摘要
为拓展低密度人造板的应用领域,以杨木刨花和可发泡聚苯乙烯为原料制备复合材料（芯材）,并在其表面贴覆杨木单板制成木质复合板,以提高板材的力学性能。结果表明,当复合板的密度在0.42~0.48 g/cm3时,板材的内结合强度和静曲强度达到国家标准A类刨花板二等品的要求,导热率低于0.050 W/（m.K）,可用于家具、室内装饰的非受力部件及墙体保温材料。
In order to expand the application of low-density wood-based panels, the authors developed a new kind of composite by using poplar particles and foamed polystyrene. Veneers were further overlaid on the composite to improve mechanical properties. The results showed that the bonding strength and modulus of rupture of the composite panels were greatly enhanced while density was maintained at 0.45 g/cm3. Mechanical properties of the composite panels met the A-grade requirements for Chinese National Standard GB/T 4897.1-2003 so that the panels could be used for furniture making, interior decoration and thermal insulation.
