摘　　要：本研究以竹单板和多孔泡沫铝为原料,采用卡夫特AB胶、环氧树脂胶和酚醛树脂胶等三种胶黏剂将竹单板与泡沫铝黏合成型,制备竹单板/泡沫铝夹芯复合板材。探究了不同胶黏剂种类及施胶量对竹单板/泡沫铝夹板材力学性能、吸水性能和胶层形貌的影响。结果表明:采用水溶性酚醛树脂作为胶黏剂,施胶量为340 g·m^(-2)时所制备的板材,其静曲强度、弹性模量及胶合强度均达到最大值,24 h吸水厚度膨胀率和72 h吸水率达到最低值,竹单板和泡沫铝的胶合界面黏合更紧密,证明板材的综合性能最优,最适于工业化生产和实际推广利用。Bamboo veneer and porous aluminum foam were used as raw materials in this study.Bamboo veneer and aluminum foam were bonded by Kraft AB adhesive,epoxy resin adhesive and phenolic resin adhesive,and bamboo veneer/aluminum foam sandwich composite boards were prepared.The effects of adhesive type and sizing amount on mechanical properties,water absorption and morphology of bamboo veneer/aluminum foam clip composite were investigated.The results show that:Using water-soluble phenolic resin as adhesive,the sheet prepared with the sizing amount of 340 g·m^(-2),the static bending strength,elastic modulus and adhesive strength reached the maximum,24h water absorption thickness expansion rate and 72h water absorption rate reached the minimum,and bamboo veneer and aluminum foam adhesive interface bond more closely.It was proved that the comprehensive performance of the sheet was the best.It is most suitable for industrial production and practical popularization and utilization.
