摘要

采用真空-加压工艺对速生杨木进行低分子脲醛（UF）树脂浸渍改性,测试与分析浸渍工艺参数与浸渍改性后杨木增重率、力学强度的关系;并得出浸渍工艺最佳参数为:浸渍温度22,2,5℃、真空度0.07MPa下保持1h、压力0.6MPa下浸渍2h。

Abstract

Modified low molecular urea-formaldehyde（UF）resin was impregnated into poplar samples by a vacuum-pressure impregnation process.The impregnation process parameters and mechanical properties of the samples,as well as impregnated resin amountretained by the samples after processing,were evaluated.The experiments were conducted with impregnation temperatures of 22,2,5℃and a vacuum of 0.07MPa for 1hfollowed by apressure of 0.6MPa for 2h.
