摘　　要：单板/高密度纤维板(HDF)复合木地板结合了实木地板和浸渍纸层压木质地板的优点,是地板产业发展的新方向之一。文中以12mm厚HDF为基材、复合意杨单板,试制了"耐磨纸-单板-HDF基材-平衡纸"四层结构地板用复合板材。研究了不同单板厚度、胶黏剂种类(聚氨酯-PU,脲醛树脂-UF)及涂布量对板材翘曲度、吸水厚度膨胀率、内结合强度及机加工性能的影响。结果表明:1)单板与HDF复合制造木地板是可行的;2)复合木地板的翘曲度随单板厚度和施胶量的提高而递增,最高可达约0.6%;3)贴面采用聚氨酯胶黏剂,产品性能优于脲醛树脂胶合板材,但冷压周期偏长。推荐工艺条件为:单板1.2mm,PU或UF胶黏剂均可,涂布量控制在100g/m^2左右。Veneer/HDF composite laminate flooring（VCLF） is a new floor product in collection of advantages of both solid wood and impregnated paper overlaid laminate flooring（IPLF）.Four-layer VCLF was made of wear-resisting paper,poplar veneers,12mm-thiek HDF,and balance paper.Influences of different veneer thickness,adhesive types（PU,UF）,and resin contents on the flooring properties（including warping,thickness swelling,inner bond strength,and machining performance） were explored.Test results showed that：（1） manufacture of VCLF was technically feasible;（2） warping of the flooring was increased with veneer thickness and/or resin content increasing, its max value was up to about 6%;（3） PU-glued VCLFs showed better performances than UF-bonded products, while it costs longer cold pressing time.Recommended processing conditions were：veneer thickness 1.2mm, PU or UF adhesive at a content spread of about 100g/m^2.
