Abstract

  An environmental-friendly soybean protein-acrylate composite adhesive was successfully prepared with the use of soy protein and acrylate by mini-emulsion polymerization. The composition, properties and adhesive performances of the composite miniemulsion adhesive were characterized by Fourier transform infrared spectroscopy (FT-IR), water contact angle (WCA) and bonding strength. Water contact angle measurement showed that the introduction of acrylate increased the hydrophilicity of the composites. Parts of C–O and C=O groups reacted to soybean protein and finally formed carboxyl groups. Besides, bonding strengths of plywood with the amount of acrylate increasing were both higher than 0.7 MPa, which met the GB/T9846-2004 standard about the state of II plywood. Soy protein is bio adhesive, which belongs to environmental-friendly adhesive. However, soybean paste has poor water resistance and corrosion resistance, and not resistant to boiling. This paper used acrylate to modify soybean protein adhesive, and successful preparation of soy protein-acrylate composite adhesive, it could open up a new way for wood adhesives with no release of free phenol nor free formaldehyde. Moreover, could present a new research direction for modification of soybean protein adhesive.
