摘　　要：采用自主研发的无机胶黏剂,制备杨木单板增强秸秆板,进行了单因素试验和正交优化工艺试验。结果表明,涂胶量和热压工艺对试板的静曲强度、弹性模量、表面结合强度、浸渍剥离长度影响明显;采用优化工艺制备的复合板,其静曲强度,弹性模量、表面胶合强度和浸渍剥离长度,分别达到GB/T 18103-2013《实木复合地板》和GB/T15104-2006《装饰单板贴面人造板》要求。Straw boards reinforced with poplar veneer were manufactured with inorganic adhesives developed by the authors.Optimal process parameters were obtained by orthogonal experiments.Testing results showed that glue spread,hot pressing temperature,time and pressure all significantly influenced properties of the samples.Within optimal experimental parameters,modulus of elasticity,modulus of rupture,surface bonding strength and delamination of the samples could meet the requirements of National Standard GB/T 18103-2013 parquet and GB/T15104-2006 decorative veneered wood-based panels.
