摘　　要：研究了低游离甲醛含量脲醛树脂的合成工艺条件,采用添加三聚氰胺、聚乙烯醇和醚化的方法,对脲醛树脂进行改性,以降低游离甲醛的含量,保持其稳定性和硬挺效果。探讨了甲醛/尿素摩尔比、反应温度、pH值等因素对脲醛树脂综合性能的影响。通过FTIR、Zeta电位和SEM测定,表征了脲醛树脂的结构和性能。结果表明,经三聚氰胺和聚乙烯醇改性并醚化后的脲醛树脂,游离甲醛含量低、综合性能好。The synthetic technology conditions of urea-formaldehyde resin with low free formaldehyde were studied. The urea-formaldehyde resin was modified by using melamine,polyvinyl alcohol and etherification to reduce the content of free formaldehyde, maintaining its stability and stiffness effects. The factors including formaldehyde/urea molar ratio, reaction temperature, and pH value to the effects of urea-formaldehyde synthesis performance were discussed. The configuration and performance were characterized by FTtR and SEM. The experimental results showed that the content of free formaldehyde of the modified urea-formaldehyde resin was tow, and performance was good.
