Study on Alfalfa Protein-Based Adhesive Modified by Sodium Hydroxide

In this study, alfalfa protein modified by sodium hydroxide was used to prepare adhesive. The effect on the bonding property by adding different amount of sodium hydroxide was discussed. The upper limit using temperature of alfalfa protein-based adhesive was increased and its bonding property was improved after the protein modified by sodium hydroxide. The adhesive prepared by alfalfa protein modified by 6% sodium hydroxide had the best bonding strength of 2.5MPa.
