Influence of Three Additives on Curing Properties of Phenol-Formaldehyde Resin
Three different additives(urea,sodium carbonate and triacetin)were selected to be added in phenol-formaldehyde(PF)resin for accelerating curing rate.Curing properties,pot life and shear strength of cure-accelerated PF resins were investigated.The results indicated that the shear strength of plywood made with the PF resin could meet the specifications for typeⅠ plywood according to Chinese National Standard GB/T 9846.3-2004.Sodium carbonate could be more effective considering curing properties,shear strength and pot life.
