The invention discloses an acrylate hydrophilic monomer synthesized by using monoisocyanate polyoxyethylene monomethyl ether, and relates to the technical field of waterborne acrylic resins. The acrylate hydrophilic monomer is prepared from the following raw materials in percentage by mass: 10 to 20% of hydroxyethl acrylate and 80 to 90% of monoisocyanate polyoxyethylene monomethyl ether. The acrylate monomer with hydrophilic groups is synthesized by reacting the isocyanate in the monoisocyanate polyoxyethylene monomethyl ether structure and the hydroxy in the hydroxyethyl acrylate structure; the waterborne acrylic emulsion prepared by the acrylate hydrophilic monomer has good quality stability, is not easy to hydrolyze in the storage process and low in acid value, and the water resistance and the salt spray resistance are better than that of conventional acrylic emulsion. 本发明公开了种利用单异氰酸酯聚氧乙烯单甲醚合成的丙烯酸酯亲水单体，涉及水性丙烯酸树脂技术领域，由如下质量百分比的原料制成：丙烯酸羟乙酯10-20％、单异氰酸酯聚氧乙烯单甲醚80-90％。本发明通过单异氰酸酯聚氧乙烯单甲醚结构中的异氰酸酯和丙烯酸羟乙脂结构中的羟基反应合成带亲水
