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水溶液中加入其质量2%的水性固化剂906得到粘缸剂CA-21。采用^(1)HNMR、^(13)CNMR、FTIR、GPC、TG对HE-32、PA236和PA236G进行了表征和性能测试,对CA-21进行了薄膜性能和力学性能的测试。结果表明,聚合物已成功合成,且PA236已成功接枝到HE-32上。PA236G的热稳定性大幅提高,CA-21的平均剪切强度可达0.17311 MPa,对基材的平均附着力可达171.2 N,分别约是市售产品1(主要成分为改性聚酰胺环氧氯丙烷树脂)的2.06倍和1.84倍,具有作为粘缸剂使用的潜力。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 ^(1)HNMR,^(13)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.
