The invention belongs to the technical field of casting material processing, and discloses a gray cast iron material based on antimony element improvement and a preparation method and application thereof. The gray cast iron material comprises the following chemical components in percentage by weight: 3.20%-3.50% of carbon; 1.70% to 2.60% of silicon; 0.45% to 0.90% of manganese; 0 to 0.18 percent of phosphorus; 0 to 0.15% of sulfur; 0.030% to 0.035% of antimony; and the balance iron. The preparation method comprises the steps that raw materials except antimony are put into an electric furnace to be smelted, antimony is added to be smelted after more than three times of slag removal, and antimony is fully diffused; then a silicon iron inoculant is added for inoculation treatment; the molten iron temperature is controlled to be gt; and discharging at 1490 DEG C, and casting to obtain the improved gray cast iron material based on the antimony element. By adding the antimony element, the mechanical property and ma
