| Abstract: | Ammonium polyphosphate fire retardants is prepared with ammonium dihydrogen phosphate and urea,the way that is ammonium thermal legitimate.The effects of preparation conditions,such as reaction temperature,polymerization time,components proportion is studied with the single-factor test.The results showed that reaction temperature 300℃-320℃,polymerization time 150 min,and molar rate of monoammonium phosphate and urea 1∶1,the products is best performance of fire-retardant and the dgree polymerization is greater. |
