对9,10-二氢-9-氧杂-10-磷杂菲-10-氧化物(DOPO)改性合成水性含磷环氧化合物.首先,以酚醛环氧树脂F-51和DOPO(初始F-51环氧基与DOPO摩尔比为3:2)合成出F-51-DOPO加成物.然后,在摩尔比(n (F-51-DOPO的环氧基)/n(MEA))为1:1下.F-51-DOPO加成物与乙醇胺(MEA)反应合成出F-51-DOPO-MEA加成物;最后,在摩尔比(PEGGE环氧基/F-51-DOPOMEA)为2:1下,F-51-DOPO-MEA加成物与聚醚醇二缩水甘油醚(PEGGE)反应,合成了F-5 1-DOPO-MEA-PEGGE加成物.性能研究结果表明,其在室温下能均匀分散于水性体系中,与涂膜中的环氧树脂基材相容性良好;并可使涂膜在保持良好硬度前提下,耐冲击性明显得到提高.热重分析结果表明,其可使固化涂膜在450～800℃高温下的残炭率和耐热性显著提高.氧指数测定结果表明,其能有效提高水性环氧树脂材料的极限氧指数(LOI)及阻燃性能.
