The invention relates to a method for preparing an ultra-high fluidity thermoplastic elastomer material, which is characterized in that the ultra-high fluidity thermoplastic elastomer material is made of the following row materials by the percentage in weight: 10 per cent -50 per cent of polypropylenes, 10 per cent -30 per cent of styrene rubber, 10 per cent -60 per cent of plasticizers, 0.1 per cent -1 per cent of antioxidants, 10 per cent -30 per cent of talcum powers 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 10-15 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 temperature is 150-180 DEG C. The invention has the advantages that the ultra-high fluidity thermoplastic elastomer material is prepared by adopting the novel plasticizer cooperated with the advanced formulation and equipment combination and can be widely used for large-scale products in the field of the automobile, the home furnishings, building and engineering.
