Interpretive Summary:

Technical Abstract: Cottonseed protein has the potential to be used as renewable and environmentally friendly adhesives in wood products industry. However, the industry application was limited by its low mechanical properties, low water resistance and viscosity. In this work, urea modified cottonseed protein adhesive was studied and compared with a commercial available urea formaldehyde (UF) resin. The ratio of urea and cottonseed protein, synthesis conditions of adhesive, press parameters, and adhesion shear strength were studied. The function groups developed in the UF/Cottonseed protein adhesive was studied with Fourier transform infrared spectroscopy (FTIR). The adhesion developed was studied with atomic force microscope (AFM). The results illustrated that wood veneer bonded with the urea modified cottonseed protein has comparable properties as with UF resin. Therefore, the urea modified cottonseed protein adhesive can be an alternative to UF resin for wood composite products.
