摘要
用二元酸与玉米淀粉进行酯化反应，制成半酯化玉米淀粉悬浮液，对ＵＦ树脂进行改性．胶合含水率１６％～１８％的单板，生产的胶合板物理力学性能符合ＧＢ９８４６．１～１２—８８的标准要求，同时使ＵＦ树脂水和性良好，便于清洗涂胶设备．
UF resin was modified with the semiesterific corn starch suspension liquid made from esterification of dibasic acid and corn starch.The physicalmechanical properties of the plywood manufactured with moisture content of 16%18% glue veneer comformed the standard of GB9846.11288.The hydrophilic nature of UF resin revealed good,thus,this was convenient for cleaning coating equipment.
