摘　　要：通过核壳乳液聚合工艺引入环氧树脂,对丙烯酸酯乳液进行改性,制备了水性环氧/丙烯酸酯杂化乳液。通过接触角、极化曲线测试以及傅里叶变换红外光谱(FT-IR)、热重分析(TGA)、电化学阻抗谱(EIS)等方法对改性前后的丙烯酸酯进行了表征。结果表明,以12%环氧树脂改性的丙烯酸酯与改性前的丙烯酸酯相比,其疏水性、热稳定性和耐蚀性能都有较大的改进。A water-based epoxy-acrylate hybrid emulsion was prepared by core-shell emulsion polymerization with epoxy-modified acrylate emulsion.The acrylate before and after modification were characterized by contact angle and polarization curve measurements,as well as Fourier transform infrared（FT-IR） spectroscopy,thermogravimetric analysis（TGA） and electrochemical impedance spectroscopy（EIS） techniques.The results proved that the hydrophobicity,thermal stability and corrosion resistance of the acrylate modified by 12% epoxy resin are improved evidently,as compared with the unmodified acrylate.
