摘　　要：[目的]研究了密度对稻壳-木质剩余物包装箱用复合板性能的影响.[方法]采用混合水平均匀设计的方法,以稻壳与木质剩余物为原料制备包装箱用复合板.对试验结果进行回归分析,讨论密度对复合板2h吸水厚度膨胀率、内结合强度、静曲强度和弹性模量的影响,同时结合密度与芯层比例、表层施胶量、芯层施胶量、热压温度、热压压力和热压时间6因素间的交互效应进行分析.[结果]在优化其他工艺的同时,使复合板在较低密度0.75 ～0.78 g/cm3时各项性能达到国家标准.[结论]该研究为稻壳-木质剩余物包装箱用复合板的研制提供了依据.[Objective] To study the effects of density on properties of the rice-husk/wood-residues packing composite particleboard.[Method] Based on mixed levels uniform design method,the paper used rice husk and wood residues as raw materials for the preparation of packing composite particleboard.Through the regression analysis of experimental results,mainly discussed the effects of density on the thickness swelling,internal bond,modulus of rupture and modulus of elasticity.It also combined density with other main factors such as core layer ratio,surface layer resin consumption,core layer resin consumption,hot-pressing temperature,hot-pressing pressure and hot-pressing time.[Result]It optimized other manufacturing processes,and then made the performance of the composite particleboard reach the national standard at low density,such as 0.75-0.78 g/cm3.[Conclusion] This research provided reference for the development of rice-husk/wood-residues packing composite particleboard.
