| 摘 要： | 用己内酰胺作改性剂,通过正交实验设计考察了甲醛和三聚氰胺摩尔比(F/M)、溶液pH值、反应温度(T)和反应时间(t)对可发性三聚氰胺甲醛(MF)树脂的储存期、固含量、黏度、MF泡沫密度及泡孔尺寸均匀性的影响,运用综合评分法和综合平衡法对正交实验结果进行了分析,得出最优水平组合:F/M=2.5,pH=8.0,T=90℃,t=60min。最优条件下合成的MF树脂可发泡性良好,制得的泡沫性能优良。

| Abstract: | The effects of mole ratio of formaldehyde and melamine (F/M),solution pH,reaction temperature (T) and time (t) on the properties of foaming melamine-formaldehyde (MF) resin with caprolactam as modifier were investigated by orthogonal experiment where solid content,viscosity and storage time of the MF resin,density and size uniformity of the MF foam were used as performance evaluation parameters. The results of the experiments were analyzed by using the comprehensive scoring method and the integrated balance method. The optimum formula of preparation was obtained as follows:F/M=2.5,pH=8.0,T=90℃,t=60min. The MF resin prepared under the optimal conditions could be foamed well and the properties of the foam were good. |
