摘要 以液态环氧树脂E-51和乙二胺为原料,成功制得一种水性环氧固化剂,并用冰醋酸中和成盐。通过控制冰醋酸的加量,调节产物的亲水亲油值,使其能与自制的水性环氧树脂乳液复配制备环氧树脂涂料;并研究了固化剂与乳液的相容性。采用FT-IR、1H-NMR、环氧值表征固化剂结构。测试了涂膜的动态力学性能、热力学性能、平衡吸水率、耐酸碱性、铅笔硬度等。结果表明:当中和度为50%时,涂膜的力学性能、耐水性、耐酸碱性、硬度均较好。

Abstract: A kind of waterborne epoxy curing agent has been successfully prepared by liquid epoxy resin E-51 and ethylenediamine as raw materials. The curing agent is neutralized with glacial acetic acid to form a salt. The HLB of the product is adjusted by changing the amount of the added glacial acetic acid, which makes it possible to mix the epoxy resin coating with a self-made aqueous epoxy emulsion. The compatibility of the curing agent with self-made waterborne epoxy resin emulsion is studied. The structure of the curing agent was characterized by FT-IR, 1H-NMR and epoxy value. The coating is tested by means of equilibrium water absorption, dynamic mechanical properties, acid and alkali resistance, pencil hardness and other testing methods. The results show that the mechanical properties, apparent properties, water resistance and acid and alkali resistance of the coating are good when the degree of neutralization is 50%.
Key words:  waterborne epoxy    curing agent    Emulsion    neutralization    compatibility
