Interpretive Summary:

Technical Abstract: The interests on biobased wood adhesives have been steadily increased in recent years. Used pilot-scale produced water washed cottonseed meal (WCSM), we optimized the bonding parameters to meet the criteria of both operational flowability and shear strength of bonded wood specimens. We first tested the optimal conditions of protein and fiber residual in WCSM for better bonding performance. We then formulated WCSM adhesives to improve the adhesive performance and operation conditions (parameters). Plywood panels were made for the purpose of the non-structural interior application. The plywood panels were evaluated by three strength measurements (dry, wet, and soaked shear strength). The protein content had a significant effect on properties and adhesion performance of cotton protein adhesives. The high pressing temperature (170 °C) gave a positive effect on adhesion property of all three strength measurements. Protein and fiber residual also had significant effects on the thermal property, bonding performance, and morphological properties of cotton protein adhesives.
