摘　　要：采用低分子量酚醛树脂对ACQ防腐后的速生杨木进行浸渍处理、干燥定型后制得改性材。试验表明,ACQ防腐处理对酚醛树脂的浸渍没有影响,PF树脂对杨木具有较好的浸注性,但不同杨木试件的浸注性差异较大。通过分析杨木自身材性及试件不同尺寸与增重率的关系,发现不同的杨木树株和木材纹理对杨木浸注性有显著的影响。The ACQ preservative-treated poplar lumber was modified with PF resin, the resin was fixed in wood by drying. Results show that ACQ has no effect on impregnating of PF, and PF resin could impregnate into poplar wood efficiently and the diversity of impregnation is large. Analyzing the relationships among wood properties and different dimensions with WPG, the impregnation is influenced significantly by different poplar plants and wood textures.
