In this study, the waterborne hyperbranched epoxy resin (HE-32) is synthesized using glycerol triglycidyl ether and diethylene glycol , the waterborne polyamide (PA236) is synthesized using adipic acid and diethylene triamine, then graft PA236 onto HE-32 to get modified waterborne polyamide PA236G, finally, 2~4% waterborne curing agent is added to obtain the creping adhesive CA-21. The analysis of HE-32, PA236 and PA236G using 1H-NMR, 13C-NMR, FTIR and GPC confirmed that the polymer was successfully synthesized and PA236 was successfully grafted onto HE-32; The thermal properties of the three products have been tested by thermogravimetric analysis, and the thermal stability of PA236G has been greatly improved. Finally, the film performance and mechanical properties of CA-21 were tested. The results showed that the average shear strength of CA-21 can reach 0.17 MPa, and the adhesion to the substrate can reach 171.16 N, which proved it has the potential to be used as a viscous agent.
