Abstract

Abstract:

Phenol-melamine-urea-formaldehyde（PMUF） resin adhesive was prepared by adopting urea and melamine as the modified monomer for phenol formaldehyde resin. The effects of the molar ratio of folmaldehyde，phenol，urea， melamine and sodium hydroxide on performance of PMUF resin adhesive were studied. It was characterized by DSC and¹³C-NMR. The results indicate that the PMUF can reduce the content of free formaldehyde， and it can make wood-based panel with high water resistance and weatherability. The properties of PMUF resin adhesive are best when the molar ratio is 3.1∶1∶0.7∶0.3∶0.5 (formaldehyte∶phenol∶urea∶melamine∶NaOH) and the best curing temperature is 135.5 ℃.

Key words: phenol, urea, melamine, PMUF resin, adhesive
