Abstract:
In order to improve the bonding strength of soybean adhesive in the polar plywoods immersed in water，a kind of adhesive was prepared by modifying the soy protein isolate with anion detergen θ.The effects of the ingredients as well as hot-pressing temperature on the bonding strength of the adhesive in the polar plywoods were investigated.Thermal transition properties and alternation in chemical groups of soybean adhesive were evaluated by DSC and FTIR technologies respectively.The results showed that，the soybean adhesive exhibited the greatest bonding strength when the hot-pressing temperature was 160℃，the mass ratio of θ to SPI was 2.5wt%，and SPI to water was 1 to 10.The thermal reaction of the adhesive during the boding process mainly completed below 160°C;the concentrations of O-H and N-H bonds in the structure of the adhesive decreased when anion detergen θ was applied.After modifying with anion detergen θ，the bonding strength of soybean adhesive in the polar plywoods immersed in water was improved remarktedly.
