The invention discloses an electromagnetic shielding material based on silver fibers and stainless steel fibers. The electromagnetic shielding material is woven from yarn, and with a unit yarn cross-sectional area as one part, the yarn is prepared from 25-65 parts of the stainless steel fibers, 5-10 parts of the silver fibers and 30-70 parts of auxiliary fibers. A preparation method of the electromagnetic shielding material comprises the steps that (1) the stainless steel fibers, the silver fibers and the auxiliary fibers are spun into the 16-40<s>/2 yarn through a siro spinning process; (2) the yarn is adopted as warp and weft and woven by utilizing a rapier or air-jet weaving method and adopting double-layer plain change weaves as a weave mechanism, wherein weaving is conducted in the manner that the inner weaves adopt one-up one-down right twill weaves and the surface weaves adopt one-up two-down right twill weaves. The electromagnetic shielding material can effectively shield electromagnetic waves, the electromagnetic shielding range is 150 MHz-200 GHz, and the warp and weft shielding effectiveness can be greater than or equal to 45 dB.
