摘要：

使用响应曲面法研究尿素添加次数和尿素添加时间间隔对脲醛树脂性能和其板材性能的影响，使用傅里叶红外光谱仪定性分析尿素添加次数和尿素添加时间间隔对脲醛树脂主要基团的影响。结果表明：尿素添加次数和尿素添加时间间隔对脲醛树脂的固体含量及固化时间影响不大，而对黏度、树脂中羟甲基含量、游离甲醛含量、各主要基团含量和板材的性能有很大影响。树脂合成工艺中2次添加尿素，间隔时间20 min时，树脂和板材性能比较好。

Abstract:

The effect of urea addition number and interval on the performance of urea-formaldehyde resins and the properties of plywood were studied by response surface methodology for the first time. The main chemical groups were qualitative analyzed using FTIR for exploring the effect of urea addition number and interval on these groups. The results showed that the solid content and curing time of UF (urea-formaldehyde) resins can not be notably affected by the number of additions and the interval of urea. and the viscosity, hydromethyl content, free formaldehyde content of the UF resins and properties of plywood were prominently affected by the number of additions and the interval between additions of urea. The main chemical groups of UF resins were influenced by the number of additions and the interval of urea. When the number of additions were two and the interval of urea was 20 min, the performance of UF resins and the properties of plywood were better.

Key words: urea, ureaformaldehyde(UF) resins, response surface methodology, FTIR
