摘　　要：研究利用无醛豆胶生产杨木/麦秸复合刨花板的制造工艺。采用正交试验设计方法,探讨了施胶量、杨木/麦秸刨花质量比例、热压温度、热压时间等工艺因素对刨花板的静曲强度、弹性模量、内结合强度、吸水厚度膨胀率等性能的影响。试验结果表明:利用无醛豆胶生产杨木/麦秸复合刨花板是可行的,厚度11 mm复合刨花板的优化工艺参数为施胶量14%、杨木/麦秸刨花质量比70/30、热压时间10 min、热压温度170℃。Manufacturing process of poplar-wheat straw particleboard bonded with soybean adhesive was studied in this paper.Orthogonal experiments were carried out to investigate the effects of glue content,poplar-wheat straw weight ratio,hot pressing temperature and hot pressing time on properties of the particleboard,including modulus of rupture （MOR）,modulus of elasticity （MOE）,internal bond （IB） and thickness swelling （TS）.The results showed that it was feasible to prepare poplar-wheat straw particleboard using soybean adhesive.The optimal parameters for 11 mm thick board were：glue content 14%,poplar-wheat straw weight ratio 70∶ 30,hot pressing time 10 min and hot pressing temperature 170℃.
