The invention relates to the field of petrochemical coatings, in particular to a water-based epoxy micaceous iron oxide intermediate paint for an outer wall of a storage tank and a preparation method of the water-based epoxy micaceous iron oxide intermediate paint. The water-based epoxy micaceous iron oxide intermediate paint for the outer wall of the storage tank is formed by blending a component A and a component B according to the mass ratio of (5-8): 1, and the component A comprises water-based epoxy emulsion, water, water-based organic bentonite, anti-rust pigment, pigment filler, mica powder, micaceous iron oxide gray and auxiliaries; the component B is a waterborne epoxy curing agent; the waterborne epoxy emulsion is formed by emulsifying liquid epoxy resin, the epoxy equivalent is 540-650, and the solid content is 55 +/-5%; the waterborne epoxy curing agent is a polyamine adduct, the amine hydroxyl equivalent is 400-450, and the solid content is 50 +/-2%.
