摘　　要：采用物理包覆的方法,分别用甲基硅油、液态石蜡对聚磷酸铵(APP101)进行疏水性包覆处理,讨论了改性剂的种类和含量对APP101水溶性以及对水性防火涂料耐水性能的影响。实验结果表明:甲基硅油、液态石蜡的包覆作用降低了APP101的水溶性;当甲基硅油含量2%、液态石蜡含量4%时,改性后的防火涂料在水中浸泡48 h无起泡现象。Modified ammonium polyphosphate （APP101） with methylsilicone oil and liquid paraffin coating layer are prepared in physical encapsulation. The water solubility of APP101 and the influences of modificatory APP101 on the water resistance of fire-retardant coating are investigated. The results show that physical encapsulation with methylsilicone oil and liquid paraffin lead to a decrease in water solubility of APP101. Fire-retardant coatings possesses better water resistance after adding 2% methylsilicone oil or 4% liquid oaraffin.
