摘 要:
本试验以苯酚、三聚氰胺、甲醛为主要原料合成了PMF共缩聚树脂。研究考查了各原料配比对PMF树脂性能的影响，取n（F1）／n（P）、n（M）／n（P）、n（F2）／n（M）、n（NaOH）／n（P）为4个因素，对其进行优化试验，从而得到最佳优化配方。本试验合成的PMF树脂性能优良，用其压制的竹帘胶合板物理力学性能达到JG／T1．56-2004所规定的竹模板物理力学性能要求。并且，原料成本较PF树脂低，仅为竹胶合板用2122型PF树脂的66．1％左右。[著者文摘]

Abstract:
The experiment synthesized PMF resins was taking phenol, melamine, formaldehyde as main materials. The influence of inverse proportion on capability of PMF were investigated. We choosed four factors： n （ F1 ）/n （ P）, n （M）/n （P） , n （ F2 ）/n （M） , n （NaOH）/n（P）, and carried through optimized examinations. A best directions for synthesizing PMF resin was found consequently. The properties of PMF resins that we synthesized in the experiment were wonderful. Properties of veneers bonded with PMF can mcas- me up JG/T 156 -2004. And the cost of materials is lower than that PF, just was 66.1% of the cost of PF.[著者文摘]
