press process was studied with the fourier transform infrared spectroscopy to discuss the self-bonding mechanism ofkenaf stalk binderless particleboard.
