中文摘要：

以双酚A型环氧树脂（E-44）为基础树脂、丙烯酸（AA）为改性剂，合成了溶剂型环氧丙烯酸树脂（EA），探讨了合成工艺条件（反应温度、反应时间、催化剂和阻聚剂用量）对AA转化率的影响．在此基础上，通过顺丁烯二酸酐（MA）与EA上的羟基反应，在EA上引入了羧基亲水性基团，制备了水性环氧丙烯酸树脂（EB）．结果表明：当反应温度为95℃、反应时间为4．5h、催化剂和阻聚剂用量分别为1．5％和0．075％（与E-44的质量比）时，AA的转化率为98．27％．EB合成的最优工艺条件为：反应温度80℃，反应时间1．5h．采用傅里叶红外光谱分别对中间产物EA和目的产物EB进行结构表征，进一步证实AA与E-44开环酯化生成了EA，MA与EA上的羟基发生酯化反应生成了EB．

英文摘要：

By using bisphenol-A epoxy resin （E-44） as the basic resin and acrylic acid （AA） as the modifier, solvent-based epoxy acrylate （EA） was synthesized, and the effects of reaction temperature, reaction time, catalyst content and inhibitor content on the AA conversion were discussed. Afterwards, waterborne epoxy acrylate （EB） was synthesized via the reaction of hydrophilic carboxy groups in maleic anhydride （MA） with the hydroxyl groups in EA. The results indicate that, when the mass ratios of the catalyst and the inhibitor to E-44 are respectively 1.5% and 0. 075% , the polymerization results in a AA conversion up to 98.27% at 95℃ for 4. 5h; and that the optimal temperature and time for EB synthesis are respectively 80℃ and 1.5 h. It is also demonstrated by the FT-IR spectra of EA and EB that the formation of EA is due to the ring-opening esterification of AA with E-44, while that of EB is due to the esterification of MA with the hydroxyl groups in EA.
