The invention relates to a preparation method of an additive of low-acid-value anti-wear hydraulic oil, after the additive of the anti-wear hydraulic oil prepared by the method is added into the hydraulic oil, the hydrolytic stability of the hydraulic oil is obviously improved, and the additive has the characteristic of low acid value, and can be used in complexing agents with relatively high requirements on acid values, such as steam turbine oil and the like. 本发明涉及一种低酸值抗磨液压油的添加剂的制备方法，通过本方法制备的抗磨液压油的添加剂添加进液压油后明显提高了液压油的水解安定性能，且其具有低酸值的特点，可以在对酸值要求比较高的复合剂中使用，比如汽轮机油等。
