The invention provides a preparation method for polyester cord yarn. The preparation method is characterized by comprising the following steps: (1) spinning process flow; (2) impregnation process flow. The preparation method can effectively improve the breaking strength and the breaking elongation of the conventional polyester cord yarn, thereby improving the impact resistance of the polyester cord yarn. The invention further provides the polyester cord yarn prepared by adopting the method; the breaking strength of the polyester cord yarn is greater than or equal to 6.5 cN/dtex, the breaking elongation rate reaches 19-25%, the breaking work is far higher than that of the conventional polyester cord yarn, and the dimensional stability (DSI) is greatly improved compared with that of nylon cord yarn. The invention further provides application of the prepared polyester cord yarn in diagonal tires.
