The invention relates to a styrenic resin blend having a three-layer-structured particle and a preparation method thereof. The preparation method comprises the following steps: polymerizing, by weight, 100 parts of a vinyl aromatic compound, 0.1 to 10 parts of an initiator, 2 to 10 parts of an emulsifier, 100 to 300 parts of deionized water and 0.1 to 10 parts of a cross-linking agent at a temperature in a range of 50 to 85 DEG C so as to obtain a core seed emulsion; reacting 15 to 70 parts of the core seed emulsion, 0.1 to 10 parts of the initiator, 2 to 10 parts of the emulsifier with 80 to 300 parts of deionized water and 30 to 85 parts of butadiene or other rubber monomers to obtain a two-layer particle emulsion; and allowing 40 to 90 parts of the two-layer particle emulsion, 10 to 60 parts of monomers of the vinyl aromatic compound, 10 to 60 parts of monomers of a vinyl cyanide compound, 0.1 to 10 parts of the initiator, 2 to 10 parts of the emulsifier and 80 to 300 parts of deionized water to react so as to obtain the blend. The blend has impact strength of 300 J/m and tensile strength of 53 MPa.
