Phenolic Resin Modified Soybean Protein Adhesive
A phenolic resin prepolymer has been prepared first with the balance performance of bonding strength, especially the water-resistant strength, and flowability for modification. Then soy protein gel is blended with the phenolic rein prepolymer, effects of some factors, such as mixed mode, mixing temperature, mixing system PH, mixing ratio, on the bonding strength are investigated. Results show that the dry strength of the Catalpa wood Sample can reach to 7.6 MPa, while water-resistant strength can reach to 1.3 MPa.
