The invention discloses a breathable antistatic foam material and a preparation method thereof. The foam material comprises the following raw materials in parts by weight: 100-120 parts of low-density polyethylene, 10-15 parts of glycerin monostearate, 3-8 parts of talcum powder, 3-5 parts of an antistatic agent, 1-3 parts of flame-retardant particles, 3-5 parts of a foaming agent and 1-3 parts of a nucleating agent. The antistatic agent and the flame-retardant particles are prepared in the preparation process, the antistatic agent is prepared by performing esterification reaction on an intermediate 5 and an intermediate 6 to prepare an intermediate 7 and polymerizing the intermediate 7, and the antistatic agent can increase the volume conductivity of the foamed plastic, so that static electricity accumulated in the foamed plastic can be conducted out in time, and theantistatic effect is thus achieved; the flame-retardant particles generate a coke layer on the surface of the material when the foamed plastic i
