摘　　要：利用粉煤灰为原料通过碱熔融-水热法合成沸石,通过对比沸石作防结块剂的防结块效果确定其作防结块剂原料的最佳配量、对磷酸二铵肥效及农作物的影响。实验结果表明:合成的沸石含水量越少,越有利于作DAP防结块剂的效果;当粉煤灰合成沸石作水溶性防结块剂的质量配量比十二烷基苯磺酸钠∶植物油∶沸石为3∶10∶10时,DAP∶沸石为1 000∶1时其防结块性能最优。Zeolite was synthesized by alkali fusion and hydrothermal method using fly ash.The optimumdosage of the anti caking agent, the effect on the fertilizer efficiency and the crops were determined byoptimuming the anti caking effect of zeolite as an anti caking agent. The experimental results show thatthe less water content of synthetic zeolite is beneficial to the effect of DAP anti caking agent. Theoptimal condition of anti caking property is： the mass ratio of sodium sulfonate to vegetable oil andzeolite is 3：10：10, the mass ration of DAP to zeolite is 1 000：1.
