The invention discloses an antistatic rubber core-filling rubber shoe rubber material prepared from phosphorus gypsum whiskers and a preparation method. The antistatic rubber core-filling rubber shoerubber material is prepared from the following raw materials in parts by weight: 95 to 115 parts of standard rubber, 2 to 3 parts of sulfur, 1.7 to 2 parts of vulcanization accelerant, 7 to 9 parts ofnano zinc oxide, 11 to 15 parts of stearic acid, 80 to 110 parts of phosphorus gypsum whiskers, 0.4 to 0.6 part of salicylic acid, 18 to 22 parts of high-wear-resistant carbon black, 20 to 25 parts of conducting carbon black, 13 to 18 parts of engine oil and 8 to 12 parts of dibutyl phthalate. The preparation method comprises the following steps: plasticating the number-2 standard rubber in an open-type rubber mixing mill at the temperature of 20 to 50 DEG C until wechsler plasticity is 0.55 to 0.60, adding other formulas such as sulfur and vulcanization accelerator; then uniformly turning and mixing the rubber materi
