The invention discloses an antibacterial and antistatic EVA (ethylene-vinyl acetate) / starch / PE (polyethylene) composite foaming material and a preparation method thereof. The antibacterial and antistatic EVA / starch / PE composite foaming material is prepared by: subjecting completely degradable starch and EVA, PE, a compatibilizer, as well as an elastomer to blending in a Banbury mixer, and adding functional additives, i.e. an antibacterial agent and an antistatic agent, and an inorganic filler, a cross-linking agent, a foaming agent and other aids. According to the invention, the antibacterial agent and the antistatic agent are blended into the foaming material, and the formula is scientific and reasonable, so that the product has both antibacterial and antistatic properties, and can satisfy life and some special environments.
