摘要
采用对氨基苯甲酸与双酚A型环氧树脂E-44进行反应引入亲水性基团,制得了稳定性良好的环氧树脂乳液。利用红外光谱(FT-IR)、差示扫描量热仪(DSC)、透射电子显微镜(TEM)、激光粒径分析仪等对环氧树脂乳液进行系统地表征和分析。随着对氨基苯甲酸用量的增大,改性环氧树脂的Tg增大,乳液粒径变小,稳定性增强。
An epoxy resin emulsion with good stability was prepared via reaction of bisphenol A epoxy resin E-44 with p-aminobenzoic acid to introduce hydrophilic group into epoxy resin. The product was characterized and analyzed by IR, DSC, TEM and so on. With the increase of amount of p-aminobenzoic acid, the Tg of modified epoxy resin was increased, the particles size of epoxy resin emulsion was diminished and its stability was improved.
