Waterborne epoxy adhesive derived from epoxidized soybean oil and dextrin: Synthesis and characterization

摘要

In the present study, waterborne epoxy (WBE) was prepared and the parameters involved in the synthesis of WBE have been optimized based on physicochemical analysis. A dextrin-based curing agent (DCA) was synthesized from dextrin and trimellitic anhydride at variable molar ratios, reaction temperature, reaction duration, and solvent. Furthermore, the optimized composition of DCA and WBE system was used as adhesive in wood bonding. A comparative analysis of DCA-cured-bonded system was studied with phenol-formaldehyde (PF)-bonded adhesive system. From all the analyses, the performance characteristic WBE-DCA adhesive system was found comparable with that of PF-bonded system.
