摘　　要：采用化学沉淀法对SrAl2O4:Eu2+,Dy3+长余辉发光粉进行二氧化硅包覆改性处理,可以有效改善发光粉的耐水性能,同时对发光粉的长余辉发光特性影响不大。以改性后的发光粉为颜料配置的乳胶漆具有贮存稳定性、耐水性好等优点。SrAl2O4 ： Eu^2 ＋ , Dy^3 ＋ powder were encapsulated with ,silica by chemical precipitation method, which improved the water resistivity with less reduction of persistent luminance. The luminescent latex paints prepared with the modified SrA12O4：Eu^2＋,Dy^3＋ luminous pigments shows good storage stability and water resistance.
