三聚氰胺脲醛树脂胶黏剂的合成
Synthesis of melamine-urea-formaldehyde resin adhesive
摘要
Abstract
Six kinds of the melamine-urea-formaldehyde resin ( MUF) were synthesized by adjusting the technology of condensation time and according to the different proportion among the formaldehyde, melamine, urea in this paper. The properties of the resins were detected. The results showed that when the condensation temperature increased from 60℃ to 85℃ , condensation time shorten to 30 min, the resins of the MUF1 - MUF5 were clear and transparent without suspended white particles or stratification phenomenon, only MUF6 still had some suspended particle. The results of the bonding performance test showed that the water resistance of the high molar ratio of F/( M + U) were better than that of low molar ratio, the bonding strength was related to the ratio of F/(M + U)and M/U. The key of improving the water resistance of the MUF was to adjust the proportion of the melamine and formaldehyde.关键词
