The present invention belongs to the field of epoxy resin technology, and provides a multi ring aryl hyperbranched epoxy resin and a preparation method thereof. The preparation method comprises the following steps: conducting a branching polymerization reaction between a multi functional epoxy compound and a multi ring aryl diphenol under catalyst conditions to obtain a multi ring aryl hyperbranched epoxy resin; The mass ratio of multifunctional epoxy compounds, polycyclic aromatic diphenols, and catalysts is 100:20-60:0.01-0.02. The present invention also provides a photoluminescence solution containing the resin and an anti-corrosion coating. The polycyclic aromatic hyperbranched epoxy resin of the present invention significantly improves the medium resistance and barrier performance of the coating; Moreover, polycyclic aromatic hyperbranched epoxy resin has intrinsic fluorescence properties, which can predict the failure of steel anti-corrosion coatings; Polycyclic aromatic hyperbranched epoxy resins can also be used for the detection of metal ions.
