摘　　要：利用速生杨树木材加工剩余物,制备了一种用于运输包装的代木材料,并研究其物理、机械性能。采用正交试验设计方法制备了不同代木包装材料试样,并利用极差分析方法分析了不同工艺参数对代木包装材料物理、机械性能的影响。试验结果表明,制备代木包装材料的较佳模压工艺参数如下：热压温度为120~125℃、热压时间为10 min、热压压力为10 MPa、胶黏剂的添加质量分数为10%,在此工艺条件下制备的代木包装材料,其静曲强度、内结合强度、吸水厚度膨胀率、密度分别为17.7 MPa,1.61 MPa,6.1%,0.73 g/cm3。所制备的代木包装材料满足国家标准（GB/T4897—1992）的A类刨花板一等品物理力学性能要求,是一种绿色环保的包装材料。A wood substitute packaging material was prepared through the breaking, molding and drying of the wood processing residues of fast-growing poplar with its physical and mechanical properties analyzed. Samples of different wood substitute packaging materials were produced via the orthogonal design method, and the influences of different process parameters on wood substitute material＇s physical and mechanical properties were analyzed by the range analysis method.The results of the tests indicated the optimal properties of wood substitute packaging material as the hot-processing temperature being 120~125 ℃, the hot-processing time being 10 min, the hot-processing pressure being 10 MPa and sizing amount being 10%. Under this condition, the MOR, inner bonding strength, thickness swelling rate of water absorption and density of the prepared material were 17.7 MPa, 1.61 MPa, 6.1% and 0.73 g/cm3 respectively. The prepared wood residue packaging products satisfied the requirements of national standard（GB/T4897—1992） and met the standards of green packaging materials.
