摘要:以丙三醇三缩水甘油醚和二甘醇为原料,合成了水性超支化环氧树脂 HE-32。以己二酸和二乙烯三胺为
原料,合成了水性聚酰胺 PA236,将其接枝到 HE-32 上得到了改性水性聚酰胺 PA236G。向 PA236G 水溶液中加

Abstract: Waterborne hyperbranched epoxy resin (HE-32) was synthesized using glycerol triglycidyl ether
and diethylene glycol. Waterborne polyamide (PA236) was synthesized from adipic acid and diethylene
triamine and then grafted onto HE-32 to obtain modified waterborne polyamide PA236G. Finally, creping
adhesive CA-21 was prepared by adding 2% (based on the mass of PA236G aqueous solution) waterborne
curing agent 906 into PA236G aqueous solution. HE-32, PA236 and PA236G were characterized and tested

by HNMR, CNMR, FTIR, GPC and TG. The film properties and mechanical properties of CA-21 were
tested. The results showed that the polymer was successfully synthesized and PA236 was successfully
grafted onto HE-32. The thermal stability of PA236G was greatly improved. The average shear strength of
CA-21 could reach 0.17311 MPa, the average adhesion to the substrate could reach 171.2 N, which was
about 2.06-fold and 1.84-fold of commercial product 1 (mainly modified polyamide epichlorohydrin resin),
respectively, indicating that CA-21 had the potential to being used as creping adhesive.
