Abstract:
The chemical structure,polymerization characteristics of the commercial one-component polyurethane were analyzed with 13C NMR.The viscoelastic properties of bonded joints,ambient creep and shear properties of glulam beams were evaluated by thermomechanical analyses.The results showed that one-component polyurethane displayed a significant temperature-dependent creep,and the ambient creep was not the main factor because it was inhibited.The equilibrium moisture content(EMC) of the wood before and after bondi...
Keywords:polyurethane adhesives  green wood gluing  TMA  NMR  plywood creep character
