以麦秸碎料和无机胶黏剂为主要原料,通过冷压成型工艺制备了无机麦秸碎料板,研究了麦秸碎料添加量对无机麦秸碎料板物理力学性能的影响,并通过X射线衍射仪、热重分析仪、差示扫描量热仪及扫描电镜等分析仪器分析了麦秸碎料添加量对无机麦秸碎料板性能影响机理.结果表明:随着胶草比增加,板坯养护期间,麦秸碎料对无机成分水化反应的“隔阻”效应减弱,无机麦秸碎料板坯中无机成分水化反应速度加快,反应更完全,结晶更完整,无机胶粘剂生成量增加,麦秸碎料与无机胶粘剂接合界面性能变好,无机麦秸碎料板的IB逐渐增大,TS逐渐减小,MOR和MOE先增大后减小,板材热稳定性增加.综合考虑,优化的胶草比为2.1.

　　With wheat straw and inorganic glue as main raw materials,inorganic wheat-straw particleboard was prepared by moulding pressing technology.The effect of Adding Different Level wheat straw on physical and mechanical properties of inorganic wheat-straw particleboard was studied.X-Ray diffraction(XRD),Thermogravimetric Analyzer(TGA),Differential Scanning Calorimetry(DSC)and Scanning Electron Microscope(SEM)were used to analyze influencing mechanism of Adding Different Level wheat straw.The results show that inhibition effect of wheat straw to ...
