摘　　要：以麦秸碎料为主要原料，采用漆酶水浴与干法两种不同处理方法压制麦秸无胶碎料板，研究热压温度、热压压力和热压时间对板材物理力学性能的影响。试验结果表明：影响麦秸无胶碎料板物理力学性能的主要因素是热压温度；水浴处理方法压制碎料板的物理力学性能优于干法压制的碎料板；漆酶水浴处理方法较优的热压工艺参数为漆酶用量43．6U／g，含水率10％，热压温度170℃，热压压力3-4MPa，热压时间20～25min。With wheat straw as the raw materials, self-bonding flake boards can be produced with two different methods, the laccase water-forming processing and the dry-forming processing, and the effect of hot-pressing temperature, hot-pressing time and hot pressure on the physical and mechanical properties of flake boards is studied. The experimental result shows： the main factor influencing the physical properties of wheat straw self-bonding flake boards is hoty-pressing temperature; the physical properties of the flake boards produced with the water-forming processing are better than with dry-forming processing; the optimal process parameters for the laccase water-forming processing are lacease amount 43.6U/g, moisture content 10%, hot-pressing temperature 170~C, hot-pressing pressure 3-4MPa and hot-process time 20-25min.
