摘　　要：为了更好地利用单板加工剩余物,采用三聚氰胺改性脲醛树脂胶制备杨木单板条层积材(PSL),探讨涂胶量、热压工艺及板材密度等工艺因子对板材性能的影响。在本试验条件下,较优工艺参数为:涂胶量(双面)300g/m^2、热压温度130℃、热压时间75 s/mm、板材密度0.60 g/cm^3,制备的PSL物理力学性能优良,甲醛释放量低于GB 18580-2001中E1限量值(≤1.5 mg/L),可用作室内装饰装修用材。In order to better use waste veneer, the authors selected waste poplar veneer from a plywood production line and a melamine-modified urea-formaldehyde resin to make parallel strand lumber（PSL）. The experimental factors studied included glue consumption,hot pressing temperature,hot pressing time and panel density. The properties of the PSL were then tested. The results showed that optimal manufacturing technology parameters obtained were 300 g/m^2 glue, 130 ℃ hot-pressing temperature, 75 s/mm hot-pressing time and 0.60 g/cm^3 panel density. The physical and mechanical properties of the PSL made by the optimal manufacturing technology parameters were excellent with less than 1.5 mg/L formaldehyde emissions, which met the E1 specification of the national standard GB 18580-2001.
