以麦秸、木材和环保阻燃无机胶黏剂为主要原料,通过麦秸和木材碎料均匀混合的方式,采用热压工艺制备麦秸/木材均质复合无机碎料板,研究了麦秸与木材的配比、施胶量、热压时间和热压温度对板材性能的影响,并通过X射线衍射仪、扫描电镜分析了其对板材性能的影响机制。结果表明,随着麦秸与木材配比减小,板材静曲强度（MOR）、弹性模量（MOE）和内结合强度（IB）逐渐增大,2h吸水厚度膨胀率（TS）逐渐减小,优选配比为m（麦秸）∶m（木材）=4∶6。随着施胶量的增大,板材的MOR、MOE先增大后减小,IB逐渐增大,TS逐渐减小。施胶量为63%时,板材的MOR、MOE分别达到最大值15.5 MPa、3 110 MPa,此时,IB、TS分别...

With wheat straw, wood and environmentally friendly and flame retardant inorganic adhesive as major raw mate-rials, inorganic particleboard with a uniform mixture of wheat straw and wood was manufactured by hot-pressing technology. The effect of wheat straw-wood ratio, adhesive consumption, hot-pressing time and hot-pressing temperature on physical and mechanical properties of the board was studied, and influencing mechanism of them on the board's properties was analyzed by X-ray diffraction (XRD) and scanning electron microscopy (SEM). Results showed that modulus of rupture (MOR), modulus of ...
