摘　　要：使用乳白胶制备了刨切薄竹贴面稻草板,并分析了其物理力学性能。结果显示,饰面板材具有优异的静曲强度和弹性模量及良好的表面胶合强度,能够耐温水浸渍,但不能够耐热水浸渍;使用电镜观察了饰面板材的微观形貌,并对饰面材料进行了红外光谱分析,进一步揭示了饰面板材的性能,微观裂缝及亲水性基团的存在使得饰面板材在高温高湿的环境条件下,更易被水作用而失去胶合性能。薄竹饰面薄型稻草板,具备了薄竹优美的颜色与花纹,同时也具备了稻草刨花板优异的物理力学性能,能够作为室内装饰材料及非承重包装材料而得到广泛使用。The rice-straw particleboard overlaid with sliced bamboo veneer was manufactured with PVAc,and the physical and mechanical properties were studied.The results showed that the MOR and MOE of the overlaid particleboard were excellent,and the surface bonding strength was good.The particleboard could have warm water resistant and not have hot water resistant.The micro-morphology of overlaid particleboard was observed by SEM,and the FT-IR of materials was analyzed.The micro-cracks and hydrophilic groups made the particleboard lost bonding property under the condition of high temperature and humidity.The overlaid particleboard has the bamboo＇s beautiful color and texture,and also has the excellent physical and mechanical properties of rice-straw particleboard,so it can be widely used as interior decoration material and non-load-bearing packaging material.
