The invention discloses a preparation method for a halogen-free flame-retardant high-density polyethylene/ethylene-vinyl acetate polymer. The preparation method specifically comprises the following steps: I, adding 2 to 4 parts by weight of silane coupling agent into 180 to 220 parts by weight of anhydrous alcohol, mixing the silane coupling agent and the anhydrous alcohol uniformly, heating the mixture to 70 to 90 DEG C, adding 100 parts by weight of dried expandable graphite into the solution, and stirring to obtain modified expandable graphite; II, uniformly mixing 5 to 15 parts by weight of modified expandable graphite, 70 parts by weight of high-density polyethylene, 30 parts by weight of ethylene-vinyl acetate polymer, 2.5 to 7.5 parts by weight of ammonium polyphosphate and 2.5 to 7.5 parts by weight of red phosphorus flame retardant master batch in a mixer to obtain a mixture; III, mixing and granulating the mixer by using a screw extruder, drying the extruded granules and performing injection molding on the dried granules. The prepared composite material has high flame retardant property and high mechanical property.
