The present invention is applicable to the technical field of foam materials, and provides an antistatic and flame-retardant expandable polyolefin foam material and a preparation method thereof. The antistatic and flame-retardant expandable polyolefin foam material comprises the following raw materials in parts by weight: a resin matrix, an antistatic masterbatch, a flame retardant, a foaming agent and a compatibilizer. The preparation method of the antistatic and flame-retardant expandable polyolefin foam material comprises the following steps: blending and extruding polyolefin, MBS and zinc stearate in a twin-screw extruder in parts by weight to obtain a resin matrix masterbatch; mixing the resin matrix masterbatch, antistatic masterbatch, flame retardant and compatibilizer in parts by weight in an internal mixer to obtain a premix; and feeding the premix and foaming agent into a twin-screw extruder for melt extrusion. The present invention modifies a polyolefin material by cooperation of the resin matrix masterbatch, antistatic masterbatch, flame retardant, compatibilizer and foaming agent to prepare an antistatic and flame-retardant expandable polyolefin foam material with excellent antistatic and flame-retardant effects.
