摘　　要：以甲基丙烯酸甲酯(MMA)、丙烯酸丁酯(BA)、甲基丙烯酸(MAA)为反应单体,采用乳液聚合法制备一种耐酸碱性和耐水性优良的新型水性丙烯酸树脂。通过单因素与正交实验获得最佳的合成工艺:ω(甲基丙烯酸甲酯)∶ω(丙烯酸丁酯)=2∶3,α-甲基丙烯酸用量为3.7%,乳化剂(OP-10)用量为2.4%,反应温度为80℃,滴加时间为2 h,恒温反应时间为2.5 h。红外光谱及核磁共振氢谱图分析表明,所制备产物的官能团结构与设计目标产物一致。Methyl methacrylate（ MMA）,butyl acrylate（ BA） and methacrylic acid（ MAA） were respectively used as reaction monomer,and a newly kind of water-based acrylic resin with good acid and alkali resistance,excellent water resistance was prepared by emulsion polymerization. Through single factor and orthogonal experimental study,we found the optimum synthesis： ω（ methyl methacrylate） ∶ ω（ butyl acrylate） = 2∶ 3,the amount of α-methacrylic acid is 3. 7%,and the amount of emulsifier（ OP-10） is 2. 4%,the reaction temperature is 80 ℃,the dropwise adding time is 2 h,and the thermostatic reaction time is2. 5 h. The analysis of IR and1 H NMR showed that the structure of the functional group of the product is consistency same as the preparation of the desired product.
