The invention discloses a preparation method of a sintered integral mechanical press molded breathable functional element, which adopts a large-tonnage press for integral mechanical press molding of the breathable functional element, the breathable element is sintered in a two-time mechanical press molding mode of integral pre-molding and secondary molding, and the integral mechanical press cancels a secondary compounding process of a sheet air brick and a dispersion air brick. The service performance of the whole machine-pressed breathable functional element is effectively improved, the problems that a currently-used breathable element pouring product is low in strength, poor in stability and prone to breakage, and the air permeability is affected are solved, and the breathable element pouring product has the advantages of being high in strength and density, good in thermal shock resistance and molten steel erosion resistance and good in air permeability; therefore, the service life of the whole machine pres
