High-fluidity and high-shape-retention PE (polyethylene) material as well as preparation method and application thereof

The invention relates to a preparation method of a high-fluidity and high-shape-retention PE (polyethylene) material as well as a preparation method and application of the PE material. The preparation method comprises the following steps: S1, mixing terpene resin and liquid paraffin, heating, and adding PE resin to obtain a first mixed solution for later use; heating EVA resin, adding a ferrocene catalyst, and reacting to obtain a second mixed solution for later use; s2, mixing the first mixed solution and the second mixed solution, reacting, and plastifying under the conditions that the magnetic field intensity is 1-1.5 T and the temperature is 30-60 DEG C, so as to obtain the PE material with high fluidity and high shape retention. The high-fluidity and high-shape-retention PE material prepared by the preparation method is high in thermal stability, so that the high-fluidity and high-shape-retention PE material has good fluidity; the hollow winding pipe made of the material is small in wall thickness deviat
