高浓度甲醛制备脲醛树脂及其性能分析
Synthesis of urea-formaldehyde resin based on high concentration formaldehyde, and its properties
摘要
Abstract
A urea-formaldehyde resin ( UF) was prepared with high concentration formaldehyde.The structure characteristics and thermal mechanical properties of this UF were observed by 13 C-NMR and DMA.The results showed that this UF resin had high solid content and bonding strength of particle board improved 50%.And, the reaction between urea and high concentration formaldehyde was fully.13 C-NMR and DMA results indicated that methylol content was 31.0%, however, it was just 23.7% in the ordinary formaldehyde prepared UF resin.And the methylene ether bond content increased double that mean condensation degree of this UF resin was improved.Finally, the bonding strength of this resin was improved significantly.关键词
