Abstract:

Based on the synthetic route of L.tartaric acid, phosphoric acid chloride and a very small amount of phosphoric acid as catalyst, diacetyl tartaric acid was prepared. As being the produce modifier, the ethanol solution of diacetyl tartaric acid was been added into the low concentration soy protein isolate pretreatment solution of pH10.50-10.90 for the preparation of adhesive. The physicochemical properties, solid content, bonding strength, DSC and SEM of adhesives was tested, under the best conditions of pH10.70-10.80 with the ethanol solution of 0.4 g diacetyl tartaric acid per 10 mL, the adhesive had good water resistance and the bonding strength more than 2 MPa. The bonding strength of new adhesive surpassed the national standard II of plywood bond strength (≥0.7 MPa)
