Embodiments of the invention provide a protective liquid for preventing the surface of a steel material from rust corrosion and a preparation method thereof. The preparation method comprises the following steps: weighing 70 to 140 g of oleic acid and 17.5 to 70 g of dimercaptothiadiazole, pouring the above-mentioned components into a tank body, setting the tank body under a condition of a temperature of 170 DEG C to 205 DEG C, maintaining the temperature for 17 to 26 hours, cooling a mixed liquid obtained by firing to a normal temperature, proportioning the mixed liquid and dimethicone according to a weight ratio of 0.7% to 2%, and carrying out uniform mixing under stirring at a normal temperature so as to obtain the protective liquid for preventing the surface of the steel material from rust corrosion. The protective liquid provided by the invention has the advantages of few constitution components, good rust corrosion prevention effect and long rust prevention period. 本发明实施例提供一种钢材表面防锈蚀保护液及其制备方法，包括：取油酸70～140
