Abstract
For the purpose of controlling fossil resources and reducing hot press temperature for making wood based materials,Tannin-Phenol-formaldehyde (TPF) resin were synthesized with the mimoza tannin of the natural product which included plentiful in the bark of the acacia species.Curing behavior of the synthesized TPF resins was analysed by using a thermo-mechanical analysis (TMA) spring method and examined the bonding property of the plywood with various TPF resins.The 30% TPF and 50% TPF for molar ratio (F/P) 1.2 and 1.4 for phenol replaced of the mimoza tannin were reducedcuring temperature.The resin of molar ratio 1.4 was cured lower curing temperature than that of molar ratio l.2 and a good adhesion performance were recognized.
