摘　　要：试验研究了以尿素和磷酸为原料生产聚磷酸铵 (简称APP)的工艺过程及工艺条件 ,讨论了反应时间、反应温度、配样比、引发剂的加入量对聚磷酸铵聚合度的影响 ,得到了在此实验范围内最佳工艺条件 :T =2 2 0℃ ,反应时间τ =3h ,配样比为 :H3 PO4(85 % )∶CO(NH2 ) 2 =1∶1.8。The technology processes and technology conditions were studied on producing hydrophobicity from urea and phosphate. The effects of reaction time、temperature of reaction、reagent proportioning、initiating agent adding quantum were discussed. The optimum technology conditions can be gained in the range of experiment: T=220 ℃,reaction time τ=3 h,reagent proportioning: H 3PO 4(85 %):CO(NH 2) 2=1∶1.8.
