The invention discloses a mixed dispersing agent for a modified ammonium nitrate fuel oil explosive and a preparation method of the mixed dispersing agent. The mixed dispersing agent for the modified ammonium nitrate fuel oil explosive comprises the following raw materials in percentage by weight: 5-15% of polyethylene glycol, 5-15% of magnesium nitrate, 0.5-5% of a dispersing agent NNO, 0.5-5% of sodium carboxymethyl cellulose, and the balance of water. The preparation method comprises the steps of sequentially adding magnesium nitrate, polyethylene glycol, a dispersing agent NNO and sodium carboxymethyl cellulose into water, and completely dissolving, wherein the next raw material is added when the previous raw material is completely dissolved in water. The method can effectively improve the phenomenon that the modified ammonium nitrate fuel oil explosive is non-uniform in expansion and easy to cake and harden in high-temperature and humid seasons. 本发明公开了一种改性铵油炸药用混合分散剂及其制备方法，所述改性铵油炸药用混合分散剂的原料配比为：聚乙二醇5～15％；硝
