| 摘 要： | 用过氧化苯甲酰(BPO)作为引发剂,引发接枝单体甲基丙烯酸(MAA)与母体环氧树脂E-44在水溶液中共聚制备接枝共聚物,进而用氨水调节其pH值至7～8,制得环氧-丙烯酸接枝共聚乳液,再加入阻燃剂聚磷酸铵(APP)进一步制得水性环氧阻燃涂料。制备水性环氧阻燃涂料的最佳工艺条件为BPO2%(质量分数,下同),MAA6%,APP6%,接枝共聚温度110℃,制备的水性环氧阻燃涂料具有较好的冲击强度(50kg·cm),良好的附着力(1级)和优异的阻燃性能,达到了B1级阻燃热固性塑料标准。

| Abstract: | A graft copolymer was prepared by copolymerized methyl acrylic acid（MAA） and epoxy resin E-44 in aqueous solution initiated by benzol peroxide（BPO）,then adjusted its pH value to 7~8 by ammonium water to prepare waterborne epoxy-acrylic emulsion,and further prepared waterborne flame-retardant epoxy coating with ammonium polyphosphate（APP）.The optimal conditions for preparation of waterborne flame retardant epoxy coating are：BPO 2%（mass）,MAA 6%（mass）,APP 6%（mass）;graft copolymerization temperature is 110 ℃.This coating have good impact strength（50 kg·cm）,favorable adhesion（grade 1） and outstanding flame retardancy（achieve B1 grade in flame-resistant phenolic standard）. |
