摘　　要：叙述了改性氨基树脂湿增强剂的制备及应用。制备的过程包括加成和醚化缩合。分析了湿增强作用机理及化学改性原理，讨论了各种因素对产品性能和贮存稳定性的影响。This paper introduces the preparation and modification of the amino resin as paper wet strength agent and coating water-repellency agent. The process of the preparation is divided into two steps mainly. First one is the addition, re- action and the second is etherifying condensation in week acid medium. It is necessary to add the stabillzator into the system in case of the gelation or aggregation of aqueous dispersed phase. The action mechanism and modifying principle are also discussed.
