The invention relates to a method for preparing a halogen-free flame-retardant thermoplastic elastomer material, which is characterized in that the halogen-free flame-retardant thermoplastic elastomer material are made of the following row materials by the percentage in weight: 10 per cent -20 per cent of polypropylenes, 50 per cent -60 per cent of ethylene propylene diene monomers, 20 per cent -30 per cent of halogen-free flame retardants, 0.1 per cent -1 per cent of antioxidants, 0.1 per cent -1 per cent of lubricants and 2 per cent -5 per cent of compatibilizers. The preparation method comprises the following steps: the raw materials are scaled and taken according to a weight proportion; all the materials are put into a high mixing machine to be mixed for 2-5 minutes; the materials are taken out; the mixed materials are put into a screw compressor for extruding granulations. The rotating speed of the screw compressor is 180-600r/m and the temperature is 180-200 DEG C. The invention has the advantages that the new halogen-free flame retardant is adopted and matched with an advanced formula design, and the halogen-free flame-retardant dynamically vulcanized thermoplastic elastomer material is prepared, which conforms with demands of environment protection and is widely used in fields of automotive, electronics and electrics, building and engineering. In addition, the invention is especially suitable for replacing rubber components.
