Abstract: The process which used H2O2 as oxidation agent to oxidize cassava starch and then modified with Urea-formaldehyde resin and first-drying agent in order to prepare fast-drying starch adhesive was studied systematically in this paper. The stuty showed that this kind of starch adhesive had strong and stability bonding strength,fast-drying property. On the other hand, the process technology was possessed of the prominent virtues such as simple processing equiment,operation conditions controlled easily,no pollution, ect.
