| 摘 要： | 以UF树脂压制多层胶合板的甲醛释放量和湿胶合强度为指标,通过正交试验确定合成工艺的主要参数:F/U的终摩尔比、缩聚阶段pH值、加成阶段三聚氰胺(M1)的质量分数,探讨了它们与甲醛释放量以及湿胶合强度的关系,优化出最优方案。压制出七层杨木胶合板性能达到GB/T9846—2004中Ⅱ类指标要求,同时甲醛释放量达到E_0级要求。

| Abstract: | A low toxic environment-friendly UF resin for plywood was prepared.Taking formaldehyde emission and wet bonding strength of the resin-bonded plywood as evaluation index,the authors of this paper determined through orthogonal test the main parameters(final molar ratio of F to U,medium pH in condensation stage and melamine percentage by mass in addition stage.) for the UF synthesis.Also,the relationship between the parameters and the evaluation index was discussed,and the experiment design was optimized.The p... |
