The invention relates to an ester emulsifying agent used for an industrial emulsion explosive and a preparation method thereof. The ester emulsifying agent comprises an oily group component, a linking group component, a polar group component and a base oil component, the mol ratio proportion of the oily group component to the linking group component to the polar group component is 1:1-2:1-4, the oily group component, the linking group component and the polar group component react to generate polyolefine acid ester, then the polyolefine acid ester is diluted by using the base oil component, and the weight proportion of the polyolefine acid ester to the base oil component at the time of dilution is 1:0.8-1.2. The preparation method comprises the following steps that: in an alkylation process, the oily group component is put into a reactor and is heated, then the linking group component is put into the reactor, the temperature is kept, the mixture is stirred for 0.5-1 hour, the temperature is raised to 200-240 D
