Abstract

To improve the internal bonding strength and water resistance of particle board using a soy protein-based adhesive, soy protein was treated with alkali and urea; then phenol formaldehyde resin was added to produce a soy protein-based adhesive （SPF）. The SPF adhesive was added to the particle board with and without a cross-linker and followed by copolymerization to study its mechanical properties and thickness swelling rate of water absorption. Analysis included Fourier Transform Infrared （FT-IR） spectroscopy and Differential Scanning Calorimetry （DSC）. Results indicated that adding the SPF adhesive with the cross-linker before copolymerization had better water resistance, which met the GB/T 9846.3－2004 standard for particle board structures in a humid environment （10.0%）. With preshrinking phenol formaldehyde as a cross-linker, the internal bonding strength of the particle board met the standards used in furniture and interior decoration requirements （0.40 MPa）. The FT-IR and DSC results showed that the cross-linker agent mainly reacted with primary amine. DSC results also showed a strong reaction between the cross-linker and the protein. It inferred that adding cross-linker before the copolymerization was very important, which could improve the internal cohesion of soy protein-based adhesive.［Ch, 2 fig. 1 tab. 9 ref.］
