The purpose of the research was to prepare environment friendly plywood using starch adhesives modified by blocked isocyanate. Blocked isocyanate and auxiliary agent were used to modify starch. The influence factors of the bonding strength and water resistance of starch adhesive were studied by different solid content, adding additives and adding blocked isocyanate. The results show that starch and blocked isocyanate adhesive to join the ratio of 100/20, the dry bonding strength the most, while the starch adhesives and the ratio of blocked isocyanate to join 100/25, the wet strength the most. Bonding strength and water resistance was improved significantly by adding additives and isocyanates to starch adhesive. Plywood bonding strength from the performance of integrated cost considerations, the optimum ratio of additives added 4% and 6%. (C) 2011 Published by Elsevier Ltd.
