Fabrication and Characterization of Carboxylated Lignin Sulfonate Modified Epoxidized Soybean Oil Wood Adhesive Cured by Maleic Anhydride
In this work, a formaldehyde-free bio-based wood adhesive was successfully fabricated using epoxidized soybean oil (ESO) cross-linked with maleic anhydride (MA) and carboxylated lignin sulfonate (CLS). The effect of CLS substitution dosage on the bonding performance was systematically investigated. The results indicate...
