The rotational rheometer was used to study the effect of modified glue, soybean meal and G reagent on the viscoelastic behavior of two-component soybean meal based adhesive. The results showed that the change trend of curing viscoelasticity of the two-component soybean meal based adhesives was not affected by the modified glue, always G′〉 G″; with the increase of adding amount of soybean meal, the viscoelasticity of two-component soybean meal based adhesives increased gradually. The thermal stability of cross-linking products gradually weakened in high temperature area. With the increase of the amount of G reagent, the gelling behavior was strengthened and the gelling temperature decreased gradually. Through the comparison of UF resin, PF resin and two-component soybean meal based adhesives, the gelling behavior, shear strength and water resistance two-component soybean meal based adhesive were located between the results of UF resin and PF resin.
