The invention discloses a manufacturing method of rubber leather. The manufacturing method comprises the following steps of: a, carrying out gluing on one surface of a to-be-coated rubber layer of crust leather, paving the rubber layer under a large press vulcanizer after the glue is dry, with the surface with glue facing upwards; b, paving the rubber layer after vulcanization on the embryo leather, wherein the thickness of the rubber layer is 0.2-0.5 mm; c, downwards pressing a mould at high temperature of 130-150 DEG C for 5-6 minutes; and d, lifting the mould, and sorting after cooling so as to use. The technical scheme is adopted, the manufacturing method provided by the invention has the following advantages that manufactured rubber leather shoes are not light-reflecting, stand wear and tear and are easy to care, thus being suitable for using on occasions such as mines and battlefields.
